There are several types of car steering wheel locks (see the previous report on the classification of locks), and there are also many brands of products, and perhaps only the armor lock can be called "customized fashion beauty." First of all, the form is beautiful. The entire lock of the armor lock is completely wrapped by a leather holster, which is very strong and durable. It feels very good. There is no metal surface on the outside of the lock to contact the steering wheel, so the steering wheel will not be scratched. At the same time, the leather looks luxurious and beautiful, enhancing the owner's aesthetic taste. Second, the quality is beautiful. As the saying goes, beauty is not only beautiful, but the most important thing is the inner beauty. As a lock, it must be safe and reliable. The internal structure of the armor lock is extremely durable and reliable. Only one part of the lock cylinder will be damaged and the other parts will not be damaged. Experience has taught us that the lock cylinder will not be damaged under normal use. Again, use beauty. In addition to quality, the lock is easy to use. Use the armor lock for 20 to 30 seconds to lock it. It is as easy to use as the new old steering wheel lock, but after half a year of old steering wheel lock, it will be difficult to expand and contract, and it is necessary to add lubricant, which is easy to soil the hand and steering wheel. The armor lock does not use the fragile rotating and telescopic components, and it will never be difficult to expand and contract, and it will last for a long time. Fourth, lock the beauty. The anti-theft lock of the armor lock is placed on the dial of the steering wheel. As long as the car thief uses violence to destroy the armor lock, the end of the armor lock mounted on the steering wheel will touch the horn and press the disc to sound an alarm. If the car thief uses violence to saw off the steering wheel, the armor lock cannot be removed. Because the lock fork locks the lock on the spokes of the steering wheel, the front and rear two high-hardness steel plates protect the spokes and their sides. steering wheel. At the same time, the lock handle protrudes 40 cm from the steering wheel, and the top handle and its connecting portion are welded with reinforcing ribs, and are not easy to be sawed. At the same time, the armor lock is very different from other car anti-theft locks due to its burly shape. The thief feels that it is difficult to start, and it is difficult to retreat, so as to avoid making the inside of the car unrecognizable. With multiple color choices, the owner can choose the right color match according to the style of his car interior. Fifth, the price is beautiful. After reading the above report, you must feel that this armor lock is so great, the price must be very expensive. The anti-theft ability of the armor lock is comparable to that of imported car anti-theft locks, and even surpasses the performance of some imported car anti-theft locks, but its price is the same as that of other domestic brands, only selling domestic prices, in contrast, A lock has a very high price/performance ratio. Sixth, the character is beautiful. In addition to the anti-theft performance, the armor lock can protect the personal safety of the driver and passenger. If you are a female driver, with such a sturdy self-defense weapon, I believe that the key moments can guarantee you. At the same time, if the vehicle is wading or if you can't open the door in case of other accidents, it can help you when you break the glass. The steering wheel lock of the car is about the safety and health of yourself and your family. When you buy it, you can't take it lightly, and you can't buy it cheaply. You can buy some products that you can't use. In order to make your family feel more at ease, it is recommended that you purchase a secure and safe steering wheel lock like a lock.

Jinan Languang Electromechanical has successfully developed the first domestic automotive interior parts atomization tester, providing scientific and efficient testing tools for automotive industry manufacturers to choose the ideal interior materials. Under the action of high temperature, the volatile components in the automotive plastic interior materials evaporate and condense on the windshield or the window, which may cause poor line of sight and affect driving safety. Jinan Languang's new FT-F1 atomization tester is designed according to the German DIN 75201 standard. The high-temperature acceleration is used to complete the evaporation process. The simulated car is placed under sunlight, so that a certain material can be quantitatively analyzed. The degree of atomization of glass and windows. At the same time, the test results can also help to determine the amount of toxic and harmful substances in the sample; and can help to determine the degree of influence of the atomization of the xenon headlamps on the illumination.

Car interiors, the next battlefield for competition [In the future, Chery will not let go of an unsatisfied car. Chery will have to work hard in the interior of the car to make the interior fully up-to-date. This work has now begun. In the second half of this year, consumers will Can experience a 'fine' Chery." This is the chairman of Chery Yin Tongyao recently to the media state. "I admit that Chery's first three products have a rough side. In addition to considering the return of funds, after the product is offline, we too need to let it quickly enter the market, too need to hear the feedback of customers, too need to know the peer Its evaluation." Yin Tongyao used three [too" to explain the reasons for the [precaution" of the previous product. "Roughness" has affected the continued high-speed growth of Chery's market share. "Roughness" has, to some extent, damaged the reputation of the Chery brand. Chery did not have the words and art, and dared to admit his inadequacies. When reporters asked other car manufacturers whether they encountered the same problem, they almost euphemistically admitted that they are: "Our manufacturing process still has a gap with foreign countries, and the interior design of products is a weak link." The issue raised by the reporter seems to be too advanced. It seems that the sophisticated design of the interior is a late-maturing variety that consumers need to wait patiently. According to the survey, out of the 55 new cars that were listed on the domestic market in 2003, only a handful of cars had interiors as selling points. Only in the Elysee SX/VTS (leather upholstery/metal feel interior style), Guangzhou Honda New Accord (upholstery has a big upgrade), and 03 Nissan new bluebird (interior luxury) and other products appear in the selling point column Interior wording. However, in the international sports arena, design war has already moved to interior design. According to overseas media reports, the international automotive design community is following the design trends of Japanese companies with a sincere attitude. Because the interior of the Japanese car is exquisite, the design performance is outstanding, and this design feature has long been transformed into the most direct competitiveness of the Japanese models in expanding the territory on the international sports car. The three major automotive groups in the United States compete with Japanese companies in high-end interiors. They cater to the preferences of consumers and add to their cars all the refinement, anger and devotion of European cars. A car designer once said to reporters: [The most likely car design is the interior design. The appearance of the car is for others to see. What people really enjoy is the interior design of the car." From a styling design perspective, interior design accounts for more than half of all vehicle designs. Because of the relative complexity of the interior design, the components involved are relatively numerous. To design a product's interior is as complicated as the car's shape design. Interior products include dashboards, steering wheels, seats, control buttons, air conditioning outlets, shifter heads, door trims, door handles, and more. At the same time, the interior design must match the shape design. Although there are many concept cars that are beautiful in shape, the interior design is inconsistent with the shape, which affects the coordination of the aesthetics of the vehicle and greatly reduces the aesthetic appearance. The insiders often know at a glance that it was not done by a group of designers, and at least not communicated well. In terms of job characteristics, interior designers mostly come from product designers, because the interior products are mostly close-contact, so the design needs to consider more details and need more delicate, and emphasizes the sense of touch, feel, Comfort, visibility and more. For automotive interior design, Du Baonan, director of automotive design and design at Design Balance Industrial Design, has deep feelings. He believes that, from the development trend in recent years, the trend of international trends in interior design is more and more tend to digital and high-tech, modeling tends to be simple, neat, and pay more attention to the application of a variety of materials, collocation. From the perspective of the development of the design language, the development trend of the international design style from 1997 to 2000 was that the automotive design language influenced and guided the product design style. From 2001 to 2004, due to the advent of the digital age, the widespread use of high-tech digital products (such as digital communication products and video audio/video products) has greatly influenced the trend of car design. The style of product design has begun to guide and influence the car. The design style of the vehicle. Many interior design elements of a concept car (such as buttons/buttons, display sections, backlight design, etc.) are similar to home appliances, computer products, and communication products. "In developed countries in Europe and the United States, most consumers prefer a simple design style. Products with beautiful shapes and simple styles will appear in every corner of their lives. This style will become an aesthetic standard in their lives." Du Baonan This way he evaluates the tastes of European and American consumers he is familiar with. For the tastes of consumers in developing countries, he believes that in Asian countries, it may be because of population-intensive reasons. People do not have the concept of sparsely populated countries in Europe and the United States. They prefer to have a lot of details and even luxurious arrangements. Use these to highlight your personality. As far as the domestic situation is concerned, consumers do not consider the proportion of interior quality when buying a car. Many models have made adjustments after entering China, removing high-tech parts and adding decorative parts such as peach wood trim and leather seats to reduce costs. The Japanese knew the Chinese consumer psychology very well, and thus did a lot of articles in the interior design, starting from the decoration, adding some useless configurations such as bright plating, peach wood decoration to confuse consumers. In fact, in a sense, these things are very common, but they can also prove that most people are "pursuing luxury." The main reason is that cars are only just beginning to be popular in China. Most consumers don`t know much about cars, they don`t know how to choose them, and it`s not clear how to evaluate and test whether the layout is reasonable and whether the interior quality is good or bad. As long as other brands have configurations, their own cars are just as good. As the popularity of automobiles continues to increase, this phenomenon will change. Consumers will eventually choose to design a good, comfortable product. As a specific user, they have much more time to touch the interior of the car than the shape of the car. Whether interior design is good or bad (including design, material comfort, layout, conformity with usage habits, etc.) will directly affect his use and even mood. In this sense, the interior design of the car is particularly important. People all say that we can't survive without being [showing" right now. However, in the opinion of reporters, this involves the cultural differences of the nation, and the emphasis on functioning is still heavy. It requires careful scrutiny at specific times. In any case, Chery's ability to openly admire the interior is a good thing, but it is important to first touch the preferences of the people. (Liu Yuanna) Car interior enters the era of extreme decoration gap is less than 1 mm The major automobile companies in the world have been trying their best to improve the quality of products, increase their competitiveness, and please consumers. In these kinds of efforts, an important part is the improvement of interior quality. Mr. Greg Bernas is the project executive manager of Toyota Motor and an automotive engineer. His full-time job is to reduce the gap between the car interior and the car body, such as the gap between the door and dashboard of the glove box, or the gap between the lid of the cup holder and the central storage box, and so on. Today, these tiny details have become a very important indicator of the quality of car interiors. Those gaps around car audio, air conditioning devices, and door handles have become narrower and narrower, and they are increasingly being used by car manufacturers as proof of superior quality. Bernas believes that with the narrowing of the overall quality gap between different brands of cars, automotive interiors have become a new battleground for competition. The ultimate goal of this war is to fully match the interior parts of the car to zero distance. According to JDPower's report, car interiors have been overall improved over the past five years. The problem report for the first three months after the purchase of a new car has dropped a lot. These issues include annoying friction, or less prominent carpeting. Between 1998 and 2003, the interior quality of American car brands rose the fastest. The interior problems of the 100 models dropped from 25.0% in 1998 to 17.2% last year. The European automotive company, the same indicator is reduced from 30.6% to 23.5%. Toyota and its luxury brand Lexus have been the front runners in the interior. In the JDPower interior quality report, Lexus ranked first in the past six years. At the just-concluded Chicago Auto Show, Toyota set a new goal for his colleagues. On its 2004 So-lara, Toyota announced that the gap between the car interiors has been reduced from the old 1.5 mm to 0.5 mm. Don Esmond, senior vice president and sales division of Toyota Americas, said that such high precision requirements will give customers a very high quality and exquisite feel. More importantly, such an accurate match will be maintained over a long period of time. Although 1 mile of 1 gallon of oil is not a big achievement in terms of fuel economy, for the interior, a gap of 1 mm is a remarkable thing. Bob Lutz, vice president of product development at General Motors, acknowledged: [We are really lagging behind Japanese companies in this area, but we are learning." He said that the advent of Buick La Crosse this fall will be an excellent testimony. Buick La Crosse represented our first major move to improve interiors to achieve the best interior levels in Japanese cars. He said La Crosse's rich interior material texture and wood grain will hopefully bring a positive impact to the Buick brand. Lutz hopes that Buick will become the United States Lexus, providing the highest quality car possible within the price consumers can afford. This is one of the strategies that Mazda is using. The Mazda B series pickups also intend to provide consumers with high-quality interiors on a low-cost basis. Jeremy Barnes, a spokeswoman for Mazda, said that because consumers cannot spend more than $30,000 to buy a car, there is no reason not to get high-quality interiors. Because only the interior is the item that the driver always feels after getting on the bus. Ford`s interior design guide, Reichman, said comparing the Ford`s new Mustang`s interior with the older interiors shows how much energy we`ve spent on interior quality improvements in the new model, including Ford`s last year. The investment in decoration improvements is three times that of previous years. The quality of the material used in the new Mustang, the degree of docile material, and the distinction between different materials make it very attractive. At the time of design, the goal was to make its interior frictional sounds minimal, more durable and sportier. Ford is currently leading the use of new materials in the interior. Mercury Mariner2005, which is expected to be available this fall, uses a soft, comfortable fur. The $140,000 500-horse Ford GT used Azdel SuperLite for automotive interiors for the first time. It is a compound of glass fiber and many other substances. It was formerly only used for roofs. U.S. Transport Research Institute said that at present, car users spend four times as much time on commuting traffic in cars as they did in 1982. As a result, car manufacturers and their designers have raised the importance of car interiors. The same height as the external environment. The time and money they spend on interior design while car designing is gradually increasing. (Hu Qiping) Interior work is no longer a forgotten corner Today, even the most subtle flaws in car interiors can be a failure for the whole car. If the car buyer finds that the dashboard is too bright or the plastic panel used feels too cheap, it will take a leg off. Stereo radio switches are smooth even if they are touched, but if they make a loud "click" when they spin, they will also suffer. Daimler-Chrysler hired consultants to study consumer preferences for car interiors and found that most people decided to like or hate the car within 90 seconds of fastening the doorknob. Consumers' nitpicking urges automakers (especially the Big Three in Detroit) to urge their designers to make this small space as gorgeous and beautiful as possible. U.S. companies imitate Volkswagen and other companies, use computer-aided design methods to carry out certain design work, and also improve the materials selected for automotive interiors. Some companies even increase spending to decorate dashboards, seats, and other equipment in automobiles. . Ford Motor Company's new 500 sedan and Volkswagen's cars are similar in appearance, and they are well received by most car designers and corporate executives. Nicholas Scherr, Ford`s chief operating officer, said that this model does not require much investment. He pointed out that consumers think that hollow plastic buttons give a bad feeling, so Ford turned stereo radios and environmental control knobs into device control panels. When the driver presses the button, there is no sense of emptiness caused by the plastic components of the mold. Scherer said that buttons do indeed feel more solid, and this does not cost us any cost. Interior work at General Motors is almost a corner forgotten by the product development department and this has only changed in recent years. According to company vice chairman Robert Lutz, when the budget for development departments such as body design, engines or transmissions exceeds the standard, the company will usually compress the expenses of the interior decoration department to obtain funds. Today, on the one hand, he requires all other departments to tighten the budget; on the other hand, he strives to maintain the integrity of the interior design department's budget. General Motors even added development funds to each car to improve interior levels. Lutz said: "The interior department is no longer a fund-backed bank for over-expensive departments."

China's standard parts market is very large, with potential research and development capabilities and mass production capabilities. China's rapid development of fasteners must establish an overall technology platform, and not only a single scattered technical innovation. Today's global anti-dumping measures against Chinese fasteners are higher than a wave, which is not conducive to the development of China's fastener market. A fastener company wants to maintain its continuous core competitiveness, largely due to product innovation. Product innovation includes three aspects: improvement of existing products, replacement of products, and complete new products. These are fundamental to the rapid development of enterprises and high profits. In order to respond to the development of domestic and foreign markets and respond to the country`s need to increase green energy construction, Zhejiang New Oriental has been frequently involved in high-end product development in recent years. In March 2008, it successfully developed and put into operation various models suitable for railway systems. Pull rivets and bolts, and on this basis, developed and produced pull rivets for other industries. At the same time, the company also invested in and produced fastener connection products suitable for wind turbine systems, and exported to Sweden, Australia and other countries. The products were widely praised by customers. If standard parts companies do not make product transitions or take high-end routes, the next competition will become increasingly fierce. In addition, how to recruit people and how to use them may be the biggest problem faced by the current fastener companies. What enterprises must do now is to do a good job of enterprise management, and think of ways to recruit people who are lacking. The people arrived to let the existing personnel stabilize in the company. Zhejiang New Oriental Fastener Co., Ltd. will spend 120 million yuan to develop standard parts for automobiles, including standard parts such as automobile engines and cylinder bolts. In addition, Haiyan County Bureau of Quality Supervision National Standard Product Quality Supervision and Inspection Center and research and development service team also set up a special technical team to help Zhejiang New Oriental Car Standard Parts project development.

consumers consider when choosing a new car. It ranks ahead of the vehicle's exterior design, second only to the reliability and durability of the car. Therefore, as the trend toward homogeneity in the appearance of sports cars and fashions has become more and more serious, the competition in automobile design has already fought in the contest of interior design. However, with the energy crisis and environmental protection demands, the requirements for automotive interiors have long been not only comfortable and beautiful, but also need to be safe, environmentally friendly, and lightweight. This is also the trend of automotive interiors in the future. On October 17-18, 2013, the 3rd China Automotive Interior Decoration Industry Development Forum was held in Shanghai. The forum will focus on the automotive interior design, the use of environmentally friendly materials and lightweight design and VOC standard formulation, implementation and solution solutions, etc., to explore new materials, new processes, and new technologies in the automotive interior industry. Look forward to your attention and participation. Responsive to the trend of lightweight material design has particular emphasis on automotive interior (AutomotiveInterior) mainly refers to the automotive interior modifications used in automotive products, involving all aspects of the interior of the car, such as car sunscreen, car handshake sets, car mats, car mats, Cushions and other automotive interior products. Under the tide of lighter weight in the entire automotive industry, automotive interiors are no exception. At present, the lightweight requirements for automotive interiors are mainly focused on their design and materials. It is reported that automotive interiors account for approximately 130-150 kg of the total weight of the vehicle, so efforts are made to reduce weight in the interior, which can greatly promote the lightweighting of the vehicle. By combining thin-walled storage, resin additives, and composite materials, the weight of various parts can be reduced by 5%-50%. Combining plastics with complementary materials not only significantly reduces vehicle weight, but also improves functionality. Concerned about the quality of air in the car The use of environmentally friendly safety materials Nowadays, topics arising from hazy weather are common, and the problem of air quality in cars has also become the focus of attention of car owners. The attention of the Chinese people to the air quality in the car is not enough, mainly because the color of the interior looks good, the model is beautiful or the workmanship is fine. Whether the material is environmentally friendly or the toxic components contained in the air in the vehicle is not well understood, this will lead to the impact of the air inside the vehicle on the health of passengers. A few days ago, the relevant departments of the state conducted inspections of the air quality of cars in 100 cars and found that 46% had different levels of pollution. With the development of private cars, air pollution in automobiles has become a common concern in society. It is understood that in the measured 100 vehicles, the use period is within 3 years, mainly Mercedes-Benz, Audi A6, Buick Excelle, Nissan, Santana and other brands.

The problem of air quality in the car has been increasingly concerned by the owners, but the degree of attention that the Chinese people attach to the air quality in the car is not enough. The main reason is that the color of the interior looks good, the model is beautiful or the workmanship is fine. Whether the material is environmentally friendly or the toxic components contained in the air in the vehicle is not well understood, this will lead to the impact of the air inside the vehicle on the health of passengers. This article will provide an overview of the current environmental materials and technologies used by some companies. Toyota RAV4 interior uses Softex leather material Natural animal leather is often used in interior materials for luxury cars, but its use in automobiles has been limited due to its high cost and opposition from the Animal Protection Society. At present, Toyota RAV4 and Prius V use Softex's new artificial leather, and its good cooling performance is used for the surface material of car seats. Compared with the leather material, the perforation or the suture process is very similar even on the touch. Except that this material cannot be used in parts that require large areas of foaming and granulation, other parts can be used instead of leather materials. Softex is a thermoplastic polyurethane that features high air permeability and high heat dissipation. The reason why it has good heat dissipation is that this kind of material can reflect infrared rays in the air, which is its inherent property and has not been surface treated. In the test, Softex material is 10°C cooler than the surface temperature of other materials at the same ambient temperature. Softex materials of different colors have slight differences in thermal properties, but even dark materials with strong heat absorption properties have better heat dissipation than other artificial leather materials. Fabrics and vinyl materials are still the most commonly used basic seat materials, especially on non-luxury vehicles. On the other hand, the vinyl material adheres to the seat back when the passenger sweats under hot and humid weather conditions. This is because vinyl is a nonporous material and it does not "breathe." In addition, vinyl materials will dry out when exposed to sunlight, and even leather materials that are exposed to sunlight for a long time will undergo subtle cracking, especially at pillow cushions. Most of the newer artificial leathers have "breathing" function to a certain extent, but their degree is far from that of the dermis. However, Softex artificial leather material has a moisture absorption rate that is 15% slower than natural leather but releases faster, which makes the passenger's back feel more comfortable. Although Softex materials release moisture from vinyl materials at a very fast rate, unlike vinyl materials, the former does not dry out due to sun exposure. In addition, Softrex material performs better than natural leather in fatigue, wear, and scratch testing of welds compared to natural leather materials. In addition, Softex material passed Toyota's durability test. In terms of tensile strength, Softex materials are slightly inferior to natural leather and may be limited in surface trimming and sewing patterns. In absorbing dust particles, Softex is the same as other artificial leathers and is more convenient to clean than natural leather. Toray Develops Automotive Interior Components Using Plant Fibers Toray recently developed automotive interior parts made of PLA (polylactic acid) fiber "ECODEAR", a plant-derived material, and started production first in the world. ECODEAR is a fiber made from corn. Polylactic acid is eventually decomposed into biodegradable fibers of carbon dioxide and water in a natural environment such as soil, and the calorie content is also low. The company supplied the parts to Toyota's new "Raum" spare tire covers and carpets, which were released on May 12. The spare tire cover uses a hard plate made of a uniform blend of natural fibers, Kenaf, in a PLA fiber, and is subjected to a hot-pressing treatment, which is a 100% plant-derived product. "In the future, we will add a product line of PLA fiber products for other automotive interior parts such as doors, rims, seats, ceiling materials, and Line Mat, etc. to the development of automotive-related components that need to reduce the burden on the environment." HEXPOL Develops Dryflex AM Thermoplastic Car Mat Materials HEXPOL's Elasto Business Unit has recently developed a series of thermoplastic elastomers (TPES) materials that are mainly used in car mats. Dryflex AM is based on elastomer (SBS) and Thermoplastic Elastomer (SEBS). It combines the wear resistance of rubber with the processability of plastics. It uses the Shore hardness measurement method to push standard presses into standard under standard conditions. The surface of the specimen was examined for its penetration depth to measure the hardness of the specimen. The result was a Shore A hardness of 50-75. Dryflex AM's range of applications includes automotive floor mats, coin pads, and interior materials. Car mat materials need to have high abrasion resistance and scratch resistance, in addition to good slip resistance, especially in wet environments. Dryflex AM has a high coefficient of friction on the surface to meet the anti-slip requirements. With the fuel efficiency and carbon emissions regulations established by governments around the world, automakers are looking for ways to further reduce vehicle weight. Thermoplastic elastomer material car mats are much lighter than conventional car mat materials. In addition, unlike other footbed materials, Dryflex AM material contains only minimal irritating odors, does not require vulcanization, and the material can be 100% recycled. These qualities simplify production costs and increase efficiency. Henkel Introduces New Silicone Conductive Adhesives for Automotive Electronics to Improve Temperature and Shock Resistance As the structure and working environment of automotive electrical systems become increasingly complex, the performance of related materials must also be correspondingly improved. Automotive sensor materials need to have a stronger shock resistance and temperature resistance. Henkel has recently developed a new silicone conductive adhesive (ECA) that can handle complex and harsh system environments. ICP 4000 series conductive adhesive can withstand 200 °C high temperature, in addition can withstand strong vibration. Conductive adhesive is a kind of adhesive that has certain conductive properties after curing or drying. It is usually composed of matrix resin and conductive filler, that is, conductive particles. Through the bonding of matrix resin, the conductive particles are combined together to form the conductive. Passages to achieve the conductive connection of the adhered material. Since the base resin of the conductive adhesive is an adhesive, it is possible to select an appropriate curing temperature for bonding, and at the same time, due to the miniaturization, miniaturization of electronic components, and the rapid development of high-density and high-integration of printed circuit boards, The conductive paste can be made into a paste to achieve high line resolution. Conventional conductive adhesives use epoxy materials for specific sensors. As technology advances, there are more and more sources of heat and vibration in electrical systems, and traditional materials can no longer meet these requirements. ICP 4000 Silicone Conductive Adhesive After 3,000 hours of testing at a temperature of 175°C, humidity of 85%, and 3000 thermal shocks of -40°C to 175°C, its performance in single cycle or long-term operation All are good. All types of automotive electronics manufacturers have different production and application requirements. The resistance, adhesion, thermal conductivity, and flexibility of ICP4000 conductive adhesives in a high-temperature, high-vibration environment can meet normal work requirements. The conductive filler of the conductive paste is filled with silver, and the matrix resin is a thermally curable silicone resin. It has better flexibility than traditional epoxy materials and can automatically compensate for mismatches in thermal expansion coefficients, so it can still operate normally under extreme high vibration conditions. In addition, the stimulating gas and residual colloids released during the curing process of the ICP4000 conductive adhesive are very small and will not affect the normal operation of the surrounding sensors. Kumho Ritz-CarbonTM Ultra-Low VOC Material for Automotive Interiors Ensures that the non-compliance of air quality in the interior of fresh air in cars is largely due to the failure of interior materials, and Kumho Japan The development of an ultra-low VOC material, VOC, in vehicles, has been developed. It can not only meet the performance requirements of weather resistance, heat resistance, and impact resistance of automotive interiors, but also effectively control organic The formation and precipitation of volatiles, the biggest bright spot is ultra-low sporadic. Kumho Reli is backed by the powerful polymerization technology background of Kumho Petrochemical and Nissho Petrochemical Co., Ltd., the parent company of Sino-Korea, effectively reducing the precipitation of residual monomers and low-molecular-weight oligomers during the polymerization of raw materials and relying on more than 10 years of modification experience. , The international R&D team integrated with polymerization, reactive extrusion and equipment technology has set up a special R&D team with a total investment of more than 15 million yuan. It took 3 years and successfully created the world-leading PSS technology through polymerization, extraction, and post-processing. Purification and other complex links effectively reduce the VOC content in the vehicle. According to the data from the third-party test report, the sporadic performance of plastic-clear TMABS can reach the level of TVOC<18μgC/g, and the sporadicity of plastic-degradable TMPC/ABS can reach the level of TVOC<15μgC/g, compared with the current market. The spoilage of mainstream interior materials is reduced by 60%, which is far below the control standards of the OEMs, and is far lower than the current tightest control standards for TVOC < 30μgC/g of Volvo Cars. The ultra-low VOC plastic nectar TM series really improves the air quality in the car from the source, giving consumers a healthy and safe driving environment. Adhesive selection In addition to materials, the choice of material adhesives also plays a crucial role in the quality of air in the vehicle. Most automotive interiors use artificial leather, polyurethane foam, plastic wallpaper, latex sponges, artificial carpets, cloth, velvet, and wood to increase the interior look. For example, ceilings, carpets, door panels, dashboards, etc. At present, most automotive interiors in China still use flammable, toxic, and environmentally friendly solvent-based adhesives, such as neoprene adhesives. Solvent-based adhesives not only cause serious waste of resources, cause serious environmental pollution, but also pose a great threat to the health of construction workers. Cars decorated with solvent-based adhesives release solvents slowly over a long period of time, causing injury to drivers and drivers and affecting the quality of automobiles. Water-based adhesives, because they use water as a solvent and do not contain toxic solvents, can even make volatile organics almost zero. Therefore, in the automotive industry in recent years, water-based adhesives are replacing conventional solvent-based adhesives and are starting to be used in automotive interiors and are growing rapidly. At present, the proportion of car roof lining water-based adhesives in the world has exceeded 1/3. Taking Japanese cars as an example, almost all automotive interior plastics are now water-based. Future annual growth of water-based polyurethane adhesives is estimated to remain at 8%-10%. At present, the United States, Japan, and Western Europe are at the forefront in the development of water-based polyurethane adhesives for automotive interiors. The application and research of water-based polyurethane adhesives in China is still in its infancy. Although the research and development work is very active, but the application level is not high, there are not many manufacturers, and the varieties are single, the products are mostly low-grade products, and the performance is related to Bayer. There is still a big gap between other companies. In particular, all high-grade water-based polyurethane adhesives are all imported products, mainly from Bayer, Rohm and Haas, and DIC in Japan. The development and production of aqueous polyurethane adhesives in China's mainland are still in their infancy.

Automotive plastics have many advantages that traditional materials do not have. They are mainly characterized by light weight, good decorative appearance, various practical application functions, good physical and chemical properties, easy processing and molding, energy conservation, sustainable use, etc. aspect. This article refers to the address: http:// Engineering plastics Engineering plastics are widely used in the automotive field due to their good comprehensive mechanical properties. In this paper, polyamide (PA), polymethacrylate (PMMA), polyoxymethylene (POM), polyamide (PU) are mainly introduced. ), polycarbonate (PC). PA Polyamide, commonly known as nylon, is widely used in industrial applications. PA6, PA66 and PA610 are commonly used. PA is easy to print, easy to dye, excellent in electrical properties; resistant to chemicals and oil. The mechanical commonality is tough, both have high surface hardness, good tensile strength, good impact resistance, fatigue resistance, folding resistance and stress crack resistance. The tensile strength of PA changes with temperature and moisture absorption, so water is a plasticizer for PA. After adding glass fiber, its tensile and compressive strength can be increased by about 2 times, and the temperature resistance is also improved. PA itself The wear resistance is very high, so it can work without lubrication. The disadvantages of PA are poor acid resistance, poor light resistance, and poor stain resistance. Due to the influence of thermal expansion and water absorption, the dimensional stability of the workpiece is poor, and the shrinkage rate is 1-2%. It is necessary to pay attention to the dimensional change of moisture absorption after molding. The water absorption rate is 100%, and it can absorb 8% when it is saturated with moisture absorption. The suitable wall thickness is 2 to 3.5 mm. Injection molding performance: PA has strong water absorption and strong water absorption due to the presence of amide group. Therefore, it should be fully dried during injection molding, generally drying at 120 ° C for 3-4 hours; PA viscosity is small, flow speed is fast, to prevent shot If the mouth is flowing, a self-locking nozzle or a nylon-specific nozzle should be used. At the same time, pay attention to the accuracy of the mold. Applications: PA is mainly used in the automotive field to manufacture hoses (brake hoses, fuel pipes), combustion oil filters, air filters, oil filters, water pump housings, water pump impellers, fans, brake fluid tanks, power Steering tank, white leaf window, headlight shell, seat belt. PMMA Polymethacrylate, commonly known as plexiglass, is resistant to outdoor aging, has excellent light transmission, and does not affect its transparency. It can still pass 92% of sunlight after 240 hours of accelerated aging of light, outdoor There are still 89% in the decade and 78.5% in the ultraviolet. High mechanical strength, certain cold resistance, corrosion resistance, good insulation performance, stable size, easy to form, brittle, easy to melt in organic solvents, insufficient surface hardness, easy to scratch and fluff. Suitable plastic products: transparent structural parts with a certain strength requirement. Injection performance: PMMA has a moisture absorption rate of 0.3%. It must be dried before injection. It is usually dried at 80 °C for 2 to 4 hours. At injection temperature, the melt temperature is 240 to 270 °C, and the mold temperature is controlled at 35 to 70 °C. PMMA is widely used in automotive lighting signs, door glass and lamp glass covers due to its good light transmission properties. POM POM, commonly known as plastic steel, tensile strength, impact toughness, rigidity and fatigue strength, high creep resistance, good dimensional stability, low water absorption, small friction, excellent friction and wear resistance, high temperature and The water is still very rigid and has the same chemical resistance as PA, but it is cheaper, resistant to repeated twisting and has outstanding resilience. It can be used for a long time between -40 degrees Celsius and 100 degrees Celsius. The shortcomings of POM are: it is susceptible to strong acid corrosion, high temperature resistance and poor thermal stability. Shrinkage rate 2-3.5% Suitable wall thickness: 1.5-2.5mm. Injection molding performance: POM has obvious melting point, melting at 175 °C, decomposition at 240 °C, general processing temperature is 190 °C ~ 220 °C, its processing range is very narrow; POM does not absorb water, generally does not need to be dried during injection molding However, the product with high quality requirements can be dried at 60 ° C for 1 to 2 hours; the temperature should not be too high, otherwise the dyed product will be discolored; its acid resistance is poor, and it can not be dyed with acid dye. Applications: POM uses and manufactures instrument panel glove box accessories, various valves (drain valves, air conditioner valves, etc.), various impellers (water pump impellers, heater blades, oil pump wheels, etc.), various electrical switches And small gears on the electrical instrument, various handles and door pins. PC Polycarbonate, with outstanding impact toughness and creep resistance, good heat resistance, good cold resistance, embrittlement temperature of -100 ° C, bending strength equivalent to nylon, and high elongation and elasticity Modulus, but fatigue strength is less than nylon 66. Low water absorption, low shrinkage and good dimensional stability. The wear resistance is comparable to that of nylon and has a certain corrosion resistance, but the molding conditions are high. Good weather resistance, long-term application under high temperature and high load conditions, but can not be used under wet temperature, poor solvent resistance, stress cracking, and poor fatigue strength. The shrinkage is 0.5-0.7%, and the suitable wall thickness is 2-3.5 mm. The addition of PC to glass fiber can improve its shrinkage, mechanical strength and temperature resistance. The long-term use of steel at 100 °C will increase, and the internal stress can be improved by annealing. Injection performance: PC has obvious melting point, melt at 220 ° C, decompose at 350 ° C, the general processing temperature is 250 ° C ~ 320 ° C; it absorbs water, a small amount of water can cause it to decompose at high temperatures, must be baked during injection molding Dry, drying temperature can be dried at 120 °C for 4 to 5 hours; PC material has a high melt viscosity, which requires a large pressure during injection; PC can be used to improve the mold with mold temperature if the conditions permit. Temperature to reduce the residual stress of the product; PC shrinkage rate is independent of the processing conditions and the wall thickness of the product, and its longitudinal and transverse shrinkage ratio is relatively close, so it can be processed into a highly accurate product; its shrinkage rate is 0.5%. . The main synthetic PC-abs: PC-ABS is a blending material of PC and ABS, which is usually supplied in the form of pellets after blending. If only two materials are simply mixed, direct injection molding, the effect is very poor, there will be stratification; PC has the advantage of being rigid and tough, the disadvantage is stress cracking, high viscosity; ABS has the advantage of good fluidity, but the surface The hardness is low; the blended material PC-ABS retains the advantages of both; PC-ABS has high surface hardness, high rigidity and toughness, and high resistance to stress cracking; its mechanical properties Between the two. Scope of application: PC is mainly used in the automotive field to manufacture lampshades, left and right wheel cover guards, instrument baffle body (PC+ABS), left and right wind frame cover, middle wind frame cover (PC+ABS), rear bumper cushion. PU Polyurethane is generally classified into a rigid polyurethane and a flexible polyurethane depending on the polymerization product. The rigid polyurethane has high strength, good toughness, good heat insulation, good waterproof effect, simple molding process and high production efficiency; flexible polyurethane has good elasticity, good sound absorption effect, aging resistance and chemical resistance, etc. The mechanical properties far exceed the materials such as pvc. The polymerization of polyurethane is very convenient, not only can be carried out under normal temperature and normal pressure conditions, but also can be directly foamed or sprayed, repaired, etc. after on-site polymerization. Polyurethane foam is widely used in automotive interiors and vibration absorbing parts, such as coating materials, polyurethane rigid plastic sheets, polyurethane elastomers, seat soft foam materials, decorative parts, sofa leather, roof accessories; It is a variety of soft and rigid polyurethane foam materials, it has vibration isolation, sound insulation, noise reduction, thermal insulation; PU can also be made into automotive polyurethane coatings, adhesives, sealants and so on. The PU on the car represents the instrument panel, rear view mirror, bumper, seat cushion, headrest, steering wheel, instrument panel anti-vibration pad, pillar trim, front roof lining, window frame, ceiling and side top Frame decoration, door lining, sun visor, rear top frame decoration, etc.

The use of non-woven fabrics as automotive interior trim materials is a current international development trend. Because of its low cost, high adaptability, high strength, and light weight, it is widely used in the automotive industry. However, many automotive nonwovens require water repellent finishing, such as automotive carpets. This type of carpet is generally molded by molding and consists of three to four layers of different materials. The outermost surface layer is made of water-repellent, oil-repellent, flame-retardant, and antistatic treated carpets. The roof, door trim, and guardrail in the car Seals for windows and doors generally have to undergo water and oil repellent finishing. However, the conventional water-repellent non-woven fabrics circulated on the market today are obtained by applying a water-repellent finishing agent in the finishing stage. Although the water repellent effect has been improved, the stability of the water-repellent non-woven fabric has been unsatisfactory. In this case, researchers from the material speciality of the Technical University of Lower Rhine in Germany proposed the [silicone water repellent finishing technology". According to the published data, it can be seen that after the silicone water-repellent finishing, the surface of the non-woven fabric is covered with a polymethylsiloxane-based emulsion-like film whose oxygen atoms are directed to the fiber surface, and the methyl group It is oriented away from the surface of the fiber. The researchers found that the proper orientation of silicone polymers on the fiber surface is a necessary condition for water repellency. In general, water repellency increases as the carbon chain grows. In addition to converging to each other, the polymethyl siloxane can also form hydrogen bonds with hydroxyl groups on the surface of the fiber, so that the hydrophobic methyl groups are densely oriented on the surface of the fiber, so that satisfactory water repellent properties are obtained, and Has a certain wash effect. The researchers pointed out that polymethyl siloxane is best kept in emulsion. Therefore, the choice of emulsifier is critical in the silicone water repellent finishing process. It has been found through verification that the temporary complex cationic emulsifier can efficiently siloxylate the polymethylsiloxane into a stable emulsion, and can also be decomposed during the finishing baking process, so that the stability and water repellency of the emulsion are better solved. The contradiction between. Silicone water repellent finishing technology is still in the laboratory stage, but the key experimental data has been relatively perfect: the optimum mixing ratio of polymethyl siloxane and emulsifier is 3:7, and the drying temperature should not be lower than 150 °C. , The best water repellent effect. It is understood that a German car production company has cooperated with the University of Lower Rhine for experimental production. In addition, recently, Mitsubishi Heavy Industries of Japan has developed a high-tech resin with a waterproof and air-permeable function. As long as the liquid material, which is called a shape memory polymer, is applied to the surface of the fabric, the fabric will not be permeable, but moisture can still be obtained. From the inside out, it is very suitable for functional clothing such as raincoats. The waterproof, air-permeable function of the shape memory polymer is similar to that of human sweat pores, and has a promising future. As an energy-saving and environmental-friendly building insulation material, foam insulation materials are widely used in insulation and heat insulation projects for roofs and exterior walls. However, if preventive measures are taken improperly, there will be potential safety hazards. Care must be taken when installing and removing, especially in the event of a disaster, rescue workers need special protection measures to protect others while helping others. Precautions during installation Foam insulation material has the characteristics of insulation, energy saving, and is widely used in many buildings. Traditional insulating materials, such as glass fiber, are also superior in thermal insulation performance by spraying foam. Foam insulation is a type of polyurethane that exhibits different properties under different conditions. For example, when a polyurethane molecule slowly expands as it heats, the phenolic spray can shrink by curing. Sprayed Polyurethane Foam (SPF) can be sprayed on a hard-to-reach place, similar to a "sandwich" structure wall. Workers can use a special spray gun to spray foam between walls or drill holes to expand the foam to seal. Polyurethane Foam Insulation Used in Construction Considerations Foam insulation is often more expensive than other types of insulation, which also makes it more expensive. It seems that the additional investment, such as increasing the water vapor barrier capability of the foam or increasing its structural stability, is not worth it. In addition, the location of the foam insulation material needs to be considered. It should not be placed in direct sunlight or exposed to high temperatures. Most foam materials cannot be exposed to high temperatures and intense temperatures for long periods of time. SPF insulation material must be specially treated prior to use. For example, certain materials must be properly heated during use. Installation in an exposed environment can cause foam insulation to emit harmful chemicals. Since many foam insulation materials use greenhouse gases as blowing agents, laws must be followed to specify thickness levels and distribution arrays. Foam sprays can also release harmful toxins, which means that workers need to fully protect themselves from harmful gases. Precautions when removing Thermal insulation foams may also cause the spread of toxins when dismantled or modified. Many foams are toxic. If buildings are dismantled with explosives or other destructive measures, these toxic substances will spread into the air, causing discomfort to workers and residents living in the surrounding areas, not to mention the effects of rising into the atmosphere. force. If the buildings are water supply sites in nearby communities, the severity of these problems will increase significantly. These toxins cause contact with the skin and cause discomfort. If you accidentally come in contact with your eyes, it may cause temporary blindness. Therefore, foams need to be carefully removed at low temperatures to ensure maximum safety. Rescue workers must carry safety equipment in case of disaster In case of unexpected danger, rescue workers need to know how to protect themselves in dangerous foam devices. When a building collapses or catches fire, the smoke released by the burning foam into the air can cause people to lose consciousness or blindness, so it is necessary to carry safety equipment and breathing apparatus. If bubbles ignite, they will not only release toxic fumes but also accelerate the rate of burning. If rescue workers are aware of these possible problems, they can better plan their actions at the rescue site. China is one of the fastest growing countries in the construction industry in the world. By 2014, China's thermal insulation building materials will account for 29% of the global market. At present, China is the country with the most demand for insulation materials in the world. The energy-saving building first of all has its premise of safety. Without safety, the building loses its significance. Only when the use of flammable, flammable, and dangerous insulation materials on the building walls is eliminated, major fire accidents can be suppressed at the source. Foam insulation materials are used as wall insulation materials and should be widely used while preventing fires from occurring. . Perhaps in the near future, a new generation of insulating foam insulation will certainly become the main force of building energy conservation. Foamed wood-plastic composites are based on wood/plastic composites with appropriate amounts of foaming agents, nucleating agents, activators, etc. to reduce the density, improve the impact strength, toughness, fatigue cycle, and thermal stability. . details as follows: 1) The purpose of the foaming agent is to reduce the mass of the composite material (reducing the density), making the application of the composite material more extensive. The foaming agent is decomposed by heating to generate gas, which is incorporated into the composite material and exists in the form of microporous bubbles. Foamed plastic is a bubble composed of bubbles. This experiment mainly uses chemical foaming, and the foaming agent used is AC. 2) Nucleating agent is a new functional additive. The nanoparticles not only act as nucleation sites for the blowing agent, but also can refine the high polymer grains and increase the toughness of the composite. The nucleating agent used in this experiment is ultra-fine talcum powder. 3) Activator is a reagent that promotes foaming of AC blowing agents at lower temperatures. The leading professional exhibition of wood-plastic composite materials industry in China, Shanghai International Wood-plastic Composite Exhibition, will be opened in Shanghai Exhibition Center tomorrow. It is reported that the scale of this exhibition is 3,000 square meters. Dozens of high-quality wood-plastic composite suppliers will display the latest and best wood-plastic products for domestic garden landscape and architectural designers. At the same time, it will also demonstrate the application trend of wood-plastic composite materials through actual case demonstrations at home and abroad. In addition, the Ninth Forum of Wood-plastics International Summit (Shanghai), organized by the wood-plastic special committee, will bring together top-level business people and experts from China, Japan and Germany to discuss the construction of wood-plastic composite materials. Applications such as home and garden landscapes. Leading wood-plastic companies from Japan, such as Mitsubishi Rayon Co., Ltd. and Reifenhausen of Germany, will appear at the 2013 Shanghai WPC Exhibition, sharing top-level wood-plastic products and application cases, creating a mutual understanding and communication with domestic designers. Opportunity.

Last week's market review: last week, the auto vehicle segment rose 0.95%, auto parts rose 2.38%, the Shanghai Composite Index rose 0.22%, the auto vehicle outperformed the broader market by 0.72%, auto parts outperformed the market by 2.16%. The fine-tuning of policies facilitates the improvement of car demand. After the weekend, the central government reduced the deposit reserve ratio. The fine-tuning of policies will benefit the improvement of auto demand. It is expected that the year-on-year growth of auto sales in January will be the low point in the first half of the year. In the automotive sub-sector, the sales growth of joint-venture brands and car companies is still far better than the industry average; if the 12-year new bus implementation is implemented, it will benefit the improvement of self-owned brand demand; the 11-year decline in micro-customer sales growth in January 2012 For the first time, passenger vehicles are better than narrow ones, and the demand for mini-vehicles is also improving. In reality, the demand for mini-vehicle terminals in some auto companies is much better than the growth rate of wholesale numbers. We believe that the main reasons are that the auto companies' own inventories return to normal levels; the second is that the demand effects of the 2009 and 10 year overdrafts in 2009 that will result in an 11-year overdraft will significantly decrease in 12 years; we believe that the new policies for the buses The effect and follow-up sustainability of mini vehicle demand are worth investors' attention. Industry point of view: Maintain the continued optimism of Dazhong Coach Leading Company and high-quality passenger car companies, and pay attention to the improvement of micro-customer demand from some auto companies. We continue to favor the large and medium-sized bus industry and its leading companies. In January and February, the growth in total sales volume was a high-probability event. Due to the diminishing effect of exit policies on automobile stimuli, we can focus on the improvement in the follow-up demand of micro-subscribing customers; The growth rate of passenger vehicle sales is about 25%, and the policy is relaxed. Concern over whether demand for heavy trucks in March can pick up. The vehicle is still optimistic about Yutong Bus and Shanghai Automotive; spare parts are optimistic about Huayu Automobile, Zhongding shares, precision forging technology, mini cars focus on Changan Automobile, and heavy truck rebounds focus on Foton Motor.

According to the data from the Auto Group, in August, the number of auto sales was 1,322.3 thousand, which was an increase of 6.3% from the previous quarter and a year-on-year increase of 16.1%. Among them, 1,109,900 were sold by passenger cars, which represented an increase of 7.7% from the previous quarter and an increase of 18.72% year-on-year; commercial vehicle sales were 303,300, an increase of 1.83% compared with the previous quarter and an increase of 8.24% year-on-year. From January to August, the sales of motor vehicles reached 11.5826 million, an increase of 39.0% year-on-year; among them, sales of passenger cars were 8,866.1 thousand, an increase of 39.5% year-on-year; sales of commercial vehicles were 2,869,500, an increase of 37.6% year-on-year. In August, the sales data of China National Automobile Research Institute was close to that of the Auto Industry Association. The production and sales of self-owned brands and Japanese and Korean cars, which had serious stocks, began to increase. This shows that the current stocks are basically at a reasonable level, and automobile production and sales have entered a normal track. Due to the base problem, the growth rate of automobile production and sales may fluctuate significantly within the next year, but the absolute value of production and sales will return to normal growth. The market has already fully reflected the warming of sales data. Under the assumption that automobile production and sales return to normal track, the investment in the automotive industry needs to grasp the subtle changes in the industry. With the continuous improvement of energy-saving subsidies and emission standards, the advantages of joint ventures It will be further consolidated, and manufacturers who are committed to emissions equipment will benefit significantly. The recommended combination is Weifu Hi-Tech, Jiangling Auto, Shanghai Auto, and Huayu Auto.

Jinan Languang Electromechanical has successfully developed the first domestic automotive interior parts atomization tester, providing scientific and efficient testing tools for automotive industry manufacturers to choose the ideal interior materials. Under the action of high temperature, the volatile components in the automotive plastic interior materials evaporate and condense on the windshield or the window, which may cause poor line of sight and affect driving safety. Jinan Languang's new FT-F1 atomization tester is designed according to the German DIN 75201 standard. The high-temperature acceleration is used to complete the evaporation process. The simulated car is placed under sunlight, so that a certain material can be quantitatively analyzed. The degree of atomization of glass and windows. At the same time, the test results can also help to determine the amount of toxic and harmful substances in the sample; and can help to determine the degree of influence of the atomization of the xenon headlamps on the illumination.

The instrument panel is a car interior component that is subjected to the strongest sunlight exposure and is a representative component for studying the aging resistance of automotive interior parts. According to the test standard of the aging test box for automotive interior parts, the parameters of the artificial accelerated aging test for several commonly used automotive interior parts are as follows: Method 1: Exposure procedure: full illumination Inner/outer filter: borosilicate glass/soda lime glass Irradiance: 1.25W/m2 (420nm) Black mark temperature: 100 ° C Relative humidity: 50% Method 2: Exposure procedure: full illumination Inner/outer filter: borosilicate glass/soda lime glass Irradiance: 1.25W/m2 (420nm) Black mark temperature: 100 ° C Relative humidity: 20% Method 3: Exposure procedure: full illumination Inner/outer filter: quartz glass/borosilicate glass Irradiance: 1.25W/m2 (420nm) Black mark temperature: 89 ° C Relative humidity: 50% Dark section: 1h Blackboard temperature: 38 ° C Relative humidity: 95% The xenon lamp aging test chamber can be used to select new materials, improve existing materials, or evaluate changes in durability after material composition changes. It can simulate the changes in materials exposed to sunlight under different environmental conditions.
