摘要
研究了国产锡偶联S SBR/BR并用胶料的加工性能、物理性能及动态生热特性。研究结果表明 ,锡偶联S SBR加入适量均匀剂后门尼粘度可与BR相近 ;随BR并用量的增大 ,共混胶料的耐屈挠以及耐磨性能都有所提高 ,生热略有降低 ,强力性能下降 ;锡偶联S SBR/BR并用比为 6 0 / 40 ,填充体系选用炭黑N2 34时 ,硫化胶综合性能达到最佳。
The processibility,physical properties and dynamic heat build up of Sn coupled S SBR/BR blend were investigated.The results showed that the Mooney viscosity of Sn coupled S SBR with proper level of homogenizing agent was similar to that of BR;the flexibility,abrasion resistance and heat build up of the blend improved,and its tensile strength decreased as the proportion of BR increased;the optimal balanced physical properties of the vulcanizate were obtained when the Sn coupled S SBR/BR with the blending ratio of 60/40 and the CB N234 were used.
