Abstract

A method for finishing wood-based panels, especially MDF or HDF panels, involves sealing with melamine resin and printing a pattern directly onto the sealing layer before adding a protective layer of melamine resin and hot-pressing as usual. A method for finishing sheets of wood or timber products, especially MDF or HDF sheet, involves (a) coating the top of the sheet with a sealing layer (A) of melamine resin, (b) printing a pattern onto the sealing layer, (c) coating the pattern with a protective layer (B) of melamine resin and (d) pressing the sheet at elevated temperature until layers (A) and (B) melt and bond together with the printed pattern between them. An independent claim is also included for timber sheeting, especially HDF or MDF flooring panels with a wood or tile pattern, in which the base panel is coated with a sealing layer which is then printed with a pattern and provided with protective anti-wear coating(s).

Description

Die Erfindung betrifft ein Verfahren zum Veredeln einer Holzwerkstoffplatte, insbesondere MDF- oder HDF-Platte mit einer Oberseite und einer Unterseite. Solche Platten werden beispielsweise für den Möbelbau verwendet. Aus ihnen können auch Paneele, insbesondere Fußbodenpaneele hergestellt werden.The invention relates to a method for finishing a wood-based panel, in particular MDF or HDF board with a top and a bottom. Such For example, panels are used for furniture making. Out of them also panels, especially floor panels are made.

Fußbodenpaneele mit einer Trägerplatte aus Holzwerkstoff werden üblicherweise als Laminatpaneele bezeichnet und sind seit vielen Jahren zur Substitution von Parkett im Handel. Das gewünschte Dekor (Parkett, Holzmaserung, Fliesen, usw.) wird auf eine Papierbahn aufgedruckt, die anschließend mit Harz beschichtet und auf eine Rolle aufgerollt oder als Bogenware gestapelt wird. Die so vorgefertigte Dekorbahn wird bei dem Fußbodenhersteller auf die Trägerplatte aufgelegt und verpresst. Durch das Aufdrucken des Dekors auf die Papierbahn, das spätere Versiegeln der Papierbahn mit Kunstharz und das anschließende Verbinden der Dekorschicht mit der Trägerplatte durch Druck und Temperatur verändert sich die Papierbahn in ihren Abmessungen. Der Fachmann spricht davon, dass das Papier wächst. Das Papier wächst sowohl in der Länge (Längenwachstum) als auch in der Breite (Breitenwachstum). Wenn diese Dekorplatte nun zu einzelnen Paneelen zugeschnitten werden soll, müssen das Längen- und Breitenwachstum berücksichtigt werden, weil anderenfalls eine ungleiche Dekorverteilung auf den einzelnen Paneelen vorhanden wäre. Diese hätte zur Folge, dass der aus einer ungleich verteilten Dekorschicht zusammengesetzte Fussboden an den Verbindungskanten der Paneele Dekorsprünge aufweist. Selbst wenn solche Dekorsprünge nur wenige Millimeter betragen, fallen sie bei der Betrachtung auf, was den ästhetischen Eindruck negativ beeinflusst und damit die Qualität des ausgelegten Fußbodens mindert.Floor panels with a wooden-based carrier board usually become referred to as laminate panels and have been for many years for the substitution of Parquet in the trade. The desired decor (parquet, wood grain, tiles, etc.) is printed on a paper web, which is then coated with resin and rolled up on a roll or stacked as a sheet. The so prefabricated Decorative sheet is placed at the floor manufacturer on the support plate and squeezed. By printing the decoration on the paper web, the subsequent sealing of the paper web with synthetic resin and subsequent bonding the decorative layer with the support plate changed by pressure and temperature the paper web in their dimensions. The expert speaks of that the paper is growing. The paper grows both in length (length growth) as well as in width (width growth). If this decorative plate now to individual Panels should be tailored to the length and width growth be taken into account, because otherwise an uneven decor distribution on the individual panels would be present. This would result in that from a unevenly distributed decorative layer composite floor at the joint edges the panels has Dekorsprünge. Even if such decoration jumps just a few millimeters, they stand out when looking at what the aesthetic impression negatively influenced and thus the quality of the designed Floor decreases.

Um qualitätsgerecht produzieren zu können, muss das Papierwachstum erfasst und die Säge, die die Paneele aus der Trägerplatte zurechtsägt, entsprechend eingestellt werden. Eine manuelle Einstellung ist sehr zeitaufwändig. Die DE 100 19 054 C1 beschreibt ein Verfahren zum Zuschneiden von Paneelen aus einer Trägerplatte, mit dem die Säge automatisch an das Papierwachstum angepasst werden kann. Hierzu sind Kameras notwendig, die die Ist-Lage definierter Dekorpunkte ermitteln. Die Ist-Lage wird dann mit der Soll-Lage verglichen und die Abweichung des Breiten- oder Längenmaßes ermittelt, so dass die Säge entsprechend eingestellt werden kann.In order to be able to produce quality, paper growth must be recorded and the saw, which sawn the panels from the carrier plate, accordingly be set. Manual adjustment is very time consuming. The DE 100 19 054 C1 describes a method for cutting panels from a Carrier plate with which the saw automatically adapted to the paper growth can be. For this purpose, cameras are necessary, which are the actual position of defined decor points determine. The actual position is then compared with the desired position and the Deviation of latitude or longitude determined so that the saw accordingly can be adjusted.

Um den Zuschnitt zu optimieren muss also ein hoher Aufwand betrieben werden, der die Herstellung hochwertiger Paneele verteuert. Um die Optik des Laminatpaneels der Optik eines Naturholzpaneels weiter anzupassen, kann in der Presse, in der die Dekorschicht mit der Trägerplatte verpresst wird, eine ein Relief aufweisende Matrize vorgesehen sein, die ein der Holzmaserung entsprechendes Relief in die Kunstharzschicht prägt. Da das Papierwachstum nicht reproduzierbar ist, ist es nicht möglich, das Relief vollständig in Übereinstimmung mit dem Dekor zu bringen. Die Fugen eines Fliesenspiegels können, da hier Abweichungen sofort sichtbar wären, nicht in die Oberfläche geprägt werden. In order to optimize the cutting so a lot of effort must be operated which makes the production of high-quality panels more expensive. To the look of the laminate panel The appearance of a natural wood panel can continue to adapt in the press, in the decorative layer is pressed with the carrier plate, a relief having Matrize be provided, which corresponds to the wood grain relief imprinted in the synthetic resin layer. Since paper growth is not reproducible, It is not possible to fully customize the relief in accordance with the decor bring. The joints of a tiled mirror can, as here deviations immediately would be visible, not be embossed into the surface.

Von dieser Problemstellung ausgehend soll ein Verfahren zum Veredeln einer Holzwerkstoffplatte angegeben werden, mit dem die vorstehend beschriebenen Nachteile vermieden werden.Based on this problem, a method for refining a Wood material board can be specified with those described above Disadvantages are avoided.

Die Problemlösung erfolgt mit einer gattungsgemäßen Holzfaserplatte durch folgende Schritte:

  • a) Auftragen einer Versiegelungsschicht aus Melaminharz auf die Oberseite der Platte,
  • b) Aufdrucken eines Dekors auf die Versiegelungsschicht,
  • c) Auftragen einer Schutzschicht aus Melaminharz auf das Dekor,
  • d) Verpressen der Platte unter Temperatureinwirkung, bis die Schutzschicht und die Versiegelungsschicht schmelzen und sich unter Einschluss des aufgedruckten Dekors miteinander verbinden.
    • The problem is solved with a generic wood fiber board by the following steps:
  • a) applying a sealing layer of melamine resin to the top of the plate,
  • b) imprinting a decoration on the sealing layer,
  • c) applying a protective layer of melamine resin to the decor,
  • d) pressing the plate under the effect of temperature until the protective layer and the sealing layer melt and connect to each other, including the printed decoration.

    • Dadurch, dass das Dekor auf die Platte aufgedruckt wird, fällt nicht nur die mit dem Papierwachstum verbundene Problematik fort, sondern auch das Handling, das mit dem Auflegen der Papierbahn auf die Plattenoberseite verbunden ist. Durch das Aufbringen der Versiegelungsschicht auf der Trägerplatte wird verhindert, dass die Druckfarbe von der Trägerplatte aufgesaugt wird, was ohne die Versiegelungsschicht der Fall wäre, da die Trägerplatte als solche saugfähig ist. Durch die Versiegelungsschicht wird die Dekorfarbe an der Oberfläche gehalten und gebunden, so dass die Dekorschicht an der Oberfläche bleibt und ein präzises, klar sichtbares Dekor ausbildet. Die Schutzschicht aus Melaminharz ersetzt das bekannte Overlay, das bei den bekannten Veredelungsverfahren auf das Dekorpapier aufgelegt wird. Durch das anschließende Verpressen unter Temperatureinwirkung, bis die Schutzschicht und die Versiegelungsschicht schmelzen, wird das Dekor eingeschlossen und Versiegelungsschicht und Schutzschicht werden zu einem Verbund. Mit Hilfe der Pressplatte kann der Glanzgrad der Oberfläche eingestellt werden. Wird eine polierte Pressplatte verwendet, wird eine hochglänzende Oberfläche erzielt.The fact that the decor is printed on the plate, not only falls with the paper growth, but also the handling, which is connected to the laying of the paper web on the top of the plate. By applying the sealing layer on the carrier plate is prevented that the ink is absorbed by the support plate, what without the Sealing layer would be the case, since the carrier plate as such is absorbent. The sealing layer holds the decorative paint on the surface and bound so that the decorative layer remains on the surface and a precise, clearly visible decor. The protective layer of melamine resin replaced the well-known overlay, which in the known finishing process on the decorative paper is hung up. By the subsequent pressing under the influence of temperature, until the protective layer and the sealing layer melt, the decor is included and sealing layer and protective coating become a composite. With the help of the press plate, the gloss of the Surface to be adjusted. If a polished press plate is used, achieved a high gloss finish.

    Vorzugsweise wird die Platte noch durch folgende Schritte veredelt:

  • e) Auftragen einer Versiegelungsschicht aus Melaminharz auf die Unterseite der Platte,
  • f) Aufbringen einer Farbschicht auf die Versiegelungsschicht,
  • g) Auftragen einer Schutzschicht aus Melaminharz auf die Farbschicht,
  • h) Verpressen der Platte unter Temperatureinwirkung, bis die Schutzschicht und die Versiegelungsschicht schmelzen und sich unter Einschluss der Farbschicht miteinander verbinden.
    • Preferably, the plate is refined by the following steps:
  • e) applying a sealing layer of melamine resin to the underside of the plate,
  • f) applying a color layer to the sealing layer,
  • g) applying a protective layer of melamine resin to the paint layer,
  • h) pressing the plate under the effect of temperature until the protective layer and the sealing layer melt and combine with the inclusion of the color layer.

    • Durch diese Schritte wird der sonst übliche Unterzug bei einem Laminatpaneel ersetzt. Die einzelnen Schichtdicken entsprechen denen auf der Oberseite, so dass ein Verzug der Platte ausgeschlossen wird.These steps make the usual joist in a laminate panel replaced. The individual layer thicknesses correspond to those on the upper side, see above that a distortion of the plate is excluded.

    Insbesondere vorteilhaft ist es, wenn die Oberseite und die Unterseite gleichzeitig veredelt werden, wodurch die Herstellzeit reduziert wird.It is particularly advantageous if the top and the bottom at the same time be refined, whereby the production time is reduced.

    Die Veredelung der Platte kann im Durchlauf erfolgen, wobei vorzugsweise zum Verpressen eine Durchlaufpresse verwendet wird. Hierdurch wird die Herstellzeit weiter verkürzt, was die Produktionskosten senkt.The refinement of the plate can be done in a continuous, preferably for Pressing a continuous press is used. This will change the manufacturing time further shortened, which lowers the production costs.

    Die Versiegelungsschichten und/oder die Schutzschichten werden vorzugsweise in mehreren Einzelschichten aufgetragen, wobei jede Einzelschicht vor dem Auftragen der nächsten Schicht austrocknet. Die Einzelschichten haben ein Flächengewicht von jeweils 10-40 g/m2. Die Versiegelungsschicht besteht vorzugsweise aus zwei Einzelschichten; die Schutzschicht aus vier Einzelschichten. Auch die Druckfarbe kann in mehreren Schichten aufgetragen werden.The sealing layers and / or the protective layers are preferably applied in a plurality of individual layers, wherein each individual layer dries out before the application of the next layer. The individual layers have a weight per unit area of 10-40 g / m 2 . The sealing layer preferably consists of two individual layers; the protective layer of four individual layers. The printing ink can also be applied in several layers.

    Damit das Dekor bzw. die Farbschicht beim Verpressen nicht schmilzt oder sich farblich verändert, muss eine entsprechend hitzebeständige Farbe bzw. hitzebeständiger Lack verwendet werden.So that the decor or the color layer does not melt during pressing or itself changed in color, must have a correspondingly heat-resistant color or heat-resistant Lacquer can be used.

    Um eine glatte Oberfläche zu erhalten, wird die Platte vorzugsweise geschliffen, bevor die erste Einzelschicht der Versiegelungsschicht aufgetragen wird. In mindestens eine Einzelschicht der Schutzschicht ist Korund zur Erhöhung der Abriebfestigkeit eingemischt oder eingestreut. Auch können in der Schutzschicht antibakterielle und/oder Antistatik-Additive eingemischt oder aufgestreut werden. Dies kann in derselben oder in einer anderen Einzelschicht erfolgen. Vorzugsweise sind alle Einzelschichten entsprechend behandelt. In die Versiegelungsschicht und/oder die Schutzschicht können Füllstoffe eingebracht werden. Als Füllstoff kommen Holzfasern, Holzstäube, Metalle, Mineralstoffe (Lehm, Sand), Kunststoffe, Zellulose oder Asche in Frage. Über die Füllstoffe kann eine Struktur erzielt werden, die korrespondierend zu dem Dekor aufgebracht wird, so dass filigrane Reliefs erzeugbar sind. In den Einzelschichten auf der Unterseite dienen die Füllstoffe beispielsweise zur Trittschalldämmung.In order to obtain a smooth surface, the plate is preferably ground, before the first single layer of the sealant layer is applied. In at least a single layer of the protective layer is corundum to increase the abrasion resistance mixed or sprinkled. Also can be antibacterial in the protective layer and / or antistatic additives are mixed or sprinkled. This can be done in the same or in a different single layer. Preferably All individual layers are treated accordingly. In the sealing layer and / or the protective layer fillers can be introduced. As a filler come wood fibers, wood dusts, metals, minerals (loam, sand), plastics, Cellulose or ash in question. About the fillers, a structure can be achieved be applied, which is corresponding to the decor, so that filigree Reliefs are generated. The fillers are used in the individual layers on the underside For example, for impact sound insulation.

    Die Veredelung der Oberseite der Platte kann auch nur bereichsweise erfolgen. Vorzugsweise erfolgt die Veredelung auf einer gegenüber der Oberseite schräg verlaufenden Fläche der Platte. Hierzu können mehrere V-Fugen in die Oberseite der Platte eingeprägt werden. Nach dem Veredeln wird die Platte mittig entlang der V-Fugen zersägt, so dass einzelne Paneele entstehen, deren Seitenkanten eine Fase aufweisen. Diese Fasen unterstreichen später die Optik einer Fuge zwischen einzelnen Paneelen eines Fußbodens. The refinement of the top of the plate can also be made only partially. Preferably, the finishing is carried out on a slant relative to the top extending surface of the plate. For this purpose, several V-joints in the top be embossed on the plate. After refining, the plate is centered along sawing the V-joints so that individual panels are created whose side edges have a chamfer. These chamfers later emphasize the look of a fugue between individual panels of a floor.

    Da keine Papierschichten verwendet werden, sind die Platten vor Verzug, der durch die Eigenzugkraft der Papiere entstehen könnte, sicher. Aufgrund der dünnen Schichten können kurze Prozesszeiten realisiert werden. Die in die Einzelschichten auf der Unterseite der Platte eingebrachten Füllstoffe können zur Trittschaldämmung vorgesehen werden.Since no paper layers are used, the plates are warping, the could be caused by the intrinsic power of the papers, certainly. Because of the thin Layers short process times can be realized. The in the individual layers Fillers placed on the underside of the plate can be used for sound insulation be provided.

    Anstatt eine Trägerplatte aus HDF oder MDF zu veredeln, können auch OSB-Platten oder herkömmliche Spanplatten mit einer entsprechend fein gestreuten Deckschicht Verwendung finden. Auch ist es denkbar, die Versiegelungsschicht so dick auszubilden, dass Unebenheiten in der Platte (OSB) ausgeglichen werden.Instead of finishing a carrier plate made of HDF or MDF, OSB boards can also be used or conventional chipboard with a correspondingly finely divided Cover layer find use. It is also conceivable, the sealing layer form so thick that unevenness in the plate (OSB) are compensated.

    Die Platten können nicht nur als Fußbodenpaneele Verwendung finden, sondern sie können auch im Möbelbau eingesetzt werden.The panels can not only be used as floor panels, but They can also be used in furniture construction.

    Teile des erfindungsgemäßen Verfahrens sind dazu geeignet, einer Platte mit Echtholzoberfläche (Holzwerkstoffträgerplatte mit Furnierschicht, Massivholz) Laminateigenschaften, nämlich hohe Abriebfestigkeit, hohe Stoßfestigkeit und einstellbarer Glanzgrad zu verleihen. Hierzu kann auf das Aufbringen der Dekorschicht auf der Oberseite bzw. der Farbschicht auf der Unterseite verzichtet werden. Das spätere Versiegeln des verlegten Parketts kann damit entfallen. Durch Aufdrucken einer entsprechenden Dekorschicht können preiswerte Hölzer aufgewertet werden. So kann beipielsweise auf ein Kiefernfurnier ein Eichendekor aufgedruckt und entsprechend farblich hervorgehoben werden.Parts of the method according to the invention are suitable to a plate with Real wood surface (wooden base plate with veneer layer, solid wood) Laminate properties, namely high abrasion resistance, high impact resistance and to give adjustable degree of gloss. For this purpose, the application of the decorative layer omitted on the top or the color layer on the bottom become. The subsequent sealing of the laid parquet can thus be omitted. By printing a corresponding decorative layer inexpensive woods can be upgraded. For example, an oak decoration may be applied to a pine veneer printed and highlighted in accordance with color.

    Die Pressplatte kann mit einem zum Dekor korrespondierenden Relief versehen sein. Beim Verpressen der Platte werden dann Vertiefungen in der Schutzschicht erzeugt, die beispielsweise zu einer Holzmaserung oder zu einem Fliesenspiegel korrespondieren. Damit wird die Haptik der Oberfläche an einer natürliche Oberfläche angepasst. The press plate can be provided with a relief corresponding to the decor be. When pressing the plate then depressions in the protective layer produced, for example, to a wood grain or to a tile mirror correspond. This changes the feel of the surface to a natural surface customized.

    Insbesondere können in die Schutzschicht in Längsrichtung und/oder Querrichtung der Platte verlaufende V-Fugen eingeprägt werden. Bei der weiteren Verarbeitung werden dann Paneele aus der Platte ausgesägt, indem mittig entlang der V-Fuge gesägt wird. Dadurch erhalten die Paneele dann eine gefasste Kante.In particular, in the protective layer in the longitudinal direction and / or transverse direction the plate running V-joints are stamped. For further processing then panels are sawn out of the plate by centered along the V-joint is sawn. As a result, the panels are given a bordered edge.
