Another polyurethane layer (4) is applied on the lower side, where the polyurethane layer (4) contains heavier particles opposite to the polyurethane. A third polyurethane layer (6) is applied on the decorative layer, where the polyurethane layer (6) seals the decorative layer. An independent claim is also included for a method for producing a building slab.

Description

  • Bauplatte, insbesondere Fußbodenpaneel aus Holzwerkstoff, Kunststoff oder einem Gemisch aus Holzwerkstoff und Kunststoff, mit einer Oberseite und einer Unterseite und Seitenkanten, bei der zumindest auf die Oberseite eine Polyurethanschicht aufgebracht ist. Building board, in particular floor panel made from wood material, plastic or a mixture of wooden material and plastic material, having a top and a bottom and side edges, wherein at least on the upper side of a polyurethane layer is applied.
  • Solche Bauplatten werden beispielsweise als Fußbodenpaneele verwendet. Such building boards are used for example as floor panels. Bekannte Fußbodenpaneele beruhen größtenteils auf Holzwerkstoffgrundkörpern aus HDF, MDF oder OSB. Known floor panels are largely based on wood material bases of HDF, MDF or OSB. Solche Paneele weisen Nachteile auf, denn Holzwerkstoffe besitzen hygroskopische Eigenschaften, wodurch sich durch Quellen und Schwinden Größenveränderungen in den Holzwerkstoffen ergeben, die dazu führen, dass solche Bodenpaneele in Feuchträumen nicht einsetzbar sind. Such panels have disadvantages, because wood materials have hygroscopic properties, which result from swelling and shrinking size changes in the timber products which cause such floor panels can not be used in damp rooms.
  • Fußbodenpaneele sind zudem häufig mit harten, verschleißfesten Oberflächen versehen, die beim Gehen störende Geräusche erzeugen und dem natürlichen Effekt, die Laminatfußböden erzeugen sollen, entgegenwirken. Floor panels are also often provided with hard, wear resistant surfaces that generate annoying noise when walking and the natural effect that will produce laminate flooring counteract.
  • Bekannt sind auch Bodenpaneele, deren Basismaterial bereits aus wasserfestem Material, beispielsweise Kunststoff besteht. Also known are floor panels the basic material is already made of waterproof material, for example plastic. Solche Kunststoffmaterialien lassen sich jedoch nicht mit harzimprägnierten Dekor- und Overlaypapieren unter erhöhtem Druck und unter erhöhter Temperatur verpressen. However, such plastic materials do not can be pressed with resin impregnated decorative and overlay papers under increased pressure and elevated temperature.
  • Bekannt sind Laminate, auf deren plattenförmiger Basis mindestens eine dekortragende Papierlage aufgebracht ist. known laminates, at least one decor paper bearing location is applied to the plate-shaped base. Das Dekor imitiert dabei in Optik und Haptik einen natürlichen Werkstoff, wie beispielsweise Holz oder Stein. The decor imitates in look and feel a natural material such as wood or stone. Dazu kann das Dekor auch eine Prägestruktur aufweisen. For this, the decor may also have an embossed structure. Nachteilig ist die kostenintensive Herstellung durch die Verwendung dekorierter und imprägnierter Papierlagen sowie deren genaue Ausrichtung auf der plattenförmigen Basis und deren genaue Ausrichtung bezüglich eines die Prägestruktur einbringenden Werkzeugs. A disadvantage is the cost-intensive production of decorated by the use and impregnated paper layers as well as their exact alignment with the plate-shaped base and their precise alignment with respect to an embossed structure the transferring tool. Die Steuerung der Druck- und Temperaturverhältnisse einerseits und die Steuerung der Prozessgeschwindigkeit andererseits sind ebenfalls kostenintensiv. The control of the pressure and temperature conditions on the one hand and control of the process speed on the other hand are also costly.
  • Das imitierte Dekor wird auf eine Papierbahn aufgedruckt, die anschließend mit Kunstharz beschichtet und auf eine Rolle aufgerollt wird. The impersonated decor is printed on a paper web, which is then coated with resin and wound onto a roll. Die so vorgefertigte Dekorbahn wird anschließend bei dem Paneelhersteller auf Holzfaserplatten aufgebracht. The thus prefabricated decor sheet is then applied to wood fiber boards in the panel manufacturer. Durch das Aufdrucken des Dekors auf die Papierbahn, das spätere Versiegeln der Papierbahn mit Kunstharz und das anschließende durch Druck- und Temperatureinwirkung Verbinden der Dekorschicht mit der Holzwerkstoffplatte, 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 then by pressure and temperature joining of the decorative layer with the wood material board, 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, muss 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. Dies 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 nur wenige 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 decor jumps are only a few 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 entsprechend eingestellt werden, was weiterhin die Herstellung der Paneele verteuert. In order to produce the required quality, the paper growth must be detected and the saw are adjusted accordingly, which further increases the cost of manufacture of the panels.
  • Von dieser Problemstellung ausgehend, sollen Bauplatten bereitgestellt werden, die natürliche Werkstoffe nahezu perfekt imitieren und zusätzlich in Feuchträumen einsetzbar sind. Starting from this problem, panels are to be provided to mimic the natural materials almost perfectly, and in addition can be used in wet rooms. Weiterhin sollen die Eigenschaften bezüglich der Geräuschbildung beim Begehen verbessert werden. Furthermore, the properties with respect to the noise to be improved when walking. Darüber hinaus soll ein vereinfachtes und kostengünstiges Verfahren zur Herstellung der Bauplatten bereitgestellt werden. In addition, a simplified and inexpensive process for the production of the building boards to be provided.
  • Zur Problemlösung zeichnet sich die gattungsgemäße Bauplatte dadurch aus, dass auf die Polyurethanschicht eine einen natürlichen Werkstoff imitierende Dekorschicht aufgebracht ist. To solve the problem the generic building panel is characterized in that a natural material imitating the decorative layer is applied to the polyurethane layer.
  • Das Verfahren zur Herstellung einer Bauplatte zeichnet sich dadurch aus, dass auf die Polyurethanschicht eine einen natürlichen Werkstoff imitierende Dekorschicht aufgebracht wird. The method for manufacturing a building panel is characterized in that a natural material imitating the decorative layer is applied to the polyurethane layer.
  • Die Bauplatte kann sowohl auf der Unter- als auch auf der Oberseite eine erste Polyurethanschicht tragen. The building board can wear both on the bottom and on the top of a first polyurethane layer. Vorteilhafterweise dient die unterseitige Polyurethanschicht dabei als so genannter Gegenzug zur Vermeidung einer Schüsselung der Bauplatte, Zudem kann die unterseitige Polyurethanschicht, da sie elastisch ist, auch als schalldämmende Schicht Verwendung finden. Advantageously, the underside polyurethane layer serves as a so-called return to avoid curling of the building, In addition, the underside polyurethane layer since it is elastic, as a sound-insulating layer can be used.
  • Um die schalldämmenden Eigenschaften der Polyurethanschicht weiter zu verbessern, kann die unterseitige Polyurethanschicht Beimengungen gegenüber dem Polyurethan schwererer Partikel wie Sande, Mehle oder Stäube von Quarz, Granit oder Marmor oder Metallteilchen enthalten. In order to improve the sound insulating properties of the polyurethane layer on, the underside polyurethane layer may contain impurities compared to the polyurethane heavier particles such as sands, flours or particulates of quartz, granite or marble or metal particles.
  • Es ist auch möglich, dass die unterseitige Polyurethanschicht Farbpartikel enthält, um unterschiedlichen Ansprüchen an die optische Gestaltung der Bauplatte gerecht zu werden. It is also possible that the underside polyurethane layer contains colored particles to be different demands on the optical design of the building board. Durch die elastische, oberseitige Polyurethanschicht kann vortellhafterweise die Geräuschbildung beim Begehen der Bauplatte reduziert werden. The elastic, polyurethane top-side layer, the noise can be reduced vortellhafterweise in committing the building board. Zudem versiegelt die oberseitige Polyurethanschicht die Bauplatte vor dem Eindringen von Feuchtigkeit, so dass sie auch in Feuchträumen eingesetzt werden kann. In addition, the upper-side polyurethane layer seals the building board from the ingress of moisture, so that they can also be used in wet rooms.
  • Darüber hinaus dient die oberseitige Polyurethanschicht als Grundierung und/oder als Haftvermittler für eine nachfolgende, sich aus einer oder mehreren Einzelschichten zusammensetzende, Dekorschicht. In addition, the upper-side polyurethane layer serves as a primer and / or as an adhesion promoter for a subsequent, is composing of one or several individual layers, decorative layer. Hierdurch ist das Aufbringen eines mit Harz imprägnierten Dekorpapiers nicht mehr notwendig, so dass sich hier erhebliche Kosteneinsparpotentiale für die Herstellung von Bauplatten ergeben. In this way, the application of a resin-impregnated decorative paper is no longer necessary, so that there are substantial cost savings for the production of building panels here.
  • Je nach dem wie dick die Dekorschicht auf die Polyurethanschicht aufgetragen werden soll, kann die Dekorschicht aus einer oder mehreren Einzelschichten bestehen, um auch aufwändige Dekore realisieren zu können. Depending on how thick the decorative layer is to be applied to the polyurethane layer, the decorative layer can consist of one or several individual layers, in order to realize even complex designs.
  • Auf die Dekorschicht wird vorzugsweise eine abschließende Polyurethanschicht aufgetragen, um die Dekorschicht beispielsweise vor mechanischen Einwirkungen durch Begehen sowie vor Beschädigungen durch Feuchteeinwirkung zu schützen. a final polyurethane layer is preferably applied in order to protect the decorative layer for example, from mechanical impact by committing and from damage due to exposure to moisture on the decorative layer. Damit die Bauplatte einen natürlichen Werkstoff besonders genau imitieren kann, kann die obere Polyurethanschicht eine Strukturprägung aufweisen, die beispielsweise auf ein zu imitierendes Holzdekor der Dekorschicht abgestimmt ist. Thus, the building board can mimic a natural material particularly precise, the top polyurethane layer may have a structure embossing, which is tuned for example to a imitating wood decoration of the decorative layer.
  • Vorteilhafterweise beträgt die Auftragsmenge der abschließenden Polyurethanschicht für schwache Prägungen zwischen 50 und 100 g/m 2 und für starke Prägungen zwischen 100 und 400 g/m 2 . Advantageously, the coating weight of the final polyurethane layer for weak embossments between 50 and 100 g / m 2 and for strong embossed between 100 and 400 g / m 2.
  • Um die Abriebfestigkeit der abschließenden Polyurethanschicht weiter zu verbessern, können der abschließenden Polyurethanschicht als verschleißhemmende Partikel Korund beigegeben werden. To improve the wear resistance of the final polyurethane layer on, the final polyurethane layer can be added as an anti-wear particles corundum.
  • Die abschließende Polyurethanschicht kann als effekterzeugende Partikel wie Metalle oder Farbpigmente enthalten, um verschiedensten Ansprüchen an die optische Gestaltung gerecht werden zu können. The final polyurethane layer may contain, as effect-producing particles such as metals or color pigments to be a variety of requirements on the optical design to. So kann die oberste Polyurethanschicht zum Beispiel auch einfarbig sein. So the top polyurethane layer can for example be a solid color.
  • Optional oder in Kombination mit den zuvor genannten Varianten kann die abschließende Polyurethanschicht optisch aufhellende oder auch antistatisch wirkende Beimengungen enthalten, Es ist auch denkbar, der Polyurethanschicht antibakteriell wirkende und/oder schmutzabweisende Beimengungen zuzugeben, um aus den Bauplatten beispielsweise Fußböden für spezielle Anwendungsgebiete mit erhöhten Anforderungen an Hygiene herstellen zu können. Optionally, or in combination with the aforementioned variants, the final polyurethane layer may contain optical brightening or antistatic additives, it is also possible to add an antibacterial action and / or soil-repellent admixtures of the polyurethane layer to get out of the building boards, for example, floors for special applications with higher demands to manufacture of hygiene. Vorteilhafterweise kann durch die Variation der Zusammensetzung der Polyurethanschicht der Glanzgrad der Oberfläche eingestellt werden, um auch den unterschiedlichen optischen Anforderungen der verschiedenen Einsatzgebiete gerecht zu werden. Advantageously, the gloss of the surface can be adjusted by varying the composition of the polyurethane layer to satisfy the most different optical requirements of different applications.
  • Alternativ können sowohl die Unter- als auch die Oberseite der Bauplatte einen gleichen Schichtaufbau erhalten. Alternatively, both the lower and the upper side of the building can get a same layer structure. Eine unterseitige strukturgebende Prägung hat dabei neben optischen und haptischen Effekten eine rutschhemmende Wirkung auf dem Untergrund. A bottom structuring imprint has this next visual, touch an anti-inflammatory effect on the ground. Durch die ober- und unterseitige Dekorschicht und Strukturierung lässt sich der Eindruck einer nahezu perfekten Imitation eines natürlichen Werkstoffes, zB Holz oder Stein, noch verstärken. By the upper and lower side decorative layer and structuring can be the impression of an almost perfect imitation of a natural material such as wood or stone, intensify.
  • Vorteilhafterweise sind an den Seitenkanten der Bauplatte zueinander korrespondierende Verbindungsmittel, zum Beispiel Nut und Feder, angeformt, um eine Mehrzahl von Bauplatten untereinander zu verbinden. Advantageously, at the side edges of the building board mutually corresponding connecting means, for example, tongue and groove, formed to connect a plurality of structural panels to one another. Es hat sich gezeigt, dass es besonders vorteilhaft ist, wenn an den Verbindungsmitteln mechanische Verriegelungsmittel zur Verriegelung mehrerer Bauplatten untereinander angeformt sind, damit neben der Verbindung einer Mehrzahl von Bauplatten untereinander auch eine mechanische Verriegelung der Bauplatten ohne eine zusätzliche Verleimung möglich ist. It has been found that it is particularly advantageous if mechanical locking means for locking a plurality of building boards are mutually integrally formed on the connecting means so that in addition to the connection of a plurality of building panels, a mechanical locking of the structural panels without an additional bonding to each other is possible.
  • Um einen natürlichen Werkstoff, zum Beispiel Holz oder Stein, besonders präzise zu imitieren, ist es vorteilhaft, auch auf den Kanten der Bauplatte eine den jeweiligen natürlichen Werkstoff imitierende Dekorschicht aufzubringen. A natural material, for example wood or stone, to imitate particularly precise, it is advantageous to apply also to the edges of the building board a respective imitating natural material decorative layer. Um den zu imitierenden Werkstoff noch genauer nachzubilden, ist es vorteilhaft, eine den jeweiligen natürlichen Werkstoff imitierende strukturgebende Prägung auch in die Polyurethanabdeckschicht der Seitenkanten der Bauplatte einzuprägen. In order to replicate the material to be imitated in more detail, it is advantageous to impress a respective natural material imitating structuring embossing in the Polyurethanabdeckschicht the side edges of the building board. Vorzugsweise sind dabei die Dekorschicht und/oder die strukturgebende Prägung auf das auf der Oberfläche befindliche Dekor angepasst. Preferably, the decorative layer and / or the structure-providing embossing are adapted to the top on the surface decor.
  • Das Verfahren zur Herstellung einer Bauplatte zeichnet sich dadurch aus, dass auf die Polyurethanschicht eine einen natürlichen Werkstoff imitierende Dekorschicht aufgebracht wird. The method for manufacturing a building panel is characterized in that a natural material imitating the decorative layer is applied to the polyurethane layer. Vorteilhafterweise kann die Polyurethanschicht dabei durch Aufgießen und Abrakeln aufgetragen werden, so dass eine ebene Oberfläche auf der mit einer Dekorschicht versehenen Oberseite der Bauplatte entsteht. Advantageously, the polyurethane layer may be applied by pouring and thereby scraping off, so that a flat surface is formed on the decorative layer provided with a top surface of the building board.
  • Die Dekorschicht, die auf die Polyurethanschicht aufgetragen wird, kann auch durch ein oder mehrere Walzwerke aufgetragen werden, um unterschiedlichen Farben oder mehrschichtige Dekore auf die Oberfläche der Bauplatte aufbringen zu können. The decorative layer is applied to the polyurethane layer can also be applied by one or more rolling mills, to be able to apply different colors or multilayer designs on the surface of the building board.
  • Alternativ kann die Dekorschicht auch durch mindestens einen Digitaldrucker aufgebracht werden oder im Siebdruckverfahren aufgedruckt werden. Alternatively the decorative layer may also be applied by at least one digital printer or printed thereon by screen printing. Durch die verschiedenen Möglichkeiten, die Dekorschicht auf die Oberseite der Bauplatte aufzubringen, kann auf die jeweiligen anlagentechnischen Voraussetzungen eingegangen werden. Due to the different ways of applying the decorative layer on top of the building, can be discussed in the respective plant-specific requirements.
  • Je nach optischen Erfordernissen kann die Dekorschicht in einer Schicht oder in mehreren Schichten aufgetragen werden. Depending on the optical requirements of the decorative layer can be applied in one layer or in multiple layers. Wird die Dekorschicht in mehreren Schichten aufgetragen, so kann schon durch die Dekorschicht eine reliefartige Oberfläche erzeugt werden, die eine natürliche Oberfläche, zum Beispiel eine Holzoberfläche, besonders genau imitieren kann. If the decorative layer applied in several layers, so a relief-like surface can be produced even by the decorative layer, which can mimic a natural surface, such as a wood surface, more precisely.
  • Vorteilhafterweise wird auf die Dekorschicht eine abschließende Polyurethanschicht aufgetragen, um zum einen die Dekorschicht vor Abrieb und anderen mechanischen Einflüssen zu schützen und zum anderen die schalldämmenden Eigenschaften der Bauplatte zu verbessern. Advantageously, applying a final polyurethane layer to the decorative layer in order to protect the one hand, the decorative layer from abrasion and other mechanical influences and on the other to improve the sound insulating properties of the building board.
  • Um den Auftrag der abschließenden Polyurethanschicht besonders einfach zu gestalten, kann der Auftrag durch ein Walzendruckwerk erfolgen. To particularly easy to make the order of the final polyurethane layer, the job can be done by a roll printing unit. Alternativ ist es auch möglich, die abschließende Polyurethanschicht durch Aufgießen und Abrakeln aufzubringen. Alternatively, it is also possible to apply the final polyurethane layer by pouring and doctoring. Es hat sich gezeigt, dass es vorteilhaft ist, die abschließende Polyurethanschicht in mindestens einer oder mehreren Schichten aufzutragen. It has been found that it is advantageous to apply the final layer of polyurethane in at least one or more layers. So kann eine an die jeweiligen Erfordernisse angepasste dicke oder besonders dünne abschließende Polyurethanschicht aufgetragen werden. So adapted to the respective requirements thick or particularly thin final layer of polyurethane can be applied. Zwischen dem Aufbringen der einzelnen Polyurethanschichten kann die Trocknung der jeweiligen letzten Polyurethanschicht erfolgen, um den mehrlagigen Aufbau der abschließenden Polyurethanschicht zu ermöglichen und auch besonders dicke Polyurethanschichten zu realisieren, in die besonders tiefe Prägungen eingebracht werden können. Between the application of the individual layers of polyurethane, the drying of the respective last polyurethane layer can be carried out to enable the multi-layered structure of the final polyurethane layer and also to realize particularly thick layers of polyurethane, can be incorporated in the extra deep embossments.
  • Der Trocknungsprozess kann dabei aktiv, zum Beispiel durch ein Heizgebläse, oder auch passiv, zum Beispiel durch Ablüften an der Umgebungsluft, erfolgen. The drying process can actively involved, for example, a heating fan, or passive, for example, by venting to the atmosphere, carried.
  • Die Aufteilung einer großen Bauplatte in mehrere einzelne kleine Bauplatten kann mittels einer mehrerer Aufteilsägen erfolgen. The division of a large building panel into a plurality of individual small building boards can be effected by means of a plurality of saws. Alternativ sind auch andere Aufteilverfahren, beispielsweise Wasserstrahlschneiden, einsetzbar. Alternatively, other Aufteilverfahren, such as water jet cutting, usable are.
  • Optional kann eine weitere Behandlung der Kanten vorgesehen sein. Optional further treatment of the edges may be provided. Die Kanten können mindestens teilweise dekoriert werden und/oder eine strukturgebende Prägung erhalten. The edges can be partially decorated least and / or receive a structuring embossing. Vorzugsweise ist die Dekorierung und/oder die strukturgebende Prägung auf das auf der Oberfläche befindliche Dekor angepasst.
