Description

Verfahren zur Herstellung haltbarer Verbindungen zwischen vulkanisierten und zu vulkanisierenden Schichten von Mischpolymerisaten aus Butadien und Acrylsäurenitril Es war bisher unmöglich, auf vulkanisierte Mischpolymerisate aus Butadien und Acrylsäurenitril (im folgenden kurz als M bezeichnet) rohe M-Mischungen haltbar aufzuvulkanisieren oder auch zwei vulkanisierte WI-Schichten auf dem Wege der Vulkanisation miteinander haltbar zu verbinden, so wie es z. B. bei der Fabrikation oder der Reparatur von Autoluftschläuchen notwendig ist.Process for making durable joints between vulcanized and layers of copolymers of butadiene and acrylonitrile to be vulcanized It was previously impossible to rely on vulcanized copolymers of butadiene and acrylonitrile (hereinafter referred to as M for short) vulcanize raw M mixes in a durable manner or two vulcanized WI layers on the way of vulcanization with each other to connect durable, as it is z. B. in the manufacture or repair of Car air hoses is necessary.

Mittels des folgenden Verfahrens ist es jedoch möglich, die genannten Arbeitsgänge durchzuführen, und zwar ähnlich, wie sie auch bei der Verbindung von Naturkautschuk ausgeführt werden.However, it is possible to use the following procedure to achieve the above Perform operations similar to those used when connecting Natural rubber.

Das mit der rohen M-Schicht zu verbindende M-Vulkanisat wird sorgfältig und gut aufgerauht und mit einer am besten heißen Steinkohlenteerölfraktion mit einem Siedepunkt über 16o° C abgewaschen. Auf die so vorbereitete Verbindungsstelle wird nun unvulkanisierte M-Mischung gebracht, der ebenfalls Steinkohlenteeröldestillat beigemischt ist. Auf die unvulkanisierte M-Mischung kann nun noch zwecks Verbindung zweier vulkanisierter M-Schichten eine vulkanisierte M-Mischung gelegt werden, die, wie oben beschrieben, aufgerauht und mit Steinkohlenteeröl behandelt wurde. Durch entsprechendes Vulkanisieren der so vorbereiteten Stücke in der Presse wird die endgültige Verbindung erzielt.The M vulcanizate to be bonded with the raw M layer is carefully and well roughened and with a hot coal tar oil fraction a boiling point above 160 ° C washed off. On the joint prepared in this way Uncured M-Mixture is now brought, which is also coal tar oil distillate is mixed in. The unvulcanized M-mixture can now be used for the purpose of connection two vulcanized M-layers a vulcanized M-mixture are placed, which, as described above, roughened and treated with coal tar oil. By appropriate vulcanization of the prepared pieces in the press is the final connection achieved.
