Example Embodiment
[0014] Example 1
[0015] The acrylic damping coating of the present invention is composed of the following ingredients in parts by weight: 20 parts of water, 1 part of water-based dispersant, 10 parts of calcium carbonate, 20 parts of talc, and 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 film-forming aid.
[0016] The preparation process of the acrylic damping coating is as follows:
[0017] 1) Extract 20 parts of water and 50 parts of propionate emulsion according to the proportion by weight, put them into the reactor and mix, and stir evenly;
[0018] 2) Extract the mixture of step 1, extract 1 part of aqueous dispersant, 10 parts of calcium carbonate, 20 parts of talc, 7 parts of flame retardant, and 0.5 parts of aqueous defoamer according to the weight distribution ratio and add them to the emulsion mixture;
[0019] 3) The mixture of extraction step 2 is...
Example Embodiment
[0021] Example 2
[0022] The difference from Example 1 is that the acrylic damping coating is composed of the following ingredients in parts by weight: 35 parts of water, 3 parts of water-based dispersant, 18 parts of calcium carbonate, 35 parts of talc, and 11 parts of flame retardant. Parts, 2 parts of water-based defoamer, 110 parts of propionate emulsion, 1.5 parts of thickener, 3.3 parts of damping pigments and fillers, and 1.8 parts of film forming aids.
Example Embodiment
[0023] Example 3
