Abstract: Solutionpolymerized styrenebutadiene rubber (SSBR) was mainly used in tire, such as tread, carcass and sidewall, because of its excellent abrasion resistance and low temperature performance. But compatibility between SSBR with SiO2 is poor due to its nonpolar . In order to improve compatibility between SSBR with SiO2, series of modified SSBR were prepared by grafting with maleic anhydride (MAH) as graft monomer. The properties of composites composed by SSBR and SiO2 were studied and influence of grafting yield of SSBRgMAH was also investigated. The results showed that the contact angle of SSBRgMAH was decreased, the Mooney viscosity was increased after grafted with MAH and the mechanical properties of rubber was improved when curing time was extended. Dynamic mechanical testing showed that wet skid resistance of vulcanizates was improved and rolling resistance reduced, which will be an ideal material for tire tread.

摘要： 溶聚丁苯橡胶( S S B R) 由于其优良的耐磨、 耐低温等性能, 主要用于轮胎的胎面、 胎体和胎侧等部位,但由于S S B R是一种非极性橡胶, 使得它与白炭黑等极性填料的结合力较弱。为了提高S S B R与白炭黑的相容性,以马来酸酐( MAH) 为极性单体对S S B R进行接枝改性。研究了接枝聚合物( S S B R - g - MAH) 与白炭黑共混后的胶料的各项性能, 探讨了接枝率对胶料性能的影响。结果表明, 溶聚丁苯橡胶接枝了 MAH 后, 接触角降低, 门尼黏度增大, 硫化时间延长, 胶料的综合力学性能有不同程度的提高。动态力学( DTMA) 测试表明, 接枝 MAH 后实现了胶料抗湿滑性能的提高和滚动阻力的降低, 为轮胎胎面胶提供了理想的材料。
