Description

Verfahren zur Herstellung von Gummilösungen. Im Hauptpatent 411539" wurde gezeigt, daß geringwertige Lösungsmittel für Kautschuk, wie Trichloräthylen, hochvisköse homogene Lösungen ergeben, und daß die bisher üblichen stärkeren Lösungsmittel, wie Benzin usw., Quellungen von erhöhter Plastizität liefern, wenn man Ester mehrwertiger Alkohole zufügt.Process for the production of rubber solutions. In the main patent 411539 " it has been shown that low-grade solvents for rubber, such as trichlorethylene, result in highly viscous homogeneous solutions, and that the previously common stronger solvents, like gasoline, etc., swellings of increased plasticity when one has polyvalent esters Adds alcohols.

Überraschenderweise wurde nun gefunden, daß als weitere inerte organische Körper an Stelle obiger Ester oder gemeinsam mit ihnen die Schwefeladditionsprodukte der Terpene mit gleichem Erfolge angewendet werden können. Man erhält solche z. B. in bekannter Weise als weniger visköse, hochviskose, teigartige oder feste Produkte, wenn man Terpentinöl mit Schwefel erhitzt.Surprisingly, it has now been found that as a further inert organic Body in place of the above esters or together with them the sulfur addition products the terpenes can be used with equal success. One receives such z. B. in a known manner as less viscous, highly viscous, dough-like or solid products, when you heat turpentine oil with sulfur.

Beispiel 1.Example 1.

i kg Rohgummi wird mit 12 kg Benzin und 20 g des obigen Schwefeladditionsprodukts gelöst und 4. kg Trichloräthylen binzugefügt.1 kg of raw rubber is mixed with 12 kg of gasoline and 20 g of the above sulfur addition product dissolved and added 4 kg of trichlorethylene.

Beispiel e.Example e.

i kg ungewalzter Rohgummi, 5 g Terpenkörper, 15 kg Benzin oder 25 kg Trichloräthylen.i kg of unrolled raw rubber, 5 g of terpene solids, 15 kg of gasoline or 25 kg of trichlorethylene.

Man kann in gleicher Weise nur Benzin oder nurTrichloräthylen oder andere Lösungsmittel bzw. Mischungen derselben in bekannten Mengenverhältnissen anwenden.In the same way you can only use gasoline or only trichlorethylene or other solvents or mixtures thereof in known proportions use.

PATENTANSPRUCH: Verfahren zur Herstellung von Gummilösungen nach Patent 411539, dadurch gekennzeichnet, daß man vor, während oder nach dem Lösen des Rohgummis in seinem Lösungsmittel Schwefeladdition sprodukte der Terpene gleichzeitig mit den Estern der mehrsäurigen Alkohole oder ohne dieselben zufügt. PATENT CLAIM: Process for the production of rubber solutions according to patent 411539, characterized in that sulfur addition products of the terpenes are added simultaneously with the esters of the polyacid alcohols or without them before, during or after dissolving the raw rubber in its solvent.
