▎ 摘  要

NOVELTY - Organic/inorganic hybrid modified graphene water-based epoxy micaceous iron oxide intermediate paint comprises component A and component B. A component comprises 60-80 wt.% aqueous epoxy emulsion, 4 wt.% ethylene glycol monobutyl ether and balanced amount of organic/inorganic hybrid graphene silica sol. The B component comprises 25-27 wt.% epoxy curing agent, 30-32 wt.% antirust pigment filler, 15-20 wt.% grey mica iron oxide, 1-2 wt.% dispersant, 0.5-1.0 wt.% antifoaming agent, 0.8-1.2 wt.% anti-settling agent, 3-3.5 wt.% thickening agent 0.4 wt.% flatting agent, 2 wt.% ethylene glycol monobutyl ether acetate, 2wt.% ethylene glycol monobutyl ether and balanced amount of deionized water. USE - Organic/inorganic hybrid modified graphene water-based epoxy micaceous iron oxide intermediate paint used as an environment-friendly coating. ADVANTAGE - The organic/inorganic hybrid modified graphene aqueous epoxy micaceous iron intermediate paint has good dispersibility in the water washing paint, improves the uniformity of the film, the large layer structure of the graphite greatly improves the adhesive force and corrosion resistance of the paint, and has good application prospect. The self-electrostatic adsorption effect of graphite improves the anti-settling performance of the coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing organic/inorganic hybrid modified graphene water-based epoxy micaceous iron oxide intermediate paint, which involves preparing a component A and a component B, and uniformly mixing the component A and the component B according to the mass ratio of 1: 0.4-0.5 to obtain organic/inorganic hybrid modified graphene water-based epoxy micaceous iron oxide intermediate paint, the component A contains organic/inorganic hybrid graphene silica sol.
