NOVELTY - Anticorrosive paint comprises 40-60 pts. wt. resin, 15-20 pts. wt. graphene aqueous dispersion, 30-40 pts. wt. filler and pigment, 7-12 pts. wt. auxiliary agent, and 10-20 pts. wt. solvent, where the resin comprises 5-10 pts. wt. epoxy resin E-42, 15-20 pts. wt. epoxy resin E-20, and 20-30 pts. wt. polyurethane-epoxy resin composite emulsion. The filler and pigment is talc powder, zinc oxide, and heavy calcium carbonate mixture. The mass ratio of talc powder, zinc oxide, heavy calcium carbonate is 3-5:1:4-6. The auxiliary agent comprises e.g. dispersant, and leveling agent. USE - The anticorrosive paint is used for hydraulic pressure pipeline (claimed). ADVANTAGE - The method is simple and easy to operate, and is economical. The paint has good anti-corrosive effect, long life, excellent adhesive force and salt spray corrosion resistance property. DETAILED DESCRIPTION - Anticorrosive paint comprises 40-60 pts. wt. resin, 15-20 pts. wt. graphene aqueous dispersion, 30-40 pts. wt. filler and pigment, 7-12 pts. wt. auxiliary agent, and 10-20 pts. wt. solvent, where the resin comprises 5-10 pts. wt. epoxy resin E-42, 15-20 pts. wt. epoxy resin E-20, and 20-30 pts. wt. polyurethane-epoxy resin composite emulsion. The filler and pigment is talc powder, zinc oxide, and heavy calcium carbonate mixture. The mass ratio of talc powder, zinc oxide, heavy calcium carbonate is 3-5:1:4-6. The auxiliary agent comprises 2-4 pts. wt. dispersant, 0.4-0.8 pts. wt. leveling agent, 0.6-0.8 pts. wt. silane coupling agent, 0.3-0.4 pts. wt. thixotropic agent, 0.7-1 pts. wt. defoamer, and 3-5 pts. wt. curing agent. The solvent is aromatic and butanol mixture. An INDEPENDENT CLAIM is also included for preparing anti-corrosive paint comprising (i) taking epoxy resin E-42, epoxy resin E-20, polyurethane-epoxy resin composite emulsion, aqueous graphene dispersion liquid, dispersing agent and solvent, uniformly stirring at a speed of 100-200 revolutions/minute for 20-30 minutes, (ii) adding filler and pigment in a sand grinding tank, starting grinding, controlling rotating speed at 3500-4000 revolutions/minute, sand grinding for 2-3 hours, controlling fineness not greater than 25 mu m, filtering using 120-mesh copper filter screen, and (iii) adding step (ii) leveling agent, silane coupling agent, thixotropic agent, defoamer,and curing agent, uniformly stirring, regulating viscosity at 100-120 s, obtaining anti-corrosive paint.
