Description

  

  Verfahren zur Herstellung von Isolationsmaterial.    Es sind Isolationsmaterialien     bekannt,    die  aus     Kondensationsprodukten    von organischen  Verbindungen, z. B. Phenol mit Formalde  hyd, bestehen (Kunstharz). Aus diesen wer  den unter Hinzufügung von Füllstoffen, z. B.  Papier, Sägemehl     und        dergleichen,    durch  Pressen     unter    gleichzeitiger Einwirkung von  Wärme die gewünschten Teile hergestellt.  Derartige Isolationsstoffe besitzen jedoch im  allgemeinen sehr .grosse     dielektrische    Verluste,  so dass sie für die Hochfrequenztechnik nur  bedingt in Frage kommen.

   Zur Herabsetzung  der     dielektrischen    Verluste ist es bereits be  kannt geworden, als Füllstoff Quarzsand zu  verwenden. Die Verwendung eines derartigen       Füllstoffes    hat jedoch in     pressteohnischer    Hin  sicht Nachteile, indem die gepressten Materia  lien     infolge    der schlechten     Fliessbarkeit    des  Materials Hohlräume aufweisen. Insbeson  dere bei Gegenständen mit mehreren Absät  zen oder     ganten    wirkt     sich    dieses nachteilig  aus,     indem    das Material beim Pressen nicht  in alle Ecken der     Pressform    gelangt.

      Zur Vermeidung dieser Nachteile     wird     nach dem Verfahren .gemäss vorliegender Er  findung zur Herstellung von Isolationsmate  rial aus     hochmolekularen        Kondensations-          produkten    als Füllstoff reiner Quarz zuge  setzt, der durch Mahlen von aus dem       Schmelzfluss        erstarrtem    Quarz erhalten wurde.

    Durch diese Massnahme ist der     Nachteil    der  schlechten Fliessbarken beseitigt,     so,dass    auch  bei     Herstellung    von schwierigen Gegenstän  den eine einwandfreie Formgebung gewähr  leistet ist, da das Material beim Pressen in  alle Ecken und     ganten    der     Pressform    ein  fliesst.  



  Eine Mischung, die neben der guten     Fliess-          barkeit    auch besonders gute     mechanische    und  elektrische Eigenschaften zeigt, besteht aus  <B>78%</B> Quarz der genannten Art und 22       Phenol-Formaldehyd-Kondensationsprodukt.          Ein,    aus     einer    derartigen Mischung hergestell  tes Isolationsmaterial besitzt     eine    hohe  Schlag- und     Biegefestigkeit.         Als     Ausgangsprodukt    zur     Herstellung    des  Füllstoffes kann Quarzsand gewählt werden,  der geschmolzen und dann gemahlen wird.

    Besonders     vorteilhaft        wirken    sich jedoch die       erfindungsgemässen    Massnahmen dadurch aus,  dass als Ausgangsprodukt auch Gebrauchs  gegenstände aus reinem Quarz, z. B. Retorten,  Röhren und dergleichen,     verwendet    werden  können, die für andere Zwecke nicht mehr       verwendbar    sind. Diese Stoffe können sofort  nach dem Mahlen als Füllstoff     verwendet     werden.  



  Sollte sieh zeigen, dass die     ,gepresste    Sub  stanz in der     Pressform    festklebt, so kann die  ses durch Zusatz von geringen Mengen     Olein     beseitigt werden.



  Process for the production of insulation material. There are insulation materials known, which consist of condensation products of organic compounds, for. B. phenol with formaldehyde, exist (synthetic resin). From these who the with the addition of fillers such. B. paper, sawdust and the like, produced the desired parts by pressing with the simultaneous action of heat. However, such insulation materials generally have very large dielectric losses, so that they are only of limited use for high-frequency technology.

   To reduce the dielectric losses, it has already become known to use quartz sand as a filler. The use of such a filler, however, has disadvantages in relation to the pressing, in that the pressed materials have voids due to the poor flowability of the material. Especially in the case of objects with several paragraphs or ganten, this has a disadvantageous effect in that the material does not get into all corners of the mold during pressing.

      To avoid these disadvantages, according to the present invention for the production of insulation material from high molecular weight condensation products, pure quartz is added as filler, which was obtained by grinding quartz solidified from the melt flow.

    This measure eliminates the disadvantage of poor flowability, so that perfect shaping is guaranteed even when difficult objects are being produced, since the material flows into all corners of the mold during pressing.



  A mixture which, in addition to good flowability, also exhibits particularly good mechanical and electrical properties, consists of <B> 78% </B> quartz of the type mentioned and 22 phenol-formaldehyde condensation product. An insulation material made from such a mixture has high impact and flexural strength. Quartz sand, which is melted and then ground, can be selected as the starting product for the manufacture of the filler.

    However, the measures according to the invention have a particularly advantageous effect in that, as starting products, commodities made of pure quartz, e.g. B. retorts, tubes and the like can be used, which are no longer usable for other purposes. These substances can be used as fillers immediately after grinding.



  If you see that the pressed substance sticks in the mold, this can be eliminated by adding small amounts of olein.
