| 中文摘要: |
| 通过动态热机械分析仪、原子力显微镜和甲苯溶胀法对白炭黑补强的溶聚丁苯橡胶（SSBR）和乳聚丁苯橡胶（ESBR）复合体系进行综合对比。结果表明，白炭黑填充的SSBR体系相较于ESBR体系，抗湿滑性能、干路面抓着力、转弯性能和滚动阻力均得以改善，而在磨耗和冰路面抓着力方面略差。140～150 ℃的混炼加工温度可以较好地控制白炭黑絮凝网络，利于获得良好的物理性能和较低的疲劳裂纹扩展速度。 |
| 英文摘要: |
| The properties of silica-filled SSBR and ESBR composites were investigated by DMA，AFM and toluene swelling. The results showed that，compared with silica-filled ESBR composites，the wet skid resistance，dry grip，cornering and rolling resistance of silica-filled SSBR composites were better，but wear resistance and ice grip were worse slightly. Meanwhile，it was found that when the processing temperature was in the range of 140～150 ℃，the silica flocculation network could be better controlled and the resulted composites possessed good physical properties and low crack growth rate. |
