APPLICATION OF POLYURETHANE FOAMING MACHINE EQUIPMENT IN THE AUTOMOTIVE INDUSTRY

According to the analysis of relevant industry personnel, the application of polyurethane foaming machine equipment in the automobile industry is an important indicator of the level of modern automobile design and manufacturing technology. According to the survey, the average plastic consumption of cars in developed countries is about 190kg/car, accounting for 13%~15% of the car’s own weight, and even mass-produced all-urethane-body sports cars; while the average plastic consumption of cars in my country is 80~100kg/car, accounting for 8% of its own weight, the application ratio is obviously low.

Among all the materials used in modern cars, polyurethane (PU) is not only the largest in the amount, but also its application range is unparalleled: from the car box to the outer parts, from soft to hard, from light to dense, to For high-strength glass fiber reinforced products, the application of polyurethane can be seen everywhere, and the investment in polyurethane foaming equipment is inevitable. The demand for the automobile industry is mainly determined by the sales volume, that is, the increase in the number of automobile license plates. Although car sales worldwide have maintained slow growth, detailed regional analysis shows that Asian car production has declined, while European and American car production has maintained a moderate growth. In the next few years, the world's automobiles will grow at a rate of 2% to 3%. The speed of Asian economic recovery determines the growth rate of automobiles, and it is generally believed that the strongest automobile market development will occur in this region. The amount of flexible foams and rigid polyurethane foam insulation foam materials in the vehicle compartment accounts for 2/3 of all the polyurethane required by the automotive industry, of which the seat back occupies a larger portion, while the amount of headrest and carpet foam lining is much less . More comfortable, safer, lighter, more comfortable and safer are the eternal requirements of the automotive industry, especially for future car compartments. It is expected that the application of polyurethane materials in automobiles will increase in the next few years. Most of the large-volume cars used by the middle class have been installed with polyurethane foam-based carpets, and suppliers have benefited a lot.

Minimizing the application of PVC in automobiles is another development trend, which will bring opportunities for the application of some new materials. Cars nowadays pay more and more attention to packaging, which means that the engine temperature is much higher than a few years ago. The weight reduction of components is a leading direction of the current research. The reduction in the amount of raw materials reduces costs on the one hand, and reduces fuel consumption on the other. Polyurethane is used in automobile interior and exterior parts and body components to make the application prospect of polyurethane encouraging. In addition to environmental issues, more comfort, more safety, fewer processes, and lower costs, the main driving force for the development of polyurethane materials is new and strict environmental regulations.

It is understood that the current international development of polyurethane foaming machine equipment for vehicles is extremely rapid, and the proportion of applications is increasing year by year. However, my country is still at a low level, with low technological content and narrow application scope. Therefore, we should speed up the research and development of polyurethane technology in automotive applications, and strive to improve the manufacturing technology level of China's automotive industry. Recently, it was learned from the 2011 China Automotive Industry Polyurethane Application Summit that lightweight, green and environmental protection, and comfort and safety have become the three major themes in the development of automotive materials in my country. Among them, automotive polyurethane products will play an important role.
