固着させることは非常に難しい。However, these are resin-based coating agents and do not have durability comparable to glass. For example, in water-repellent glass for automobiles, 1
Recoating is required once every two years. Therefore, if the glass itself has water and oil repellency functions, the antifouling properties of automobiles, train windows, window glass, sanitary ware, tableware, and the like can be maintained, and application development can be expected. In order to have antifouling properties and not detract from aesthetics, there are many conceivable transparent resin materials having a material surface coated with a resin-based water-repellent material or having water-repellent properties.
However, both have problems in durability and wear resistance. In addition, glass having water repellency (such as fluoride glass alone) is quite uneasy and it is very difficult to adhere to the surface of the member because it evaporates when the heated surface is used for the surface coating. .

わかる。FIG. 2 is a diagram summarizing the contact angles of commonly used members with water and fatty acids. It can be seen that commercially available inorganic materials such as glass, tiles and enamels have low contact angles with water and fatty acids, whereas organic materials such as fluororesins tend to have high contact angles with water and fatty acids. However, the newly developed fluoride glass and oxide glass with partial fluoride (oxyhalide glass) have a high contact angle with water and fatty acids, despite being inorganic materials, and exhibit a property similar to that of organic materials. You can see that. From this, it is understood that the member made of the present composition has the antifouling property of an organic substance and realizes the high durability of an inorganic material.
