It is essential to the invention that a carrier film (18) is applied at least in sections to the wood layer (12), then at least one groove (20) is introduced into the decorative layer (10) which completely cuts through the wood layer (12), then the decorative layer (10 ) is back-injected with the substrate (24).
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Zierelements mit einer Dekorschicht und einem Substrat, wobei die Dekorschicht eine Holzschicht und eine Trägerschicht aufweist, auf welcher die Holzschicht aufgebracht ist.The invention relates to a method for producing a decorative element with a decorative layer and a substrate, wherein the decorative layer has a wood layer and a carrier layer on which the wood layer is applied.
Solche Zierelemente werden vielfältig im KFZ-Bereich eingesetzt, um den Innenraum eines Kraftfahrzeugs zu verkleiden. Durch die Verwendung besonderer Hölzer kann somit ein edler optischer Eindruck des Innenraums erzielt werden. Allerdings ist das Aussehen dieser Zierelement hauptsächlich durch die Maserung des Holzes gegeben. Die optischen Möglichkeiten, die natürlich gewachsene Hölzer bieten, werden bereits ausgenutzt. Solche Zierelemente bieten daher kein Alleinstellungsmerkmal. Wünschenswert wäre es, solche Holzzierelemente mit weiteren Effekten belegen zu können.Such trim elements are widely used in the automotive field to disguise the interior of a motor vehicle. By using special woods thus a noble visual impression of the interior can be achieved. However, the appearance of this decorative element is mainly given by the grain of the wood. The optical possibilities offered by naturally grown woods have already been exploited. Such decorative elements therefore offer no unique selling point. It would be desirable to be able to prove such Holzzierelemente with other effects.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine verbesserte oder zumindest andere Ausführungsform eines Zierelements bereitzustellen, welche sich insbesondere durch einen hochwertigeren optischen Eindruck auszeichnet.The present invention has for its object to provide an improved or at least other embodiment of a decorative element, which is characterized in particular by a higher quality optical impression.
Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Unteransprüche.This object is achieved by the subject of the independent claim. Advantageous developments are the subject of the dependent subclaims.
Die Erfindung beruht auf dem allgemeinen Gedanken, bei einem Zierelement mit einer Dekorschicht, die aus einer Holzschicht und einer Trägerschicht besteht, die Dekorschicht teilweise zu durchbrechen, so dass die Trägerschicht sichtbar wird. Dadurch kann an diesen Stellen ein optischer Kontrast erzeugt werden. Durch einen künstlerischen Verlauf der Durchbrüche kann somit ein hochwertig anmutender optischer Effekt erzielt werden. Zweckmäßig ist es, dass eine Trägerfolie zumindest Abschnittsweise auf die Holzschicht aufgebracht wird, daraufhin mindestens eine Nut in der Dekorschicht eingebracht wird, die die Holzschicht vollständig durchschneidet, und daraufhin die Deckschicht mit einem Substrat hinterspritzt wird. Dadurch dass die Dekorschicht vollständig von der Nut durchschnitten wird, wird die hinter der Dekorschicht liegende Trägerfolie sichtbar und kann somit den gewünschten optischen Effekt erzielen. Das Substrat, welches hinter die Dekorschicht gespritzt wird, bildet dann das eigentliche Zierelement, welches mit der Dekorschicht ersehen wird.The invention is based on the general idea, in the case of an ornamental element with a decorative layer, which consists of a wood layer and a carrier layer, that the decorative layer partially breaks, so that the carrier layer becomes visible. As a result, an optical contrast can be generated at these points. Through an artistic course of the breakthroughs, a high-quality optical effect can thus be achieved. It is expedient that a carrier film is at least partially applied to the wood layer, then at least one groove is introduced into the decorative layer, which completely cuts through the wood layer, and then the cover layer is back-injected with a substrate. Because the decorative layer is completely cut through by the groove, the carrier foil lying behind the decorative layer becomes visible and can thus achieve the desired optical effect. The substrate, which is injected behind the decorative layer, then forms the actual decorative element, which is seen with the decorative layer.
Eine günstige Möglichkeit sieht vor, dass als Holzschicht Holzfurnier verwendet wird. Holzfurniere sind besonders dünn geschnittene Holzlagen. Dadurch kann die optischen Eigenschaften des Holzes genutzt werden. Gleichzeitig wird nur wenig Holz benötigt, so dass die Kosten gesenkt werden können.A favorable possibility provides that wood veneer is used as a wood layer. Wood veneers are particularly thinly cut wood layers. As a result, the optical properties of the wood can be used. At the same time, only a small amount of wood is needed so that the costs can be reduced.
Eine weitere günstige Möglichkeit sieht vor, dass ein Vlies zumindest abschnittsweise auf die Holzschicht aufgebracht wird. Somit bildet das Vlies zusammen mit der Trägerfolie die Trägerschicht, auf welche die Dekorschicht aufgebracht ist. Das Vlies lässt sich unter Umständen besser verformen als die Trägerfolie, so dass durch die Verwendung des Vlieses insgesamt die Dekorschicht besser umgeformt werden kann.Another favorable possibility provides that a nonwoven is at least partially applied to the wood layer. Thus, the nonwoven together with the carrier film forms the carrier layer, on which the decorative layer is applied. Under certain circumstances, the nonwoven can be better deformed than the carrier film, so that overall the decorative layer can be better formed by using the nonwoven.
Eine besonders günstige Möglichkeit sieht vor, dass als Trägerfolie eine kaltumformbare Folie verwendet wird. Somit kann die Dekorschicht in bekannten Umformverfahren umgeformt werden, um diese beispielsweise an eine Wölbung des Bauteils anzupassen.A particularly favorable possibility provides that a cold-formable film is used as the carrier film. Thus, the decorative layer can be formed in known forming processes, for example, to adapt to a curvature of the component.
Eine weitere besonders günstige Möglichkeit sieht vor, dass als Trägerfolie eine mit Holz verbindbare Folie verwendet wird. Dies ist insbesondere daher vorteilhaft, da somit keine Klebeschicht zwischen der Holzschicht und der Trägerfolie benötigt wird.Another particularly favorable possibility provides that a film that can be bonded to wood is used as the carrier film. This is particularly advantageous because thus no adhesive layer between the wood layer and the carrier film is needed.
Eine vorteilhafte Lösung sieht vor, dass als Trägerfolie eine Folie verwendet wird, die eine Verbindung mit dem Substrat eingehen kann. Dadurch wird die Verbindung zwischen dem Substrat und der Trägerfolien durch das Hinterspritzen des Substrats erzielt. Eine zusätzliche Klebeschicht ist daher nicht notwendig.An advantageous solution provides that the carrier film used is a film which can form a connection with the substrate. Thereby, the connection between the substrate and the carrier films is achieved by the injection molding of the substrate. An additional adhesive layer is therefore not necessary.
Eine weitere vorteilhafte Lösung sieht vor, dass als Trägerfolie eine Folie aus Polycarbonat, Acrylnitril-Butadien-Styrol und/oder aus Polyurethan verwendet wird. Diese Materialien lassen sich kaltumformen und sind mit üblichen Hinterspritzmaterialien für das Substrat verträglich.A further advantageous solution provides that a film of polycarbonate, acrylonitrile-butadiene-styrene and / or of polyurethane is used as a carrier film. These materials can be cold formed and are compatible with conventional backing materials for the substrate.
Eine besonders vorteilhafte Lösung sieht vor, dass die Trägerfolie durch Kleben, Kaschieren oder Verschmelzen mit der Holzschicht verbunden wird. So kann in einfacher Weise eine Verbindung der Holzschicht mit der Trägerfolie zu der Dekorschicht ermöglicht werden. A particularly advantageous solution provides that the carrier film is bonded by gluing, laminating or fusing with the wood layer. Thus, a connection of the wood layer with the carrier film to the decorative layer can be made possible in a simple manner.
Eine günstige Variante sieht vor, dass die mindestens eine Nut durch eine Schneidvorrichtung in die Dekorschicht eingebracht wird, beispielsweise durch einen Schneidplotter, einen Laser und/oder durch eine Fräse. Auf diese Weise lassen sich besonders einfach die Nuten erzielen, da insbesondere die Tiefe der Nuten genau eingestellt werden kann, so dass die Holzschicht vollständig durchschnitten wird und die Trägerfolie nicht vollständig durchschnitten wird.A favorable variant provides that the at least one groove is introduced by a cutting device in the decorative layer, for example by a cutting plotter, a laser and / or by a milling cutter. In this way it is particularly easy to achieve the grooves, since in particular the depth of the grooves can be precisely adjusted, so that the wood layer is completely cut through and the carrier film is not completely cut through.
Eine weitere günstige Variante sieht vor, dass vor dem Hinterspritzen der Dekorschicht die mindestens eine Nut mit einem Füllmaterial gefüllt wird. Dadurch kann zum Einen eine glatte Oberfläche der Dekorschicht einfacher erzielt werden. Zum Anderen kann durch die Wahl, insbesondere Farbe oder Transparenz des Füllmaterials, die durch die Nuten erzielten optischen Effekte noch weiter angepasst und verbessert werden.Another favorable variant provides that before the back of the decorative layer, the at least one groove is filled with a filling material. As a result, on the one hand, a smooth surface of the decorative layer can be achieved more easily. On the other hand, the choice, in particular color or transparency of the filling material, further optimizes and improves the optical effects achieved by the grooves.
Eine besonders günstige Variante sieht vor, dass das Füllmaterial aufgerakelt oder aufgespachtelt wird. Dadurch lassen sich die Nuten besonders einfach mit dem Füllmaterial füllen.A particularly favorable variant provides that the filling material is scrape or troweled. This makes it particularly easy to fill the grooves with the filling material.
Eine vorteilhafte Möglichkeit sieht vor, dass das Füllmaterial durchscheinend und/oder eingefärbt ist. Solche Füllmaterialien können einen besonders hochwertig anmutenden optischen Effekt auf der Dekorschicht erzielen. Ferner wird durch das Auffüllen der Nuten mit dem Füllmaterial die Dekorschicht stabilisiert, so dass bei einem späteren Umformprozess die notwendige Stabilität gegeben ist.An advantageous possibility provides that the filling material is translucent and / or colored. Such fillers can achieve a particularly high-quality visual effect on the decorative layer. Furthermore, by filling the grooves with the filling material, the decorative layer is stabilized, so that the necessary stability is given in a subsequent forming process.
Eine besonders vorteilhafte Möglichkeit sieht vor, dass die Dekorschicht vor dem Hinterspritzen des Substrats umgeformt wird. Dadurch kann die Dekorschicht z. B. an eine Wölbung des späteren Bauteiles angepasst werden.A particularly advantageous possibility provides that the decorative layer is formed before the back-molding of the substrate. As a result, the decorative layer z. B. be adapted to a curvature of the later component.
Eine günstige Lösung sieht vor, dass auf die Dekorschicht eine Schutzschicht aufgebracht wird. Eine solche Schutzschicht kann beispielsweise einen Kratzschutz oder Verschmutzungsschutz bieten. Insbesondere wird eine solche Schutzschicht durch einen transparenten Kunststoff, wie beispielsweise Lacke, gebildet.A favorable solution provides that a protective layer is applied to the decorative layer. Such a protective layer may offer, for example, scratch protection or contamination protection. In particular, such a protective layer is formed by a transparent plastic, such as paints.
