Aufgabenstellungtask
Ausgehend davon liegt der Erfindung die Aufgabe zugrunde, ein beschichtetes Mineralwolleprodukt anzugeben, dessen Beschichtung ohne einen mechanischen Eingriff in das Gefüge der Platte erfolgt, wobei die Trocknungszeit verkürzt, die Herstellungs- und Rohstoffkosten gesenkt werden und die Griffigkeit bei Verwendung als Putzträgerplatte erhalten bleiben soll.outgoing One of the objects of the invention is a coated one Mineral wool product whose coating without a mechanical Intervention in the structure the plate takes place, the drying time is shortened, the Production and raw material costs are lowered and the grip when used as a plaster base plate should be preserved.
Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale der Ansprüche 1 und 4.The solution This object is achieved by the characterizing features of claims 1 and 4th
Insbesondere ist eine Beschichtung aus einer aufgeschäumten und nach Verteilung auf der Plattenoberfläche ausgehärteten Beschichtungsmasse gebildet, wobei die Beschichtung die Diffusionsoffenheit und Oberflächenstruktur der Mineralwolle beibehält. Dadurch, dass die Beschichtungsmasse vor ihrem Auftrag in einer Schäummaschine oder mit einem Rührwerk derart aufgeschäumt wird, dass sich das Volumen der Mischung z. B. verfünffacht, wird einerseits erreicht, dass z. B. mit einem Rakel sämtliche oberflächennahen Fasern des Mineralwolleproduktes vollkommen benetzt werden und andererseits, dass der Massenanteil der Beschichtung wesentlich reduziert werden kann, was sich auf die Kosten sehr wesentlich auswirkt und vor allem auf die Einstufung in eine günstigere Brandklasse. Gleichzeitig wird die Oberfläche des Mineralwolleproduktes durch den Rakelvorgang mechanisch nicht beeinträchtigt, so dass zwar eine dünne, jedoch nahezu geschlossene einwandfreie Beschichtung erhalten wird.Especially is a coating of a foamed and after distribution on the plate surface cured Coating formed, wherein the coating is the diffusion-open and surface structure the mineral wool maintains. Due to the fact that the coating composition in a Foaming machine or with a stirrer frothed like that is that the volume of the mixture z. B. quintuplet, On the one hand achieved that z. B. with a squeegee all shallow Fibers of the mineral wool product are completely wetted and on the other hand, the mass fraction of the coating is substantially reduced can, which has a very significant impact on costs and, above all, on the classification in a cheaper Fire class. At the same time, the surface of the mineral wool product becomes mechanically not affected by the doctoring process, so that although a thin, but almost closed perfect coating is obtained.
Ausführungsbeispielembodiment
Als
Beispiel für
eine geeignete Beschichtungsmasse sei folgende Rezeptur genannt:
42
Gew: % Kieselsol (40 Gew: % Feststoffanteil SIO2)
13,5
Gew:-% Aluminiumhydroxid
2,5 Gew: % Kunstharzdispersion
0,5
Gew: % Schäumungsmittel
0,1
Gew: % Stabilisator
Rest Wasser.As an example of a suitable coating composition, the following recipe is mentioned:
42% by weight silica sol (40% by weight solid content SIO 2 )
13.5% by weight of aluminum hydroxide
2.5% by weight of synthetic resin dispersion
0.5% by weight of foaming agent
0.1% by weight stabilizer
Rest of water.
Diese Beschichtungsmasse wurde mit Hilfe eines Rührwerkes aufgeschäumt und mit einem Rakel auf die Oberfläche einer Mineralwolleplatte aufgebracht. Anschließend wurde eine derart beschichtete Platte in einem Durchlaufofen kurz getrocknet. Während dieses Aushärtens löst sich die Schaumstruktur auf. Dabei erfolgt eine feine Verteilung der Beschichtungsmasse auf der Oberfläche der Mineralwolleplatte und dringt dabei in den nahen Oberflächenbereich der Platte ein und vernetzt die oberflächennahen Fasern untereinander. Die Oberflächenstruktur der Platte blieb dabei erhalten, was z. B. für eine spätere Putzhaftung sehr wesentlich ist.These The coating composition was foamed with the aid of a stirrer and with a squeegee on the surface applied to a mineral wool plate. Subsequently, such a coated plate briefly dried in a continuous oven. During this hardening dissolves the foam structure on. In this case, a fine distribution of Coating compound on the surface of the mineral wool plate and penetrates into the near surface area of the plate and network the near-surface Fibers among each other. The surface structure the plate was retained, which z. B. very much for a later cleaning liability is.
Insgesamt kann man also feststellen, dass der erfinderische Grundgedanke, Zusatzkomponenten, Beschichtungsmassen, Kleber usw., in einem aufgeschäumten Zustand zu verwenden, mit Sicherheit auch für weitere vorteilhafte Anwendungsfälle denkbar ist, z. B. für das Sanieren von hinterlüfteten Fassaden, bei denen Mineralwolleprodukte an ihrer Oberfläche mit dem Auftrag von einer vorgeschäumten Beschichtungsmasse stabilisiert werden sollen.All in all So you can say that the inventive idea, Additional components, coating compounds, adhesives, etc., in a foamed state to use, certainly conceivable for further advantageous applications is, for. For example the renovation of ventilated facades, where mineral wool products on their surface with the order of one prefoamed Coating mass to be stabilized.
