Abstract
Description
Die Erfindung betrifft eine Holzwerkstoffplatte mit mindestens drei Schichten aus einem Holzwerkstoff, deren mindestens eine mittlere Schicht aus einem Gemisch aus Holzwerkstoff und einem geschäumten Kunststoff besteht, sowie ein Verfahren zum Herstellen einer Holzwerkstoffplatte.The invention relates to a wood-based panel having at least three layers of a wood material whose at least one middle layer consists of a mixture of wood material and a foamed plastic, and to a method for producing a wood-based panel.
Eine solche Holzwerkstoffplatte ist beispielsweise aus der
Mit abnehmender Rohdichte der leichten Holzwerkstoffplatte sinken die mechanischtechnologischen Parameter, so dass derartige Platten nicht unter einer mittleren Rohdichte von 500 kg/m3 verwendet werden können.With decreasing bulk density of the lightweight wood-based panel, the mechanical technological parameters decrease, so that such panels can not be used at an average density of 500 kg / m 3 .
Unter Holzwerkstoffplatten versteht man plattenförmiges Sperrholz, Holzspanplatten, wie Flachpressplatten, Strangpressplatten, OSB-Platten oder Spantischlerplatten, Holzfaserplatten, wie z. B. MDF- oder HDF-Fasern sowie andere Holzwerkstoffplatten, wie Schichtholzplatten, Sichtholzformteile oder auch Pressschichtholz. Insbesondere bei Holzwerkstoffplatten in der Möbelindustrie stellt sich das Problem, dass stabile Platten aufgrund ihrer Dicke relativ schwer sind, was insbesondere für Selbstaufbauer zu Transportproblemen führen kann.Under wood-based panels are meant plate-shaped plywood, chipboard, such as flat-pressed, extruded, OSB or Spantischlerplatten, wood fiber boards, such. As MDF or HDF fibers and other wood-based panels, Like laminated wood panels, molded wood parts or laminated plywood. Especially with wood-based panels in the furniture industry, the problem arises that stable plates are relatively heavy due to their thickness, which can lead to transport problems especially for self-builders.

Dieses Vorprodukt wird in einer Presse verpresst, so dass das aufgeschäumte Harz in der Mittelschicht des Pressrohlings verbleibt. Anschließend wird der Pressrohling in einer Dampfpresse Hochtemperaturdampf ausgesetzt, so dass die aufgeschäumten Harzpartikel aushärten.This precursor is pressed in a press so that the foamed resin remains in the middle layer of the press blank. Subsequently, the press blank is exposed in a steam press high-temperature steam, so that the foamed resin particles cure.

Von dieser Problemstellung ausgehend soll die eingangs beschriebene Holzwerkstoffplatte dahingehend verbessert werden, dass bei einer weiteren Absenkung der Rohdichte gute mechanische/technische Parameter erhalten bleiben und die Emission von Aldehyden verringert wird.Starting from this problem, the wood-based panel described above is to be improved to the effect that good mechanical / technical parameters are maintained in a further reduction of the density the emission of aldehydes is reduced.
Zur Problemlösung zeichnet sich eine gattungsgemäße Holzwerkstoffplatte dadurch aus, dass die wenigstens eine mittlere Schicht zusätzlich mindestens einen geschäumten natürlichen Werkstoff aufweist.To solve the problem, a generic wood-based panel is characterized in that the at least one middle layer additionally has at least one foamed natural material.
Als natürlicher Werkstoff kommen beispielsweise Mais, Reis, Weizen oder eine Mischung hieraus in Frage. Der natürliche Werkstoff hat den Vorteil, dass er gegenüber herkömmlichen Werkstoffen eine höhere Festigkeit aufweist, dabei aber eine geringere Dichte als die Holzfasern oder Holzspäne besitzt. Damit kann eine mittlere Rohdichte von kleiner als 500 kg/m3 erzielt werden, wobei die Rohdichte der Deckschichten größer als 500 kg/m3 ist.As a natural material, for example, corn, rice, wheat or a mixture of these come into question. The natural material has the advantage that it has a higher strength compared to conventional materials, but it has a lower density than the wood fibers or wood chips. Thus, a mean apparent density of less than 500 kg / m 3 can be achieved, wherein the bulk density of the outer layers is greater than 500 kg / m 3 .
Vorzugsweise ist die Rohdichte der Mittelschicht kleiner als 450 kg/3 und die Abweichung der mittleren Rohdichte übersteigt plus/minus 50 kg/m3 nicht.Preferably, the bulk density of the middle layer is less than 450 kg / 3 and the deviation of the average bulk density does not exceed plus / minus 50 kg / m 3 .
Zur weiteren Verstärkung kann die mittlere Schicht faser- oder fadenförmige Bestandteile aufweisen. Diese Bestandteile bestehen vorzugsweise aus natürlichen Werkstoffen, insbesondere aus Flachs.For further reinforcement, the middle layer may have fibrous or filamentary components. These components are preferably made of natural materials, in particular flax.
Die faser- oder fadenförmigen Bestandteile können aber auch aus Kunststoff, insbesondere aus Karbon, PE, PP, PET, aus Glasfasern oder aus zwei Komponenten bestehen.The fibrous or filamentary components may also consist of plastic, in particular carbon, PE, PP, PET, glass fibers or two components.
Für die Deckschicht werden bevorzugt konventionelle Holzarten verwendet. Für die Mittelschicht werden bevorzugt Hölzer mit niedriger Rohdichte, wie z. B. Pappel oder Erle. Es können aber auch andere geeignete Holzarten verwendet werden.Conventional types of wood are preferably used for the cover layer. For the middle layer are preferably woods with low bulk density, such as. Poplar or alder. However, other suitable types of wood can be used.
Zumindest die mittlere Schicht kann zusätzliche Füllstoffe aus Kunststoff, vorzugsweise auf Basis von Polyurethanschäumen und/oder Polystyrolschäumen aufweisen.At least the middle layer may contain additional fillers of plastic, preferably based on polyurethane foams and / or polystyrene foams exhibit.
Zur Erhöhung der Wärmespeicherkapazität der Holzwerkstoffplatte kann die mittlere Schicht zusätzlich Latentwärmespeicher enthalten. Als Latentwärmespeicher können Kunststoffkapseln mit einem Kern aus reinem Wachs verwendet werden, wie sie beispielsweise von der BASF unter der Bezeichnung "Micronal PCM" vertrieben werden. Steigt die Raumtemperatur über die bei der Herstellung der mikroskopisch kleinen Kunststoffkapseln definierte Schalttemperatur von 23 oder 26 Grad Celsius an, verflüssigt sich das Wachs im Inneren der Mikrokapseln und absorbiert die überschüssige Raumwärme. Fällt die Temperatur hingegen ab, verfestigt sich das Wachs und die Kapseln geben ihre Wärme wieder an den Raum ab. Für die periodische Abfolge von Schmelzen und Erstarren sorgt die Natur durch die Temperaturunterschiede zwischen Tag und Nacht. Die Latentwärmespeicher tragen also so dazu bei, Temperaturspitzen am Tag abzufangen.To increase the heat storage capacity of the wood-based panel, the middle layer may additionally contain latent heat storage. As latent heat storage plastic capsules can be used with a core of pure wax, as sold for example by BASF under the name "Micronal PCM". If the room temperature rises above the switching temperature of 23 or 26 degrees Celsius defined during the production of the microscopically small plastic capsules, the wax liquefies inside the microcapsules and absorbs the surplus room heat. If the temperature drops, however, the wax solidifies and the capsules release their heat back to the room. For the periodic sequence of melting and solidification, nature provides the temperature differences between day and night. The latent heat storage thus contribute to catch temperature peaks during the day.
Die mit Klebstoff versehenen Holzfasern, Holzspäne oder Holzstrands werden mitsamt den Füllstoffen und der weiteren leichten Komponenten zu Schichten aufgestreut und anschließend in einem Heißpressverfahren miteinander unter Wirkung von Druck miteinander verbunden. Als Klebstoffe geeignet sind UF, MUF, MUPF, PF, TF, die alle optional einen Proteinanteil aufweisen können, wie beispielsweise pPF, Klebstoffe auf Basis von Soja, pMDI oder Mischungen aus den zuvor genannten Elementen.The provided with adhesive wood fibers, wood chips or wood strands are strewn together with the fillers and the other light components to layers and then connected together in a hot pressing process under pressure. Suitable adhesives are UF, MUF, MUPF, PF, TF, which may all optionally contain a proportion of protein, such as pPF, soy-based adhesives, pMDI or mixtures of the aforementioned elements.
Ein Verfahren zur Herstellung einer aus mindestens drei Schichten bestehenden Holzwerkstoffplatte, bei dem jede einzelne Schicht mit aus einem leimbenetzten Holzmaterial gestreut wird, zeichnete sich dadurch aus, dass der mindestens einen mittleren Schicht aufschäumbare Naturprodukte, insbesondere Mais, Reis oder Weizen zugegeben werden und die gestreuten Schichten zu einer Platte gewünschter Stärke verpresst werden, wobei die Naturprodukte während des Verpressens aufschäumen.A method for producing a wood-based panel consisting of at least three layers, in which each individual layer is sprinkled with a glue-wetted wood material, was characterized in that the at least one middle layer of foamable natural products, especially corn, rice or wheat are added and the scattered Layers are pressed to a plate desired thickness, wherein the natural products foam during compression.
Anstatt die Naturprodukte während des Heißpressens aufzuschäumen, können diese auch kurz vorher aufgeschäumt werden. Dasselbe gilt auch für die aufschäumenden Kunststoffe. Einige natürliche Bestandteile, wie beispielsweise Mais, schäumen einfach durch Hitze in der Presse auf. Andere, wie z. B. Weizen oder Reis, enthalten meist zu wenig Wasser, um in der Presse aufschäumen zu können, und müssen daher vor dem Einbringen in die mittlere Schicht aufgeschäumt werden.Instead of foaming the natural products during hot pressing, these can be frothed shortly before. The same applies to the foaming plastics. Some natural ingredients, such as corn, are simply foamed by heat in the press. Others, such as As wheat or rice, usually contain too little water to be able to foam in the press, and must therefore be foamed prior to introduction into the middle layer.
Vorzugsweise werden der wenigstens einen mittleren Schicht auch Füllstoffe aus Kunststoff auf Basis von Polyurethanschäumen oder Polystyrolschäumen beigemischt, die während des Verpressens zusätzlich zu den Naturprodukten aufschäumen.The at least one middle layer is preferably also admixed with plastic fillers based on polyurethane foams or polystyrene foams, which foam in addition to the natural products during the pressing.
Das Aufschäumen der Naturprodukte erfolgt durch Aufplatzen, wodurch die Hohlräume zwischen den Holzfasern oder Holzspänen aufgefüllt werden. Die geschäumten Naturprodukte wirken zusätzlich aldehydfangend. Besonders vorteilhaft ist es, dass diese Wirkung durch die fixe Einbindung in die Plattenmatrix lang anhaltend ist.The foaming of the natural products takes place by bursting, whereby the voids between the wood fibers or wood chips are filled. The foamed natural products additionally act as an aldehyde catcher. It is particularly advantageous that this effect is long-lasting due to the fixed integration into the plate matrix.
