采用KH570/CTAB复配改性 MoS2 ,并将改性 MoS2 与不同用量的 PVC 和橡胶进行共混 ,制备M oS2/PVC/橡胶复合材料 ,并研究了其力学性能和耐磨性能.结果表明 ,随着PVC用量的增加 ,NBR/PVC/MoS2 和CNBR/PVC/MoS2 复合材料的力学性能不断提高 ,SBR/PVC/MoS2 复合材料的力学性能保持不变或略有下降 ;M oS2/PVC/橡胶复合材料的摩擦因数和阿克隆磨耗均不断降低.“,”The molybdenum disulfide was organically modified by KH570/CTAB compound modi-fier ,and the MoS2/PVC/Rubber composites was prepared by adding MoS2 and different amount of PVC ,and physical mechanical properties and wear resistance of the composites were studied .The re-sults showed that physical mechanical properties of NBR/PVC/MoS2 composite and CNBR/PVC/MoS2 composite were improved continuously ,but physical mechanical properties of SBR/PVC/MoS2 composite remain constanted or decreased slightly with the increase of the amount of PVC .The fric-tion coefficient and the Akron abrasion of Rubber/PVC/MoS2 composites decreased with the increase of the amount of PVC .
