| 中文摘要: |
| 研究高分散无凝胶白炭黑在轮胎胎面胶中的应用，并与普通沉淀法白炭黑进行对比。结果表明，高分散无凝胶白炭黑在胶料中的分散性明显好于普通白炭黑；与使用普通白炭黑的胶料相比，使用高分散无凝胶白炭黑的胶料耐磨性能明显提高，耐屈挠性能有所提高，耐热氧老化性能稍好；采用高分散无凝胶白炭黑部分替代炭黑，胶料生热和滚动阻力明显降低，耐屈挠性能明显提高，回弹值稍大，其余性能相差不大。 |
| 英文摘要: |
| The application of the high dispersive gel-free silica in the tread compound was investigated and compared to the conventional precipitated silica.The results showed that the dispersity of high dispersive gel-free silica in tread compound was much better than that of conventional silica；the abrasion resistance of high dispersive gel-free silica compound increased significantly，the flexibility improved and the heat oxidative aging property was somewhat better；and the heat build-up and rolling resistance of rubber compound decreased significantly，the flexibility improved remarkably，the elastic resilience increased a little without any adverse effect on other properties by using high dispersive gel-free silica partly instead of carbon black. |
