| 中文摘要: |
| 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60/40，填充体系选用炭黑N234时，硫化胶综合性能达到最佳。 |
| 英文摘要: |
| 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. |
