强威粉/氢化丁腈橡胶纳米复合材料的结构与性能

采用机械共混法制备强威粉/氢化丁腈橡胶（HNBR）纳米复合材料，研究强威粉用量对纳米复合材料结构和性能的影响。结果表明：加入少量的强威粉可显著增大复合材料的交联密度。增大强威粉用量对复合材料的应变损耗没有明显影响。当强威粉用量为20份时，复合材料的综合物理性能较好。强威粉的加入可以提高复合材料的热稳定性能。扫描电子显微镜分析显示，强威粉在HNBR中分散良好且发生取向。;The StronWi^TM KTC/HNBR nanocomposites were prepared by mechanical blending method，and the influence of addition level of StronWi^TM KTC on the structure and properties of nanocomposites was investigated.The results showed that，the crosslink density of composites was significantly increased by adding small amount of StronWi^TM KTC.As the addition level of StronWi^TM KTC increased，the friction between the polymer chains was hardly increased.The best comprehensive physical properties were obtained when the addition level of StronWi^TM KTC was 20 phr.The thermal stability of nanocomposites was also improved with StronWi^TM KTC.From SEM test it was found that StronWi^TM KTC was finely dispersed in HNBR matrix and exhibited orientation
