摘要
采用机械共混法制备了凹凸棒土(AT)/氯丁橡胶(CR)纳米复合材料,探讨了AT用量、改性剂种类及用量和硫化剂体系等对复合材料耐磨性能的影响,还观察了使用不同改性剂制备的复合材料阿克隆磨耗表面形态。结果表明,AT用量为30份时复合材料耐磨性最好;改性剂KH-550能显著提高硫化胶耐磨性,其最佳用量为AT用量的3%;硫化体系不同时复合材料的耐磨性有所不同,采用MgO/ZnO/DCP(质量比为4/5/1)并用硫化体系时复合材料耐磨性最好。
Attapulgite(AT)/chloroprene rubber(CR) composites was prepared by using mechnical mixing technology, and effects of AT content, modifier kinds and content and curing systems on wear- ability of the composites were discussed, and the surface morphology of Akron abrasion of the compos- ites having the different modifiers was observed, too. The results showed that the wearability of the composites was the best when the amount of AT was 30 phr;Modifier KH--550 was an effective coupling agent in increasing the wearability of the composites, and the optimal content was 3 % of AT content;The wearability was different by using different curing systems. The wearability of the composites was the best when curing agents MgO/ZnO/DCP mass ratio was 4/5/1.
