Abstract

The invention relates to a water-based nano heat insulation material for a building and a preparation method thereof. The water-based nano heat insulation material is composed of a porous water-based nano SiO2 suspension emulsion, inorganic nano TiO2, inorganic nano bismuth chloride oxide, hollow glass micro spheres, an inorganic ultramicro material, a functional auxiliary, a fire retardant and deionized water. Compared with the traditional material, a water-based nano heat insulation material coating prepared by the water-based nano heat insulation material provided by the invention is obviously better than the traditional heat insulation plate in heat conductivity coefficient, and the water-based nano heat insulation material provided by the invention has excellent fire resistance and discharges no toxic substance, so that the water-based nano heat insulation material provided by the invention is a novel environment-friendly building heat insulation material. By adopting the water-based nano heat insulation material provided by the invention, a coating process is adopted, a heat insulation technical index can be adjusted according to different building thermotechnical climatic regions, wall structures, thicknesses and technical requirements, a working procedure can be simplified, and good construction effect and the best cost performance of a project are achieved.

Description

【Technical field】 [0001] The invention belongs to the technical field of water-based nanometer building thermal insulation materials. More specifically, the present invention relates to a water-based nano thermal insulation material for building composited by inorganic nanomaterials, glass hollow microspheres, inorganic ultrafine materials and acrylic emulsion. 【Background technique】 [0002] At present, my country's high-energy buildings account for more than 95% of the total building area, and the heating energy consumption per unit area is equivalent to 2 to 3 times that of developed countries with similar climate conditions. Building energy consumption is huge. Therefore, Order No. 143 of the Ministry of Construction of the People's Republic of China "Civil Building Energy Conservation Management Regulations" stipulates that in the planning, design, construction and use of our country's urban construction, building energy conservation standards must be implemented, and b...
