Abstract
1281276 Laminates MITSUI PETROCHEMICAL INDUSTRIES Ltd 5 May 1970 [6 May 1969] 21592/70 Heading B5N A method of manufacturing a compound sheet of thermoplastic synthetic resin includes the steps of forwarding and corrugating a first continuous sheet f 1 of thermoplastic synthetic resin to form a core sheet, forwarding a surface sheet f 2 , f 3 of thermoplastic synthetic resin to a position adjacent each face of the core sheet, providing a single thin layer B of a further thermoplastic synthetic resin between each face of the core sheet and the adjacent surface sheet respectively, the further thermoplastic synthetic resin having a softening point at least 10‹ C. lower than the softening point of that one of the materials forming the core and surface sheets which has the lowest softening point, and bonding the surface sheets to the core sheet with heat and pressure such that the further thermoplastic synthetic resin only is softened. The thin layers of the further thermoplastic synthetic resin may be provided on each surface of the core sheet; alternatively, the said thin layers may be provided on the faces of the surface sheets which are to be bonded to the core sheet. The core and surface sheets which may be foamed and may be made by extrusion moulding, casting or calendering may be made from polyvinyl chloride, polyvinylidene chloride, polystyrene, low density polyethylene, high density polyethylene, a copolymer of ethylene and propylene, polypropylene, polybutylene or poly-4-methyl-pentene-1. The further thermoplastic synthetic resin used in the thin thermoplastic layers may be a copolymer of ethylene with a vinyl ester of a saturated monocarboxylic acid, a copolymer of ethylene with an unsaturated carboxylic acid, a copolymer of ethylene with an ester of an unsaturated carboxylic acid, a terpolymer of ethylene with a vinyl ester of a saturated monocarboxylic acid and an unsaturated carboxylic acid or a partial metal salt of a copolymer of ethylene with an unsaturated carboxylic acid, many suitable co-monomers being specified.
