摘要
对比研究采用相同体积分数的炭黑和白炭黑分别补强溶聚丁苯橡胶(SSBR)和乳聚丁苯橡胶(ESBR)胎面胶的性能。试验结果表明:与炭黑填充丁苯橡胶(SBR)胶料相比,经偶联剂Si69(用量为白炭黑用量的8%)热处理的白炭黑填充SBR胶料的分散性改善,硫化胶的300%定伸应力增大,拉断伸长率减小,抗湿滑性能提高,滚动阻力和动态生热降低,耐磨性能和抗切割性能较差。
The properties of SSBR and ESBR tread compound filled with the same volume fraction of carbon black or silica were investigated.The test results showed that,compared with carbon black filled SBR compound,the dispersity of SBR compound filled with silica in-situ modified by coupling agent Si69（the amount was 8% of silica amount） was better,the modulus at 300% elongation of vulcanizate increased,and the elongation at break decreased,the wet skid resistance was improved,and the rolling resistance and dynamic temperature rise decreased,but the abrasion resistance and cut-resistance were poor.
