不同牌号高苯乙烯溶聚丁苯橡胶在胎面胶中的应用

Application of Different Grades of High Styrene Content Solution Polymerized Butadiene Styrene Rubber in Tread Compound

研究4种牌号高苯乙烯溶聚丁苯橡胶(SSBR)在胎面胶中的应用。结果表明:4种牌号高苯乙烯SSBR的微观结构基本一致,相对分子质量及其分布略有差异;4种牌号高苯乙烯SSBR胎面胶的硫化特性、加工性能、老化前后物理性能和动态力学性能相当,4种牌号SSBR在相同配方体系下可以实现相互替换。

The application of four grades of high styrene content solution polymerized butadiene styrene rubber(SSBR)in tread compound was studied.The results showed that the microstructure of the four grades of high styrene content SSBR was basically consistent,with slight differences in the relative molecular weight and distribution.The vulcanization characteristics,processing performance,physical properties before and after aging and dynamic mechanical properties of the four grades of high styrene content SSBR tread compounds were equivalent.The four grades of SSBR could be replaced with each other under the same formulation system.
