。TECHNICAL FIELD 1 The present invention relates to a method for manufacturing laminated glass in which a plurality of temporary laths are bonded together via an adhesive. [Background technology] Conventionally, a hot-melt film made of a hot-melt adhesive is sandwiched between glass plates, and the glass plates are heated and pressurized under vacuum to make them adhere to each other. was. However, because the hot melt film has a smooth surface, even if the pressure is reduced to near vacuum, if the periphery of the hot melt film adheres to the glass plate, the glass plate and the hot melt film will be damaged. The air between the glass plate and the hot melt film is no longer evacuated and remains in the gap between the glass plate and the hot melt film, forming bubbles.
There is a problem in that the lamination deteriorates the appearance of the lath and lowers its quality. In addition, the hot melt film used was larger than the glass plate, and after being sandwiched between the glass plates, the portion that protruded from the glass plate was cut off, resulting in waste material and reducing the yield rate of the hot melt adhesive. It was bad.

ある。The method for manufacturing laminated glass of the present invention involves preheating a powdered hot-melt adhesive resin 2 powder-coated on a glass plate 1 to form a porous layer 3 of adhesive BW 2; Lay another glass plate 1 on top of the glass plate 1 and apply pre-gluing adhesive 2 under vacuum pressure.
This method is characterized in that the glass plates are bonded together by one space. Therefore, the adhesive I (
Since the resin 2 is formed in the porous layer 3, when the glass plates 1 are closely bonded together, the voids in the porous layer 3 act as deaeration holes, and the gaps between the glass plates 1 and the glass plates 1 are removed. The air between the glass plates 1 and the hot melt adhesive 2 can be reliably discharged to the outside between the glass plates 1. In addition, adhesive resin 2
Since the adhesive resin 2 is in the form of a powder, the excess adhesive resin 2 coated on the glass plate 1 can be easily recovered and reused. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. What is shown in FIG. 1 is a manufacturing process for laminated glass, in which a lath plate 1 is conveyed by a roller conveyor 4. Above the roller conveyor 4, there is a particle size of 0.1 to 0.1511Iff.
A coater 5 is provided which supplies hot melt adhesive resin 2 in the form of a powder. 2 is Figure 1 (,) and! ! As shown in Fig. 2 (,), it is applied to a certain thickness on the glass plate 1,
The excess adhesive FJ (fat 2) is collected into a collection tray (not shown) placed below the row 2 conveyor 4 and reused. At this time, the adhesive resin 2 on the surface of the lath board 1 is preheated to form a spongy porous layer 3 as shown in FIG. 2 (L,). After this, another glass plate 1 is placed on top of the glass plate 1 from above the porous layer 3 of adhesive U (oil 2), and both glass plates 1 are bonded together under vacuum. The glass plates 1 and 2' are bonded together with the adhesive resin 2'c. At this time, the glass plates 1
The air between the layers is discharged to the outside through the voids 7 in the porous layer 3, thereby preventing air bubbles from forming inside the laminated glass. What is shown in FIGS. 3(a) and 3(b) is an example of a pond according to the present invention.
Powder spraying with a built-in heater 8 for preheating sprays powder adhesive resin 2 onto the glass plate 1 with air 10 from a machine 9, and powder spraying sprays adhesive resin 2 from a rock 9. At the same time, the adhesive resin 2 is preheated by the heater 8. In this way, since the adhesive resin 2 sprayed onto the glass plate 1 is sprayed in a preheated state, it adheres to the glass plate 1 at the same time.
As shown in Figure t54, it is welded to the glass plate 1 to form the porous layer 3. Thereafter, when another glass plate 1 is placed on top of this glass plate 1, the air inside is discharged to the outside through the voids 7 of the porous layer 3, producing a laminated glass that does not contain air bubbles.

る。As described above, the present invention is based on adhesive U sandwiched between glass plates.
(Since the fat is formed in the porous layer, when the glass plates are closely bonded together, the voids in the porous layer act as deaeration holes, allowing the hot melt adhesive to flow between the glass plates and between the glass plates and the hot melt adhesive. This has the advantage that the air between the glass plates can be reliably discharged to the outside between the glass plates, and high-quality laminated glass that does not contain air bubbles can be manufactured.Also, the adhesive resin is in the form of a powder. Therefore, the excess of the adhesive resin powder coated on the glass plate can be easily collected and reused.
