▎ 摘  要

NOVELTY - High-resistance salt spray anticorrosive paint, comprises 60-80 wt.% aqueous acrylic emulsion, 5-15 wt.% deionized water, 0.1-0.3 wt.% pH regulator, 0.2-0.6 wt.% wetting agent, 0.1-0.5 wt.% antifoaming agent, 1-2 wt.% dispersant, 0.5-2 wt.% graphene powder, 10-20 wt.% flatting agent, 1-5 wt.% cosolvent, 2-5 wt.% rust conversion agent, 0.5-2 wt.% antirust agent and 0.2-0.8 wt.% thickening agent, where wetting agent more than one polyether modified polysiloxanes, the defoaming agent is more than one of polyether modified siloxane copolymer emulsions containing fumed silica, the dispersant is an aqueous copolymer solution containing pigment affinity groups, the flatting agent is more than one inorganic toners with good weather resistance, the co-solvent is dipropylene glycol methyl ether and/or alcohol ester-12, the thickeners are nonionic polyurethane thickeners and alkali swellable thickeners of acrylate copolymers. USE - Used as high-resistance salt spray anticorrosive paint. ADVANTAGE - The paint is environmentally friendly, has good stability, strong adhesive force, fast drying, good salt mist property, excellent aging resistance, good water resistance, convenient construction, low cost, non-combustible, no pollution, low temperature storage without deterioration, has convenient and fast construction, smooth and smooth paint film, and good hand feeling. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the paint, comprising (i) adding the aqueous high salt spray emulsion, deionized water, pH adjuster, wetting agent, and defoamer into the paint mixing tank in sequence, and stirring at 800-1000 revolutions/minute, (ii) adding dispersant, graphene powder and toner, and stirring at 1000-1200 revolutions/minute for 30 minutes, and the fineness is less than or equal to 20 mum, (iii) adding the co-solvent according and stirring at 1000-1200 revolutions/minute for 10 minutes, (iv) adding rust conversion agent and anti-flash rust agent in sequence, and stirring at 1000-1200 revolutions/minute for 10 minutes, and (v) adding thickener, stirring at 600-800 revolutions/minute for 10 minutes, and measuring the viscosity.
