摘要
研究了纳米SiO2及超细玻璃微珠颗粒填充改性超高分子量聚乙烯(UHMWPE)塑料的性能,重点研究了材料耐热性能的提高。结果表明:在UHMWPE中添加少量经有机长链偶联剂表面处理的纳米SiO2或超细玻璃微珠对材料的耐热性能有显著影响。而UHMWPE复合材料耐热性的提高对扩大其应用领域有着重要的现实意义。通过分折实验数据得到了不同填充量填充的复合材料的维卡温度、拉伸强度、硬度曲线,确定了最佳改性条件和填充效果。
The effects of ultra-high molecular weight polyethylene (UHMWPE)-based composites filled with nano-silica or ultra fine glass microballoon on resistance to heat and mechanical properties were investigated.The improvement of resistance to heat was studied as the focus.It was shown that the resistance to heat,tensile strength and hardness of UHMWPE-based composites were greatly affected by a small quantities of fillers,which were surface modified by long-organic-chain coupling agent,so that the UHMWPE-based composites could be used in more fields.According to the experimental data,the curves of various filler quantities to vicker tempetature,tensile strength and hardness were gained,that contributed to the determination of best filler quantity and modification conditions.
