Abstract

A composite element, specially for use as a floor mat in motor vehicles, consists of a load bearing core, made of a semi-rigid foam material such as polyurethane with a density from 50 to 300 kg/cu.m., and a cover layer with a high surface friction which is bonded to the core or foamed to it. The cover layer (1-5 mm thick) pref. consists of soft polyurethane foam, expanded or solid PVC, latex, reinforced by woven tissue and structured. This increases the friction between core and cover layer enough to prevent them from displacement relative to each other.

Description

VerbundkörperComposite body

Die Erfindung betrifft einen Verbundkörper aus einem tragenden Kern, insbesondere aus Schaumstoff, und einer Deckschicht.The invention relates to a composite body made of a load-bearing core, in particular made of foam, and a cover layer.

Beispielsweise bei Kraftfahrzeugen werden oft aus Gründen der Akustik und/oder der Erhöhung des allgemeinen Fahrkomforts Bodenmatten verwendet, die aus einem Polyurethan-Schaumstoff bestehen.In motor vehicles, for example, they are often used for reasons of acoustics and / or to increase the general driving comfort used floor mats made from consist of a polyurethane foam.

Auf diesem Formteil liegt dann die eigentliche Nutzschicht auf, beispielsweise einTegpich. Die Nutzschicht ist im Randbereich mechanisch an dem Formteil befestigt. Die Verbindung zwischen Nutzschicht und Formteil ist jedoch so schlecht, daß es zu einer Relativbewegung zwischen diesen beiden Schichten kommen kann, wodurch sich die Nutzschicht auf dem als Unterlage dienenden Formteil verschiebt.The actual wear layer then rests on this molded part, for example EinTegpich. The wear layer is mechanically attached to the molded part in the edge area. However, the connection between the wear layer and the molded part is so bad that it is can lead to a relative movement between these two layers, whereby the wear layer moves on the molding serving as a base.

Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Verbundkörper der angegebenen Gattung zu schaffen, bei dem die erwähnten Schwierigkeiten nicht mehr auftreten.The invention is therefore based on the object of a composite body of the specified genre, in which the difficulties mentioned do not exist occur more.

Insbesondere soll ein Formteil vorgeschlagen werden, bei dem die Deckschicht sich nicht mehr auf dem tragenden Kern verschieben kann.In particular, a molded part is to be proposed in which the cover layer can no longer move on the supporting core.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Deckschicht mit hohem Oberflächen-Reibungswert an den Kern angebracht ist.This object is achieved according to the invention in that a cover layer is attached to the core with a high surface friction coefficient.

Die mit der Erfindung erzielten Vorteile beruhen insbesondere darauf, daß die Reibung zwischen tragendem Kern und Deckschicht so hoch ist, daß sich diese beiden Schichten nur noch bei sehr ungünstiger Krafteinwirkung zueinander verschieben können, wodurch gewährleistet ist, daß die beiden Schichten ihre ursprüngliche Lage beibehalten.The advantages achieved with the invention are based in particular on that the friction between the supporting core and cover layer is so high that this Only move the two layers with respect to one another if the force is very unfavorable can, thereby ensuring that the two layers are in their original position maintained.

Obwohl im Prinzip die Deckschicht auch auf den tragenden Kern aufgeklebt werden kann, erfolgt nach einem bevorzugten Ausführungsraum die Verbindung zwischen Deckschicht und tragendem Kern durch Hinterschäumen der Deckschicht in einer Form. Wird die Deckschicht, beispielsweise durch Thermoformung oder durch Tiefziehen, vor dem eigentlichen Hinterschäumen bereits verformt, so können Verbundkörper mit starkem Verformungsgrad hergestellt werden.Although in principle the top layer is also glued to the load-bearing core can be, the connection between takes place according to a preferred execution space Cover layer and load-bearing core by back-foaming the cover layer in a mold. If the top layer, for example by thermoforming or deep drawing, Already deformed before the actual back-foaming, so composite bodies can with high degree of deformation.

Die Deckschicht kann aus einem Polyurethanweichschaumstoff, beispielsweise auf Ester- oder Ätherbasis oder einem sogenannten Kaltschaumsystem, aus einer profilierten und/oder strukturierten Kunststoffolie oder aus einer Schicht aus Latex oder latexiertem Trägerwerkstoff bestehen.The cover layer can consist of a flexible polyurethane foam, for example based on ester or ether or a so-called cold foam system, from a profiled and / or structured plastic film or from a layer of latex or latexed Carrier material exist.

Auch eine als Deckschicht dienende Polyurethan-Weichschaumstoffschicht und eine Latexschicht kann, beispielsweise durch Thermofixierung,mit einer Struktur- und/oder einem Profil versehen sein, um den Oberflächenreibungswert noch weiter zu erhöhen und damit die Rutschgefahr zu verringern.Also a flexible polyurethane foam layer serving as a cover layer and a latex layer can, for example by heat setting, with a structural and / or be provided with a profile to further increase the surface friction value to increase and thus reduce the risk of slipping.

Wird eine Deckschicht aus einem Polyurethan-Weichschaum verwendet, so kann ein sogenannter Polyurethan-Blockschaumstoff mit einer Dicke von 1 bis 5 mm eingesetzt werden.If a top layer made of a flexible polyurethane foam is used, a so-called polyurethane block foam with a thickness of 1 to 5 mm can be used.

Wird diese Deckschicht durch Hinter schäumen mit dem tragenden Kern verbunden, so muß die Deckschicht luft- bzw. schaumstoffundurchlässig sein. Zu diesem Zweck wird zwischen dem tragenden Kern und der Deckschicht eine entsprechend undurchlässige Sperrschicht angeordnet. Die dadurch erzielte Abdichtung führt gleichzeitig auch zu einer Wasserdichtigkeit des Verbundkörpers, wie sie für viele Anwendungsfälle angestrebt wird.This top layer is foamed back with the load-bearing core connected, the cover layer must be impermeable to air or foam. To this Purpose is between the load-bearing Core and the top layer one arranged accordingly impermeable barrier layer. The resulting seal at the same time also leads to a watertightness of the composite body, as it is for many use cases is sought.

Der bei der Hinterschäumung entstehende Schäumdruck reicht bis zu einem gewissen Verformungsgrad aus, um die Deckschicht der vorgegebenen Form anzupassen. Wenn die Verformung noch nicht stark genug bzw. aufgrund des Verformungsgrades durch den Schaumdruck keine ausreichende Formgebung möglich ist, kann die Deckschicht vor der Hinterschäumung durch Thermoformung oder Tiefziehen vorgeformt werden.The foaming pressure resulting from back-foaming reaches up to a certain degree of deformation in order to adapt the cover layer to the given shape. If the deformation is not strong enough or due to the degree of deformation If the foam pressure is insufficiently shaped, the top layer can be preformed by thermoforming or deep drawing prior to back foaming.

Obwohl für den tragenden Kern beispielsweise Polyäthylen, Polyvinylchlorid und andere Schaumkunststoffe eingesetzt werden können, wird nach einer bevorzugten Ausführungsform eine sogenannte halbharte Polyurethan-Qualität mit einer Rohdichte von 50 bis 300 kg/m3 verwensdet. Schließlich kann der tragende Kern bei Bedarf auch noch aus Fasermaterialien, beispielsweise einem imprägnierten/gepreßten Reißwoll-Verbundkörper bestehen.Although for the supporting core, for example, polyethylene, polyvinyl chloride and other foamed plastics can be used, according to a preferred one Embodiment a so-called semi-hard polyurethane quality with a bulk density from 50 to 300 kg / m3 used. Finally, the load-bearing core can also if necessary still made of fiber materials, for example an impregnated / pressed shredded wool composite exist.

Bei Bedarf können sowohl die Deckschicht als auch der tragende Kern, beispielsweise durch eine Gewebeeinlage, verstärkt werden, um die Festigkeit des Verbundkörpers zu erhöhen.If necessary, both the top layer and the load-bearing core, for example by a fabric insert, to increase the strength of the Increase composite body.
