  Verfahren zur Herstellung   gummiisolierter   Leiter. 



   Mit Gummi zu isolierende Leiter, insbesondere Kupferleiter werden bei den bisher üblichen Vulkanisationsverfahren durch chemische Einwirkung freien Schwefels angegriffen und müssen daher vor Aufbringen der zu vulkanisierenden Gummihülle über dem Leitermaterial einen   Sehutzüberzug   erhalten. 



  Stärkere Leiter werden beispielsweise verzinkt, schwächere erhalten eine Umspinnung und erst darüber die Gummiisolation. Schwache Leiter, wie Leonische Fäden, leiden besonders unter der zerstörenden Wirkung des Schwefels ; die Schutzschicht unter der Gummiisolation macht aber die Leitung steifer und dicker. 



   Nach der Erfindung werden alle Schutzvorkehrungen für den Leiter dadurch vermieden, dass der unmittelbar auf den blanken Leiter aufgebrachte Gummi nur mit solchen Vulkanisationsmitteln behandelt wird, die den Schwefel nur in einer das Leitermaterial nicht angreifenden Form, z. B. chemisch gebunden, enthalten und ihn nur vorübergehend abspalten. 



   Als geeignete Vulkanisationsmittel wurden sogenannte Vulkanisationsbeschleuniger erkannt, 
 EMI1.1 
 Vulkanisationsmittel verwendet. Man weiss zwar schon von ihrer selbständigen Vulkanisationsfähigkeit ; es war aber bisher nicht bekannt, dass sie bei alleiniger Verwendung das Leitermaterial, wie Kupfer, nicht angreifen und die Schwefelvulkanisation für die Zwecke der Erfindung vorteilhaft ersetzen können. 



   Beispielsweise wird auf einen Leonischen Leiter unmittelbar die zu vulkanisierende Gummihülle ohne jeden selbständigen   Schwefelzusatz   aufgebracht und nur mit einem Vulkanisationsbeschleuniger von der Zusammensetzung   [RNCSjs X   (R = Alkyl, vorzugsweise   CH. X =   vorzugsweise S oder schwefelhältiges Radikal) vulkanisiert. Der Vulkanisationsbeschleuniger wird der Gummimischung wie jeder andere Füllstoff zugesetzt. Vulkanisationsbeschleuniger dieser Art sind im Handel beispielsweise unter der Bezeichnung Thiuram   [ (CH3) 2   N C   Sh S2   erhältlich.

   Es entsteht auf diese Weise eine vollwertig isolierte Leitung von kleinem   Aussendurchmesser, guter   Biegsamkeit und geringem Gewicht, wie sie nach dem bisherigen Isolierverfahren nicht in gleicher Güte hergestellt werden kann. Der Vulkanisationsbeschleuniger spaltet bei Vulkanisationstemperatur Schwefel in genügenden Ausmass ab, der aber während des Vulkanisationsvorganges wieder gebunden wird. Nach diesem erfindungsgemässen Verfahren gummiisolierte Leiter sind an dem Fehlen der Zwischenhülle und an der blanken praktisch unangegriffenen Leiteroberfläche kenntlich.

  Process for manufacturing rubber-insulated conductors.



   Conductors to be insulated with rubber, in particular copper conductors, are attacked by chemical action of free sulfur in the vulcanization processes that have been customary up to now and must therefore be given a protective cover over the conductor material before the rubber sheath to be vulcanized is applied.



  Stronger conductors are galvanized, for example, weaker ones are wrapped and only above the rubber insulation. Weak conductors, such as Leonean threads, suffer especially from the destructive effects of sulfur; the protective layer under the rubber insulation makes the cable stiffer and thicker.



   According to the invention, all protective measures for the conductor are avoided in that the rubber applied directly to the bare conductor is treated only with vulcanizing agents that only release the sulfur in a form that does not attack the conductor material, e.g. B. chemically bound, contain and split it off only temporarily.



   So-called vulcanization accelerators have been recognized as suitable vulcanizing agents,
 EMI1.1
 Vulcanizing agent used. One already knows of their independent vulcanization ability; However, it was not previously known that, when used alone, they cannot attack the conductor material, such as copper, and can advantageously replace sulfur vulcanization for the purposes of the invention.



   For example, the rubber cover to be vulcanized is applied directly to a Leonischer Leiter without any independent sulfur addition and vulcanized only with a vulcanization accelerator with the composition [RNCSjs X (R = alkyl, preferably CH. X = preferably S or sulfur-containing radical). The vulcanization accelerator is added to the rubber compound like any other filler. Vulcanization accelerators of this type are available commercially, for example under the name Thiuram [(CH3) 2 N C Sh S2.

   In this way, a fully insulated cable with a small outer diameter, good flexibility and low weight is created, which cannot be produced in the same quality using the previous insulation process. The vulcanization accelerator splits off sufficient sulfur at vulcanization temperature, but this is bound again during the vulcanization process. According to this inventive method, rubber-insulated conductors can be identified by the absence of the intermediate sheath and the bare, practically unaffected conductor surface.



   PATENT CLAIMS:
1. A method for producing rubber-insulated conductors, in particular low-power conductors, characterized in that the rubber applied directly to the bare conductor is treated with vulcanizing agents which only contain the sulfur in a form that does not attack the conductor material.
