Description

Die Erfindung betrifft eine Trägerplatte aus Bindemitteln und einem Holzwerkstoff gemäß dem Oberbegriff des Anspruchs 1 sowie ein Paneel mit einer solchen Trägerplatte.The invention relates to a carrier plate of binders and a wood material according to the preamble of claim 1 and a panel with such a carrier plate.

Eine solche Trägerplatte ist insbesondere für ein Fussbodenpaneel geeignet.Such a support plate is particularly suitable for a floor panel.

Als Trägerplatte im Laminatbodenbereich werden regelmäßig HDF-Platten mit einem spezifischen Gewicht von über 850 kg/m3 eingesetzt. Solch relativ schwere Trägerplatten erhöhen die Transportkosten und erschweren das Verlegen.HDF boards with a specific weight of more than 850 kg / m 3 are regularly used as a carrier board in the laminate floor area. Such relatively heavy carrier plates increase transport costs and make laying difficult.

Aus der DE 196 00 478 A1 ist ein Verfahren zur Herstellung einer leichten, mitteldichten Faserplatte bekannt, bei der die Faserplatte mit einer mittleren Rohdichte von weniger als 550 kg/m3 aus lignocellulosehaltigen Fasern und Polyurethanleim als Bindemittel hergestellt wird. Die Fasern werden dabei mit weniger als 4,0 Gew.-% Bindemittel bezogen auf atro Fasern vermischt.From DE 196 00 478 A1 a method for producing a lightweight, medium-density fiberboard is known in which the fiberboard is produced with a mean apparent density of less than 550 kg / m 3 of lignocellulose-containing fibers and Polyurethanleim as a binder. The fibers are mixed with less than 4.0 wt .-% binder based on atro fibers.

Aufgabe der Erfindung ist es, eine Trägerplatte aus Bindemitteln und Füllstoffen herzustellen, die einerseits leicht zu handhaben ist und andererseits eine ausreichende Festigkeit aufweist.The object of the invention is to produce a carrier plate of binders and fillers, which on the one hand is easy to handle and on the other hand has sufficient strength.

Erfindungsgemäß wird diese Aufgabe durch eine Trägerplatte mit den Merkmalen des Anspruchs 1 sowie ein Paneel mit den Merkmalen des Anspruchs 9 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.According to the invention this object is achieved by a support plate having the features of claim 1 and a panel having the features of claim 9. Advantageous embodiments and further developments of the invention are described in the subclaims.

Durch die Ausbildung der Trägerplatte mit einer Dichte von weniger als 700 kg/m3 bei gleichzeitigem Beleimungsfaktor größer als 10% wird erreicht, dass die Trägerplatte nahezu kunststoffähnliche Eigenschaften hinsichtlich Gewicht und Festigkeit aufweist, jedoch der Materialeinsatz aufgrund der eingebetteten Holzwerkstoffe, vorzugsweise Fasern, wesentlich geringer ist.Due to the design of the support plate with a density of less than 700 kg / m 3 with simultaneous Beleimungsfaktor greater than 10% is achieved that the support plate has almost plastic-like properties in terms of weight and strength, but the material use due to the embedded wood materials, preferably fibers, essential is lower.

Eine Weiterbildung sieht vor, dass die Trägerplatte eine Dichte zwischen 400 kg/m3 und 650 kg/m3 aufweist, wodurch eine optimale Festigkeit im Verhältnis zur Dichte und dem Materialeinsatz bewirkt wird.A further embodiment provides that the carrier plate has a density between 400 kg / m 3 and 650 kg / m 3 , whereby an optimal strength in relation to the density and the use of material is effected.

Vorteilhafterweise werden zur Beleimung der Holzwerkstoffe oder Fasern der Trägerplatte Harnstoffharze (UF-Harze) oder melaninverstärkte Harnstoffharze (MUF) eingesetzt. Darüber hinaus können Isozyanate als Beleimung der Faser in der Trägerplatte eingesetzt werden, wobei Isozyanate mit Beleimungsfaktoren von weniger als 20% vorgesehen sind. Isozyanate bieten aufgrund ihrer hohen Hitzebeständigkeit auch die Möglichkeit, höhere Beleimfaktoren zu realisieren. Ebenfalls wird durch die Zugabe von Isozyanaten die Festigkeit während einer hitzeintensiven Beschichtung der Trägerplatte aufrechterhalten, da bei ausschließlicher Verwendung von Harnstoffharzen die Tendenz besteht, dass die Trägerplatte während der Beschichtung einen Festigkeitsverlust erleidet.Advantageously, urea resins (UF resins) or melanin-reinforced urea resins (MUF) are used for gluing the wood materials or fibers of the support plate. In addition, isocyanates can be used as a gluing of the fiber in the support plate, wherein isocyanates with gluing factors of less than 20% are provided. Due to their high heat resistance, isocyanates also offer the possibility of achieving higher gluing factors. Also, by the addition of isocyanates, the strength is maintained during a heat-intensive coating of the backing plate, since the exclusive use of urea resins tends to cause the backing plate to lose strength during coating.

Zur angepassten Fertigung von Trägerplatten je nach Beanspruchung und Einsatzzweck ist es vorgesehen, dass eine Mischung aus Isozyanaten und UF- bzw. MUF-Harzen als Beleimung der Holzwerkstoffe oder Fasern und der Trägerplatte eingesetzt wird.For the customized production of carrier plates depending on the stress and intended use, it is provided that a mixture of isocyanates and UF or MUF resins is used as gluing of the wood materials or fibers and the carrier plate.

Eine Weiterbildung der Erfindung sieht vor, dass die Trägerplatte eine ungleichmäßige Dichteverteilung über den Querschnitt von der Oberseite zur Unterseite aufweist, wobei die an der Oberseite bzw. Unterseite befindlichen Deckschichten eine Dichte im Bereich von 1000 kg/m3 aufweisen, wohingegen die Mittelschichten im Querschnitt auf 400 kg/m3 - 600 kg/m3 verdichtet sind. Durch die hohe Verdichtung an den Ober- bzw. Unterseiten wird gewährleistet, dass eine hohe Widerstandsfähigkeit gegen vertikale, mechanische Beanspruchung erreicht wird, wie sie beispielsweise bei einer Verwendung für Fussbodenpaneele erforderlich ist. Ein Paneel mit einer solchen Trägerplatte ist auf der Oberseite und der Unterseite jeweils mit einer Abschlussschicht versehen, die üblicherweise aus einer melaningetränkten Dekorschicht oder Gegenzugschicht besteht, um die Trägerplatte zusätzlich vor mechanischen Schäden zu bewahren.A development of the invention provides that the carrier plate has a non-uniform density distribution over the cross section from the top to the bottom, wherein the cover layers located on the top or bottom have a density in the range of 1000 kg / m 3 , whereas the middle layers in cross section are compressed to 400 kg / m 3 - 600 kg / m 3 . The high density on the top and bottom sides ensures that a high level of resistance to vertical, mechanical stress is achieved, as is required, for example, when using floor panels. A panel with such a carrier plate is provided on the top and the bottom in each case with a finishing layer, which usually consists of a melaningetränkten decorative layer or Gegenzugschicht to additionally protect the carrier plate from mechanical damage.

Aufgrund der Gewichtsersparnis der spezifisch leichteren Trägerplatten werden die Transportkosten gesenkt und darüber hinaus wird eine bisher unbekannte Flexibilität der Trägerplatte realisiert, durch die besondere Profilausgestaltungen, insbesondere bei sogenannten Klickverbindungen, möglich sind.Due to the weight savings of specific lighter carrier plates transport costs are reduced and beyond a previously unknown flexibility of the support plate is realized by the special profile configurations, especially in so-called click connections, are possible.

Darüber hinaus führt die Erhöhung des Beleimungsfaktors zu einer verbesserten Feuchtigkeitsbeständigkeit, da durch den verringerten Holzwerkstoffanteil in den Platten die Neigung zum Aufquellen der Trägerplatte verringert wird. Üblicherweise führt das Eindringen von Nässe im Bereich der Verbindungsstellen zweier Trägerplatten bzw. zweier Fussbodenpaneelen zu einem Aufquellen der Trägerplatten in diesem Bereich und damit zu einer Zerstörung des Fussbodens. Die erfindungsgemäße Trägerplatte und ein damit hergestelltes Fussbodenpaneel eignet sich aufgrund der geringeren Quellneigung (unter 5 %) insbesondere für den Einsatz in Feuchträumen.In addition, the increase of the gluing factor leads to an improved moisture resistance, since the reduced proportion of wood material in the plates reduces the tendency for the carrier plate to swell. Usually, the penetration of moisture in the region of the connection points of two support plates or two floor panels leads to a swelling of the support plates in this area and thus to a destruction of the floor. The carrier plate according to the invention and a floor panel made therewith are suitable due to the lower swelling tendency (less than 5%), especially for use in damp rooms.

Darüber hinaus ist aufgrund der unterschiedlich verdichteten Schichten innerhalb der Trägerplatte eine Brechung der Schallwellen an den Dichteübergängen gegeben, so dass der Tritt- und Raumschall deutlich verringert wird.In addition, due to the differently densified layers within the carrier plate, there is a refraction of the sound waves at the density transitions, so that the impact and room sound is significantly reduced.

Nachfolgend wird die Erfindung anhand der beigefügten Figuren näher erläutert werden. Es zeigen:

Figur 1 -
ein Paneel in Querschnittsansicht; sowie
Figur 2 -
eine Dichteverteilung über den Querschnitt einer Trägerplatte.
The invention will be explained in more detail with reference to the accompanying figures. Show it:
FIG. 1 -
a panel in cross-sectional view; such as
FIG. 2 -
a density distribution over the cross section of a carrier plate.

Figur 1 zeigt im Querschnitt ein Fussbodenpaneel 10 mit einer Trägerplatte 1, auf deren Oberseite 15 und Unterseite 5 je eine Abschlußschicht 16, 6 aufgebracht ist. Die Abschlußschichten 16, 6 sind auf den den äußeren Abschluß der Trägerplatte 1 bildenden Deckschichten 7, 17 aufgebracht, vorzugsweise verleimt und schützen die Trägerplatte 1 beispielsweise gegen Feuchtigkeit und mechanische Belastungen. Ebenfalls können diese Abschlußschichten 6, 16 ein Dekor aufweisen und vergrößern die mechanische Stabilität des Fussbodenpaneels 10.Figure 1 shows in cross-section a floor panel 10 with a support plate 1, on whose top 15 and bottom 5 each have a final layer 16, 6 is applied. The final layers 16, 6 are applied to the outer end of the support plate 1 forming cover layers 7, 17, preferably glued and protect the support plate 1, for example, against moisture and mechanical stress. Likewise, these end layers 6, 16 may have a decor and increase the mechanical stability of the floor panel 10.

An den Seitenkanten des Paneels 10 sind Verriegelungsmittel 2, 3 ausgebildet, die eine Relativbewegung zweier miteinander verbundener Paneele sowohl in vertikaler Richtung V als ein in Querrichtung Q verhindern. Die Trägerplatte 1 ist dabei aus einem Fasermaterial hergestellt, das üblicherweise für die Herstellung von HDF-Platten verwendet wird, alternativ oder ergänzend werden andere Holzwerkstoffe eingearbeitet. Die Deckschichten 7, 17 der Trägerplatte 1 weisen im Gegensatz zu dem Kern 20 der Trägerplatte 1 eine wesentlich höhere Dichte auf, wobei Dichten bis zu 1000 kg/m3 in den Deckschichten 7, 17 erreicht werden. Innerhalb des Kernes 20 nimmt die Dichte kontinuierlich bis zur Mitte M der Trägerplatte 1 ab, wobei eine entsprechende Dichteverteilung über die Dicke d einer Trägerplatte 1 in der Figur 2 dargestellt ist. Darin ist zu erkennen, dass der geringste Wert für die Dichte ρ in der Mitte M der Trägerplatte erreicht wird, während sich über die Dicke d der Trägerplatte von der Mitte M ausgehend die Dichte ρ erhöht, um an den Oberflächen der Deckschichten 7, 17 ihr Maximum zu erreichen.On the side edges of the panel 10 locking means 2, 3 are formed which prevent a relative movement of two interconnected panels both in the vertical direction V as a transverse direction Q. The carrier plate 1 is made of a fiber material, which is usually used for the production of HDF boards, alternatively or additionally other wood materials are incorporated. In contrast to the core 20 of the carrier plate 1, the cover layers 7, 17 of the carrier plate 1 have a substantially higher density, with densities of up to 1000 kg / m 3 being achieved in the cover layers 7, 17. Within the core 20, the density continuously decreases to the center M of the carrier plate 1, wherein a corresponding density distribution over the thickness d of a carrier plate 1 in the figure 2 is shown. It can be seen that the lowest value for the density ρ in the center M of the carrier plate is achieved, while the thickness d of the carrier plate from the center M, starting from the Density ρ is increased in order to reach its maximum on the surfaces of the cover layers 7, 17.

Durch die extrem hohe Dichte in den Deckschichten 7, 17 im Bereich von 1000 kg/m3 wird der Trägerplatte 1 die notwendige Widerstandsfähigkeit gegen vertikale, mechanische Beanspruchungen verliehen, wobei in Kombination mit der Verwendung von UF- oder MUF-Harzen, gegebenenfalls in Mischung mit Isozyanaten, eine besondere Flexibilität innerhalb der Platte erzeugt werden kann. Die Zugabe von Isozyanaten verbessert die Feuchtigkeitsbeständigkeit der Trägerplatte 1, so dass die wesentlichen Eigenschaften der Trägerplatte 1 durch die eingesetzten Harze bzw. eingebrachten Kunststoffe festgelegt werden.Due to the extremely high density in the cover layers 7, 17 in the range of 1000 kg / m 3 , the support plate 1 is given the necessary resistance to vertical, mechanical stresses, in combination with the use of UF or MUF resins, optionally mixed with isocyanates, a special flexibility can be generated within the plate. The addition of isocyanates improves the moisture resistance of the carrier plate 1, so that the essential properties of the carrier plate 1 are determined by the resins used or introduced plastics.
