新型受阻胺光稳定剂及其合成方法探究

Study on the new hindered amine light stabilizer and its synthesis method

高分子材料长时间暴露在日光下会出现机械性能降低、材料制品变黄等一系列变化,通常需要添加光稳定剂来对此现象进行缓解。传统的光稳定剂因对紫外线吸收剂基本没有吸收作用,不能单独使用,需要配合紫外线吸收剂使用。

polymer materials exposed to sunlight for a long time will appear a series of changes such as reduced mechanical properties,yellowing of materials and products,usually need to add light stabilizers to alleviate this phenomenon,the traditional light stabilizers because of the basic absorption of ultraviolet absorbers,can not be used alone,need to be used with ultraviolet absorbers.
