Problems solved by technology

[0004] 1. Using hollow glass microspheres alone to prepare thermal insulation coatings is prone to uneven surface after curing, which affects the adhesion between coatings and substrates, etc.
[0005] 2. The use of airgel to prepare heat insulation materials has a good heat insulation effect, and the airgel density is low, the thermal conductivity is the lowest among all materials, and the light reflectivity is the highest. It is known as the field of heat preservation and heat insulation. The ultimate material, but its thermal stability and aging resistance are poor, especially in areas with high temperature
[0006] 3. Acrylic emulsion or phenolic epoxy resin is used as the basic polymer, and airgel and hollow glass microspheres are used as fillers. Although aerogel and hollow glass microspheres have the characteristics of heat insulation, the basic polymer currently used low thermal stability
