Abstract

774,049. Laminated materials. INTERNATIONELLA SIPOREX AKTIEBOLAGET. May 31, 1955 [June 4, 1954], No. 15517/55. Class 140. A composite slab or door panel is made by uniting outer layers to a core of porous mineral material by means of a thermosetting synthetic resin by pressure at a temperature of 90- 160‹ C. to cure the resin, and is cooled under pressure until the core temperature differs from the atmosphere by at most 50‹ C. The core may be a light ceramic slab, a slab produced from pumice stone or slag and a binder, foam concrete, or expanded, steam-cured, lightweight concrete. The outer layers may be of wood veneer, plywood, wood fibre board, asbestos cement, laminated synthetic resinous material, or sheet metal. Phenol-, urea-, and melamine-aldehyde resins may be used as adhesive. In examples: (1) in the production of a door panel, a light-weight concrete core is cemented together with a surrounding frame of wood, is ground smooth, is covered on both sides with phenol-aldehyde resin-impregnated paper, wood veneer, a second layer of resin-impregnated paper and a birch veneer, hotpressed, and then cooled under pressure; (2) a foam concrete slab is ground flat, coated on both sides with an aqueous dispersion of a resorcinol-aldehyde resin containing formalin as hardener and nutshell flour as a filler, and, after applying asbestos cement plates on the adhesive-coated surfaces, the assembly is hotpressed and allowed to cool under pressure. The foam concrete slab may be provided with a centrally located transport reinforcement of two iron rods passing longitudinally through the slab, to stiffen the slab until the outer layers have been applied.
