摘要

采用流动性较高的高密度聚乙烯为流动改性剂,纳米SiO₂为成核剂,乙烯-丙烯酸酯类共聚物为相容剂,对超高分子量聚乙烯(UHMWPE)进行了加工性能和机械性能等的改性研究。结果表明:高密度聚乙烯用量为10％～15％、纳米SiO₂用量为2％～3％、相容剂用量为8％～10％时,得到的复合改性聚合物的力学性能和耐磨耗性均不逊于国内外市场上知名产品,综合性能良好。

Abstract

The modified research of processability and mechanical performance to Ultra-high molecular weight polyethylene(UHMWPE) was did using high-density polyethylene as flow modifier,nano-silica as nucleating agent,and ethylene-acrylate copolymer as compatilizer.The results shown that modified polymer had comprehensive performance as good as well-known products of domestic and international market in mechanical performance and abrasion resistance.
