Abstract

The invention discloses a heat-insulation coating applied to building exterior walls. The heat-insulation coating is prepared from the following raw materials: 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, poly(trifluoropropyl)methylsiloxane, methyl silsesquioxane, montmorillonite, nanometer titanium carbide and water. According to the invention, the above raw materials have a synergistic effect, so the heat insulation performance of an exterior wall for a building is improved; and meanwhile, the coating has good water resistance, and the service life of the coating is prolonged.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a thermal insulation coating applied to building exterior walls. Background technique [0002] Coating refers to coating on the surface of the object to be decorated, and can form a firm, dense and complete coating film with the object to be decorated. With the rapid development of science and technology, the requirements for coatings are getting higher and higher, making them multi-functional to meet the needs of society. [0003] In the season of hot summer and cold winter, the increase or decrease of the outer surface of the building with the increase of temperature will definitely increase or decrease the temperature inside the object, which seriously affects people's quality of life. At the same time, due to the weather The reasons for this cause air conditioners, refrigerators and other devices to be used in large quantities, further causing the serious environmental prob...
