This project belongs to the field of polymer matrix composite materials. It is included in the 863 research projects of the Ministry of Science and Technology of the People's Republic of China, Shanghai City Major Science and Technology Research, Shanghai City Nanoscale Project, Shanghai City Base Construction Project, Guangdong Province, Provincial Ministry of Industry and Research Major Projects, etc., focusing on the development of structure-Functional integrated high-quality polymer composites to meet the urgent needs of new polymer materials that are light, high-strength, safe and environmentally friendly in the increasingly developing industrial fields such as automobiles and home appliances.
This project focuses on breaking through a series of key technologies for high-quality polymer composite materials for automobiles and electrical appliances, and has achieved many important core technology inventions, including: through the development of multi-scale composite of layered inorganic fillers and dispersion of masterbatch, polymer alloy compatibilization and rigid-toughness balance, polyester crystallization control and resource utilization, environmental protection and flame retardant and other innovative technologies to prepare a variety of engineering plastics with excellent comprehensive properties for automobiles and home appliances and achieve large-scale production and application of products. The comprehensive properties of the polymer composite products developed in this project are leading in China, reaching or even better than the advanced level of similar foreign products. Among them, the lightweight and high-strength nanocomposite polypropylene material for automobiles has excellent characteristics such as scratch resistance, light resistance, low odor, and low emission that must be possessed by high-quality automotive interior trim materials. At the same time, it has excellent low-temperature impact resistance. It can fully meet the requirements for seamless instrument panel airbags to open smoothly without producing hard fragments that may hurt people under extreme low temperatures (-30℃) and various harsh conditions; Long glass fiber reinforced polypropylene materials have ultra-high toughness and good appearance, and are cost-effective. They have successfully realized the matching of high-end models such as the BMW 5 Series, becoming BMW Motors 'first domestic polymer composite material to replace imported products. The localization of high-performance polymer composites is of great significance; the comprehensive performance and performance of PC/ABS engineering plastics with high rigidity, low emission, and high weatherability are better than similar products of GE, Bayer and other companies. They are cost-effective and have strong market competitiveness; Laser-marked ABS alloy materials have better performance than similar products of Japan's DAICEL and other companies, and have won the title of National Key New Products; flame-retardant reinforced nylon products have excellent mechanical properties, heat resistance and flame retardant properties, and have been successfully used in a variety of washing machines and other household appliances. Structural parts products.
This project has achieved many innovative results in the development of high-quality polymer composite materials for automobiles and electrical appliances, and has applied for 32 China invention patents, including 17 authorizations. After testing by authoritative national departments, scientific and technological novelty searches, user reports and expert acceptance, it is pointed out that the project has generally reached the international advanced level. A variety of polymer composite materials developed by the project have achieved large-scale production and promotion and application in many enterprises in Shanghai, Guangdong and other places. In the past three years, the company has added more than 1.13 billion yuan in new output value and more than 270 million yuan in new profits., and increased tax revenue exceeds 43 million yuan. The polymer composite materials produced have been used in automobile parts produced by BMW, Shanghai General Motors, Shanghai Volkswagen and other companies, as well as in electrical and electronic products of well-known companies such as Haier and Midea.
This project focuses on breakthroughs in core technologies of various polymer composite materials and their application in industrial production, effectively improving the overall quality of domestically produced related materials, and plays an important role in promoting product environmental protection, safety, added value and market competitiveness., Greatly promoted technological progress in related industries.
