Mehrschichtiges Folienlaminat Multilayer film laminate
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 Such multilayer film laminates, also called foam films, with an outer decorative film with a grained, patterned or finely textured surface are as
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. Cladding for a variety of items well known and are used in particular for the interior trim of vehicles, often as a relatively soft foamed films with a pleasant feel, such as for the paneling of dashboards or the inner shells of doors etc. In appropriate adjustment of strength and design are such Film laminates of course also 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 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 grip or feel. There is a strong trend towards improving the automotive industry
Qualitäts anmutung zu beobachten ist, sind solche„fühlbaren" Eigenschaften in Quality impression is observed, are such "tactile" properties in
zunehmendem Maße als Qualitätsmerkmal für Hersteller und Käufer entscheidend. increasingly as a quality feature for manufacturers and buyers crucial.
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 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 first placed on a release paper or similar (auxiliary) carrier, cured and second step is laminated to 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 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. What is needed is the high
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 Softness for haptic reasons only in the area of the door sill, since 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
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. 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 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 footwell side facing, if any, little foam thickness is needed. 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 the passenger as
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. 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. End customer usually used area, be covered with a soft foam-backed, 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. For the invention, therefore, the object was to propose a multilayer film laminate, which is provided in some areas with a necessary or desirable handle-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. This is e.g. In the case of a door trim, the thicker film area on the area of a door sill is limited and provides the necessary softness, while the thinner film area covers the door area, which only has to meet decorative requirements. This gives rise to the possibility of presenting a cost-effective trim part with a film construction, which places the high-priced construction elements where it perceives 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. 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 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. 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

By fiction, contemporary vehicle interior trim is provided for the first time in terms of thickness asymmetric film construction. It allows two different haptics to be realized on one substrate during customer processing, without having to generate two components. This saves costs in terms of the customer process by the elimination of a second

Schaumschicht 3 aufweist. Die Schaumschicht weist zwei Schaumlagen 4, 5 aufweist, die so angeordnet sind, dass die Dicke der Schaumschicht bereichsweise verändert ist. Die Unterseite des Folienlaminats ist auf einem hier nicht näher dargestellten Träger aufgebracht. Durch die im Wesentlichen eben ausgebildete Fläche des Trägers des Folienlaminats ergibt sich hier in den verdickten Schaumbereichen eine Wölbung der Dekorfolie nach außen, also zum Betrachter / zum Fahrzeuginsassen hin. Im linken Teil 6 des Schnittbereiches beträgt die Dicke der aus zwei überlappenden Schaumlagen 4, 5 bestehenden Foam layer 3 has. The foam layer has two foam layers 4, 5, which are arranged so that the thickness of the foam layer is changed in some areas. The underside of the film laminate is applied to a carrier, not shown here. As a result of the essentially flat surface of the carrier of the film laminate, a curvature of the decorative film results here in the thickened foam regions, ie towards the viewer / vehicle occupant. In the left part 6 of the cutting area, the thickness of the two overlapping foam layers 4, 5 existing
Schaumschicht 3 insgesamt maximal 2,3 mm, während die Mindestdicke der aus nur einer Schaumlage 4 bestehenden Schaumschicht 3 im rechten Teil 7 des Schnittbereiches nur insgesamt ca. 0,8 mm beträgt. Foam layer 3 a maximum of 2.3 mm, while the minimum thickness of only one foam layer 4 existing foam layer 3 in the right part 7 of the cutting area only a total of about 0.8 mm.
Die Schaumlagen 4 und 5 sind hier Schaumlagen gleicher Dicke, wobei die Schaumlage 4 rechten Teil 7 des Schnittbereiches durch Walz und Prägevorgänge der Dekorfolie 2 stärker komprimiert wurde als dies linken Teil 6 des Schnittbereiches der Fall ist. The foam layers 4 and 5 are here foam layers of the same thickness, wherein the foam layer 4 right portion 7 of the cutting area by rolling and embossing operations of the decorative film 2 was compressed more than this left part 6 of the cutting area is the case.
Fig. 2 zeigt ein mehrschichtiges Folienlaminat 8 für eine Fahrzeuginnen Verkleidung im Schnitt durch einen Dickenübergangsbereich, bei der unter die unter einer Dekorfolie 9 angeordnete Schaumschicht 10 aus Schaumlagen 11, 12 besteht, die als Streifen gleicher Breite ausgebildet und unter Bildung eines Spaltes aneinander angrenzend angeordnet sind.
