Solvent type vehicle heat insulation coating

The invention discloses a solvent type vehicle heat insulation coating which comprises the following components in parts by weight: 3-4 parts of nano dispersion liquid, 35-40 parts of color paste, 50-60 parts of film-forming resin, 0.3-1 part of an anti-sagging aid, 5-7 parts of a solvent, 0.5-1.5 parts of a flatting agent and 0-0.5 part of a dispersing agent, wherein the nano dispersion liquid is a dispersion liquid obtained by dispersing nano ATO and/or ITO powder treated by amino siloxane in hydroxyl acrylic resin or hydroxyl polyester resin; dispersion resin of the nano dispersion liquid and the color paste is hydroxyl acrylic resin or hydroxyl polyester resin, and the hydroxyl content is 1.0%-3.0%; and the film-forming resin is hydroxyl acrylic resin or hydroxyl polyester resin with the hydroxyl content of 3.0-4.5%. The coating disclosed by the invention is excellent in comprehensive properties of gloss, weather resistance and heat insulation, and can be used as vehicle finishing paint or finishing varni
