Abstract

This method improves coating of plastic foam blocks with mortar. A pattern is impressed into the surface of the foam, providing improved adhesion. The impressions should have an undercut on one side. A novel feature is the simultaneous or subsequent treatment of the foam, by needling.

Description

Die Erfindung betrifft ein Verfahren zum Beschichten von Kunst­ stoffschaum, insbesondere mit Mörtel, wobei zur besseren Haftung ein Muster in die Oberfläche des Kunststoffschaumes gedrückt wird und die Eindrücke vorzugsweise mindestens an einer Seite eine Hinterschneidung bilden.The invention relates to a method for coating art foam material, especially with mortar, whereby for better adhesion a pattern is pressed into the surface of the plastic foam and the impressions are preferably at least on one side Form an undercut.

Kunststoffschaumplatten haben im Baubereich eine erhebliche Bedeutung. Sie dienen vorzugsweise der Wärmedämmung. Zunehmend erlangen Kunststoffschaumplatten auch im Sanitärbereich Bedeu­ tung. Dort finden die Kunststoffschaumplatten mit einer Mörtelbe­ schichtung Anwendung. In dieser Form dienen die Kunststoffschaum­ platten als Träger oder Untergrund für Fliesen oder Kacheln. Der besondere Vorteil der mörtelbeschichteten Kunststoffschaumplatten ist ihre leichte Handhabbarkeit. Zudem lassen sich die Platten leicht verarbeiten. Mit einer einfachen Säge können die Platten jeder Raumform angepaßt werden.Plastic foam panels have a considerable amount in the construction sector Meaning. They are preferably used for thermal insulation. Increasingly obtain plastic foam sheets in the sanitary area Bedeu tung. There you will find the plastic foam panels with a mortar stratification application. The plastic foam is used in this form slabs as supports or substrates for tiles or tiles. Of the special advantage of the mortar-coated plastic foam panels is their easy handling. The plates can also be easy to process. The panels can be cut with a simple saw can be adapted to any room shape.

Die Platten selbst werden mit Mörtel oder Klebern an den Gebäude­ wänden oder auf dem Boden verlegt. Gelegentlich werden die Platten zusätzlich mit Dübeln befestigt.The panels themselves are attached to the building with mortar or glue walls or on the floor. Occasionally, the Plates additionally fastened with dowels.

Für die Fliesen und Kacheln bilden die Platten einen hervorragen­ den Untergrund. Der Untergrund ist gerade und definiert. Die Mörtelbeschichtung kann auf den Fliesenkleber ausgelegt werden und umgekehrt. Dadurch können die Fliesen und Kacheln mit minimalem Kleberaufwand und minimalem Arbeitsaufwand auf den Platten verklebt werden.For the tiles and tiles, the plates form an outstanding one the underground. The underground is straight and defined. The Mortar coating can be laid on the tile adhesive and vice versa. This allows the tiles and tiles with minimal adhesive effort and minimal effort on the Panels are glued.

Die Mörtelschicht haftet auf den Kunststoffschaumplatten nicht ohne weiteres. Zur Verbesserung der Haftung ist es bekannt, die Oberfläche des Schaums aufzurauhen. Neuere Verfahren sehen rautenförmige Vertiefungen an der Oberfläche der Kunststoff­ schaumplatten vor. Derartige Vertiefungen werden mit einer Profilwalze eingedrückt. Die Vertiefungen haben nur eine geringe Tiefe, z. B. 1 mm.The mortar layer does not adhere to the plastic foam panels just like that. To improve liability, it is known that Roughen the surface of the foam. See newer procedures diamond-shaped depressions on the surface of the plastic foam sheets before. Such depressions are with a  Profile roller pressed in. The depressions have only a small one Depth, e.g. B. 1 mm.

Durch die nebeneinander liegenden Vertiefungen entsteht ein Oberflächenmuster, z. B. in Form der Rauten. Die Mörtelschicht kann sich bei ihrer Verfestigung in den Vertiefungen verkrallen.The adjacent recesses create a Surface patterns, e.g. B. in the form of diamonds. The mortar layer can claw in the recesses as they solidify.

Der Erfindung liegt die Aufgabe zugrunde, die Haftung des Mörtels an der Kunststoffschaumplatte noch weiter zu verbessern. Nach der Erfindung wird das mit einer Nadelung erreicht. Mit Hilfe der Nadelung entstehen Löcher in der Plattenoberfläche. Die Löcher werden gleichmäßig verteilt, vorzugsweise finden sich die Löcher am Boden der Vertiefungen. Die Gesamtzahl der Löcher und deren Verteilung ist so bemessen, daß sich je cm² Plattenoberfläche 0,2 bis 4 Löcher ergeben. Vorzugsweise ist jede Vertiefung mit einem mittigen Loch versehen. Der Lochdurchmesser beträgt 0,5 bis 3 mm, die Lochtiefe 0,1 bis 1 mm. Zum Lochen können verschiedene Nadeln Anwendung finden. Geeignet sind zylinderische Nadeln mit kegel­ förmiger Spitze und/oder Nadeln mit rautenförmigem Querschnitt und pyramidenförmiger Spitze und/oder Nadeln mit einer Kreuzspit­ ze.The invention has for its object the liability of the mortar to improve on the plastic foam plate even further. After Invention is achieved with a needling. With the help of Needling creates holes in the plate surface. The holes are evenly distributed, preferably the holes are found at the bottom of the wells. The total number of holes and their The distribution is such that there is 0.2 per cm² of plate surface up to 4 holes. Preferably each well is with one provided center hole. The hole diameter is 0.5 to 3 mm, the hole depth 0.1 to 1 mm. Different needles can be used for punching Find application. Cylindrical needles with a cone are suitable shaped tip and / or needles with diamond-shaped cross section and pyramid-shaped tip and / or needles with a cross tip ze.

Die erfindungsgemäße Nadelung bewirkt eine Öffnung der Zellen des Kunststoffschaumes. Bei den angegebenen Lochdurchmessern ist gewährleistet, daß zumindest Mörtelfeuchtigkeit/-flüssigkeit in die geöffneten Zellen bzw. die Löcher eintritt und dort zu einer wichtigen und zusätzlichen Verkrallung der Mörtelschicht führt.The needling according to the invention causes the cells of the Plastic foam. With the specified hole diameters ensures that at least mortar moisture / liquid in the opened cells or the holes enter and there to one important and additional claws of the mortar layer.
