Abstract

Add to 2503123. The parent Patent describes the manu. of composite panels or plates, having a core or a facing of fibrous laminated plates, the fibres being perpendicular to the covering plate or layer and constitute a perpendicular connection between two covering layers. In the patent of addition, the binding agent between the fibrous layer and the covering layer is increased in volume by the addition of a filler. PREFERRED Inert powdery materials are used in particular those which have a positive influence by chemical reaction upon the hardening of the adhesive. Examples are rock flour, chalk, kieselguhr, cement, plaster.

Description

Verfahren zum Herstellen von Verbundplatten sowie derartige Verbundplatten. Process for the production of composite panels and composite panels of this type.

Die Erfindung betrifft ein Verfahren und eine Verbundplatte nach dem Patent ... ... (Patentanmeldung P 25 03 123.6) zur Verklebung von Faserlamellenplatten mit Deckschichten. Das Hauptpatent ist darauf gerichtet, daß durch die Volumensvergrößerung des Klebemittels durch Aufschäumen folgende erfindungsgemäßen Vorteile erreicht werden: 1. Es wird etwa 2/3 der Klebstoffmenge eingespart gegenüber der Verwendung von ungeschumter Klebstoff.The invention relates to a method and a composite panel according to the Patent ... ... (patent application P 25 03 123.6) for bonding fiber lamellar panels with top layers. The main patent is aimed at that by increasing the volume of the adhesive achieved the following advantages according to the invention by foaming are: 1. About 2/3 of the amount of adhesive is saved compared to using it of unfoamed adhesive.

2. Die Verbindung der senkrecht stehenden Faser mit der Deckschicht erfolgt zuverlässig durch Eintauchen In eine Klebmittelschicht einer bestimmten --cke.2. The connection of the vertical fiber with the top layer is reliably done by dipping into a specific adhesive layer - corner.

3. Durch die voluminöse Klebmittelschicht werden Unebenheiten zwischen Faserschicht und Deckschicht ausgefüllt, so daß eine satte Verklebung erfolgt.3. The voluminous adhesive layer eliminates unevenness between Filled fiber layer and cover layer, so that a full bond takes place.

Es wurdenun gefunden, daß es ebenfalls möglck ist, den lWrundgedanken des Hauptpatentes dadurch auszuführen, daß die Volumenvergrößerung des Klebmitteis dadurch Zugabe von Füllstoffen erfolgten kann. Als Füllstoff sin alle Inerten mehlfeinen Stoffe wie Steinmehl, Kreide, Kieselgur und auch Zement oder Gips un andere Stoff geeignet. Sie kine den in Hauptpatent genannten Klebmitteln zugesetzt werden. Ebenfalls können solche Füllstoffe zugesetzt werden, die mit dem Klebmittel eine im Sinne der Erhärtung positive Reaktion eingehen.It has now been found that it is also possible to use the basic idea of the main patent in that the increase in volume of the adhesive this means that fillers can be added. As a filler, all inert materials are fine as a flour Substances such as stone flour, chalk, diatomaceous earth and also cement or plaster and other substances suitable. They do not include those mentioned in the main patent Adhesives added will. It is also possible to add fillers that are compatible with the adhesive enter into a positive reaction in terms of hardening.

Die Zugabe von Füllstoffen zum Klebmittel kann bei trockenen mehlfeinen Stoffen zu einem zähen Anteigen der Masse führen, das eine schlechte Adhäsion zur Folge hat. Um die für den Klebvorgang notwendige Viskosität einzustellen, müssen dem mit Füllstoff versetzten Klebmittel Verdünner oder Lösungsmittel in entsprechender Menge zugesetzt werden. Auf diese Weise ist es möglich, trotz der großen Oberfläche des Füllstoffs, den Klebmittelbedarf ebenso niedrig wie in der Verfahrensweise des Hauptpatentes zu halten.The addition of fillers to the adhesive can be fine as flour when dry Substances lead to a tough paste of the mass, which leads to poor adhesion Consequence. In order to set the viscosity necessary for the bonding process, must thinner or solvent in the same way as the adhesive mixed with filler Amount to be added. In this way it is possible, despite the large surface area of the filler, the need for adhesive is just as low as in the procedure of the Hold main patent.
