る。 Laminated glass plates, which are made by bonding multiple glass plates together with an adhesive transparent interlayer film, are excellent safety glasses and are used in automobiles and architecture, but they are very expensive. This is because the conventional interlayer film is a polyvinyl butyral film that has both the toughness that will not break even if the glass plate is broken and the adhesiveness that bonds the glass plates. To manufacture the glass, an interlayer film must be inserted between the glass plates, pre-pressed, and then heated in an autoclave for the final press-bonding, which complicates the manufacturing process and increases labor costs. This is because not only does the burden increase, but also the final crimping, especially using an autoclave, impedes continuous production, thereby increasing production costs.

A liquid defoaming agent made of phthalate or phosphoric ester is present on the adhesive surface of the glass plate, and when the plastic film is pressed onto the glass plate, the air bubbles generated between the adhesive layer and the glass plate are removed together with the liquid defoaming agent. The present invention relates to a method for manufacturing laminated glass, characterized in that the laminated glass is discharged from the glass.

It should satisfy various requirements such as being free from heat and being weather resistant. Examples of the film material used include polyester resin, polypropylene resin, polycarbonate resin, nylon resin, polyethylene resin, and acrylic acid ester resin, but polyester resin films are particularly excellent in all respects.
