Abstract

The invention relates to a high-bonding-strength mildew-proof heat-insulation and -preservation coating which is prepared from the following components in parts by weight: 40-50 parts of water, 0.5-0.6 parts of hydroxyethyl cellulose, 0.5-0.6 parts of an inorganic thixotropic thickening agent, 0.05-0.1 parts of an aqueous multifunctional auxiliary agent, 0.7-0.8 parts of a dispersing agent, 0.05-0.1 part of a wetting agent, 20-25 parts of 500 to 800-mesh coarse whiting, 8-12 parts of aerogel, 16-20 parts of an emulsion, 0.8-1.2 parts of an antifreeze agent, 0.6-0.7 part of a coalescing agent,0.5-0.8 part of a defoaming agent and 0.2-0.5 part of an anti-corrosion and anti-mildew agent. The coating disclosed by the invention not only has a heat insulation effect of a superior product, but also has a heat conductivity coefficient of less than 0.08 W/(m.K) and has the advantages of high bonding strength, high-efficiency mildew prevention and bacteria prevention effects; the paint film hasexcellent performance and good hand feeling; not only are heat conduction and heat radiation blocked and heat conduction reduced, but also the construction performance of the coating is improved.

Description

technical field [0001] The invention relates to the field of functional coatings, in particular to an anti-mildew and heat-insulating coating with high bonding strength and a preparation method thereof. Background technique [0002] my country's energy resources are seriously in short supply, and it is imminent to save energy and reduce consumption through science and technology. Building energy saving is an important aspect of scientific and technological energy saving. At present, external insulation structures are generally adopted in the market for building energy conservation. The building insulation materials used include rock wool, glass wool, polystyrene plastics, polyurethane foam plastics, and polyethylene plastics to reduce the heat transfer coefficient of external walls. The use of the above materials in building exterior walls has disadvantages such as the internal structure collapses when exposed to water, resulting in a sharp drop in thermal insulation effect...
