Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Formkörpers aus einer Kunststoffträgerschicht und den daraus resultierenden Formkörper, dessen Oberfläche zumindest teilweise mit einer genarbten Folie überzogen ist.The The present invention relates to a process for producing a molding from a plastic carrier layer and the resulting molded body whose surface is at least partially covered with a grained foil.
Genarbte
Folien werden heutzutage oftmals zur Kaschierung von Kraftfahrzeuginnenausstattungsteilen
eingesetzt. Es gibt deshalb mehrere gewerbliche Schutzrechte, die
sich mit der Herstellung von genarbten Folien bzw. Bauteilen, die
mit einer genarbten Folie kaschiert sind, beschäftigen. Beispielsweise lehrt
das deutsche Gebrauchsmuster
Bei den mit genarbten Folien kaschierten Bauteilen wird häufig eine Trägerschicht, beispielsweise ein Naturfaserpressteil oder eine thermoplastische Kunststoffträgerschicht, welcher durch Pressen oder Spritzgießen hergestellt wurde, mit einer genarbten Folie überzogen. Bei dem Kaschiervorgang, der mit einer hohen Dehnung der genarbten Folie einhergeht, werden oftmals, insbesondere im Randbereich des Trägers, die auf der Folie befindlichen Narben verstreckt, was in einigen Bereichen zu massiven Anmutungsverlusten führt.at the laminated with grained films components is often a Support layer, for example, a natural fiber press or a thermoplastic Plastic carrier layer, which was produced by pressing or injection molding, with a grained foil coated. In the laminating process, with a high elongation of the grained Foil is associated, are often, especially in the edge region of the support the scars on the film stretched, resulting in some Areas leads to massive loss of appearance.
Es war deshalb die Aufgabe der vorliegenden Erfindung, ein Verfahren zur Herstellung eines Formkörpers, der aus einer Kunststoffträgerschicht besteht, deren Oberfläche zumindest teilweise mit einer genarbten Folie überzogen ist, zur Verfügung zu stellen, bei dem der o. g. Anmutungsverlust nicht auftritt.It was therefore the object of the present invention, a method for producing a shaped body, which consists of a plastic carrier layer, their surface at least partially coated with a grained film, to provide in which the o. g. Appearance loss does not occur.
Gelöst wird diese Aufgabe mit einem Verfahren zur Herstellung eines Formköpers aus einer Kunststoffträgerschicht deren Oberfläche zumindest teilweise mit einer genarbten Folie überzogen ist, bei dem eine ungenarbte Folie in ein Werkzeug eingelegt wird, dessen Oberfläche das Negativ von Narben aufweist und dass der Kunststoff, aus dem die Kunststoffträgerschicht besteht rückseitig der Folie injiziert und die Folie von dem Kunststoff in das Negativ der Narben des Werkzeuges gedrückt wird.Is solved this task with a method for producing a molded body a plastic carrier layer their surface at least partially coated with a grained film, in which a unhardened film is placed in a tool whose surface is the Has negative of scars and that the plastic from which the Plastic carrier layer exists on the back the film is injected and the film from the plastic into the negative the scars of the tool pressed becomes.
Es war für den Fachmann überaus erstaunlich und nicht zu erwarten, dass es mit dem erfindungsgemäßen Verfahren gelingt, einen kaschierten Formkörper zur Verfügung zu stellen, der eine sehr hohe Anmutung aufweist. Das erfindungsgemäße Verfahren ist einfach und kostengünstig und mit einer hohen Reproduzierbarkeit durchzuführen. Es ist möglich, mehrere Bereiche mit unterschiedlichen Narben sowie kaschierte und unkaschierte Bereiche auf dem Formkörper zu realisieren.It was for the expert very much Amazing and not to be expected with the method of the invention succeeds, a laminated molding to disposal to provide, which has a very high appearance. The inventive method is easy and inexpensive and to perform with a high reproducibility. It is possible several Areas with different scars as well as laminated and unlaminated Areas on the molding to realize.
Erfindungsgemäß erfolgt die Narbung der Folie und die Herstellung des Formkörpers in einem Werkzeug. Die Folie, insbesondere eine thermoverformbare Kunststofffolie, die vorzugsweise aus einem Polyolefin oder aus einem Polyolefine enthaltenden Kunststoff besteht, wird im ungenarbten Zustand in ein Werkzeug eingelegt, in das das Negativ der herzustellenden Narben eingearbeitet, beispielsweise eingeätzt, ist. Des weiteren weist das Werkzeug einen Raum auf, in den der Kunststoff, aus dem die Kunststoffträgerschicht des Formkörpers besteht, eingespritzt werden kann. Das Einspritzen des Kunststoffs erfolgt gemäß dem sogenannten Spritzgussverfahren, insbesondere dem Hinterspritzverfahren, nachdem die glatte Kunststoff-Folie in das Werkzeug eingelegt worden ist. Durch den Druck, mit dem der Kunststoff der Kunststoffträgerschicht in das Werkzeug eingespritzt wird, wird die Folie gegen die Negative in der Oberfläche des Werkzeuges gedrückt und formt diese aus, so dass die Folie ihre genarbte Struktur annimmt. Gleichzeitig oder danach verbindet sich die Folie mit dem Kunststoff der Kunststoffträgerschicht. Der Kunststoff der Kunststoffträgerschicht ist ein dem Fachmann bekannter thermoplastischer Werkstoff. Dadurch, dass das gesamte Verfahren in einem Werkzeug stattfindet, lassen sich sehr kostengünstige Bauteile erzeugen. Eine Streckung der Narben bei der Verbindung zwischen der Trägerschicht und der Kaschierfolie tritt nicht mehr auf.According to the invention the graining of the film and the production of the molding in a tool. The film, in particular a thermoformable plastic film, preferably made of a polyolefin or of a polyolefin containing plastic, is in the unhardened state in a tool inserted into which the negative of the scars to be made incorporated, for example etched is. Furthermore, points the tool has a space in which the plastic from which the plastic backing layer of the molding exists, can be injected. The injection of the plastic takes place according to the so-called Injection molding process, in particular the injection molding process, after the smooth plastic film has been inserted into the tool. By the pressure with which the plastic of the plastic carrier layer injected into the tool, the film is against the negatives in the surface of the tool and shapes them so that the film takes on its grained texture. At the same time or after the film connects to the plastic the plastic carrier layer. The plastic of the plastic carrier layer is a thermoplastic material known to those skilled in the art. Thereby, let the whole process take place in a tool very cost effective Create components. An extension of the scars at the connection between the carrier layer and the laminating film does not occur anymore.
Vorzugsweise handelt es sich bei dem Kunststoff, auf dem das Trägermaterial hergestellt wird, um einen thermoplastischen Kunststoff.Preferably it is the plastic on which the carrier material is made to a thermoplastic.
Die Folie, insbesondere eine thermoverformbare Kunststofffolie, besteht vorzugsweise aus einem Polyolefin oder aus einem Polyolefine enthaltenden Kunststoff. Die Folie kann ein Verbund aus mehreren Schichten sein. Beispielsweise kann die Folie auf ihrer Rückseite eine Schaumschicht aufweisen.The Film, in particular a thermoformable plastic film exists preferably from a polyolefin or from a polyolefin-containing plastic. The film can be a composite of several layers. For example Can the film on its back have a foam layer.
In einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens wird die Folie vor und/oder während des Injizierens mit Vakuum an die Oberfläche des Werkzeuges gezogen. Diese Ausführungsform des erfindungsgemäßen Verfahrens hat den Vorteil, dass das Vakuum die Ausformung der Narben in der Folie unterstützt.In a preferred embodiment the method according to the invention the film is before and / or during of injection with vacuum drawn to the surface of the tool. This embodiment the method according to the invention has the advantage that the vacuum the shaping of the scars in the Slide supported.
Das erfindungsgemäße Verfahren eignet sich insbesondere zur Herstellung von Formkörpern, wie sie beispielsweise bei Bauteilen der Innenausstattung von Kraftfahrzeugen eingesetzt werden. Ein weiterer Gegenstand der vorliegenden Erfindung ist deshalb ein Formkörper erhältlich mit dem erfindungsgemäßen Verfahren.The inventive method is particularly suitable for the production of moldings, such as For example, in components of the interior of motor vehicles be used. Another object of the present invention is therefore a shaped body available with the method according to the invention.
Der erfindungsgemäße Formkörper weist eine sehr hohe Anmutung auf. Insbesondere Bereiche, in denen eine ungewollte schwache Narbung vorhanden ist, treten nicht auf. Der erfindungsgemäße Formkörper kann mehrere unterschiedliche Narbungen sowie kaschierte und unkaschierte Bereiche aufweisen. Der erfindungsgemäße Formkörper ist klebstofffrei, da sich die Kunststoffträgerschicht und die Kaschierschicht, die als Dekorschicht fungiert und die insbesondere eine Folie ist, während der Herstellung verbinden.Of the Shaped body according to the invention has a very high appearance. In particular, areas where an unwanted weak graining is present, do not occur. The molding according to the invention can several different graining as well as laminated and unlaminated Have areas. The molding according to the invention is free of adhesive, since the plastic carrier layer and the laminating layer, which acts as a decorative layer and the particular a slide is while connect the production.
