摘　　要：本文采用二氧化硅、炭黑和还原铁粉三种填料对UHMWPE交联体系进行填充改性,采用模压烧结成型法制备了改性UHMWPE交联塑料,实验结果表明:三种填料对磨损率的影响比较一致,当二氧化硅含量6%、炭黑含量8%、还原铁粉含量2%时,磨粒磨损率最小。在磨粒磨损实验中,还原铁粉的含量对磨粒磨损率的影响最大。In this paper, cross-linking UHMWPE was modified by reduction iron power, carbon black and silicon dioxide, then modified plastics was gained by compression molding and sintering method. The experiment results showed that：the influence of three kind fillers is consistent to the rate of wear. When the silicon dioxide content is 6%, carbon black content is 8%, reducible Fe content is 2%, the abrasive rate of wear is smallest. In the abrasive attrition experiment, the influence of the content of reducible Fe is the biggest to the rate of abrasive wearing.
