Description

  • Die Erfindung betrifft ein Verfahren zum Veredeln einer Holzwerkstoffplatte, insbesondere MDF-oder HDF-Platte mit einer Oberseite und einer Unterseite. The invention relates to a method for finishing a wood material board, in particular MDF or HDF board having a top and a bottom. Solche Platten werden beispielsweise für den Möbelbau verwendet. Such panels are used for example for furniture making. Aus ihnen können auch Paneele, insbesondere Fußbodenpaneele hergestellt werden. From them can also panels, especially floor panels are manufactured.
  • Fußbodenpaneele mit einer Trägerplatte aus Holzwerkstoff werden üblicherweise als Laminatpaneele bezeichnet und sind seit vielen Jahren zur Substitution von Parkett im Handel. Floor panels with a carrier plate of wood material commonly referred to as laminate panels and the substitution of parquet in the trade for many years. Das gewünschte Dekor (Parkett, Holzmaserung, Fliesen) wird auf eine Papierbahn aufgedruckt, die anschließend mit Harz beschichtet und auf eine Rolle aufgerollt oder als Bogenware gestapelt wird. The desired decor (parquet, wood grain, tiles) is printed on a paper web, which is then coated with resin and wound onto a roll or stacked in sheets. Die so vorgefertigte Dekorbahn wird bei dem Fußbodenhersteller auf die Trägerplatte aufgelegt und verpresst. The so pre-made decorative sheet is placed on the floor manufacturer to the carrier plate and pressed. 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. By printing the decoration onto the paper web, the subsequent sealing of the paper web with synthetic resin and the subsequent joining of the decorative layer to the carrier plate by pressure and temperature, the paper web is changed in its dimensions. Der Fachmann spricht davon, dass das Papier wächst. The expert says that the paper is growing. Das Papier wächst sowohl in der Länge (Längenwachstum) als auch in der Breite (Breitenwachstum). The paper grows both in length (length growth) and in width (width growth). 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. If this decorative panel is now to be cut into individual panels, the length and width growth must be taken into account because otherwise an unequal distribution decor would be present on the individual panels. Diese hätte zur Folge, dass der aus einer ungleich verteilten Dekorschicht zusammengesetzte Fußboden an den Verbindungskanten der Paneele Dekorsprünge aufweist. This would have the consequence that the composite from an unevenly distributed decorative layer floor at the connecting edges of the panels having decorative jumps. Selbst wenn solche Dekorsprünge nurwenige Millimeter betragen, fallen sie bei der Betrachtung auf, was den ästhetischen Eindruck negativ beeinflusst und damit die Qualität des ausgelegten Fußbodens mindert. Even if such jumps decor amount nurwenige millimeters, they fall on when considering what negatively affected the aesthetic impression and therefore reduces the quality of the laid floor.
  • Um qualitätsgerecht produzieren zu können, muss das Papierwachstum erfasst und die Säge, die die Paneele aus derträgerplatte zurechtsägt, entsprechend eingestellt werden. In order to produce the required quality, the paper growth must be detected and can be adjusted according to the saw, the handle saws the panels from derträgerplatte. Eine manuelle Einstellung ist sehr zeitaufwändig. A manual adjustment is very time consuming. Die The DE 100 19 054 C1 DE 100 19 054 C1 beschreibt ein Verfahren zum Zuschneiden von Paneelen aus einer Trägerplatte, mit dem die Säge automatisch an das Papierwachstum angepasstwerden kann. describes a method for cutting panels of a carrier plate with which the saw can automatically be adapted to the paper growth. Hierzu sind Kameras notwendig, die die Ist-Lage definierter Dekorpunkte ermitteln. To this end cameras are necessary to determine the actual position of defined decorative points. 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. The actual position is then compared with the desired position and determines the deviation of the width or length dimension, so that the saw can be adjusted accordingly.
  • Um den Zuschnitt zu optimieren muss also ein hoher Aufwand betrieben werden, der die Herstellung hochwertiger Paneele verteuert. To optimize the cutting so a high effort has to be, the more expensive the manufacture of high quality panels. 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. To further customize the appearance of the laminate panel of the optics of Naturholzpaneels, a relief having the die may be provided in the press, in which the decorative layer is pressed together with the support plate, that characterizes a wood grain corresponding relief in the synthetic resin layer. Da das Papierwachstum nicht reproduzierbar ist, ist es nicht möglich, das Relief vollständig in Übereinstimmung mit dem Dekor zu bringen. Since the paper growth is not reproducible, it is not possible to bring the relief in full compliance with the decor. Die Fugen eines Fliesenspiegels können, da hier Abweichungen sofort sichtbar wären, nicht in die Oberfläche geprägt werden. The joints of a mirror tiles, since deviations would be immediately visible here, not be embossed into the surface.
  • In der In the DE 195 32 819 A1 DE 195 32 819 A1 wird ein Verfahren zur Herstellung einer Holzwerkstoffplatte mit einer optisch gestaltbaren Oberfläche offenbart, bei der auf der Holzwerkstoffplatte nacheinander eine Grundierfärbung, eine Versiegelung, eine Druckbasis und ein Dekordruck aufgebracht werden. is a process for the production of a wood material board with an optically tailored surface disclosed to be in the applied to the wood material board in succession, a Grundierfärbung, a seal, a printing base, and a decorative print. Die Druckbasis wird dabei aus einer Grundiereinfärbung bzw. einer Grundierung einer Lackverslegelung und einem Oberflächenlack aufgebaut. The pressure base is constructed from a Grundiereinfärbung or a primer and a surface paint a Lackverslegelung. Mittels Gravurzylindern kann auf die Druckbasis ein Dekordruck beispielsweise in einem Zweifarbendruck aufgedruckt werden. By means of gravure cylinders can be printed on the print base, a decorative printing for example in a two-color printing. Auf diesen Druck kann abschließend ein mehrschichtiger Acrylat-UV-Lack aufgebracht werden, der mittels UV-Licht härtbar ist. At this pressure, a multilayer acrylate UV coating can be finally applied, which is curable by UV light.
  • In der In the DE 199 41 300 A1 DE 199 41 300 A1 wird eine heiß verformbare Pressstoff-Platte mit einem Kern aus Holz und/ oder Cellulose-Fasem beschrieben, die mit einem hitzehärtbaren Formaldehydharz imprägniert ist. a deformable hot press fabric panel having a core of wood and / or cellulose fibers is described which is impregnated with a thermosetting formaldehyde resin. Auf diese Pressstoff-Platte können beidseitig eine Dekorationsschicht aus einer Kunststoff-, Papier- oder Holzfolie und/ oder eine Lackschicht aufgebracht sein. In this press fabric panel a decorative layer made of a plastic, paper or wood sheet and / or a lacquer layer may be applied on both sides. Weiterhin können die Dekorationsschichten auch aus einem vernetzten Acryl-, Urethan-, Epoxid- oder Melaminharz bestehen, die einen Füllstoff oder einen Farbstoff enthalten. Further, the decorative layers can also consist of a crosslinked acrylic, urethane, epoxy or melamine resin, containing a filler or a colorant.
  • Die The EP 1 026 008 A2 EP 1026008 A2 offenbart ein Overlay, ein Verfahren zur Herstellung eines Overlays und ein Verfahren zur Herstellung mehrschichtigen Laminates, bei dem auf eine Trägerschicht unterseitig Muster und farbgebende Schichten im Konterdruckaufgebrachtwerden. discloses an overlay, a method for producing an overlay and a process for producing multi-layer laminate, in which a carrier layer with each other patterns and coloring layers in the counter pressure be applied. Als Trägerschicht kann hierbei ein mit Melaminharz imprägniertes Papier eingesetzt werden, das mit dem Laminat verpresst wird. As a carrier layer impregnated with melamine resin paper can be used here, which is compressed with the laminate.
  • Die The DE 197 51 115 A1 DE 197 51 115 A1 offenbart ein Verfahren zur Beschichtung beispielsweise eines Paneels, bei dem auf die Oberfläche zumindest eine Farbschicht mittels eines Druckverfahrens, insbesondere mittels Siebdruck, aufgebracht wird. discloses a method for coating, for example a panel, in which on the surface of at least one color layer is applied by a printing process, especially by screen printing. Dabei kann die Oberfläche unbehandelt, geschliffen oder vorbehandelt, insbesondere lakkiert, sein. The surface can be untreated, sanded or pretreated, in particular lakkiert. Abschließend kann die aufgebrachte Farbschicht durch eine Beschichtung mit Klarlack abgedeckt sein. Finally, the applied ink layer may be covered by a coating of clear lacquer.
  • Von dieser Problemstellung ausgehend soll ein Verfahren zum Veredeln einer Holzwerkstoffplatte angegeben werden, mit dem die vorstehend beschriebenen Nachteile vermieden werden. Starting from this problem, a process for finishing a wood material board is to be provided, with which the disadvantages described above are avoided.
  • Die Problemlösung erfolgt mit einer gattungsgemäßen Holzfaserplatte durch folgende Schritte. The problem solution is carried out with a generic fiberboard by the steps.
  1. a) Auftragen einer Versiegelungsschicht aus Melaminharz auf die Oberseite der Platte, a) applying a sealing layer made of melamine resin on the upper surface of the plate,
  2. b) Aufdrucken eines Dekors, das hitzebeständige Farben aufweist, vorzugsweise aus hitzebeständigen Farben besteht, auf die Versiegelungsschicht, b) printing a decoration, which has heat-resistant paints, and preferably consists of heat-resistant paints, onto the sealing layer,
  3. c) Auftragen einer Schutzschicht aus Melaminharz auf das Dekor, c) applying a protective layer made of melamine resin to the decoration,
  4. d) Verpressen der Platte unter Temperatureinwirkung, bis die Schutzschicht und die Versiegelungsschicht schmelzen und sich unter Einschluss des aufgedruckten Dekors miteinander verbinden. d) pressing the plate under the effect of temperature until the protective layer and the sealing layer melt and bond to one another with inclusion of the printed decor.
  • 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. Characterized in that the decoration is printed on the plate, not only the problems associated with the paper growth is continued, but also the handling, which is connected to the laying of the web on the plate upper side. 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. By the application of the sealing layer on the support plate that the ink is absorbed by the carrier plate, which would be the case without the sealing layer, since the carrier plate as such is absorbent is prevented. 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. By sealing layer, the decorative ink is held on the surface and bound so that the decorative layer remains on the surface and forming a precise, clearly visible pattern. Die Schutzschicht aus Melaminharz ersetzt das bekannte Overlay, das bei den bekannten Veredelungsverfahren auf das Dekorpapier aufgelegt wird. The protective layer of melamine resin replaces the known overlay that is placed in the known finishing processes on the decorative paper. 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. melt by the subsequent pressing under the effect of temperature until the protective layer and the sealing layer, the decor is enclosed and sealing layer and protective layer to form a composite. Mit Hilie der Pressplatte kann der Glanzgrad der Oberfläche eingestellt werden. With Hilie the press plate of the gloss of the surface can be adjusted. Wird eine polierte Pressplatte verwendet, wird eine hochglänzende Oberfläche erzielt. If a polished press plate is used, a high gloss surface is achieved.
  • 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 the decor or the color layer does not melt or during pressing changes color, a suitably heat-resistant paint or heat-resistant paint must be used.
  • Vorzugsweise wird die Platte noch durch folgende Schritte veredelt: Preferably, the plate will be refined by the steps of:
    • e) Auftragen einer Versiegelungsschicht aus Melaminharz auf die Unterseite der Platte, e) applying a sealing layer made of melamine resin on the underside of the plate,
    • f) Aufbringen einer Farbschicht auf die Versiegelu ngsschicht, f) applying a color layer onto the Versiegelu ngsschicht,
    • g) Auftragen einer Schutzschicht aus Melaminharz auf die Farbschicht, g) applying a protective layer made of melamine resin to the paint layer,
    • h) Verpressen der Platte unter Temperatureinwirkung, bis die Schutzschicht und die Versiegelungsschicht schmelzen und sich unter Einschluss der Farbschicht miteinander verbinden. h) compressing the plate under the effect of temperature until the protective layer and the sealing layer melt and bond to one another, including the color layer.
  • Durch diese Schritte wird der sonst übliche Unterzug bei einem Laminatpaneel ersetzt. Through these steps, the usual joist is replaced with a laminate panel. Die einzelnen Schichtdicken entsprechen denen auf der Oberseite, so dass ein Verzug der Platte ausgeschlossen wird. The individual layer thicknesses corresponding to those on the top, so 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 when the top and bottom whereby the manufacturing time is reduced are refined at the same time, is.
  • Die Veredelung der Platte kann im Durchlauf erfolgen, wobei vorzugsweise zum Verpressen eine Durchlaufpresse verwendetwird. The finishing of the panel can be carried out in a continuous, preferably used for crimping a continuous press. Hierdurch wird die Herstellzeit weiter verkürzt, was die Produktionskosten senkt. In this way, the manufacturing time is further reduced, thereby reducing production costs.
  • Die Versiegelungsschichten und/oder die Schutzschichten werden vorzugsweise in mehreren Einzelschichten aufgetragen, wobei jede Einzelschicht vor dem Auftragen der nächsten Schicht austrocknet. The sealing layers and / or protective layers are preferably applied in a plurality of individual layers, each individual layer from drying before applying the next layer. Die Einzelschichten haben ein Flächengewicht von jeweils 10-40 g/m 2 . The individual layers have an area weight of in each case 10-40 g / m 2. Die Versiegelungsschicht besteht vorzugsweise aus zwei Einzelschichten; The sealing layer preferably consists of two individual layers; die Schutzschicht aus vier Einzelschichten. the protective layer of four individual layers. Auch die Druckfarbe kann in mehreren Schichten aufgetragen werden. Also, the ink can be applied in several layers.
  • Um eine glatte Oberfläche zu erhalten, wird die Platte vorzugsweise geschliffen, bevor die erste Einzelschicht der Versiegelungsschicht aufgetragen wird. In order to obtain a smooth surface, the plate is preferably polished before the first single layer of the sealing layer is applied. In mindestens eine Einzelschicht der Schutzschicht ist Korund zur Erhöhung der Abriebfestigkeit eingemischt oder eingestreut. In at least a single layer of the protective layer corundum is mixed or to increase the abrasion resistance interspersed. Auch können in der Schutzschicht antibakterielle und/oder Antistatik-Additive eingemischt oder aufgestreut werden. Antibacterial and / or anti-static additives can be blended or sprinkled in the protective layer. Dies kann in derselben oder in einer anderen Einzelschicht erfolgen. This can be done in the same or a different single layer. Vorzugsweise sind alle Einzelschichten entsprechend behandelt. Preferably, all of the individual layers are treated accordingly. In die Versiegelungsschicht und/oder die Schutzschicht können Füllstoffe eingebracht werden. Fillers can be incorporated into the sealing layer and / or the protective layer. Als Füllstoff kommen Holzfasern, Holzstäube, Metalle, Mineralstoffe (Lehm, Sand), Kunststoffe, Zellulose oder Asche in Frage. As filler are wood fibers, wood dust, metals, minerals (clay, sand), plastics, cellulose or ash in question. Überdie Füllstoffe kann eine Struktur erzielt werden, die korrespondierend zu dem Dekor aufgebracht wird, so das filigrane Reliefs erzeugbar sind. Via the fillers can be achieved a structure which is correspondingly applied to the decor, the filigree reliefs are generated. In den Einzelschichten auf der Unterseite dienen die Füllstoffe beispielsweise zur Trittschalldämmung. In the individual layers on the bottom of the fillers are used for example for sound reduction.
  • Die Veredelung der Oberseite der Platte kann auch nur bereichsweise erfolgen. The finishing top of the plate can also be done only in certain areas. Vorzugsweise erfolgt die Veredelung auf einer gegenüber der Oberseite schräg verlaufenden Fläche der Platte. Preferably, the processing is done on a top side opposite the inclined surface of the plate. Hierzu können mehrere V-Fugen in die Oberseite der Platte eingeprägt werden. To this end, a number of V-grooves can be embossed in the top of the plate. Nach dem Veredeln wird die Platte mittig entlang der V-Fugen zersägt, so dass einzelne Paneele entstehen, deren Seitenkanten eine Fase aufweisen. After finishing the plate is centrally sawed along the V-grooves, so that individual panels are created whose side edges have a chamfer. Diese Fasen unterstreichen später die Optik einer Fuge zwischen einzelnen Paneelen eines Fußbodens. These chamfers underline the look of a joint between individual panels of a floor later.
  • Da keine Papierschichten verwendet werden, sind die Platten vor Verzug, der durch die Eigenzugkraft der Papiere entstehen könnte, sicher. Since no paper layers are used, the plates before delay that might be caused by the inherent tension of the papers, of course. Aufgrund der dünnen Schichten können kurze Prozesszeiten realisiert werden. Because of the thin layers short processing times can be realized. Die in die Einzelschichten auf der Unterseite der Platte eingebrachten Füllstoffe können zur Trittschalldämmung vorgesehen werden. The introduced into the individual layers on the underside of the plate fillers may be provided for impact sound insulation.
  • Anstatt eine Trägerplatte aus HDF oder MDF zu veredeln, können auch OSB-Platten oder herkömmliche Spanplatten mit einer entsprechend fein gestreuten Deckschicht Verwendung finden. to refine instead of a support plate made of HDF or MDF, and OSB boards or conventional particle board can be used with a correspondingly finely dispersed surface layer. Auch ist es denkbar, die Versiegelungsschicht so dick auszubilden, dass Unebenheiten in der Platte (OSB) ausgeglichen werden. it is also conceivable to form the sealing layer so thick that unevenness in the board (OSB) are compensated.
  • Die Platten können nicht nur als Fußbodenpaneeie Verwendung finden, sondern sie können auch im Möbelbau eingesetzt werden. The plates can be found not only as Fußbodenpaneeie use, but they can also be used in furniture making.
  • Bei einer Holzwerkstoffplatte, insbesondere einem Fußbodenpaneel, bestehend aus einer HDF- oder MDF-Trägerplatte, mit einer Oberseite und einer Unterseite, wobei die Oberseite ein Dekor, vorzugsweise ein Holz- oder Fliesendekor aufweist, wobei auf der Trägerplatte eine Verslegelungsschicht aufgebracht ist, auf die ein Dekor, das hitzebeständige Farben aufweist, vorzugsweise aus hitzebeständigen Farben besteht, aufgedruckt ist und wobei das Dekor mit zumindest einer Schutzschicht abgedeckt ist, besteht die Versiegelungsschicht aus Melaminharz. In a wood material board, in particular a floor panel, consisting of an HDF or MDF support with a top and a bottom, wherein the upper surface preferably comprises a decor, a wood or tile decoration, wherein on the carrier plate a Verslegelungsschicht is applied to the a decoration, which has heat-resistant paints, and preferably consists of heat-resistant inks is printed, and wherein the decor with at least one protective layer is covered, there is a sealing layer made of melamine resin.
  • Durch Aufdrucken einer entsprechenden Dekorschicht können preiswerte Hölzer aufgewertet werden. By printing a corresponding decorative layer inexpensive wood can be upgraded. So kann beispielsweise auf ein Kiefernfurnier ein Eichendekoraufgedruckt und entsprechend farblich hervorgehoben werden. For example, on a pine veneer an oak decor Printed and are highlighted in the appropriate color.
  • Die Pressplatte kann mit einem zum Dekor korrespondierenden Relief versehen sein. The press plate may be provided with a corresponding to the decorative relief. Beim Verpressen der Platte werden dann Vertiefungen in der Schutzschicht erzeugt, die beispielsweise zu einer Holzmaserung oderzu einem Fliesenspiegel korrespondieren. During pressing of the plate wells are then generated in the protective layer, for example, correspond to a wood grain oderzu a tiling pattern. Damit wird die Haptik der Oberfläche an eine natürliche Oberfläche angepasst. So the feel of the surface is adapted to a natural surface.
  • Vorteilhafterweise ist das Dekor unmittelbar auf der Versiegelungsschicht aufgedruckt. Advantageously, the decor is printed directly onto the sealing layer. Zur Erhöhung der Abriebfestigkeit können auf dem Dekor Strukturmittel oder Korundkörner aufgebracht sein. To increase the abrasion resistance structure means or corundum grains can be applied to the decor.
  • Die Trägerplatte kann auf der Ober- und/oder Unterseite geglättet, vorteilhafter Weise geschliffen sein. The carrier plate can be smoothed on the top and / or bottom, advantageously be ground.
  • Insbesondere können in die Schutzschicht in Längsrichtung und/oder Querrichtung der Platte verlaufende V-Fugen eingeprägt werden. In particular, extending V-groove can be impressed into the protective layer in the longitudinal direction and / or transverse direction of the plate. Bei derweiteren Verarbeitung werden dann Paneele aus der Platte ausgesägt, indem mittig entlang der V-Fuge gesägt wird. In said further processing panels are then cut out from the plate by centrally sawed along the V-groove. Dadurch erhalten die Paneele dann eine gefaste Kante. Thus, the panels will receive a bevelled edge.
