摘要
系统地介绍了聚氯乙烯(PVC)型材发生光氧老化的降解机理;分析了PVC型材耐候性能的影响因素,包括自身结构的内在因素和外部环境因素;例举了PVC型材在降解过程中出现的一些典型性能的变化;最后介绍了PVC型材耐候性能研究中常用的一些分析测试方法。
The mechanism of photo-oxidation of polyvinyl chloride （PVC） profile was introduced. Then effects of intrinsic and extrinsic factors on the weathering resistance of PVC profile were analyzed. Several typical changes of properties appeared during the photo-oxidation of PVC profile were illustrated. At last, a variety of analytical methods applied for the research on the weathering resistance of PVC profile were described.
