It is also widely used for architectural window glass. Such laminated glass is manufactured by pre-pressing a laminate of a pair of transparent plates stacked on top of each other with an interlayer interposed therebetween, followed by main bonding. Methods for pre-pressing the laminate include a method of passing the laminate between nipper rolls and a method of vacuum reduction. The method using vacuum depressurization is generally referred to as vacuum bonding, and is classified into a gasket method in which the laminate is surrounded by a rubber tube, and a rubber bag method in which the entire laminate is housed in a rubber bag.

Next, the inside of the rubber bag 30 is depressurized and degassed to a predetermined degree of vacuum, and while this state is maintained, the laminate 20 inside the rubber bag 30 is heated. The air present between the transparent plate 21 and the intermediate film 22 is removed by reducing the vacuum inside the rubber bag 30. Further, due to the pressure difference between the inside and outside of the bag 30 due to this vacuum reduction, the laminate 20 receives a pressure bonding load from the outside, and is heated in this state, so that the transparent plates 21, 21 are attached to the intermediate film 2.

When the unevenness formed on the surface is rough or when the inside of the rubber bag 30 is reduced to a high vacuum, the air existing between the transparent plate 21 and the intermediate film 22 is sufficiently removed. However, when the roughness of the unevenness formed on the surface of the intermediate film 22 is small,
When the degree of vacuum inside the rubber bag 30 is relatively low, the transparent plate 2
Since the air existing between 1 and the interlayer film 22 is difficult to escape,
The laminate 20 is removed with air remaining in the center of the laminate 20.
There is a risk that a so-called peripheral seal may occur, in which the peripheral portion of the material is crimped first. If this peripheral seal occurs, the laminate 20 after preliminary pressure bonding is placed in an autoclave and pressure bonded under high temperature and high pressure.This may cause quality deterioration such as bubbles remaining in the product after main bonding or bubbles appearing during use of the product. .

For example, when the heating temperature T of the laminate 20 is around 100°C, the heat deformation temperature T of the shape memory alloy is preferably 50 to 80°C. The top plate part 12 and the bottom plate part 11 are formed to have such rigidity that they will not be deformed even when the holder 10 receives a vacuum reduction for pre-pressing the laminate 20.

段階では積層体２０は充分に脱気された状態となる。As shown in FIG. 3, the laminate 20 is placed in the holder 10 so that spaces are formed between its upper surface and the top plate 12, and between its lower surface and the bottom plate 11. Insert into. Next, this holder 10 is inserted into the bag 30, and the inside of the bag 30 is heated while being decompressed and degassed to a predetermined degree of vacuum. As a result, the bag 30 contracts due to the pressure difference between the inside and outside, and the contractile force is applied to the periphery of the holder 10. Here, the holder 10 has a predetermined rigidity, and the bag body 30
Since the holder 10 is not deformed by the pressure on the holder 10, the contractile force of the bag 30 does not act on the outer surface of the laminate 20. Therefore, even if the fine irregularities formed on the surface of the interlayer film 22 are small or the ability of the deaerator to reduce the pressure inside the bag body 30 is low, there is a gap between the transparent plate 21 and the interlayer film 22. Existing air can be efficiently and quickly discharged, and when the inside of the bag 30 reaches a predetermined degree of vacuum, the stacked body 20 is in a sufficiently deaerated state.

Thereby, the holder 10 is attached to the bag body 3.
Since it is no longer possible to maintain the contraction force from 0, the predetermined pressure bonding load due to the pressure difference between the inside and outside of the bag 30 is
The laminate 20 is sufficiently evacuated by this pressure bonding load and the heating.

。[Operation] When the laminate is housed in the holder and the bag is vacuum depressurized at a temperature below the deformation temperature T of the switching means provided in the holder, the periphery of the laminate is Since the pressure inside the bag can be reduced without any pressure applied by the bag, the gas existing between the interlayer film and the transparent plate of the laminate can be efficiently discharged from the periphery of the laminate to the outside. Can be done. When the holder is heated to a temperature higher than the thermal deformation temperature T of the switching means as the laminate is heated, the switching means will be thermally deformed and will no longer be able to resist the pressure bonding load from the bag. The laminate receives a predetermined pressure bonding load from the bag and is heated in this state, thereby preliminarily bonding the laminate to a predetermined strength.

It is possible to quickly and sufficiently exhaust gases that may be present. Moreover, when the laminate is hot-pressed, the switching means is thermally deformed, and a sufficient crimping load is applied to the laminate, so that the laminate can be reliably crimped. Further, since the switching means is naturally deformed using heating for crimping, no special operation is required.
