Description

Die Erfindung betrifft eine Holzwerkstoffplatte, insbesondere eine OSB-, Span-, Sperrholz- oder Faserplatte (MDF, HDF), die mindestens eine obere Deckschicht, mindestens eine Mittelschicht und mindestens eine untere Deckschicht aufweist.The invention relates to a wood-based panel, in particular an OSB, chip, plywood or fiber board (MDF, HDF), which has at least one upper cover layer, at least one middle layer and at least one lower cover layer.

Eine solche Holzwerkstoffplatte ist beispielsweise aus der EP 1 754 583 A1 bekannt. Bei dieser Holzwerkstoffplatte bestehen die Schichten allesamt aus harzbeleimten Strands. Zur Herstellung werden die mit Harz beleimten Strands separat bereitgestellt, die Strands der unteren Deckschicht in einer ersten Orientierung im Wesentlichen längs zur Plattenhauptrichtung abgelegt, die Strands der Mittelschicht in einer zweiten Orientierung im Wesentlichen quer zur Plattenhauptrichtung auf die untere Deckschicht abgelegt, und die Strands der oberen Deckschicht werden in der ersten Orientierung auf die Mittelschicht abgelegt und dieser Schichtaufbau dann unter erhöhtem Druck und unter erhöhter Temperatur verpresst.Such a wood-based panel is for example from the EP 1 754 583 A1 known. In this wood-based panel, the layers are all made of resin-glued strands. For preparation, the resin coated strands are provided separately, the strands of the lower cover layer laid down in a first orientation substantially longitudinal to the plate main direction, the strands of the middle layer deposited in a second orientation substantially transverse to the plate main direction on the lower cover layer, and the strands of the upper cover layer are deposited in the first orientation on the middle layer and then pressed this layer structure under increased pressure and elevated temperature.

Holzwerkstoffplatten stellen sehr hochwertige Produkte dar, die aber spezifischen Begrenzungen unterworfen sind, wobei in erster Linie die mechanischen Eigenschaften, wie z. B. Biegesteifigkeit, E-Modul und Querzugfestigkeit gemeint sind. Wenn Holzwerkstoffplatten als Bauplatten eingesetzt werden, ist ein weiterer wesentlicher Nachteil ihre erhöhte Brennbarkeit aufgrund des verwendeten lignocellulosehaltigen Materials. Insbesondere im Baubereich besteht ein zunehmender Bedarf an Holzwerkstoffplatten, die bei vergleichsweise geringer Plattenstärke hohe Festigkeitseigenschaften aufweisen, damit sie aufgrund ihres geringen Gewichtes einfach zu handhaben sind.Wood-based panels represent very high quality products, but are subject to specific limitations, with the mechanical properties, such as. B. flexural strength, modulus and transverse tensile strength are meant. If wood-based panels are used as structural panels, another significant disadvantage is their increased flammability due to the lignocellulosic material used. Especially in the construction sector, there is an increasing demand for wood-based panels, which have high strength properties at comparatively low plate thickness, so that they are easy to handle due to their low weight.

Um die mechanischen Festigkeiten der vorgenannten Holzwerkstoffplatte zu verbessern, ist vorgesehen, Gewebefasern unterschiedlicher Länge, Dicke und Beschaffenheit in die Deckschichten einzubringen. Durch das Einbringen einer definierten Menge von Gewebefasern kann die Zugfestigkeit der Decklagen auf den jeweiligen späteren Verwendungszweck eingestellt werden. Hierzu können die obere und/oder untere Deckschicht auch mindestens eine Gewebelage aufweisen. Die Gewebelage kann z. B. in Form einer Gewebematte aufgebracht werden, wodurch die Biegeeigenschaften einer OSB-Platte erhöht werden.In order to improve the mechanical strengths of the aforementioned wood-based panel, is intended to introduce fabric fibers of different lengths, thickness and texture in the outer layers. By introducing a defined amount of fabric fibers, the tensile strength of the cover layers can be adjusted to the respective later intended use. For this purpose, the upper and / or lower cover layer may also have at least one fabric layer. The fabric layer can z. B. be applied in the form of a fabric mat, whereby the bending properties of an OSB board are increased.

Aus der DE 1 945 779 A ist eine faserverstärkte Platte mit auf einer Kernschicht aus Holz oder Holzwerkstoff angeordneter Verstärkungsschicht aus Glasfaserwerkstoff oder dergleichen bekannt. Diese Verstärkungsschicht befindet sich beidseitig in einer Verbindungsschicht aus beim Härten schrumpfendem Kunststoff, wie beispielsweise Polyesterharz. Die äußere auf die Verstärkungsschicht aufgetragene Verbindungsschicht wird von einer Schutzschicht aus Kunststoff-Folie überdeckt. Die Schutzfolie soll ein Heraustreten des Faserwerkstoffes bei Bewitterung vermeiden.From the DE 1 945 779 A For example, a fiber reinforced board having a reinforcing layer of glass fiber material or the like disposed on a core layer of wood or wood material is known. This reinforcing layer is located on both sides in a bonding layer of plastic shrinking during curing, such as polyester resin. The outer bonding layer applied to the reinforcing layer is covered by a protective layer of plastic film. The protective film should prevent the fiber material from coming out when it is weathered.

Aus der US 4,058,580 A oder der DE 25 54 212 A1 ist ein verstärktes Formteil aus einem zusammengepressten Gemisch aus zerkleinerten, feinteiligen Lignocellulose-Teilchen und Bindemittel bekannt, in das eine Vielzahl von durchgehenden, endlosen, langen verstärkenden Fäden eingebettet ist. Die verstärkenden Fäden weisen eine Zugfestigkeit und Elastizität auf, die wesentlich größer ist, als die Zugfestigkeit und die Elastizität des gebundenen Gemisches. Die verstärkenden Fäden sind weitgehend gerade in einer vorgegebenen Richtung und parallel im seitlichen Abstand zueinander angeordnet. Die verstärkenden Fäden weisen eine Länge auf, um durchgehend in der vorgegebenen Richtung von einer Seite zur gegenüberliegenden Seite des Formteiles zu reichen, und sie sind im Wesentlichen über ihre gesamte Länge über das Bindemittel an die Lignocellulose-Teilchen gebunden. Als Material für die verstärkenden Fäden kommen Glasfasern oder Stahldrähte in Betracht, da sie gut an den Bindemitteln haften und preiswert zu beschaffen sind.From the US 4,058,580 A or the DE 25 54 212 A1 For example, a reinforced molding of a compressed mixture of comminuted, finely divided lignocellulosic particles and binder is known in which a plurality of continuous, endless, long reinforcing threads is embedded. The reinforcing threads have a tensile strength and elasticity that is substantially greater than the tensile strength and elasticity of the bonded mixture. The reinforcing threads are arranged largely straight in a predetermined direction and parallel to each other in the lateral distance. The reinforcing filaments have a length to extend continuously in the predetermined direction from one side to the opposite side of the molded article, and they are bonded to the lignocellulosic particles over substantially the entire length thereof via the binder. The material for the reinforcing threads are glass fibers or steel wires into consideration, since they adhere well to the binders and are inexpensive to procure.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, die eingangs erläuterte Holzwerkstoffplatte dahingehend zu verbessern, dass nicht nur ihre mechanischtechnologischen Eigenschaften deutlich steigen, sondern auch ihre Eigenschaften im Brandfall verbessert werden.Proceeding from this, the invention has the object to improve the wood-based panel initially explained to the effect that not only their mechanical properties increase significantly, but also their properties are improved in case of fire.

Zur Problemlösung zeichnet sich eine gattungsgemäße Holzwerkstoffplatte dadurch aus, dass nur in der oberen und/oder der unteren Deckschicht Glasfasern oder Steinwollefasern enthalten sind.To solve the problem, a generic wood-based panel characterized by the fact that only in the upper and / or the lower cover layer glass fibers or rock wool fibers are included.

Dadurch, dass die Glasfasern oder Steinwollefasern nur in der oder den Deckschichten enthalten sind, wird das Gewicht der Holzwerkstoffplatte niedrig gehalten. Gleichzeitig wird aber eine Versteifung und insbesondere eine Erhöhung der Zugfestigkeit in dem Bereich zur Verfügung gestellt, in dem die höchste Belastung auftritt, wenn die Holzwerkstoffplatte als Bauplatte eingesetzt wird. Durch die Einbindung nicht brennbarer Fasern in den Plattenaufbau, wird die Brennbarkeit der Holzwerkstoffplatte deutlich reduziert bzw. ihre Feuerbeständigkeit deutlich erhöht.The fact that the glass fibers or rockwool fibers are contained only in the or the outer layers, the weight of the wood-based panel is kept low. At the same time, however, a stiffening and in particular an increase in the tensile strength is provided in the area in which the highest load occurs when the wood-based panel is used as a building board. By incorporating non-flammable fibers into the panel structure, the flammability of the wood-based panel is significantly reduced or its fire resistance significantly increased.

Vorzugsweise weisen die obere und/oder untere Deckschicht ausschließlich Glasfasern oder Steinwollefasern auf. Die Stabilität der Platte wird dadurch weiter verbessert und auch ihre Brennbarkeit weiter reduziert. Die obere und/oder untere Deckschicht könne aus einem Vlies aus Glasfaser oder Steinwollefaser bestehen, dass entweder aufgeklebt oder bei der Herstellung der Holzwerkstoffplatte mit den übrigen Schichten verpresst worden ist.Preferably, the upper and / or lower cover layer exclusively on glass fibers or rock wool fibers. The stability of the plate is thereby further improved and their flammability further reduced. The upper and / or lower cover layer may consist of a fleece of glass fiber or rockwool fiber, which has either been glued or pressed in the production of the wood-based panel with the other layers.

Die obere und/oder untere Deckschicht könnte aber auch aus einem lignocellulosehaltigen Material bestehen, in das zusätzlich Glasfasern oder Steinwollefasern eingebracht sind. Zur Verbindung der Glasfasern oder Steinwollefasern mit dem lignocellulosehaltigen Material werden vorzugsweise Phenol-Formaldehyd-Resole oder Phenol-Formaldehyd-Novolake eingesetzt.However, the upper and / or lower cover layer could also consist of a lignocellulose-containing material into which glass fibers or rockwool fibers are additionally introduced. Phenol-formaldehyde resoles or phenol-formaldehyde novolaks are preferably used to compound the glass fibers or rock wool fibers with the lignocellulose-containing material.

Es können des Weiteren Brand- und/oder Flammschutzmittel, VOC- und Formaldehydfänger, Fungizide und/oder Mittel gegen Termitenbefall zugesetzt werden, um die Eigenschaften der Platte weiter zu verbessern. Diese Zusätze können kumulativ oder alternativ beigemischt sein.Furthermore, fire and / or flame retardants, VOC and formaldehyde scavengers, fungicides and / or termite attack agents can be added to further improve the properties of the board. These additives may be added cumulatively or alternatively.

Mit Hilfe einer Zeichnung sollen Ausführungsbeispiele der Erfindung nachfolgend näher beschrieben werden.With the help of a drawing, embodiments of the invention will be described in more detail below.

Die Holzfaserplatte 1 kann, wie in Figur 3 dargestellt ist, aus drei Schichten 2, 3, 4 aus lignocellulosehaltigem Material, beispielsweise Holzspäne oder Holzfasern, gestreut sein. Die obere Deckschicht 5 und die untere Deckschicht 6 bestehen aus Glasfasern oder Steinwollefasern. Diese könne als Vlies zur Verfügung gestellt sein, und auf die obere Schicht 4 bzw. die untere Schicht 2 aufgeklebt werden. Es ist auch möglich wie nachfolgend näher noch beschrieben wird, die Glasfasern bzw. Steinwollefasern aufzustreuen und dann mit den gestreuten Schichten 2, 3, 4 zu verpressen.The fiberboard 1 can, as in FIG. 3 is shown, from three layers 2, 3, 4 of lignocellulosic material, such as wood chips or wood fibers, be scattered. The upper cover layer 5 and the lower cover layer 6 are made of glass fibers or rock wool fibers. This could be provided as a nonwoven, and glued to the upper layer 4 and the lower layer 2. It is also possible, as described in more detail below, to sprinkle the glass fibers or rock wool fibers and then to press them with the scattered layers 2, 3, 4.

Bei dem in Figur 6 gezeigten Ausführungsbeispiel besteht die Holzwerkstoffplatte 1a aus der mittleren Schicht 3a und der oberen Deckschicht 5a sowie der unteren Deckschicht 6a. Die Mittelschicht 3a besteht aus cellulosehaltigem Material, beispielsweise Holzspäne oder Holzfasern. Die Deckschichten 5a, 6a bestehen ebenfalls aus lignocellulosehaltigem Material. Zusätzlich sind hier aber auch noch Glasfasern bzw. Steinwollefasern in die Deckschichten 5a, 6a integriert und mit den Holzspänen oder Holzfasern verklebt bzw. verpresst.At the in FIG. 6 As shown, the wood-based panel 1a consists of the middle layer 3a and the upper cover layer 5a and the lower cover layer 6a. The middle layer 3a consists of cellulose-containing material, for example wood chips or wood fibers. The cover layers 5a, 6a also consist of lignocellulose-containing material. In addition, however, here are also glass fibers or rock wool fibers integrated into the cover layers 5a, 6a and glued or pressed with the wood chips or wood fibers.

Die Glasfasern bzw. Steinwollefasern müssen nicht in beiden Deckschichten 5a, 6a enthalten sein oder diese bilden, sondern sie können optional auch in einer der Deckschichten 5a oder 6a enthalten sein.The glass fibers or rockwool fibers need not be contained in or form two cover layers 5a, 6a, but may optionally also be contained in one of the cover layers 5a or 6a.

Die in Figuren 1 bis 3 hergestellte Holzwerkstoffplatte 1 kann eine übliche OSB-, Span-, Sperrholz- oder Faserplatte sein, auf die in einem zweiten Herstellungsschritt entweder die Glasfaser oder Steinwollefaserschicht aufgebracht oder ein Glasfaser-oder Steinwollefaservlies aufgelegt wird. Zur Verbindung können herkömmliche Klebstoffe verwendet werden, die auch zur Herstellung der Holzwerkstoffplatte an sich verwendet werden. Bevorzugt werden pulverförmige Klebstoffe wie sie für die Herstellung von Glasfaserdämmstoffen verwendet werden, beispielsweise Phenol-Formaldehyd-Resole oder Phenol-Formaldehyd-Novolake verwendet. Die Herstellung erfolgt zweckmäßigerweise in einer diskontinuierlichen Presse. Beispielsweise kann hierzu eine Kurztaktpresse Verwendung finden.In the FIGS. 1 to 3 produced wood-based panel 1 may be a conventional OSB, chipboard, plywood or fiberboard on which in a second manufacturing step, either the glass fiber or rock wool fiber layer applied or a fiberglass or rock wool fiber fleece is applied. For connection conventional adhesives can be used, which are also used for the production of the wood-based panel itself. Preference is given to using pulverulent adhesives of the kind used for the production of glass fiber insulating materials, for example phenol-formaldehyde resoles or phenol-formaldehyde novolaks. The preparation is advantageously carried out in a batch press. For example, a short-cycle press can be used for this purpose.

Es ist ebenso möglich, Glasfasern oder Steinwollefasern im üblichen kontinuierlichen oder diskontinuierlichen Produktionsprozess entweder sowohl in die Deckschichten 5a, 6a und die Mittelschicht 3a einzustreuen. Es kann aber auch eine zusätzliche Deckschicht gestreut werden. Auch hier können die bereits vorgenannten Klebstoffe verwendet werden. Diese müssen dann aber separat in einer Beleimungseinrichtung mit den Glasfasern bzw. Steinwollefasern vermengt (pulverförmige Klebstoffe) bzw. eingedüst (flüssige Klebstoffe) werden. Das Verpressen erfolgt dann mittels üblicher kontinuierlich arbeitender Pressen oder mit Etagen- bzw. Mehretagenpressen.It is also possible to scatter glass fibers or rockwool fibers in the usual continuous or discontinuous production process either in the cover layers 5a, 6a and the middle layer 3a. But it can also be scattered an additional cover layer. Again, the aforementioned adhesives can be used. These must then but separately in a gluing device with the glass fibers or rockwool fibers mixed (powdered adhesives) or injected (liquid adhesives) are. The pressing is then carried out by means of usual continuously working presses or with floor or multi-day presses.

Eine dritte Art der Herstellung ist schematisch in Figur 7 gezeigt. Hier werden Glasfaser- oder Steinwollevliese 5b, 6b während des Streuvorganges der Holzwerkstoffplatte abgerollt. Auf das endlos im Uhrzeigersinn umlaufende Transportband 7 wird zunächst ein Glasfaser- oder Steinwollefaservlies 6b von einem Abroller 10 abrollend aufgelegt. Dann werden einzelne Holzspäne-, Holzfaser- oder Strandsschichten 2b, 3b, 4b mittels der Streueinrichtung 8 gestreut, wobei die Orientierung der Späne bzw. Strands in benachbarten Schichten jeweils um 90° versetzt sein kann. Anschließend wird vom Abroller 9 ein oberes Glasfaser- oder Steinwollefaservlies 5b aufgelegt. Der so aufgebaute Kuchen wird anschließend in einer Presse 11 bei erhöhter Temperatur zu der Holzwerkstoffplatte gewünschten Dicke verpresst. Die Vliese 5b, 6b könne vor dem Verpressen mit handelsüblichen flüssigen Klebstoffen getränkt oder beleimt worden sein. Es können aber auch pulverförmige Klebstoffe eingearbeitet werden. Auch hier werden bevorzugt solche pulverförmigen Klebstoffe verwendet, wie sie für die Herstellung von Glasfaserdämpfstoffen verwendet werden, beispielsweise Phenol-Formaldehyd-Resole oder Phenol-Formaldehyd-Novolake. Das Aufkaschieren kann sowohl ein- als auch beidseitig erfolgen. Als herkömmliche Klebstoffe zur Herstellung werden MUPF- und/oder PMDI-Klebstoffe eingesetzt. Zur Verbesserung der Eigenschaften der Holzwerkstoffplatte können weitere Additive eingesetzt werden wie z. B. Brandschutzmittel oder Flammschutzmittel. VOC- und Formaldehydfänger, Fungizide und Mittel gegen Termitenbefall können ebenfalls eingesetzt werden. Dabei kann es sich um handelsübliche Präparate handeln.A third way of manufacturing is schematically in FIG. 7 shown. Here fiberglass or rockwool nonwovens 5b, 6b are unrolled during the scattering process of the wood-based panel. On the endlessly circulating in the clockwise conveyor belt 7, a fiberglass or rock wool fiber fleece 6b is first applied by rolling from a dispenser 10. Then individual wood chips, wood fiber or beach layers 2b, 3b, 4b are scattered by means of the scattering device 8, wherein the orientation of the chips or strands in adjacent layers can each be offset by 90 °. Subsequently, an upper glass fiber or rock wool fiber fleece 5b is placed by the dispenser 9. The cake thus constructed is then pressed in a press 11 at elevated temperature to the wood-based material board desired thickness. The webs 5b, 6b may have been soaked or glued prior to pressing with commercially available liquid adhesives. But it can also be incorporated powdered adhesives. Again, such powdery adhesives are preferably used as they are used for the production of glass fiber, such as phenol-formaldehyde resoles or phenol-formaldehyde novolacs. The lamination can be done either on one or both sides. As conventional adhesives for the production of MUPF and / or PMDI adhesives are used. To improve the properties of the wood-based panel further additives may be used such. As fire retardants or flame retardants. VOC and formaldehyde scavengers, fungicides and anti-termite agents may also be used. These may be commercial preparations.

Eine weitere Art der Herstellung einer erfindungsgemäßen Holzwerkstoffplatte kann erfolgen, in dem in einem ersten Schritt eine OSB-Platte hergestellt wird. Anschließend werden Steinwollefasern mit einem Phenol-Formaldehyd-Novolak vermengt, wobei die Zugabemenge etwa 10% bezogen auf die Steinwollefasern beträgt. Dann wird daraus mechanisch ein Vlies gebildet. Dieses Vlies wird in einem weiteren Schritt in einer diskontinuierlichen Presse (z. B. einer Kurztaktpresse) auf die OSB-Platte aufgepresst. Dabei verbindet sich der Novolak am Faservliesstoff mit der Holzoberfläche, so dass ein weitgehend homogener Faserverbundwerkstoff entsteht. Die Steinwollefaser ist chemisch mit dem Novolak gebunden. Im Gegensatz zu einem rein geklebten System, das sich durch eine diskrete Grenzschicht zwischen der OSB und dem Steinwollevlies auszeichnen würde.Another type of production of a wood-based panel according to the invention can take place in which in a first step an OSB board is produced. Subsequently, rock wool fibers are blended with a phenol-formaldehyde novolak, the addition amount is about 10% based on the rock wool fibers. Then a fleece is formed mechanically. In a further step, this nonwoven is pressed onto the OSB board in a discontinuous press (for example a short-cycle press). In the process, the novolak on the nonwoven fabric combines with the wood surface, resulting in a largely homogeneous fiber composite material. The rockwool fiber is chemically bound to the novolak. In contrast to a purely glued system, which would be characterized by a discrete boundary layer between the OSB and the rock wool fleece.

In einfacher Weise und unter Verwendung zumeist vorhandener Vorrichtungen kann somit eine neue Holzwerkstoffplatte hergestellt werden, die sich durch eine hohe mechanische Stabilität und eine erschwerte Entflammbarkeit der beschichteten Oberfläche auszeichnet. Von besonderer Bedeutung ist, dass die Rohdichte der OSB-Grundplatte übliche Werte und einen üblichen Verlauf aufweist.In a simple manner and using mostly existing devices thus a new wood-based panel can be produced, which is characterized by a high mechanical stability and a difficult flammability of the coated surface. Of particular importance is that the bulk density of the OSB baseplate has common values and a common course.
