Abstract

A coating for mineral insulating materials is proposed which consists of a combination of a waterglass binder, a stabilising dispersion, mineral fillers and a waterproofing agent, styrene/acrylate being used as the dispersion and silicones being used as the waterproofing agents.

Description

Beschichtung für mineralische DämmstoffeCoating for mineral insulation materials

I Beschichtung für mineralische Dämmstoffe Die Erfindung geht aus von einer Beschichtung für mineralische Dämmstoffe nach der Gattung des Hauptanspruchs. I. Coating for mineral insulation materials The invention is based on a coating for mineral insulation materials according to the genus des Main claim.

Aus der DE-PS 24 55 691 ist eine beschichtete Dämmplatte bekannt, die aus einer Mineralfaserplatte und einer wenigstens einseitig aufgebrachten Beschichtung aus Wasserglas und einem Zusatz an mineralischen Stoffen besteht. Die Mineralfaserplatten, die als Dachdämmplatten aber auch als Platten für Fassadenverkleidungen verwendet werden, müssen die Beschichtung aufweisen, damit das zum Verlegen der Dachhaut auf die Platte aufzubringende flüssige Bitumen beziehungsweise der auf die Fassadenverkleidung aufzubringende Putz nicht ins Innere der Platten eindringen kann, da sonst die Dämmeigenschaften verringert werden.From DE-PS 24 55 691 a coated insulation board is known, the one made of a mineral fiber board and a coating applied to at least one side consists of water glass and an addition of mineral substances. The mineral fiber boards, which are used as roof insulation panels but also as panels for facade cladding must have the coating in order to allow the laying of the roof cladding on the liquid bitumen to be applied to the panel or to the facade cladding The plaster to be applied cannot penetrate the interior of the panels, otherwise the insulation properties be reduced.

Die bekannte Beschichtung besteht aus einer Zusammensetzung aus Wasserglas, tonmineralischen Stoffen, Oxide oder Karbonate der Erdalkalien oder des Zinks, Oxide oder Hydroxide des Aluminiums und/oder Bariumsulfat, aus Pigmenten und Wasser. Bei Aufbringen der Beschichtung bildet sich aufgrund der Zusätze zum Wasserglas ein zusammenhängender Film, bei dem es nicht zu einer Rißbildung infolge Versprödung kommt. Diese Beschichtung kann aber vor dem Auftragen nur eine begrenzte Zeit gelagert werden, da sie relativ schnell eindickt.The well-known coating consists of a composition of water glass, clay mineral substances, oxides or carbonates of alkaline earths or zinc, oxides or hydroxides of aluminum and / or barium sulfate, from pigments and water. at The coating is applied due to the additives to the water glass coherent film that does not crack as a result of embrittlement comes. However, this coating can only be stored for a limited time before application as it thickens relatively quickly.

Aufgabe der vorliegenden Erfindung ist es daher, eine Beschichtung für Dämmstoffe zu schaffen, die vor dem Auftragen lange lagerfähig ist, wobei nach dem Auftragen die Beschichtung eine erhöhte Druckfestigkeit und eine griffige Oberfläche aufweisen soll.The object of the present invention is therefore to provide a coating for insulation materials that can be stored for a long time before application, whereby after after application, the coating has an increased compressive strength and a non-slip surface should have.

Diese Aufgabe wird erfindungsgemäße durch die kennzeichnenden Merkmale des Hauptanspruchs in Verbindung mit den Merkmalen des Oberbegriffs gelöst. Durch die Zusetzung eines Stabilisators zu der Mischung aus Wasserglas und mineralischen Stoffen wird das Eindicken verhindert und damit die Lagerfähigkeit wesentlich verbessert. Das darüber hinaus zugemischte Hydrophobierungsmittel dient zur weiteren Verminderung der Wasseraufnahme.This object is achieved according to the invention by the characterizing features of the main claim solved in connection with the features of the preamble. By the addition of a stabilizer to the mixture of water glass and mineral Substances are prevented from thickening and thus their shelf life is significantly improved. The water repellant added in addition serves to reduce this further the water absorption.

Die erfindungsgemäße Beschichtung aus der Kombination eines Bindemittels aus Wasserglas, der mineralischen Füllstoffe, der Dispersion zum Stabilisieren der Mischung und des Hydrophobierungsmittels gegebenenfalls unter Zusatz von Wasser wird bei Temperaturen zwischen +100 und +300 C hergestellt und auf Mineralfaserplatten oder dergleichen mittels Streichen, Rollen, Spritzen oder Tauchen aufgebracht. Die Aushärtung kann je nach vorgegebenen Trocknungsbedingungen und gewünschtem Effekt bei Temperaturen zwischen 200 und 2000 C erfolgen, wobei IR-Strahler oder andere Wärmequellen verwendet werden können.The coating according to the invention from the combination of a binder made of water glass, the mineral fillers, the dispersion to stabilize the Mixture and the water repellent, if appropriate with the addition of water is produced at temperatures between +100 and +300 C and on mineral fiber boards or the like applied by brushing, rolling, spraying or dipping. the Curing can take place depending on the specified drying conditions and the desired effect take place at temperatures between 200 and 2000 C, with IR radiators or others Heat sources can be used.

Als Stabilisator in Form der Dispersion wird eine Styrol-Acrylat-Dispersion verwendet; als mineralische Füllstoffe dienen calsitische Füllstoffe und das Hydrophobierungsmittel wurde in Form von Siliconen gewählt. Als vorteilhaft hat sich folgende Zusammensetzung der Beschichtung erwiesen: Wasserglas als Bindemittel, je nach Konzentration zwischen 20 und 40 Gew.%, der Stabilisator in Form der Styrol-Acrylat-Dispersion zwischen 5 und 10 Gew.%, die calsitischen Füllstoffe bis zu 50 % und das Hydrophobierungsmittel in Form von Siliconen bis zu 1 Gew.%, wobei gegebenenfalls Wasser zugemischt wird.A styrene-acrylate dispersion is used as a stabilizer in the form of the dispersion used; The mineral fillers used are calsitic fillers and the water repellent was chosen in the form of silicones. The following composition has proven to be advantageous of the coating: water glass as a binding agent, depending on the concentration between 20 and 40% by weight, the stabilizer in the form of the styrene-acrylate dispersion between 5 and 10% by weight, the calsitic fillers up to 50% and the water repellent in the form of silicones up to 1% by weight, with water optionally being added.
