Description

Die Erfindung betrifft eine Dämmstoffplatte aus einem Holzwerkstoff-Bindemittelfaser-Gemisch sowie ein Verfahren zur Herstellung einer Dämmstoffplatte.The invention relates to an insulation board made of a wood material-binder fiber mixture and a method for producing an insulation board.

Die Herstellung von Dämmstoffen aus Fasern, beispielsweise Holz-, Flachs-, Hanf-, oder Wollfasern oder dergleichen, ggf. unter Zugabe thermoplastischer Bindemittelfasern, ist bekannt. Die Herstellung dieser Dämmstoffe und Vliese erfolgt im Trockenverfahren beispielsweise mit aerodynamischen Vlieslegungsverfahren mit räumlicher Ausrichtung der Faser-Bindemittelfasermatrix in einer das Fasergut auflockernden und verteilenden Trommel und anschließender thermischer Verfestigung der Faser-Bindemittelfasermatrix in einem Heißluftdurchströmungstrockner. Dies ist beispielsweise in der DE 100 56 829 A1 beschrieben.The production of insulating materials from fibers, for example wood, flax, hemp or wool fibers or the like, optionally with the addition of thermoplastic binder fibers, is known. The production of these insulating materials and nonwovens takes place in a dry process, for example with aerodynamic nonwoven laying processes with spatial orientation of the fiber-binder fiber matrix in a fiber loosening and distributing the fiber and subsequent thermal solidification of the fiber-binder fiber matrix in a hot air flow dryer. This is for example in the DE 100 56 829 A1 described.

Bei Holzfaserdämmstoffen kann die Herstellung der Dämmstoffplatten auch im Nassverfahren mit einem anschließenden Warmpressverfahren erfolgen.In the case of wood-fiber insulating materials, the production of the insulating panels can also be carried out by wet process with a subsequent hot-pressing process.

Bei den bisherigen Verfahren zur Herstellung von Dämmstoffen aus natürlichen und synthetischen Fasern besteht häufig noch eine unzureichende räumliche Ausrichtung der Holz- und Bindemittelfasern, Aufgrund der überwiegend parallelen Ausrichtung der Fasern sind diese Dämmstoffplatten senkrecht zu den Oberflächen der Platten trotz der thermischen Verfestigung im Heißluftdurchströmungstrockner leicht spaltbar. Außerdem ist die Drucksteifigkeit dieser Dämmstoffplatten aufgrund der geringen Rohdichte relativ gering.In the previous process for the production of insulating materials from natural and synthetic fibers, there is often insufficient spatial alignment of the wood and binder fibers, Due to the predominantly parallel orientation of the fibers, these insulating panels are easily split perpendicular to the surfaces of the plates despite the thermal solidification in the hot air flow dryer , In addition, the compressive stiffness of these insulation boards is relatively low due to the low density.

Dies hat zur Folge, dass der Einsatz solcher Platten als Dämmstoff und Putzträger, insbesondere im Außenbereich, problematisch ist, da wenig drucksteife und wenig querzugfeste Dämmstoffe mit speziellen Befestigungsmitteln am Untergrund befestigt werden müssen. Außerdem wirkt sich eine zu geringe Drucksteifigkeit negativ auf die Schlagstoßfestigkeit des Wärmedämmverbundsystems aus.This has the consequence that the use of such plates as an insulating material and plaster base, especially in outdoor areas, is problematic, since little pressure-resistant and low tensile strength insulating materials must be fixed with special fasteners on the ground. In addition, a too low compressive stiffness has a negative impact on the impact resistance of the thermal insulation composite system.

Zur Erreichung einer ausreichenden Gefügefestigkeit der Dämmstoffplatte werden Bindemittelfasem eingesetzt, die in der Regel aus einem Polyester oder einem Polypropylenkern mit Dicken von 2,2 bis 4,4 Detex bestehen und mit einem Anteil von bis zu 25 Gewichtsprozent zugesetzt werden. Da die Kosten für diese Bindemittelfasem im Vergleich zu Holzfasern relativ hoch sind, sind solche Dämmstoffe vergleichsweise teuer. Weiterhin wirkt sich der Zusatz von Bindemittelfasern nur bedingt verbessernd auf die Erhöhung der Drucksteifigkeit aus. Eine optimale Rohdichte für eine Holzfaserplatte als Putzträgerplatte liegt bei ca. 100 kg/m3. Höhere Rohdichten wirken sich negativ auf die Wärmeleitfähigkeit der Dämmplatte dergestalt aus, dass die erforderliche Wärmeleitfähigkeitsgruppe WLG 040 nicht erreicht wird, andererseits wird eine erhöhte Stabilität erreicht.In order to achieve a sufficient structural strength of the insulating panel binder fibers are used, which are usually made of a polyester or a polypropylene core with thicknesses of 2.2 to 4.4 Detex and are added in a proportion of up to 25 weight percent. Since the costs for these binder fibers are relatively high compared to wood fibers, such insulation materials are comparatively expensive. Furthermore, the addition of binder fibers has only a limited effect on improving the compressive stiffness. An optimum density for a wood fiber board as a plaster base plate is about 100 kg / m 3 . Higher densities have a negative effect on the thermal conductivity of the insulation board in such a way that the required thermal conductivity group WLG 040 is not reached, on the other hand increased stability is achieved.

Aus der US-A 5,749,954 B1 ist eine Dämmstoffplatte aus Altpapierfasem und neuen Zellulosefasern bekannt, die Perlite-Granulate umgeben. Eine Bindung der Granulate mit den Fasern erfolgt über die Zugabe von Stärke, Bituminöses Material kann die Wasseraufnahmefähigkeit verringern und trägt zur Fixierung der Granulate in der Fasermatrix bei.From the US Pat. No. 5,749,954 B1 is an insulation board made of waste paper fibers and new cellulose fibers known to surround perlite granules. Binding of the granules to the fibers takes place via the addition of starch. Bituminous material can reduce the water absorption capacity and contributes to the fixation of the granules in the fiber matrix.

Aufgabe der vorliegenden Erfindung ist es, eine Dämmstoffplatte, ein Additiv für eine Dämmstoffplatte sowie ein Verfahren zur Herstellung einer Dämmstoffplatte bereitzustellen, mit dem die Drucksteifigkeit und Gefügefestigkeit von Dämmstoffplatten aus Holzwerkstoffen, insbesondere Holzfasern, mit geringen Rohdichten kostengünstig erhöht werden kann.Object of the present invention is to provide an insulation board, an additive for an insulation board and a method for producing an insulation board, with which the compressive rigidity and structural strength of insulation boards of wood materials, especially wood fibers, can be increased inexpensively with low densities.

Erfindungsgemäß wird diese Aufgabe durch eine Dämmstoffplatte aus einem Holzwerkstoff-Bindemittelfaser-Gemisch gelöst, bei der dem Gemisch ein Additiv aus einem thermisch beständigen Kern zugegeben wird, wobei der Kern mit einer thermisch aktivierbaren Beschichtung versehen ist.According to the invention, this object is achieved by an insulating board made of a wood-material-binder fiber mixture, in which the mixture is added to an additive of a thermally stable core, wherein the core is provided with a thermally activatable coating.

Vorteilhafter Weise besteht der Kern aus Perlite oder einem Duroplastwerkstoff, was aufgrund der hydrophoben Eigenschaften des Additivs eine Verbesserung der Feuchtebeständigkeit der Dämmstoffplatte zufolge hat. Dies ergibt sich aus einer entsprechend der Zugabe des Additivs verringerten Masse an hydrophilen Holzwerkstoffen, insbesondere Holzfasern.Advantageously, the core consists of perlite or a thermoset material, which has an improvement in the moisture resistance of the insulation board due to the hydrophobic properties of the additive. This results from a reduced mass of hydrophilic wood materials, in particular wood fibers, corresponding to the addition of the additive.

Darüber hinaus ist vorgesehen, dass der Kern als ein Granulat oder als Faserwerkstoff ausgebildet ist, um mit möglichst vielen Holzwerkstoff-Komponenten oder Holzfasern sowie Bindemittelfasern in Kontakt zu treten.In addition, it is provided that the core is formed as a granulate or as a fiber material in order to come into contact with as many wood material components or wood fibers as possible as well as binder fibers.

Zur Steigerung der Druckfestigkeit und Querzugsfestigkeit werden dem trockenen Holzfaser-Bindemittelfasergemisch ein feinkörniges Granulat oder feinkörnige Partikel aus bituminiertem Perlite, aus verschiedenen Thermoplastgruppen, thermoplastisch ummantelten Duroplastgruppen oder vergleichbaren Partikeln mit einem thermisch beständigen Kern und einem thermisch aktivierbaren oder thermoplastischen Mantel zugegeben. Die Korngrößen des Additivs betragen dabei zwischen 0,3 und 2,5 mm.To increase the compressive strength and transverse tensile strength, fine-grained granules or fine particles of bituminized perlite, of different thermoplastic groups, thermoplastically coated thermoset groups or comparable particles with a thermally stable core and a thermally activatable or thermoplastic shell are added to the dry wood fiber / binder mixture. The particle sizes of the additive are between 0.3 and 2.5 mm.

Zur Steigerung der Druck- und Gefügefestigkeit beträgt der Anteil des Additivs bezogen auf die Gesamtmasse des Holzwerkstoffes-Bindemittelfasergemisches mindestens 20 %, kann aber auch 40 % oder mehr betragen.To increase the compressive and structural strength, the proportion of the additive based on the total mass of the wood-material-binder fiber mixture is at least 20%, but may also be 40% or more.

Vorteilhafter Weise ist das Additiv homogen innerhalb des Holzwerkstoff-Bindemittelfasergemisches verteilt, um eine gleichmäßige Druck- und Gefügefestigkeit der Dämmstoffplatte zu gewährleisten.Advantageously, the additive is homogeneously distributed within the wood material-binder fiber mixture in order to ensure a uniform pressure and structural strength of the insulation board.

Im Gegensatz zu den hydrophilen Holzwerkstoffen ist es vorgesehen, dass das Additiv hydrophob ist, damit zusätzlich zu der verbesserten Drucksteifigkeit eine höhere Feuchtebeständigkeit der Dämmstoffplatte erzielt wird.In contrast to the hydrophilic wooden materials, it is provided that the additive is hydrophobic, so that in addition to the improved compressive rigidity, a higher moisture resistance of the insulation board is achieved.

Die Dämmstoffplatte hat vorzugsweise eine Rohdichte von mehr als 20 kg/m3, kann jedoch auch eine Rohdichte von über 100 kg/m3 aufweisen, um einerseits eine optimale Festigkeit und andererseits eine optimale Wärmeleitfähigkeit zu haben, so dass bei Verwendung als stabiler Putzträger eine gute Isolierung gewährleistet ist.The insulation board preferably has a bulk density of more than 20 kg / m 3 , but may also have a bulk density of over 100 kg / m 3 , on the one hand to have optimum strength and on the other hand optimum thermal conductivity, so that when used as a stable plaster base a good insulation is guaranteed.

Durch den Einsatz des Additivs kann der Anteil der Bindemittelfasem auf ca. 10 Gewichtsprozent, bezogen auf die Gesamtmasse der Dämmstoffplatte, reduziert werden, was die Kosten für die Dämmstoffplatte reduziert.Through the use of the additive, the proportion of binder fibers can be reduced to about 10 percent by weight, based on the total mass of the insulation board, which reduces the cost of the insulation board.

Ein Additiv zur Verbesserung der Drucksteifigkeit und Gefügeverbesserung von Dämmstoffplatten aus einem Holzwerkstoff-Bindemittelfaser-Gemisch sieht einen thermisch beständigen Kern und eine thermisch aktivierbare Beschichtung vor, so dass durch Energiezufuhr sowohl die Holzwerkstoffe als auch die Bindemittelfasern mit dem Additiv verbunden werden können. Die Wärmezufuhr erfolgt beispielsweise durch einen Heißluftdurchströmungstrockner, eine Heißdampfdurchströmung oder eine HF-Erwärmung. Andere Erwärmungsmöglichkeiten sind ebenfalls vorgesehen, beispielsweise durch beheizte Pressplatten. Die thermisch aktivierbare Beschichtung ist ein Thermoplast, um eine Vernetzung der Holzwerkstoffe und Bindemittelfasern mit dem Additiv zu bewirken.An additive to improve the compressive stiffness and microstructure improvement of insulation boards from a wood material-binder fiber mixture provides a thermally stable core and a thermally activatable coating, so that by energy supply both the wood materials and the binder fibers can be connected to the additive. The heat is supplied for example by a Heißluftdurchströmungstrockner, a superheated steam or HF heating. Other heating options are also provided, for example by heated press plates. The thermally activatable coating is a thermoplastic to effect cross-linking of the wood materials and binder fibers with the additive.

Die Beschichtung kann den Kern vollständig umschließen, alternativ ist nur eine teilweise Beschichtung der Oberfläche des Kernes vorgesehen.The coating may completely enclose the core, alternatively, only a partial coating of the surface of the core is provided.

Der Kern besteht aus einem Granulat, beispielsweise aus Perlite oder einem anderen mineralischen Grundstoff oder einer Faser, wobei alternativ zu einem mineralischen Werkstoff der Kern auch aus einem Duroplast bestehen kann. Ebenfalls ist es möglich, in Abstimmung mit der Prozessführung einen Thermoplast einzusetzen, der bei den vorhandenen Temperaturen formbeständig bleibt.The core consists of a granulate, for example of perlite or another mineral raw material or a fiber, alternatively to a mineral Material of the core can also consist of a thermosetting plastic. It is also possible, in coordination with the process control, to use a thermoplastic which remains dimensionally stable at the existing temperatures.

Vorteilhafterweise kann das Additiv ein Mischkunststoff sein, der neben duroplastischen auch thermoplastische Anteile aufweist. Derartige Mischkunststoffe sind beispielsweise Produkte des Dualen Systems (DS) mit durchschnittlichen Anteilen von 50 bis 70% Polyolefinen, 15 bis 20% Polystyrolen, 5 bis 15% PET und 1 bis 5% sonstigen Verpackungskunststoffen. Solche Mischkunststoffe werden in Trockenaufbereitungsverfahren hergestellt, wobei insbesondere gemischte Kunststoffe aus dem Hausmüll verwendet werden. Das Ausgangsmaterial wird in einer Zerkleinerungsstufe zunächst zerkleinert, magnetische Stoffe werden aus dem zerkleinerten Material entfernt und das zerkleinerte Material wird thermisch agglomeriert oder unter Druck kompaktiert, also pressagglomeriert. Während des Agglomeriervorgangs können flüchtige Stoffe, Wasserdampf, Asche und Papier durch Absaugvorrichtungen abgesaugt werden.Advantageously, the additive may be a mixed plastic, which in addition to thermosetting and thermoplastic shares. Such mixed plastics are, for example, products of the dual system (DS) with average proportions of 50 to 70% polyolefins, 15 to 20% polystyrenes, 5 to 15% PET and 1 to 5% other packaging plastics. Such mixed plastics are produced in dry treatment processes, in particular mixed plastics from household waste are used. The starting material is first comminuted in a comminution stage, magnetic substances are removed from the comminuted material, and the comminuted material is thermally agglomerated or compacted under pressure, ie, press-agglomerated. During the agglomeration process, volatiles, water vapor, ash and paper can be sucked through suction devices.

Das agglomerierte Material wird anschließend auf eine gewünschte Restfeuchte getrocknet und gesiebt. Durch den Agglomeratorprozess werden thermoplastische Kunststoffbestandteile, z.B. Polyethylen (LDPE, HDPE) und duroplastische Kunststoffbestandteile, z.B. Polyester oder Polyurethane, zu einem granulatartigen Material verbunden. Hierbei wird ein duroplastischer Kern aus beispielsweise Polyurethan ganz oder teilweise von einer thermisch aktivierbaren, thermoplastischen Hülle aus beispielsweise Polyethylen umgeben oder ein bei hohen Temperaturen schmelzender thermoplastischer Kern wird von einer bei niedrigen Temperaturen schmelzenden Hülle umgeben.The agglomerated material is then dried to a desired residual moisture and sieved. By the agglomerating process, thermoplastic plastic components, e.g. Polyethylene (LDPE, HDPE) and duroplastic plastic components, e.g. Polyester or polyurethane, connected to a granular material. In this case, a thermoset core of, for example, polyurethane is completely or partially surrounded by a thermally activatable, thermoplastic shell of, for example, polyethylene, or a thermoplastic core which melts at high temperatures is surrounded by a shell which melts at low temperatures.

Derart agglomerierte Mischkunststoffe weisen einen ausreichend hohen Anteil thermisch aktivierbarer (thermoplastischer) Anteile und duroplastischer Bestandteile auf und eignen sich aus diesem Grund besonders gut als Additiv zur Verbesserung der Drucksteifigkeit und Gefügeverbesserung und/oder als Bindemittel für eine Dämmstoffplatte, da die thermoplastische Hülle des Additivs durch eine ausreichende Temperaturzuführung beispielsweise bei einem Heißpressvorgang thermisch aktivierbar ist. Vorteilhafterweise lassen sich solcherart agglomerierte Mischkunststoffe bei Dämmstoffproduktionen zu Holzwerkstofffasern und bekannten Bindemittelfasern hinzugeben, da die agglomerierten Mischkunststoffe thermisch aktivierbare Bestandteile aufweisen, die zur Herstellung von Dämmstoffplatten unter Druck und Temperatur aktiviert werden, wobei die duroplastischen Kerne oder die thermoplastischen Kerne stabil bleiben. Dazu ist die Presstemperatur so einzustellen, dass sie immer kleiner ist als die Schmelztemperatur bzw. die Zersetzungstemperatur der Kernmaterialien.Such agglomerated mixed plastics have a sufficiently high proportion of thermally activatable (thermoplastic) shares and thermosetting constituents and are particularly suitable for this reason as an additive for improving the compressive stiffness and structural improvement and / or as a binder for an insulation board, since the thermoplastic shell of the additive a sufficient temperature supply For example, is thermally activated in a hot pressing process. Advantageously, mixed agglomerated plastics of this kind can be added to wood pulp fibers and known binder fibers in insulation product production, since the agglomerated mixed plastics have thermally activatable constituents which are activated under pressure and temperature for the production of insulating boards, the duroplastic cores or the thermoplastic cores remaining stable. For this purpose, the pressing temperature is set so that it is always smaller than the melting temperature or the decomposition temperature of the core materials.

Durch die Zugabe von agglomerierten Mischkunststoff zur Produktion der Dämpfstoffplatten lassen sich verbesserte Drucksteifigkeits- und Querzugsfestigkeitswerte der Platten erzielen, ohne den Anteil teurer Bindemittelfasern (mit Polypropylenkern und Polyethylenhülle) erhöhen zu müssen. Vorteilhafterweise ist die Erhöhung der Festigkeitseigenschaften ausschließlich durch Beigabe kostengünstiger, agglomerierter Mischkunststoffe möglich, die dem Dualen System entstammen.Through the addition of agglomerated mixed plastic for the production of the baffles, improved compression stiffness and transverse tensile strength values of the panels can be achieved without having to increase the proportion of expensive binder fibers (with polypropylene core and polyethylene shell). Advantageously, the increase in the strength properties is possible only by adding inexpensive, agglomerated mixed plastics, which originate from the dual system.

Das Additiv ist hydrophob, um die Feuchtebeständigkeit zu verbessern.The additive is hydrophobic to improve moisture resistance.

Das Verfahren zur Herstellung einer Dämmstoffplatte mit einem Holzwerkstoff-Bindemittelfasergemisch sieht vor, dass dem Gemisch ein Additiv mit einem thermisch beständigen Kern und einer thermisch aktivierbaren Beschichtung zugegeben wird. Die thermisch aktivierbare Beschichtung wird unter Wärmezufuhr aktiviert, so dass das Holzwerkstoff-Bindemittelfaser-Gemisch und das Additiv miteinander vernetzt werden. Dadurch wird eine Dämmstoffplatte bereitgestellt, die im optimalen Rohdichtebereich von ungefähr 100 kg/m3 angesiedelt ist und dabei eine ausreichende Druckfestigkeit und Querzugfestigkeit bei gleichzeitiger Feuchtebeständigkeit aufweist.The method for producing an insulation board with a wood-material-binder fiber mixture provides that the mixture is an additive with a thermally stable core and a thermally activatable coating is added. The thermally activatable coating is activated with the addition of heat, so that the wood material-binder fiber mixture and the additive are crosslinked with each other. As a result, an insulation board is provided which is located in the optimum density range of about 100 kg / m 3 and thereby has sufficient compressive strength and transverse tensile strength while moisture resistance.

Zur gleichmäßigen Durchmischung der Holzwerkstoffe und der Bindemittelfasern werden diese in einer aerodynamischen Vliesbildungsmaschine gemischt, anschließend wird das Additiv in einer separaten Vliesbildungsmaschine zugemischt. Dabei wird auch die räumliche Ausrichtung der Fasermatrix vorgenommen, wobei dies in einer gesonderten aerodynamischen Vliesbildungsmaschine erfolgt.For uniform mixing of the wood materials and the binder fibers, these are mixed in an aerodynamic web-forming machine, then the additive is mixed in a separate web-forming machine. there The spatial orientation of the fiber matrix is also carried out, this being done in a separate aerodynamic web-forming machine.

Die Beschichtung des Kernes wird dabei in einem Heißluftstrom aktiviert, alternative Aktivierungsmethoden, beispielsweise durch beheizte Walzen, HF-Erwärmung oder Infrarotstrahler sind ebenfalls möglich.
Eine gleichmäßige Ausbildung der Struktur der Dämmstoffplatte erfolgt durch eine homogene Verteilung des Additivs innerhalb des Holzwerkstoff-Bindemittelfasergemisches.The coating of the core is activated in a hot air stream, alternative activation methods, for example by heated rollers, RF heating or infrared radiators are also possible.
A uniform formation of the structure of the insulation board is effected by a homogeneous distribution of the additive within the wood-material binder fiber mixture.

Nachfolgend wird anhand der einzigen Figur die Erfindung näher erläutert.The invention will be explained in more detail with reference to the single figure.

Die Figur zeigt die Einbettung eines Additivs in eine Holzfaser-Bindemlttelfasermatrix.The figure shows the embedding of an additive in a wood fiber binder fiber matrix.

In der Figur ist eine Mischung aus Holzfasern 1 und Bindemittelfasern 2 dargestellt, die in einer ersten aerodynamischen Vliesbildungsmaschine homogen vermischt werden. Alternativ zu Holzfasern 1 können andere Holzwerkstoffe, beispielsweise Holzspäne oder dergleichen, eingesetzt werden, beispielsweise auch alternative Rohstoffe wie Hanf, Wolle, Flachs oder andere nachwachsende Rohstoffe.In the figure, a mixture of wood fibers 1 and binder fibers 2 is shown, which are homogeneously mixed in a first aerodynamic web forming machine. As an alternative to wood fibers 1 other wood materials, such as wood chips or the like, can be used, for example, alternative raw materials such as hemp, wool, flax or other renewable resources.

Anschließend erfolgt eine Zumischung eines vergütenden Additivs, das aus einem Kern 4 mit einer thermisch aktivierbaren Beschichtung 3 besteht. Diese thermisch aktivierbare Beschichtung 3 kann beispielsweise aus einem thermoplastischen Material bestehen. Diese Beschichtung 3 kann den Kern 4 entweder vollständig umgeben oder nur teilweise an dessen Oberfläche angeordnet sein.Subsequently, an admixing of a tempering additive, which consists of a core 4 with a thermally activatable coating 3, takes place. This thermally activatable coating 3 may for example consist of a thermoplastic material. This coating 3 can either completely surround the core 4 or be arranged only partially on its surface.

Das Additiv 3, 4 wird dem trockenen Gemisch aus Holzfasern 1 und Bindemittelfasern 2 als ein feinkörniges Granulat oder als Partikel aus entsprechenden Materialien, wie beschichteten Thermoplastgruppen oder thermoplastisch ummantelten Duroplastgruppen zugegeben. Die Korngrößen des Additivs 3, 4 sollten für diesen Einsatzzweck 0,3 - 2,5 mm, vorzugsweise 0,5 - 2 mm betragen. Zur Steigerung der Druck- bzw. Gefügefestigkeit sollte der Anteil des Additivs an der Gesamtmasse der Dämmplatte mindestens 20 % betragen, jedoch sind auch Werte von über 40 % möglich.The additive 3, 4 is added to the dry mixture of wood fibers 1 and binder fibers 2 as a fine-grained granules or as particles of corresponding materials, such as coated thermoplastic groups or thermoplastic-coated thermosets. The grain sizes of the additive 3, 4 should be 0.3 to 2.5 mm, preferably 0.5 to 2 mm for this purpose. To increase the pressure or structural strength, the proportion of the additive in the total mass of the insulating board should be at least 20%, but also values of over 40% are possible.

Die Zumischung des Additivs 3, 4 und die räumliche Ausrichtung der Fasermatrix erfolgt nach der Durchmischung der Holzfasern 1 und Bindemittelfasern 2 in einer separaten, zweiten aerodynamischen Vliesbildungsmaschine. Durch die Zugabe des Additivs 3, 4 mit der zusätzlichen verbindenden Wirkung der thermisch aktivierbaren Beschichtung 3 kann der Anteil an Bindemittelfasem 2 auf 10 % am Gesamtgewicht gesenkt werden.The admixture of the additive 3, 4 and the spatial orientation of the fiber matrix takes place after the mixing of the wood fibers 1 and binder fibers 2 in a separate, second aerodynamic web-forming machine. By adding the additive 3, 4 with the additional binding effect of the thermally activatable coating 3, the proportion of binder fibers 2 can be reduced to 10% of the total weight.

Mittels des aerodynamischen Vlies- bzw. Faserlegungsverfahrens mit räumlicher Ausrichtung werden die Partikel des Additivs 3, 4 homogen innerhalb der Matrix der Holz- und Bindemittelfasem 1, 2 verteilt. Die Aktivierung erfolgt vorteilhafter Weise in einem Heißluftdurchströmungstrockner, so dass durch die zugeführte Wärme der thermoplastische Mantel 3 des Kerns 4 der Additivpartikel zusätzliche Kontaktstellen zu den Holzfasern 1 und zu den Bindemittelfasern 2 ausbilden. Dadurch wird eine drucksteife Faser-Bindemittel-Additivmatrix mit verbesserter Gefügefestigkeit bereitgestellt.By means of the aerodynamic nonwoven or fiber-laying method with spatial orientation, the particles of the additive 3, 4 are homogeneously distributed within the matrix of the wood and binder fibers 1, 2. The activation takes place advantageously in a hot air flow dryer, so that form by the heat supplied, the thermoplastic shell 3 of the core 4 of the additive particles additional contact points to the wood fibers 1 and the binder fibers 2. This provides a pressure-stiff fiber-binder additive matrix having improved structural strength.

Die mit dem Additiv 3, 4 vergüteten Dämmstoffe können als Wärmedämmstoff im Außenbereich, z. B. für Wärmedämmverbundsysteme und als Trittschalldämmstoffe im Fußbodenbereich, z. B. unter Laminat- oder Fertigparkettböden eingesetzt werden.The tempered with the additive 3, 4 insulating materials can be used as a thermal insulation in the outdoor area, eg. B. for thermal insulation systems and as impact sound insulation in the floor area, z. B. be used under laminate or engineered parquet floors.
