Abstract
The invention discloses a rubber composition, vulcanized rubber and application of vulcanized rubber. The rubber composition contains dialkene rubber, white carbon black, a hollow microbead filler and a coupling agent. Specifically, the hollow microbead filler is hollow glass microbeads, and has body density of 2.0-3.0g / cm<3> and bulk density of 1.0-1.8g / cm<3>. The hollow microbead filler contains 55-65wt% of SiO2 and 15-25wt% of Al2O3, and has an average particle size of 2-10 micrometers. The mineral phase of the hollow microbead filler is an amorphous vitreous body. The rubber composition can effectively improve the dispersion of white carbon black in a rubber matrix, and reduces the aggregation of white carbon black filler particles, so that mixed rubber can have good processing performance, the energy consumption of mixing is low, and the dynamic mechanical properties of the vulcanized rubber are also good.
Description
technical field [0001] The invention relates to a rubber composition, vulcanized rubber and the application of the vulcanized rubber. Background technique [0002] In recent years, my country's ethylene industry has developed rapidly, and my country's rapidly developing ethylene industry can provide a large amount of isoprene-containing C 5 Distillate resources make it possible to produce a large amount of ternary integrated rubber (SIBR) with excellent performance. With the decrease of fossil fuel and raw material resources, the automotive industry has more and more urgent requirements for tire energy saving, and the production of silica does not use fossil raw materials. The above factors will make SIBR / silica new green tire tread rubber a research and development It is a hot spot of application and has huge market potential. [0003] EP863182B1 discloses a rubber composition mainly used for tread rubber, its main composition is: based on 100 parts by weight of rubber: c...
