Abstract: Different catalysts for the synthesis of epoxy acrylates resin is researched, mixed catalyst of two kind tertiary amine is developed, and the effection of composite catalyst and its dosage on the synthesis of EA are discussed. The results show that for the synthesis of EA, the catalyst active order is N,N-dimethylethanolamine N,N-dimethylformamidetriethylamine triethanolamine, when the ratio of N,N dimethylethanolamine to N,N - dimethylformamide is 1, dosage ration of composite catalyst to epoxy resin is 1.0% , and this composite catalyst shows good capability of product and catalyzation for the synthesis of EA.
