Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a so-called wire-filled sheet glass, which is reinforced by inserting wires in the shape of a mesh or horizontal lines within the glass.

[Conventional technology]

Wire-containing sheet glass is made by making a cut of a predetermined size on the glass surface and applying bending force to cut it together with the wire. (hereinafter referred to as the "wire end face") is exposed.

Therefore, if the end of the wire is exposed to moisture, rainwater, etc., the wire will rust, and the rust will progress to the inside of the glass, damaging its appearance. It had the disadvantage that it cracked (referred to as rust cracking or heat cracking).

The above-mentioned drawbacks are noticeable in plate glass for louvers, which is used with the end surfaces of the glass exposed.

In other words, when it comes to plate glass used as the vanes of so-called louver sashes, which measure ventilation and lighting by rotating multiple vanes at the same time at a required angle by operating a handle, etc., from the viewpoint of lighting performance and aesthetics. Since the end face of the glass is used without being coated, the end face of the wire is exposed, and the above-mentioned drawbacks become conspicuous.

As a solution to this drawback, JP-A-55-
Techniques such as those disclosed in Publication No. 3335 are known. According to these methods, a concave portion is formed in the end surface of the sheet glass where the wire end surface is exposed, and a thermoplastic rubber material is applied as a watertight material to the concave portion while being pressurized by a special discharge gun. Furthermore, according to Japanese Patent Application Laid-Open No. 52-44813, chlorinated rubber or the like, which dries at room temperature and cures at room temperature, is applied to the end face of a wire-containing plate glass so as to cover the end of the wire, thereby imparting a rust-preventing function. .

[Problem to be Solved by the Invention] However, in the above-mentioned conventional technology, the former, that is, the technology described in Japanese Patent Application Laid-open No. 55-3335, requires a jig such as a dedicated discharge gun for applying the rubber material. Become. In addition, the watertight material is made of a single layer, and if it is made of a rubber material that can close the minute cracks on the glass edge, it will have poor durability, and if the strength is increased enough, it will not be able to close the minute cracks. Moreover, the latter, namely, JP-A-52-44813
The technique disclosed in the publication had problems such as the formed anti-rust coating was thin and weak, and the anti-rust function did not last long.

The present invention was made in order to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a wire-filled plate glass that can completely prevent wire rust and maintain watertightness for a long time.

[Means to solve the problem]

In order to achieve the above object, the present invention forms a recess on the end face of a wire-filled plate glass, with the wire end face being the deepest part, and a layer formed by applying liquid silicone resin to the surface of the recess and the wire end face. The concave portion is provided with a watertight material consisting of two layers: and a layer formed by filling a rubber-like silicone resin so as to cover the liquid silicone resin layer.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the structure of the present invention will be explained below by taking a glass plate for a louver shown in the drawings as an example.

As shown in FIG. 1, a roughly U-shaped recess 3 is formed with a diamond wheel on the glass end faces (left and right end faces) where the end faces of the wire 2 of the louver glass plate 1 are exposed, with the wire end faces being the deepest part. At this time, fine cracks may occur in the glass around the end face of the wire, and the cracks cannot be completely closed only by filling with the rubbery silicone resin. If this crack is left untreated, the wire will rust due to the intrusion of moisture, rainwater, etc. due to capillary action. Therefore, in the present invention, as shown in FIG. 1, liquid silicone resin 4 (50% toluene solution) is applied to the recess 3 formed in the lined louver plate glass 1, and after drying, rubber-like silicone resin 5 is filled. However, it is finished almost flush with the end surface of the glass. In other words, a double watertight material 6 is provided within the recess 3.

Further, in the wired louver plate glass 7 shown in FIG. 2, a liquid silicone resin 4 is applied to the concave portion 3, and after drying, a rubbery silicone resin 5 is filled to form a double watertight material 6. .

The silicone resin used as a watertight material can be obtained in various forms such as resin, rubber, and liquid.
Excellent heat resistance and little change in physical properties due to temperature.
Highly moisture resistant, water resistant, and highly water repellent. Strong adhesion. Highly flexible and highly elastic. Because of these characteristics, the application and filling work of the watertight material 6 is easy, the resin layer can be formed thickly, and the adhesive property is good.
It is difficult to peel off and can prevent wire rust, rust cracking, and heat cracking. Moreover, the transparency as a plate glass for a louver is not impaired.

〔Effect of the invention〕

As explained above, in the present invention, it is possible to prevent wire rust and prevent so-called rust cracking and thermal cracking of glass caused by wire rust.

In addition, since the watertight material of the present invention has a double structure, the liquid silicone resin can penetrate into the fine cracks that occur in the glass around the end of the wire, and the rust of the wire is better than when only rubbery silicone resin is filled. can be more completely prevented. By covering the layer of liquid silicone resin with rubbery silicone resin, a special effect is achieved in that durability can be increased.
