摘　要：用硫化仪考察了橡胶助剂3-苯并噻唑硫代-1-丙基-三乙氧基硅烷(Silane-M)对丁苯橡胶/白炭黑复合材料硫化性能的影响.结果表明,Silane-M可明显缩短丁苯橡胶/白炭黑复合材料的正硫化时间,但不影响其焦烧时间.Silane-M具有一定的促进作用,可以加快硫化速率.未添加和添加6份(质量)Silane-M的丁苯橡胶/白炭黑复合材料在135～160 ℃的硫化温度系数和硫化反应表观活化能均比较接近,2种复合材料的硫化性能对温度的依赖性基本一致.

Abstract：The effect of rubber additive 3-benzothiazolthio-1-propyl-triethoxylsilane(Silane-M) on vulcanization behavior of styrene butadiene rubber(SBR)/silica composites was investigated with rubber curometer. The results showed that Silane-M shortered vulcanization time, but had no effect on scorching time. It could accelerate rubber vulcanization process. The vulcanization temperature coefficient and apparent vulcanization activation energy of silica filled rubber without and with 6 phr Silane-M at 135-160 ℃ were approximately equal. The temperature dependence of vulcanization behavior of two kinds of composites were basically consistent.
Keywords：3-benzothiazolthio-1-propyl-triethoxylsilane; styrene butadiene rubber; silica; composite; vulcanization behavior
