FIRE-RETARDANT LAMINATED GLASS AND FIRE-RETARDANT FACILITY WITH FIRE-RETARDANT LAMINATED GLASS

摘要

PROBLEM TO BE SOLVED: To provide fire-retardant laminated glass in which a fire retardant property can be improved by preventing the glass from being broken by increase in pressure of a gas which is generated by thermal decomposition of an adhesive or the like when a fire occurs.SOLUTION: In fire-retardant laminated glass, confronted glass plates 10 are pasted together by an adhesive while interposing a resin film 11 therebetween. At least one of the confronted glass plates 10 is comprised of heat-resistive plate glass and at least one of adhesives for forming adhesive layers 12, 12 is comprised of a thermoplastic adhesive with a thermoplastic resin as a main component. Further, the resin film 11 is comprised of a resin material of which the oxygen index at normal temperature exceeds 21.
