NOVELTY - The preparation of graphene coating involves heating 1-3 pts. wt. graphene and 5-10 pts. wt. sodium sulfate decahydrate at 35 degrees C in a closed container, stirring, melting sodium sulfate decahydrate into liquid state and completely adsorbing by graphene, adding 5-10 pts. wt. microporous glass powder, cooling to room temperature, crushing to micron powder under the protection of liquid nitrogen, grinding obtained micron powder, 3-5 pts. wt. polyamide powder, 2-3 pts. wt. polyurea powder, and 1-2 pts. wt. silane coupling agent at a low temperature, adding 20-25 pts. wt. epoxy resin, 3-8 pts. wt. chlorinated paraffin powder, 3-5 pts. wt. mica powder, stirring uniformly, spraying by hot air, heating, melting sodium sulfate decahydrate, melting the graphene permeated in epoxy resin, adding the spray material to 30-35 pts. wt. deionized water and 3-5 pts. wt. isopropyl alcohol, high speed stirring and dispersing in a tank of a planetary power mixer. USE - Preparation of graphene coating. ADVANTAGE - The method enables preparation of anti-corrosive graphene coating with superior zinc content by solving the dispersion problem, and solves the problem that graphene is difficult to disperse in anti-corrosive coating.
