Description

Die Erfindung betrifft ein Fußbodenpaneel, insbesondere für einen Laminatfußboden, mit einer dekorativen Schicht und einem Overlaypapier, das eine Zellstoffschicht aufweist.The invention relates to a floor panel, in particular for a laminate floor, with a decorative layer and an overlay paper having a pulp layer.

Fußbodenpaneele der eingangs genannten Art sind insbesondere Bestandteile von Dekorlaminaten und werden beispielsweise in der EP 0 875 399 A2 offenbart. Dieses vorbekannte Fußbodenpaneel zeichnet sich insbesondere durch eine hohe Homogenität der räumlichen Verteilung der Harzstoffpartikel und deren besondere Konzentrierung in der sogenannten Verschleifschicht, d. h. in einer die Dekorbahn nach außen abschließenden einen hitzehärtbaren Kunstharz enthaltende Schicht, aus. Für die Güte von derartigen Dekorlaminaten sind Eigenschaften wie Abriebfestigkeit und Abnutzungsbeständigkeit von nicht geringer Relevanz. Eine optimale Darstellung des Dekors wird nur dann erhalten, wenn die zur Produktion eingesetzten Overlayfilme eine hohe Transparenz sicherstellen.Floor panels of the type mentioned are in particular components of decorative laminates and are used for example in the EP 0 875 399 A2 disclosed. This known floor panel is characterized in particular by a high homogeneity of the spatial distribution of the resin particles and their particular concentration in the so-called Verschleifschicht, ie in a the decorative sheet outwardly final a thermosetting resin-containing layer from. For the quality of such decorative laminates properties such as abrasion resistance and wear resistance are of no relevance. An optimal representation of the decoration is only obtained if the overlay films used for production ensure a high transparency.

Ein aus dem Stand der Technik bekannter Aufbau eines Fußbodenpaneels gestaltet sich derart, dass als oberste Schicht ein mit Melaminharzen imprägniertes so genanntes Overlay-Papier dient. Unter dieser obersten Schicht befindet sich ein imprägniertes bedrucktes Papier, welches die dekorative Schicht des fertigen Fußbodenpaneels bildet und auf der als Träger dienenden Holzwerkstoffplatte sitzt. Das Fußbodenpaneel schließt mit einem mit Melamin- und/oder Hartstoffharzen imprägnierten Gegenzugpapier ab, das auf die Rückseite der Holzwerkstoffplatte aufgepresst ist und dessen Funktion es ist, durch einen symmetrischen Aufbau des Fußbodens ein Verziehen und Schüsseln der fertigen Fußbodenpaneele zu verhindern.A known from the prior art construction of a floor panel designed such that serves as the top layer impregnated with melamine resins so-called overlay paper. Below this uppermost layer is an impregnated printed paper, which forms the decorative layer of the finished floor panel and sits on the wood-based panel serving as a support. The floor panel closes with a with melamine and / or hard resins impregnated backing paper, which is pressed onto the back of the wood-based panel and its function is to prevent warping and bowls of the finished floor panels by a symmetrical construction of the floor.

Um die geforderte Abriebfestigkeit solcher Laminate zu verbessern, ist man dazu übergegangen, Korundpartikel in das Overlaypapier einzubringen. Nach dem Flüssigoverlay-Verfahren, welches heute das Hauptherstellungsverfahren für derartige Overlays darstellt, werden die für die hohe Abriebresistenz verantwortlichen Korundpartikel unterhalb der Zellstoffschicht des Overlay-Basispapiers angebracht. Hierdurch ergibt sich der Vorteil, dass die zur Verpressung der einzelnen Lagen des Laminatboden eingesetzten Pressbleche nicht durch die Korundpartikel im Overlayfilm beschädigt werden können, da sich zwischen Pressblech und Korund eine schützende Zellstofflage befindet.In order to improve the required abrasion resistance of such laminates, it has begun to introduce corundum particles in the overlay paper. After the liquid overlay process, which is today the main production process for such overlays, the corundum particles responsible for the high abrasion resistance are applied below the pulp layer of the overlay base paper. This has the advantage that the for pressing the individual layers of the Laminated floor used press plates can not be damaged by the corundum particles in the overlay film, as there is a protective pulp layer between press plate and corundum.

Die Position der Korundpartikel im Overlay wird also dadurch bestimmt, dass sie zum einen die dekorative Druckschicht vor Durchrieb schützen müssen, andererseits aber auch zum Schutz der empfindlichen Pressbleche einen möglichst großen Abstand zur eigentlichen Oberfläche des fertigen Laminatbodens haben sollen.The position of the corundum particles in the overlay is thus determined by the fact that on the one hand they have to protect the decorative print layer against abrasion, but on the other hand they should also have the greatest possible distance from the actual surface of the finished laminate floor to protect the sensitive press plates.

In den letzten Jahren sind die Anforderungen an das Design der Laminatfußböden beträchtlich gestiegen. Dies betrifft nicht nur den eigentlichen Dekordruck, sondern auch die über den Pressprozess und damit über das Pressblech vermittelten Eigenschaften der Laminatoberfläche. Zu nennen ist hier neben einer mit dem Druckbild synchronisierten Holzporenstruktur sowie einer stärker reliefartigen Oberflächen (sog. Handscraped-Designs) auch der Glanzgrad der Oberfläche, der von matt bis zu stark glänzend variieren kann.In recent years, the demands on the design of laminate flooring have increased considerably. This not only affects the actual decor pressure, but also the properties of the laminate surface conveyed by the pressing process and thus by the press plate. In addition to a wood pore structure synchronized with the printed image as well as a more relief-like surface (so-called hand-scraped designs), the degree of gloss of the surface, which can vary from dull to highly lustrous.

Insbesondere hinsichtlich des Glanzgrades besteht die Anforderung der Laminatbodenhersteller, dass die Laminatbodenoberfläche eine Scheuer- oder Mikrokratzbeständigkeit aufweisen soll. Hierdurch werden feine Kratzer auf der Oberfläche vermieden, die bereits während der Fertigung und des Transports zum Endkunden entstehen können und die insbesondere auf dunklen Dekoren störend auffallen. Zudem haben solche Produkte den Vorteil, dass sie sich auch während der Nutzung weniger stark im Glanzgrad verändern. Typische Nutzungsspuren und Glanzgradveränderungen auf stark belaufenen Fußbodenbereichen werden hierdurch vermieden. Glänzende Oberflächen werden durch Mikrokratzer weit weniger mattiert, matte Oberflächen werden weit weniger durch die Nutzung aufpoliert.In particular, in terms of gloss level, there is a requirement of laminate flooring manufacturers that the laminate floor surface should have a scrub or micro scratch resistance. As a result, fine scratches on the surface can be avoided, which can already arise during manufacture and transport to the end customer and attract attention especially on dark decors. In addition, such products have the advantage that they change less during the use of the gloss level. Typical signs of wear and gloss changes on heavily used floor areas are thereby avoided. Glossy surfaces are less matted by micro-scratches, matt surfaces are much less polished by the use.

Ähnliche Anforderungen nach einer besseren Mikrokratz- oder Scheuerbeständigkeit werden auch an Möbeloberflächen gestellt. Obwohl hier ein anderer Aufbau der Oberfläche vorhanden ist und normalerweise keine Overlays zum Schutz des Dekorfilms zum Einsatz kommen, so lässt sich das von uns eingesetzte Prinzip zur Erhöhung der Scheuerbeständigkeit auch hier sehr gut einsetzen.Similar requirements for a better micro scratch or abrasion resistance are also placed on furniture surfaces. Although there is a different surface structure and usually no overlays are used to protect the decorative film, the principle we use to increase the abrasion resistance can also be used very well here.

Es ist daher Aufgabe der Erfindung, ein Fußbodenpaneel der eingangs genannten Art zur Verfügung zu stellen, das den Anforderungen an den Overlayfilm nach Abriebfestigkeit und Pressblechschutz einerseits und Mikrokratz- oder Scheuerbeständigkeit andererseits besser Genüge leistet.It is therefore an object of the invention to provide a floor panel of the type mentioned that the requirements on the overlay film for abrasion resistance and pressure plate protection on the one hand and micro scratch or abrasion resistance on the other hand makes better enough.

Im Hinblick auf die Herstellung einer scheuerfesten Möbeloberfläche ist es Aufgabe der Erfindung, ein harzimprägniertes Dekorpapier zur Verfügung zu stellen, dass eine gute Scheuer- und Mikrokratzbeständigkeit aufweist, ohne die Pressbleche in Mitleidenschaft zu ziehen.With regard to the production of a scuff-resistant furniture surface, it is an object of the invention to provide a resin-impregnated decorative paper which has a good abrasion and micro scratch resistance, without affecting the press plates.

Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung manifestieren sich in den Unteransprüchen.Advantageous embodiments of the invention manifest themselves in the subclaims.

Die Anforderungen an den Overlayfilm nach Abriebfestigkeit und Pressblechschutz einerseits und Mikrokratz- oder Scheuerbeständigkeit andererseits werden gemäß der Erfindung also dadurch gelöst,

  • dass die für die Abriebfestigkeit notwendigen relativ groben Korundpartikel auf der dem Dekor zugewandten Seite liegen und
  • die zum Erreichen der Scheuerbeständigkeit notwendigen Feinkorundpartikel auf der Oberseite der Zellstoffschicht liegen.
The requirements on the overlay film for abrasion resistance and pressure plate protection on the one hand and micro scratch or abrasion resistance on the other hand are thus achieved according to the invention,
  • that the relatively coarse corundum particles necessary for the abrasion resistance lie on the side facing the decor, and
  • the fine corundum particles necessary to achieve the abrasion resistance lie on top of the pulp layer.

Der notwendige Schutz der Pressbleche wird über die Korngröße und die Kornform des eingesetzten Feinkorundes sichergestellt. Je kleiner das Korn, desto geringer wird sein Abtrag bzw. Beschädigung am Pressblech im Falle eine Berührung mit diesem sein. Durch den Einsatz eines plättchenförmigen Korunds, welches sich durch das Auftragsverfahren und die Verpressung bevorzugt parallel zur Oberfläche ausrichtet, wird ebenfalls die Gefahr von Pressblechbeschädigungen reduziert, da die scharfkantigeren Schmalseiten der Korundplättchen nicht zum Blech orientiert sind.The necessary protection of the press plates is ensured by the grain size and the grain shape of the fine corundum used. The smaller the grain, the lower will be its removal or damage to the press plate in the event of contact with it. By using a platelet-shaped corundum, which preferably aligns parallel to the surface by the application method and the pressing, the risk of pressure plate damage is also reduced because the sharp edges of the narrow corundum plates are not oriented to the sheet.

Durch die Wahl der Korngröße und der Kornform sowie die gezielte Platzierung dieser beiden Korundsorten im Produkt- bzw. Overlayaufbau wird also die Forderung nach Scheuerbeständigkeit der obersten Laminatschicht einerseits und nach Pressblechschutz andererseits erfüllt.By choosing the grain size and grain shape and the targeted placement of these two types of corundum in the product or overlay structure so the requirement for abrasion resistance of the top laminate layer on the one hand and after pressure plate protection on the other hand is met.

Im Falle von scheuerfesten Möbeloberflächen kommen nur Feinkorunde in der oberflächennahen Schicht zum Einsatz, da hier im Gegensatz zum Fußboden eine weit geringere Belastung besteht und Grobkorunde nicht verwendet werden müssen.In the case of abrasion-resistant furniture surfaces only fine corundum in the near-surface layer are used, since in contrast to the floor, there is a much lower burden and coarse corundum not need to be used.

Vorzugsweise ist die Zellstoffschicht des Overlaypapiers mit einem Deckstrich aus Harz versehen, der die Feinkorundpartikel enthält.Preferably, the pulp layer of the overlay paper is provided with a top coat of resin containing the fine corundum particles.

Die für die Abriebfestigkeit zuständigen relativ groben Korundpartikel, die auf der dem Dekor zugewandten Seite des Overlayfilms angebracht werden, haben nach dem Stand der Technik Korngrößen von 30µm bis 125 µm.The responsible for the abrasion resistance of relatively coarse corundum particles, which are mounted on the decorative side facing the overlay film, have grain sizes of 30μm to 125 microns in the prior art.

Die für die Scheuerbeständigkeit zuständigen Feinkorundpartikel, die sich auf der Oberseite in einer oberflächennahern Schicht befinden, haben eine Korngröße von 0,5 - 50 µm, besonders bevorzugt zwischen 2 µm und 30 µm.The fine corundum particles responsible for the abrasion resistance, which are located on the upper side in a layer near the surface, have a particle size of 0.5-50 μm, more preferably between 2 μm and 30 μm.

Die besten Scheuerfestigkeiten ergeben sich, wenn die in Form eines Deckstriches eingebrachten Feinkorundpartikel mit einem Massenanteil von 0,5% - 50% im Deckstrichharz eingesetzte werden, als besonders vorteilhaft hat sich ein Anteil von 3 - 30% erwiesen (Anteile bezogen auf trockenes Harz).The best abrasion resistance results when the introduced in the form of a top coat fine corundum particles are used with a mass fraction of 0.5% - 50% in the top coat resin, a proportion of 3 - 30% has proved to be particularly advantageous (proportions based on dry resin) ,

Eine praktikable Variante der Erfindung sieht daher vor, dass das Auftragsgewicht des Deckstriches zwischen 1 g/m2 und 50 g/m2 beträgt. Um die Kosten des zusätzlichen Deckstrichharzes zu begrenzen, kann das Auftragsgewicht des Deckstrichharzes auch zwischen 5 g/m2 und 30 g/m2 betragen.A practicable variant of the invention therefore provides that the application weight of the top coat is between 1 g / m 2 and 50 g / m 2 . In order to limit the cost of the additional top coat resin, the coat weight of the top coat resin may also be between 5 g / m 2 and 30 g / m 2 .
