摘要/Abstract

摘要： 实验采用熔融共混-模压法制备了废弃玻璃钢(WGFRP)/聚丙烯(PP)复合材料。研究了硅烷偶联剂KH550表面改性WGFRP、改性聚丙烯(MAPP)添加量以及乙烯-辛烯共聚物(POE)的使用对WGFRP/PP复合材料性能的影响。实验结果表明,KH-550表面改性WGFRP能使复合材料性能小幅度提高,MAPP可使复合材料的拉伸和弯曲强度分别提高28.63%、20.13%,添加POE后,复合材料的断裂伸长率和冲击强度增幅分别达到152.36%、45.43%。扫描电镜图片显示,多种改性剂的加入有效改善了WGFRP和PP的界面粘合程度,宏观表现为复合材料性能提高。

Abstract: Polypropylene matrix composites(WGFRP/PP)filled with the Waste Glass Fiber Reinforced Plastics(WGFRP)debris was prepared by the banburying and mould pressing. The influences of WGFRP powder modified with silane coupling agents KH550, the amount of Modified Propylene Polymer (MAPP), Polyolefin elastomer (POE) to WGFRP/PP composite performance were studied. The results show that composite performance was enhanced a little with WGFRP powder modified with KH550, for which the tensile strength and flexural strength were increased by 28.63% and 20.13% with MAPP, respectively. The breaking elongation and impact strength were improved by POE, showing an increase of 152.36%, 45.43%, respectively. The SEM images show that the interfacial adhesion between WGFRP and PP is good by using agents. It presented improved performance macroscopically.
