Problems solved by technology

The water-based glass transparent heat-insulating coatings currently on the market mainly have the following deficiencies: (1) low hardness and not durable; Because the pigments in the coating have chromophores, and these chromophores have the function of light absorption and energy storage, that is, absorb infrared energy and convert it into heat energy; so the glass transparent heat insulation coatings on the market are difficult to prepare Various colors, the current main variety of glass transparent heat-insulating coating is a single gray; (3) The surface energy of nano-ATO powder is very large, and it is easy to agglomerate, which limits its use

Abstract

The invention discloses an aqueous colored transparent heat insulation coating, and a preparation method and a use method thereof. The aqueous colored transparent heat insulation coating is composed of a water-soluble hydroxy acrylic resin, an aqueous nanometer antimony-doped tin dioxide (ATO) slurry, an aqueous nanometer hydrotalcite slurry, an amino resin, an aqueous color paste, a film forming assistant, deionized water, a dispersant, a wetting agent, a pH adjusting agent, an antifoaming agent, an anti-settling slurry, a thickening agent, an adhesion accelerant and a leveling agent. The preparation method is characterized in that above substances are mixed under specific conditions to obtain the coating. The use method is characterized in that the addition amount of the amino resin is 4-8wt% when the coating is used as a single-component baking varnish; and the addition amount of the amino resin is 0 when the coating is used as a two-component air-dried paint. The coating has the advantages of very good adhesion, high hardness, excellent ageing resistance and good heat insulation effect on the surfaces of glass, plastic films and the like.

Description

technical field [0001] The invention relates to a water-based color transparent heat-insulating coating, a preparation method and a use method of the water-based color transparent heat-insulating coating, especially for glass, plastic film, etc., which need to allow as much visible light to pass through as much as possible and have little effect on indoor lighting and have insulation properties. The preparation method and the application method of the water-based color transparent heat-insulating coating for surfaces such as thermal effects and decorative effects.
