Eine weitere Aufgabe der Erfindung liegt darin, ein Mittel aufzuzeigen, mit dem die Behandlung der Faserzementplatte vorteilhaft erfolgen kann. Another object of the invention is to provide a means by which the Treatment of the fiber cement board can be done advantageously.
Diese Aufgabe wird erfindungsgemäß mit einem flüssigen Mittel zum Imprägnieren von Faserzementplatten oder dergleichen gelöst, das nach dem Herstellen der Platten auf wenigstens eine Oberfläche aufgebracht wird, wobei ein wässriges Mittel vorliegt, in welchem Polyacrylatharz mit einem Anteil von 5 bis 20% vorhanden ist.This object is achieved according to the invention with a liquid agent for impregnation solved by fiber cement boards or the like, that after the manufacture of the boards is applied to at least one surface, an aqueous medium being present, in which polyacrylate resin is present with a share of 5 to 20%.
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 it is achieved that the resin in the surface of the Fiber cement board penetrates and thereby causes an effective impregnation.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, daß in dem wässrigen Mittel Alkylalkoxysilan mit einem Anteil von 5 bis 40% vorhanden ist.According to a further advantageous embodiment of the invention it is provided that present in the aqueous medium alkylalkoxysilane in a proportion of 5 to 40% is.
Dieses Alkylalkoxysilan kann in Verbindung mit Polyacrylatharz in dem wässerigen Mittel eingesetzt werden.This alkylalkoxysilane can be used in conjunction with polyacrylate resin in the aqueous Means are used.
Darüber hinaus kann gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung in dem wässrigen Mittel Alkylalkoxysiloxan mit einem Anteil von 5 bis 40% enthalten sein.In addition, according to a further advantageous embodiment of the invention contained in the aqueous medium alkylalkoxysiloxane in a proportion of 5 to 40% his.
Dabei hat es sich als besonders günstig erwiesen, wenn gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung in dem Mittel ein Wasseranteil von 50 bis 85% enthalten ist.It has proven to be particularly favorable if according to another advantageous embodiment of the invention in the mean a water content of 50 to 85% is included.
Dieses Wasser ist gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung deonisiert.This water is according to a further advantageous embodiment of the invention deonisiert.
Ein als besonders günstig erwiesenes Mittel ist dadurch gekennzeichnet, daß im Mittel 7 Gewichtsanteile deionisiertes Wasser, 10 Gewichtsanteile Polyacrylatharz und 20 Gewichtanteile Alkylalkoxysilan und -siloxan enthalten sind. A proven to be particularly favorable agent is characterized in that on average 7 parts by weight of deionized water, 10 parts by weight of polyacrylate resin and 20 Parts by weight of alkylalkoxysilane and siloxane are included.
Mit dieser Zusammensetzung wurden optimale Imprägnierungen der Faserzementplatten erzielt.With this composition, optimal impregnation of the Fiber cement boards achieved.
Der Erfindung liegt weiterhin die Aufgabe zugrunde, eine Faserzementplatte so auszugestalten, daß sie bei Verwendung im Freien nicht zu Ausblühungen neigt.The invention is also based on the object of a fiber cement board To design that it does not tend to efflorescence when used outdoors.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei einer Faserzementplatte mit einer Imprägnierung wenigstens einer ihrer Oberflächen, die imprägnierte Oberfläche durch ein aufgebrachtes Mittel hydrophobisch eingestellt ist.This object is achieved in that in a fiber cement board with an impregnation of at least one of its surfaces, the impregnated Surface is made hydrophobic by an applied agent.
Dadurch kann keine Feuchtigkeit in das Material der Platte eindringen, womit ein Ausblühen wirksam verhindert ist.As a result, no moisture can penetrate into the material of the plate, with which a Efflorescence is effectively prevented.
Eine weitere vorteilhafte Ausgestaltung der Erfindung ist dadurch gegeben, daß die imprägnierte Oberfläche schmutzabweisend ist.A further advantageous embodiment of the invention is given in that the impregnated surface is dirt-repellent.
Faserzementplatten sind aufgrund ihrer rauhen Oberfläche ansich schmutzempfindlich, was durch die Imprägnierung kompensiert ist.Due to their rough surface, fiber cement boards are sensitive to dirt, which is compensated by the impregnation.
Als sehr vorteilhaft hat es sich auch ergeben, wenn gemäß einer weiteren Ausgestaltung der Erfindung die Faserzement-Platten nach der Imprägnierung eine verminderte hygrische Dehnung aufweisen.It has also turned out to be very advantageous if according to another Embodiment of the invention, the fiber cement panels after impregnation have reduced hygric elongation.
Anhand eines Ausführungsbeispiels soll im folgenden die Erfindung erläutert werden.The invention will be explained below using an exemplary embodiment.
Eine Faserzementplatte wird bei verhältnismäßig hoher Temperatur gehärtet und getrocknet. Dabei entweicht das im Zementbrei enthaltene Wasser nahezu vollständig. Nach einer zumindest teilweisen Abkühlung wird die Faserzementplatte einseitig mit einem flüssigen Mittel gleichmäßig besprüht. Das Mittel enthält dabei 70 Gewichtsanteile deionisiertes Wasser, 10 Gewichtsanteile Polyacrylatharz sowie 20 Gewichtsanteile 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.A fiber cement board is hardened and at a relatively high temperature dried. The water contained in the cement paste escapes almost completely. After at least partial cooling, the fiber cement board becomes one-sided evenly sprayed with a liquid agent. The remedy contains 70 Parts by weight of deionized water, 10 parts by weight of polyacrylate resin and 20 Parts by weight of alkylalkoxysilane and siloxane. With the first order, the means penetrates largely into the material and provides very high moisture protection, while the second job at least partially forms a surface protection. This means not only provides a high level of 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.
Der Anteil an Alkylalkoxysilan und -siloxan hydrophobiert in der Platte, das Polyacrylatharz konserviert die Plattenoberfläche gegen Verschmutzungen.The proportion of alkylalkoxysilane and siloxane in the plate hydrophobizes the Polyacrylate resin preserves the surface of the plate against dirt.
