| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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 SSBR2564S 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. |
