SOLAR-HEAT-BLOCKING COATING SOLUTION AND SOLAR-HEAT-BLOCKING COATED GLASS USING THE SAME

摘要

The present invention relates to a solar-heat-blocking coating solution for blocking solar heat and to solar-heat-blocking coated glass obtained by coating the same directly onto glass. More specifically, the invention relates to a solar-heat-blocking coating solution resulting from the mixing of: a sol-gel organic-inorganic composite binder solution comprising a mixture of a solvent and a sol-gel organic-inorganic composite resin made by mixing an acrylic polymer resin and a sol-gel silicate which constitutes an inorganic ceramic; and a nano metal oxide ink comprising a nano metal oxide, a dispersant able to effectively disperse the nano metal oxide, and a solvent; and the invention relates to solar-heat-blocking coated glass using the coating solution. Also, the solar-heat-blocking coated glass according to the present invention has the advantage that it provides solar-heat-blocking coated glass for performing a solar-heat-blocking function, in which the coating solution is not thick and which stays transparent and is outstanding in terms of visible light transmittance, the percentage of infrared blocked, hardness, weather resistance, solvent resistance, adhesiveness and the like, and which entails coating directly onto glass other than in the form of a film as extensively used in the prior art.
