NOVELTY - An anti-rust paint comprises 15-25 mass% styrene-acrylic emulsion, 5-10 mass% water-soluble epoxy resin, 1-5 mass% water-soluble acrylic resin, 1-5 mass% iron oxide red, 0-5 mass% graphene, 1-2 mass% zinc oxide, 20-30 mass% barium sulfate, 1-1.5 mass% conversion agent, 0.5-1 mass% conversion accelerator, 0.05-0.2 mass% flatting agent, 0.05-0.2 mass% defoaming agent, 0.1-0.3 mass% dispersing agent, 1-2 mass% thickening agent, and balance water in which conversion agent is salicylic acid, gallic acid, tea polyphenol, tannic acid, ascorbic acid, and/or oxalic acid. USE - An anti-rust paint for steel surface of road facilities, bridge, oil and gas pipeline, engineering machinery and equipment, and ships. ADVANTAGE - Anti-rust paint is environment-friendly and low-cost, has excellent physical and chemical properties and simple preparation, and does not contain organic solvent. DETAILED DESCRIPTION - An anti-rust paint comprises 15-25 mass% styrene-acrylic emulsion, 5-10 mass% water-soluble epoxy resin, 1-5 mass% water-soluble acrylic resin, 1-5 mass% iron oxide red, 0-5 mass% graphene, 1-2 mass% zinc oxide, 20-30 mass% barium sulfate, 1-1.5 mass% conversion agent, 0.5-1 mass% conversion accelerator, 0.05-0.2 mass% flatting agent, 0.05-0.2 mass% defoaming agent, 0.1-0.3 mass% dispersing agent, 1-2 mass% thickening agent, and balance water in which conversion agent is salicylic acid, gallic acid, tea polyphenol, tannic acid, ascorbic acid, and/or oxalic acid, conversion accelerator is phloroglucinol or catechol, flatting agent is polyacrylate, defoaming agent is tributyl phosphate or aqueous silicon oil, dispersing agent is unsaturated polyaminoamide, and thickening agent is polyacrylate, carboxymethyl cellulose, alginate, and/or agar. An INDEPENDENT CLAIM is included for preparation of anti-rust paint which involves mixing iron oxide red, graphene, zinc oxide, barium sulfate, dispersing agent, water, and 2/3 of the total amount of defoaming agent, dispersing to obtain pigment and filler slurry, grinding to fineness of less than or equal to 50 mu m, adding styrene-acrylic emulsion, water-soluble epoxy resin, water-soluble acrylic resin, conversion agent, conversion accelerator, flatting agent, thickening agent, and 1/3 of the total amount of defoaming agent while 1st stirring, 2nd stirring to disperse, adjusting viscosity with water, and filtering.
