NOVELTY - Preparing aqueous epoxy emulsion modified by poly-3,4-ethylenedioxythiophene/polyethyleneimine comprises mixing a 3,4-ethylenedioxythiophene monomer and a solvent, adding an initiator and stirring for reaction to prepare a poly (3,4-ethylenedioxythiophene) dispersion liquid, mixing polyethyleneimine and waterborne epoxy resin and stirring to prepare polyethyleneimine modified waterborne epoxy resin emulsion and mixing poly 3,4-ethylenedioxythiophene dispersion liquid, polyethyleneimine modified waterborne epoxy resin emulsion and auxiliary agent, shearing and emulsifying. USE - The method is useful for preparing aqueous epoxy emulsion modified by poly-3,4-ethylenedioxythiophene/polyethyleneimine. ADVANTAGE - The emulsion: improves the dispersion stability; and the anti-corrosive paint has excellent corrosion resistance and dispersion stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) aqueous epoxy emulsion modified by poly-3,4-ethylenedioxythiophene/polyethyleneimine prepared by the above-mentioned method; and (2) a anti-corrosive paint comprising 40-60 pts. wt. aqueous epoxy emulsion modified by poly-3,4-ethylenedioxythiophene/polyethyleneimine, 0-10 pts. wt. graphene dispersion, 20-50 pts. wt. filler, 1-4 pts. wt. aqueous additives and 5-20 pts. wt. water as A component and 60-70 pts. wt. aqueous epoxy curing agent as B component.
