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

Abstract

The invention relates to an antiaging nano composite thermal-insulation paint and a preparation method thereof, belonging to the technical field of a paint and a preparation method thereof. The paint is composed of the following components in parts by mass: 100 parts of base material, 0.7-1.2 parts of TiO2 / ZnO nano composite powder and 1.5-2.2 parts of nano ATO (antimony tin oxide) powder. The base material comprises the following components in parts by weight: 100 parts of monomer, 0.5-1.5 parts of initiator, 1.1-1.5 parts of activating agent and 1.3-1.8 parts of emulsifier. The monomer is composed of acrylic acid and n-butyl acrylate in a volume ratio of 2:3, the initiator is sodium dodecyl benzene sulfonate, and the emulsifier is OP-10. The ratio of TiO2 to ZnO in the TiO2 / ZnO nano composite powder is 10:(5.8-7), and the particle size range of the TiO2 / ZnO nano composite powder is 40-70nm. The particle size range of the nano ATO powder is 20-70nm. The paint has the advantages of favorable visible light transmittance and favorable ultraviolet shielding function, and enhances the aging resistance of the coating.

Background technique [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 exposed to ultraviolet light during use, 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. [0003] Therefore, there is a very urgent market demand for research and exploration of glass thermal insulation coatings that can achieve high thermal insulation performance and weather resistance under the premise of high transparency....
