Abstract

Water-based acrylic polyurethane top-coat is prepared from the following raw materials by a weight proportion: 150-200 parts of water-based acrylic resin, 200-300 parts of deionized water, 1-3 parts of defoamer, 180-200 parts of titanium dioxide, 1-3 parts of neutralizing agent, 2-6 parts of aluminium triphosphate, 100-150 parts of precipitated barium sulphate, 10-20 parts of rheological assistant, 2-4 parts of flash rusting inhibitor, 25 parts of talcum powder, 1-3 parts of flatting agent and 0.5-2 parts of catalyst; the top-coat is characterized by also being prepared from 2-4 parts of antioxidant, 1-4 parts of nanometer magnesium sulfide and 1-4 parts of ultraviolet light absorber. The water-based acrylic polyurethane top-coat is non-pollution, better in water resistance, chemical resistance, abrasive resistance and weather fastness, long in service life and high in hardness.

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 ...
