Abstract

The method involves applying a liquid resin i.e. melamine resin, on a top side of a construction plate that is made of wood or wood material. The resin is dried, and the plate is pressed under the influence of temperature so that the resin partially melts. The resin is applied in multiple layers and each layer is dried before the next is applied. The resin is stained. A color layer is applied on the top side or on a bottom side under or between the resin layers. Corundum is mixed into or scattered onto the resin layer. The sealing is performed simultaneously on the top and the bottom sides.

Description

Die Erfindung betrifft ein Verfahren zum Versiegeln einer Bauplatte aus Holz oder einem Holzwerkstoff mit einer Oberseite und einer Unterseite.The invention relates to a method for sealing a building board made of wood or a wood material with a top and a bottom.

Bauplatten kommen als Bodenplatten, beispielsweise als Parkett, als Schalungsplatten oder als Platten für den Möbelbau in Frage. Diese Platten sind aus Massivholz, insbesondere stäbchenverleimt, oder bestehen aus einem Kern aus Holzwerkstoff, beispielsweise MDF, HDF oder Spanplatte, auf den ein Echtholzfurnier aufgeleimt ist. Als Schalungsplatten werden hauptsächlich OSB-Platten (Oriented Strand Board) verwendet.Building boards come as floor panels, such as parquet, as formwork panels or as panels for furniture in question. These panels are made of solid wood, in particular rod-glued, or consist of a core of wood-based material, such as MDF, HDF or chipboard, on which a real wood veneer is glued. As shuttering panels mainly OSB (Oriented Strand Board) plates are used.

Die Oberfläche dieser Platten muss versiegelt werden, um sie vor Umwelteinflüssen zu bewahren. Insbesondere das Eindringen von Feuchtigkeit bei Bodenplatten muss verhindert werden. Hierzu wird die Oberfläche der Platte häufig lackiert. Lack ist relativ weich und insbesondere bei Parkettböden unterliegt die Lackschicht einem Verschleiß, so dass der Boden häufig neu versiegelt werden muss, was in geschlossenen Räumen mit entsprechenden Unannehmlichkeiten verbunden ist, da die alte Lackschicht abgeschliffen werden muss, bevor eine neue aufgebracht werden kann. Die feinen Schleifstäube setzen sich überall fest und müssen anschließend mühsam entfernt werden.The surface of these panels must be sealed in order to protect them from environmental influences. In particular, the penetration of moisture in floor slabs must be prevented. For this, the surface of the plate is often painted. Paint is relatively soft and especially in parquet floors, the paint layer is subject to wear, so that the floor must be re-sealed often, which is associated with inconvenience indoors, since the old paint layer must be sanded before a new can be applied. The fine sanding dust settles everywhere and then has to be laboriously removed.

Laminat-Paneele sind mit einer Kunstharzschicht versiegelt. Zur Herstellung von Laminat-Paneelen wird auf eine Trägerplatte aus MDF, HDF oder Span eine mit einem Dekor bedruckte Papierbahn aufgelegt, auf die ein Overlay, eine Lage aus Kunstharz oder eine mit Kunstharz getränkte Papierschicht aufgelegt wird. Anschließend wird die Platte unter Hitzeeinwirkung verpresst, wodurch sich das Overlay unter Einschluss der Papierlage mit der Oberfläche der Platte verbindet. In das vorgefertigte Overlay sind bei Bodenplatten zur Erhöhung der Abriebfestigkeit Korundpartikel eingeschlossen. Aus der so hergestellten Platte werden dann einzelne Paneele herausgesägt.Laminate panels are sealed with a synthetic resin layer. For the production of laminate panels, a paper web printed with a decor is placed on a carrier plate made of MDF, HDF or Span, onto which an overlay, a layer of synthetic resin or a resin-impregnated paper layer is applied. Subsequently, the plate is pressed under heat, whereby the overlay, including the paper layer with the surface of the plate connects. In the prefabricated overlay corundum particles are included in floor panels to increase the abrasion resistance. From the plate thus produced individual panels are sawn out.

Gegenüber einem Lack ist ein Harz nicht nur kostengünstiger, sondern auch härter. Das Auflegen der Papierbahn bzw. des vorgefertigten Overlays auf die Oberseite der Holzwerkstoffplatte muss sorgfältig erfolgen. Das Handling der sehr dünnen Schichten ist kompliziert und erfordert entsprechend präzise arbeitende Maschinenanlagen, damit sichergestellt ist, dass von einem Stapel immer nur eine einzelne Lage des Oberlays abgehoben wird. Bei einer Laminatplatte muss die Unterseite mit einem sogenannten Unterzug beschichtet werden, der von der Dekorseite herrührende Zugspannungen auf den Plattenkern ausgleicht, um ein Verbiegen der Platte, insbesondere der später ausgesägten Paneele in Längsrichtung zu verhindern.Compared to a paint is a resin not only cheaper, but also harder. The laying of the paper web or the prefabricated overlay on the top of the wood-based panel must be done carefully. The handling of the very thin layers is complicated and requires correspondingly precise machine systems, so that it is ensured that only a single layer of the upper layer is lifted from a stack. In a laminate plate, the underside must be coated with a so-called beam, which compensates for tensile stresses on the plate core originating from the decorative side, in order to prevent longitudinal bending of the plate, in particular of the later sawn-off panels.

Aus der EP -B1- 0 560 870 ist eine Parkettstruktur bekannt, bei der unterhalb der den Oberflächenlack bildenden Firnisschicht ein Füllharz oder Lack in das Innere und in die Zwischenräume der vertikalen Holzmaserungen einimprägniert ist, wobei die Menge des Lackes, bezogen auf die Menge des Parkettfirnisses ein Vielfaches beträgt. Nachdem das Füllharz eingedrungen ist, werden die Bretter vorgeheizt und absorbieren nach dem Abkühlen das Harz bis in eine ausreichende Tiefe, so dass eine "Sperrschicht" ausgebildet wird, die beim späteren Versiegeln des Parkettes ein zu tiefes Eindringen des teuren Firnisses verhindert. Durch diese Maßnahme wird bei gleich bleibendem Firnisverbrauch eine gegenüber herkömmlich versiegeltem Parkett härtere Oberfläche erzielt.From the EP-B1 0 560 870 a parquet structure is known in which below the surface varnish varnish layer a filling resin or varnish is impregnated into the interior and in the interstices of the vertical wood grains, the amount of the varnish, based on the amount of Parkettfirnisses a multiple. After the filling resin has penetrated, the boards are preheated and, after cooling, absorb the resin to a sufficient depth to form a "barrier layer" which prevents the expensive varnish from penetrating too deeply when the parquet is subsequently sealed. By this measure, a surface harder compared to conventionally sealed parquet is achieved with constant Varnish consumption.

Aus der DE -C2- 37 35 368 ist es bekannt, auf eine Materialplatte eine pulverförmige Harzschicht aufzustreuen, auf die anschließend noch Einlagestücke aufgebracht werden. Anschließend wird die Pulverschicht warm verpresst, um das Harz zu schmelzen und mit der Platte zu verbinden.From the DE-C 2-3 37 35 368 It is known to sprinkle on a sheet of material, a powdery resin layer on which subsequently inserts are applied. Subsequently, the powder layer is pressed hot to the resin melt and connect to the plate.

Von dieser Problemstellung ausgehend soll ein Verfahren zum Versiegeln einer Bauplatte aus Holz oder einem Holzwerkstoff mit einer Echtholzoberfläche angegeben werden, mit dem die von Laminatplatten bekannte verschleißfeste Oberfläche erzielbar ist, das aber einfacher und schneller ausgeführt werden kann.Starting from this problem, a method for sealing a building board made of wood or a wood-based material with a real wood surface should be specified, with which the known from laminate sheets wear-resistant surface can be achieved, but which can be performed easier and faster.

Die Problemlösung erfolgt durch folgende Schritte:

  1. a) Auftragen von flüssigem Harz auf die Oberseite,
  2. b) Trocknen des Harzes,
  3. c) Verpressen der Bauplatte unter Temperatureinfluss, wobei das Harz zumindest teilweise schmilzt,
  4. d) Einprägen eines zu der Holzmaserung korrespondierenden Reliefs.
The problem solution is done by the following steps:
  1. a) applying liquid resin to the top,
  2. b) drying the resin,
  3. c) pressing the building board under the influence of temperature, wherein the resin at least partially melts,
  4. d) imprinting a relief corresponding to the wood grain.

Das flüssige Harz kann aufgewalzt, aufgesprüht oder aufgegossen werden. Es ist wesentlich einfacher zu handhaben, als eine vorgefertigte Harzlage. Wird die Harzschicht entsprechend dick aufgetragen, stellt sich die von Laminatplatten bekannte Oberflächenhärte ein. Es kann also eine Bauplatte geschaffen werden, die die positiven Eigenschaften von Massivholz bzw. furniertem Holzwerkstoff mit den positiven Eigenschaften von Laminat vereinbart. Durch das wesentlich härtere Harz wird die sehr hohe Verschleißfestigkeit erzeugt, die noch gesteigert werden kann, indem in das flüssige Harz Korundpartikel eingemischt oder eingestreut werden. Um die Haptik der versiegelten Oberfläche an die von unversiegeltem Holz anzupassen, ist in die Harzschicht ein Relief eingeprägt, das zu (dem Dekor) der Holzmaserung korrespondiert.The liquid resin can be rolled, sprayed or poured. It is much easier to handle than a prefabricated resin layer. If the resin layer is applied thick enough, the surface hardness known from laminate boards sets. So it can be created a building board, which agrees the positive characteristics of solid wood or veneered wood material with the positive properties of laminate. Due to the much tougher resin, the very high wear resistance is generated, which can be further increased by mixing or sprinkling corundum particles into the liquid resin. In order to adapt the feel of the sealed surface to that of unsealed wood, a relief is imprinted in the resin layer, which corresponds to the (wood) of the wood grain.

Durch die Verwendung entsprechend polierter Pressbleche in der Presse können beim Verpressen der Bauplatte Glanzgrade eingestellt werden. Ein hochglanzpoliertes Pressblech führt zu einer hochglänzenden oder gar spiegelnden Oberfläche. Hierdurch lassen sich besonders schöne optische Effekte erzielen. Vor dem Aufbringen der Harzschicht kann eine OSB-Platte gespachtelt werden, um Unebenheiten in der Oberfläche zu beseitigen.By using correspondingly polished press plates in the press, gloss levels can be set when pressing the building board. A highly polished pressed sheet leads to a high-glossy or even reflective surface. This makes it possible to achieve particularly beautiful optical effects. Before applying the resin layer, an OSB board can be troweled to remove surface unevenness.

Auf dieselbe Art und Weise kann auch die Unterseite der Bauplatte versiegelt werden. Dann können insbesondere OSB-Platten, die eine sehr hohe Festigkeit aufweisen, als Betonschalungsplatten verwendet werden. Die Kunstharzschicht verhindert nicht nur das Eindringen von Feuchtigkeit in die Schalungsplatte, sondern erhöht auch ihre Lebensdauer aufgrund der Härte der Oberfläche.In the same way, the underside of the building board can be sealed. Then, in particular, OSB boards having a very high strength can be used as concrete shuttering boards. The resin layer not only prevents the penetration of moisture into the formwork panel, but also increases its life due to the hardness of the surface.

Das Harz kann in mehreren Schichten aufgetragen werden, wobei jede Schicht vor dem Auftragen einer nächsten getrocknet wird.The resin can be applied in multiple layers, with each layer being dried before applying another.

Vorzugsweise ist das Harz ein Kunstharz, insbesondere Melaminharz.Preferably, the resin is a synthetic resin, in particular melamine resin.

Um besondere optische Effekte zu erzielen, kann das Harz eingefärbt sein. Auf der Oberseite und/oder Unterseite kann zwischen den Harzschichten eine Farbschicht aufgetragen werden. Die Farbschicht kann aufgedruckt werden. Das hat den Vorteil, dass das Dekor auch noch veredelt werden kann. Beispielsweise kann auf ein Kiefernfurnier ein Eiche- oder Palisanderdekor mit entsprechender Maserung und Farbgebung aufgedruckt werden, wodurch die Echtholzoberfläche aufgewertet wird.To achieve special optical effects, the resin may be colored. On the top and / or bottom, a coat of paint can be applied between the resin layers. The color layer can be printed. This has the advantage that the decor can also be finished. For example, an oak or rosewood decor with corresponding grain and color can be printed on a pine veneer, whereby the real wood surface is upgraded.

Auch können weitere Füllstoffe in die Harzschicht eingemischt oder auf einzelne Schichten aufgestreut werden. Durch Aufbringen einer solchen Schicht an der Unterseite können hierdurch beispielsweise die Trittschalleigenschaften einer Bodenplatte verbessert werden.Also, other fillers can be mixed in the resin layer or sprinkled on individual layers. By applying such a layer on the underside, for example, the footfall sound properties of a floor panel can be improved.

Die Ober- und die Unterseite werden vorzugsweise gleichzeitig beschichtet. Dadurch werden nicht nur völlig neue und verbesserte Produkteigenschaften erzielt, sondern gleichzeitig werden auch die Kosten für die Herstellung der Bauplatte wesentlich gesenkt.The top and bottom are preferably coated simultaneously. As a result, not only are completely new and improved product properties achieved, but at the same time the costs for the production of the building board are substantially reduced.
