Description

Die Erfindung bezieht sich auf ein Fußbodenpaneel der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a floor panel explained in the preamble of claim 1 Art.

Fußbodenpaneele, die aus Schichten aufgebaut sind, sogenannte Laminatfußböden, sind in großer Zahl bekannt. Sie bestehen meist aus einem Kern 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.

Ein Fußbodenpaneel dieser Art ist aus der WO-A-97/47834 bekannt. Das bekannte Fußbodenpaneel weist einen Schichtaufbau auf, der jedoch keine feuerhemmende Schicht aufweist. Die Kantenbereiche sind mit einem Verdichtungsmittel beschichtet, das ein Imprägnierungsmittel, ein Porenfüller, ein Lack, ein Harz, ein Öl, ein Parafin oder ähnliches sein kann.A floor panel of this kind is from the WO 97/47834 known. The known floor panel has a layer structure, but does not have a fire-retardant layer. The edge portions are coated with a densifying agent, which may be an impregnating agent, a pore filler, a varnish, a resin, an oil, a paraffin or the like.

Die US 2003/0022577 beschreibt ein feuerhemmendes Paneel, bei dem alle Schichten des Schichtaufbaus feuerhemmend ausgebildet sind. Das Paneel enthält insbesondere Schichten mit einem Träger aus einem gewebten oder nicht gewebten Textilmaterial, wie beispielsweise Glasfaser, oder Papier, die feuerhemmend imprägniert sind, beispielsweise mit einem anorganischem Füllstoff mit Löß oder Melaminharz als Hauptbestandteil.The US 2003/0022577 describes a fire-retardant panel in which all layers of the layer structure are fire-retardant. In particular, the panel includes layers having a backing of a woven or non-woven fabric, such as glass fiber, or paper which is fire retardant impregnated, for example, with an inorganic filler having loess or melamine resin as the main component.

Die US 2002/0160680 beschreibt eine dekorative Laminateinheit, die zum Aufbringen auf ein festes Substrat, beispielsweise aus Faserzement, ausgebildet ist. Die dekorative Einheit oder das Decklaminat enthält eine Oberflächenschicht, die abrasive Partikel enthält und mit Melaminharz imprägniert ist, eine darunterliegende dekorativ bedruckte Schicht, die unbehandelt sein kann, und eine Kernschicht, die mindestens eine Lage aus einem PETG-Grundstoff enthält.The US 2002/0160680 describes a decorative laminate unit designed for application to a solid substrate, for example fiber cement. The decorative unit or cover laminate contains a surface layer that contains abrasive particles and is impregnated with melamine resin, an underlying decorative printed layer that is untreated and a core layer containing at least one layer of a PETG base.

Die GB 2 053 798 beschreibt einen Schichtaufbau, bei dem wiederum die obere Schicht aus einem Harz imprägnierten Glasfasergewebe besteht. Unterhalb dieser Glasfaserschicht ist eine dünne Metallfolie vorgesehen, die zwar selbst nicht brennbar ist, jedoch die Wärme sehr schnell und vollständig in das brennbare Substrat einleitet; die Feuerhemmung muss somit durch die Deckschicht erzielt werden.The GB 2 053 798 describes a layer structure in which again the upper layer consists of a resin impregnated glass fiber fabric. Below this glass fiber layer, a thin metal foil is provided which, although not flammable itself, but introduces the heat very quickly and completely into the combustible substrate; The fire retardation must therefore be achieved through the cover layer.

Die EP 1 493 878 beschreibt ein Fußbodenpaneel mit einem mechanischen Verriegelungssystem, einer Dekorschicht und einem Kern aus einem Holzwerkstoff. Es ist weiter eine kaltkeramische Beschichtung vorgesehen, die gute feuerhemmende Eigenschaften aufweist. Diese Beschichtung ist jedoch auf der Unterseite des Kerns vorgesehen, und befindet sich an einer Stelle, die keine Stoßkante zum benachbarten Bodenpaneel bildet.The EP 1 493 878 describes a floor panel with a mechanical locking system, a decorative layer and a core of wood-based material. It is further provided a cold-ceramic coating, which has good fire retardant properties. However, this coating is provided on the underside of the core, and is located at a location that does not form an abutting edge to the adjacent floor panel.

Die EP 1 593 791 beschreibt einen brandbeständigen, plattenförmigen Werkstoff, der mindestens eine Trägerlage aus Holzwerkstoff und eine feuerhemmende Außenlage aufweist. Die Außenlage kann auch eine dekorative Beschichtung sein.The EP 1 593 791 describes a fire-resistant, plate-shaped material having at least one carrier layer of wood material and a fire-retardant outer layer. The outer layer can also be a decorative coating.

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, wobei durch die Kombination der feuerhemmenden Schicht mit einer feuerhemmenden Beschichtung zumindest an den Stoßkanten eine durchgehende Feuerhemmung erreicht wird.The fire retardant layer according to the invention provides a floor panel with improved fire resistance in a simple manner, with the fire retardant being achieved by combining the fire retardant layer with a fire retardant coating at least at the abutting edges.

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

Die Beschichtung der feuerhemmend ausgebildeten Kante erfolgt bevorzugt mit einer Mischung aus Kaolin und Natriumsilikat, und wird bevorzugt durch Aufspritzen aufgebracht.The coating of the fire-retardant edge is preferably carried out with a mixture of kaolin and sodium silicate, and is preferably applied by spraying.

Fig. 1 zeigt ein Fußbodenpaneel 1, welches nicht erfindungsgemäß ausgebildet ist und das Verständnis der Erfindung erleichtert. Die äußere Form und Gestalt des Fußbodenpaneels ist beliebig, das Fußbodenpaneel 1 kann beispielsweise als Brett oder Platte vorgesehen sein. Das erfindungsgemäße Fußbodenpaneel ist 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 ausgebildet sein. Weiterhin können die Verriegelungssysteme, wie dargestellt, Profile an zwei gegenüberliegenden, oder aber an allen Seiten des Fußbodenpaneels aufweisen. Fig. 1 shows a floor panel 1, which is not formed according to the invention and facilitates the understanding of the invention. 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 according to the invention is designed as a rectangular plate, which on at least two opposite sides with a mechanical locking system 2 is provided. 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 both in the illustrated mechanical locking systems as well as locking systems without horizontal locking, such as tongue and groove boards. 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 aus einer Holzwerkstoffplatte höherer Festigkeit, wie beispielsweise eine HDF- oder eine MDF-Platte. 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 made of a wood-based panel of higher strength, such as an HDF or an MDF board. 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 Fasern, 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. TABELLE 1 Produktmerkmale und Prüfungsverfahren Eigenschaft Bezugnahme auf Prüfungsverfahren Einheit Spezifikation (nominal) Flächengewicht ISO 536 g/m2 50 Glühverlust ISO 1887 % 22 Zugfestigkeit md ISO 1924/2 N/50 mm >190 cmd N/50 MM >160 Luftporosität bei 100 Pa l/m2/S 2000 The layer structure 3 of the floor panel 1 according to the invention further comprises a fire-retardant layer 7. The fire-retardant layer 7 is made of a material which is suitable for inhibiting the flaming of the fire side facing away from the panel, ie, depending on the exposure to fire, either to prevent or greatly delay. Through 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. Preferably, the fire-retardant layer 7 is made of a non-combustible material. The fire retardant layer 7 may be present as 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, d. h. 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, ie between the decorative layer 5 and the core 4; and is from the room in which the floor panel 1 is to be laid, only through the cover layer 6 and the decorative layer 5, which are both relatively thin, separated. 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 Kerns 4 und endet jeweils an Stirnseiten, dargestellt sind lediglich die gegenüberliegenden Stirnseiten 4a, 4b, des Kerns 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 ends at end faces, shown are only the opposite end faces 4a, 4b, the core 4, which abut in the finished floor covering to corresponding end faces of the adjacent floor panels, so that a gapless over the floor covering extending, fire-retardant layer 7 is formed.

Wie Fig. 3 zeigt, wird erfindungsgemäß die feuerhemmende Ausgestaltung des Fußbodenpaneels noch verbessert werden, indem zumindest Bereiche der Kanten 8 des Fußbodenpaneels feuerhemmend (brandverzögernd oder feuerfest) ausgestaltet werden. Die Kanten 8 sind die Seitenflächen des Fußbodenpaneels, die sich um den Umfang des Fußbodenpaneels herum erstrecken und im fertigen Fußbodenbelag eine im Wesentlichen vertikale Ausrichtung aufweisen. Die Kanten 8 enthalten insbesondere einen Stoßkantenbereich 8a, der sich unmittelbar an die Deck- bzw. Dekorschicht 5, 6 anschließt und bevorzugt senkecht dazu verläuft. Die Stoßkantenbereiche 8a liegen im fertigen Fußbodenbelag an korrespondierenden Stoßkantenbereichen benachbarter Paneele an. Die Kante 8 enthält jedoch weiterhin die Profile 2a, 2b des Verbindungssystems, die auch Flächen umfassen können, die eine horizontale oder schräge Ausrichtung aufweisen.As Fig. 3 shows, according to the invention, the fire-retardant design of the floor panel can be further improved by at least portions of the edges 8 of the floor panel fire retardant (fire-retardant or flame retardant) are configured. The edges 8 are the side surfaces of the floor panel which extend around the periphery of the floor panel and have a substantially vertical orientation in the finished floor covering. The edges 8 contain, in particular, an abutting edge region 8a, which adjoins directly the covering or decorative layer 5, 6 and preferably extends perpendicularly thereto. The abutting edge regions 8a abut in the finished floor covering at corresponding abutting edge regions of adjacent panels. However, the edge 8 still contains the profiles 2a, 2b of the connection system, which may also comprise surfaces having a horizontal or oblique orientation.

Um die feuerhemmende Ausgestaltung im Stoßbereich zwischen benachbarten Paneelen zu verbessern, d.h. ein Durchschlagen der Flammen in die Stoßfuge zwischen benachbarten Paneelen zu verhindern, wo sie die feuerhemmende Schicht umgehen könnten, ist die Kante 8 erfindungsgemäß feuerhemmend ausgebildet. Dies wird durch eine feuerhemmende Beschichtung 9 erreicht, die zumindest bereichsweise auf die Kante 8, bevorzugt rundum das Fußbodenpaneel 1 herum, aufgebracht wird. Die Beschichtung sollte auf jeden Fall denjenigen Bereich der Kante 8 bedecken, der der Richtung der mutmaßlichen Feuerbelastung zugewandt ist, d.h. der Stoßkantenbereich 8a. Es ist jedoch bevorzugt, dass die Beschichtung 9 auch auf anderen Bereichen der Kante 8 aufgebracht wird, insbesondere auf die nach oben, d.h. in Richtung auf die Deck- und Dekorschicht 5, 6, weisenden Flächen der Verbindungsprofile 2a, 2b und auf alle anderen, sich an den Stoßkantenbereich 8a anschließenden Bereiche. Bei Kanten 8, die nicht mit Verbindungsprofilen versehen sind, ist es bevorzugt, dass die Beschichtung 9 die gesamte Kante von der Dekor- und Deckschicht 5, 6 bis zur Unterseite bedeckt. Aber auch an Kanten 8, die ein Verbindungsprofil zeigen, erhöht es die Sicherheit gegen ein Durchschlagen der Flammen, wenn alle Bereiche der Kante 8 mit der Beschichtung 9 versehen sind.In order to improve the fire-retardant configuration in the joint area between adjacent panels, ie to prevent penetration of the flames into the butt joint between adjacent panels, where they could bypass the fire-retardant layer, the edge 8 according to the invention is fire-retardant. This is achieved by a fire-retardant coating 9, which is at least partially applied to the edge 8, preferably around the floor panel 1 around. The coating should in any case cover that portion of the edge 8 which faces the direction of the presumed firing load, ie the abutting edge region 8a. However, it is preferred that the coating 9 is applied to other areas of the edge 8, in particular to the upwardly, ie in the direction of the cover and decorative layer 5, 6, facing surfaces of the connecting profiles 2a, 2b and on all others, at the abutting edge region 8a subsequent areas. For edges 8, which are not provided with connecting profiles it is preferred that the coating 9 cover the entire edge of the decorative and cover layer 5, 6 to the bottom. But even at edges 8, which show a connection profile, it increases the security against penetration of the flames, when all areas of the edge 8 are provided with the coating 9.

Die Beschichtung 9 liegt bevorzugt als mehr oder weniger viskose Flüssigkeit vor, so dass sie durch Versprühen oder Verspritzen, Streichen, Rollen oder andere Beschichtungsverfahren aufgebracht werden kann. Im dargestellten Ausführungsbeispiel wird die Beschichtung 9 mit Hilfe zweier Sprühdüsen 10 aufgebracht, die schräg von oben her auf die Kante 8 gerichtet sind, so dass die Beschichtung 9 in einer Richtung aufgebracht wird, die der Richtung der Feuerbeaufschlagung angenähert ist, so dass sichergestellt werden kann, dass alle möglicherweise einer Feuerbeaufschlagung ausgesetzten Bereiche der Kante 8 auch mit dem Beschichtungsmittel 9 bedeckt werden.The coating 9 is preferably present as a more or less viscous liquid, so that it can be applied by spraying or spraying, brushing, rolling or other coating methods. In the illustrated embodiment, the coating 9 is applied by means of two spray nozzles 10, which are directed obliquely from above onto the edge 8, so that the coating 9 is applied in a direction which approximates the direction of the fire application, so that it can be ensured in that all possibly exposed regions of the edge 8 are also covered with the coating agent 9.

Als Beschichtungsmittel eignet sich jedes bekannte, in fließfähiger Form aufzubringende, feuerhemmende Mittel. Bevorzugt enthält das Beschichtungsmittel 9 eine Mischung aus Kaolin und Natriumsilikat in wässriger Lösung. Sowohl Kaolin als auch Natriumsilikat sind im Handel erhältlich und können in handelsüblicher Reinheit und Zusammensetzung eingesetzt werden. Die Beschichtungsmenge pro Flächeneinheit hängt von der Saugfähigkeit des Untergrunds und von anderen Faktoren ab, und kann auf einfache Weise experimentell bestimmt werden. Im Prinzip kann jedoch zur Kantenbeschichtung jedes Material eingesetzt werden, das auch bei einer relativ dünnen Schichtdicke (damit der Stoß zwischen benachbarten Paneelen im Fußbodenbelag nicht zu groß und störend sichtbar wird) eine den Normen (beispielsweise EN 13501-1 oder EN ISO 9239-1) genügende Feuerhemmung aufweist.As a coating agent, any known, to be applied in flowable form, fire retardant agent. The coating composition 9 preferably comprises a mixture of kaolin and sodium silicate in aqueous solution. Both kaolin and sodium silicate are commercially available and can be used in commercial purity and composition. The amount of coating per unit area depends on the absorbency of the substrate and other factors, and can be easily determined experimentally. In principle, however, any material can be used for the edge coating which, even with a relatively thin layer thickness (so that the impact between adjacent panels in the floor covering does not become too large and disturbing), meets the standards (for example EN 13501-1 or EN ISO 9239-1 ) has sufficient fire retardancy.

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 Kerns, im Kern oder oberhalb des Kerns eine Trittschall-Dämmschicht vorgesehen sein. Derartige Ausführungsformen lassen sich nicht den Ansprüchen unterordnen und gehören nicht zur Erfindung.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 facing away from the cover layer 6, a footfall sound insulation layer may be provided in the core or above the core. Such embodiments can not be subordinated to the claims and are not part of the invention.

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 Fußbodenpaneelen 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 may 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.
