Die Erfindung geht aus von einem thermisch isolierenden Schichtmaterial, das aus übereinandergeschichteten Metallfolien in Form von Blättern oder Bändern besteht, die jeweils durch nichtmetallische, dünne Zwischenschichten voneinander getrennt sind. SThe invention is based on a thermally insulating layer material, which consists of layers stacked on top of one another Metal foils in the form of sheets or strips, each of which is replaced by non-metallic, thin intermediate layers are separated from each other. S.
Die soeben genannten Isolationen eignen sich nicht für die Isolation von sehr hohen Temperaturen. The insulation just mentioned is not suitable for insulation at very high temperatures.
Die Aufgabe der Erfindung besteht demnach gegenüber diesem Bekannten darin, Schichtmaterialien der im ersten Absatz dieser Beschreibung genannten Art insoweit zu verbessern, daß sie auf einfache Weise für die erfolgreiche Isolation bei sehr hohen Temperaturen geeignet sind.The object of the invention is therefore compared to this known layer materials of the type mentioned in the first paragraph of this description to the extent that it is simple Way are suitable for successful insulation at very high temperatures.
Zur Lösung dieser Aufgabe ist vorgesehen, daß die Zwischenschichten aus zumindest an je einer der einander zugewandten Oberflächen der filmartig dünnen Metallfolien festhaftenden, kompakten Metalloxydfilmen bestehen.To solve this problem it is provided that the intermediate layers of at least one of the facing surfaces of the film-like thin metal foils firmly adhering, compact metal oxide films exist.
Als für die Aufgabenlösung vorteilhafte und för- ao derliche Weiterbildungen sind weitere Merkmale den am Schlüsse der Beschreibung angeführten Unteransprüchen 2 bis 7 zu entnehmen.Further features are the further features that are advantageous and promotional for the solution of the task Referring to the dependent claims 2 to 7 at the end of the description.
Durch die Erfindung wird so auf einfache Weise erreicht, daß das Schichtmaterial für die erfolgreiche Isolation bei sehr hohen Temperaturen besonders geeignet ist. Dies wird dadurch erreicht, daß auf Grund der Eigenschaften der Metalloxydschichten diese sich nur an einzelnen Punkten, nämlich den Spitzen der rauhen Oberflächen, berühren und so die Übertragungsfläche für die Wärmeübertragung durch Leitung auf ein ganz geringes Mindestmaß herabgesetzt wird. Dies ist auch noch gegeben, wenn eine Oxydschicht direkt mit einer blanken Metallschicht in Berührung steht. Auch dann ist die Berührung nur an den einzelnen Punkten der rauhen Oxydschicht gegeben, so daß auch in diesem Fall die Übertragungsfläche für die Wärmeleitung ganz erheblich herabgesetzt wird. Diese Wirkung ist so stark, daß die durch die Oxydierung der Metallfolien praktisch außer Kraft gesetzte Isolation durch Spiegelung völlig unwesentlich wird, und durch die erhebliche Steigerung dieser Berührungsisolation weit mehr als ausgeglichen wird. Es wird auch noch insofern ein technischer Fortschritt durch die Erfindung erreicht, als die erheblich dünnen Metallfolien auch bei vielfacher Anordnung ein derartig geschmeidiges Isolationsmaterial ergeben, daß es nicht nur leicht z. B. auf einen rohrartigen Körper oder einen anderen zylindrischen Körper gewickelt werden kann, sondern daß es sich auch auf Grund seiner Geschmeidigkeit leicht an Oberflächen von zu iso-Thermisch isolierendes SchichtmaterialBy the invention is achieved in a simple manner that the layer material for the successful Isolation is particularly suitable at very high temperatures. This is achieved by on Due to the properties of the metal oxide layers, these are only found at individual points, namely the Tips of the rough surfaces, touch and so the transfer surface for the heat transfer is reduced to a very small minimum by management. This is still the case when an oxide layer is in direct contact with a bare metal layer. Even then is the touch only given at the individual points of the rough oxide layer, so that in this case too the transfer area for the heat conduction is reduced quite considerably. This is the effect strong, that the insulation practically disabled by the oxidation of the metal foils through Reflection becomes completely insignificant, and because of the considerable increase in this contact isolation far more than is compensated. Insofar as well, it becomes a technical advance by the invention than the considerably thin metal foils, even with multiple arrangements, it is so supple Insulation material show that it is not only easy z. B. on a tubular body or another cylindrical body can be wound, but that it is also due to its Slightly suppleness on surfaces of iso-thermal insulating layer material

Dadurch, daß bei der Erfindung Trennschichten mit sehr geringen, filmartig dünnen Dimensionen vorgesehen sind, ist es möglich, sehr viele solche Schichten in einer Isolation mit verhältnismäßig geringer Gesamtstärke unterzubringen, so daß hierbei das genannte Prinzip der punktförmigen Berührung der Metalloxydoberfläche mit der angrenzenden Schicht vielfach und damit vielfach erfolgreich und damit mit einem großen Gesamterfolg angewendet werden kann.The fact that in the invention separating layers with very small, thin, film-like dimensions are provided, it is possible to have very many such layers in one insulation with relatively less To accommodate total thickness, so that this is the principle of point-like contact mentioned the metal oxide surface with the adjoining layer many times and thus many times successfully and so that it can be applied with great overall success.

Aus der Zeichnung ist das thermisch isolierende Schichtmaterial zu ersehen. Es besteht aus übereinandergeschichteten Metallfolien 1 in Form von Blättern oder Bändern, die jeweils durch nichtmetallische, dünne Zwischenschichten 2 voneinander getrennt sind. Die Zwischenschichten 2 sind aus mindestens an je einer der einander zugewandten Oberflächen der filmartig dünnen Metallfolien 1 festhaftenden kompakten Metalloxydfilm gebildet.The thermally insulating layer material can be seen from the drawing. It consists of layered Metal foils 1 in the form of sheets or strips, each of which is replaced by non-metallic, thin intermediate layers 2 are separated from one another. The intermediate layers 2 are made of at least firmly adhering to one of the mutually facing surfaces of the film-like thin metal foils 1 compact metal oxide film is formed.

Die Zwischenschichten 2 können als Metalloxydfilme durch Oxydation des Metallfilmmaterials an der Oberfläche der Metallfolien 1 erzeugt sein.The intermediate layers 2 can be used as metal oxide films by oxidizing the metal film material on the Surface of the metal foils 1 be generated.
Jede der Metallfolien 1 kann auf mindestens einer Flächenseite einen Oxydfilm als Zwischenschicht 2 tragen.Each of the metal foils 1 can have an oxide film as an intermediate layer 2 on at least one surface side wear.
Das Schichtmaterial kann durch beiderseitig oxydierte Aluminium- oder Nickelfilme gebildet sein.The layer material can be formed by aluminum or nickel films that are oxidized on both sides.
Das Schichtmaterial kann durch Wickeln auf einen zu ilsolierenden Gegenstand gebracht werden oder es kann durch Aufdrücken auf einen Gegenstand mit unregelmäßig gestalteter Oberfläche gebracht werden.The layer material can be applied to an object to be insulated by winding or it can be applied to an object with an irregularly shaped surface by pressing it.
Die Metallfolien können auf pulvermetallurgischem Wege durch Sintern hergestellt sein.The metal foils can be produced by powder metallurgy by sintering.
Die Metallfolie 1 kann eine Stärke von 2/ioo bis 2/io mm haben.The metal foil 1 may have a thickness of 2 / ioo to 2 / io mm.
Fünf durch Fritten bzw. Sintern hergestellte Aluminiumfolien mit einer Ausgangsstärke von 120 bis 130 μ wurden anodisch auf ihren beiden Flächen oxydiert; die Stärke der Oxydfilme ist etwa 50 μ.Five aluminum foils produced by fritting or sintering with an initial thickness of 120 to 130 μ were anodically oxidized on both of their faces; the thickness of the oxide films is about 50 μ.
Das thermische Isolationsvermögen des Materials, das durch Aufeinanderschichten von fünf Folien erhalten wird, ist sehr gut, obwohl die gesamte Stärke des Materials außerordentlich klein ist (ungefähr 0,7 mm). Man sieht aus der graphischen Darstellung in Fig. 1, daß der Temperaturabfall in der Größenordnung von 300° C bei einem Druck von 1 kg/cm2 und von 200° C bei einem Druck von 25 kg/cm2 liegt.The thermal insulation capacity of the material, which is obtained by stacking five foils, is very good, although the total thickness of the material is extremely small (about 0.7 mm). It can be seen from the graph in FIG. 1 that the temperature drop is in the order of magnitude of 300 ° C. at a pressure of 1 kg / cm 2 and of 200 ° C. at a pressure of 25 kg / cm 2 .

Zehn Folien aus oxydiertem Aluminium, die in gleicher Weise hergestellt wurden wie im Beispiel I, werden übereinandergelegt; das Verbund-Isoliermaterial, das man auf diese Weise erhält, hat eine Stärke von ungefähr 1,5 mm. Aus der graphischen Darstellung der Fig. 1 erkennt man, daß dieses Material eine Isolierung darstellt, in der bei einem Druck von 1 kg/cm2 ein Temperaturabfall in der Größenordnung von 500° C und bei einem Druck von 25 kg/cm2 ein Temperaturabfall von etwa 350° C auftritt.Ten foils made of oxidized aluminum, which were produced in the same way as in Example I, are placed one on top of the other; the composite insulation material obtained in this way is approximately 1.5 mm thick. From the graph of FIG. 1 it can be seen that this material represents an insulation in which a temperature drop of the order of 500 ° C. at a pressure of 1 kg / cm 2 and a temperature drop at a pressure of 25 kg / cm 2 of about 350 ° C occurs.
