Abstract

The invention relates to the technical field of preparation of heat-insulating films, and discloses a film preparation process based on a reflective nano ceramic heat-insulating film. According to the invention, organic silicon resin, titanium dioxide powder, an ultraviolet absorbent, ceramic powder and the like are used as raw materials for mixed reaction. The invention further discloses the heat insulation film based on the reflection type nano ceramic and a spraying device. Wherein the selected titanium dioxide has a relatively high refractive index, so that the light scattering capability of the nano ceramic heat insulation film is improved, and the transparency and the heat insulation property of the coating are improved. 2-hydroxy-4-n-octyloxybenzophenone and 2 '-(2'-hydroxy-3 '-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole are used as ultraviolet absorbents, so that the purpose of blocking ultraviolet rays is achieved. And the nano ceramic powder has a nano-scale size, and has the advantages of good chemical stability and strong heat resistance.

Description

technical field [0001] The invention relates to the technical field of heat insulating films, in particular to a reflective nano-ceramic heat insulating film and a film-making process thereof. Background technique [0002] With the massive use of thermal insulation films in automobiles and buildings, the application of thermal insulation films is very common and the market demand is strong. However, the existing thermal insulation film preparation process has problems such as insufficient production capacity and serious pollution, which is contrary to the scale of market demand. [0003] Among them, the ceramic film itself has the properties of light weight, high strength, high hardness, high temperature resistance and corrosion resistance. The thermal insulation film prepared from nano-ceramics not only has high visible light transmittance. At the same time, it can provide high reflection of infrared rays and far infrared rays, and is widely used in construction and autom...
