摘　　要：制备环氧度为15%的环氧化溶聚丁苯橡胶(ESSBR),以其作为大分子偶联剂对白炭黑/顺丁橡胶(BR)复合材料进行改性,研究白炭黑/ESSBR/BR复合材料的性能,并与偶联剂Si69/白炭黑/溶聚丁苯橡胶(SSBR)/BR复合材料进行对比。结果表明,白炭黑/ESSBR/BR复合材料的白炭黑分散性、拉伸性能、抗湿滑性能和耐磨性能均有不同程度的提高,滚动阻力降低,且无挥发性有机化合物的排放,该复合材料可用于轮胎胎面胶。An epoxidized solution polymerized styrene butadiene rubber(ESSBR)with epoxy degree of 15%was prepared and used as a macromolecular coupling agent to modify silica/butadiene rubber(BR)composites.The properties of the silica/ESSBR/BR composites were studied,and compared with the coupling agent Si69/silica/solution polymerized styrene butadiene rubber(SSBR)/BR composites.The results showed that the silica dispersion,tensile properties,wet skid resistance and wear resistance of the silica/ESSBR/BR composites were improved,the rolling resistance was reduced,and there was no emission of the volatile organic compounds.These composites could be used in tire tread compounds.
