| 摘 要： | 通过红外光谱分析、紫外吸收光谱分析、扫描电镜分析、白度分析和阿伦尼乌斯方程回归分析,研究了PVC材料的光稳定性。结果表明:①PVC材料老化过程中,引起白度变化的主要原因是双键的生成,尤其是共轭多键的生成;②添加紫外吸收剂JC568可有效抑制PVC材料的老化,当用量为0.3份时,效果最好。

| Abstract: | The photostability of PVC materials was studied by infrared absorption spectroscopy analysis,UV-spectroscopic analysis,scanning electron microscopy analysis,whiteness analysis and Arrhenius equation regression analysis.The results show that：（1） the formation of double bonds,especially many conjugated double bonds,are the main reasons for the whiteness change of PVC materials during aging;（2） the adding of ultra-violet absorbent JC 568 can efficiently prevent the aging of PVC materials,and the best effects are obtained when its dosages are 0.3 parts. |
