HEATING LOSSY PRESSURE-SENSITIVE ADHESIVE SHEET, EXPLOSION-PROOF STRUCTURE OF CATHODE RAY TUBE AND EXPLOSION-PROOF TAPE OF CATHODE RAY TUBE

摘要

PURPOSE: A heating lossy pressure-sensitive adhesive sheet, an explosion-proof structure of a cathode ray tube, and an explosion-proof tape of a cathode ray tube are provided, which can melt an adhered without removing the pressure-sensitive adhesive layer, and has no damage on the quality of a withdrawn material resulted from a carbonation of a component of the pressure-sensitive adhesive layer. CONSTITUTION: The heating lossy pressure-sensitive adhesive sheet includes more than one heating lossy pressure-sensitive adhesive layer(22) below 5 wt% of which remains when it is thermally annealed under a temperature below 700 deg.C for a time below 30 minutes. And the pressure-sensitive adhesive layer is constituted with a polybutene or a poly lauryl methacrylate. The pressure-sensitive layer is arranged on one surface or on both surfaces of a heating lossy supporting base film(21), and is used for an adhesion of a product formed with a material which will be recycled by a melting.
