摘要
以甲基丙烯酸缩水甘油酯接枝高密度聚乙烯(HDPE-g-GMA)作为聚酰胺66/超高摩尔质量聚乙烯(PA66/UHMWPE)共混合金的增容剂,采用熔融法制备了PA66/UHMWPE/HDPE-g-GMA共混合金。通过Molau试验、SEM观察和力学性能测试,研究了HDPE-g-GMA在熔融共混过程中对PA66/UHMWPE共混合金的增容作用。结果表明:HDPE-g-GMA与PA66发生了化学反应,所生成的接枝共聚物对PA66/UHMWPE共混合金有较好的增容作用;PA66/UHMWPE共混合金的界面形态和力学性能均有较大改善,吸水率也有所降低。
By means of melting extrusion process, the polyamide 66 （PA66）/ultra high molecular weight polyethylene （UHMWPE）/high density polyethylene graft glycidyl methacrylate （HDPE-g-GMA） blends were prepared, in which the high density polyethylene graft glycidyl methacrylate （HDPE-g-GMA） acted as reactive compatibilizer of PA66/UHMWPE. The HDPE-g-GMA as a compatilizer to PA66/UHMWPE blends was studied through Molau experiment, scanning electron microscopy （SEM） observation, and mechanical property test. The result showed that the grafted copolymer, which was produced by HDPE-g-GMA and PA66 being in chemical reaction during melt blending had a good compatibilization on PA66/UHMWPE blends. Interfacial morphology and mechanical property of PA66/UHMWPE blends were improved obviously, meanwhile the water absorption decreased.
