おいても好適な視界が確保可能となる。[Prior Art] Some conventional water-repellent glasses have a glass substrate and a water-repellent layer made of silicone laminated on the surface of the glass substrate. This water-repellent glass is obtained by applying polydimethylsiloxane or the like on the surface of a glass substrate and baking it. Since the water-repellent layer made of silicone imparts water repellency and stain resistance, wind glass and By being used as a glass mirror or the like, it is possible to secure a suitable field of view even in rainy weather.

発され、撥水性の耐久性に欠けるものであった。[Problems to be Solved by the Invention] However, in the conventional water-repellent glass, when baking polydimethylsiloxane or the like, an alkaline component contained in the inside of the glass substrate easily penetrates into the water-repellent layer side, and thus the water-repellent layer is formed. Since the constituent silicone itself does not have sufficient alkali resistance, the alkali component that diffuses after infiltration causes the silicone of the water repellent layer to be hydrolyzed, causing deterioration of the water repellent layer due to long-term use. It was easy. Further, in the conventional water-repellent glass, H + and OH − which have entered from the surface of the water-repellent layer react with the glass substrate when used outdoors by being exposed to sunlight, rain wind, etc., and are eluted by this reaction. Alkali components in the glass substrate invaded the water repellent layer side.
The water-repellent layer was likely to be diffused, and the water-repellent layer was likely to be deteriorated from such a surface. Therefore, in the conventional water-repellent glass, the peeling of the water-repellent layer is induced due to the decrease in the adhesiveness between the glass substrate and the water-repellent layer, and the water-repellent durability is lacking.

Therefore, it is considered that alkali components such as sodium and calcium contained in the glass substrate are prevented from entering the water-repellent layer by the intermediate layer during baking. In addition, even when it is used outdoors by being exposed to sunlight, rain wind, etc., H + and OH − that have penetrated through the water repellent layer from the surface are less likely to enter the glass substrate due to the intermediate layer. It is considered that the reaction with the substrate is suppressed, and the alkali component in the glass substrate that has been partially reacted and eluted is less likely to enter the water-repellent layer by the intermediate layer.

I checked in A. The test was carried out by forming an intermediate layer having a film thickness of 3000 Å on a glass substrate under the same conditions as in Example 1 and then annealing this for 20 minutes at 250 ° C. Results are shown in FIG.

The alkaline component is 1 from the surface of the intermediate layer that contacts the glass substrate.
It can be seen that the depth of invasion is 000Å. Therefore, in the glass substrate having the intermediate layer, it is understood that the alkali component contained in the glass substrate is prevented from moving by the intermediate layer, and the invasion into the water repellent layer can be effectively prevented. Further, in order to eliminate the influence of the alkaline component, the thickness of the intermediate layer is 10
It can be seen that a value of 00Å or more is sufficient.

Then, the change in the contact angle of the water droplet with respect to the water-repellent layer after irradiation for a predetermined time was measured, and the degree of decrease in water repellency was examined.

It can be seen that the contact angle is reduced to half after more than 00 hours. On the other hand, it can be seen that in Example 1, the degree of decrease in contact angle is very small even after irradiation for 1500 hours. The results of C and Reference Example 2 were similar to those of Example 1. From this result, the ultraviolet exposure test (we
It is clear that the deterioration of the water-repellent layer due to t) is promoted, and the water-repellent glass of this D is subjected to the ultraviolet exposure test (wet).
It can be seen that the deterioration of the water-repellent layer due to is small. The reason for this is that in the water-repellent glass of Comparative Example, the alkaline component was likely to invade the water-repellent layer during baking and by the ultraviolet exposure test (wet), whereas in D, the alkaline component was also easily incorporated into the water-repellent layer. It is thought that this was because it was difficult to invade. Therefore, the water-repellent glass of D is less likely to cause a decrease in the adhesiveness between the glass substrate and the water-repellent layer and peeling of the water-repellent layer, even when used for a long time, as compared with the comparative example.
It can be seen that it has water repellency with excellent durability.
