Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines hinterschäumten Verbundformteils mit den Merkmalen des Anspruchs 1.The invention relates to a method for producing a foam-backed composite molding with the features of claim 1.
Es ist bekannt, hinterschäumte Verbundformteile herzustellen, indem eine zu hinterschäumende Außenhaut, beispielsweise eine Leder- oder Textilhaut, in einen Formraum eines Formwerkzeuges eingelegt wird, das Formwerkzeug geschlossen wird und anschließend eine fließfähige, schäumbare Kunststoffmasse auf einer von der späteren Sichtseite abgewandten Seite der Außenhaut in den Formraum eingespritzt und aufgeschäumt wird. Hierbei wird das Problem aufgeworfen, dass an Nahtstellen oder etwaigen Beschädigungen der Außenhaut Schaumdurchbrüche auftreten. Um dies zu vermeiden, ist es bekannt, Nähte oder Defektstellen mit Klebefolienstreifen abzudecken oder Folienmeterware auf den gesamten Bereich aufzulegen. Dieser Verfahrensschritt ist jedoch, da er manuell erfolgt, sehr aufwendig und kostenintensiv. Ferner ist die erzielte Abdichtung, insbesondere bei komplexen Gestaltungen, oft nicht ausreichend.It is known to produce foam-backed composite moldings by inserting an outer skin to be foam-backed, for example a leather or textile skin, into a mold space of a molding tool, closing the molding tool and then a flowable, foamable plastic compound on a side of the outer skin facing away from the later visible side injected into the mold cavity and foamed. In this case, the problem is raised that occur at seams or any damage to the outer skin foam breakthroughs. In order to avoid this, it is known to cover seams or defect areas with adhesive film strips or to lay up foil stock on the entire area. However, this process step, since it is done manually, very expensive and expensive. Furthermore, the achieved sealing, especially in complex designs, often not sufficient.
Aus
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung eines hinterschäumten Verbundformteils bereitzustellen, bei dem Schaumdurchbrüche an Nahtstellen einer Außenhaut vermieden werden.The invention has for its object to provide a method for producing a foam-backed composite molding, are avoided in the foam breakthroughs at seams of an outer skin.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 gelöst. Erfindungsgemäß ist vorgesehen, dass vor oder nach dem Einlegen der Außenhaut, die eine Nahtstelle besitzt, in das Formwerkzeug eine Sperrschicht auf die von der Sichtseite abgewandte Seite der Außenhaut einschließlich der Nahtstelle durch Aufsprühen aufgetragen wird. Durch Aufsprühen kann eine sehr gleichmäßige und feindisperse Verteilung des Sperrschichtmaterials auf der Außenhaut einschließlich der Nahtstelle erzielt werden. Ferner wird eine sehr gute Haftung zwischen Außenhaut und Sperrschicht erreicht. Besonders vorteilhaft ist auch, dass sich das Aufsprühen einfach automatisieren lässt.This object is achieved by a method having the features of claim 1. According to the invention it is provided that before or after the insertion of the outer skin, which has a seam, in the mold a barrier layer is applied to the side facing away from the visible side of the outer skin including the seam by spraying. By spraying a very uniform and finely dispersed distribution of the barrier material on the outer skin including the seam can be achieved. Furthermore, a very good adhesion between the outer skin and barrier layer is achieved. It is also particularly advantageous that the spraying can be easily automated.
Das Verfahren ist besonders geeignet für Außenhäute aus Leder, Kunstleder oder Textilien.The method is particularly suitable for outer skins made of leather, synthetic leather or textiles.
Als Sperrschicht haben sich besonders Klebeschichten aus Polyurethan oder einem Dispersionskleber erwiesen.Adhesive layers of polyurethane or a dispersion adhesive have proven to be a barrier layer.
Nach einer besonders bevorzugten Ausgestaltung der Erfindung ist das hinterschäumte Verbundformteil eine Innenverkleidung für ein Kraftfahrzeug.According to a particularly preferred embodiment of the invention, the foam-backed composite molded part is an interior trim for a motor vehicle.
Die Erfindung wird nachfolgend anhand der zugehörigen Zeichnung näher erläutert.The invention will be explained in more detail with reference to the accompanying drawings.
