<p>The present invention relates to a transparent coating composition for thermal insulation comprising: a first thermal insulation material which includes a tungsten bronze compound with an average diameter of 1-200 nm; a second thermal insulation material which includes at least one selected from indium tin oxide with an average diameter of 1-200 nm, antimony tin oxide, V_2O_5, and conductive polymers; 20-800 parts by weight of a binder based on 100 parts by weight of the total amount of the first thermal insulation material and the second thermal insulation material; and 100-1,000 parts by weight of a solvent based on 100 parts by weight of the total amount of the first thermal insulation material and the second thermal insulation material, wherein the tungsten bronze compound is a perovskite structure and is represented by chemical formula of A_xBO_3; A includes at least one atom selected from Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba and Ra; B incudes a tungsten (W) atom; O is oxygen; and x satisfies a relation of 0.1<=x<1.0, to a manufacturing method of the transparent coating composition, to a transparent film for thermal insulation manufactured by using the composition, and to a transparent glass for thermal insulation. The present invention is able to obtain the coating composition for thermal insulation which has an excellent blocking rate on a broad range of near infrared rays while having an excellent visible ray penetration rate and exhibits excellent light resistance and thermal resistance.</p> |
