2,2'-二羟基-4,4'-二甲氧基二苯甲酮

用途

【用途一】
用作紫外线吸收剂
【用途二】
该品为二苯甲酮类紫外线吸收剂。紫外线吸收剂是目前使用最普遍的光稳定剂，这是一类能够强烈地、选择性地吸收高能量的紫外光，并进行能量转换，以热能形式或无害的低能辐射将能量释放或消耗的物质。含有一个邻位羟基的二苯甲酮只吸收380nm以下的紫外光，几乎不吸收可见光。该品在270-380nm波长范围内有强烈吸收，适用于聚氯乙烯、丙烯酸树脂、环氧树脂、酚醛树脂、硝酸纤维素和聚氨酯类。但该品可吸收一部分可见光，使制品稍带黄色。对大白鼠口服LD50为3000mg/kg。
【特性与用途】
紫外线吸收剂UV-12
【131-54-4】
能有效吸收320-400nm波长紫外光，特别适应于色浅、透明织物的应用，其光、热、化学稳定性均优于UV-9(BP-3),目前广泛用于聚酯、氯乙烯、环氧树脂、树脂镜片、太阳膜、贴纸、高档化妆品，新型高档涂料、油漆中，还被国外应用于织物中。
