| 摘 要： | 以聚丙烯（PP）、废瓦楞纸板制取的植物纤维为原料，采用马来酸酐接枝聚丙烯（MAH-g-PP）、铝酸酯偶联剂、铝钛偶联剂为界面相容剂，研究了植物纤维增强PP复合材料的力学性能。结果表明：未添加界面相容剂时，随着植物纤维用量的增加，复合材料冲击强度急剧下降，弯曲强度和拉伸强度上升；添加界面相容剂MAH—g—PP后。当植物纤维的质量分数为30％时，复合材料的弯曲强度和拉伸强度均达到最大值；在MAH—g-PP、铝酸酯偶联剂、铝钛偶联剂三者中，MAH—g—PP改善植物纤维与PP之间的界面相容性效果最佳；当MAH-g-PP添加质量为植物纤维添加质量的10％时，复合材料的冲击强度、拉伸强度、弯曲强度及综合性能最佳。

| Abstract: | PP and recycled corrugated paper board as the raw material and MAH-g-PP, aluminum ester and aluminum-titanium compound coupling agent were used to investigate the mechanical performance of fiber reinforced PP composites. The results show that: the tensile strength increases while the impact strength decreases with the loading of fiber without solubilizer; both the bending and tensile strength reaches the highest point when the MAH-g-PP loading stays at 30wt%; among the three mentioned coupling agents, MAH-g-PP is superior to modify the interface; the impact strength, tensile strength and bending strength obtain an optimized value when the MAH-g-PP content is 10% to fiber filled. |
