摘　　要：用废弃皮粉改性促使聚丙烯具备生物降解性与良好韧性,但由于废弃皮粉与聚丙烯难以相容,因此将聚乙烯马来酸酐接枝物作为增容剂,提高二者相容性以及废弃皮粉在聚丙烯中的分散均匀性,从而制备建筑用皮粉基高分子复合材料。通过性能测试发现,废弃皮粉属于束状纤维状结构,具备增强增韧作用;随废弃皮粉含量不断增加,复合材料的拉伸强度先增后降,而断裂伸长率却不断下降;在废弃皮粉含量增加时,复合材料的冲击性能先增后降,超出15份时出现下滑;废弃皮粉含量5份时,复合材料耐热性能较高,其他含量下,相对于纯聚合物,耐热性能较低。In order to improve the biodegradability and good toughness of polypropylene,waste leather powder was modified.However,it is difficult to be compatible with polypropylene.Therefore,polyethylene maleic anhydride graft copolymer was used as compatibilizer to improve the compatibility and dispersion uniformity of waste leather powder in polypropylene,so as to prepare building leather powder based polymer composites.Through the performance test,it is found that the waste leather powder belongs to bundle fibrous structure,which has the effect of strengthening and toughening;With the increase of waste leather powder content,the tensile strength of the composites first increases and then decreases,while the elongation at break decreases;When the content of waste leather powder increases,the impact properties of the composites first increase and then decrease,and decline when the content exceeds 15 phr;When the content of waste leather powder is 5 phr,the heat resistance of the composite is higher than that of pure polymer.
