表面改性白炭黑增强溶聚丁苯橡胶的性能

研究了增强剂种类、普通白炭黑及硅烷偶联剂双（y-三乙氧基硅基丙基）四硫化物（Si 69）改性白炭黑对溶聚丁苯橡胶（SSBR）性能的影响,并对白炭黑表面改性的2种方法进行了时比.结果表明,普通白炭黑对SSBR的增强作用不如炭黑.填充硅烷偶联剂Si 69表面改性白炭黑,与填充未改性白炭黑相比,SSBR混炼胶的加工安全性提高,硫化速率加快;SSBR硫化胶的力学性能、回弹性、耐磨性和抗湿滑性提高.与直接加入法改性白炭黑相比,预处理法改性白炭黑填充SSBR的力学性能更好,且胶料具有更好的硫化特性和耐磨性能以及更低的滚动阻力....

The effect of different reinforcers, un modified silica and modified silica with bis（ Ttrie thoxysilylpropyl）tetrasulfide （ Si 69） on properties of solution polymerized styrenebutadiene rubber （SSBR） was studied, and the comparison was con ducted between two methods of surface modification. The results showed that the reinforcement of unmodi fied silica was worse than that of carbon black. Compared with the SSBR filled with unmodified sili ca, the processing safety of the compound was im proved, the curing rate was accelerated; and themechanical properties, resilien
