The mechanical properties of coal filled polymer composites The mechanical properties of coal/PP composites were investigated, and the effects of coal rank, particle size, surface modification of coupling and alkylation were discussed. The results show that the anthracite and bituminous coal all can be used as filler of plastic after pretreatment of part devolatilization and surface modification; The modulus of composites increase with the content of coal filler; The coupling agent is of no effect for reinforcing the coal/PP composites, except that there are new oxygenous function group forming on the surface in the process of pulverizing; The F-C alkylation reinforce coal (under 10μm)/PP composites obviously.

4煤填充高分子复合材料力学性能超细煤粉填充聚丙烯复合材料力学性能的研究结果表明，烟煤和无烟煤经过脱除部分挥发分的预处理后，都可用于与塑料共混制备复合材料；偶联剂改性对低变质程度烟煤/聚丙烯复合材料的力学性能基本不起改善作用，而对于经气流超细粉碎后的小粒径高变质程度烟煤及无烟煤则有一定的增强作用；烷基化改性在煤表面接枝了烷基，使平均粒径小于10μm的煤/聚丙烯复合材料拉伸屈服强度普遍提高，煤填充高分子复合材料可在较高含煤量情况下维持良好的力学性能。
