环氧酚醛衍生物的检测方法与应用

Detection Method of Epoxy Derivatives and Its Application

以金属包装涂料中双酚A类环氧衍生物为研究对象,开展了对其检测方法、迁移规律和工艺优化方面的研究。探讨了BADGE,BFDGE及其衍生物的高效液相色谱-荧光检测方法,并将该检测方法用于涂料生产工艺的优化。并最终确定了最优的生产工艺条件,即烘烤温度为190℃,涂膜厚度为11g/m2,烘烤时间为12min。在此工艺条件下,BFDGE,BADGE,BADEG.2H2O,BFDEG.2H2O的残留质量浓度最少,分别为0.066,0.047,0.092,0.071μg/mL。

The bisphenol A and epoxy derivatives in metal can inwall coating, as object of research, were studied on its determination method, migration regulation and process optimization. A high performance liquid chromatography with fluorescence detection method was carried out to investigate the migration of BFDGE, BADGE and their hydrolysis derivatives, and then this method was applied to process optimization. The optimum conditions were： baking temperature at 190℃, coating thickness of 11 g/m2, baking time of 12 min. Under these conditions, the residual volume of BFDGE, BADGE, BADEG.2H2O, BFDEG.2H2O were minimum, and of 0.066 μg/mL, 0.047μg/mL, 0.092μg/mL, 0.071 μg/mL, respectively.
