Abstract: A fire-protection and safety composite glass panel includes a fireproof glass plate and a film of fluorocarbon resin of a chain molecular structure type. The film is bonded onto one of opposite side surfaces of the fireproof glass plate by the thermo-compression bonding. The fluorocarbon resin is a copolymer of at least three kinds of monomers. It may be arranged that another film of the fluorocarbon resin is further bonded onto the other side surface of the fireproof glass plate by the thermo-compression bonding. Another glass panel may be arranged that a plurality of fireproof glass plates are attached with a film of the foregoing fluorocarbon resin interposed between adjacent glass plates through the thermo-compression bonding. Those glass panels can be used as glass plates in fire-protective windows and doors.

Abstract: In a fire-protection and safety glass panel having a transparent appearance and dual functions as a fire protection glass for shutting out flame and smoke for a long period of time upon occurrence of fire and as a safety glass which is neither shattered into pieces and nor forms any through hole if it is broken in an ordinary life, a PET (polyethylene terephthalate) film (12) is arranged between a first glass plate (10) and a second glass plate (11). The first and the second glass plates (10 and 11) and the PET film (12) are adhered through transparent acrylic adhesive agent layers (13 and 14), respectively. An intermediate resin layer comprises the PET film (12) and the adhesive agent layers (13 and 14) and has a thickness between 75 and 200 .mu.m.

Abstract: A fire protective glass panel for use in a fire protective window, door, and partition wall, which comprises at least one sheet of fireproof glass plate and a fluorocarbone resin film of a chain molecular structure type bonded to a side surface of the glass plate and which has non-shattering property as well as fire protection property wherein the fireproof glass plate is a heat-resistant and light transparent crystallized glass plate or, alternatively, the fireproof glass plate is a wire glass plate and the fluorocarbone resin film has a thickness of 0.02-1 mm and is made of one of FEP, PFA, PCTFE, ETFE, and PVDF.
