Embodiment 1

[0019] A preparation method of damping paint, comprising the following steps:

[0020] 1) Weigh 28 parts of acrylic emulsion, 25 parts of deionized water, put them in a stirring container, add 20 parts of filler, 35 parts of mica powder, 1 part of dispersant, 0.2 parts of defoamer, and 0.2 parts of halogen-free flame retardant , at a rotating speed of 500r / min, after stirring for 20min, a mixed solution was obtained;

[0021] 2) Add 2 parts of film-forming aid, 0.5 part of dispersant, 0.1 part of defoamer, and 0.1 part of halogen-free flame retardant to the mixed liquid obtained in step 1), stir for 10 minutes at a speed of 100 r / min, and then add The thickener can be used after adjusting the consistency.

Embodiment 2

[0023] A preparation method of damping paint, comprising the following steps:

[0024] 1) Weigh 35 parts of acrylic emulsion and 32 parts of deionized water, put them in a stirring container, add 40 parts of filler, 45 parts of mica powder, 3 parts of dispersant, 0.8 parts of defoamer, and 0.8 parts of halogen-free flame retardant , at a rotating speed of 800r / min, after stirring for 28min, a mixed solution was obtained;

[0025] 2) Add 2 parts of film-forming aids, 1 part of dispersant, 0.3 parts of defoamer, and 0.3 parts of halogen-free flame retardant to the mixed liquid obtained in step 1). Stir for 15 minutes at a speed of 110 r / min before adding The thickener can be used after adjusting the consistency.

Embodiment 3

[0027] A preparation method of damping paint, comprising the following steps:

[0028] 1) Weigh 30 parts of acrylic emulsion, 30 parts of deionized water, put them in a stirring container, add 25 parts of filler, 40 parts of mica powder, 1.5 parts of dispersant, 0.5 parts of defoamer, and 0.6 parts of halogen-free flame retardant , at a rotating speed of 600r / min, after stirring for 22min, a mixed solution was obtained;

[0029] 2) Add 7 parts of film-forming aids, 1.2 parts of dispersants, 0.2 parts of defoamers, and 0.4 parts of halogen-free flame retardants to the mixture obtained in step 1). Stir for 16 minutes at a speed of 110 r / min before adding The thickener can be used after adjusting the consistency.

[0030] In this embodiment, the filler is calcium carbonate.

Abstract

The invention provides a preparation method of damping paint and belongs to the technical field of paint. The prepared paint is mainly used for vibration and noise reduction in the fields of automobiles, trains, steamboats, airplanes, engineering machinery and the like. The preparation method includes the following steps that firstly, acrylic emulsion and deionized water are weighed out and arranged in a stirring container, filler, mica powder, dispersant, defoamer and halogen-free flame retardant are added, the mixture is stirred for 20-28 min at the rotating speed of 500-800 r / min, and then mixed liquor is obtained; secondly, a coalescing agent, dispersant, defoamer and halogen-free flame retardant are added to the mixed liquor obtained in the first step, the mixture is stirred for 10-18 min at the rotating speed of 100-120 r / min, and then a thickening agent is added for thickness adjustment. The prepared paint has good damping, sound insulation, heat preservation and flame retardation performance.

Description

technical field [0001] The invention relates to a damping paint, in particular to a preparation method of the damping paint. 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 def...
