を提供することができるようになった。Therefore, in recent years, a window called a module assembly window (hereinafter referred to as MAW) in which a synthetic resin frame is integrally formed around a glass plate has become widespread. In this MAW, after applying an adhesive agent to the peripheral portion of the glass plate in advance, the solvent is air-dried, the glass plate is heated if necessary, the glass plate is mounted on a mold, and the synthetic resin is made by injection molding. It is manufactured by integrally molding the frame body, and since the resin frame body is integrally molded on the glass plate, the number of assembly steps is small, it is rich in watertightness and adhesion, and it can provide an excellent appearance. I can do it now.

欠点を有していた。In the conventional MAW manufacturing method, when the resin is injected into the mold, the air pressure in the mold increases due to the inflow of the resin. It was necessary to inject at a pressure of more than 500 kgf / cm 2 . However, when performing injection by this injection pressure, the stress applied to the glass plate is large, especially when the glass plate is a glass plate that is bent or easily broken such as laminated glass, when injecting resin,
Alternatively, it has a drawback that the glass is easily broken after injection.

しまうため外観の良好な樹脂枠体が得られなかった。On the contrary, when the injection pressure is reduced so that the laminated glass is not broken, the resin does not weld well at the weld portion where the resin flowing in from a plurality of points is connected, and a joint called a weld line is formed on the finished resin frame. However, the resin frame body having a good appearance cannot be obtained because the resin remains or the resin frame body is sinked.

A frame body that is mounted so as to sandwich the portion, and injects a resin material into a cavity space formed by the inner wall of the mold and the peripheral portion of the glass plate to integrally form a resin frame body in the peripheral portion of the glass plate. In the method for producing a glass plate with a frame, the glass plate having a planar compressive stress formed at the peripheral edge thereof is used, and a method for manufacturing a glass plate with a frame is provided.

を指す。A compressive stress is formed on the surface of the peripheral edge of the glass plate in the present invention, and this stress is what is called so-called peripheral strengthening of the glass plate. It is the stress detected by. In addition, as the region where the compressive stress is formed,
In the direction from the end face of the glass plate toward the inner peripheral side, it refers to the region up to the neutral point where the compressive stress and the tensile stress cancel each other out.

ングで突き上げて、徐冷ゾーンに保持するものである。The method for forming such a compressive stress is not particularly limited, but when the glass plate heated to the softening point or higher is gradually cooled, the ring for slow cooling is provided on the inner peripheral side of the end face of the glass plate. It is preferable that the glass plate is held in the slow cooling zone by pushing up with, and strengthens the periphery of the glass plate, that is, forms a plane compressive stress in the peripheral portion of the glass plate (this method is called push up slow cooling). Particularly, when the glass plate is bent by a bending ring die and then gradually cooled, the inner peripheral side of the bending ring die is pushed up by the annealing ring and held in the annealing zone. is there.

上記の圧縮応力を形成する方法としては突き上げ徐冷が
好ましい。The glass plate in the present invention is for strengthening the peripheral edge portion so that the peripheral edge portion is sandwiched by the mold, and it is necessary to strengthen a predetermined area (described later).
Moreover, since the portion where the glass plate is sandwiched by the mold is usually about several tens of mm from the end face of the glass plate, it is sufficient if the region including the sandwiched portion is substantially strengthened. . Therefore, since it is easy to strengthen the periphery over such a wide area,
As a method of forming the above-mentioned compressive stress, push-up gradual cooling is preferable.

０ｍｍ程内周側とすることによって、容易に所定の応力
領域を得ることができる。The region of compressive stress formed in the glass plate depends on the size of the mold and the position at which the glass plate is clamped, and depending on the above-mentioned method of strengthening the periphery. A region not exceeding 150 mm is desirable, and a region not exceeding 100 mm is more desirable. This region can be easily achieved by, for example, the above-described stress forming method. The contact holding position of the ring for pushing up the glass plate in the slow cooling zone with the glass plate is slightly inside the region of the compressive stress to be formed, for example, 3
By setting the inner peripheral side to be about 0 mm, a predetermined stress region can be easily obtained.

とが好ましい。Further, the stress region may be formed along the entire circumference of the glass plate or along one side or several sides of the glass plate, and is preferably formed depending on the place where the frame body is formed. The formation of stress on a part of the entire circumference of the glass plate can be performed by partially blowing cooling air or by arranging a plate or the like for controlling heat radiation at a predetermined position, but the work is simple and easy. Considering that the glass plate can be more reliably prevented from cracking, it is preferable that the stress is formed over the entire circumference of the glass plate.

Plane tensile stress is formed on the inner peripheral side of the region where the compressive stress is formed, and the maximum value thereof may be such a size that the crack does not run on its own when the crack enters the glass plate, If it is about 100 kgf / cm 2 or less, it can be sufficiently applied to a glass plate for a vehicle window.

値をできるだけ小さくすることができる。In particular, since the present invention clamps the peripheral portion of the glass plate in the mold, it is preferable that the region clamped by the mold be strengthened substantially uniformly. For example, from the end face of the glass plate. When the plane compressive stress is formed in the area of 100 mm, the stress value is almost the same from the end face to the vicinity of 100 mm, the neutral point is located 100 mm from the end face, and the plane tensile stress on the inner peripheral side is as small as possible. It is preferably a value. That is, if the plane tensile stress value is too large, when the glass plate is cracked as described above, the crack will be self-propelled and unsuitable as a glass plate for a vehicle window. In this case, when the magnitude and area of the plane compressive stress are the above-mentioned values, the plane tensile stress is formed over a wide area on the inner peripheral side of the neutral point, and thus the value can be minimized.
