Description

Verfahren zum Vulkanisieren von Kautschuk mit Chlorschwefeldampf In der Kautschukindustrie ist bei der Heißvulkanisation mit Schwefel die Verwendung von Beschleunigern bekannt. Es sind dies meist organische Verbindungen verschiedener Zusammensetzung, die die Eigenschaft besitzen, den Vulkanisationsprozeß in der Wärme außerordentlich zu beschleunigen. Ein wirklich wirksamer Beschleuniger für die Kaltvulkanisation mit Chlorschwefeldampf war bisher nicht bekannt. Ein solcher wurde im Titandioxyd gefunden, von dem kleine Mengen die Vulkanisation außerordentlich beschleunigen, und zwar genügt zur Vulkanisation nur ein Bruchteil der Zeit, die ohne Titandioxyd notwendig ist. Die Vulkanisation wird ganz wie bisher durchgeführt, nur daß die Vulkanisationsdauer auf wenige Minuten beschränkt wird.Process for vulcanizing rubber with sulfurous chloride vapor In The rubber industry is used for hot vulcanization with sulfur known from accelerators. These are mostly organic compounds of various types Composition that have the property of the vulcanization process in the heat to accelerate extraordinarily. A really effective accelerator for cold vulcanization with chlorine sulfur vapor was not previously known. Such was found in titanium dioxide found, of which small amounts accelerate the vulcanization extraordinarily, Vulcanization takes only a fraction of the time without titanium dioxide necessary is. The vulcanization is carried out exactly as before, only that the Vulcanization time is limited to a few minutes.

Ausführungsbeispiel: HelleHevea-Crepes werden mit 6% Titandioxyd 2o Minuten auf der Mischmaschine gemischt und in Benzin (2o Gewichtsteile Mischung in ioo Gewichtsteilen Benzin) gelöst. Die aus dieser Lösung durch Tauchen hergestellten Gegenstände werden mit Schwefelchlorürdampf (1,5 ccm S. C12 für einen Raum von rund 3o 1) in 2 Minuten vulkanisiert. Eine gleich hergestellte, titandioxydfreie Kautschukmischung braucht zum Vulkanisieren etwa 40 Minuten.Exemplary embodiment: HelleHevea crepes are made with 6% titanium dioxide 2o Minutes on the mixer and mixed in gasoline (2o parts by weight of the mixture dissolved in 100 parts by weight of gasoline). Those made from this solution by dipping Objects are filled with sulfuric chloride vapor (1.5 ccm S. C12 for a space of around 3o 1) vulcanized in 2 minutes. A similarly produced, titanium dioxide-free rubber mixture takes about 40 minutes to vulcanize.
