Abstract

A related aqueous high-molecular waterproof coating is characterized by comprising the following compositions in parts by weight: 20-50 parts of an emulsion, 0.08-1.8 parts of a thickening agent, 0.08-0.25 parts of auxiliary agent AMP95, 0.45-2.3 parts of a dispersing agent, 0.04-0.23 parts of a wetting agent, 0.08-0.55 parts of an anti-foaming agent, 35-65 parts of a powder material, 0.8-2.5 parts of a film-forming auxiliary agent, 0.8-2.2 parts of a cosolvent, 0.045-0.23 parts of an antiseptic, 0.1-0.3 parts of a softening agent, 0.2-0.7 parts of an ageing-resistant agent, and 3-12 parts of water. The aqueous high-molecular waterproof coating is safe, free of toxic and side effects, free of pollution to environment, high in caking strength, short in drying time, convenient to use, free of influence to visual effect, resistant to corrosion, waterproof, resistant to acids and alkalis, and the like. Also, the coating is simple in preparation technology and high in cost performance, and widely applicable to metal surfaces.

Description

technical field [0001] The invention relates to a water-based polymer waterproof coating. Background technique [0002] Traditional coatings use organic solvents as the dispersion medium, and there is a large amount of toxic and harmful gases and waste water discharged during the production process and construction application process, which pollutes the environment, the atmosphere and water resources, and seriously damages the health of production and construction personnel. . Water-based paint is a green and environmentally friendly paint that uses water as the main dispersion medium, uses inorganic and organic matter as fillers, and does not contain any toxic organic solvents. Water-based damping coating has the advantages of good flame retardancy, high adhesion, corrosion resistance, aging resistance, high damping performance and convenient construction. It is currently being widely used in automobiles, trains, ships, aircraft, construction machinery and other household...
