Description
Verfahren zum Herstellen von Verbundplatten sowie derartige Verbundplatten Die Erfindung betrifft ein Verfahren zur Herstellung von Verbund platten mit einem Kern oder einer Beschichtung aus Faserlamellenplatten, bei denen die Fasern im wesentlichen senkrecht auf der Deckschicht stehen oder eine im wesentlichen senkrechte Verbindung zwischen zwei Deckschichten darstellen, sowie derartige Verbundplatten. Process for the production of composite panels and composite panels of this type The invention relates to a method for producing composite panels with a Core or a coating of fiber lamellar panels, in which the fibers are essentially stand perpendicular to the top layer or a substantially perpendicular connection represent between two cover layers, as well as composite panels of this type.
Es ist bekannt, verhältnismäßig druckfeste und biegesteife Bauplatten dadurch herzustellen, daß zwei aus beliebigem Material bestehende Deckschichten, wie z.B. Gipskarton, Asbestzement, Holzspan, Eunstharzlaminat, Metallblech oder auch Glas, mit einem Kern aus Mineralfaser verbunden sind, dessen Fasern quer zu den Deckschichten verlaufen. Dadurch wird ein sehr guter Verbund in solchen Systemen erreicht.It is known that building panels are relatively pressure-resistant and rigid to produce by having two cover layers made of any material, such as plasterboard, asbestos cement, wood chip, synthetic resin laminate, sheet metal or also glass, connected to a core of mineral fiber, the fibers of which are transverse to the top layers run. This creates a very good network in such systems achieved.
Ebenso ist es bekannt, Platten oder Tafeln der gleichen Art einseitig mit einer Isolierschicht aus solcher Mineralfaser mit einer Faserrichtung senkrecht zur Platte zu versehen, um beispielsweise die Druckbelastungsfähigkeit der Platte einschließlich der Isolierschicht wesentlich zu erhöhen.It is also known to use panels or panels of the same type on one side with an insulating layer of such mineral fiber with a fiber direction perpendicular to the plate, for example, the compressive strength of the plate including the insulating layer to increase significantly.
Man nennt solche Mineralfaserplatten mit einer im wesentlichen senkrecht zur Oberfläche verlaufenden Faser Lamellenplatten.One calls such mineral fiber boards with an essentially vertical Fiber lamellar panels running to the surface.
Nun ist es aber ein Problem, solche Faserlamellen in absolut gleicher Dicke herzustellen. Diese Lamellen werden nämlich dadurch hergestellt, daß normale Mineralfaserplatten mit parallel zur Oberfläche- verlaufender Faserrichtung in Streifen geschnitten werden und diese Streifen um 900 gedreht und wieder zusammengefügt werden.But now it is a problem, such fiber lamellas in absolutely the same way To manufacture thickness. These lamellas are made by the fact that normal Mineral fiber boards with fibers running parallel to the surface in strips are cut and these strips are rotated 900 and put back together.
Zum Schneiden dieser Lamellen sind vielfach technische Vorschläge gemacht worden, die aber alle den Nachteil haben, daß sie die Platten, aus denen die Fasern geschnitten werden, mehr oder weniger einspannen müssen, um die Schneidvorrichtung durch das Material zu führen. Das bedeutet aber immer ein Zusammendrücken der Faserplatte, da diese Platten aus einem sehr weichen Material bestehen. Nach dem Schneiden expandieren die Platten auf ihr ursprüngliches Maß, wodurch auch in der Querrichtung gewisse Längenänderungen auftreten können. Man hat versucht, diesem Ubelstand abzuhelfen, indem man die Lamellen nicht einzeln schneidet, sondern von einem Paket von Platten einen Satz Lamellen abschneidet. Jedoch eine Pressung im Bereich der Randzonen ist damit immer noch nicht vermieden. Die aus dieser Situation des Standes der Technik gewonnene Erkenntnis zeigt eindeutig, daß es nicht möglich ist, Lamellenstreifen von ausreichender Genauigkeit herzustellen, um eine vollflächige Verklebung der Deckschichten mit der Lamellenplatte sicherzustellen. Man ist daher gezwungen, eine größere Menge Klebstoff oder Haftmittel zu verwenden, als es für den eigentlichen technischen Zweck erforderlich wäre. Ein weiterer Punkt, der zu einem erhöhten Klebstoffverbrauch führt, ist die Struktur der Lamellenplatte an sich. In der Lamellenplatte stehen die masern im Wesentlichen senkrecht auf der Deckschicht. Um aber eine sichere Verbindung der senkrechten Faser mit der Deckschicht sicherzustellen, muß diese Faser ein wenig in den Klebstoff eintauchen.There are often technical proposals for cutting these lamellas have been made, but all have the disadvantage that they are the plates from which The fibers to be cut need to be more or less clamped to the cutting device guide through the material. But that always means compressing the fiberboard, because these plates are made of a very soft material. Expand after cutting the panels to their original dimensions, which also gives a certain degree in the transverse direction Changes in length can occur. Attempts have been made to remedy this evil by cutting the lamellas not individually, but from a package of sheets cut off a set of lamellas. However, there is pressure in the area of the edge zones thus still not avoided. The from this situation of the prior art The knowledge gained clearly shows that it is not possible to use lamellar strips of sufficient accuracy to ensure full-surface bonding of the Ensure top layers with the lamellar plate. One is therefore forced to have a Use larger amount of glue or adhesive than you would normally use technical Purpose would be required. Another point to be leads to an increased consumption of adhesive, the structure of the lamellar plate is on themselves. In the lamellar plate, the grains are essentially perpendicular to the Top layer. But to ensure a secure connection between the vertical fiber and the top layer to ensure this fiber has to be dipped a little into the adhesive.
Das erfordert aber wiederum eine dickere Klebstoffschicht, als für die Verklebung von parallel zur Deckschicht verlaufenden Fasern oder von ebenen Flächen aufeinander. In den letztgenannten Fällen können Klbstoffmengen von weniger als 100 g/qm bereits einen ausreichenden Klebeeffekt bewirken, währen be senkrecht stehenden Fasern eine Klebstoffmenge von mehr als 500 g/qm erforderlich ist, wobei noch vorausgesetzt werden muß, daß die Lamellen selber auf eine sehr gleichmäßige Dicke geschnitten sind. Da das aber wie oben dargelegt nicht möglich ist, steigt der Klebstoffbedarf noch weiter an.But that in turn requires a thicker layer of adhesive than for the bonding of fibers running parallel to the top layer or of flat fibers Surfaces on top of each other. In the latter cases, adhesive quantities of less can be used than 100 g / sqm already cause a sufficient adhesive effect, while be vertical standing fibers an amount of adhesive of more than 500 g / m² is required, whereby It must still be assumed that the lamellae themselves are very uniform Thickness are cut. But since this is not possible, as explained above, increases the need for adhesives continues to increase.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Verbundplatte der eingangs genannten Art zu schaffen, durch das oder durch die die vorstehend geschilderten Nachteile vermieden werden und insbesondere möglichst wenig Bindemittel eingesetzt werden muß, wobei aber gleichzeitig eine gute und vollständige Verbindung sichergestellt ist.The invention is based on the object of a method and a composite panel of the type mentioned to create, by or by the above The disadvantages outlined are avoided and, in particular, as little binder as possible must be used, but at the same time a good and complete connection is ensured.
Diese Aufgabe wird dadurch gelöst, daß das Bindemittel zwischen Faserschicht und Deckschicht aufgeschäumt wird.This object is achieved in that the binder between the fiber layer and top layer is foamed.
Es hat sich nämlich ganz überraschend herausgestellt, daß man den Klebstoffbedarf ganz erheblich senken kann und dabei sogar noch einen wesentlich besseren Verbund zwischen Deckschichten und Faserkern aus Iamellenplatten herstellen kann, wenn der Klebstoff in Form einer aufgeschäumten Schicht verwendet wird.It turned out, quite surprisingly, that one can use the Can reduce the need for adhesives quite considerably and at the same time significantly Create a better bond between the outer layers and the fiber core from lamellar panels when the adhesive is used in the form of a foamed layer.
Der Schaum tritt dann in die Lamellenplatte ein und sorgt für einen vollflächigen Ausgleich der durch das Schneiden entstandenen Ungenauigkeiten.The foam then enters the lamellar plate and provides for you full compensation of the inaccuracies caused by the cutting.
Es hat sich nun überraschender Weise gezeigt, daß bereits eine Klebstoffmenge von 100 - 150- g/qm ausreicht, um diese zuverlässige Verbindung herzustellen.It has now been shown, surprisingly, that already an amount of adhesive from 100 - 150 g / m² is sufficient to establish this reliable connection.
Als Klebstoff können alle bekannten organischen Mittel wie s.B. Polyurethan, Phenolharz, Harnstoffharz, Kautschukkleber und auch anorganische Binder wie z.B. Wasserglas oder Phosphatbinder verwendet werden.All known organic agents such as s.B. Polyurethane, Phenolic resin, urea resin, rubber adhesive and also inorganic binders such as e.g. Water glass or phosphate binders can be used.
Das Aufschäumen kann auf verschiedene Weise erfolgen. Einmal können dem Binder oder Kleber Stoffe zugesetzt werden, die durch Reaktion mit dem Binder oder durch Erwärmen Gas abspalten und somit den Binder zum Aufschäumen bringen. Diese Reaktion kann bereits beim Auftragen des Binders auf die Deckschicht oder kurz nachher erfolgen, jedenfalls jedoch immer vor dem Erhärten des Binders.Foaming can be done in different ways. Can once Substances are added to the binder or adhesive that react with the binder or split off gas by heating and thus cause the binder to foam. This reaction can already occur when the binder is applied to the top layer or take place shortly afterwards, but always before the binder has hardened.
Zum anderen kann das Bindemittel durch mechanisches Rühren, Schlagen oder Wirbeln verschäumt werden, wobei zur Förderung der Schaumbildung geeignete Stoffe zugesetzt werden können. Dann wird die aus dem Bindemittel bestehende Schaumschicht auf die Deckschicht aufgetragen. Schaumbildende gasabspaltende Stoffe sowie Schaumbildung fördernde Stoffe, Schäum- und Auftragsvorrichtungen gehören zum Stand der Technik.On the other hand, the binding agent can be produced by mechanical stirring or beating or whirling are foamed, suitable for promoting foam formation Substances can be added. Then the foam layer consisting of the binder applied to the top layer. Foaming gas-releasing substances and foam formation conveying substances, foaming and application devices belong to the state of the art.
Da die Faserlamellen dem Eindringen des Schaumes keinen großen-Widerstand entgegensetzen, sind nur sehr geringe Drücke oder Auflasten erforderlich während der Erhärtungszeit des Bindes, um eine gleichmäßige Dickenabmessung der Verbundplatte sicherzustellen.Because the fiber lamellas do not have any great resistance to the penetration of the foam oppose only very low pressures or loads are required during the hardening time of the bond to ensure a uniform thickness dimension of the composite panel to ensure.
Weitere Vorteile und Einzelheiten der Erfindung werden im folgenden unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles einer erfindungsgemäßen Verbundplatte näher erläutert.Further advantages and details of the invention are set out below with reference to the drawing using an exemplary embodiment of an inventive Composite panel explained in more detail.
Es zeigt: Fig. 1 eine perspektivische Ansicht einer handelsüblichen Faserlamellenplatte; Fig. 2 eine der Fig. 1 entsprechende Ansicht zur Veranschaulichung desZerschneidens der handelsüblichen Faserlamellenplatte nach Fig. 1; Fig. 3 eine den Fig. 1 und 2 entsprechende Ansicht, jedoch mit den durch das Zerschneiden entstandenen und um 900 gedrehten Streifen der Faserlamellenplatte nach Fig. 1; Fig. 4 eine perspektivische Ansicht im vergrößerten Maßstab einer beidseitig kaschierten Verbundplatte nach der Erfindung ; und Fig. 5 eine vergrößerte Einzelheit der Verbundplatte nach Fig. 4.It shows: Fig. 1 is a perspective view of a commercially available fiber lamella board; FIG. 2 shows a view corresponding to FIG. 1 to illustrate the cutting of the commercially available fiber lamella board according to Fig. 1; Fig. 3 is a view corresponding to FIGS. 1 and 2, but with the through the cutting and twisted strips of the fiber lamellar panel according to Fig. 1; 4 is a perspective view on an enlarged scale of one on both sides laminated composite panel according to the invention; and Fig. 5 is an enlarged detail the composite panel according to FIG. 4.
Zur Durchführung des erfindungsgemäßen Verfahrens und zur Herstellung einer Verbundplatte nach der Erfindung wird eine Mineralfaserplatte (siehe Fig. 1) mit im wesentlichen parallel zur Oberfläche verlaufenden Fasern in Streifen aufgeteilt, wie es schematisch in Fig. 2 dargestellt ist. Diese Streifen werden dann um 900 gedreht und zu einer Paserlamellenplatte zusammengefügt, wie sie in Fig. 3 veranschaulicht ist. Die Fasern stehen nunmehr senkrecht zur Oberfläche.For carrying out the method according to the invention and for production a composite board according to the invention is a mineral fiber board (see Fig. 1) divided into strips with fibers running essentially parallel to the surface, as shown schematically in FIG. These strips will then be around 900 rotated and joined together to form a Paser lamellar plate, as illustrated in FIG. 3 is. The fibers are now perpendicular to the surface.
Das in Fig. 4 dargestellte Verbund element besteht aus einem Kern mit einer Faserlamellenplatte nach Fig. 3. Es ist deutlich erkennbar, daß die Deckschichten 1 keinen vollflächigen Verbund mit dem Faserkern eingehen können, weil die einzelnen Streifen 2 nicht die gleiche Höhe aufweisen. Die Höhe der Streifen 2 entspricht der Schnittbreite, die aber nicht absolut gleichmäßig bei allen Streifen eingehalten werden kann. Diese Ungenauigkeiten werden durch das aufgeschäumte Bindemittel 3 ausgefüllt und ausgeglichen, so daß ein vollflächiger Verbund zwischen Deckschichten 1 und den den Faserkern bildenden Streifen 2 an sämtlichen Stellen sichergestellt ist.The composite element shown in Fig. 4 consists of a core with a fiber lamellar plate according to FIG. 3. It can be clearly seen that the cover layers 1 cannot enter into a full-surface bond with the fiber core because the individual Strips 2 do not have the same height. The height of the strips 2 corresponds the cutting width, which, however, is not absolutely evenly maintained for all strips can be. These inaccuracies are caused by the foamed binder 3 filled and balanced, so that a full-surface bond between Cover layers 1 and the strips 2 forming the fiber core at all points is ensured.
Fig. 5 zeigt deutlich, wie zwischen Deckschicht 1 und Streifen 2 das aufgeschäumte Bindemittel 3 in den Streifen 2 eingedrungen ist, um auf diese Weise die einzelnen Fasern zu umschließen. Durch das Auf schäumen wird nicht nur eine gute und vollständige Verbindung erreicht, sondern es werden gleichzeitig erhebliche Bindemittelmengen gespart.Fig. 5 clearly shows how between cover layer 1 and strip 2 that Foamed binder 3 has penetrated into the strip 2 in order to do this to enclose the individual fibers. The foaming does not result in just one good and complete connection is achieved, but it will be significant at the same time Saving of binder quantities.
Verbundplatten kennen auch aus Deckschichten hergestellt werden, die Profile und Sicken aufweisen. ,wenn derartige Deckschichten verwendet werden, ist es kaum möglich, die Faserplatten den Konturen entsprechend zu schneiden. Durch Verwendung eines aufgeschäumten Binde- oder Klebemittels, z.B.Composite panels are also made from top layers that Have profiles and beads. if such top layers are used, is it is hardly possible to cut the fiberboard according to the contours. By Use of a foamed binder or adhesive, e.g.
Polyurethan, bedingt die Erfindung den weiteren Vorteil, daß die durch die Profilierun, und/oder Sicken vorhandenen Vertiefungen ebenfalls ausgefüllt werden und darüber hinaus eine Verklebung mit den Fasern stattfindet. Deckschichten mit den unterschiedlichsten Profilierungen in ihrer Oberfläche sind bekannt.Polyurethane, the invention causes the further advantage that the through the profiling, and / or beading existing recesses are also filled and, moreover, there is a gluing with the fibers. Top layers with the most varied of profiles in their surface are known.
