【摘要】 对比研究白炭黑填充溶聚丁苯橡胶/顺丁橡胶(BR)、乳聚丁苯橡胶/BR和丁苯吡橡胶(VPSBR)/BR复合材料的性能。结果表明:白炭黑在VPSBR/BR并用胶中的分散较好,相应胶料定伸应力较高,0℃下的tanδ较大,耐磨性能较好;提高VPSBR/BR并用胶中BR用量可降低胶料60℃下的tanδ,且耐磨性能变化不大。更多还原

【Abstract】 The properties of silica filled solution polymerized butadiene-styrene rubber(SSBR)/butadiene rubber(BR),emulsion polymerized butadiene-styrene rubber(ESBR)/BR and vinylpyridine-butadiene-styrene rubber(VPSBR)/BR composites were comparatively investigated.The results showed that,VPSBR/BR composite filled with silica had better silica dispersion,higher modulus,higher loss factor(tanδ) at 0 ℃ and the best wear resistance.With the increase of BR content in VPSBR/BR composites,the tanδ of the composites at 60 ℃decreased,and the wear resistance was kept excellent.更多还原
