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 Dekorpapier sowie 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.The invention relates to a decorative paper and a method for Impregnation for the manufacture of highly abrasion-resistant laminate flooring materials used decorative paper, in which the Decor paper first moistened with an amino resin and thereby impregnated and the resin content is regulated.

Es ist aus der Druckschrift EP 0 732 449 A1 bekannt, 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 A1, highly abrasion-resistant for laminate flooring materials To produce decorative paper impregnates. In this well-known The process is carried out after the actual impregnation Decorative paper applied a mass at the particulate Corundum due to special viscosity increasing substances is kept stable in a dispersion forming the mass.

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

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 dead zones with low mass movement form. Therefore the corundum particles settle quickly, which inhomogeneity in the Corundum application on the decorative paper and therefore 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. Außerdem soll der Korund relativ feinkörnig sein, da sich leichtere bzw. feinere Korund-Partikel weniger schnell absetzen. Der Einsatz von Cellulosederivaten führt jedoch zu einer optischen Vergrauung der Oberfläche der hergestellten Laminat-Fußbodenmaterialien. For this reason, substances that increase viscosity, usually cellulose derivatives, the corundum mixture containing mass added. The corundum is also said to be relative be fine-grained, since there are lighter or finer corundum particles stop less quickly. The use of cellulose derivatives however, leads to an optical graying of the surface of the manufactured laminate flooring materials.

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 is, the more it needs to be proportionate The decor paper can be applied to provide adequate abrasion values to achieve. This also causes the surface to gray of the materials produced.

Aus der deutschen Offenlegungsschrift 2 110 605 ist ein Verfahren zur Beschichtung von Presskörpern bekannt, gemäß dem eine mit Harz durch Sprühen durchtränkte Beschichtungsfolie mit stark zerkleinerten, harten Mineralien bestreut wird. Die Folie besteht aus Cellulose und soll als Schutzschicht für ein Dekorpapier verwendet werden.From German published application 2 110 605 is a Process for coating compacts known, according to the a coating film impregnated with resin by spraying heavily crushed, hard minerals is sprinkled. The foil consists of cellulose and is intended as a protective layer for a Decorative paper can be used.

Nachteilhaft ist es teuer, eine separate Celluloseschicht herzustellen, zumal diese den optischen Eindruck eines Dekorpapiers nachteilhaft relativ stark beeinträchtigt. Bei einem solchen Verfahren ist ferner schwierig, eine hinreichend gleichmäßige Verteilung auf der Oberfläche zu erreichen.Disadvantageously, it is expensive to have a separate cellulose layer to manufacture, especially since this gives the visual impression of a Decorative paper disadvantageously relatively badly affected. at Such a procedure is also difficult, one sufficient to achieve even distribution on the surface.

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 above Disadvantages of the known manufacture described avoid highly abrasion-resistant laminate flooring materials and highly abrasion-resistant decorative laminate flooring materials to be able to produce, which is the surface structure decorative paper showing evenly with particulate corundum or aluminum oxide is coated without the surface of the Floor materials produced in this way have graying.

Diese Aufgabe wird gemäß der vorliegenden Erfindung mit einem Verfahren sowie einem Dekorpapier gelöst, welches die Merkmale der unabhängigen Patentansprüch aufweist.This object is achieved according to the present invention with a Process as well as a decorative paper solved, which the characteristics which has independent claims.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der abhängigen Unteransprüche.Advantageous refinements and developments of the invention are the subject of the 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 invention The method consists in that the impregnation of the Decorative paper and for applying abrasion particles such as corundum particles or mass used of alumina particles or Dispersion is sprayed or applied in the nozzle principle.

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. 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.The nozzle principle has the advantage over the roller application that that the abrasive body containing corundum particles Dispersion constantly and completely circulated before application and is moved more or less uniformly. Consequently are not signs of discontinuity leading to irregularities determine. Therefore, the admixture of viscosity-increasing substances or substances are dispensed with become. In fact, flow aids can even be used like a better distribution of the abrasion material Corundum is what causes the material to compress press used is advantageous.

Die endgültige Flächenmasse des verfahrensgemäß hergestellten Dekorpapiers beträgt - bezogen auf die Trockenmasse des Rohpapiers - insbesondere 100% bis 250%. The final basis weight of the process manufactured Decorative paper is - based on the dry weight of the Base paper - especially 100% to 250%.

Ein weiterer Vorteil besteht darin, daß nicht auf eine besondere Feinkörnigkeit des Siliciumcarbids 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 silicon carbide Corundum or aluminum oxide must be respected, but that corundum or other particulate abrasion material with significantly larger or coarser grain size can be used. This in turn means that relatively small amounts Corundum or other particulate abrasion material is needed to make higher To achieve 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 Apply the mass or dispersion used for impregnation using Spreading rollers with relatively slow impregnation speeds of For example, 18 to 25 m / min must drive to a reasonably constant To ensure order, but that with the inventive method, at to which the mass or dispersion is applied by means of nozzles, impregnation speeds can reach or realize between 40 to 50 m / min.
