Abstract

Decorative paper for use in high abrasion resistant laminate flooring is impregnated by an amine resin. The paper has an additional layer of amine resin. The layer weighs 100-250% of the dry weight of the paper.

Description

Die Erfindung betrifft ein Verfahren zum Imprägnieren von zum Herstellen hochabriebfester Laminat-Fußbodenmaterialien verwendeten Dekorpapieren, bei dem das Dekorpapier zunächst mit einem Aminoharz angefeuchtet und dadurch imprägniert sowie dabei der Harzgehalt geregelt wird. Die Erfindung betrifft ferner ein verfahrensgemäß hergestelltes Dekorpapier.The invention relates to a method for impregnating for manufacturing highly abrasion-resistant laminate flooring materials used decorative paper, at which the decorative paper is moistened with an amino resin and thereby impregnated and the resin content is regulated. The invention relates also a decorative paper produced according to the method.

Es ist aus der EP 0 732 449 B1 bekannt (Patent von Graudenz u.a.), für Laminat-Fußbodenmaterialien hochabriebfeste Dekorpapierimprägnate herzustellen. Bei diesem bekannten Verfahren wird nach dem eigentlichen Imprägnieren auf das Dekorpapier eine Masse aufgebracht, bei der partikelförmiges Korund durch spezielle viskositätserhöhende Substanzen relativ stabil in einer die Masse bildenden Dispersion gehalten wird.It is known from EP 0 732 449 B1 (Graudenz et al. Patent) for laminate flooring materials produce highly abrasion-resistant decorative paper impregnates. at this known method is after the actual impregnation on the Decorative paper applied a mass, through which particulate corundum special viscosity increasing substances relatively stable in a mass forming dispersion is maintained.

Dabei wird die Masse mittels Aufstreichwalzen noch in der Naßphase direkt nach dem Imprägnieren oder aber in einer Zwischentrocknungsstufe aufgetragen.The mass is applied directly in the wet phase by means of spreading rollers impregnation or applied in an intermediate drying stage.

Bei dieser bekannten Technologie der Verwendung von Aufstreichwalzen befindet sich die Korund-haltige Masse in Vorratswannen, in denen sich Totzonen mit geringer Massenbewegung bilden. Daher setzen sich die Korund-Partikel schnell ab, was Inhomogenität im Korundauftrag auf dem Dekorpapier und damit erhebliche Schwankungen in den Abriebwerten so hergestellter Laminat-Fußbodenmaterialien zur Folge hat.With this known technology the use of spreading rollers the corundum-containing mass is in storage tanks in which there are dead zones form with little mass movement. Therefore the corundum particles settle quickly what is inhomogeneity in the corundum application on the decorative paper and thus considerable fluctuations in the abrasion values of laminate flooring materials produced in this way has the consequence.

Aus diesem Grund werden bisher viskositätserhöhende Substanzen, in der Regel Cellulosederivate, der die Korundmischung enthaltenden Masse zugesetzt. Außerdern soll der Korund relativ feinkörnig sein, da sich leichtere bzw. feinere Korund-Partikel weniger schnell absetzen. So liegt die Korngröße gemäß der EP 0 732 449 A1 bei 300 bis 900 mesh. Diese beträgt somit 15 bis 48 µm. Der Einsatz von Cellulosederivaten führt jedoch zu einer optischen Vergrauung der Oberfläche der hergestellten Laminat-Fußbodenmaterialien. For this reason, viscosity-increasing substances are usually used Cellulose derivatives added to the mass containing the corundum mixture. In addition, the corundum should be relatively fine-grained, because lighter or finer Settling corundum particles less quickly. So the grain size is according to the EP 0 732 449 A1 at 300 to 900 mesh. This is 15 to 48 µm. The However, the use of cellulose derivatives leads to an optical graying of the Surface of the laminate flooring materials produced.

Je feinkörniger der Korund ist, desto mehr muß anteilmäßig auf das Dekorpapier aufgetragen werden, um ausreichende Abriebwerte zu erzielen. Auch dadurch wird eine Vergrauung der Oberfläche der hergestellten Materialien herbeigeführt.The more fine-grained the corundum, the more must be applied proportionally to the decorative paper in order to achieve sufficient abrasion values. This also causes graying of the Surface of the materials produced.

Aus der Druckschrift DE-OS 21 20 605 ist ein Verfahren zur Beschichtung von Presskörpern bekannt, gemäß dem ein Dekorpapier durch Besprühen imprägniert wird. Anschließend werden stark zerkleinerte, abriebfeste Partikel auf das imprägnierte Papier gestreut. Dieses Verfahren hat sich in der Praxis nicht durchsetzen können.From the document DE-OS 21 20 605 is a method for coating Press bodies known, according to which a decorative paper is impregnated by spraying. Then severely crushed, abrasion-resistant particles are impregnated on the Scattered paper. This method has not been able to prevail in practice.

Gemäß der Druckschrift EP 0 186 257 A2 wird eine Suspension auf ein Papier aufgetragen, die sehr kleine abriebfeste Partikel sowie Cellulose enthält, um eine ultradünne abriebfeste Schicht auftragen zu können.According to EP 0 186 257 A2, a suspension is placed on a paper applied, which contains very small abrasion-resistant particles and cellulose to a to be able to apply an ultra-thin, abrasion-resistant layer.

Der Erfindung liegt die Aufgabe zugrunde, die zuvor geschilderten Nachteile der bekannten Herstellung hochabriebfester Laminat-Fußbodenmaterialien zu vermeiden und hochabriebfeste dekorative Laminat-Fußbodenmaterialien herstellen zu können, wobei das die Oberflächenstruktur zeigende Dekorpapier gleichmäßig mit partikelförmigem Korund oder Aluminiumoxid beschichtet ist, ohne daß die Oberfläche der so hergestellten Fußbodenmaterialien eine Vergrauung aufweist.The invention has for its object the disadvantages of the known Avoid manufacturing and highly abrasion-resistant laminate flooring materials to be able to produce highly abrasion-resistant decorative laminate flooring materials Decorative paper showing surface structure evenly with particulate corundum or Alumina is coated without the surface of the so produced Floor materials have a graying.

Diese Aufgabe wird gemäß der vorliegenden Erfindung mit einem Verfahren gelöst, welches die Merkmale des unabhängigen Patentanspruches 1 aufweist sowie durch ein Papier mit den Merkmalen des Nebenanspruchs.This object is achieved according to the present invention with a method which has the features of independent claim 1 and with a paper the characteristics of the subsidiary claim.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der abhängigen Unteransprüche.Advantageous refinements and developments of the invention are the subject of dependent subclaims.

Einer der wesentlichen Unterschiede des erfindungsgemäßen Verfahrens besteht darin, daß die zum Imprägnieren des Dekorpapiers und zum Aufbringen der Abriebkörper wie Korund-Partikel oder Aluminiumoxid-Partikel verwendete Masse oder Dispersion aufgedüst bzw. im Düsenprinzip aufgetragen wird.One of the main differences of the method according to the invention is that those for impregnating the decorative paper and for applying the abrasive particles such as corundum particles or alumina particles used or sprayed in or im Nozzle principle is applied.

Das Düsenprinzip hat gegenüber dem Walzenauftrag den Vorteil, daß die die Abriebkörper wie Korund-Partikel enthaltende Dispersion vor dem Auftrag ständig und vollständig umgewälzt und damit mehr oder weniger gleichförmig bewegt wird. Somit sind zu Ungleichförmigkeiten führende Absetzerscheinungen nicht festzustellen. Deshalb kann auch auf die Beimischung von viskositätserhöhenden Stoffen oder Substanzen verzichtet werden. The nozzle principle has the advantage over the roller application that the wear body like dispersion containing corundum particles constantly and completely before application is circulated and thus moved more or less uniformly. So are too Unevenness leading sedimentation not to be determined. Therefore, too the admixture of viscosity-increasing substances or substances can be dispensed with.

Vielmehr können sogar Fließhilfsstoffe eingesetzt werden, die eine bessere Verteilung des Abriebmaterials wie Korund bewirken, was in der zum Komprimieren des Materials verwendeten Presse vorteilhaft ist.Rather, flow aids can even be used, the better distribution of the Abrasion material such as corundum cause what in the compression of the material press used is advantageous.

Ein weiterer Vorteil besteht darin, daß nicht auf eine besondere Feinkörnigkeit des Korunds oder Aluminiumoxids geachtet werden muß, sondern daß Korund oder anderes partikelförmiges Abriebmaterial mit deutlich größerer oder gröberer Korngröße eingesetzt werden kann. Das hat wiederum zur Folge, daß relativ geringe Mengen Korund oder sonstiges partikelförmiges Abriebmaterial benötigt wird, um höhere Abriebwerte zu erreichen.Another advantage is that there is no particular fine grain of the corundum or aluminum oxide must be respected, but that corundum or other particulate abrasion material with a significantly larger or coarser grain size is used can be. This in turn has the consequence that relatively small amounts of corundum or the like particulate abrasion material is required to achieve higher abrasion values.

Die Folge dieser Maßnahmen und Vorteile ist, daß besonders transparente und brilliante Oberflächen von Laminat-Fußbodenmaterialien erfindungsgemäß erzielt werden können.The consequence of these measures and advantages is that they are particularly transparent and brilliant Surfaces of laminate flooring materials can be achieved according to the invention.

Ein weiterer Vorteil der Erfindung liegt darin, daß man nicht, wie beim bekannten Auftragen der zum Imprägnieren verwendeten Masse oder Dispersion mittels Aufstreichwalzen mit verhältnismäßig langsamen Imprägniergeschwindigkeiten von beispielsweise 18 bis 25 m/min fahren muß, um einen einigermaßen gleichbleibenden Auftrag zu gewährleisten, sondern daß man mit dem erfindungsgemäßen Verfahren, bei welchem die Masse bzw. Dispersion mittels Düsen aufgetragen wird, Imprägniergeschwindigkeiten zwischen 40 bis 50 m/min erreichen bzw. realisieren kann.Another advantage of the invention is that you do not, as in the known application the mass or dispersion used for impregnation with spreading rollers relatively slow impregnation speeds of, for example, 18 to 25 m / min to ensure a reasonably constant order, but that with the method according to the invention, in which the mass or Dispersion is applied by means of nozzles, impregnation speeds between 40 to 50 m / min can achieve or realize.
