Description
Die Erfindung bezieht sich auf ein flüssiges Imprägniermittel für Faserzementplatten und die Verwendung eines solchen Imprägniermittels.The invention relates to a liquid impregnating agent for fiber cement boards and the use of such an impregnating agent.
Faserzementplatten neigen dazu, Feuchtigkeit aus der Luft bzw. vom Regenwasser aufzunehmen und dann auszublühen.Fiber cement boards tend to absorb moisture from the air or rainwater and then bloom.
Der Erfindung liegt die Aufgabe zugrunde, ein Imprägniermittel und eine Verwendung dieses Impräghniermittels aufzuzeigen, mit dem diese ungewollten Erscheinungen abgestellt werden können.The invention has the object of demonstrating an impregnating agent and a use of this impregnating agent, with which these unwanted phenomena can be turned off.
Diese Aufgabe wird erfindungsgemäß durch ein Imprägniermittel bestehend aus
- – 5 bis 20 Gew.-% nicht fluoriertes Polyacrylatharz,
- – 5 bis 40 Gew.-% Alkylalkoxysilan und/oder Alkylalkoxysiloxan
- – 50 bis 85 Gew.-% deionisiertes Wasser, gelöst.
- 5 to 20% by weight of non-fluorinated polyacrylate resin,
- 5 to 40% by weight of alkylalkoxysilane and / or alkylalkoxysiloxane
- - 50 to 85 wt .-% deionized water, dissolved.
Diese Imprägnierung verhindert das Eindringen von Luftfeuchtigkeit und Wasser sehr wirksam, so daß auch keinerlei Ausblühen eintreten kann.This impregnation prevents the ingress of humidity and water very effectively, so that no blooming can occur.
Eine sehr vorteilhafte Ausgestaltung des erfindungsgemäßen Imprägniermittels liegt vor, wenn das Mittel besteht aus:
- – 70 Gew.-% deionisiertes Wasser,
- – 10 Gew.-% Polyacrylatharz
- – 20 Gew.-% Alkylalkoxysilan und -siloxan.
- 70% by weight of deionized water,
- 10% by weight of polyacrylate resin
- 20% by weight of alkylalkoxysilane and siloxane.
Mit dieser Zusammensetzung wurden besonders gute Ergebnisse erzielt.Particularly good results were achieved with this composition.
Eine erfindungsgemäß sehr vorteilhafte Verwendung eines solchen Imprägniermittels liegt vor, wenn das Mittel zum Imprägnieren von Faserzementplatten eingesetzt wird.An inventively very advantageous use of such an impregnating agent is present when the means for impregnating fiber cement boards is used.
Hiermit wird verhindert, dass neue Feuchtigkeit in die Faserzementplatte eindringen kann.This prevents new moisture from entering the fiber cement board.
Dabei kann die Faserzementplatte unmittelbar nach der Herstellung und zwar sobald alle Feuchtigkeit des Herstellungsprozesses entwichen ist und vorzugsweise allseitig mit einem Imprägniermittel behandelt werden. Aber auch eine Behandlung auf einer Seite mit einem flüssigen Mittel ist denkbar, das eine Imprägnierung der Platte gegen Feuchtigkeitseintritt bewirkt.In this case, the fiber cement board immediately after production and that as soon as all the moisture of the manufacturing process has escaped and preferably treated on all sides with an impregnating agent. But a treatment on one side with a liquid agent is conceivable, which causes an impregnation of the plate against moisture.
Dabei kann das Imprägniermittel auf die Oberfläche der Faserzementplatte aufgesprüht, die Fazerzementplatte getaucht oder geflutet werden.In this case, the impregnating agent sprayed onto the surface of the fiber cement board, the Fazerzementplatte be dipped or flooded.
Ein Walzenauftrag auf die Faserzementplatte ist aber ebenso denkbar wie ein Spülprozesses, wobei die Faserzementplatte anschließend abgeblasen wird.A roll application to the fiber cement board is also conceivable as a rinsing process, wherein the fiber cement board is then blown off.
Anhand eines Ausführungsbeispiels soll im folgenden die Erfindung erläutert werden.Reference to an embodiment of the invention will be explained below.
Eine Faserzementplatte wird bei verhältnismäßig hoher Temperatur gehärtet und getrocknet. Dabei entweicht das im Zementbrei enthaltene Wasser nahezu vollständig.A fiber cement board is cured at a relatively high temperature and dried. The water contained in the cement slurry escapes almost completely.
Nach einer zumindest teilweisen Abkühlung wird die Faserzementplatte einseitig mit einem flüssigen Mittel gleichmäßig besprüht. Das Mittel besteht aus 70 Gewichtsanteilen deionisiertem Wasser, 10 Gewichtsanteilen Polyacrylatharz sowie 20 Gewichtsanteilen Alkylalkoxysilan und -siloxan. Beim ersten Auftrag dringt das Mittel weitgehend in das Material ein und ergibt einen sehr hohen Feuchtigkeitsschutz, während der zweite Auftrag wenigstens zum Teil einen Oberflächenschutz bildet. Dieses Mittel ergibt damit nicht nur einen hohen Feuchtigkeitsschutz für die Faserzementplatte sondern auch einen hohen Oberflächen-Schutz.After at least partial cooling, the fiber cement board is evenly sprayed on one side with a liquid agent. The agent consists of 70 parts by weight of deionized water, 10 parts by weight of polyacrylate resin and 20 parts by weight of alkylalkoxysilane and siloxane. During the first application, the agent penetrates largely into the material and gives a very high moisture protection, while the second application at least partially forms a surface protection. This means not only provides a high moisture protection for the fiber cement board but also a high surface protection.
Anstelle des Aufsprühens sind auch andere Auftragstechniken, wie Tauchen, Fluten, Walzenauftrag oder mittels eines Spülprozesses, möglich.Instead of spraying, other application techniques, such as dipping, flooding, roller application or by means of a rinsing process, are possible.
Der Anteil an Alkylalkoxysilan und -siloxan hydrophobiert in der Platte, das Polyacrylatharz konserviert die Plattenoberfläche gegen Verschmutzungen.The proportion of alkylalkoxysilane and siloxane hydrophobicized in the plate, the polyacrylate resin protects the plate surface against contamination.
Das flüssige Mittel zum Imprägnieren von Faserzementplatten, das nach dem Herstellen der Platten auf wenigstens eine Oberfläche aufgebracht wird, ist ein wässriges Mittel, in welchem Polyacrylatharz mit einem Anteil von 5 bis 20 Gew.-% vorhanden ist.The liquid agent for impregnating fiber cement boards applied to at least one surface after the manufacture of the boards is an aqueous agent in which polyacrylate resin is present at a content of 5 to 20% by weight.
Mit diesem wässrigen Mittel wird erreicht, daß das Harz in die Oberfläche der Faserzementplatte eindringt und dadurch eine wirksame Imprägnierung bewirkt.With this aqueous agent is achieved that the resin penetrates into the surface of the fiber cement board and thereby causes an effective impregnation.
Weiterhin sind in dem wässrigen Mittel Alkylalkoxysilan und/oder Alkoxysiloxan mit einem Anteil von 5 bis 40 Gew.-% vorhanden.Furthermore, in the aqueous agent alkylalkoxysilane and / or alkoxysiloxane in a proportion of 5 to 40 wt .-% present.
Dabei hat es sich als besonders günstig erwiesen, wenn in dem Mittel ein Wasseranteil von 50 bis 85 Gew.-% enthalten ist. Dieses Wasser ist deionisiert.It has proved to be particularly advantageous if in the agent, a water content of 50 to 85 wt .-% is included. This water is deionized.
Ein besonders günstiges Mittel weist im Mittel 70 Gew.-% deionisiertes Wasser, 10 Gew.-% Polyacrylatharz und 20 Gew.-% Alkylalkoxysilan und -siloxan enthalten sind.A particularly favorable agent comprises on average 70 wt .-% deionized water, 10 wt .-% polyacrylate resin and 20 wt .-% alkylalkoxysilane and siloxane are included.
Mit dieser Zusammensetzung wurden optimale Imprägnierungen der Faserzementplatten erzielt.With this composition, optimum impregnations of the fiber cement boards were achieved.
Eine mit einer solchen Imprägnierung behandelte Faserzementplatte neigt bei Verwendung im Freien nicht zu Ausblühungen.A fiber cement board treated with such impregnation is not prone to efflorescence when used outdoors.
Dabei wird eine der Oberflächen der Faserzementplatte durch ein aufgebrachtes Mittel hydrophobisch eingestellt ist.In this case, one of the surfaces of the fiber cement board is hydrophobically adjusted by an applied agent.
Dadurch kann keine Feuchtigkeit in das Material der Platte eindringen, womit ein Ausblühen wirksam verhindert ist.As a result, moisture can not penetrate into the material of the plate, whereby efflorescence is effectively prevented.
Dabei kann die imprägnierte Oberfläche auch schmutzabweisend sein.The impregnated surface can also be dirt-repellent.
Faserzementplatten sind aufgrund ihrer rauhen Oberfläche an sich schmutzempfindlich, was durch die Imprägnierung kompensiert wird.Fiber cement boards are sensitive to dirt due to their rough surface, which is compensated by the impregnation.
Wesentlich ist auch, daß die Faserzement-Platten nach der Imprägnierung eine verminderte hygrische Dehnung aufweisen.It is also essential that the fiber cement boards have a reduced hygric elongation after impregnation.
