Abstract: A high performance cationic epoxy resin emulsion was prepared via chemical modification. The optimum synthesis process, emulsion properties and film performances were studied. The experiment results showed that epoxy resin emulsion prepared with epoxy resin E-51 showed good stability and excellent performances, in which the dispersed phase particle size was 0. 1~0. 3 μm, pot life was 4 h, film was transparent and hardness was 2H~3H emulsifying: emulsion stability i waterbase resin.
