Abstract

The invention relates to a water-based high-molecular damping coating. The coating is characterized by comprising the components in parts by weight: 20 to 50 parts of emulsion, 0.08 to 1.8 parts of a thickening agent, 0.08 to 0.25 parts of an additive AMP95, 0.45 to 2.3 parts of a dispersing agent, 0.04 to 0.23 parts of a wetting agent, 0.08 to 0.55 parts of a defoaming agent, 35 to 65 parts of powder, 0.8 to 2.5 parts of a coalescing agent, 0.8 to 2.2 parts of a cosolvent, 0.045 to 0.23 parts of an anticorrosive agent, and 3 to 12 parts of water. The coating has the characteristics of high safety, no toxic or side effects, no pollution on environment, high bonding strength, short drying time, high convenience for use, no influence on visual effect, corrosion prevention, acid-base resistance, and the like; besides, the preparation technology for the coating is simple, high in performance-price ratio, and widely applied to metal surfaces; the wide application of the coating can reduce the construction energy consumption in China prominently, and alleviate the burden brought by the development of the construction industry to the environment.

Description

technical field [0001] The invention relates to a water-based polymer damping paint. 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 prod...
