Abstract
Mehrschichtigen Folienlaminat für eine Fahrzeuginnenverkleidung, welches mindestens eine oben liegende kompakte Dekorfolie aus thermoplastischem Material und eine darunter angeordnete Schaumschicht aufweist, wobei die Schaumschicht mindestens zwei Schaumlagen aufweist, die so angeordnet sind, dass die Dicke der Schaumschicht bereichsweise verändert ist.Multilayered film laminate for a vehicle interior trim, which has at least one upper compact decorative film of thermoplastic material and a foam layer arranged thereunder, the foam layer having at least two foam layers, which are arranged so that the thickness of the foam layer is changed in regions.
Description
Die Erfindung betrifft ein mehrschichtiges Folienlaminat, welches mindestens eine oben liegende kompakte Dekorfolie aus thermoplastischem Material als Deckfolie und eine darunter angeordnete Schaumschicht aufweist. The invention relates to a multilayer film laminate which has at least one top-lying compact decorative film of thermoplastic material as a cover film and a foam layer arranged thereunder.
Solche mehrschichtigen Folienlaminate, auch Schaumfolien genannt, mit einer äußeren Dekorfolie mit genarbter, gemusterter oder fein strukturierter Oberfläche, sind als Verkleidungen für die verschiedensten Gegenstände weithin bekannt und werden insbesondere verwendet für die Innenverkleidung von Fahrzeugen, hier oft als relativ weiche unterschäumte Folien mit angenehmer Haptik, etwa für die Verkleidung von Armaturenbrettern oder die Innenschalen von Türen etc. In entsprechender Anpassung von Festigkeit und Design werden solche Folienlaminate natürlich auch für andere hochwertig beschichtete Waren genutzt. Such multilayer film laminates, also called foam films, with an outer decorative film with a grained, patterned or finely textured surface, are widely known as linings for a variety of items and are used in particular for the interior lining of vehicles, often as relatively soft foamed films with a pleasant feel For example, for the paneling of dashboards or the inner shells of doors, etc. In appropriate adjustment of strength and design, such film laminates are of course used for other high-quality coated goods.
In aller Regel werden solche Folienlaminate auf die Oberfläche eines Trägers bzw. einer formstabilen Trägerstruktur aus hartem Kunststoff oder anderen Materialien aufgebracht, wobei die Schaumschichten eine weiche und angenehme Griffigkeit bzw. Haptik erzeugen. Da im Bereich des Automobilinterieurs ein starker Trend zur Verbesserung der Qualitätsanmutung zu beobachten ist, sind solche „fühlbaren“ Eigenschaften in zunehmendem Maße als Qualitätsmerkmal für Hersteller und Käufer entscheidend. In general, such film laminates are applied to the surface of a carrier or a dimensionally stable support structure made of hard plastic or other materials, wherein the foam layers produce a soft and pleasant feel or feel. Since there is a strong trend in the field of automotive interiors to improve the quality impression, such "tangible" properties are increasingly crucial as a quality feature for manufacturers and buyers.
Für die Herstellung solcher Folienlaminate wird eine Vielzahl von unterschiedlichen Verfahren angewendet, wie etwa das Kaschieren oder Laminieren, bei dem Schaumfolien, mittels Kleber oder auch durch Anschmelzen mit der Dekorfolie dauerhaft verbunden werden, oder auch das Umkehrstreichverfahren, bei dem die äußere Dekorschicht zunächst auf ein Trennpapier oder einen ähnlichen (Hilfs-)Träger gebracht, ausgehärtet und in einem zweiten Schritt auf die Schaumschicht kaschiert wird. For the production of such film laminates, a variety of different methods is used, such as lamination or laminating, are permanently connected to the foam sheets, by means of adhesive or by melting with the decorative film, or the reverse sweeping, in which the outer decorative layer on a first Release paper or a similar (auxiliary) carrier brought, cured and laminated in a second step on the foam layer.
Für die Herstellung von Folien für z. B. Türverkleidungen von Kraftfahrzeugen ist die Verwendung der im Stand der Technik bekannten Verfahren insofern zu überdenken, auch aus Umweltgründen, als bei der ansonsten kostengünstigen Kaschierung einer kompletten Türverkleidung doch erhebliche Mengen eines teuren Schaumlaminats in Türbereichen aufgebracht werden, in denen die angenehme Haptik und die weich hinterschäumten Folienbeschichtungen an sich gar nicht gebraucht werden. Benötigt wird die hohe Weichheit aus haptischen Gründen nur im Bereich der Türbrüstung, da dort die Wirkung und Haptik des Oberflächenmaterials durch den Endverbraucher wahrgenommen wird, nicht jedoch beispielsweise auf dem Türblatt im Fußraumbereich oder neben den Sitzpolstern. Letztlich verteuert sich bei den Herstellungsverfahren im Stand der Technik die Türbeschichtung in diesen vom Verbraucher unbeachteten Bereichen in unnötiger Weise. Selbstverständlich gibt es noch andere Bereiche im Kraftfahrzeug und bei übrigen Anwendungen, bei dem dasselbe Problem auftritt. So kann auch das Armaturenbrett eines KFZ oder LKW nur auf seiner Oberseite dicker und weich unterschäumt sein, während auf der dem Fußraum zugewandten Seite, wenn überhaupt, nur wenig Schaumdicke nötig ist. For the production of films for z. As door panels of motor vehicles, the use of known in the prior art method is to be re-considered, even for environmental reasons, as the otherwise cost-effective lamination of a complete door panel but considerable amounts of expensive foam laminate are applied in door areas where the pleasant feel and the Soft Foamed Foil coatings are not needed at all. The high softness is required for haptic reasons only in the area of the door sill, as there the effect and feel of the surface material is perceived by the end user, but not for example on the door leaf in the footwell area or next to the seat cushions. Finally, in the manufacturing processes in the prior art, the door coating becomes unnecessarily expensive in these areas unnoticed by the consumer. Of course, there are other areas in the automotive and other applications where the same problem occurs. Thus, even the dashboard of a car or truck can be foamed thicker and soft only on its upper side, while on the side facing the footwell, if any, only little foam thickness is needed.
Natürlich wurde dem bereits im Stand der Technik mit Lösungen begegnet, die etwa darin bestanden, eine zweiteilige Beschichtung von Türen vorzusehen. Soll z. B. die gesamte Tür mit Folie kaschiert und gleichzeitig die weiche Haptik nur im Bereich der Türbrüstung erreicht werden, muss die Brüstung der Tür, d.h. der obere und vom Fahrgast als Endkunden üblicherweise genutzte Bereich, mit einem weich hinterschäumten belegt sein, während das untere Türblatt etwa eine Spritzgussoberfläche erhält oder aber separat mit einer anderen und dünner hinterschäumten Folie versehen wird. Letzteres verursacht allerdings Mehrkosten durch die Bereitstellung einer zweiten Herstellungsanlage für das Türblatt und erfordert mit dem bei der Endmontage benötigten zweiten Fügeprozess einen zusätzlichen Prozessschritt. Of course, this has already been addressed in the prior art with solutions such as providing a two-part coating of doors. Should z. If, for example, the entire door is laminated with foil and at the same time the soft feel is only achieved in the area of the door sill, the parapet of the door, i. the upper and usually used by the passenger as the end user area, be covered with a soft foam behind, while the lower door leaf receives about an injection molding surface or is provided separately with a different and thin foam-backed film. The latter, however, causes additional costs by providing a second production line for the door leaf and requires an additional process step with the second joining process required in the final assembly.
Für die Erfindung bestand also die Aufgabe, ein mehrschichtiges Folienlaminat vorzuschlagen, welches in einzelnen Bereichen mit einer notwendigen oder erwünschten Griff-Weichheit versehen ist, während andere Bereiche mit gleicher Verkleidung lediglich dekorative Zwecke erfüllen, nach abriebspezifischen Kriterien gestaltet sind und keinen besonderen haptischen Anforderungen genügen müssen, und die einfach und mit den bewährten Verfahren ohne Probleme hergestellt werden können. For the invention, therefore, the object was to propose a multilayer film laminate, which is provided in some areas with a necessary or desirable grip softness, while other areas with the same panel only fulfill decorative purposes, are designed according to abrasion-specific criteria and do not meet any special haptic requirements need to be able to be produced easily and with the best practices.
Gelöst wird diese Aufgabe durch die Merkmale des Hauptanspruchs. Weitere vorteilhafte Ausbildungen sind in den Unteransprüchen offenbart. This object is achieved by the features of the main claim. Further advantageous embodiments are disclosed in the subclaims.
Dabei weist die Schaumschicht mindestens zwei Schaumlagen auf, die so angeordnet sind, dass die Dicke der Schaumschicht bereichsweise verändert ist. Dadurch entsteht eine Fahrzeuginnenverkleidung bzw. ein Verkleidungsteil mit einer über die Fläche oder Breite asymmetrisch hinsichtlich der Foliendicke geschäumten Folie. Damit wird z.B. bi einer Türverkleidung erreicht, dass der dickere Folienbereich auf dem Bereich einer Türbrüstung sich beschränkt und dort für die notwendige Weichheit sorgt, während der dünnere Folienbereich den Türbereich abdeckt, der ausschließlich dekorativen Ansprüchen genügen muss. Damit ergibt sich die Möglichkeit, eine kostengünstiges Verkleidungsteil mit einer Folienkonstruktion darzustellen, die die hochpreisigen Konstruktionselemente dort platziert, wo sie der Fahrzeugnutzer auch wahrnimmt, während die anderen Bereiche durch eine kostengünstige Basisversion dargestellt werden. In this case, the foam layer on at least two foam layers, which are arranged so that the thickness of the foam layer is changed in some areas. This results in a vehicle interior trim or a trim part with a foamed over the area or width asymmetrically with respect to the film thickness film. Thus, for example, a door trim is achieved so that the thicker film area is limited to the area of a door sill and provides the necessary softness there, while the thinner film area covers the door area, which only has to meet decorative requirements. This results in the opportunity to present a cost-effective trim part with a foil construction, which high-priced design elements placed where they perceive the vehicle user, while the other areas are represented by a low-cost basic version.
Eine vorteilhafte Weiterbildung besteht darin, dass Schaumlagen gleicher Dicke mindestens teilweise überlappend angeordnet sind. Dadurch ergibt sich eine besonders einfache Herstellbarkeit ohne aufwendige Veränderung der bisherigen Herstellprozesse. Gleiches gilt für eine weitere vorteilhafte Ausbildung, die darin besteht, dass Schaumlagen unterschiedlicher Dicke nebeneinander oder mindestens teilweise überlappend angeordnet sind. An advantageous development is that foam layers of the same thickness are arranged at least partially overlapping. This results in a particularly simple manufacturability without costly change in the previous manufacturing processes. The same applies to a further advantageous embodiment, which consists in that foam layers of different thickness are arranged side by side or at least partially overlapping.
Eine weitere vorteilhafte Ausbildung besteht darin, dass Schaumlagen aneinander angrenzend angeordnet sind. Hierdurch ergibt sich eine sehr einfache Form der Dickenanpassung und demzufolge eine einfachste Version der Herstellung des erfindungsgemäßen Folienlaminates. Eine weitere vorteilhafte Ausbildung besteht darin, dass Schaumlagen streifenförmig, vorzugsweise als Streifen gleicher Breite ausgebildet sind. Auch hier vereinfacht sich die Herstellung weiter dadurch, dass lediglich Schaumstreifen gleicher Breite aus Schaummaterial hergestellt zu werden brauchen, die dann nur noch entsprechend aufgelegt werden. A further advantageous embodiment is that foam layers are arranged adjacent to each other. This results in a very simple form of thickness adaptation and consequently a simplest version of the production of the film laminate according to the invention. A further advantageous embodiment is that foam layers are strip-shaped, preferably formed as strips of the same width. Again, the production further simplified by the fact that only foam strips of the same width need to be made of foam material, which are then placed only according to.
Eine weitere vorteilhafte Ausbildung besteht darin, dass einzelne Schaumlagen eine im Vergleich zu den übrigen Schaumlagen unterschiedliche Dichte aufweisen. Eine solche Ausbildung eröffnet die Möglichkeit, auch unterschiedliche Weichheiten bzw. Festigkeiten in für die Haptik wichtigen Bereichen bereitzustellen. A further advantageous embodiment is that individual foam layers have a different density compared to the other foam layers. Such a design opens up the possibility of also providing different softnesses or strengths in areas which are important for the feel.
Ein vorteilhaftes Verfahren zur Herstellung eines erfindungsgemäßen Folienlaminates besteht darin, dass ein bereits eine dünne Schaumschicht aufweisendes Folienlaminat auf der geschäumten Seite mit weiteren streifenförmigen Schaumlagen versehen wird. Hier ergibt sich eine Verbesserung des Herstellverfahrens im Sinne einer Integration der Fertigung der erfindungsgemäßen Fahrzeuginnenverkleidung in bestehende Fertigungslinien. Gleiches gilt für ein weiteres vorteilhaftes Verfahren zur Herstellung eines erfindungsgemäßen Folienlaminates, dass darin besteht, dass die kompakte Dekorfolie auf ihrer Unterseite mit mindestens zwei parallel zueinander aufgebrachten Schaumlagen/Schaumstreifen versehen wird, vorzugsweise während der Prägung der Außenseite der Dekorfolie. Das Aufbringen der Schaumlagen erfolgt dabei vorteilhafterweise durch Thermokaschierung oder Kleberkaschierung. Diese Verfahren sind überraschend gut geeignet und flexibel für die Verwendung bei der Herstellung von Schaum-Schaum-Verbindungen oder Schaum-Folien-Verbindungen. An advantageous method for producing a film laminate according to the invention is that a film laminate already having a thin foam layer is provided on the foamed side with further strip-shaped foam layers. This results in an improvement of the manufacturing process in the sense of integrating the production of the vehicle interior trim according to the invention in existing production lines. The same applies to a further advantageous method for producing a film laminate according to the invention, which consists in providing the compact decorative film on its underside with at least two foam layers / foam strips applied parallel to one another, preferably during the embossing of the outside of the decorative film. The application of the foam layers is advantageously carried out by thermal lamination or Kleberkaschierung. These processes are surprisingly well suited and flexible for use in the production of foam-foam compounds or foam-film compounds.
Besonders geeignet ist die Verwendung eines erfindungsgemäßen Folienlaminates für eine Fahrzeuginnenverkleidung zur Verkleidung von Kraftfahrzeugtüren oder Armaturenbrettern/Instrumententafeln, da hier der Unterschied zwischen z.B. Brüstungsbereich mit erforderlicher angenehmer Haptik und Fußbereich mit lediglich dekorativen Anforderungen besonders stark ausgeprägt ist und die erfindungsgemäße Fahrzeuginnenverkleidung hier die größten Effekte bei der Einsparung von Material und Kosten erreicht. Particularly suitable is the use of a film laminate according to the invention for a vehicle interior trim for the lining of motor vehicle doors or dashboards / dashboards, since the difference between e.g. Parapet area with required pleasant feel and foot area with only decorative requirements is particularly pronounced and the vehicle interior lining according to the invention here achieves the greatest effects in saving material and costs.
Durch die erfindungsgemäße Fahrzeuginnenverkleidung wird erstmalige eine hinsichtlich der Dicke asymmetrische Folienkonstruktion bereitgestellt. Sie erlaubt es bei der kundenseitigen Verarbeitung auf einem Trägermaterials zwei unterschiedliche Haptiken zu realisieren, ohne dass dazu zwei Bauteile generiert werden müssen. Dies spart Kosten hinsichtlich des kundenseitigen Prozesses durch den Entfall einer zweiten Werkzeugschiene und dem Entfall des Prozessschritts Fügen von Brüstung und Türblatt. Durch diese neue Folienkonstruktion eröffnen sich Möglichkeiten kundenseitig wieder auf vollkaschierte Türverkleidungen zurückzugreifen, anstatt z. B. nur Türbrüstungen zu kaschieren und das Türblatt als Spritzgussoberfläche darzustellen. By means of the vehicle interior lining according to the invention, for the first time a film structure which is asymmetrical in terms of thickness is provided. It allows two different haptics to be realized on one substrate during customer processing, without having to generate two components. This saves costs with regard to the customer-side process due to the omission of a second tool rail and the omission of the process step joining parapet and door leaf. This new foil construction opens up possibilities for customers to resort to fully laminated door panels, instead of z. B. only to hide door panels and represent the door leaf as an injection molding surface.
