研究了白炭黑/炭黑并用体系对溶聚丁苯橡胶(SSBR)加工性能、力学性能和动态力学性能的影响,并对填料分散性进行了研究.结果表明,白炭黑和炭黑并用时可提高补强效果,白炭黑/炭黑并用比为30/20时的硫化胶综合力学性能最佳;TEM观察结果表明,填料与SSBR基体的临界界面模糊,填料分散较为均匀,填料网络化程度降低.“,”Effects of silica / carbon black combination on process property,mechanical properties and dynamic mechanical properties were investigated,and the filler dispersion was also studied.The results showed that the reinforcing effect was improved by using silica/carbon black combination.Excellent comprehensive performance of the vulcanizate was obtained when the blending ratio of silica/carbon black was 30/20.TEM observation results showed that the interface between filler and SSBR was fuzzy,and the filler dispersion was uniform,and the fillers network density was low.
