  Verfahren zur Herstellung einer schwofelfrelen, elastischen Masse.

 zu Produkten, die bei den hohen, für die Vulkanisation notwendigen Temperaturen ganz oder teilweise flüssig werden, weshalb sie nur in luftdicht geschlossenen Apparaten vulkanisiert und deshalb bei vielen Fabrikaten nicht angewendet werden können. 
 EMI1.2 
 wie Kautschuk vulkanisiert werden kann und auch bei den höchsten, beim Vulkanisieren angewandten Temperaturen nicht einmal teilweise flüssig wird. Das Verfahren zur Herstellung dieser elastischen Masse ist das folgende :
Eine fettsaure Metallverbindung, z. B. Aluminium-Stearat, Eisenpalmitat. Kalziumoder Magnesium-Stearat oder Palmitat, entweder für sich oder in einem hochsiedenden Kohlen-   wasserstoffgemenge, z.   B. Ozokerit, gelöst, wird in ein auf hohe Temperatur, z.

   B.   250"C erhitztes     trocknendes     01, z. B.   Leinöl, eingebracht, welches   vorher während längerer Zeit erhitzt gewesen   ist und mit einem der bekannten Oxydationsmittel, z. B. Mangandioxyd, behandelt wurde. 



  Durch diesen Zusatz wird eine zähe, elastische Masse erhalten, welche mit den pulverförmigen

   Die Verwendung von fettsauren Metallverbindungen für die Herstellung   schwefelfreier,   elastischer Massen ist schon früher vorgeschlagen, wie z. B. in dem D. R. P. Nr. 147688 und 190817. 



   In der Masse nach dem D. R. P. Nr. 147688 werden zwar fettsaure Metallsalze verwendet. jedoch ungesättigte Fettsäure ausdrücklich ausgeschlossen und die Einverleibung dieser Salze

 to products that become completely or partially liquid at the high temperatures required for vulcanization, which is why they are only vulcanized in airtight apparatus and therefore cannot be used with many makes.
 EMI1.2
 how rubber can be vulcanized and does not even become partially liquid even at the highest temperatures used in vulcanization. The method for making this elastic mass is as follows:
A fatty metal compound, e.g. B. aluminum stearate, iron palmitate. Calcium or magnesium stearate or palmitate, either on its own or in a high-boiling hydrocarbon mixture, e.g. B. ozokerite, dissolved, is in a high temperature, z.

   B. 250 "C heated drying oil, e.g. linseed oil, is introduced, which has previously been heated for a long time and has been treated with one of the known oxidizing agents, e.g. manganese dioxide.



  By this addition a tough, elastic mass is obtained, which with the powdery
 EMI1.3
   the mass can be vulcanized using pressure and heat like rubber.



   The use of fatty acid metal compounds for the production of sulfur-free, elastic masses has been proposed earlier, such. B. in D. R. P. Nos. 147688 and 190817.



   In the composition according to D.R.P. No. 147688, fatty acid metal salts are used. however, unsaturated fatty acids and the incorporation of these salts are expressly excluded
