Abstract

PURPOSE:To obtain laminated glass which is free from foaming and peeling of a plastic intermediate film after long term use by sandwiching said intermediate film between glass plates, press sticking the same, and packing a moisture impermeable sealant in the notch formed in the circumferential edge part. CONSTITUTION:A plastic intermediate film 1 of polyvinyl butyral or the like for lamination is cut to the size shorter than the entire circumferential edge of glass plates 2, 3 to be laminated and the cut film is placed on one glass plate 2 to make a region where the film 1 is not placed uniformly in the circumferential edge part. A release type soft spacer 4 is disposed in the marginal part at the circumferential edge of the plate 2 where the intermediate film is not placed. Another sheet of glass plate is placed on the film 1 and the spacer 4 of said glass plate and is press stuck preliminarily, whereafter both are press stuck under required temp. and pressure to form laminated glass. The spacer 4 is removed and a moisture impermeable sealant 6 is packed in the notched part 5 formed after said removal.

In the preliminary crimping step, the conventional method is used, for example, by placing a laminate of multiple glass plates and a plastic interlayer film in a rubber bag, and applying pressure within the rubber bag to 700 tones of Hg or less, for example, 200 tones of Hg. After depressurizing to ~650 mm Hg, 10
A method of pre-pressing by heating to 0°C or less, for example from room temperature to 90°C, and also fitting a deaeration gasket e to the peripheral edge of the laminate. In addition to the method of pre-pressing by heating, the laminate is placed in the inner vacuum chamber (for example, a vacuum bag) of a decompression device having double vacuum chambers, the outer vacuum chamber is first degassed, and then the inner "g4II" is degassed. It is also possible to use a double vacuum crimping method, in which the vacuum chamber on the outside is degassed, then the vacuum in the outer vacuum chamber is released, and crimping is carried out at atmospheric pressure.

Next, the releasable soft spacer placed around the periphery of the laminated glass is removed, and the laminated glass is sealed as a moisture-impermeable sealant, which is important to be impermeable to water and gases containing moisture. Also, it is suitable to use a material that has good adhesion to the glass plate and has low-temperature flexibility to follow the vibrations of the glass plate. For example, examples of the moisture-impermeable sealant include butyl rubber thread sealant, polyimbutylene sealant, polysulfide sealant, polyurethane sealant, silicone sealant, and the like. This sealing material is applied, for example, by using a special applicator 7, or by using a string-like sealing material jig to fill the peripheral edge of the glass plate. Then, it is cured if necessary. This moisture-impermeable sealing material does not necessarily need to be provided over the entire width of the peripheral edge of the glass plate where the plastic interlayer film for lamination is not placed.
