NOVELTY - Bicomponent water dispersible epoxy primer paint comprises epoxy emulsion, wear-resistant agent, antifoaming agent, graphene dispersant, titanium chrome yellow, film forming auxiliary agent, wetting agent, nano titanium dioxide, sterilizing agent, Prussian blue and deionized water as component A; and curing agent and deionized water as component B; the molar ratio between the component A and the component B is 100: 12-14; and the bicomponent water dispersible epoxy primer paint prepared by (1) placing graphene dispersant, titanium chrome yellow and Prussian blue into an ultrasonic cell crusher, and crushing to obtain uniform dispersion, (2) adding remaining component A into the dispersion obtained in step (1), and mixing uniformly under stirring condition to obtain a component A, and (3) adding B component into the component A, and stirring uniformly to obtain a mixed liquid, and removing oxygen in the mixed liquid by ultrasonic vibration. USE - Used as bicomponent water dispersible epoxy primer paint. ADVANTAGE - The paint: has strong anti-ultraviolet degradation ability and strong adhesion. The method: has simple process and low cost; and is suitable for large scale industrial production. DETAILED DESCRIPTION - Bicomponent water dispersible epoxy primer paint comprises 50-52 wt.% epoxy emulsion, 1.1-1.5 wt.% wear-resistant agent, 0.5-0.8 wt.% antifoaming agent, 0.2-0.4 wt.% graphene dispersant, 0.2-0.4 wt.% titanium chrome yellow, 1.1-1.2 wt.% film forming auxiliary agent, 0.5-0.8 wt.% wetting agent, 1-1.5 wt.% nano titanium dioxide, 1.1-1.2 wt.% sterilizing agent, 0.02-0.04 wt.% Prussian blue and deionized water (balance amount) as component A; and 26-28 wt.% curing agent and deionized water (balance amount) as component B; the molar ratio between the component A and the component B is 100: 12-14; and the bicomponent water dispersible epoxy primer paint prepared by (1) placing graphene dispersant, titanium chrome yellow and Prussian blue into an ultrasonic cell crusher, and crushing to obtain uniform dispersion, (2) adding remaining component A into the dispersion obtained in step (1), and mixing uniformly under stirring condition to obtain a component A, and (3) adding B component into the component A, and stirring uniformly to obtain a mixed liquid, and removing oxygen in the mixed liquid by ultrasonic vibration.
