Problems solved by technology

[0002] At present, transparent heat-insulating glass coatings basically use organic film-forming substances. During use, they will gradually age, yellow, and pulverize after being irradiated by ultraviolet rays, so their weather resistance is not ideal.
The thermal insulation functional materials basically use ATO or ITO near-infrared short-wave blocking nano-materials to spread the liquid, but these two materials can only block the long-wave part of the near-infrared, that is to say, they can only block part of the solar heat radiation. Not ideal, its shading coefficient is basically around 0.75

Description

technical field [0001] The invention belongs to the technical field of coatings and preparation methods thereof. Background technique [0002] At present, the transparent insulating glass coating basically uses organic film-forming substances. During the use process, after being irradiated by ultraviolet rays, it will gradually age, turn yellow, and chalk, so its weather resistance is not ideal. The thermal insulation functional material basically uses ATO or ITO near-infrared short-wave blocking nanomaterials to distribute liquid, but these two materials can only block the long-wave part of the near-infrared, that is to say, only a part of the solar thermal radiation can be blocked, and the blocking effect Not ideal, its shading coefficient is basically around 0.75. [0003] Therefore, research and exploration of glass thermal insulation coatings that can achieve both high thermal insulation performance and weather resistance under the premise of satisfying high transparen...
