| 摘 要： | 以鸡西发电厂粉煤灰为原料,选择钛酸酯为表面处理剂,对不同粒度的粉煤灰进行表面处理,对其活化指数、润湿接触角、包裹牢固度等指标进行测定。并将改性后的粉煤灰样品填充于橡胶制品中,测试填料对橡胶的补强作用。实验表明,粉煤灰的粒度对橡胶的补强性能有很大的影响,经过钛酸酯偶联剂处理后,粒度级为小于0．0432mm的粉煤灰对橡胶具有较好的补强作用,可部分替代碳黑,减少碳黑的用量,降低橡胶的成本,减少对环境的污染。

| Abstract: | The fly ash with different sizes from Jixi power plant was treated with titanate as surface coupling agent to modify the fly ash surface properties. The properties of fly ash surface including active index, wetting angle, oil absorption rate etc. were measured. The modified fly ash was filled into rubber to increase it properties. The result is shown that, the size of fly ash has a great affected on the rubber properties. The modified fly ash of -0.0432mm grade exhibits the best performance in respect to rubber properties. Also the fly ash can take the place of some decomposition, so that the dosage of decomposition in rubber can be reduced resulting the low producing cost of rubber and the low pollution of fly ash. |
