PREPARATION OF THERMAL INSULATION FOLDING BOARD

摘要

PURPOSE: To avoid a bulge phenomenon generated by gas generated from the remaining solvent of an adhesive and remaining air being stored in the interface of adhesion with a metal sheet by applying the adhesive into an island-like shape or a belt-like shape on the face of the side adhered on the metal sheet as a closed-cell foamed sheet. CONSTITUTION: When a thermal insulation folding board 8 as an adhesive body 7 is prepd. by bonding together a metal sheet 3 and a closed-cell foamed sheet 1 by means of press rolls 5, the closed-cell foamed sheet 1 on one face of which an adhesive 2 is applied into a belt-like shape or an island-like shape is used. Air involved when bonded together by means of the press rolls is escaped to the outside of the bonded body through parts on which the adhesive 2 is not applied and even when the adhesive 2 remains, gas generated by evaporation of the solvent can be escaped to the outside of the bonded body 7 through parts on which the adhesive is not applied not to cause bulge phenomenon.
