Metallbleche zeigen wegen ihrer guten Wärmeleitfähigkeit ein ungünstiges Verhalten bei Einwirkung von Hitze oder Brand. Sie werden schnell über Rotglut erhitzt und stellen daher für die Ausbreitung eines Brandes ein geringes Hindernis dar.Metal sheets show because of their good thermal conductivity unfavorable behavior when exposed to heat or fire. They get red hot quickly heated and therefore represent a minor obstacle to the spread of a fire.
Es ist bekannt, Bleche oder aus Blechen verfertigte Konstruktionselemente mit isolierenden Anstrichen zu versehen. Bei längerer Hitzeeinwirkung werden diese Anstriche jedoch infolge ungleichmäßiger Wärmeausdehnung rissig, so daß isolierende Wirkung verlorengeht.It is known to use sheet metal or construction elements made of sheet metal with insulating paints to provide. With prolonged exposure to heat, however, these coatings become more uneven as a result Thermal expansion cracked, so that the insulating effect is lost.
Es ist ferner bekannt, für den Oberflächenschutz von massiven Metallen oder für dünne metallische Aufdampfungsschichten auf diesen Silikatschichten aus Wasserglaslösungen aufzubringen. Diese Schichten können auch als Isolierschichten auf Transformatorenkernen oder Kondensatorfolien aufgebracht werden. Zur Erhöhung der Haftfestigkeit dieser Schichten auf den Metalloberflächen gibt man den Wasserglaslösungen Metallsalze, insbesondere Schwermetallsalze, zu. Die Aufbringung dieser Schichten erfolgt durch Tauchen, Aufstreichen oder Spritzen. Die Schichten werden dann bei erhöhten Temperaturen getrocknet. Es gelingt auf diese Weise, in einem Arbeitsgang nur dünne Schichten aufzutragen. Zwecks Herstellung von dickeren Schichten müssen die obengenannten Arbeitsgänge mehrmals wiederholt werden. Diese Schichten vermögen jedoch das darunterliegende Metall nicht gegen den Einfluß von Hitze zu schützen.It is also known for the surface protection of solid metals or for thin metallic ones To apply vapor-deposition layers on these silicate layers from water glass solutions. These layers can also be applied as insulating layers on transformer cores or capacitor foils will. To increase the adhesive strength of these layers on the metal surfaces, one gives metal salts, especially heavy metal salts, to the waterglass solutions. The application of this Laying is done by dipping, brushing or spraying. The layers are then increased at Temperatures dried. In this way, it is possible to apply only thin layers in one operation. In order to produce thicker layers, the above-mentioned operations must be repeated several times be repeated. However, these layers cannot counteract the influence of the underlying metal protect from heat.
Es sind auch feuerfeste Isoliermaterialien bekannt, die aus Schaumvermiculit, einem faserigen Verstärkungsmittel und einem Bindemittel bestehen. Das Bindemittel besteht ganz oder zum größten Teil aus aufbereiteter Fullererde in der Form von synthetischem Natriummontmorillonit, in welchem das Calcium der natürlich modifizierten Fullerde durch Natrium ersetzt ist.There are also known refractory insulating materials made from foam vermiculite, a fibrous reinforcing agent and a binder. The binder consists entirely or for the most part processed fuller's earth in the form of synthetic sodium montmorillonite, in which the calcium the naturally modified full earth is replaced by sodium.
Bekannte Werkstoffe mit hoher Zugfestigkeit enthalten neben Glasfasern ein mineralisches Bindemittel, wobei als Bindemittel Zement, Gips, Magnesia, Anhydrit, Kalk usw. in Betracht kommen.Known materials with high tensile strength contain a mineral binder in addition to glass fibers, cement, gypsum, magnesia, anhydrite, lime, etc., come into consideration as binders.
Zur Herstellung eines Emailleüberzuges werden auf die Oberflächen von Gegenständen Wasserglaslösungen, die pulverisierten Asbest enthalten, aufgebracht und die so aufgebrachten Schichten anschließend hohen Temperaturen ausgesetzt.To produce an enamel coating, water glass solutions, containing powdered asbestos, applied and then the layers applied in this way exposed to high temperatures.

Es wurde gefunden, daß man wänneisolierende, mit Alkalisilikaten kombinierte Bleche auf einfache Weise herstellen kann, wenn man eine faser- und wasserhaltige Alkalisilikatplatte ein- oder beidseitig mit einem Blech oder ein Blech beidseitig mit einer faser- und wasserhaltigen Alkalisilikatplatte abdeckt und das so erhaltene Plattenpaket bei Temperaturen von 50 bis 150° C, vorzugsweise 80 bis 120° C, verpreßt. x It has been found that heat-insulating sheets combined with alkali silicates can be produced in a simple manner if a fibrous and water-containing alkali silicate board is covered on one or both sides with a sheet or a sheet is covered on both sides with a fiber and water-containing alkali silicate board and the board package obtained in this way at temperatures of 50 to 150 ° C, preferably 80 to 120 ° C, pressed. x
Die Bleche können diskontinuierlich oder auch kontinuierlich in der Weise hergestellt werden, daß man das Blech und die Brandschutzplatte zwischen zwei geheizten gleichlaufenden Rollenpaaren unter Druck durchlaufen läßt.The sheets can be produced discontinuously or continuously in such a way that the sheet metal and the fire protection plate between two heated pairs of rollers running at the same time Pressure can go through.
Die erfindungsgemäß hergestellten Bleche lassen sich ohne weiteres auf den bei der Metallverarbeitung üblichen Tiefziehmaschinen zu Formkörpern verarbeiten, wobei die Verarbeitung bei erhöhten Temperaturen, bei denen die Brandschutzplatten plastisch werden, aber noch nicht schäumen, vorgenommen wird. Dies ist bei Temperaturen von 50 bis 150° C, vorzugsweise von 80 bis 120° C, der Fall. Ein mit einer Brandschutzplatte, die, bezogen auf wasserfreies Alkalisilikat, einen Wassergehalt vonThe sheets produced according to the invention can easily be used in metal processing customary deep-drawing machines to process moldings, the processing at increased Temperatures at which the fire protection panels become plastic but do not yet foam will. This is the case at temperatures from 50 to 150.degree. C., preferably from 80 to 120.degree. One with a fire protection plate, which, based on anhydrous alkali silicate, has a water content of

Die nicht mit einer Brandschutzplatte abgedeckte Seite des Bleches, kann ohne Schwierigkeiten mit einem üblichen" Einbrennlack versehen werden. Zweckmäßig verwendet man Lacke, die bei Temperaturen um 100 bis 120° C eingebrannt werden, da bei höheren Temperaturen die Brandschutzplatte zu schäumen beginnt.The side of the sheet that is not covered with a fire protection plate can be used without difficulty a customary "stoving lacquer. It is expedient to use lacquers which are at temperatures around 100 to 120 ° C, as the fire protection panel closes at higher temperatures foaming begins.
