Development Of Automobile Industry On The Impact Of Plastics Industry
Whether domestic or foreign, cars are one of the fastest growing industries
, the industry overall economic efficiency indicators showing growth spurt. The rapid development of the automotive industry, stimulating the demand of the automobile manufacturing materials, which directly stimulate the rapid development of the plastics industry, the plastics play an increasingly important role in the automotive industry.
The smell of interior materials has caused widespread concern of consumers, the presence or absence of abnormal odor has become an important reference for the consumer to buy a car. Internationally renowned automobile have stringent odor and volatile gas testing standards for the materials used in automotive interior parts, and these standards with the upgrade of consumer demand has become more and more stringent. Plastic products have good performance, low price, colorful colors and simple process, which can undoubtedly meet the requirements of people for the car. Extensive use of plastic products in the automotive industry in order to replace expensive non-ferrous metals and alloys, can not only improve the appearance of automotive styling and design of flexibility, reducing parts processing, assembly and maintenance costs, but also can reduce the energy consumption of the car. The amount of plastic products reflect the level of development of a national auto industry, every vehicle of German averagely use about 300kg of plastic products, accounting for about 22% of the automobile material, adopted the most automotive plastic parts in the world. Average use of plastic per vehicle in Japan reached about 150kg, about 12% of the total consumption of automotive materials; Even a Japanese company to develop and sell new cars, in addition to seat, roof, decoration materials, instrument panel and other interior parts all use plastics to manufacture.
Currently, development trend of automotive plastic products applications by common decorative items change to structural components and functions, thus the use of plastic raw material is also extended by the ordinary plastic to the higher strength, better impact resistance of composite material or a plastic alloy. Automotive thermoplastic composite materials are the main subjects. The resin materials research focus on to continuously improving the physical and mechanical properties of the material; Material development shifted from expensive special resin to low-cost ordinary resin new varieties system; Self-reinforced resin is also a hot topic of material research and development (such as the SR-PP); the European focus on continuous laminate molding and compression molding material, while North America is the injection molding material. Research and development of nanocomposites received extensive attention, including nano-layered silica, carbon nanotubes to enhance the PA, PE, PVC, improved interface features, etc.
