 und etwa   20   eines Alterungsschutzmittels zugesetzt werden. 



   Als Vulkanisator eignet sich besonders Schwefel in Form von feinstgemahlener Schwefelblüte. Als Beschleuniger kommt vorzugsweise Dibenzothiazyldisulfid und als Alterungsschutzmittel   N-Phenyl-N'-     cyclohexyl-p-phenylendiamin   zur Verwendung, das hervorragende   Alterungs- und Ermüdungsschutzwir-   kungen besitzt, hiebei aber auf die Vulkanisation ohne Einfluss bleibt. 



     Beispiel.   Auf Grund praktischer Versuche hat sich folgendes bestimmte Mischungsverhältnis der Bestandteile als besonders geeignet erwiesen :
35% Butadien-Acrylnitril-Polymerisat,
34%   Phenol-Formaldehyd-Novolac-Harz   mit Hexamethylentetramin modifiziert,   221o   gefällte Kieselsäure mit einem geringen Anteil an Calciumsilikat (weisser Russ),   91o   Eisenoxyd (gelb). 



   Hiezu kommen, jeweils bezogen auf den Anteil des Butadien-Acrylnitril-Polymerisats   50   (d. h. 1750 g bei 35 kg des synthetischen Kautschuks) feinstgemahlene Schwefelblüte,

 and about 20 of an anti-aging agent can be added.



   Sulfur in the form of finely ground sulfur blooms is particularly suitable as a vulcanizer. Dibenzothiazyl disulfide is preferably used as the accelerator and N-phenyl-N'-cyclohexyl-p-phenylenediamine is used as the anti-aging agent, which has excellent anti-aging and anti-fatigue properties but has no effect on vulcanization.



     Example. On the basis of practical tests, the following particular mixing ratio of the components has proven to be particularly suitable:
35% butadiene-acrylonitrile polymer,
34% phenol-formaldehyde novolac resin modified with hexamethylenetetramine, 221o precipitated silica with a small proportion of calcium silicate (white soot), 91o iron oxide (yellow).



   In addition, based in each case on the proportion of the butadiene-acrylonitrile polymer 50 (i.e. 1750 g for 35 kg of the synthetic rubber), finely ground sulfur flowers,
