摘要
以在产电动汽车轮胎胎面胶配方为基本配方,分别采用不同牌号的溶聚丁苯橡胶(SSBR)做等量替换,研究SSBR微观结构对胎面胶硫化特性、物理性能和动态力学性能的影响.结果表明,在胶料各项性能相当的前提下,采用乙烯基含量较高的双末端官能化SSBR的胶料具有更低的滞后损失,进而使轮胎的滚动阻力更低.
Abstract
Taking the tread formula of electric vehicle tires in production as the basic formula,different grades of solution polymerized styrene butadiene rubber(SSBR)were used for equal replacement,and the effect of SSBR microstructure on the curing characteristics,physical properties and dynamic mechanical properties of the tread compound were studied.The results showed that under the premise that the properties of the compounds were equivalent,the double-end functionalized SSBR with higher vinyl content had lower hysteresis loss,thereby lowering the rolling resistance of the tire.
