DETAILED DESCRIPTION - An anticorrosive coating comprises 76-87 pts. wt. DER671 Dow solid epoxy resin, 22-25 pts. wt. 582 melamine-formaldehyde resin, 27-28 pts. wt. stearalkonium chloride, 6-7 pts. wt. hydroxyacrylate, 0.5-0.7 pt. wt. oxidized modified graphene precursor, 1-3 pts. wt. gamma -aminopropyltriethoxysilane, 5-7 pts. wt. nano titanium dioxide, 3-5 pts. wt. Y-311SN-type blocked isocyanate curing agent, 12-15 pts. wt. calcined kaolin, 2-3 pts. wt. zinc chromate, 32-35 pts. wt. solvent and 0.2-0.4 pt. wt. paraformaldehyde. The oxidized modified graphene precursor is prepared by controlling temperature inside reactor at -10 degrees C, adding 20 L 6 N concentrated sulfuric acid, stirring mixture, adding 5 kg flake graphite with particle size of 400 mesh to reactor such that scales of graphite are impregnated in concentrated sulfuric acid, stirring mixture at -10 degrees C for 60 minutes, heating reactor, stirring at 5 degrees C for 20 minutes, cooling reactor, dripping 2 N sodium nitrate to reactor, reacting mixture, controlling temperature in reactor to 5-10 degrees C, reacting mixture at 10 degrees C for 2 hours, dripping 6 L 3 N potassium permanganate solution to reactor, taking peristaltic pump, controlling dropping speed comprising stage (s1) with drop rate control of 80 ml/minute and dripping amount of 2 L, stage (s2) with drip rate control of 10 ml/minute and dripping amount of 3 L and stage (s3) with drip rate control of 60 ml/minute and dripping amount of 1 L, heating reactor at 40 degrees C for 2 hours after completion of dripping, heating reactor at 40 degrees C and heating rate of 20 degrees C/hour, reflux reacting reactor for 3 hours and cooling to 35 degrees C and cooling rate of 40 degrees C/hour, dripping 10 wt.% hydrogen peroxide to reactor, cooling reactor to room temperature, centrifuging at 100 rpm in anti-riot centrifuge for 10 minutes, maintaining the mixture still, stratifying mixture, high-speed dispersing material, adding 3 kg polyethylene glycol 800 to shear machine, dispersing at 1400 rpm for 30 minutes, adding 2 L 10 wt.% sodium hypochlorite, oxidizing mixture and dispersing mixture at 1400 rpm for 30 minutes. The solvent comprises xylene, isopropyl acetate, ethylene glycol dimethyl ether and acetone in weight ratio of 13:27:20:21. An INDEPENDENT CLAIM is included for preparation of anticorrosive coating, which involves mixing DER671 Dow solid epoxy resin, 582 melamine-formaldehyde resin, stearalkonium chloride, hydroxyacrylate, oxidized modified graphene precursor, gamma -aminopropyltriethoxysilane, nano titanium dioxide, Y-311SN-type blocked isocyanate curing agent, calcined kaolin, zinc chromate, solvent and paraformaldehyde and grinding mixture.
