▎ 摘 要
NOVELTY - A two-component water-dispersible epoxy primer paint comprises component (A) comprising 42 wt.% epoxy emulsion, 1 wt.% 3% graphene dispersion, 2 wt.% propylene glycol methyl ether, 1.5 wt.% film-forming adjuvant, 0.8 wt.% dispersant, 0.1 wt.% defoamer, 7 wt.% pigment, 32 wt.% filler, 6 wt.% antirust pigment, and remaining deionized water, and component (B) comprising 33 wt.% curing agent and 67 wt.% deionized water. USE - Two-component water-dispersible epoxy primer paint. ADVANTAGE - The primer paint has excellent water resistance and salt mist resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of primer paint, which involves mixing all components (except thickener and wetting agent), grinding or dispersing at high speed to 40 mu m, adding remaining components, and stirring. The two components are mixed during use.
