Abstract
The present invention relates to the technical field of coating preparation, and in particular to a preparation method and device for a water-based long-term anti-rust coating, comprising: preparing a water-based resin solution, the water-based resin solution comprising one or more of a water-based epoxy resin, a water-based acrylic resin and a water-based polyurethane resin; adding an anti-rust pigment into the water-based resin solution, the anti-rust pigment comprising one or more of zinc phosphate, aluminum tripolyphosphate, molybdate and ferro-titanium black; adding a dispersant and a wetting agent, mixing them uniformly to form an anti-rust slurry; adding the anti-rust slurry, a film-forming aid, a defoaming agent, a leveling agent and a preservative into a preparation device, mixing them uniformly to form a water-based anti-rust coating; filtering the water-based anti-rust coating to remove impurities to obtain a final water-based long-term anti-rust coating, thereby improving adhesion and thus improving anti-rust performance.
