Embodiment 1

[0015] A kind of acrylic damping coating of the present invention, this acrylic damping coating is made up of the following composition by weight: 20 parts of water, 1 part of water-based dispersant, 10 parts of calcium carbonate, 20 parts of talcum powder, flame retardant 7 parts, 0.5 parts of water-based defoamer, 50 parts of propionate emulsion, 0.1 part of thickener, 0.1 part of damping pigment and filler, and 0.5 part of coalescent.

[0016] The preparation process of the acrylic damping coating is as follows:

[0017] 1) Put 20 parts of extracted water and 50 parts of propionate emulsion into the reaction kettle according to the proportion by weight, and stir evenly;

[0018] 2) Extract the mixture in step 1, extract 1 part of water-based dispersant, 10 parts of calcium carbonate, 20 parts of talcum powder, 7 parts of flame retardant, and 0.5 part of water-based defoamer according to the weight distribution ratio and add them to the emulsion mixture;

[0019] 3) The mix...

Embodiment 2

[0022] It differs from Example 1 in that the acrylic damping coating is composed of the following parts by weight: 35 parts of water, 3 parts of water-based dispersant, 18 parts of calcium carbonate, 35 parts of talcum powder, 11 parts of flame retardant 2 parts, 2 parts of water-based defoamer, 110 parts of propionate emulsion, 1.5 parts of thickener, 3.3 parts of damping pigment and filler, and 1.8 parts of coalescent.

Embodiment 3

[0024] It differs from Example 1 in that the acrylic damping coating is composed of the following parts by weight: 30 parts of water, 2 parts of water-based dispersant, 14 parts of calcium carbonate, 30 parts of talcum powder, 9 parts of flame retardant 1.5 parts of water-based defoamer, 80 parts of propionate emulsion, 1 part of thickener, 2 parts of damping pigment and filler, and 1.2 parts of coalescent.

Abstract

The invention discloses an acrylate damping coating and a preparation method thereof. The acrylate damping coating comprises, by weight, 20-35 parts of water, 1-3 parts of an aqueous disperser, 10-18 parts of calcium carbonate, 20-35 parts of talcum powder, 7-11 parts of a fire retardant, 0.5-2 parts of an aqueous antifoaming agent, 50-110 parts of a propionate emulsion, 0.1-1.5 parts of a thickener, 0.1-3.3 parts of a damping pigment filler and 0.5-1.8 parts of a film forming assistant. The propionate emulsion is adopted in the preparation process of the acrylate damping coating, so the damping performance of the coating in high and low temperature state is improved, and the coating also has the advantages of good noise reduction effect, non-toxicity, no peculiar smell, hard film, good gloss retention, good durability and good pollution resistance.

Description

technical field [0001] The invention relates to an acrylic damping paint and a preparation method thereof. Background technique [0002] Under the principle of developing the coatings industry based on economy, efficiency, ecology and energy, the global coatings market is developing towards water-based and solvent-free coatings that are more suitable for environmental protection. The development of water-based damping coatings is also the overall development trend of the composite coatings industry. [0003] Existing damping coatings are mainly made of coal tar pitch, polyurethane, etc. with specific fillers added. Since this type of damping coating contains a large amount of VOC, it causes serious environmental pollution. And seriously damage the health of construction workers. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an acrylic damping paint with consistent color, no color difference, no peculiar smell...
