▎ 摘  要

NOVELTY - Graphene oxide conductive coating 20-35 wt.% aqueous acrylic resin, 5-8 wt.% epoxy resin, 4-6 wt.% ethanol, 4-6 wt.% isopropyl alcohol, 2-3 wt.% ethylene vinyl acetate copolymer, 5-12 wt.% graphene, 5-8 wt.% zinc, 3-5 wt.% straw ash, 0-5 wt.% pigment, 1.0-3.0 wt.% dispersant, 0.1-1.0 wt.% antifoaming agent, 0.1-1.0 wt.% flatting agent and 25-40 wt.% water. The rice straw ash is prepared by completely burning and removing water-soluble salt by drying the rice. USE - Used as graphene oxide conductive coating. ADVANTAGE - The coating: has excellent storage stability and electrical conductivity, and long shelf life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene oxide conductive coating comprising (i) mixing ethanol, isopropanol and water and making into solvent, the solvent is divided into first solvent and a second solvent, where the mass ratio is 1:3, uniformly dividing the aqueous acrylic resin into first aqueous acrylic resin and second aqueous acrylic resin. The first solvent comprises aqueous acrylic resin, pigment, dispersant, zinc oxide, rice straw ash, and antifoaming agent are uniformly mixing and grinding to obtain a slurry, and (ii) mixing the slurry obtain in step (i) with second solvent, the second solvent comprises aqueous acrylic resin, epoxy resin, ethylene-vinyl acetate copolymer, graphene and flatting agent are uniformly mixing.
