Problems solved by technology

[0005] At present, the thermal insulation coatings on the market are mixed, and they are only titled thermal insulation coatings. The heat insulation does not meet the thermal insulation standards of the Ministry of Housing and Urban-Rural Development, and they are basically organic latex paints, which have poor weather resistance, short service life, and easy chalking. melting and cracking

Abstract

The invention provides a water-based heat-insulating inorganic coating and a preparation method thereof. The water-based heat-insulating inorganic coating is prepared from the following components inparts by mass: 300-400 parts of water, 1-5 parts of cellulose ether, 1-5 parts of attapulgite, 1-5 parts of a wetting agent, 1-5 parts of a dispersant, 10-20 parts of glyoxal, 1-5 parts of a bactericide, 1-5 parts of an inorganic coating multifunctional auxiliary agent, 1-5 parts of an antifoaming agent, 50-100 parts of barium sulfate, 150-200 parts of titanium dioxide, 50-100 parts of calcined kaolin, 100-150 parts of emission heat insulation powder, 150-250 parts of pure acrylic emulsion, 50-150 parts of potassium silicate, 50-150 parts of silica sol, 10-15 parts of a coalescing agent and 1-5 parts of a thickening agent. The water-based heat-insulating inorganic coating provided by the invention meets the requirements of liquid inorganic coatings published by the Ministry of Housing andUrban-Rural Development of the People's Republic of China (liquid inorganic coatings for inner and outer walls of buildings) in 2019, meets the radionuclide class A standard of indoor decoration materials, and has a heat-insulating effect meeting the heat-insulating standard of the Ministry of Housing and Urban-Rural Development.

Description

technical field [0001] The invention relates to the technical field of water-based inorganic coatings, in particular to a water-based heat-insulating inorganic coating and a preparation method thereof. Background technique [0002] Inorganic coatings have not been clearly defined. According to the form, they are divided into powder type and liquid type. According to the habit of naming coatings, they are generally classified according to the main film-forming substances. Therefore, inorganic coatings usually refer to inorganic materials as the main film-forming substances. or a type of adhesive coating. On December 19, 2019, the Ministry of Housing and Urban-Rural Development of the People's Republic of China issued a revised draft (Liquid Inorganic Coatings for Building Interior and Exterior Walls), which clearly stipulates that the main binders of liquid inorganic coatings are alkali metal silicates and silica sols. , can add a small amount of high molecular organic matte...
