The epoxy acrylate emulsion was made by hybrid emulsion polymerization. This method has simple technology, none solvent and friend to the environment. The epoxy acrylate hybrid emulsion was prepared by using core-shell emulsion polymerization technology. The factors, such as epoxy resin, emulsifier ,initiator and functional monomer, were investigated by the orthogonal experiment. The relation of interactional factors was confirmed, and one kind of steady emulsion was made. The best formulation condition of modified emulsion could be obtained when N-MA was 1%, MAA was 2%, emulsifier was 3%, epoxy resin was 6%, initiator was 0.6%. The structure of modified styrene acrylic hybrid emulsion was characterized by FT-IR, the peaks at 915cm-1 and 1251cm-1 correspond respectively to the motion of epoxy group and phenylate, so the graft polymer was confirmed.
