用适用于胎面胶的天然橡胶配方评估了具有非活性芳烷基和活性氯烃基基团的一系列硅烷偶联剂。评估结果表明,配合[2-(4-氯甲基-苯基)-乙基]-三乙氧基-硅烷的白炭黑填充胶具有最高的补强指数以及低的生热、磨耗减量和60℃下的滞后损失。[2-(4-氯甲基-苯基)-乙基]-三乙氧基-硅烷适合于白炭黑填充胎面天然橡胶配方,因为配合[2-(4-氯甲基-苯基)-乙基]-三乙氧基-硅烷的配方预示着具有更低的滚动阻力和更长的磨耗寿命。
A series of silane coupling agents with non-reactive aralkyl and reactive chlorinated hydrocarbyl groups were evaluated using a natural rubber formulation suitable for tread rubber. The evaluation results show that the silica filler with [2- (4-chloromethyl-phenyl) -ethyl] -triethoxy-silane has the highest reinforcing index and low heat generation and wear reduction And hysteresis loss at 60 ° C. [2- (4-Chloromethyl-phenyl) -ethyl] -triethoxy-silane is suitable for natural rubber formulations filled with white carbon black because [2- (4-chloromethyl- ) -ethyl] -triethoxy-silane is predictive of lower rolling resistance and longer wear life.
