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. |
