发明名称 PLASTIC-PAPER COMPOSITE IN FOIL FORM AND ITS USE FOR PRODUCING WEATHERPROOF LAMINATED SHEETS WITH SURFACE PROTECTION
摘要 The invention concerns a plastics-paper composite which substantially consists of a paper layer (5), a polypropylene layer (6) and a polyester layer ( 7), the polyester layer forming one of the two surface layers of the plastics-paper composite. This plastics-paper composite is used to produce weatherproof laminated sheets (13) with surface protection, an acrylate layer (8, 11) being applied to the polyester layer of the plastics-paper composite. This composite i s stacked on one or both sides with a plurality of papers impregnated with synthet ic resin to form a stack, the acrylate layer(s) lying against the outermost paper layer(s) (9). This stack is then pressed at high pressure and high temperature. For use, the surface protection is removed from the acrylate layer as from the polyester layer.
