摘　　要：研究低顺式聚丁二烯橡胶(LCBR)在高用量白炭黑胎面胶中的应用。结果表明:与高顺式聚丁二烯橡胶(BR9000)相比,LCBR的微观结构明显不同,玻璃化温度升高12℃;LCBR等量替代BR9000后,胶料的门尼粘度略有升高,加工性能略差,物理性能基本相当,动态力学性能明显提升,滚动阻力降低。The application of low cis-polybutadiene rubber(LCBR)in the tread compound with high dosage silica was studied.The results showed that,compared with high cis-polybutadiene rubber(BR9000),the microstructure of LCBR was significantly different,with a glass transition temperature increase of 12℃.After replacing BR9000 with LCBR,the Mooney viscosity of the compound slightly increased,the processing performance was slightly worse,the physical properties were basically equivalent,the dynamic mechanical properties were significantly improved,and the rolling resistance was reduced.
