摘　　要：为了增强聚氯乙烯(PVC)基木塑复合材料的动态力学性能,加入氯化聚乙烯(CPE)对复合材料进行改性,并探究CPE对PVC基木塑复合材料性能的影响。采用动态力学分析仪(DMA)和维卡软化温度测试仪,对加入CPE的PVC/木粉复合材料进行测试,分析CPE对PVC/木粉复合材料动态力学性能及耐热性能的影响。结果表明:CPE的加入会对PVC/木粉复合材料的动态力学性能产生重要的影响,且CPE含量约为5份时,复合材料的动态力学性能最佳;但维卡软化温度、热变形温度测试结果显示,CPE的加入降低了PVC/木粉复合材料的耐热性,且随着CPE含量的增加,复合材料的耐热性逐渐减弱。In order to enhance the polyvinyl chloride（PVC） and dynamic mechanical properties of wood plastic composite material, adding chlorinated polyethylene（CPE） composite was modified, and the effect of CPE on PVC based wood plastic composite was explored. The dynamic mechanical analysis（DMA） and VEKA softening tester were used to test the effect of CPE on the dynamic mechanical properties and heat resistance of the PVC/wood flour composites with CPE. The results show that the dynamic mechanical properties of PVC/wood flour composites are greatly influenced by the addition of CPE, and the dynamic mechanical properties of the composites are the best when the content of CPE is about 5 phr. However, the results of softening point and thermal deformation temperature show that the addition of CPE is not conducive to the heat resistance of PVCIwood flour composites, and the heat resistance of the composites decreases with the increase of CPE content.
