Description

Verfahren zur Herstellung von Kautschukerzeugnissen Es ist bekannt, Kautschuk in Mischung mit solchen Zinkoxyden zu vulkanisieren, die aus auf dem Fällungswege gewonnenen Zinkverbindungen unterhalb der Glühtemperatur gewonnen sind.Process for the production of rubber products It is known Vulcanize rubber in a mixture with such zinc oxides, which are made by precipitation obtained zinc compounds are obtained below the annealing temperature.

Es wurde gefunden, daß man nach diesem Verfahren Erzeugnisse von besonders hoher mechanischer Widerstandsfähigkeit erhält, wenn man ein Zinkoxyd verwendet, welches eine geringe Menge, zweckmäßig zwischen i bis 6 0;o, Aluminiumoxyd enthält.It has been found that this process produces products of particularly good quality high mechanical resistance is obtained when using a zinc oxide, which contains a small amount, expediently between 1 and 6 0; o, aluminum oxide.

Stellt man' z. B. ein Zinkoxyd mit einem Gehalt von 2 0;o Aluminiumoxyd in der Weise her, daß man eine mit dem entsprechenden Zusatz von Aluminiumchlorid versehene Zinkchloridlösung mittels Natriumcarbonats fällt, den Niederschlag trocknet und bei q00° calciniert, und vulkanisiert i oo Teile Kautschuk mit 15 Teilen eines solchen Oxyds, ¢ Teilen Schwefel, 2 Teilen eines unter dem Namen Kautschol im Handel befindlichen Braunkohlenteerproduktes und i Teil Diphenylguanidin während ¢5 Minuten bei 3 Atm., so ist die Zerreißfestigkeit des Vulkanisats um etwa 20 %, die Strukturfestigkeit nahezu um das Doppelte höher als diejenige eines in sonst genau gleicher Weise, aber unter Verwendung eines von Aluminiumoxyd freien Zinkoxyds hergestellten Produktes. Zur Erzielung gleicher Festigkeiten braucht man von dem aluminiumoxydhaltigen Zinkoxyd erheblich geringere Mengen zuzusetzen als von dem bekannten.If you put 'z. B. a zinc oxide with a content of 2 0; o aluminum oxide in such a way that a zinc chloride solution provided with the appropriate addition of aluminum chloride is precipitated using sodium carbonate, the precipitate is dried and calcined at q00 °, and 100 parts of rubber are vulcanized with 15 Parts of such an oxide, ¢ parts of sulfur, 2 parts of a lignite tar product sold under the name Kautschol and 1 part of diphenylguanidine for ¢ 5 minutes at 3 atm., The tensile strength of the vulcanizate is about 20%, the structural strength almost twice higher than that of a product made in exactly the same way, but using a zinc oxide free from aluminum oxide. In order to achieve the same strengths, considerably smaller amounts of the aluminum oxide-containing zinc oxide have to be added than of the known one.
