尼龙6具有良好的耐磨性,由于自身的吸水性而限制了其应用.本工作采用多单体接枝增容聚合物共混新技术,利用烯烃类聚合物自身的润滑性、以及耐吸水性,通过与尼龙6复合来改善尼龙6的吸水性和摩擦磨损性能.将自制的PP-g-(MAH-co-St),PP-g-(GMA-co-St)和PP-g-(MMA-co-St)三种相容剂添加到PA6/PP共混物中,熔融挤出造粒,注塑成型,制得PA6/PP为80/20的不同相容剂增容的聚合物共混物.研究了不同相容剂对PA6/PP共混合金吸水性和摩擦磨损性能的影响.结果表明:自制的三种相容剂都能够在不同程度上改善PA6/PP共混材料的吸水性.其中,PP-g-(GMA-co-St))对PA6/PP共混体系增容、耐水性及耐磨性改善效果最好.
