した酸化錫から゛なる酸化物薄膜が知られている。[Prior Art] In recent years, double-glazed windows with a dry air layer sandwiched between them have been used for architectural window glasses in order to reduce the heating load. In addition, in order to further reduce the heating load by reflecting infrared rays from indoor heating using this double-glazed window glass, a multilayer structure consisting of a metal film, a gold gI4 nitride film, and a dielectric film is used on the glass. There are known thin films formed by physical methods such as sputtering. However, since this glass is expensive to manufacture and has relatively low durability, there is a desire for an inexpensive glass that has the same functionality. A spray method in which a liquid raw material is sprayed is known as a thin film forming method that can provide this low-cost and highly durable coating. There are many types of coatings obtained by the spray method, but examples of coatings with high infrared reflectance include C4H9SnCl3, N II a F s H2
An oxide thin film made of tin oxide mainly using fluorine and chlorine as dopant sources is known, which is obtained by spraying a liquid raw material consisting of 0s and CI (30H).

た。[Problems to be Solved by the Invention] However, infrared reflective glass obtained by forming a thin film mainly composed of tin oxide doped with fluorine and chlorine on glass by a spray method has the following problems. there were. That is, the emissivity indicating infrared reflection performance was not very low, and sufficient heat ray reflection performance was not obtained.

係があり、膜付温度を高くすれば、低い放射率は得られ

し、商品特性を著しくおとしめるという問題もあった。Of course, there is a certain relationship between the spray coating temperature and the emissivity, and if the coating temperature is increased, a lower emissivity can be obtained, but on the other hand, the flatness of the glass deteriorates rapidly during heating. There was also the problem that the characteristics of the product were significantly degraded.

In the present invention, in order to form a thin film mainly composed of tin oxide with fluorine and chlorine as dopant sources on the surface of a glass plate,
A spray method is used in which a prepared raw material is sprayed in the form of fine droplets onto the surface of a glass plate heated to a temperature above 0.5C to form a thin film through a thermal decomposition oxidation reaction. Conventionally, C4H95 was used to form a thin film mainly composed of tin oxide on the surface of a glass plate.

Or use CF3COOH and use phthyl alcohol (C4H90H) or ethyl acetate CH3CO0 as the solvent.
C2Hs is used as a raw material liquid by dissolving it in water or the like. As for the spraying method, a liquid obtained by mixing each component in advance may be sprayed in the form of minute droplets, or each component may be separately made into droplets and sprayed and reacted at the same time.
