NOVELTY - The preparation method of coating involves adding graphene to hydrochloric acid solution and then mixing, reacting the mixture for 2-4 hours, adding sodium hydroxide, chlorinated polyethylene resin, polyether polyol and aqueous ethanol solution to the mixture and then heating, uniformly stirring the mixture and then reacting for 30-60 minutes, adding initiator to the mixture and then reacting for 1-3 hours, adding emulsifier and curing agent to the mixture and then decompressing and distilling for 1-3 hours. USE - The method is useful for preparation of coating. ADVANTAGE - The method enables preparation of coating with excellent corrosion resistance, electrical conductivity, strength and adhesion properties.
