Modifing epoxy resin using acrylic monomers,the waterborne epoxy-acrylic emulsion was synthesized.Epoxy resin was modified by graft copolymerization with acrylic monomers and the strong hydrophilic group —COOH was interlinked in chain.This article studied the conditions,which without emulsifier,acrylic monomers were grafted onto the epoxy with solution polymerization method.The epoxy-acrylic resin composite solution was got at temp 120 ℃,time 6 h.After neutralized with amines and diluted with water,the water emulsion was obtained.And the emulsion properties：Define：39 %;Stability：60 min.Best film curing conditions： temp at 150 ℃,time at 60 min.The film properties： Adhesion：0;Impact resistance：50 cm;Water resistance：7 d;Flexibility：15 mm.
