NOVELTY - Preparation method of graphene coating, involves mixing 42-47 pts. wt. carbamate, 12-18 pts. wt. 4-nitro-N-(3-triethoxysilylpropyl) benzamide, 10-14 pts. wt. N-(3-trimethoxysilylpropyl)pyrrole, 25-29 pts. wt. p-hydroxyphenyl acrylic acid, 9-13 pts. wt. methyl p-hydroxycinnamate, 7-10 pts. wt. monobutyl ether, 6-9 pts. wt. cinnamaldehyde grafted tapioca starch, 20-25 pts. wt. inorganic flame retardant, 1-5 pts. wt. ricinoleic acid amide monoethanolamine (MEA), 6-11 pts. wt. 2,3-butanediol, 1-3 pts. wt. leveling agent, 2-5 pts. wt. thickener, 0.5-1 pt. wt. coupling agent, 0.5-0.8 pt. wt. defoamer, 5-20 pts. wt. graphene/modified graphene and 40-46 pts. wt. deionized water, and homogenizing at 82-87 degrees C at a speed of 12000-14000 rpm for 4-5 minutes to obtain a graphene coating. USE - The method is used for preparation of graphene coating (claimed). ADVANTAGE - The graphene coating utilizes graphene which has high dispersibility, firm bonding, and is not easy to fall off, and simultaneously graphene interacts with other substances to form a complex network structure, and simultaneously has high antistatic properties and impact resistance. The method ensures simple whole preparation process, low cost, no environmental pollution in the production process, and stable quality.
