Description

Verfahren zur Beschleunigung der Vulkanisation von natürlichem oder künstlichem Kautschuk oder kautschukartigen Substanzen. Die Erfindung schließt sich an das Beschleunigungsverfahren bei der Vulkanisation von Kautschuk u. dgl. an, welches Gegenstand des Patents 323688 ist. Wie im Falle des Hauptpatents wird auch hier bezweckt, den gewünschten Vülkanisationsvorgang in einer kürzeren Zeit zu vollenden, als wie es nach dem gewöhnlichen Arbeitsverfahren möglich ist, während gleichwohl ein richtig vulkanisiertes Produkt erhalten wird. Gemäß der Erfindung wird dem Kautschuk oder der kautschukähnlichen Masse vor der @ Vulkanisation neben Schwefel eine kleine Menge Nitrosophenol oder seiner Homologen, wie beispielsweise Nitrosokresole oder Nitrosoxylenole, hinzugefügt.Process for accelerating the vulcanization of natural or artificial rubber or rubber-like substances. The invention follows on from the acceleration method in the vulcanization of rubber and the like, which is the subject of patent 323688. As in the case of the main patent, the aim here too is to complete the desired vulcanization process in a shorter time than is possible with the usual working method, while at the same time obtaining a properly vulcanized product. According to the invention, a small amount of nitrosophenol or its homologues, such as, for example, nitrosocresols or nitrosoxylenols, is added to the rubber or the rubber-like mass before the vulcanization.

Durch den Zusatz irgendeiner dieser Substanzen, der in einem proportionellen Verhältnis zur Kautschukmischung zu nehmen ist, und darauffolgende.Behandlung der Mischung bei Vulkanisiertemperatur nach irgendeinem zweckdienlichen Verfahren wird ein richtig durchvulkanisiertes Produkt in einer erheblich kürzeren Zeit als mittels des bisher gebräuchlichen Vulkanisierungsverfahren ohne Beifügung des Beschleunigers erhalten.By adding any of these substances, in a proportional Ratio to the rubber compound is to be taken, and subsequent treatment of the Mixture at vulcanization temperature by any convenient method a properly vulcanized product in a considerably shorter time than by means of the vulcanization process commonly used up to now without adding the accelerator obtain.

Das Verfahren wird an folgenden Beispielen erläutert. Eine Mischun-- aus xoo Gewichtsteilen Plantagen-Kautschuk, xö - Schwefel, x - Nitrosophenol wird auf 135 ° C während. go bis 35 Minuten erhitzt. In dieser Zeit ist die Yulkanisation vollständig beendet.The process is illustrated by the following examples. A mix-off xoo parts by weight of plantation rubber, xö - sulfur, x - nitrosophenol is maintained at 135 ° C during. go heated to 35 minutes. During this time the vulcanization is completely finished.

Würde der Zusatz des Beschleunigungsmittels nicht angewendet, so dauert die Zeit der Vulkanisation ungefähr eine Stunde. Eine Verkürzung der Vulkanisationsdauer wird auch erzielt, wenn der Plantagen-Kautschuk durch Para- oder irgendeinen anderen natürlichen Gummi oder durch . künstlichen Kautschuk ersetzt wird.If the addition of the accelerating agent was not used, it would take a long time the time of vulcanization about an hour. A shortening of the vulcanization time is also obtained when the plantation rubber is made by Para- or any other natural rubber or through. artificial rubber is replaced.

Die oben angegebenen Mengenverhältnisse sind nur beispielsweise angeführt. Die Erfindung - ist nicht an die Innehaltung derart bestimmter Verhältnisse gebunden.The proportions given above are only given by way of example. The invention - is not tied to maintaining such specific relationships.
