摘要
本文介绍了二苯甲酮类紫外线吸收剂国内外发展及其光稳定化机理,着重介绍了紫外线吸收剂 UV—B 的合成工艺及其性能,证明该品种是一种工艺简单,成本低廉,性能优良的新型紫外线吸收剂,同时也指出了二苯甲酮类紫外线吸收剂应向多功能及反应型方向发展。
This paper describes the development of benzophenone type ultravioletabsorbers at home and abroad and its photo-stabilizing mechanizm.And emphati-cally,the synthesis process and properties of ultraviolet absorber UV-B areintroduced.It is proved that UV-B is a new ultraviolet absorber with the ad-vantages of simple technology,low cost,and excellent properties.Meanwhile,It is pointed out that multifunctionality and reactive are the direction of benzo-phenone type ultraviolet absorbers developing trends.
