  • Detail

Development status of China's automobile plastic products industry nowadays, plastic synthetic resin, synthetic rubber and synthetic fiber, together with steel, wood and cement, constitute the four basic materials in modern society. They are one of the important new materials supporting the development of modern high technology, including information, energy, industry, agriculture Transportation, aerospace and ocean development are indispensable means of production in all important areas of the national economy, and have become indispensable means of consumption for human survival and development. Luobaihui, head of the international mold, hardware and plastic industry supplier Association, said that China's plastic industry is a "sunrise industry" integrating plastic synthetic resin, additives and additives, plastic processing machinery and molds with plastic processing as the core. The industrial scale is expanding, the product output is increasing year by year, the main economic and technical indicators are increasing by a large margin, and the whole industry is growing. It is moving forward along the road of realizing the sustainable development of the plastic industry from a big country to a powerful country

overview of the development of plastic products industry

plastic is an important material that can realize "reduction, reuse and recycling" in the development of modern economy, especially in the application of automobiles. Its processing and molding is a process of no pollution emission, low consumption and high efficiency. Most plastics can be recycled after use. It is a typical resource-saving and environment-friendly material. Luobaihui said that the plastic processing industry has maintained rapid growth with the sustained, stable and rapid development of China's economy, and has great development potential. 2.5kg of weight has been added to the national efforts to promote energy conservation and emission reduction and circular economy development policies, economic and technological innovation, accelerate the construction of new socialist countryside, and continuously promote the process of urbanization × Positive factors such as the increase of 3 + 1.25kg=8.75kg and the rise of domestic consumption have further promoted the great development of the plastic industry

2011 is the first year of China's 12th Five Year Plan. The plastic processing industry is actively exploring its internal potential and opening up the international market. At present, the demand for plastic products is still growing, especially in the field of plastic building materials, which is not weaker than that in previous years. Even under the situation of the global financial crisis, it still maintains a substantial growth

1. Sustainable development of automotive plastics

the sustainable development of automotive plastics can be reflected in the following four aspects:

energy conservation and emission reduction (automobile lightweight and plasticization)

green environmental protection

fire safety

renewable utilization

2. The application of plastics in automobiles is growing rapidly

at present, automotive plastics account for% of the total plastic consumption. The average consumption of automobile plastics in industrialized countries increased from kg in the 1990s to 152kg in 2004 (accounting for 8.3% of the vehicle weight) and 174kg in 2006 (accounting for 9.1% of the vehicle weight). Consumption of automotive plastics in Europe: 10 ~ 14%, with an average of kg/vehicle. High oil prices drive the use of more plastics, reducing the weight of the car body and improving fuel efficiency

the varieties of plastics used in modern automobiles have covered almost all fields, such as PP, PVC, ABS, PA, PC, PE, thermal, solid composite materials after the first generation of mini came out in 2001. There is a strong demand for resin market, and the demand for PVB accounts for more than 85% of its total demand

PP, the largest variety of automotive plastics, accounts for 2.5% per year It is expected that the average consumption of automobiles in developed countries will reach more than 500kg/vehicle by 2020. At present, the consumption of domestic automotive plastic PP accounts for about 40%, and the others are Pu, ABS, PVC and PE in turn

pp consumption is kg/vehicle: for example, Volkswagen VW Passat 2005, the body weight is 1429kg, including steel 52%, aluminum 13%, liquid 4%, glass 2% and plastic 14%. Among them, 73kg of polypropylene, 27kg of polyurethane, 25kg of nylon and 16K of polyethylene were used. G and abs15kg were used when checking the on-site installation at the customer's home

another example is Peugeot 2005, with a total body weight of 1210kg, including steel 60%, aluminum 7%, cast iron 6%, liquid 4%, glass 3% and plastic 13%. The consumption of polypropylene is 77kg, polyurethane is 19kg, nylon is 18kg, pet/pbt alloy is 13kg and polyethylene is 8kg

3. The effect of automotive plastics on energy conservation and environmental protection is remarkable

in recent years, automotive lightweight has become the main development direction of automotive materials. Energy conservation and environmental protection have become two major topics in the development of automotive industry, and plastics, their composites and alloys are ideal materials that can accelerate the automotive industry to achieve this goal; The biggest advantage of using plastics to make automobile parts is to reduce the weight of the automobile, reduce the cost and process, and improve some automobile performance

automobile plastic parts replace expensive non-ferrous metal and alloy parts, which can not only reduce the vehicle weight and reduce the fuel consumption and hydrocarbon emissions if we want to make the work more efficient, but also improve the power, adapt to the harsh environment and increase the safety. In addition, the plastic can be recycled, thus saving the resource consumption in the manufacturing process, and finally making more breakthroughs in both safety and cost

the application of plastics in automobiles also facilitates the humanization and diversification of automobile appearance design and the comfort and aesthetics of interior trim, and reduces the costs of component processing, assembly and maintenance. It can be seen that the plasticization of automobile parts is a major development trend of the international automobile manufacturing industry
