摘　　要：β-PP具有优良的性能，但低刚性和较差的耐磨性限制了其应用。本文采用β—PP与尼龙6及增容剂共混的方法，制备了兼具良好力学性能和耐磨性能的β—PP／PP—g—MAH／PA6三元共混物。实验结果显示：三元共混物的弯曲强度和拉伸强度较纯β-PP相比均有提高，冲击性能略微下降，摩擦性能得到了明显的改善。发现PA6的用量为20wto％，增容剂为5wt％时，共混物的整体性能最佳。β--PP shows excellent performance. But the low rigidity and poor wear resistance limits its application. We blended β- PP and PA6 with compatibiiizer to prepare β--PP/PP--g--MAH/PA6 blends with both good mechanical properties and wear resistanc. The results showed bending strength and tensile strength of blends were improved compared with pure β--PP and Slight decrease in impact properties. But friction performance is significantly improved. Taking all factors into consideration, the optimal mass ratio of β- PP/PP--g--MAH/PA6 composites for reaching optimum properties should be 75/5/20.
