On December 23, 2012, the China Petroleum and Chemical Industry Federation held a seminar on the preparation of high-performance radial tire rubber composite materials and industrialization project results appraisal held in Beijing. The reporter learned that the “Magic Triangle†has long troubled the tire industry. The problem has made important breakthroughs. The overall performance index of domestic high-performance tires is comparable to that of Michelin and Goodyear's similar products, and some indicators are even better, laying the foundation for China's response to the EU tire labeling method .
Comparative inspections by authoritative organizations show that compared with ordinary tires, the high-performance tires produced by this project can achieve oil-saving rates of more than 5%, anti-slippery indexes of more than 15%, and rolling resistances that reach the European Union's B-level and have a high level. The wear resistance.
Expert team led by Du Shanyi and Mao Bingquan, academicians of the Chinese Academy of Engineering, believe that the project reveals the mechanism of high wet skid resistance and low rolling resistance of nanoparticle/rubber composites. The results obtained have effectively guided the performance of high performance rubber composites. Developed and solved the "Magic Triangle" problem with low rolling resistance, high wet skid resistance and high wear resistance tires.
It is reported that this project is a subproject of the national "863" project "Scaled Preparation Technology of Nano-Elastomer Composites for High-Performance Tire" and is jointly undertaken by Beijing University of Chemical Technology and Shandong Linglong Tyre Co., Ltd. According to Zhang Liqun, the head of the project team and the Changjiang Scholar Professor at Beijing University of Chemical Technology, the project has developed an in-situ modification and dispersion technology for the preparation of highly-filled nano-silica/rubber composites, scientifically selecting the optimal rubber matrix and blending And then formulate a scientific and rational formula for the properties of the tread compound to produce a high-performance tread compound with low rolling resistance, high wet skid resistance and excellent wear resistance, and finally through the existing production line and process. The scientific adjustment achieved mass production of high-performance radial passenger tires.
According to Wang Zujian, deputy general manager of Shandong Linglong Tire Co., Ltd., Linglong Tire has already passed technical transformation, built a demonstration production line with an annual output of 1 million high-performance meridian passenger car tires, and trial production and sales of 71,200 205/55R16 models. High performance tires. Test results and user usage from authoritative agencies show that high-performance radial passenger cars have superior performance.
At present, the project has applied for 5 invention patents, of which 1 has been authorized.
According to Zhang Liqun, in order to solve the problem of high energy consumption and low efficiency in the current nano-silica mixing process, Beijing University of Chemical Technology is committed to the research and development of new technologies.
