摘要
采用4种不同牌号的有机化蒙脱土(OMMT),利用机械共混法制备出了NR/OMMT纳米复合材料,研究了复合材料的力学性能和耐磨性能,进行了透射电镜(TEM)和扫描电镜(SEM)分析。结果表明复合材料的力学性能和耐磨性都有不同程度的提高。TEM结果表明制备出了分散均匀的剥离型NR/OMMT纳米复合材料,通过纳米复合材料磨耗后的磨耗图纹及SEM表面形貌进行对比分析来探讨OMMT在橡胶中的耐磨机理。
NR/OMMT nanocomposites were prepared by mechanical blending with four different kinds of homemade OMMT,and the mechanical properties and abrasion resisitence were comparatively analyzed as well as the structure of nanocomposite was characterized by TEM and SEM.The results showed that composite mechanical properties and wear resistance are improved to some extent.The completely exfoliated NR/OMMT nanocomposites with uniform dispersion in NR matrix were confirmed by TEM,and nanocomposites by SEM after the wear surface morphology were analyzed to explore OMMT in rubber in the wear mechanism.
