Abstract

The invention provides damping paint and belongs to the technical field of paint. The damping paint is mainly used for vibration and noise reduction in the fields of automobiles, trains, steamboats, airplanes, engineering machinery and the like. The damping paint is prepared from, by weight, 25-30 parts of acrylic emulsion, 40-45 parts of white mica, 18-28 parts of fire retardant, 20-40 parts of filler, 0.5-1 part of dispersant, 12-18 parts of deionized water and 5-12 parts of auxiliaries. The damping paint has good damping, sound insulation, heat preservation and flame retardation performance.

Description

technical field [0001] The invention relates to a damping coating, which belongs to the technical field of coatings. Background technique [0002] 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 products. In the field of electrical appliances, it plays the role of sound insulation, sound absorption, vibration reduction and heat preservation. The damping effect of the damping coating mainly depends on the interaction between the polymer segments in the coating, between the polymer and the filler, and between the fillers. The strength of the interaction between them directly affects the damping performance of the coating. The water-based damping paint in the prior art has low solid content, the coating film is easily deformed af...
