| 摘 要： | 采用物理共混改性的方法，制备了具有不同性能的超高分子量聚乙烯／石墨合金。研究了填料含量对合金性能的影响，DSC分析结果表明UHMWPE的热分解温度在455℃而熔点超过140℃，拉伸强度随石墨的添加明显下降，当石墨含量为5％时其拉伸强度下降到O．24MPa，冲击强度和摩擦磨损性能的测试结果表明，石墨填料的加入可以一定程度的改善合金材料的冲击性能和耐磨性能，石墨含量为1％时合金的摩擦系数由原来的0．14下降到0．12，而石墨较少时其冲击强度亦有所提高。

| Abstract: | The ultra-high molecular weight polyethylene / graphite alloys with different properties were prepared through physical blending method. The influence of filler content on the properties of alloys was studied. The results of DSC analysis showed that the thermal decomposition temperature of UHMWPE was 455℃, and its melting point was more than 140℃ It was found that the tensile strength declined significantly with the addition of graphite. When the graphite content was 5% the tensile strength decreased to 0.24 MPa. The results of impact strength and friction tests showed that the impact and friction resistance could be improved by adding graphite to a certain degree. When the graphite content was 1%, the alloy＇s friction coefficient decreased from 0.14 to 0.12. The impact strength increased even when there was a small amount of graphite. |
