摘　　要：试验研究溶聚丁苯橡胶(SSBR)2564S在冬季轿车子午线轮胎胎面胶中的应用。结果表明:在冬季轿车子午线轮胎胎面胶中采用SSBR2564S替代乳聚丁苯橡胶(ESBR)1723,并调整炭黑/白炭黑并用比例,胶料的邵尔A型硬度较低,300%定伸应力和拉伸强度略有降低,低温下(0℃)邵尔A型硬度变化较小,湿地抓着性能较好,滚动阻力较低;工艺性能良好;试制的185/60R14轿车子午线轮胎的强度性能、耐久性能和高速性能良好,且实际应用中轮胎在冰雪路面上操控性能优良。The application of solution polymerized styrene-butadiene rubber（SSBR）2564S in the tread compound of winter passenger car radial tire was experimentally investigated. The results showed that,by using SSBR2564 S instead of emulsion polymerized butadiene styrene rubber（ESBR）1723,and adjusting the proportion of black carbon/silica incorporation in the tread compound,the hardness of tread compound was lowered,the modulus at 300% elongation and tensile strength decreased slightly,the change of hardness at low temperature（0 ℃） was small,and the tread compound possessed good wet skid resistance and low rolling resistance,and the processing property was good. The trial 185/60R14 passenger car radial tire possessed good high speed performance,endurance performance and strength performance,and had excellent control performance on the snow ground in practical application.
