Abstract

The present invention discloses a high damping performance aqueous damping coating material, which comprises, by weight, 40 parts of an aqueous emulsion, 40 parts of an inorganic filler, 10 parts of rubber powder, 5-15 parts of a fire retardation agent, 8-20 parts of a diester film forming auxiliary agent, 0.5-1.0 part of an aqueous dispersing agent, 0.25-0.8 part of an aqueous antifoaming agent, and 1 part of an aqueous wetting agent. The high damping performance aqueous damping coating material has beneficial effects of wide high-polymer damping temperature, stable property and deformation resistance during a drying process, effectively improved damping performance, effectively improved elasticity modulus, good mechanical property, and good fire retardation.

Description

technical field [0001] The invention relates to a water-based damping paint with high damping performance. 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 mac...
