The invention discloses a water-based color transparent heat-insulating coating, a preparation method and a use method thereof. The water-based color transparent heat-insulating coating is composed of water-soluble hydroxy acrylic resin, water-based nano-antimony-doped tin dioxide (ATO) slurry, water-based nano-hydrotalcite slurry, Amino resin, water-based colorant, film-forming aid, deionized water, dispersant, wetting agent, PH regulator, defoamer, anti-settling agent, thickener, adhesion promoter, leveling agent. The preparation method is as follows: the above-mentioned substances are mixed successively under specific conditions to obtain it. The method of use is: when used as a one-component baking varnish, the amount of amino resin added is 4-8% (by weight). When used as a two-component self-drying paint, the amount of amino resin added is 0. The paint has good adhesion on surfaces such as glass and plastic films, and has high hardness, excellent aging resistance and good heat insulation effect.
