Global consumption of rubber plastic products 30 million tons a year

Annual consumption of rubber products reach 30 million tons, the rubber gross industrial output value of more than one trillion yuan. Rubber is widely used in automobile tires, aircraft tires, conveyor belt, tubing, sealing ring, gloves, medical materials, and other fields, is other polymer materials can not be replaced. At present, China is still not fully independent intellectual property rights in the field of rubber, severely limits the development of China synthetic rubber. The consumption of synthetic rubber in China each year in 8 million tons, and production is insufficient, still rely heavily on foreign imports. Beijing university of chemical industry development of China's original rubber varieties in order to realize the sustainable development of rubber industry, the development of China's original rubber varieties, elastomer center of Beijing university of chemical industry in 2008 put forward with different biological dibasic acid and glycol as the monomer, by melt polycondensation method, obtained a series of biological base polyester elastomer. The biological basis of polyester elastomer for China's original synthetic rubber varieties, and is expected to achieve zero breakthrough in synthetic rubber varieties in China; Don't rely on oil resources, the raw materials are obtained by fermentation, in line with the requirements of national environmental protection and sustainable development. Elastomer center of Beijing university of chemical industry through more than ten years of unremitting efforts, dozens of bio-based polyester elastomer was synthesized, and its industrialization and application development, was built in 203 a tonnage of the biological basis of polyester elastomer production line. At present the team cooperation with new material company, found out the various production process parameters of polyester elastomer, is launching a tonne bio-based polyester elastomer production line for the construction of the demonstration. Break the foreign monopoly, independent development of PVC plasticizer bio-based polyester elastomer has a strong polarity, so excellent oil resistance, can replace nitrile rubber and acrylate rubber, used in oil field of seal ring. It is understood that the price of nitrile rubber in 20000 yuan per ton, acrylate rubber price is close to 00000 yuan, and need to be imported from abroad. Biological basis of polyester in the field of oil resistant rubber materials to replace these two kinds of rubber material is feasible from the price. Every year China polyvinyl chloride, PVC) The amount of plasticizer production of more than 20 million tons, its also more than millions of tons. Existing PVC plasticizer is not environmental protection, and by foreign monopoly, be badly in need of development of China's independent of PVC plasticizer. Professor zhang liqun team of Beijing university of chemical synthesis of biological basis of polyester, non-toxic, resistant to dissolution, plasticizing effect is good, is a kind of excellent PVC plasticizer. The biological basis of polyester elastomer also have biodegradable performance, is currently the only can degradation of synthetic rubber materials. This type by changing the structure and packing material, to achieve the effective control of the degradation speed, is expected to get biological matrix controllable degradation of tires, thus from the root to eliminate tires and tire wear debris pollution to the environment.
