Description

Verfahren zum Vulkanisieren von Kautschukwaren mit Phosphorsulfidlösungen. Die Erfindung betrifft ein Verfahren zum Vulkanisieren von Kautschukwaren mittels Phosphorsulfide und bezweckt die Anwendung dieser Mittel bei der Herstellung von getauchten Kautschukwaren, wasserdichten Geweben und geformten Kautschukgegenständen unmittelbar aus der Kautschuklösung. Erfindungsgemäß werden die Phospliorsulfide vor ihrer Anwendung in Schwefelkohlenstoff aufgelöst, der die Wirksamkeit dieser Stoffe als Vulkanisiermittel im wesentlich ,höheren Maße steigert als andere Lösungsmittel, wie Tetrahydronaphthalin, Te-'trachloräthan usw.Process for vulcanizing rubber goods with phosphorus sulfide solutions. The invention relates to a method for vulcanizing rubber goods by means of Phosphorus sulphides and aims to use these agents in the manufacture of dipped rubber goods, waterproof fabrics and molded rubber articles directly from the rubber solution. According to the invention, the phosphorus sulfides dissolved in carbon disulfide before use, which increases the effectiveness of this Substances as vulcanizing agents substantially, increases to a higher degree than other solvents, such as tetrahydronaphthalene, tetrachloroethane, etc.

Für das Vulkanisieren von getauchten Kautschukwaren wird die Form, welche mit Kautschuk durch Eintauchen in der üblichen Weise überzogen worden ist, in eine Lösung voti einem der Phosphorsulfide in Schwefelkohlenstoff eingetaucht oder vorzugsweise in eine Lösung in Schwefelkohlenstoff, welcher etwas mit Naphtha verdünnt wurde. Einige Minuten des Eintauchens genügen für die Bewirkung einer wirksamen Vulkanisierung.For the vulcanization of dipped rubber goods, the shape, which has been coated with rubber by dipping in the usual way, immersed in a solution of one of the phosphorus sulfides in carbon disulfide or preferably in a solution in carbon disulfide, which is something with naphtha has been diluted. A few minutes of immersion is enough to produce an effective one Vulcanization.

Fiir die Herstellung von wasserdichten Geweben wird die mit Kautschuk überzogene Fläche des Gewebes eine kurze Zeit der Ein-Wirkung einer Lösung von Phosphorsulfiden in Schwefelkohlenstoff oder mit Naphtha verdünntem Schwefelkohlenstoff ausesetzt, woz# durch die Kautschulzfläche vulkanisiert wird. Für die Herstellung von Formstücken immittelbar aus der Kautschuklösung wird eine Kautschuklösung von entsprechender Konzentration, z. B. eine ioprozentige Lösung von Kautschuk in Benzin, Naphtha, Schwefelkohlenstoff usw. oder Gemischen dieser Lösungsmittel, mit einem bestihnmten Prozentsatz einer Lösung von Phosphorsulfiden in Schwefelkohlenstoff gemischt. Nach einigem Umrühren wird das Gemisch in eine Form eingegossen und stehengesas@sen, bis sieh eine Gallerte gebildet hat. Die Gallerte wird dann aus der Form entfernt und das Lösungsmittel entweder durch mäßige Wärme oder durch Luft l:ei gewöhnlicher Temperatur verdampft.For the production of waterproof fabrics, rubber is used Coated area of the fabric a short time of exposure to a solution of phosphorus sulfides exposed to carbon disulfide or carbon disulfide diluted with naphtha, woz # is vulcanized by the Kautschulz surface. For the production of fittings Immediately from the rubber solution, a rubber solution of the corresponding Concentration, e.g. B. a 10% solution of rubber in gasoline, naphtha, Carbon disulfide, etc., or mixtures of these solvents, with a certain Percentage of a solution of phosphorus sulfides mixed in carbon disulfide. To the mixture is poured into a mold and left to stand, until it has formed a jelly. The jelly is then removed from the mold and the solvent either by moderate heat or by air, more commonly Temperature evaporates.
