Abstract

The invention discloses a heat-preservation and heat-insulation coating and a preparation method thereof. The heat-preservation and heat-insulation coating is prepared from a fluorosilicone modified acrylate emulsion, a styrene-acrylate emulsion, 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate, carboxymethyl cellulose sodium, nonylphenol polyoxyethylene ether, a functional filler, 3, 3-diaminodiphenyl sulfone, polytrifluoropropyl methyl siloxane, methylsilsesquioxane, a functional montmorillonite compound, polyimide microspheres, nano titanium carbide and water. The heat-preservation and heat-insulation coating has good heat-preservation and heat-insulation performance and waterproof performance, and is good in adhesive force and not prone to cracking.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a thermal insulation coating and a preparation method thereof. Background technique [0002] Coatings are a class of polymer materials that are coated on the surface of an object to form a thin film to protect, decorate, or impart heat resistance, heat preservation, and rust resistance. Among them, wall paint can not only decorate the wall with aesthetics, but also protect the wall from aging, cracking, water seepage, corrosion and other phenomena. In addition, the wall coating can also reflect sunlight and play a certain heat insulation effect. Chinese patent CN106830813A discloses a thermal insulation coating, including the following raw materials: ordinary Portland cement, diatomaceous earth, negative ions for construction, urea-formaldehyde resin, basalt fiber, sodium lauryl sulfate, rock wool, expanded perlite , sericite powder, distilled water, dispersant, we...
