Title (EN) METHOD FOR PRODUCING A POLYMER PROFILE BY MEANS OF CHEMICAL CROSS-LINKING

Abstract:
(EN) The invention relates to a method for producing a polymer profile (1) by means of chemical cross-linking, wherein initially a plastic profile (3) is made from a synthetic material (K) with added additives (4), then the plastic profile (3) is heated by a heat source (5) emitting radiation and the additives (4) added to the synthetic material (K) undergo thermal decomposition to produce radicals, the radicals performing a chemical cross-linking of the synthetic material (K). According to the invention, pigments (6) adapted to the radiation of the heat source (5) are added to the synthetic material (K) in addition to the additives (4) and the plastic profile (3) having an outer layer (7), preferably a plastic outer layer, which has a low weight concentration of pigments (6) is provided as a synthetic material (K).
(FR) L'invention concerne un procédé de fabrication d'un profilé polymère (1) par réticulation chimique, un profilé en plastique (3) étant d'abord fabriqué à partir d'une matière plastique (K) contenant des additifs ajoutés, le profilé en matière plastique (3) étant ensuite chauffé au moyen d'une source de chaleur (5) émettant un rayonnement et les additifs (4) ajoutés à la matière plastique (K) se décomposant ainsi thermiquement en radicaux, ces radicaux provoquant une réticulation chimique de la matière plastique (K). Selon l'invention, des pigments (6) adaptés au rayonnement de la source de chaleur (5) sont ajoutés à la matière plastique (K) en plus des additifs (4) et le profilé en plastique (3) est pourvu d’une couche extérieure (7), de préférence d’une couche extérieure en plastique qui présente une concentration en poids de pigments (6) plus faible que celle de la matière plastique (K).
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung eines polymeren Profils (1) mittels chemischer Vernetzung, wobei zunächst ein Kunststoffprofil (3) aus Kunststoffmaterial (K) mit zugesetzten Additiven (4) gefertigt wird, wobei danach das Kunststoffprofil (3) mittels einer Strahlung emittierenden Wärmequelle (5) erwärmt wird und hierdurch die dem Kunststoffmaterial (K) zugesetzten Additive (4) thermisch zu Radikalen zerfallen, und wobei diese Radikale eine chemische Vernetzung des Kunststoffmaterials (K) bewirken. Erfindungsgemäß werden dem Kunststoffmaterial (K) neben den Additiven (4) an die Strahlung der Wärmequelle (5) angepasste Pigmente (6) zugesetzt und das Kunststoffprofil (3) mit einer Außenschicht (7), vorzugsweise Kunststoff-Außenschicht, versehen, die eine niedrigere Gewichtskonzentration an Pigmenten (6) aufweist als das Kunststoffmaterial (K).
