Description

Die Erfindung bezieht sich auf Fußbodenpaneel mit einem Schichtaufbau.The invention relates to floor panel with a layer structure.

Fußbodenpaneele, die aus Schichten aufgebaut sind, sogenannte Laminatfußböden, sind in großer Zahl bekannt. Sie bestehen meist aus einem Kem aus einer druckfesten Holzwerkstoffplatte (HDF oder MDF), einer Ausgleichsschicht, einer Schicht aus einem Dekorpapier und einer oberen verschleißfesten Schicht, die meist aus einem ausgehärteten, äußerst widerstandsfähigen Lack oder Harz besteht. Die Feuerfestigkeit dieser Fußbodenpaneele ist jedoch nur unzureichend gegeben.Floor panels, which are built up of layers, so-called laminate floors, are known in large numbers. They usually consist of a core of a pressure-resistant wood-based panel (HDF or MDF), a leveling layer, a layer of decor paper and an upper wear-resistant layer, which usually consists of a cured, highly resistant paint or resin. The fire resistance of these floor panels is given only insufficient.

Der Erfindung liegt somit die Aufgabe zugrunde, ein Fußbodenpaneel mit einer erhöhten Widerstandsfähigkeit gegen Feuer zu schaffen.The invention is therefore an object of the invention to provide a floor panel with increased resistance to fire.

Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The object is solved by the features specified in claim 1.

Durch die erfindungsgemäße feuerhemmende Schicht wird auf einfache Weise ein Fußbodenpaneel mit einer verbesserten Feuerfestigkeit geschaffen.The fire-retardant layer according to the invention easily creates a floor panel with improved fire resistance.

Zweckmäßigerweise besteht die feuerhemmende Schicht aus einem nicht brennbaren Material, unter Umständen kann jedoch auch ein schwer entflammbares Material eingesetzt werden.Conveniently, the fire retardant layer consists of a non-combustible material, but under certain circumstances, a flame-retardant material can be used.

Ein bevorzugtes Material für die feuerhemmende Schicht ist eine Fasermatte, insbesondere eine Glasfasermatte. Die Glasfasermatte hat den weiteren Vorteil, dass sie die Schlagfestigkeit des Fußbodenpaneels erhöht.A preferred material for the fire retardant layer is a fiber mat, especially a fiberglass mat. The glass fiber mat has the further advantage that it increases the impact resistance of the floor panel.

Wird die feuerhemmende Schicht mit einer Imprägnierung aus einem Bindemittel versehen, so wird die Anbindung an benachbarte Schichten verbessert. Ein bevorzugtes Imprägnierungsmittel ist Melaminharz, das üblicherweise zum Verbinden der Schichten von Fußbodenpaneelen untereinander eingesetzt wird.If the fire-retardant layer is provided with an impregnation of a binder, the connection to adjacent layers is improved. A preferred impregnating agent is melamine resin, which is commonly used to bond the layers of floor panels together.

Die feuerhemmende Schicht wird im Schichtaufbau des Fußbodenpaneels möglichst weit in Richtung auf die Oberseite angeordnet, da die Feuerbelastung in den überwiegenden Fällen von dieser Seite her erfolgt. Eine bevorzugte Anordnung der feuerhemmenden Schicht ist demnach zwischen einer Dekorschicht und einem Kern.The fire-retardant layer is arranged in the layer structure of the floor panel as far as possible in the direction of the top, since the fire load takes place in the majority of cases from this side. A preferred arrangement of the fire-retardant layer is therefore between a decorative layer and a core.

Die feuerhemmende Schicht sollte eine ausreichende Dicke aufweisen, um ihre feuerhemmende Wirkung zu entfalten. Bevorzugt ist eine Dicke zwischen 0,01 und 3 mm.The fire retardant layer should have sufficient thickness to develop its fire retardant effect. A thickness between 0.01 and 3 mm is preferred.

Das erfindungsgemäße Fußbodenpaneel erfordert nur unwesentliche Änderungen im Herstellungsprozess, da die erfindungsgemäß vorgesehene feuerhemmende Schicht problemlos zusammen mit anderen Schichten zum Fußboden paneel verpresst werden kann.The floor panel according to the invention requires only insignificant changes in the manufacturing process, since the inventively provided fire retardant layer can be easily pressed together with other layers to the floor panel.

Fig. 1 zeigt ein erfindungsgemäß ausgerüstetes Fußbodenpaneel 1. Die äußere Form und Gestalt des Fußbodenpaneels ist beliebig, das Fußbodenpaneel 1 kann beispielsweise als Brett oder Platte vorgesehen sein. Das erfindungsgemäße Fußbodenpaneel 1 ist im dargestellten Ausführungsbeispiel als rechteckige Platte ausgebildet, die an wenigstens zwei gegenüberliegenden Seiten mit einem mechanischen Verriegelungssystem 2 versehen ist. Im dargestellten Ausführungsbeispiel enthält das Verriegelungssystem 2 ein erstes Profil 2a und ein korrespondierendes zweites Profil 2b, die sich jeweils entlang gegenüberliegender Längskanten des Fußbodenpaneels 1 erstrecken und so ausgebildet sind, dass das erste Profil 2a eines Fußbodenpaneels und das zweite Profil 2b eines anliegenden, weiteren Fußbodenpaneels miteinander auf geeignete Weise so verbunden werden können, dass die Fußbodenpaneele 1 im Fußbodenverbund sowohl horizontal als auch vertikal verriegelt sind. Derartige mechanische Verriegelungsprofile sind in großer Zahl bekannt; und die Erfindung ist weder auf die spezielle Konstruktion der Verriegelungsprofile noch auf die spezielle Konstruktion irgendwelcher Verbindungselemente zwischen den einzelnen Fußbodenpaneelen 1 beschränkt. Vielmehr kann die Erfindung sowohl bei den dargestellten mechanischen Verriegelungssystemen als auch bei Verriegelungssystemen ohne horizontale Verriegelung, wie beispielsweise Nut- und Feder-Bretter, als auch bei Fußbodenpaneelen oder - platten ohne irgendwelche Verriegelungssysteme an den Rändem ausgebildet sein. Weiterhin können die Verriegelungssysteme, wie dargestellt, Profile an zwei gegenüberliegenden, oder aber an allen Seiten des Fußbodenpaneels aufweisen.Fig. 1 shows an inventively equipped floor panel 1. The outer shape and shape of the floor panel is arbitrary, the floor panel 1 may be provided for example as a board or plate. The floor panel 1 according to the invention is formed in the illustrated embodiment as a rectangular plate which is provided on at least two opposite sides with a mechanical locking system 2. In the illustrated embodiment, the locking system 2 includes a first profile 2a and a corresponding second profile 2b, each extending along opposite longitudinal edges of the floor panel 1 and are formed so that the first profile 2a of a floor panel and the second profile 2b of an adjacent, further floor panel can be connected to each other in a suitable manner so that the floor panels 1 are locked in the floor composite both horizontally and vertically. Such mechanical Locking profiles are known in large numbers; and the invention is not limited to the specific construction of the locking profiles nor to the special construction of any connecting elements between the individual floor panels 1. Rather, the invention can be formed on the edges both in the illustrated mechanical locking systems as well as locking systems without horizontal locking, such as tongue and groove boards, as well as floor panels or - plates without any locking systems. Furthermore, the locking systems, as shown, profiles on two opposite, or on all sides of the floor panel have.

Das Fußbodenpaneel 1 ist bevorzugt ein sogenanntes Laminat und enthält einen Schichtaufbau 3. Der Schichtaufbau 3 umfasst einen Kern 4, der bevorzugt eine Holzwerkstoffplatte höherer Festigkeit, wie beispielsweise eine HDF- oder eine MDF-Platte. Der Kern kann jedoch auch aus anderen zur Herstellung von Fußbodenpaneelen bekannten Materialien bestehen. Der Schichtaufbau 3 enthält weiterhin eine Dekorschicht 5. Die Dekorschicht 5 besteht meist aus einer Schicht aus Papier oder anderem Material, die ein aufgedrucktes oder anderweitig erzeugtes Dekor aufweist. Als Dekorschicht für das Fußbodenpaneel 1 der vorliegenden Erfindung kann jede im Stand der Technik bekannte Dekorschicht vorgesehen sein. Die Dekorschicht 5 ist bevorzugt durch eine Schutzschicht 6 abgedeckt. Als Schutzschicht 6 für das Fußbodenpaneel 1 der vorliegenden Erfindung kann jede bekannte Schutzschicht für Fußbodenpaneele eingesetzt werden, wie z.B. eine widerstandsfähige Lack- oder Harzbeschichtung.The floor panel 1 is preferably a so-called laminate and contains a layer structure 3. The layer structure 3 comprises a core 4, which preferably has a higher-strength wood-based panel, such as an HDF or an MDF panel. However, the core can also consist of other materials known for the production of floor panels. The layer structure 3 further contains a decorative layer 5. The decorative layer 5 usually consists of a layer of paper or other material having a printed or otherwise produced decor. As the decorative layer for the floor panel 1 of the present invention, any decor layer known in the art may be provided. The decorative layer 5 is preferably covered by a protective layer 6. As the protective layer 6 for the floor panel 1 of the present invention, any known protective layer for floor panels can be used, e.g. a durable paint or resin coating.

Der Schichtaufbau 3 des erfindungsgemäßen Fußbodenpaneels 1 enthält weiterhin eine feuerhemmende Schicht 7. Die feuerhemmende Schicht 7 besteht aus einem Material, das geeignet ist, das Entflammen der feuerabgewandten Seite des Paneels zu hemmen, d.h., je nach Brandeinwirkung, entweder zu verhindern oder stark zu verzögern. Durch die feuerhemmende Schicht 7 kann das Fußbodenpaneel 1 in eine höhere Brandschutzklasse (z.B. nach DIN EN13051 -1) klassifiziert werden, als dies bei einem Fußbodenpaneel ohne die Schicht 7 aber ansonsten mit gleichem Aufbau der Fall wäre. Bevorzugt besteht die feuerhemmende Schicht 7 aus einem nicht brennbaren Material. Die feuerhemmende Schicht 7 kann als Matte (Gewebe oder Vlies) aus Fasem, wie beispielsweise Glasfasern vorliegen. Die Dicke der feuerhemmenden Schicht 7 kann an den speziellen Anwendungszweck und/oder die gewünschte Brandschutzklassifikation und/oder die verwendeten Materialien angepasst werden und liegt bevorzugt zwischen 0,01 und 3 mm, insbesondere bevorzugt zwischen 0,05 bis 1 mm. Besonders bevorzugt wird als feuerhemmende Schicht 7 eine Glasfasermatte mit den folgenden Merkmalen eingesetzt.

The fire-retardant layer 7 is made of a material which is suitable to inhibit the flaming of the fire side facing away from the panel, ie, depending on the fire, either to prevent or greatly delay , By the fire-retardant layer 7, the floor panel 1 can be classified in a higher fire protection class (eg according to DIN EN13051 -1), as would be the case with a floor panel without the layer 7 but otherwise with the same structure. The fire-retardant layer 7 preferably consists of a nonflammable material Material. The fire-retardant layer 7 can be in the form of a mat (woven or nonwoven) of fibers, such as glass fibers. The thickness of the fire-retardant layer 7 can be adapted to the specific application and / or the desired fire protection classification and / or the materials used and is preferably between 0.01 and 3 mm, particularly preferably between 0.05 to 1 mm. Particularly preferred as the fire-retardant layer 7, a glass fiber mat with the following features is used. <b> TABLE 1 </ b> Product features and test methods property Reference to examination procedure unit Specification (nominal) grammage ISO 536 g / m 2 50 loss on ignition ISO 1887 % 22 tensile strenght md ISO 1924/2 N / 50 mm > 190 cmd N / 50 MM > 160 air porosity at 100 Pa l / m 2 / s 2000

Das Produkt besteht aus Glasfasern mit einer nominalen Länge von 6 mm und einem nominalen Durchmesser von 10 bis 11 µm. Die Glasfasermatte ist mit Polyvinylalkohol gebunden.The product consists of glass fibers with a nominal length of 6 mm and a nominal diameter of 10 to 11 μm. The fiberglass mat is bound with polyvinyl alcohol.

Die feuerhemmende Schicht 7 wird im Schichtaufbau 3 möglichst weit oben, d.h. möglichst nahe an der dem Raum, in dem das Fußbodenpaneel 1 verlegt wird, zugewandten Seite des Fußbodenpaneels 1 angeordnet. Im dargestellten Ausführungsbeispiel liegt die feuerhemmende Schicht 7 zwischen der Dekorschicht 5 und dem Kern 4; und ist vom Raum, in dem das Fußbodenpaneel 1 verlegt werden soll, lediglich durch die Deckschicht 6 und die Dekorschicht 5, die beide relativ dünn sind, getrennt. Auf diese Weise wird der dicke, brennbare Kern 4 optimal gegen einen Brand im Verlegungsraum abgeschirmt.The fire-retardant layer 7 is arranged in the layer structure 3 as far as possible, ie as close as possible to the space in which the floor panel 1 is laid, facing side of the floor panel 1. In the illustrated embodiment, the fire-retardant layer 7 is located between the decorative layer 5 and the core 4; and is separated from the room in which the floor panel 1 is to be laid, only by the cover layer 6 and the decorative layer 5, which are both relatively thin. In this way, the thick, combustible core 4 is optimally shielded against fire in the laying room.

Die feuerhemmende Schicht 7 erstreckt sich über die gesamte Breite des Kems 4 und endet jeweils an Stimseiten, dargestellt sind lediglich die gegenüberliegenden Stimseiten 4a, 4b, des Kems 4, die im fertigen Fußbodenbelag an entsprechende Stirnseiten der benachbarten Fußbodenpaneele anstoßen, so dass sich eine lückenlos über den Fußbodenbelag erstreckende, feuerhemmende Schicht 7 ausbildet.The fire-retardant layer 7 extends over the entire width of the core 4 and terminates in each case on end sides, only the opposite end sides 4a, 4b, of the core 4 are shown, which abut in the finished floor covering on corresponding front sides of the adjacent floor panels, so that a gapless over the floor covering extending, fire-retardant layer 7 is formed.

In Abwandlung des beschriebenen und gezeichneten Ausführungsbeispiels kann das Fußbodenpaneel 1 einen abweichenden Schichtaufbau 3 aufweisen, wobei beispielsweise weitere Schichten vorgesehen sein können. So können beispielsweise an der der Deckschicht 6 abgewandten Seite des Kems, im Kern oder oberhalb des Kems eine Trittschall-Dämmschicht vorgesehen sein. Es ist weiterhin denkbar, die feuerhemmende Schicht 7 als Dekorschicht und/oder sogar als Deckschicht auszubilden.In a modification of the described and drawn embodiment, the floor panel 1 may have a different layer structure 3, wherein, for example, further layers may be provided. For example, on the side of the core remote from the cover layer 6, a footfall sound insulation layer may be provided in the core or above the core. It is also conceivable to form the fire-retardant layer 7 as a decorative layer and / or even as a cover layer.

Das Material für die feuerhemmende Schicht 7 sollte bevorzugt so ausgewählt werden, dass die feuerhemmende Schicht möglichst wenig oder keine zusätzlichen Herstellungsschritte erfordert. Dies wird beispielsweise dadurch erreicht, dass die feuerhemmende Schicht 7, insbesondere wenn dafür eine Glasfasermatte eingesetzt wird, mit einer Imprägnierung versehen wird. Die Imprägnierung kann beispielsweise Melaminharz enthalten, das beim Herstellen von Fußboden paneelen als Imprägniermittel für die Dekorschicht verwendet wird. Durch die Verwendung des gleichen Imprägnierungsmittels für Dekor- und feuerhemmende Schicht ist es möglich, die feuerhemmende Schicht 7 zusammen beispielsweise mit der Dekorschicht 5 durch Anwendung von Druck und/oder Wärme mit dem Kern 4 zu verpressen. Dadurch wird kein zusätzlicher Befestigungsschritt zum Befestigen der feuerhemmenden Schicht 7 im Schichtaufbau 3 erforderlich. Die Imprägnierung der Matte, insbesondere der Glasfasermatte, mit Melamin oder einem anderen Mittel kann weiterhin zu einer Erhöhung der Festigkeit (z.B. gegen Eindrücken durch größere punktförmig aufgebrachte Lasten) führen. Es ist jedoch auch möglich, die feuerhemmende Schicht durch andere Maßnamen, z.B. durch Verkleben, im Schichtaufbau zu befestigen.The material for the fire-retardant layer 7 should preferably be selected such that the fire-retardant layer requires as little or no additional manufacturing steps as possible. This is achieved, for example, by providing the fire-retardant layer 7 with an impregnation, in particular if a glass-fiber mat is used for this purpose. The impregnation can contain, for example, melamine resin, which is used in the manufacture of floor panels as impregnating agent for the decorative layer. By using the same impregnating agent for decorative and fire retardant layer, it is possible to compress the fire retardant layer 7 together with, for example, the decorative layer 5 by applying pressure and / or heat to the core 4. As a result, no additional attachment step for attaching the fire-retardant layer 7 in the layer structure 3 is required. Impregnation of the mat, particularly the fiberglass mat, with melamine or other means may further result in an increase in strength (e.g., against impressions caused by larger punctiform loads). However, it is also possible to use the fire retardant layer by other measures, e.g. by gluing, in the layer structure to attach.
