摘 要: 以不饱和聚酯(UP)为增容剂、过氧化二异丙苯(DCP)为引发剂制备了玻璃纤维(GF)增强高密度聚乙烯(HDPE)复合材料,研究了UP以及DCP的用量对该HDPE/UP/GF复合材料力学性能的影响。结果表明:UP的加入明显提高了复合材料的力学性能,当UP用量为7%时,复合材料的力学性能最优;而引发剂DCP的用量亦对复合材料的性能有着显著的影响,随着DCP用量的增加,复合材料的力学性能先升后降,其中当DCP用量为0.15%时,复合材料具有最佳力学性能。另外,扫描电镜(SEM)分析结果显示,UP的加入改善了复合材料的界面黏结,从而提高了复合材料的力学性能。 The glass fiber (GF) reinforced high density polyethylene(HDPE) was prepared with unsaturated polyester (UP) as compatibilizers, dicumyl peroxide (DCP) as initiator agent. The influence of different UP and initiator dicumyl peroxide (DCP) content on properties of the HDPE/UP/ GF composite was studied. The results show that the mechanical properties of the composite increases obviously with the addition of UP, and the composite shows the best mechanical properties when the content of UP is 7%; the initiator content also has a significant influence on the performance of the composite, the mechanical properties of the composite increase at first and then decrease, and the composite has optimal mechanical properties when the content of DCP is 0.15%. Moreover, the scanning electron microscope (SEM) results show the interfacial adhesion of composite improves with the addition of UP, which enhances the mechanical properties of the composite.
