Abstract

The invention provides high solid content water-based damping paint, which is formed by proportioning the following main compositions in mass ratio: 40 to 60 parts of water-based emulsion; 30 to 50 parts of inorganic stuffing; 5 to 20 parts of rubber powder; 5 to 15 parts of fire retardant; 8 to 20 parts of film-forming assist agent; the solid content of the water-based emulsion is 40 to 70 percent and is formed by mixing water-based crylic acid solution with nuclear shell structure and inter-penetrating network emulsion; and the granularity of flaky mica powder is between 40 meshes to 200 meshes. The high solid content water-based damping paint is produced through the steps: configuration of water-based emulsion, addition of stuffing and assist agent, film formation and paint regulation. The product can be used for the shock absorption and noise reduction of a vibration basal body, has wide polymer damping temperature and stable property and difficult deformation during the drying process, can effectively improve the damping performance and the elastic modulus, can ensure that the obtained polymer material has good physical and mechanical performance as well as retardant performance, at the same time has low production cost which is lower than that of the similar product both at home and abroad, and has promising market prospect.

Description

technical field [0001] The invention relates to a water-based damping paint and a preparation method thereof, in particular to a high-solid-content water-based damping paint and a preparation method thereof. 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 cons...
