摘要
采用熔融共混法，制备了聚丙烯／小麦秸秆／高岭土三元复合材料。并对复合材料的结构和力学性能进行了表征。结果表明：小麦秸秆和高岭土的加入使得复合材料的冲击性能提高，小麦秸秆质量分数为4％，高岭土质量分数为5％的复合材料的冲击强度，比聚丙烯／高岭土体系提高16．3％，比聚丙烯／麦秆体系提高28．5％；但复合材料的拉伸强度下降。微观分析表明：小麦秸秆和高岭土在复合材料中分散良好，增加了聚丙烯基体的界面效应；复合材料断面有微裂纹产生，高岭土的加入增加了小麦秸秆和聚丙烯的相容性。
In this paper, polypropylene/wheat straw/kaolin ternary composites were prepared through the melt blending method. The properties and the structure of the composites were studied. The results indi- cated that the impact performance of composites was improved. Compared with the PP/kaolin, the impact strength was improved by 16.3%, and compared with the PP/wheat straw, improved by 28.6% , when the weight percentage content of the wheat straw was 4% and kaolin was 5%. But tensile strength was decreased with the addition of the wheat straw and kaolin. Micro-analysis showed that wheat straw and kaolin dispersed homogeneously in the composites, and increased the interface effect of the composite materials system, the cross section displayed the distribution of microcrack structure. Compatibility between polypropylene and wheat straw was enhanced with the added of kaolin.
