NOVELTY - A building fire-retardant coating material comprises 10-20 pts. wt. graphene resin functional material, 50-100 pts. wt. distilled water, and 100-200 pts. wt. aqueous epoxy resin including Ar555 epoxy resin, F44 epoxy resin, E44 epoxy emulsion, E20 epoxy emulsion, and E51 epoxy emulsion. The aqueous curing agent is Aq419, H228B. W651 and W650. USE - Building fire-retardant coating material. ADVANTAGE - The material has high strength, conductivity and specific surface area, improves flame retardant efficiency, solves flame retardant and nano synergistic agent problems, bonds graphite and epoxy resin through chemical reaction, and increases crosslinking density to reach ideal flame retardant effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of building fire-retardant coating material comprising stirring and dispersing material for 0.5-1 hour to obtain functionalized graphene mother liquid of fire-retardant coating material, uniformly mixing 25-50 pts. wt. aqueous curing agent and 50-100 pts. wt. distilled water, and mixing with coating material according to mass ratio of 1:4-5 proportion.
