preparation example Construction

[0011] A method for preparing water-based damping paint cured at room temperature. The order of adding materials in the preparation process needs to be carried out according to certain steps. First, the solid filler is mixed evenly for standby, and the water-based acrylic emulsion, dispersant, film-forming agent, half of the amount of defoamer, and the attached Mix the accelerator, antirust agent and purified water evenly, add the mixed filler, continue to mix until the paint is fine and free of obvious particles, add the other half of the amount of defoamer, thickener, and multifunctional additives, and adjust to a suitable viscosity , the first half of the defoamer is used to suppress the generation of air bubbles during the mixing process, and the second half of the defoamer is used to reduce the retention of air bubbles in the coating.

Embodiment 1

[0025] Mix 41 parts of calcium carbonate, 9 parts of mica powder, 3 parts of attapulgite and 2 parts of polypropylene fiber evenly and set aside. In addition, 30 parts of emulsion I; 8 parts of alcohol ester twelve; 0.45 parts of silicone defoamer; 0.8 parts of dispersant; 0.7 parts of adhesion promoter, 0.3 parts of zinc phosphate, and 3 parts of purified water were put into a planetary mixer and stirred Uniformly; add the well-mixed filler, and continue to stir at a medium speed for 1 hour; detect that there is no obvious filler agglomeration particle, add 0.45 parts of silicone defoamer, 1.2 parts of thickener, 0.1 part of multifunctional additive, and vacuum defoam after stirring evenly. Made into water-based damping coating cured at room temperature.

Embodiment 2

[0027] Mix 30 parts of calcium carbonate, 12 parts of mica powder, 2 parts of attapulgite and 2 parts of sepiolite fiber and set aside. In addition, 40 parts of emulsion II; 7 parts of alcohol ester twelve; 0.35 parts of mineral oil defoamer; 0.4 parts of dispersant; 0.7 parts of adhesion promoter, 0.3 parts of zinc phosphate, and 3 parts of purified water were put into a planetary mixer and stirred Uniformly; add the well-mixed filler, and continue to stir at a medium speed for 1 hour; detect that there is no obvious filler agglomeration particle, add 0.35 parts of mineral oil defoamer, 1.8 parts of thickener, 0.1 part of multifunctional additive, and vacuum defoam after stirring evenly. Made into water-based damping coating cured at room temperature.

Abstract

The invention relates to a normal-temperature curable waterborne damping paint, which is composed of the following raw materials by weight: 30-50 parts of a water-based acrylic emulsion; 35-55 parts of filler; 0.2-1 part of a dispersing agent; 3-10 parts of a film-forming agent; 0.3-1 part of a defoaming agent and 0.3-1 part of an adhesion promoter; 0.1-0.4 part of an antirust agent; 1-4 parts ofpurified water; 0.5-3 parts of a thickening agent; and 0.05-0.3 part of a multifunctional assistant. The damping paint has the advantages of high damping properties, strong bonding force, high self-strength, flash rust resistance, corrosion resistance, environmental friendliness and the like.

Description

technical field [0001] The invention relates to a normal-temperature curing water-based damping coating among sound-insulating and noise-reducing materials, and the product is used in transportation fields such as automobiles, rail vehicles, and airplanes. Background technique [0002] People like to obtain a quiet and comfortable riding environment when taking transportation. Noise is produced by mechanical vibrations. The role of the polymer damping material is to convert the kinetic energy into heat energy through the internal friction of the material when the vibration of the noise is transmitted to the material, reducing the vibration energy and reducing the noise. For a long time in the past, polymer damping materials were all solvent-based products. During use, a large amount of harmful ingredients are released, and the organic volatiles inside it can be continuously released for several years, seriously endangering producers and users. Water-based damping material...
