| 摘 要： | 分别用釜内聚合和机械熔融混合方法制备高岭土填充UHMWPE基复合材料,对其热性能,结晶性、聚集态结构和与45钢对摩的滑动摩擦磨损性能进行了实验研究,并分析了复合材料的摩擦磨损特性与其结构之间的联系。结果表明,釜内聚合法制备的复合材料具有比较好的性能,良好的性能源于高度分散的高岭土颗粒的增强作用和较高的界面结合强度,也与UHMWPE的结晶形态有关。 |

| Abstract: | Kaolin filled UHMWPE composites were prepared by melt mixing and polymerization respectively. Their thermal properties, crystallizability, aggregate structure and tribological behaviors sliding against 45 steel were tested and studied thoroughly, and the relationship between the tribological behavior and the structure was analyzed. It was found that the polymerization-filled composites have much better tribological properties than the mixing-filled ones with the same components, and the relevant properties are closely related to the reinforcement of kaolin particles dispersed evenly, the combining strength of the interface and the crystal patterns. |
| Keywords: | Kaolin filled UHMWPE composite crystallizability aggregate structure tribological behavior |
