摘　　要：利用熔融共混法制备高密度聚乙烯(HDPE)/水滑石(LDH)复合材料,研究乙烯-丙烯酸共聚物(EAA)对复合材料的增容作用、力学性能以及结晶行为的影响。结果表明:EAA可以促进HDPE基体的结晶速率,提高复合材料结晶度;EAA对复合材料有很好的增容作用,能明显增强LDH与HDPE之间的界面粘合,促进LDH在基体中的有效分散;力学测试表明:加了EAA的复合材料比没有加EAA的复合材料力学性能有明显提高,且能使强度和韧性同时提高。HDPE/LDH composite was prepared by meh blending method. The effect of EAA on the eompatibilization mechanical properties and crystallization behavior of the composite was studied. The results showed that the EAA could increase the crystalling rate of HDPE matrix, and improve the erystallinity of composite ; EAA could act as an effective eompatibilizer for composite,enhance the interracial adhesion between LDH and HDPE obviously,promote the dispersion of LDH in the matrix; The mechanical properties measurements showed the mechanical properties of the composite with EAA were better than those of the composite without EAA, strength and toughness of composites were strengthened by adding EAA.
