Mit Festigkeitsträgern von Transportbändern in Verbindung stehende Gummimischung Rubber compound associated with reinforcement of conveyor belts

Die Erfindung betrifft eine unmittelbar mit textlien Feetigkeitsträgern von Förderbändern in Verbindung stehende Gummimischung.The invention relates to a rubber mixture that is directly connected to the textile feet of conveyor belts.

Zur Herstellung von Transportbändern mit Gewebeeinlagen bedarf es zunächst einer Vorbehandlung des Gewebes mit einer Haftlösung, was z.B. im Tauchprozeß vollzogen werden kann. Alsdann erfolgt ein Skimmen oder Friktionieren des Gewebes mit einer Haftmischung, und nachdem das Gewebe so vorbereitet ist, müssen die Deckgummierungen und Zwischenschichten aufgelegt werden.To manufacture conveyor belts with fabric inserts, the fabric must first be pretreated with an adhesive solution, which can be done, for example, in the immersion process. Then If the tissue is skimmed or frictionized with an adhesive mixture, and after the tissue has been prepared in this way, must the top rubber linings and intermediate layers are applied.

Somit werden mehrere Gummimischungen und dementsprechend viele Verfahrensschritte bei der Herstellung erforderlich.This means that several rubber compounds and, accordingly, many process steps are required during production.

Der Erfindung liegt im wesentlichen die Aufgabe zugrunde, die Herstellung von Transportbändern mit Gewebeeinlagen zu vereinfachen, und zwar für sogenannte flammwidrige Gewebetraneport, bänder.The invention is essentially based on the object of simplifying the production of conveyor belts with fabric inserts, specifically for so-called flame-retardant fabric tranport, tapes.

Die Erfindung geht von der Erkenntnis aus, daß diese Aufgabe besonders einfach dann zu lösen ist, wenn es gelingt, der Deckplattenmischung die erforderlichen Haftungseigenschaften zu verleihen, ohne dabei auf die üblichen Haftmittelzusätze und die vorgenannten Verfahrensschritte zurückgreifen zu müssen. Zugleich sollen jedoch die guten mechanischen Eigenschaften und das brandtechnische Verhalten nicht nachteilig beeinflußt werden.The invention is based on the knowledge that this problem can be solved particularly easily if it is possible to mix the cover plates the necessary adhesion properties without having to resort to the usual adhesive additives and the aforementioned process steps. At the same time, however, the good mechanical properties and the fire behavior should not be adversely affected will.

Zur Lösung dieser Aufgabe weist erfindungsgemäß die Gummimischung 5 bis 50 % auf das Basispolymer bezogen chloriertes Polyäthylen mit einem Chlorgehalt von 28 bis ^8 % auf.To achieve this object, according to the invention, the rubber mixture has 5 to 50 %, based on the base polymer, of chlorinated polyethylene with a chlorine content of 28 to 8 % .
