Abstract

The invention discloses an aqueous damping paint, which comprises the following components by weight proportion: 19-21 parts of polyvinyl butyral, 18-23 parts of PA66 resin, 20-36 parts of thickening agent, 1-2 parts of ailanthus altissima wood chip, 2-6 parts of fir wood chip, 4-8 parts of linden wood chip, 5-7 parts of calcium stearate, 9-11 parts of stearic acid, 9-14 parts of magnesium sulfate, 8-13 parts of silver sulfate, 2-6 parts of copper sulphate, 1-3 parts of hollow ceramic bead and 41 parts of sodium dodecanesulphonate. The product has wide polymer damping temperature, and has characteristics of stable property and difficult deformation during a drying process, can effectively increase the damping performance and elastic modulus, and has good physical and mechanical properties as well as flame retardation performance.

Description

technical field [0001] The invention relates to a 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 machinery and other household pro...
