Description

Verfahren zur Herstellung von Kautschukmischungen Es ist in der Kautschukindustrie allgemein üblich, in Kautschukmischungen gewisse Vulkanisationsbeschleuniger durch Zinkoxyd zu aktivieren und zur Erreichung einer Höchstwirkung noch i bis a % Stearinsäure zur Mischung zuzusetzen.Process for the production of rubber mixtures It is common practice in the rubber industry to activate certain vulcanization accelerators in rubber mixtures with zinc oxide and to add 1 to a% stearic acid to the mixture to achieve maximum effectiveness.

Man ist seit geraumer Zeit bemüht, die Stearinsäure durch andere die Aktivierung der Beschleuniger in gleicher Weise herbeiführende Stoffe zu ersetzen.Efforts have been made for some time to replace stearic acid with others Activation of the accelerator in the same way to replace inducing substances.

Es wurde nun gefunden, daß es möglich ist, die aktivierende Wirkung der Beschleuniger in gleicher Weise zu erreichen, wenn man an Stelle der Stearinsäure den Mischungen rohe oder gereinigte Montansäure oder deren Abkömmlinge, z. B. Montanwachs, zugibt. Hierbei genügt eine Zugabe von 2 bis 3 °/o zur üblichen Migchung. Es zeigte sich überdies, da13 die physikalischen Eigenschaften der so erhaltenen Vulkanisate gegenüber mit Stearinsäure erhaltenen eine merkliche Verbesserung aufweisen.It has now been found that it is possible to have the activating effect the accelerator can be achieved in the same way if one takes the place of stearic acid the mixtures of crude or purified montanic acid or its derivatives, e.g. B. montan wax, admits. An addition of 2 to 3% of the usual amount is sufficient. It showed In addition, the physical properties of the vulcanizates obtained in this way change show a marked improvement over those obtained with stearic acid.
