Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von PolyvinylcHorid-Textil-Schichtkörpern, vorzugsweise mit einem auf Zug beanspruchten Textilkern, insbesondere auf Förderbänder oder Treibriemen mit verbesserter Wärmebeständigkeit, insbesondere der Textilien.The invention relates to a method for producing polyvinyl chloride textile laminates, preferably with a textile core subject to tensile stress, in particular on conveyor belts or Driving belts with improved heat resistance, especially of textiles.
Bekannte Vorschläge zur Herstellung von Förderbändern oder Riemen sehen vor, daß die Polyvinylchlorid-Deckschichten unmittelbar auf dem Textilkern angeordnet werden. Bei diesen Vorschlägen kann die gegenseitige Haftung von Deckschichten und Textilkern durch vorherige Imprägnierung der Textilschichten oder Fäden mit ungelierten Polyvinylchloriddispersionen verbessert werden.Known proposals for the production of conveyor belts or belts provide that the polyvinyl chloride cover layers be placed directly on the textile core. In these proposals, the mutual adhesion of top layers and Textile core through prior impregnation of the textile layers or threads with ungelled polyvinyl chloride dispersions be improved.
Nach anderen Veröffentlichungen wurde vorgeschlagen, daß die Textilien vor ihrem Verbinden mit den Polyvinylchloridschichten mit Stoffen vorbehandelt werden, die die Bindefähigkeit der Textilien zum Polyvinylchlorid erhöhen. Dabei wurden unter anderem Gemische aus Vinylchlorid-Vinylacetat-Mischpolymeren unter Zusatz von Polyisocyanaten, Polyvinylchlorid und Dioctylphthalat und dessen Oxydationsprodukte sowie eine wässerige Paraffinwachsemulsion genannt. Auf Grund ihrer chemischen Zusammensetzung bildeten diese Stoffe jedoch keine Schutzschicht auf den Textilien.According to other publications it has been suggested that the textiles prior to joining them with the polyvinyl chloride layers are pretreated with substances that improve the binding capacity of the textiles Increase polyvinyl chloride. Among other things, mixtures of vinyl chloride-vinyl acetate copolymers were used with the addition of polyisocyanates, polyvinyl chloride and dioctyl phthalate and its oxidation products as well as an aqueous paraffin wax emulsion. Due to their chemical composition, however, these substances did not form Protective layer on the textiles.
Bei den bisher bekannten Schichtkörpern aus Polyvinylchlorid und Textilien trat bislang nämlich stets der Nachteil auf, daß die Textilien, insbesondere Gewebe aus Baumwolle oder Zellwolle bzw. Kunstseide, bei längerer Einwirkung erhöhter Temperatur, z. B. von Temperaturen bei etwa 160° C, beschädigt bzw. zerstört wurden. Diese Temperaturen sind jedoch bei der Herstellung sowie beim Endlosmachen und Reparieren von textilhaltigen Schichtkörpern aus Polyvinylchlorid erforderlich, um die Gelierung des Polyvinylchlorids zu bewirken. Bei der Gelierungstemperatur tritt eine Chlorwasserstoffabspaltung aus dem Polyvinylchlorid auf. Durch diese Spaltprodukte werden die Textilien angegriffen. Nach einem weiteren bekannten Verfahren wird als Polyvinylchloridstabilisator Bleicarbonat vorgeschlagen. Derartige Stabilisatoren, die Chlorwasserstoff unschädlich machen sollen, sind nicht in allen Fällen wirksam genug, um eine völlige Schädigung der Textilien zu vermeiden. Auch bei Verwendung von Bleicarbonat ließ sich die Bildung von schädlichen Salzsäuredämpfen nicht ausschließen.In the case of the laminated bodies made of polyvinyl chloride and textiles known to date, this has always occurred the disadvantage that the textiles, especially fabrics made of cotton or rayon or rayon, prolonged exposure to elevated temperature, e.g. B. from temperatures of around 160 ° C, damaged or were destroyed. However, these temperatures are in manufacture as well as infinite and repair of textile-containing laminates made of polyvinyl chloride are required to ensure the gelation of the polyvinyl chloride to effect. At the gelation temperature, hydrogen chloride is split off from the Polyvinyl chloride. The textiles are attacked by these decomposition products. After another known method is proposed as a polyvinyl chloride stabilizer lead carbonate. Such Stabilizers, which are supposed to render hydrogen chloride harmless, are not effective in all cases enough to avoid total damage to the textiles. Even when using lead carbonate the formation of harmful hydrochloric acid vapors could not be ruled out.
Die vorstehend geschilderten Schwierigkeiten überwindet die vorliegende Erfindung, indem sie vorsieht, daß man auf der Textilschicht eine gegenüber chlorwasserstoffhaltigen Spaltprodukten des Polyvinyl-Verfahren zur Herstellung von Polyvinylchlorid -Textil - SchichtkörpernThe present invention overcomes the difficulties outlined above by providing that there is one on the textile layer containing hydrogen chloride Fission products of the polyvinyl process for the production of polyvinyl chloride textile laminated bodies

Sowohl bei Anwesenheit einer beständigen Schutzschicht als auch durch das Vorhandensein einer Schicht, welche die Zersetzungsprodukte des Polyvinylchlorids absorbiert, ist eine Schonung des darunterliegenden Textilkerns gewährleistet. Chloride-resistant protective layer and / or a arranges these fission products chemically harmless protective layer. Both in presence a permanent protective layer as well as the presence of a layer which absorbs the decomposition products of the polyvinyl chloride is one Protection of the underlying textile core guaranteed.
Zweckmäßig enthält die Schutzschicht Substanzen, die sich mit den aus dem Polyvinylchlorid entstehenden Spaltprodukten umsetzen. Die Spaltprodukte gehen vorzugsweise mit diesen Zusätzen eine chemische Reaktion ein, wodurch sie in unschädliche Substanzen umgewandelt werden. Vorzugsweise wird man derartige Substanzen vermeiden, die außer oder an Stelle von Stabilisatoren in der Schutzschicht vorhanden sind.The protective layer expediently contains substances that interact with those arising from the polyvinyl chloride Implement fission products. The cleavage products are preferably chemical with these additives Reaction, as a result of which they are converted into harmless substances. Preferably will you avoid such substances that are present in the protective layer in addition to or instead of stabilizers are.
Die Schutzschicht kann mit Vorteil solche Substanzen enthalten, deren chemischer Aufbau demjenigen der im Schichtkörper befindlichen Textilien verwandt ist. Wenn die Textilien z. B. auf der Basis von Cellulose aufgebaut sind, z. B. in Form von Baumwolle, Rayon, Zellwolle od. dgl., so kann man als Zusätze in der Schutzschicht Polysaccharide verwenden.

Thereupon a layer in the composite body is to be present, cover plate made of a polyvinyl chloride mixture, which can rather be the plastic cover plate only stabilizers, but otherwise no protective structures, so that the resulting small amounts of chlorine contains hydrogen quantities applied to this tissue core directly from the they are surrounded and the laminated body produced in this way is absorbed at a temperature of 170 ° C, such as this once again gels,
has been proven by experiments. The last-mentioned after a heat treatment duration of 60 Mi embodiment with a single layer has the grooves at 170 ° C, the fabric still showed 95 to advantage that only 100% of its original strength in one operation, while one layer was applied to the textiles need not be prepared tissue a decrease in strength up to (see also Fig. 3). As a rule, however, you will point to 25 to 20% of the original value. Apply a special protective layer to the textiles in front of the specified times of heat treatment and on top of this a cover layer made of a polyvinyl are applied separately in practice during the repair and / or chloride mixture, because the protective layer is formed as a binding layer at the same time when the tapes or belts are made endless achieved.
