Embodiment 1

[0034] A water-based sound-absorbing, heat-insulating and fire-resistant coating of the present invention, said water-based sound-absorbing, heat-insulating and fire-proof coating comprises the following components by mass percentage:

[0035]

[0036]

[0037] The wetting agent is a non-ionic low-foaming alkyl polyoxyethylene ether, such as Dow's BD-109, Clariant's LCN407, and the present embodiment selects Dow's BD-109;

[0038] Described thickener is hydroxyethyl cellulose, prevents the sedimentation of heavy pigment and filler, introduces yield value and thixotropy for coating system, as the 250HBR of Ashland; Thickener B is polyurethane thickener; The leveling agent is matched with non-ionic polyurethane thickening and leveling agent, such as RM2020 or RM2050D of Dow Company, and RM2020 is selected in this embodiment. The two thickeners are used together to effectively adjust the rheological behavior of the paint at low, medium and high shear rates to obtain interio...

Abstract

The invention discloses a water-based sound-absorbing heat-insulating fireproof coating and a preparation method thereof. The invention belongs to the technical field of indoor coatings. The coating is prepared from the following components in parts by mass: 20-35 parts of deionized water, 0.2-0.5 parts of a thickening agent A, 0.1-0.3 parts of a thickening agent B, 0.1-0.3 parts of a wetting agent, 0.3-0.8 parts of a dispersing agent, 0.4-0.6 parts of a defoamer, 3-5 parts of a coalescing agent, 0.1-0.3 parts of a pH value stabilizer, 1-2 parts of an anti-freezing agent, 20-30 parts of VAE emulsion, 10-15 parts of titanium dioxide, 5-10 parts of perlite, 15-20 parts of porous powder quartz, 0.6-1.2 parts of a leveling agent and 0.2-0.5 parts of a bactericidal mildew preventive. The product is non-toxic, harmless, low in cost, free of environmental pollution, high in covering power and excellent in heat insulation, sound absorption and fire prevention effects.

Description

technical field [0001] The invention relates to the technical field of indoor coatings, in particular to a water-based sound-absorbing, heat-insulating and fire-resistant coating and a preparation method thereof. Background technique [0002] Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. According to different purposes and objects of use, it can be divided into: decorative fireproof coatings, cable fireproof coatings, steel structure fireproof coatings, prestressed concrete floor fireproof coatings, etc. Among them, decorative fire retardant coatings are getting more and more attention in the architectural coatings industry. But at present, the fireproof coatings for decorative walls pay more attention to the decorative effect, and the fireproof effect is not ideal. [0...
