摘要:
The invention concerns a method for the production of a flat composite (5) from plastic parts by means of a thermal adhesion of two plastic parts (1,1′), heated on one side of their surfaces (1a,1a′), consisting of plastics A and B, wherein the surfaces (1a,1a′) are heated on the adhesion side to surface temperatures of 10 to 100° K. above the Vicat softening points VET (according to DIN ISO 306) of the pertinent plastics A and B, provided that the plastic parts (1,1′) retain their original shape during the preheating phase, and are pressed between a pair of rolls (2,3), at an advance rate between 5 and 200 mm/sec and with a pressing force between 10 and 500 N acting on the roll (3); preferably, the plastics (1,1′) exhibit engraving or embossing (6,6′), with which composite (5) can be produced with a three-dimensional inclusion (7) of a defined shape; furthermore, a flat or elongated object (8) is embedded between the plastic parts (1,1′) to be adhered during the adhesion of the composite (5).

摘要:
The invention relates to a method for the production of flat laminates (5) from polymethacrylate plastic, by thermal adhesion of at least two parts (1) of polymethacrylate plastic heated at their surface, with the characterizing features that the parts (1) of polymethacrylate plastic, which have been preheated to surface temperatures of 130.degree. to 200.degree. C. on the adhesion side (1a), and which maintain their original shape during the preheating phase, are pressed together between a pair of rollers (2, 3), of which at least one roller (2), by means of which the pressure force (4) is exerted, is mounted in movable manner, at a feed velocity being between 5 and 200 mm/s and a pressure force acting on the roller (3) between 10 and 500 N. Preferably, during the adhesion of the laminates (5), flat or oblong objects (8) with thicknesses which are allowed to amount to a maximum of 50% of the thickness of the parts (1) of polymethacrylate plastic, are embedded between the parts (1) of polymethacrylate plastic which are to be adhered together.

The invention relates to a moulding composition and to the mouldings which can be produced therefrom. Due to their good resistance in the hot water cycle test and in the hot-water/isopropanol test, the plastics mouldings have particularly good suitability for the production of sanitary components.
