Description

Die Erfindung betrifft eine aufspritzbare, anorganische Fasern und Bindemittel enthaltende Masse für Schall-, Wärme- und Feuerschutzisolationen, wie sie beispielsweise zur Isolation von Stahlbauteilen und sonstigen Konstruktionselementen verwendet werden. The invention relates to a sprayable composition for inorganic fibers and binders containing Sound, heat and fire insulation, such as those used for the insulation of steel components and other construction elements are used.

Derartige Isoliermassen werden als trockene Mischung in eine Aufspritzvorrichtung eingegeben und nach dem Austritt aus der Spritzdüse mit einem Wassernebel befeuchtet, so daß sich eine feuchte Masse bildet, die auf die zu schützende Oberfläche aufgespritzt wird. Trotz des Wassernebels läßt sich mit den bekannten Isoliermassen die Staubildung nicht ganz verhindern.Such insulating compounds are introduced into a spraying device as a dry mixture and after emerging from the spray nozzle moistened with a water mist, so that a moist mass forms, which is sprayed onto the surface to be protected. Despite the water mist, the known insulating compounds do not completely prevent the formation of congestion.

Aufgabe der Erfindung ist es, durch Zusetzen von öl eine Isoliermasse zu schaffen, die sich ohne Staubildung verarbeiten läßt.The object of the invention is to create an insulating compound by adding oil that can be removed without the formation of congestion can be processed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Isoliermasse etwa 5-20 Gew.% öl, bezogen auf das Gewicht der Bindemittel, zugesetzt wird. Um eine gute Staubbindung zu erreichen, empfiehlt es sich, die zerkleinerten «nd aufgelockerten anorganischen Fasern vor dem Mischen mit den Bindemitteln mit 10 bis 20% der zuzusetzenden Gesamtölmenge zu befeuchten und den Rest des ölzusatzes erst beim Mischen mit den Bindemitteln der Masse beizugeben. Damit sich währenddes Vermischens der Masse keine Klumpen bilden, wird das der Masse zuzusetzende öl den anorganischen Fasern und den Bindemitteln in fein zerstäubtem Zustand zugegeben. Versuche haben ergeben, daß dünnflüssige und geruchfreie oder gerucharme Mineralöle als ölzusatz besonders geeignet sind.According to the invention, this object is achieved in that the insulating compound is based on about 5-20% by weight of oil based on the weight of the binder. To achieve a good dust binding, recommends the chopped up and loosened inorganic fibers before mixing with the binders to be moistened with 10 to 20% of the total amount of oil to be added and the rest of the oil addition only when Mix with the binders to add to the mass. So that no Form lumps, the oil to be added to the mass becomes the inorganic fibers and binders in added in a finely atomized state. Tests have shown that thin and odorless or Low-odor mineral oils are particularly suitable as oil additives.

Als Bindemittel können hydraulisch wirkende Bindemittel, z. B. Portlandzement, Tonerdezement, Schlackenzement usw. und auch chemische Bindemittel, wie Phosphatbinder, Alkalimetalle und andere geeignete Metallverbindungen verwendet werden.As binders, hydraulically acting binders such. B. Portland cement, high alumina cement, Slag cement etc. and also chemical binders such as phosphate binders, alkali metals and other suitable ones Metal compounds are used.

Die Menge des zuzusetzenden Öles ist abhängig von der Zusammensetzung der Bindemittel, die ihrerseits davon abhängig sind, ob die Isoliermasse als Schalldämmung oder als Wärme- bzw. Feuerschutzisolierung verwendet werden soll.The amount of oil to be added depends on the composition of the binder, which in turn depend on whether the insulation material is used as sound insulation or as heat or fire protection insulation should be used.

Nachstehend ist die Erfindung an Hand einiger Ausführungsbeispiele beschrieben:The invention is described below using a few exemplary embodiments:

Bei den vorgenannten Mischungen werden die anorganischen Fasern, z. B. Steinwolle, zuerst auf 3 bis 30 mm Länge zerkleinert und aufgelockert. Gleichzeitig werden die anorganischen Fasern mit etwa 10 bis 20% der zuzusetzenden Gesamtölmenge angefeuchtet. Das öl wird in fein zerstäubtem Zustand auf die anorganischen Fasern gesprüht, die sich in einer Mischvorrichtung befinden. Anschließend werden die Bindemittel in die Mischvorrichtung eingefüllt und unter allmählicher Zugabe des restlichen Öles mit den anorganischen Fasern vermischt. Die zuzusetzende ölmenge ist von den zur Anwendung kommenden bo Bindemitteln abhängig. So muß beispielsweise bei Bindemitteln mit hohem Tonerdegehalt mehr öl zugesetzt werden. Die auf diese Weise hergestellte Isoliermasse ist beim Verspritzen mit einer Druckluftspritzmaschine, deren Mundstück mit einer öenetfai zungsvorrichtung versehen ist, völlig staubfrei.In the aforementioned mixtures, the inorganic fibers, e.g. B. rock wool, first on 3 to 30 mm length chopped up and loosened. At the same time, the inorganic fibers with about 10 Moistened up to 20% of the total amount of oil to be added. The oil comes in a finely atomized state sprayed the inorganic fibers that are in a mixer. Then the Binder filled into the mixer and with the gradual addition of the remaining oil with the inorganic fibers mixed. The amount of oil to be added depends on the one used bo binders dependent. For example, binders with a high alumina content require more oil to be added will. The insulating compound produced in this way is, when spraying with a compressed air spraying machine, whose mouthpiece is provided with an opening device, completely dust-free.
