环氧化天然橡胶对累托石/炭黑/天然橡胶纳米复合材料性能的影响

研究环氧化天然橡胶（ENR）对累托石（REC）/炭黑/天然橡胶（NR）纳米复合材料性能的影响。结果表明：REC/炭黑/NR纳米复合材料中填料分散均匀，REC片层呈纳米级分散；ENR改善了REC与橡胶基体间的界面相互作用，增大了复合材料交联密度，从而显著提高了复合材料的力学性能、抗切割性能和耐磨性能，且各性能增幅随ENR用量的增大而增大。;The effects of ENR on the properties of rectorite(REC)/carbon black/NR nanocompo－sites were investigated.The results showed that，the fillers were uniformly dispersed in the composites and a nano level dispersion of REC was obtained.ENR not only improved the compatibility between REC and NR matrix，but also raised the cross－linking density of the composites.Furthermore，the mechanical properties，cutting and chipping resistance and abrasion resistance of the composites were dramatically improved as the REC loading increased
