On February 25, we learned from the institute of petroleum and chemical industry that the "key technology for the industrialization of synthetic rubber", a national key research and development project led by the institute, has achieved initial results.
In star branched butyl/brominated butyl rubber synthesis, double B tyre core technology of the preparation technology and major technological breakthrough, make the service life of the butyl vulcanization capsule on the basis of original increased by more than 17%, promote domestic tire flow resistance and wet resistance both entering class B standard, will make the synthetic rubber material in the preparation of tire accounted for more than 15% higher than that of again, will promote ranks among world top class of synthetic rubber and tyre industry in China, the supply side of synthetic rubber and tire industry reform and development of high quality provides the "package" of technical solutions.
Butyl rubber is the best rubber material for air tightness.Star branched butyl rubber/brominated butyl rubber is urgently needed in the process of high-end tire industry in China to improve the life of vulcanized capsules and reduce the gas tight layer.But the production technology difficulty is big, the domestic does not have the mature star branched technology and the product.At the same time, the backward processing technology leads to the domestic tire industry lagging behind foreign countries, domestic tires and foreign advanced double B tires to be 2 ~ 3 grades.
In order to reverse the "big but not strong" passive situation of domestic synthetic rubber industry and improve the market competitiveness of China's tire industry, the ministry of science and technology listed "key technologies of synthetic rubber industrialization" in the national key research and development plan for the first time, and made it a national major industrial project to break through the bottleneck of tire industry chain.Based on its own advantages, the synthetic rubber innovation team of the research institute of petroleum and chemical industry plays the supporting role of the "gas station" of the industrial chain, and takes the lead of seven domestic scientific research institutions and universities in the rubber field, such as changchun yinghua research institute, to undertake this major industrial development project concerning the future development of the field of synthetic rubber and tires in China.
Over the past year, the project team through collaborative research, perfect the brominated butyl rubber, neutralization reaction control technology of the new technology, the development of independent intellectual property rights issued by slurry method star branched butyl rubber stable synthetic key technology, improve the overall level of the tire industry in China, after these "heavyweight" technology industrial application will make China's tire industry ranks among world top class, in the field of Chinese oil synthetic rubber at home advantage will be further consolidated, for 100000 tons/year high-end butyl rubber technology development provides the core technology of package.
