【摘要】 采用超声波分散和搅拌分散方法制备粘土填充天然橡胶复合材料,用TIM研究不同分散条件下粘土的分散情况,并测定了复合材料的力学性能及老化性能.结果表明,粘土在橡胶中的分散性影响粘土胶的性能.粘土的聚集或过度的分散都会导致粘土胶的力学性能和耐老化性能的下降.粘土在橡胶中存在着一个最佳分散状态,这时,粘土对橡胶的补强性能和粘土胶的耐老化性能最好.更多还原

【Abstract】 Clay rubber composites were prepared by using ultrasonic and normal stirring dispersing method and wereinvestigated by TEM. Mechanical properties of the composite before and after aging were also determined. Dispersionof the clay in rubber affects mechanical and aging properties of the composite. Both aggregating and extra dispersingof the clay in rubber lead to the properties of the composite decreasing. There exist a right dispersion of the clay inrubber,and in this condition, the composite shows best properties.更多还原
