Description

  

  Verfahren zur Isolierung elektrisch leitender Teile mittels Glasseide  und     Polyorganosiloxanen.            Als    temperaturbeständige Isolation für  elektrische Geräte wurde mit     Polyorgano-          siloxan    getränkte Glasseide vorgeschlagen. So  werden z.

   B. die Wicklungsdrähte     elektrischer     Maschinen mit Glasseide umsponnen, mit       Glasseidebändern    umwickelt und vor, besser  nach der     lIerstellung    der Wicklung mit ge  löstem, verhältnismässig stark polymerisier  tem     Polyorganosiloxan    getränkt: Die fertige       Maschine    wird dann in einem Trockenofen  zwecks Austreibung des Lösungsmittels und  Verfestigung des     Polyorganosiloxans    wärme  behandelt.  



  Es zeigt sich, dass dabei das     Polyorgano-          siloxan    sich nicht genügend fest. mit der  Glasseide verbindet und bei Lagerung in  feuchten Räumen trotz seiner     wasserabsto-          fienden    Eigenschaften nicht eine gewisse, die  Isolation     verschlechternde        Feuchtigkeitsauf-          ziahme    verhüten kann.  



  Die Erfindung geht von der Erkenntnis  aus dass an diesen Missständen die     Wasser-          haut    auf den Glasfäden schuld ist, die sich  sehr rasch unter dem Einfluss der Luft  feuchtigkeit bildet. Das erfindungsgemässe  Verfahren zur Isolierung elektrisch leitender  Teile mittels Glasseide und     Polyorgano-          siloxanen    ist dadurch gekennzeichnet, dass die  Glasseide sogleich nach dem Verspinnen mit  einer ein     Polyorganosiloxan    enthaltenden  Flüssigkeit behandelt Und hierauf zum Isolie  ren verwendet wird. Vorteilhaft wird eine       Polyorganosiloxan-Lösung    in einem wasser  freien Lösungsmittel verwendet.

   Besonders  günstig ist es, ein     flüssiges        Polyorganosiloxan       oder eine Lösung eines     Polyorganosiloxans     gleich als Schlichte beim Verspinnen der  Glasseide zu verwenden. Es empfiehlt sich,  die Herstellung und Verarbeitung der Glas  seide in Räumen mit getrockneter Luft vor  zunehmen.  



  Durch die Erfindung wird die     Glasseide-          Polyorganosiloxan-Isolation    elektrisch und  mechanisch wesentlich verbessert.



  Process for isolating electrically conductive parts using glass fiber and polyorganosiloxanes. Glass fiber impregnated with polyorganosiloxane has been proposed as temperature-resistant insulation for electrical devices. So z.

   B. the winding wires of electrical machines are spun with fiberglass, wrapped with fiberglass tapes and before, better after the winding is soaked with dissolved, relatively strongly polymerized polyorganosiloxane: The finished machine is then in a drying oven to expel the solvent and solidify the polyorganosiloxane heat treated.



  It turns out that the polyorganosiloxane is not sufficiently firm. connects to the fiberglass and, despite its water-repellent properties, cannot prevent a certain level of moisture absorption which can deteriorate the insulation when stored in damp rooms.



  The invention is based on the knowledge that the water skin on the glass threads is to blame for these deficiencies, which forms very quickly under the influence of air humidity. The inventive method for insulating electrically conductive parts by means of glass fiber and polyorganosiloxanes is characterized in that the glass fiber is treated with a liquid containing a polyorganosiloxane immediately after spinning and is then used for insulation. A polyorganosiloxane solution in an anhydrous solvent is advantageously used.

   It is particularly favorable to use a liquid polyorganosiloxane or a solution of a polyorganosiloxane as the size when spinning the glass fiber. It is advisable to manufacture and process the glass silk in rooms with dried air.



  With the invention, the glass fiber polyorganosiloxane insulation is significantly improved electrically and mechanically.
