Abstract

The invention discloses a water-borne damping paint with a high solid content. The paint comprises the following components in parts by weight: 80-95 parts of aqueous emulsion, 20-30 parts of an inorganic filler, 11-16 parts of gallic acid, 9-17 parts of nanometer calcium sulfate, 3-5 parts of a titanate coupling agent, 0.002 part of nano silver, 36-45 parts of hydroxyethyl acrylate, 37-45 parts of isobutyl methacrylate, 9-14 parts of Schizonepeta straw powder, 5-9 parts of redispersible latex powder and 2-6 parts of a water repellent agent. The paint disclosed by the invention has the advantages of relatively wide superpolymer damping temperature, excellent mechanical properties and flame retardant properties and is stable in property and uneasily deformed during the drying process and the damping performance and elastic modulus can be effectively improved.

Description

technical field [0001] The invention relates to a water-based damping paint with high solid content and 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, air...
