生活中会产生大量的废弃钙化物，如蛋壳和贝壳。本文提出一种用表面改性鸡蛋壳粉填充聚丙烯的方法，通过熔融挤出得到聚丙烯复合材料。分析表明，经庚二酸钙改性后的蛋壳粉能有效诱导聚丙烯β晶的形成，最高达99%，使复合材料冲击强度增幅达到228%。综合考虑，当PP/蛋壳粉/庚二酸质量比在100∶5∶0．025时，复合材料可以获得最优的力学性能。
生活中會產生大量的廢棄鈣化物，如蛋殼和貝殼。本文提齣一種用錶麵改性鷄蛋殼粉填充聚丙烯的方法，通過鎔融擠齣得到聚丙烯複閤材料。分析錶明，經庚二痠鈣改性後的蛋殼粉能有效誘導聚丙烯β晶的形成，最高達99%，使複閤材料遲擊彊度增幅達到228%。綜閤攷慮，噹PP/蛋殼粉/庚二痠質量比在100∶5∶0．025時，複閤材料可以穫得最優的力學性能。

There are many kinds of waste biomass calcium compounds,such as egg-shell and shell. In this pa-per,a method that using surface modified egg-shell powder as fillers of polypropylene( PP) to make PP composites through melt extrusion was presented. According to the analysis,egg-shell powder modified by pimelic acid could induce the formation of β-crystal to PP effectively,and the highest content of β-crystal reached 99%,making the impact strength of PP composites increase by 228%. Overall consideration,PP composites would achieve their best mechanical properties when the mass ratio of PP/egg-shell powder/pimelic acid was 100∶5∶0. 025.
