Recently, China Polyurethane Industry Association and Chongqing Changshou Economic Development Zone jointly sponsored by the 2017 polyurethane material automotive applications Conference held in Chongqing.Experts pointed out that China's current automotive polyurethane should comply with the downstream industry trends, expand market applications, to play a regional aggregation Development advantages, innovation and development of low-VOC (volatile organic compounds), high flame retardancy, high comfort and other products.
Fu Xiangsheng, vice president of China Petroleum and Chemical Industry Federation, said that as a big country of polyurethane production, many kinds of raw materials for polyurethane in our country are advanced in technology and lead in output, but there is still a problem of low-end excess and high-end lack of automobiles in general.Automobile is an important downstream market for polyurethane. At present, 60% of the automotive foam materials are polyurethane materials, and the polyurethane industry should seize the development trend of lightweight, high-end, high comfort and safety and environmental protection in the automotive industry, enhance technological innovation and achieve transformation and upgrading.
'China's auto production and sales for the first time in the world for the first time in 8 years, the future China's auto industry will continue to show a better development trend, while automotive interior materials with polyurethane market demand will also continue to grow exponentially .As consumers car interior Grade, function, environmental protection and other requirements continue to improve, eco-functional polyurethane products will be the development of automotive materials focus, facing huge market opportunities. 'China Polyurethane Association Secretary-General Lu will tell reporters.
Li Guangyao, a senior engineer at CNHTC (Hong Kong) Co., Ltd., said that environmental protection is the innovation direction of polyurethane materials. The VOCs produced by polyurethane foam, adhesive, paint and synthetic leather in automobiles are the main factors that affect the air quality inside the vehicle.
To this end, experts said that the development of automotive polyurethane material mainly in six areas.First, the functional composite of a variety of materials has gradually become one of the important technical means to improve the performance of automotive non-metallic parts, such as TPU and PP, PVC, PC, PA and other plastic, TPU and rubber to form a composite material with excellent performance-price ratio, which can play a significant role in the automobile industry. Second, the development of polyurethane foam and products is becoming more and more lightweight, multi-hardness, low odor, Aging, storage stability and more environmentally friendly direction; Third, the material formulation, molding process needs to be further optimized to meet the requirements of national laws, regulations and standards; Fourth, the material interface is compatible with the reaction heat, the curing speed and Stability is worth attention; Fifth, the new material test evaluation method to be material manufacturers and auto manufacturers uniform standards and birth of the corresponding market demand; Sixth, with the continuous improvement of polyurethane industry technology, eco-functional polyurethane products There will be greater demand for growth, especially the demand for ultra-fine fiber PU leather will be more and more.
'Automobile manufacturers have long been focusing on in-car comfort Polyurethane soft molded foam, as the key material in the construction of a car seat, has played a major role in providing comfort to passengers, Automotive interior environment, especially the smell of the car, atomization has been classified as a new standard to judge comfort or not. "Zhang Wei, deputy general manager of Jiangsu Meistech Co., Ltd. said the company developed a new type of silicone Surfactants AK-7715LF and AK-7716LF are mainly suitable for MDI or modified MDI system with content of 50% or more. They have good opening function, can bring regular surface structure to foam, Of particular importance is the environmentally friendly nature of low VOC and low FOG.
In addition, China's auto industry on the adhesive and sealant in total demand of 10 million tons, of which polyurethane plastic occupy a considerable proportion.Shanghai Jintang Plastic Technology Co., Ltd. General Manager Zhan Zhongxian that the trend of automotive development is lightweight, non-metallic Materials and composite metal materials will be widely used, environmentally friendly adhesive research and development, production will become the mainstream. Water-soluble adhesives, solvent-free adhesives, hot melt adhesives will have good prospects for development.
Lu will be told reporters that China Polyurethane Industry Association to develop the industry's '13th Five-Year' industrial development plan put forward clearly that the future development of polyurethane industry is the most obvious trend of industrialization, base, speed up the process of integration, lengthen the industrial chain, to participate International competition, and the construction of a number of Lingang polyurethane industrial base. Car polyurethane materials should be in line with this trend, give play to the advantage of the industrial chain, to achieve agglomeration development.According to reports, China's Jilin, Cangzhou, Chongqing and other places, has basically formed a car R & D, production and application of polyurethane industrial chain.
