炭黑/蒙脱土/SBR纳米复合材料的性能研究

采用少量（0～5份）蒙脱土（MMT）等量替代炭黑，考察炭黑/MMT/SBR纳米复合材料的硬度、强伸性能、耐磨性能和耐屈挠龟裂性能。结果表明，随着炭黑/MMT并用比的减小，炭黑/MMT/SBR纳米复合材料的拉伸强度、撕裂强度和耐屈挠龟裂性能明显提高，耐磨性能有所下降，但降幅不大。;The hardness，mechanical properties，abrasion resistance，and flex fatigue life of carbon black/montmorillonite(MMT)/SBR nano-composites were investigated with low level(0～5 phr）MMT replacing the same level of carbon black.The results showed that the tensile strength，tear strength and flex fatigue life of carbon black/MMT/SBR nano-composites were obviously improved with decreasing the ratio of carbon black to MMT，while the abrasion resistance of nano-composites decreased slightly
