【摘要】 介绍了受阻胺光稳定剂(HALS)的稳定机理。讨论了其他稳定剂对其光稳定效果的影响。实验表明:HALS单独使用耐候性不佳,与其他稳定剂复配使用可得较好的结果。此外,一些HALS还能改善聚合物材料的阻燃性能。更多还原

【Abstract】 The stabilizing mechanism of hindered amine light stabilizer(HALS) was introduced.The effects of another additives used with it in polymeric material were discussed.Tests showed that the weatherability by using single stabilizer was not perfect but the perfect effect could be gained by used it with another stabilizer.Otherwise,some HALS have flame retardancy,thermo aging resistance and anti-oxidation properties.更多还原
