Description

Die Erfindung betrifft ein Verfahren zum Veredeln einer Holzwerkstoffplatte, beispielsweise eine MDF- oder HDF-Platte.The invention relates to a method for refining a wood-based panel, such as an MDF or HDF board.

Aus der WO 2005/010296 ist ein Fußbodenlaminat mit einer unterseitigen Trägerplatte bekannt, die an zumindest einem Paar gegenüberliegender Kanten eine Nut-/Federverbindung aufweist, und die mit einer oberseitigen Nutz- und Verschleißschicht versehen ist, an die unterseitig eine zwischen der Trägerplatte und der Nutz-und Verschleißschicht vorgesehene Dekorschicht angrenzt. Damit das Fußbodenlaminat eine Dielenoptik unabhängig von der Breite und der Länge der Trägerplatte bekommt, ist oberseitig eine sich zwischen zwei gegenüberliegenden Kanten erstreckende und parallel zu einem Paar gegenüberliegender Kanten ausgerichtete Vertiefung vorgesehen, über die sich sowohl die Dekorschicht als auch die Nutz- und Verschleißschicht erstreckt.From the WO 2005/010296 is a floor laminate with a lower-side support plate is known which has a tongue and groove on at least one pair of opposite edges, and which is provided with an upper side wear and wear layer, to the underside a provided between the support plate and the Nutz- and wear layer decorative layer borders. So that the floor laminate gets a plank look irrespective of the width and the length of the support plate, a recess extending between two opposite edges and oriented parallel to a pair of opposite edges is provided on top, over which extends both the decorative layer and the wear and tear layer ,

Die Dekorschicht kann aufgedruckt sein. Häufig werden zur Lackierung oder zur Versiegelung von Holz- und Holzwerkstoffplatten Lacke eingesetzt, die durch energiereiche Elektronenstrahlen aushärtbar sind (ESH-Lacke) oder UV-Lacke mit einer vergleichsweise gering vernetzten Struktur, um hochglänzende Oberflächen zu erhalten.The decorative layer may be printed. Often lacquers are used for painting or sealing of wood and wood-based panels, which are high-energy Electron beams are curable (ESH paints) or UV coatings with a comparatively low crosslinked structure to obtain high-gloss surfaces.

Um Strukturen in die Oberfläche zu bekommen, werden Strukturgeber verwendet. Hierbei handelt es sich um lackierte und strukturierte Papiere, die als Matrize für Oberflächenstrukturen eingesetzt werden. Sie kommen während des eigentlichen Lackierprozesses zur Anwendung. Diese Strukturgeber ermöglichen nur die Erzeugung von relativ flachen und wenig strukturierten Oberflächen. Die Erzeugung scharfkantiger und/oder tiefer Strukturen ist nicht möglich.Structurers are used to get structures into the surface. These are lacquered and structured papers that are used as a template for surface structures. They are used during the actual painting process. These structurizers only allow the creation of relatively flat and poorly textured surfaces. The production of sharp-edged and / or deep structures is not possible.

Es ist auch bekannt, Chemikalien zu verwenden, die den Verlauf der Lacke gezielt beeinflussen und damit durch gezielte Verlaufstörungen Strukturierungen erzeugen. Dieses Verfahren reduziert sich auf Produkte, bei denen zuvor in einem separaten Schritt die entsprechenden Mittel aufgebracht werden. Das Verfahren ist auf Produkte begrenzt, bei denen geringe Lackmengen aufgetragen werden. Bei Produkten mit hoher mechanischer Beanspruchung, wie z. B. Fußböden, kann diese Technologie nicht angewendet werden.It is also known to use chemicals that specifically influence the course of the coatings and thus produce structured by targeted flow disturbances. This process is reduced to products in which the corresponding agents are previously applied in a separate step. The process is limited to products in which small amounts of paint are applied. For products with high mechanical stress, such. As flooring, this technology can not be applied.

Der Erfindung liegt die Aufgabe zugrunde, die Oberfläche einer Holzwerkstoffplatte, die beispielsweise anschließend zu Fußbodenpaneelen weiterverarbeitet oder als Möbelplatte verwendet werden kann, zu veredeln. Die Lösung der Aufgabe erfolgt mit folgenden Schritten:

  1. a) Aufbringen einer Dekorschicht auf die Oberseite,
  2. b) Aufbringen einer versiegelnden Lackschicht auf die Dekorschicht,
  3. c) vollständiges Aushärten der Lackschicht mittels Elektronenstrahlen und
  4. d) Einprägen einer Struktur in die Lackschicht.
The invention has for its object to refine the surface of a wood-based panel that can be further processed, for example, then to floor panels or used as a furniture panel. The task is solved with the following steps:
  1. a) applying a decorative layer on top,
  2. b) applying a sealing lacquer layer to the decorative layer,
  3. c) complete curing of the lacquer layer by means of electron beams and
  4. d) embossing a structure in the lacquer layer.

Die Strukturierung erfolgt durch in-line oder off-line mit einem Prägekalander oder einer Taktpresse unter Temperatur- und Druckbeaufschlagung. Die Temperatur liegt im Bereich von 80 bis 150 °C und der Druck in einem Bereich von 15 bis 40 bar. Vorzugsweise liegt die Temperatur bei 100 °C und der Druck bei 25 bar.The structuring is done by in-line or off-line with an embossing calender or a cycle press under temperature and pressure. The temperature is in the range of 80 to 150 ° C and the pressure in a range of 15 to 40 bar. Preferably, the temperature is 100 ° C and the pressure is 25 bar.

Je nach Schichtdicke des Lackes und der Prägetiefe des Bleches können Strukturtiefen von 50 bis 250 µm, vorzugsweise 100 bis 200 µm, erzielt werden.Depending on the layer thickness of the paint and the embossing depth of the sheet structure depths of 50 to 250 .mu.m, preferably 100 to 200 microns, can be achieved.

In einer stationären Presse können Presszeiten im einstelligen Sekundenbereich realisiert werden. Die durch die Matrize des Pressbleches bzw. der Kalanderwalze vorgegebenen Oberflächen können auf das genaueste abgebildet werden.Press times in the single-digit range can be realized in a stationary press. The surfaces defined by the die of the press plate or the calender roll can be imaged in the most accurate way.

Vor dem Aufbringen der Dekorschicht auf die Oberseite der Trägerplatte kann zuvor eine Trägerschicht, die vorzugsweise eine aufgedruckte Farbschicht ist, aufgebracht werden. Die Trägerschicht kann auch aus Papier bestehen. Bevorzugt ist das Dekor der Dekorschicht eine Holz- oder Steinreproduktion.Before the decorative layer is applied to the upper side of the carrier plate, a carrier layer, which is preferably a printed ink layer, can be applied beforehand. The carrier layer may also consist of paper. Preferably, the decor of the decorative layer is a wood or stone reproduction.

Eine besonders natürliche Optik der veredelten Holzwerkstoffplatte wird erzielt, wenn die in die Lackschicht eingeprägte Struktur zu der Maserung des Holzdekors bzw. der Aderung der Steinreproduktion korrespondiert.A particularly natural appearance of the finished wood-based panel is achieved if the structure embossed into the lacquer layer corresponds to the grain of the wood decor or the veining of the stone reproduction.

Die mechanische Beanspruchung des Lackfilms beim Prägen führt zu keiner Schwächung des Verbundes und auch zu keiner qualitativen Verschlechterung der Oberfläche.The mechanical stress of the paint film during embossing leads to no weakening of the bond and also to no qualitative deterioration of the surface.

Anstelle eines Holzdekors kann auch eine Kork-, Leder- oder Fliesenoptik hergestellt werden. Das Einprägen der Struktur kann kontinuierlich oder diskontinuierlich erfolgen. Durch das Einprägen wird die Oberflächenruhe erhöht. Aus der so hergestellten Holzwerkstoffplatte können optisch ansprechende Paneele, insbesondere Fußbodenpaneele, zugeschnitten werden.Instead of a wood decor, a cork, leather or tile look can be made. The embossing of the structure can be continuous or discontinuous. By impressing the surface peace is increased. Optically attractive panels, in particular floor panels, can be cut from the wood-based panel so produced.

Es wurde beispielsweise eine HWS-Platte im Tiefdruck mit einem Holzdekor bedruckt. Dabei wurde ein elektronenstrahlhärtbarer Lack mit verschleiß- und kratzhemmenden Zusatzstoffen verwendet, von dem ca. 150 g/m2 aufgetragen worden sind. Die Lackschicht wurde mit einem Elektronenstrahl mit einer Dosisleistung von 60 kGray vollständig ausgehärtet. Ein Pressblech, in das eine dem Dekor angepasste Holzpore eingraviert wurde, wurde bei einer Temperatur von 100 °C und einem Druck von 35 bar für 15 Sekunden auf die Oberseite der Holzwerkstoffplatte aufgelegt. Nach der Strukturierung stellte sich ein Glanzgrad von 93 Punkten (60°) ein, der vor der Strukturierung 88 Punkte (60°) betragen hat (Messung nach EN ISO2813: Beschichtungsstoffe - Bestimmung des Reflektometerwertes von Beschichtungen (außer Metallbeschichtungen) unter 20°, 60° und 85° ((ISO 2813: 1994, einschließlich technischer Korrektur 1: 1997)).For example, a cervical spine plate was gravure printed with a wood decor. In this case, an electron beam curable varnish with wear and scratch-inhibiting additives was used, of which about 150 g / m 2 have been applied. The lacquer layer was completely cured with an electron beam with a dose rate of 60 kGray. A press plate, in which a wooden pore adapted to the decor was engraved, was placed on top of the wood-based panel at a temperature of 100 ° C. and a pressure of 35 bar for 15 seconds. After structuring, a gloss level of 93 points (60 °) was reached, which amounted to 88 points (60 °) before structuring (measurement according to EN ISO2813: Paints and varnishes - Determination of the reflectometer value of coatings (except metal coatings) below 20 °, 60 ° and 85 ° ((ISO 2813: 1994, including technical correction 1: 1997)).
