不同牌号溶聚丁苯橡胶在轮胎胎面胶中的应用性能

Application Property of Different Brand SSBR in Tire Tread Compound

研究3种牌号溶聚丁苯橡胶(SSBR)在轮胎胎面胶中的应用性能。结果表明:RC2557S胶料的门尼粘度最大,但流动性最好;RC2564S硫化胶的耐磨性能和抗湿滑性能最好,压缩温升最低;RC2557S,RC2564S和LG2550胶料的硫化特性、物理性能和滚动阻力相当,3种牌号SSBR在相同配方体系下可以实现相互替换。

The application properties of three brands of solution polymerized styrene butadiene rubber(SSBR)in the tire tread compound were investigated.The results showed that the Mooney viscosity of RC2557S compound was the highest,but its fluidity was the best.The wear resistance and wet skid resistance of RC2564S vulcanizate were the best,and the compression heat build-up was the lowest.The curing characteristics,physical properties and rolling resistance of RC2557S,RC2564S and LG2550 compound were similar.These three brands of SSBR could be used to replace each other in the same formula system.
