Tiefziehfähige PlatteThermoformable plate

Die Neuerung betrifft eine tiefziehfähige Platte aus einem weichelastischen Verbundstoff.The innovation concerns a deep-drawable plate made of a flexible composite material.

Es ist bekannt, Formteilen durch einen in handwerklicher Arbeit hergestellten, mehrschichtigen Aufbau eine polsterartig weiche Oberfläche zu verleihen. Dabei wird auf das Formteil im allgemeinen in einem ersten Arbeitsgang zunächst eine Polsterschicht aus Textilfasern oder Schaumstoff aufgebracht. Anschließend wird das solcher Art entstandene Gebilde mit einem vorkonfektionierten Bezugsstoff bespannt, beispielsweise einem solchen aus textilem Material, in dem der Bezug in einer am fertigen Formteil nicht sichtbaren Zone angeheftet oder angeklebt wird.It is known that molded parts have a cushion-like structure by means of a multi-layer structure produced by hand to give a soft surface. The molding is generally done in a first step First a cushion layer made of textile fibers or foam is applied. Then it becomes such Art created structure covered with a prefabricated cover fabric, for example one from textile material in which the cover is attached or glued in a zone that is not visible on the finished molded part will.

Wegen der außerordentlich hohen Kosten eines solcher Art durchgeführten Fertigungsvorganges wurden verschiedeneBecause of the extremely high cost of such a type of manufacturing process, various

Versuche unternommen, ein Verbundmaterial, insbesondere zur Verkleidung in sich gewölbter Flachen zu entwickeln, dass einerseits ein in geschmacklicher Hinsicht ansprechendes Erscheinungsbild aufweist, das weichelastische Eigenschaften hat, und dabei durch einen einfach durchzuführenden Tiefziehvorgang vorgegebenen Konturen eines Formteiles angepaßt werden kann.Attempts have been made to develop a composite material, in particular for cladding curved surfaces, that, on the one hand, has an appealing appearance in terms of taste, the soft elastic properties has, and at the same time predetermined contours of a molded part by a deep-drawing process that is easy to carry out can be customized.

Diese Aufgabe wurde bisher nicht befriedigend gelöst. Beispielsweise in dem Bereich der KFZ-Innenausstattung ist es bis heute üblich, Blechteile mit einfachen Klebefolien zu überkleben oder eine mit Watte hinterfütterte Folie mit Hilfe von Klemmleisten, beispielsweise einem Fensterholm zu verankern. Desweiteren sind Techniken bekannt, bei denen eine Folie mit Zweikomponenten-Schaum hinterschäumt wird oder auf eine vorgeformte Pressfasermatte geklebt wird. Letzterer Aufbau zeigt keine weichelastische Eigenschaften.This task has not yet been solved satisfactorily. For example in the area of automotive interior equipment It is still common today to stick over sheet metal parts with simple adhesive films or one lined with cotton wool To anchor the foil with the help of clamping strips, for example a window stile. Then there are techniques known, in which a film is back-foamed with two-component foam or on a preformed pressed fiber mat is glued. The latter structure does not show any soft elastic properties.

Der Neuerung liegt die Aufgabe zugrunde, einen tiefziehfähigen Verbundstoff zu entwickeln, der weichelastische Eigenschaften mit einem geschmacklich ansprechenden Erscheinungsbild verbindet, und der dabei auf einfachste Weise beispielsweise an dem Tür- oder Fensterholm eines KFZ befestigt werden kann.The innovation is based on the task of creating a deep-drawable To develop composite material that has soft elastic properties with an appealing taste Appearance connects, and that in the simplest way, for example on the door or window pillar a car can be attached.

Diese Aufgabe wird neuerungsgemäß gelöst durch eine tiefziehfähige Platte aus einem weichelastischen Verbundstoff, der aus einer Schaumstoffbahn gebildet wird, die auf der einen Seite mit einer gegebenenfalls genarbten Deckschicht aus einem textlien oder aus einem Kunststoffflächengebilde kaschiert ist, während auf der anderen Seite eine gegebenenfalls durch eine Abdeckfolie geschützte Klebeschicht angeordnet ist.This object is achieved according to the invention by a deep-drawable Plate made of a flexible composite material, which is formed from a foam sheet that is on one side with an optionally grained cover layer made of a textile or a flat plastic structure is laminated, while on the other side a possibly protected by a cover film Adhesive layer is arranged.

Nach einer besonderen Ausgestaltung besteht die Schaumstoffplatte aus einem geschlossenzellig geschäumtenAccording to a special embodiment, the foam sheet consists of a closed-cell foamed sheet

Polyolefin, vorzugsweise aus einem peroxidisch vernetzten Polyäthylenschaum.Polyolefin, preferably from a peroxidic cross-linked polyethylene foam.

Die beigefügte Zeichnung (Fig.l) zeigt ein typisches Formteil aus der neuerungsgemäßen, tiefziehfähigen Platte. Diese besteht im wesentlichen aus der Schaumstoffbahn 1, die mit einer Deckschicht 2 aus einem textlien oder einem Kunststofflächengebilde tiefziehfähiger Qualität auf an sich bekannte Weise verbunden ist, beispielsweise durch Verklebung oder durch einen Flammkaschiervorgang .The attached drawing (Fig.l) shows a typical molded part from the innovation according to the deep-drawable plate. This consists essentially of the foam web 1 , which is connected to a cover layer 2 made of a textile or a plastic sheet of deep-drawable quality in a known manner, for example by gluing or by a flame lamination process.

Zur Vereinfachung des Montagevorganges hat es sich als zweckmäßig erwiesen, die Montagefläche der vorgefertigten Schaumstoffplatte mit einer Klebeschicht 4 aus einem aggressiven Kleber, insbesondere auf Acrylatbasis, zu versehen. Hinsichtlich der Auftragsweise dieser Klebeschicht ist es eine Frage der Zweckmäßigkeit, ob der Klebstoff ganzflächig, in einem Raster oder in Teilbereichen flächig aufgebracht wird. Zur Erhaltung der Klebrigkeit und ungehinderten Handhabung, wird die Klebstoffschicht im allgemeinen mit einer Abdeckfolie 3, vorzugsweise einer silikonierten PE-Folie abgedeckt. Um während des Tiefzieh-Prozesses ein sauberes Ausziehen der Schaumschicht zu erreichen, hat es sich als zweckmäßig erwiesen, eine feinperforierte PE-Folie zu verwenden.To simplify the assembly process, it has proven to be expedient to use the assembly surface of the prefabricated Foam board with an adhesive layer 4 made of an aggressive adhesive, in particular based on acrylate, too Mistake. With regard to the method of application of this adhesive layer, it is a question of expediency whether the adhesive is applied over the entire surface, in a grid or in partial areas. To maintain stickiness and unimpeded handling, the adhesive layer becomes generally covered with a cover film 3, preferably a siliconized PE film. To during the deep drawing process To achieve a clean removal of the foam layer, it has proven to be useful to use a finely perforated one Use PE film.

Formteile, die unter Verwendung der neuerungsgemäßen tiefziehfähigen Platte hergestellt sind zeichnen sich insbesondere dadurch aus, daß sie auf einfache Weise schnell montierbar sind. Sie haben einen polsterartig weichen Griff und können in außerordentlich weitem Rahmen speziellen geschmacklichen Wünschen in AussehenMolded parts that are made using the Deep-drawable plate are produced are characterized in particular by the fact that they are easy to use are quick to assemble. They have a soft, cushion-like feel and can go extremely far Framework special taste requirements in terms of appearance

und Aufbau angepaßt werden. In Abhängigkeit von der Art der verwendeten Deckschicht weisen sie eine hohe mechanische Widerstandskraft auf. Daneben kann es vorteilhaft sein, daß die Platte aufgrund ihres thermoplastischen Aufbaues schweißbar ist. Es ist dadurch beispielsweise auch möglich,einzelnen Wandzonen fertiger Formteile einen kompakten Aufbau zu geben und/oder beispielsweise Verstärkungsrippen auf solche Zonen aufzuschweißen.and structure can be adapted. Depending on the type of top layer used, they have a high mechanical resistance. In addition, it can be advantageous that the plate due to its thermoplastic Structure is weldable. It is thereby also possible, for example, to incorporate individual wall zones of finished molded parts to give a compact structure and / or, for example, to weld reinforcing ribs onto such zones.
