Abstract: 1,269,258. Laminates. BADISCHE ANILIN- & SODA-FABRIK A.G. 26 Aug., 1969 [27 Aug., 1968], No. 42446/69. Heading B5N. A method for the production of a flat structural sandwich comprises continuously preparing sheeting 4 by means of a screw extruder 2 at a material temperature of from 120 to 220 C. from a polyethylene having a density of from 0.918 to 0.930 g./cm. 3 and melt index (ASTM D 1238-65 T) of from 0.2 to 5, continuously covering the sheeting on each surface by a pair of rollers 7 with a film 6 having a thickness of 0À01 to 0.2 mm. of a terpolymer containing 60 to 90% by weight of ethylene units, 0.5 to 20% by weight of units of an ethylenically unsaturated carboxylic acid e.g. acrylic acid and 0À5 to 20% by weight of units of an ester of an ethylenically unsaturated carboxylic acid e.g. t-butyl acrylate, the resultant laminate being continuously covered on each surface by a pair of rollers 9 with metal sheeting 8 e.g. aluminium, copper, brass or steel, having a thickness of from 0.05 to 2.5 mm. and at a temperature of from 100 to 250 C., the whole being bonded into a sandwich construction by the rollers 9 under a pressure of from 5 to 50 kp/cm., the product being cooled in cooling zone 10 to a temperature of less than 60 C. and cut into panels by cutting means 11.

Abstract: A process for the production of sandwich constructions consisting of (a) an inner ply of polyethylene; (b) adhesion-promoting interlayers applied to both sides of the inner ply and (c) outer plies of metal applied to the two interlayers. It is a characteristic feature of the invention that sheeting is prepared continuously from a special polyethylene by means of a screw extruder at a specific temperature of the material, this sheeting is covered on both sides with a film of a special polymer by means of a pair of rollers, the resultant laminate is then covered continuously by means of a pair of rollers at a specific temperature of the material with metal sheeting having a specific temperature and the whole is combined to form a sandwich panel under a specific roller pressure. The process gives sandwich constructions having particularly good chemical and physical properties in a simple way.
