▎ 摘  要

NOVELTY - Reinforced concrete composite coating comprises solvent-free primer comprising epoxy, reactive diluent, epoxy curing agent, and tannic acid; and solvent-free high-solids graphene finish comprising epoxy, reactive diluent, graphene, antirust pigments, fillers, wetting dispersants, anti-settling agents, and epoxy curing agents. USE - Composite coating used for reinforced concrete (claimed). ADVANTAGE - The coating prolongs service life of reinforced concrete. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of reinforced concrete composite coating comprising mixing epoxy resin, reactive diluent and tannic acid uniformly, grinding mixture to fineness of not greater than 5 mu m, and adding epoxy curing agent to obtain solvent-free primer; and mixing mixture with graphene powder, wetting dispersant, reactive diluent and epoxy resin uniformly, grinding into fineness of not greater than 30 mu m, adding pigments and antirust pigments, grinding continuously to not greater than 30 mu m fineness, adding anti-settling agent and epoxy curing agent; and (2) protecting reinforced concrete by removing loose attachments on surface of reinforced concrete base; applying solvent-free primer to surface of reinforced concrete base, curing at room temperature to form primer layer, coating solvent-free high-solid graphene finish on primer layer, and curing at room temperature to form topcoat layer, where reinforced concrete base is bridge, offshore platform, railroad subgrade, or transmission tower base.
