摘　　要：研究3种混炼工艺对丁腈橡胶(NBR)改性白炭黑填充溶聚丁苯橡胶(SSBR)性能的影响。结果表明:无论采用哪种混炼工艺,以NBR1846或NBR3305改性白炭黑填充SSBR胶料的t90缩短,硫化速率加快,硫化胶的抗湿滑性能提高,滚动阻力降低;当采用先混炼NBR和白炭黑、再加SSBR的工艺时,NBR3305改性白炭黑填充SSBR硫化胶的动态力学性能最好。The effect of three mixing processes on the properties of the SSBR compound filled with NBR modified silica was investigated. The results showed that, for all three processes, the tg0 of the SSBR compound filled with the silica modified by NBR1846 or NBR3305 was shortened,the curing speed was accelerated,the wet skid resistance of the vulcanizates was improved, and the rolling resistance was decreased. By using the mixing process in which NBR was firstly mixed with silica,and then with SSBR,the SSBR vulcanizate filled with NBR3305 modified silica showed the best dynamic properties.
