  Verfahren zur Herstellung von isolierenden Formkörpern für elektrotechnische Zwecke. 



   Vorliegende Erfindung betrifft ein Verfahren zur Herstellung von isolierenden Formkörpern für elektrotechnische Zwecke, die im wesentlichen aus Asbest, Asphalt   (bezw.   Theer, Pech oder dergl.) und etwa für erforderlich erachteten weiteren Füllstoffen bestehen. An und für sich sind solche Körper seit sehr langer Zeit bekannt. Sie werden

 Es wird dabei die Menge des Asphalts so gering wie möglich genommen. 



   Vorliegende Erfindung betrifft nun ein Verfahren, um solche Körper in besonders einfacher und sicherer Weise herzustellen. Es besteht darin, dass als Ausgangsmaterial ein Pulver verwendet wird, dass durch Zerkleinerung einer eine innige Vereinigung von Asbest, Asphalt und dergleichen darstellenden Masse gewonnen wird. Das Pulver kann dabei auch relativ grobkörnig gewählt werden. Es wird für die weitere Behandlung dadurch vorbereitet, dass es mit einer ganz geringen Menge eines organischen, leicht verdampf-

 verliert. Die so erhaltene Masse kann leicht in Pressformen eingefüllt werden und lagert sich sehr gleichmässig in den Formen.

   Durch starken Druck wird dann das Pulver zu einer festen gleichmässigen Masse vereinigt, die gegebenenfalls unter   Krwannen   getrocknet wird, um das Verdampfen der zum Befeuchten dienenden organischen   Flüssigkeit   zu beschleunigen. 



   Die als Ausgangsmaterial dienende Asphalt-Asbest-Masse, die in zerkleinertem Zustande weiter behandelt wird, kann dabei in beliebiger Weise hergestellt werden, beispielsweise so, dass Asbest direkt mit Asphalt im heissen Zustande verknetet wird oder aber so, dass der Asphalt zunächst in einem flüchtigen Lösungsmittel gelöst, dann mit Asbest innig gemenge und hierauf getrocknet und gemahlen wird.

  Process for the production of insulating moldings for electrotechnical purposes.



   The present invention relates to a method for the production of insulating molded bodies for electrotechnical purposes, which essentially consist of asbestos, asphalt (or tar, pitch or the like) and any other fillers considered necessary. Such bodies have been known in and of themselves for a very long time. you will be
 EMI1.1
 The amount of asphalt is used as little as possible.



   The present invention now relates to a method for producing such bodies in a particularly simple and safe manner. It consists of using a powder as a starting material which is obtained by crushing a mass which is an intimate combination of asbestos, asphalt and the like. The powder can also be selected to be relatively coarse-grained. It is prepared for further treatment by adding a very small amount of an organic, easily evaporated
 EMI1.2
 loses. The mass obtained in this way can easily be poured into molds and is stored very evenly in the molds.

   The powder is then combined under high pressure to form a solid, uniform mass, which is optionally dried under pan in order to accelerate the evaporation of the organic liquid used for moistening.



   The asphalt-asbestos mass used as the starting material, which is further treated in the crushed state, can be produced in any way, for example so that asbestos is kneaded directly with asphalt in the hot state or in such a way that the asphalt is initially in a volatile state Solvent dissolved, then intimately mixed with asbestos and then dried and ground.

PATENT-ANSPRUCH : Verfahren zur Herstellung von isolierenden Formkörpern für elektrotechnische Zwecke, dadurch gekennzeichnet, dass Asbest mit einer möglichst geringen Menge Theer, Asphalt oder Pech innig \ ereinigt, und die so erhaltene Masse zerkleinert wird, worauf das Pulver mit einer so geringen Menge Phenol oder Benzin, Benzol oder einer anderen organischen, leicht verdampfbaren Flüssigkeit angefeuchtet wird, dass das Pulver seine pulverförmige Beschaffenheit nicht verliert, worauf das so angefeuchtete Pulver unter hohem Druck in die gewünschte Form gepresst wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the production of insulating moldings for electrotechnical purposes, characterized in that asbestos is intimately cleaned with the smallest possible amount of tar, asphalt or pitch, and the resulting mass is comminuted, whereupon the powder is mixed with such a small amount of phenol or gasoline, benzene or another organic, easily evaporable liquid is moistened so that the powder does not lose its powdery nature, whereupon the moistened powder is pressed into the desired shape under high pressure. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
