Abstract

The Al panel is coated on at least one side with an adherent intermediate layer, which forms an adherent base for the facing plaster. The intermediate layer is pref. a chromate layer or a paint. Buildings provided with thermal insulation need an outer skin as a protection against the weather. Al panels can be used for the skin, and are covered with plaster; but the plaster does not adhere to the Al, so an intermediate layer is used to provide good adhesion for the plaster.

Verfahren zum Beschichten von Aluminiumpaneels mit einem FassadendeckputzProcess for coating aluminum panels with a facade plaster

Die Erfindung betrifft ein Verfahren zum Beschichten von Aluminiumpaneels mit einem Fassadendeckputz, sowie ein Aluminiumpaneel für Fassadenverkleidung/ das einen nach dem Verfahren aufgebrachten Deckputz aufweist.The invention relates to a method for coating aluminum panels with a facade plaster, as well as a Aluminum panel for facade cladding / which has a finishing plaster applied by the process.

Gebäude mit Außenisolationen benötigen für den Wetterschutz der Isolation eine Verkleidung.Buildings with external insulation require cladding to protect the insulation from the elements.

Eine Verkleidung ist bekannt, die aus ineinandergreifenden Paneels aus Aluminiumblech gebildet ist. Auf der Außenseite ist das Aluminium mit einem eingebrannten Lack versehen. Eine neuere Verkleidung ist aus Kunststoffpaneels gebildet. Diese weisen einen rasterförmigen Querschnitt auf und sind auf der Außenseite mit einem Deckputz beschichtet. A cladding is known which is formed from interlocking panels of aluminum sheet. On the outside the aluminum is provided with a burned-in varnish. A newer cladding is made of plastic panels educated. These have a grid-shaped cross-section and are coated on the outside with a finishing plaster.

Die Fassaden mit Verkleidungen aus lackierten Aluminiumpaneels werden als unschön empfunden. Das ästhetische Gefühl hat sich denn auch in Bauordnungen ausgewirkt, so daß in vielen Gemeinden keine Baubewilligungen mehr für solche Fassaden erteilt werden. Die Fassaden die mit/ mit Deckputz beschichteten Kunststoffpaneels aufgebaut sind, haben sich als nicht witterungsfest erwiesen. Bei größerer Kälte unter 150C wird die Struktur dieses Mater rials glashart und es ergeben sich Spannungsrisse.The facades with cladding made of lacquered aluminum panels are perceived as unattractive. The aesthetic feeling has also had an impact on building regulations, so that building permits are no longer issued for such facades in many municipalities. The facades that are built up with / with plaster coated plastic panels have proven to be not weatherproof. With greater cooling below 15 0 C, the structure of this Mater is rials glass hard and there are stress cracks.

Eine Deckputzschicht auf Aluminium auf Aluminium aufzuspritzen, ergab negative Resultate, in dem sich diese Schicht auf der Unterlage als nicht haftend erwies und somit den Witterungseinflüssen auf keinen Fall aussetzbar war. ·Spraying a top coat of plaster on aluminum on aluminum gave negative results, in which these were Layer on the base proved to be non-adhesive and therefore in no way exposed to the effects of the weather was. ·

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu finden, das ein Beschichten von Aluminiumblech mit einem Deckputz haftfest gestattet und damit auch den Bau von Fassadenverkleidungen mit mit einem Deckputz versehenen Aluminiumpaneel gestattet. The invention is based on the object of a method to find, which allows a coating of aluminum sheet with a finishing plaster firmly and thus also the construction of facade cladding with aluminum panel provided with a finishing plaster is permitted.

Erfindungsgemäß wird dies dadurch erreicht, daß das Aluminium auf mindestens einer Seite mit einer haftenden Zwischenschicht versehen wird, auf der dann haftend der Deckputz aufzutragen ist. Die Zwischenschicht kann aus einer Chromatschicht, oder aus einer Haftgruridfarbe gebildet sein.According to the invention this is achieved in that the aluminum has an adhesive on at least one side Intermediate layer is provided on which the finishing plaster is then to be applied in an adhesive manner. The intermediate layer can be made of a chromate layer, or be formed from a primer paint.

Das Aluminiumblech kann zu einem Paneel für Fassadenverkleidung verarbeitet sein, das auf der AuBenseite einen Deckputz aufweist. Im folgenden wird anhand der Zeichnung ein Ausführungsbeispiel des erfindungsgemäßen Verfahrens und damit auch das erfindungsgemäße Aluminiumpaneel näher beschrieben.The aluminum sheet can be processed into a panel for facade cladding that has a Has finishing plaster. An exemplary embodiment of the method according to the invention is described below with reference to the drawing and thus also the aluminum panel according to the invention described in more detail.

Figur 1 ein stark vergrößerter Querschnitt durch ein Aluminiumblech undFigure 1 is a greatly enlarged cross-section through an aluminum sheet and

Figur 2 einen Ausschnitt in perspektivischer Ansicht einer Paneelfassadenverkleidung. FIG. 2 shows a detail in a perspective view of a panel facade cladding.

Das Aluminiumblech 1 ist auf einer Seite chromatisiert. Im wesentlichen ergibt die bekannte Behandlung mit einer Chromschwefel- oder Chromschwefel-Flussäurelösung eine Chromatschicht 2· auf der Oberfläche des Aluminiumblechs. Auf dieser Schicht 2 wird nun der Deckputz 3 aufgespritzt/ ähnlich wie dies auf einem mit einem Unterputz versehenen Mauerwerk geschieht. Statt der Chromatschicht 21 kann auch eine Schicht Haftgrundfarbe 2" auf das entfettete Aluminiumblech 1 aufgebracht werden. Diese Schicht 2" hat sich auch ale ein Mittel erwiesen, auf dem der Deckputz haftfest aufgespritzt werden kann.The aluminum sheet 1 is chromated on one side. Essentially, the known treatment with a chromium-sulfur or chromium-sulfur hydrofluoric acid solution results in a chromate layer 2 on the surface of the aluminum sheet. The finishing plaster 3 is now sprayed onto this layer 2 / similarly to what happens on a masonry provided with a concealed plaster. Instead of the chromate layer 2 1 a layer of pressure sensitive color can "be applied to the degreased aluminum plate 1. This layer 2" 2 has also been found a means ale on which the finish coat adhesive strength can be sprayed.

Aluminiumblechstreifen, die auf ihren Längsseiten Verbindungsbolze 6 aufweisen und die aneinandergereiht überlappt ineinandergreifen, werden als Paneels 5 zu Fassadenverkleidungen verwendet. Ihre AuBenseiten werden vorgängig nach dem Verfahren mit einem Deckputz 3 beschichtet.Aluminum sheet metal strips which have, on their longitudinal sides 6 and Verbindungsbolze mesh overlaps juxtaposed to be used as the panel 5 to facade cladding. Their outside surfaces are coated with a finishing plaster 3 beforehand using the process.

Die im Deckputz enthaltenen Sandkörner 4 und Farbe ergeben ein gefälliges Aussehen der Fassade, die sich 4,n ihrem Äuleren kaum von der Fassade mit einem mit Deckputz versehenen Mauerwerk unterscheidet. The grains of sand 4 and color contained in the top plaster give the facade a pleasing appearance, which 4, in its exterior, hardly differs from the facade with a masonry provided with top plaster.
