【発明の詳細な説明】
［産業上の利用分野コ
この発明は水滴付着１こよる曇りを生じない防曇ガラス
ＩＣ開する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides an anti-fog glass IC which does not cause fogging due to adhesion of water droplets.
［従来の技術］
ガラスに発生する曇りの現象は、空気中の水蒸気がガラ
スとの温度差のために露結して、ガラスの表面に微小な
水滴が多量に発生し、この微小な水滴が光を乱反射した
り、複雑に屈折させることによっておこる現象である。[Prior art] The phenomenon of fogging that occurs on glass is caused by water vapor in the air condensing due to the temperature difference between the glass and the glass, resulting in a large number of minute water droplets being generated on the surface of the glass. This is a phenomenon that occurs when light is diffusely reflected or refracted in a complicated manner.

会社］しかし、このような防曇液は蒸発したり、拭取ら
れたりして、効果を長く維持することが困難な事情１こ
あった。In order to prevent this fogging, conventionally, an antifogging liquid such as a water-friendly surfactant was applied to the surface of the glass to reduce the surface tension and prevent the formation of water droplets. [Patent No. 1360706 (Anti-fog agent) Kurasawa Optical Industry Co., Ltd.] However, there is one reason why such an anti-fog liquid evaporates or is wiped off, making it difficult to maintain its effectiveness for a long time. .
［発明が解決しようとする問題点］

曇ガラスを提供することを目的とする。[Problems to be Solved by the Invention] This invention solves the problem of using a material that does not require special measures such as the above-mentioned anti-fogging solution, that is, for example, glasses, which cause fogging due to the properties of the material itself. Our aim is to provide anti-fog glass that never becomes cloudy.

機ヒ１ろ。[Means and effects for solving the problems] The present invention comprises an anti-fog glass by mixing a niobium-based substance containing niobium into a glass base material and melting the mixture by heating.
Kihi 1ro.
このように構成することにより、母材は低膨張で温度変
化の少ない材料となり、そのため微小なレンズ状の水滴
発生を防止できる。With this configuration, the base material is made of a material with low expansion and little temperature change, thereby preventing the generation of minute lens-shaped water droplets.
［実施例コ 以下実施例１こもとすいて、この発明を説明する。[Example code] The present invention will be described below with reference to Example 1.

り具合を、優良可で評価した結果をまとめたものである
。The table below shows the degree of cloudiness when glass is used as the base material and niobium-based substances containing niobium are mixed and melted at 1,400 degrees Celsius to 1,600 degrees Celsius in various proportions. This is a summary of the results of the evaluation as good or fair.
混合割合は母材に対する重量比を係で表わしている。な
お、評価の優、良、可は
優 防曇効果の特に優良である場合
良 これが良好である場合
可 実用上差し使えない程度の防曇効果のある場合
の各場合である。The mixing ratio is expressed as a weight ratio to the base material. The ratings of Excellent, Good, and Fair are: Good when the anti-fogging effect is particularly excellent; Acceptable when the anti-fogging effect is good; and Acceptable when the anti-fogging effect is of such an extent that it cannot be used for practical purposes.
同辰の実験結果によれば、ニオブを含むニオブ系物質の
混合量は１優乃至３０チ程度のものが最も防止曇作用が
あることかわかる。According to the experimental results of the same group, it can be seen that the amount of the niobium-based substance containing niobium mixed in the range of 1 to 30% has the best antifogging effect.
