摘要
以氯化聚乙烯(CPE)为增韧剂,通过热压成型制备了不同配比的改性聚氯乙烯(PVC)膜材。利用热重分析仪(TG)、动态热力学分析仪(DMA)、傅里叶红外光谱仪(FTIR)和能谱仪(EDS)考察了CPE的添加对改性PVC膜材热性能、动态力学性能、耐紫外光老化性能的影响。结果表明:引入CPE能够较好地改善纳米颗粒在PVC基体中的分散效果,并在一定程度上延缓了PVC膜材的老化。同时,改性PVC膜材具有较好的耐低温性能,当温度低于-30℃时,CPE用量为7.5份的膜材依然具有较高的储能模量。
With chlorinated polyethylene（CPE） as toughening agent, a series of modified polyvinyl chloride（PVC） membranes were prepared by hot-compaction method. The influences of CPE content on thermal properties, dynamic mechanical properties and anti-ultraviolet aging performance of the modified PVC membranes were investigated by thermogravimetric analysis（TG）, dynamic thermal mechanical analysis（DMA）, Fourier transform infrared spectrometry（FTIR） and energy dispersive spectrum analysis（EDS）. The results show that CPE can effectively improve the dispersing effect of nano particles in PVC matrix, and the aging behavior of PVC membranes can be slowed down. Meanwhile, the modified PVC membranes have low temperature resistance. When the content of CPE is 7.5 phr, the membranes still have a high storage modulus under-30℃.
