Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Herstellung eines Kompositbauteils, umfassend die Schritte: • i) Aufträgen einer wässrigen Zusammensetzung, die eine Polychloropren-Dispersion und/oder eine Polyurethan-Dispersion enthält, auf mindestens ein Vlies; • ii) Koagulieren der wässrigen Zusammensetzung auf dem Vlies durch in-Kontakt-bringen mit einem Koagulationsmittel und/oder Erwärmen auf 80 bis 220 °C, um ein Halbzeug zu formen; und iii) gegebenenfalls Anbringen eines Dekors, welches einen Klebefilm aufweist; und • iv) danach Verformen des Halbzeugs aus Schritt ii) oder iii) durch Pressen und/oder Erwärmen auf 30 bis 220 C°, um das Kompositbauteil zu erhalten, dadurch gekennzeichnet, dass die wässrige Zusammensetzung mindestens einen Verdicker enthält. Ferner betrifft die Erfindung die Verwendung des Kompositbauteils der vorliegenden Erfindung als Bestandteil einer Innenraumverkleidung, einer Sonnenblende, eines Trägerteils, einer 2- oder 3-dimensionalen Schallschutzplatte, eines 3-dimensionalen Druckbauteils, eines Polsterwerkstoffes, eines Anfahrtschutzes, einer Sitzschale und einer Stoßisolierung.
(EN)
The invention relates to a method for producing a composite component, comprising the steps: i) applying an aqueous composition, which contains a polychloroprene dispersion and/or a polyurethane dispersion, to at least one nonwoven; ii) coagulating the aqueous composition on the nonwoven by bringing the aqueous composition into contact with a coagulant and/or heating to 80 to 220 °C, in order to form a semifinished product; and iii) optionally attaching a decoration, which comprises an adhesive film; and iv) thereafter, shaping the semifinished product from step ii) or iii) by pressing and/or heating to 30 to 220 °C, in order to obtain the composite component, characterized in that the aqueous composition contains at least one thickener. The invention further relates to the use of the composite component of the invention as part of an interior trim, of a sun visor, of a support part, of a 2- or 3-dimensional sound-proofing panel, of a 3D-printed component, of a padding material, of a collision protection means, of a seat shell and of an impact isolation means.
(FR)
L’invention concerne un procédé de fabrication d’un composant composite, comprenant les étapes suivantes : • i) appliquer une composition aqueuse qui contient une dispersion de polychloroprène et/ou une dispersion de polyuréthane sur au moins un non tissé ; • ii) coaguler la composition aqueuse sur le non-tissé par mise en contact avec un coagulant et/ou par chauffage à une température de 80 à 220 °C pour former un produit semi-fini ; et • iii) le cas échéant, fixer un décor comportant un film adhésif ; et • iv) déformer ensuite le produit semi-fini de l’étape ii) ou iii) par pressage et/ou chauffage à une température de 30 à 220 °C afin d’obtenir le composant composite. L’invention est caractérisée en ce que la composition aqueuse contient au moins un épaississant. En outre, l’invention concerne l’utilisation du composant composite de la présente invention comme constituant d’un revêtement d’espace intérieur, d’un pare-soleil, d’une partie de support, d’une plaque d’insonorisation bidimensionnelle ou tridimensionnelle, d’un composant d’impression tridimensionnelle, d’un matériau de rembourrage, d’une protection contre les collisions, d’une coque de siège et d’une isolation contre les chocs.
