溶聚丁苯橡胶RC2557S在轿车子午线轮胎胎面胶中的应用

Application of Solution Styrene-Butadiene Rubber RC2557S in Tread Compound of Passenger Car Radial Tire

研究溶聚丁苯橡胶(SSBR)RC2557S在轿车子午线轮胎胎面胶中的应用,并与进口SSBR进行对比。结果表明,SSBR RC2557S能够满足欧盟环保要求,其微观结构、硫化特性、物理性能和动态力学性能与进口同类产品相近。采用SSBR RC2557S生产轿车子午线轮胎胎面胶,成品轮胎的滚动阻力达到C级,湿地抓着性能达到B级,符合出口欧盟的要求。

The application of solution styrene-butadiene rubber （SSBR） RC2557S in the tread com- pound of passenger car radial tire was investigated, and compared with imported SSBR. The results showed that,SSBR RC2557S met the EU environmental requirements, and the microstructure, curing behavior,physical properties and dynamic mechanical properties of SSBR RC2557S were similar to the imported SSBR. By using SSBR RC2557S to produce the tread compound of passenger car radial tire, the rolling resistance of finished tire reached grade C and the wet grip performance reached grade B, which met the requirements for export to EU.
