| 中文摘要: |
| 采用高结构炭黑N234分别填充溶聚丁苯橡胶(SSBR)和丁基橡胶(IIR)，对比研究填料在两种胶中的分散与相互作用，探究IIR替代SSBR提高胎面胶性能的可能性。结果发现：填料在IIR中的分散性较差，填料-填料相互作用更强，而在SSBR混炼胶中，填料-橡胶相互作用更强。相同硫化体系下，SSBR硫化胶的拉伸强度随炭黑用量增大呈线性增大，而IIR硫化胶在炭黑用量为30份时拉伸强度达到最大值，在炭黑高填充量下，其撕裂强度远高于SSBR。动态力学性能分析表明，IIR可以部分替代SSBR用于胎面胶，改善冬季轮胎或赛车轮胎的抓着性能。 |

| In this study, the dispersion of high structure carbon black N234 in SSBR and IIR and the rubber-filler interaction, filler-filler interaction were investigated, and the possibility of using IIR to replace SSBR in the tread compound was explored.The results showed that，the filler dispersion in IIR was worse than in SSBR，and the filler-filler interaction in IIR was stronger，while the filler-rubber interaction was stronger in SSBR.With same curing system，the tensile strength of SSBR vulcanizate increased linearly with the addition level of carbon black，however the tensile strength of IIR vulcanizate with 30 phr carbon black reached maximum，and the tear strength of IIR was much higher than SSBR at high filling level.The dynamic property analysis showed that，the grip performance of winter tire or race tire IIR was improved by using IIR to replace part of SSBR in the tread compound. |
