Abstract

The invention relates to a waterborne acrylic polyurethane surface paint. The paint is prepared from the raw materials of, by weight: 150 to 200 parts of waterborne acrylic resin, 200 to 300 parts of deionized water, 1 to 3 parts of an antifoaming agent, 180 to 200 parts of titanium pigment, 1 to 3 parts of a neutralizer, 2 to 6 parts of aluminum tripolyphosphate, 100 to 150 parts of precipitated barium sulfate, 10 to 20 parts of a rheological auxiliary agent, 2 to 4 parts of a flash corrosion inhibitor, 25 parts of saponite, 1 to 3 parts of a leveling agent, and 0.5 to 2 parts of a catalyst. The paint provided by the invention has the following advantages: 1. environment pollution is reduced, and energy is saved; 2. the paint has strong adhesive forces on various base materials, and the coating has high hardness, good water resistance, good weatherability, good chemical resistance, and relatively high wear resistance; 3. the paint can be used as terrace and floor paint, metal rust-resisting paint, ship paint, and can be applied on automobiles, light industrial products and drinking-water cylinder inner walls for preventing corrosion.

Description

Technical field: [0001] The invention relates to a coating, in particular to a water-based acrylic polyurethane topcoat. Background technique: [0002] With the continuous progress of society, the awareness of environmental protection in various countries continues to increase. However, the widely used solvent-based coatings contain a large amount of volatile organic compounds (VOC), which are toxic, flammable, pollute the atmosphere, and cause harm to the environment and human body. Therefore, in order to reduce the pollution of these organic solvents to the environment, my country has included water-based coatings in the future development direction of industrial coatings. However, the water resistance, chemical resistance, abrasion resistance and weather resistance of the water-based industrial coatings currently used in floor coatings, metal antirust paints and ship coatings in my country are not ideal. Invention content: [0003] The object of the present invention ...
