Description

Verfahren zur Beschleunigung der Vulkanisation von natürlichen oder künstlichen Kautschukarten. Es wurde gefunden, daß das Amid der Ameisensäure, das Formamid. einen wertvollen Beschleuniger bei der Vulkanisation von natürlichen oder künstlichen Kautschukarten darstellt. Es hat den Vorzug der völligen Ungiftigkeit und des Fehlens von Ätzwirkungen. Die mit Hilfe dieses Produktes hergestellten Vulkanisate besitzen eine vorzügliche Dehnungsfähigkeit.Method of accelerating the vulcanization of natural or artificial rubbers. It has been found that the amide of formic acid, the Formamide. a valuable accelerator in the vulcanization of natural or represents artificial rubbers. It has the advantage of being completely non-toxic and the lack of caustic effects. The vulcanizates produced with the help of this product have excellent elasticity.

Bei seiner Verwendung empfiehlt sich ein gleichzeitiger Zusatz von Zinkoxyd, wodurch eine wesentliche Aktivierung des Formainids erzielt wird.When using it, it is recommended to add at the same time Zinc oxide, whereby a substantial activation of the formainide is achieved.

Beispiel i.Example i.

ioo Gewichtsteile Rohkautschulz (smoked sheets), io Gewichtsteile Zinkweiß, 5 Gewichtsteile Schwefel, 1,5 Gewichtsteile Formarnid werden 5o Minuten bei 14o° vulkanisiert. Es entsteht ein Vulkanisat von hohen Zerreißwerten.100 parts by weight of smoked sheets, 10 parts by weight Zinc white, 5 parts by weight of sulfur, 1.5 parts by weight of formamide are 50 minutes vulcanized at 14o °. The result is a vulcanizate with high tear values.

Beispiel a.Example a.

ioo Gewichtsteile Rohkautschuk (smoked slieets ), i o Gewichtsteile Zinkweiß. 6 Gewichtsteile Schwefel, i Gewichtsteil Formamid werden 6o Minuten bei i4o° vulkanisiert. Das Vulkanisat zeigt sehr gute mechanische Eigenschaften.100 parts by weight of raw rubber (smoked slieets), 10 parts by weight Zinc white. 6 parts by weight of sulfur, 1 part by weight of formamide are at 60 minutes i4o ° vulcanized. The vulcanizate shows very good mechanical properties.
