摘　　要：对比研究4种高苯乙烯溶聚丁苯橡胶(SSBR)/高分散性白炭黑复合材料在电动汽车轮胎胎面胶中的应用。结果表明:SSBR KC3737T/白炭黑9100GR复合材料的填料分散性最好;SSBR F3438K/白炭黑9100GR复合材料的耐磨和抗湿滑性能最好,滚动阻力最低,以此复合材料生产的轮胎的高速和耐久性能均满足国家标准要求,滚动阻力系数、通过噪声和抗湿滑指数分别达到了ECE R117法规的B,Ⅱ和B级。The application of four high styrene solution polymerized styrene butadiene rubber(SSBR)/highly dispersible silica composites in the tread compound of electric vehicle tires was comparatively studied.The results showed that the filler dispersion of SSBR KC3737T/silica 9100GR composite was the best.The wear resistance and wet slip resistance of SSBR F3438K/silica 9100GR composite were the best,and its rolling resistance was the lowest.The high speed performance and durability of the tire produced with the SSBR F3438K/silica 9100GR composite met the requirements of national standards,and the rolling resistance coefficient,passing noise and wet slip resistance index reached the B,Ⅱand B levels of ECE R117 regulations,respectively.
