Abstract

The invention relates to a novel tire shoulder separation-preventing agent. The tire shoulder separation-preventing agent comprises the following raw materials in percentage by mass: 15-50% of a heat stabilizer, 10-30% of reinforcing and hardening resin and 40-70% of a heat-conducting agent. The tire shoulder separation-preventing agent enhances the stability of a single-sulfur, bi-sulfur and multi-sulfur crosslink network in vulcanized rubber and has an excellent heat-conducting function, thereby enhancing reduction resistance of long-lasting high temperature aging resistance and saline water aging resistance of tire rubber and prolonging and improving the service life and the driving safety of a tire.

Description

technical field [0001] The invention relates to a novel anti-shoulder anti-air agent for tires and its preparation method and application, belonging to the technical field of fine chemicals. Background technique [0002] With the development of the road transport industry, vehicles have higher and higher requirements on the driving performance of tires, especially at high speeds, the temperature rise inside the tires, especially the shoulders, will increase significantly, because rubber materials are poor conductors of heat , the heat generated cannot be conducted out in time, so the internal temperature rise is too high, resulting in excessive accumulation of heat. If the internal temperature is too high, the tires will have empty shoulders and delamination, which will affect the service life and fuel economy, and in serious cases, safety accidents such as tire blowouts will occur. Rubber hysteresis loss and high temperature generated by friction become the bottleneck of t...
