| 摘 要： | 摘要：研究在不使用任何偶联剂的条件下，白炭黑在环氧化天然橡胶（ENR）中的应用。白炭黑在天然橡胶（NR）中会发生明显的团聚，而在ENR中的团聚情况可得到明显改善，且ENR的环氧化程度越高，白炭黑的分散性越好。ENR白炭黑胶料表现出良好的抗湿滑性能和较低的滚动阻力，白炭黑用量大T20份时，ENR/白炭黑胶料的压缩生热明显低于NR／炭黑胶料。

| Abstract: | The application of silica in the epoxidized natural rubber （ENR） without coupling agent was investigated. Severe aggregation of silica was found in the natural rubber （NR）, while in the ENR the aggregation was significantly reduced. In addition, the dispersion of silica could be improved by increase of the epoxidation degree. It was found that the silica filled ENR compounds exhibited good wet skid resistance and low rolling resistance. With more than 20 parts of silica, the silica/ENR compound had much lower dynamic heat build-up than carbon black filled NR. |
