Background
In the continuous development process of the rubber industry, rubber products are more and more widely applied in the fields of aerospace, automobiles, industrial products and the like, but the requirements on rubber are more and more strict. Most of automobile vibration damping products are made of natural rubber, BR (butadiene rubber) and SBR (styrene butadiene rubber) are often used together to improve the technical properties of natural rubber such as aging resistance, wear resistance and fatigue life resistance, some companies also use TPI (trans-polyisoprene rubber), TBIR (trans-butadiene rubber) and the like together with the continuous development of synthetic rubber, but some natural rubber properties are lost while the rubber is used together, for example: the BR rubber can reduce the tensile strength and weaken the comprehensive processing property; SBR is used, so that the rubber product generates heat quickly in the vulcanization and use processes; when TPI is used for production, the raw rubber is hard and is not easy to process.
