In this paper,water-based epoxy curing agent in different application fields was synthesized by the preliminary pre-polymerization of epoxy resin solution and amine compounds with different hydrophilic groups through the exploration of water-based epoxy curing agent research scheme,reference formula and synthesis process.After a lot of experiments and exploration,the curing agent prepared by N,N’-bis(3-aminopropyl)ethyl ethylamine and epoxy resin solution has better performance in the strengthening adhesive,and the curing agent prepared by N-methyl-1,3-propanediamine or 1,3-bis(hydroxymethyl)urea and epoxy resin solution has the same performance as the products sold in the waterborne epoxy anticorrosive coating.
