Abstract

The invention discloses heat insulation inorganic coating and a preparation method thereof. The coating is prepared by combining the super heat insulation function of an aerogel material with the specific water resistant and flame retardant functions of a magnesium phosphate cement material (MPC). Compared with the existing organic polymer aerogel composite coating and ordinary silicate aerogel composite coating, the inorganic waterborne heat insulation coating disclosed by the invention has the advantages of low heat conductivity, good water resistance, good flame retardant property and flame resistance, environmental protection and energy conservation. The heat insulation inorganic coating disclosed by the invention can be widely applied to a variety of fields, such as heat insulation of internal and external walls and roof surfaces of such public buildings as residential buildings, schools, hospitals, factory buildings and the like, thermal expansion damage prevention and protection of such large-volume buildings or facilities as bridges, dams and the like, and protection of top sunlight surfaces of ships, trains and buses.

Description

technical field [0001] The invention relates to a thermal insulation coating and a preparation method thereof, in particular to an inorganic water-based thermal insulation coating combined with airgel powder and magnesium phosphate cement (MPC) and a preparation method thereof. Background technique [0002] SiO 2 Airgel is a kind of highly dispersed solid material with nano-scale particles aggregated to form a nano-porous network structure, and the pores are filled with a gaseous dispersion medium. Because of its nano-porous structure, low density, low dielectric constant, Low thermal conductivity, high porosity, high specific surface area and other characteristics, showing unique properties in mechanics, acoustics, heat, optics and other aspects, in aerospace, military, petroleum, chemical, mineral, communication, medical, building materials, electronics, metallurgy It has extensive and huge application value in many fields, and is called "the magic material that changes t...
