Description

Die Erfindung betrifft eine Holzwerkstoffplatte mit einem Kern aus OSB (Oriented Strand Board) und einer Deckschicht aus Holz.The The invention relates to a wood-based panel having a core of OSB (Oriented beach board) and a top layer of wood.

Eine solche Platte ist beispielsweise aus der DE 297 22 941 U1 bekannt. Zumindest einseitig ist auf den OSB-Kern ein Echtholzfurnier in einer Stärke von etwa 1,5 mm aufgeklebt.Such a plate is for example from the DE 297 22 941 U1 known. At least on one side is glued to the OSB core a real wood veneer in a thickness of about 1.5 mm.

Eine OSB-Platte besteht aus mehreren Schichten großer Späne, die zu Lagen gestreut wurden, die jeweils anders ausgerichtet sind, um eine hohe Stabilität der Platte zu erhalten. Durch die großflächigen Späne ist die Oberfläche der OSB-Platte nicht plan. Damit die Platte beschichtet werden kann, muss die Oberfläche zunächst sehr sorgfältig gespachtelt und/oder geschliffen werden, um später eine gute Verklebung zwischen dem Kern und der Dekorschicht zu erzielen und eine attraktive glatte Sichtseite zu erzielen.A OSB board consists of several layers of large shavings that have been spread to layers, which are each oriented differently to ensure high stability of the plate to obtain. Due to the large chips is the surface the OSB board not plan. In order for the plate to be coated, the surface must first be very careful be smoothed and / or sanded to get a good bond between later to achieve the core and the decorative layer and an attractive smooth visual side to achieve.

In der Regel hat OSB keine einheitliche Oberflächenfarbe, so dass bei dünnen und hellen Furnieren die Gefahr besteht, dass der OSB-Kern oder zumindest ein Teil davon an der Sichtseite durchscheint.In usually OSB has no uniform surface color, so thin and bright veneers there is a risk that the OSB core or at least a part of it on the visible side shines through.

Aus der DE 299 04 919 U1 ist eine OSB-Platte bekannt, auf die beidseitig eine HDF-Platte aufgeklebt ist, die eine sehr glatte Oberfläche aufweist. Auf diese HDF-Platte kann dann auch eine relativ dünne Dekorschicht aufgebracht werden.From the DE 299 04 919 U1 is an OSB board is known to which is glued on both sides of an HDF board, which has a very smooth surface. On this HDF plate can then be applied a relatively thin decorative layer.

Aus der DE 26 24 643 A1 oder der US 4,364,984 ist es beispielsweise bekannt, bei der Herstellung einer OSB-Platte in die Deckschicht sehr feine Späne einzustreuen, um eine glatte Oberfläche zu erhalten.From the DE 26 24 643 A1 or the US 4,364,984 For example, in the manufacture of an OSB board, it is known to scatter very fine chips to obtain a smooth surface.

Der Vorteil einer OSB-Platte besteht darin, dass sie gegenüber einer herkömmlichen Spanplatte eine hohe Biegefestigkeit besitzt und auch sonst wesentlich verbesserte mechanische Eigenschaften aufweist. Die glatte Oberfläche einer Holzwerkstoffplatte ist nur dann notwendig, wenn sie beschichtet werden soll, um beispielsweise im Möbelbau oder beim Innenausbau (Bodenpaneele) verwendet zu werden. Allen vorstehend beschriebenen Platten gemeinsam ist der hohe mit der Erzielung einer glatten Oberfläche verbundene Aufwand. Trotz der guten mechanischen Eigenschaften wird eine OSB-Platte deshalb in der Praxis nicht als Kernmaterial verwendet, sondern kommt in der Regel nur dann zum Einsatz, wenn keine besonderen Anforderungen an die Optik gestellt werden.Of the The advantage of an OSB board is that it faces one usual Chipboard has a high bending strength and otherwise essential has improved mechanical properties. The smooth surface of a Wood-based panels are only necessary if they are coated should, for example, in furniture or to be used in interior construction (floor panels). all common plates described above is the high with the Achieving a smooth surface connected expenses. Despite the good mechanical properties is Therefore, an OSB board is not used as core material in practice. but is usually used only if no special Requirements are placed on the optics.

Die US 5,925,211 A offenbart eine Holzwerkstoffplatte, bei der eine Furnierschicht mit dem Holzwerkstoff-Kern über eine harzlaminierte Papierlage erfolgt. Als Kernmaterial kommt Spanplatte oder HDF/MDF in Frage.The US 5,925,211 A discloses a wood-based panel in which a veneer layer is made with the wood-based core over a resin-laminated paper sheet. The core material is chipboard or HDF / MDF.

Von dieser Problemstellung ausgehend soll die eingangs erläuterte Holzwerkstoffplatte so verbessert werden, dass die Beschichtung der Sichtseite einfach ist und eine qualitativ hochwertige Oberfläche erhalten wird, wobei gegenüber den bekannten Platten die Herstellung vereinfacht werden soll.From Based on this problem, the initially explained wood-based panel be improved so that the coating of the visible side easy is and a high quality surface is obtained, being compared to the known plates production is to be simplified.

Zur Problemlösung zeichnet sich eine gattungsgemäße Holzwerkstoffplatte dadurch aus, dass zwischen dem OSB-Kern und der Deckschicht eine harzgetränkte Papierlage angeordnet ist und die Deckschicht, die Papierlage und der OSB-Kern unter Druck- und Temperatureinwirkung miteinander verpresst sind, dass Unebenheiten in der Oberfläche des OSB-Kerns durch einen aufgeschmolzenen Harzanteil der Papierlage ausgeglichen sind und dass die Papierlage eine Farbe aufweist, die ein Durchscheinen des OSB-Kerns verhindert.to Troubleshooting is a generic wood-based panel characterized in that between the OSB core and the cover layer, a resin-impregnated paper layer is arranged and the top layer, the paper layer and the OSB core are pressed together under pressure and temperature, that bumps in the surface of the OSB core by a melted resin portion of the paper layer are balanced and that the paper layer has a color that prevents the OSB core from showing through.

Das Flächengewicht der Papierlage beträgt vorzugsweise 20 bis 90 Gramm pro Quadratmeter.The grammage the paper layer is preferably 20 to 90 grams per square meter.

Die harzgetränkte Papierlage wird auf die unbearbeitete Oberfläche des OSB-Kerns aufgelegt. Auf die Papierlage wird die Deckschicht aufgelegt und dann alle Schichten miteinander unter Druck- und Temperatureinwirkung miteinander verpresst.The resin-impregnated Paper layer is placed on the untreated surface of the OSB core. On the paper layer is applied to the topcoat and then all layers pressed together under pressure and temperature influence.

Durch den aufschmelzenden Harzanteil gleicht die Papierlage zunächst einmal die Unebenheiten in der Oberfläche des OSB-Kerns aus. Gleichzeitig sorgt der Harzanteil beim Verpressen auch für die Haftung der Deckschicht am Kern. Die Papierlage hat außerdem den Vorteil, dass sie in jeder gewünschten Farbe zur Verfügung gestellt werden kann, so dass auch bei hellen Furnieren ein Durchscheinen der OSB-Strands bei unterschiedlicher Farbgebung wirksam verhindert wird.By the melting point of the resin equalizes the paper layer at first the bumps in the surface of the OSB core. At the same time, the resin content ensures during pressing also for them Adhesion of the cover layer to the core. The paper layer also has the Advantage that they are in every desired Color available can be made, so that even with bright veneers a show through the OSB beaches is effectively prevented with different colors.

Auf der der Deckschicht gegenüberliegenden Seite des Kerns ist vorzugsweise eine Schicht als Gegenzug angebracht, die einem Verbiegen der Platte entgegenwirkt und auf den Kern ähnliche Zugkräfte ausübt wie die Papierlage und die Deckschicht.On the opposite of the top layer Side of the core is preferably a layer attached in return, which counteracts bending of the plate and similar to the core tensile forces exerts like the paper layer and the top layer.

Die erfindungsgemäße Holzwerkstoffplatte eignet sich besonders gut für die Herstellung von Fussbodenpaneelen. Als Deckschicht kann ein Furnier von 2–5 mm Dicke verwendet werden. In zumindest zwei gegenüberliegende Seitenkanten der Bodenpaneele können Feder/Nut eingefräst werden.The wood-based panel according to the invention is particularly suitable for the production of floor panels. As cover layer a veneer of 2-5 mm thickness can be used. In at least two opposite side edges of the Bo The panels can be milled in spring / groove.

Die Stärke des Kerns ist beliebig und wird durch den Einsatzfall bestimmt. Je höher die mechanische Beanspruchung ist, umso dicker wird der Kern gewählt werden. Gegenüber einer herkömmlichen Spanplatte als Kernmaterial für Fussboden-Parkett hat der OSB-Kern den Vorteil der höheren mechanischen Festigkeit, was dazu führt, dass ein Ausbrechen der Kanten bei unsachgemäßer Handhabung der Paneele während des Verlegens oder beim Transport deutlich reduziert ist.The Strength The core is arbitrary and determined by the application. The higher the mechanical stress is, the thicker the core will be chosen. Across from a conventional chipboard as nuclear material for Flooring parquet, the OSB core has the advantage of higher mechanical Strength, which leads to that a breaking of the edges in case of improper handling of the panels while laying or during transport is significantly reduced.
