Abstract

The invention discloses a green environment-friendly high-performance water-based damping paint which is prepared from the following components in parts by weight: 35-50 parts of water-based emulsion, 25-30 parts of inorganic filler, 9-10 parts of rubber powder, 1-3 parts of modified wollastonite, 8-13 parts of polyethylene methyl ether methacrylate, 9-17 parts of methyl methacrylate, 8-20 parts of double-ester film-forming assistant, 0.5-1.0 part of water-based dispersant, 0.25-0.8 part of water-based defoaming agent and 1 part of water-based wetting agent. The product has the advantages of wide high-polymer damping temperature, stable properties and low deformation tendency in the drying process, can effectively enhance the damping capacity and elastic modulus, and has favorable physical and mechanical properties and flame retardancy.

Description

technical field [0001] The invention relates to a green and environment-friendly water-based 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. [0003] 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 ma...
