  Isoliermaterial, bestehend aus abwechselnden Schichten von Papier und Glimmer, die unter
Verwendung eines Bindemittels unter Wärme und Druck miteinander vereinigt sind. 



   Die Zeichnung zeigt das den Gegenstand der   Erfindung bildende Isolielmaterial,   das aus abwechselnden Schichten von Papier   a und Glimmer b besteht,   die in bekannter Weise unter Anwendung von Wärme und Druck miteinander vereinigt werden. Der Neuerung gemäss besteht das Bindemittel aus einem Gemisch von natürlichem und Kunstharz. 



   Die Isolierhülsen für die   Wicklung von Hot-hspannungsmaschinen werden in   der Regel aus Glimmer und Papier hergestellt, beide unter Anwendung von Wärme und Druck durch natürliches Harz, wie Schellack, vereinigt. In neuerer Zeit hat man mit grossem 
 EMI1.1 
 Rücksicht auf das günstige Verhalten dieses Materials bei Temperatursteigerungen. Dieses
Kunstharz hat sich nun bei Isoliermaterialien, die lediglich aus Papier bestanden, unter den verschiedensten Verhältnissen bewährt, jedoch haben sich Schwierigkeiten ergeben, sobald man bei den üblichen Röhren oder Platten aus Glimmerpräparaten diese Kunstharze verwenden wollte. Es ergab sich   nämlich,   dass das Material insbesondere bei dünnen
Schichten ausserordentlich   spröde war   und dass die Klebekraft für die dünnen Glimmerplättchen nicht ausreichte. 



   Es ist nun vorgeschlagen worden, die   Glimmerplättchen   zunächst durch natürliches Harz zu binden und sie dann unter Verwendung von Kunstharz mit Papier zu vereinigen. Dies bedingt jedoch ein umständliches Arbeitsverfahren insofern, als zwei   Arbeitsgänge   mit verschiedenem Material erforderlich sind. 



   Der Erfindung gemäss kann nun dieser Arbeitsvorgang vereinfacht werden und die Vorzüge des natürlichen Harzes mit denen des Kunstharzes vereinigt werden, indem man zur Herstellung von Glimmermaterialien, die aus Papier und Glimmer bestehen, und die unter Verwendung von Wärme und Druck miteinander vereinigt werden, als Bindemittel ein Gemisch von natürlichem und Kunstharz verwendet. Das natürliche Harz erhöht dann die Klebekraft und Elastizität des Endproduktes, während das Kunstharz die Temperatur-   beständigkeit   und die   vorzüglichen elektrischen Eigenschaften   des Gesamtmaterials liefert.

  Insulating material consisting of alternating layers of paper and mica covering the underneath
Using a binder under heat and pressure are combined.



   The drawing shows the insulating material forming the subject of the invention, which consists of alternating layers of paper a and mica b, which are combined with one another in a known manner using heat and pressure. According to the innovation, the binding agent consists of a mixture of natural and synthetic resin.



   The insulating sleeves for the winding of hot-voltage machines are usually made of mica and paper, both combined with the application of heat and pressure by a natural resin such as shellac. In recent times one has with great
 EMI1.1
 Consideration of the favorable behavior of this material in case of temperature increases. This
Synthetic resin has now proven itself in insulating materials that consisted only of paper under a wide variety of conditions, but difficulties have arisen as soon as one wanted to use these synthetic resins in the usual tubes or plates made from mica preparations. It was found that the material is particularly thin
Layers was extremely brittle and that the adhesive strength was insufficient for the thin mica flakes.



   It has now been proposed to first bind the mica flakes with natural resin and then to combine them with paper using synthetic resin. However, this requires a cumbersome working process in that two operations with different materials are required.



   According to the invention, this process can now be simplified and the advantages of the natural resin can be combined with those of the synthetic resin by using as binders for the production of mica materials which consist of paper and mica and which are combined with one another using heat and pressure uses a mixture of natural and synthetic resin. The natural resin then increases the adhesive force and elasticity of the end product, while the synthetic resin provides the temperature resistance and the excellent electrical properties of the entire material.
