Description

Verfahren zur Herstellung eines Isolierstoffes Es ist bekannt, besonders hochwertige Isolierstoffe durch abwechselndes übereinanderschichten von Stoffen verschiedengradiger Isolier- oder Leitfähigkeit herzustellen. Die einzelnen Schichten derartiger Isolierstoffe; zum mindesten die der höheren Isolierfähigkeit, haben eine Dicke von weniger als o,oi mm. Besonders geeignet für die Herstellung solcher Schichten sind alle Lacke aus Leinöl oder Holzöl. Es hat sich herausgestellt, daß Isolierstoffe mit hochwertigen elektrischen Eigenschaften nur dann erhältlich sind, wenn die einzelnen dünnen Lackschichten bei sehr hoher Temperatur getrocknet werden.Process for producing an insulating material It is known in particular high-quality insulating materials through alternating layers of materials to produce different degrees of insulation or conductivity. The individual layers such insulating materials; at least those with a higher insulating capacity a thickness of less than 0.01 mm. Particularly suitable for making such Layers are all lacquers made from linseed oil or wood oil. It turned out that Insulating materials with high-quality electrical properties are only available when the individual thin layers of lacquer are dried at a very high temperature.

Als Träger für diese Lackschichten sind wegen ihrer günstigen mechanischen Eigenschaften Faserstoffbahnen, wie Papier oder Gewebe, sehr vorteilhaft; sie würden jedoch, wenn man sie den notwendigen Brenntemperaturen aussetzt, zerstört werden.As a carrier for these layers of paint are because of their favorable mechanical Properties of fibrous webs, such as paper or fabric, are very advantageous; they would however, if they are exposed to the necessary firing temperatures, they will be destroyed.

Nach der Erfindung wird daher vorgeschlagen, die Lackschichten zunächst ohne Träger nach beliebigem Verfahren herzustellen und diese nach dem Brennen bei hoher Temperatur unter Anwendung eines Bindemittels mit der Faserstoffbahn zu vereinigen. Als Bindemittel kann auch der zur Herstellung der isolierenden Schicht verwendete Lack benutzt werden.According to the invention, it is therefore proposed that the lacquer layers be applied first without producing a carrier by any process and after firing to combine high temperature using a binder with the fibrous web. The binder used to produce the insulating layer can also be used as a binder Paint can be used.

Es ist nicht wesentlich, daß eine geschlossene Schicht des gesondert hergestellten Lackfilmes aufgebracht wird. Man kann auch ähnlich der Herstellung von Glimmerstücken oder Glimmerpapieren den Lackfilm schuppenförmig übereinandergelegt auf den Träger aufbringen.It is not essential to have a closed layer of the separately produced paint film is applied. One can also similar the manufacture From pieces of mica or mica paper, the lacquer film is laid on top of one another in a flaky manner Apply to the carrier.
