Abstract

The invention relates to a water-borne acrylic resin anticorrosive coating and a preparation method thereof, and belongs to the technical field of coatings. The water-borne acrylic resin anticorrosive coating is prepared from, by weigh , 30-55 parts of modified acrylic emulsion, 16-25 parts of water-borne epoxy resin, 10-16 parts of silica sol, 4-6 parts of aluminum triphosphate, 5-15 parts of anticorrosive pigment, 20-40 parts of pigment filler, 0.5-5 parts of additive and 10-15 parts of water. The water-borne acrylic coating has the advantage of being long in storage time, and still has the good coating property after being stored for 12 months or longer.

Description

technical field [0001] The invention relates to a water-based acrylic resin anticorrosion coating and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] The research on acrylic monomers and resins began in 1805, but due to limited conditions, it was not produced industrially by Rohm & Haas until 1927, and the real application in coatings was after 1953. Acrylic paints are developed today. It is already a type of synthetic resin coating with the most types, the most comprehensive performance, and the strongest versatility. Compared with other polymer resins, acrylic resin coatings have many outstanding advantages, such as its excellent light resistance, weather resistance, and outdoor exposure durability. Strong, not easy to decompose and turn yellow under ultraviolet light, can maintain the original luster and color for a long time, good heat resistance; corrosion resistance, good resistance to acid, alkali, salt, gre...
