| 中文摘要: |
| 研究国产双端基官能化溶聚丁苯橡胶（SSBR）2055DF在高性能乘用车轮胎胎面胶中的应用。结果表明：与进口双端基官能化SSBR（SOL5251H）相比，SSBR 2055DF的门尼粘度、乙烯基质量分数、重均相对分子质量及玻璃化转变温度均略高，相对分子质量分布较窄；采用SSBR 2055DF等量替代SSBR SOL5251H用于205/55R16 91V高性能乘用车轮胎胎面胶中，胶料的硫化特性相当，硫化胶的动态力学性能提高，成品轮胎的高速和耐久性能相当，滚动阻力下降，湿地制动性能略有提高，同时可降低生产成本。 |
| 英文摘要: |
| The application of domestic diend-functionalized solution polymerized styrene butadiene rubber（SSBR） 2055DF in the tread compound of high-performance passenger car tires was studied.The results showed that compared with imported diend-functionalized SSBR（SOL5251H），the Mooney viscosity，vinyl mass fraction，weight-average relative molecular weight and glass transition temperature of 2055DF were slightly higher and the relative molecular weight distribution was narrower.Using SSBR 2055DF as an equivalent substitute instead of SSBR SOL5251H in the tread compound of 205/55R16 91V high-performance passenger car tire，the vulcanization characteristics of the compound were comparable，the dynamic mechanical properties of the vulcanizate improved.The high-speed performance and durability of the finished tire were comparable，the rolling resistance was reduced and wet braking performance was slightly improved,，while the production costs could be reduced. |
