Der Schutz der metallischen Verstärkungseinlagen in technischen Gummi- und Kunststoffartikeln gegen korrosive Angriffe der Außenatrnosphäre ist ein Problems das sich unter den verschiedensten Voraussetzungen und Bedingungen immer wieder von neuem bietet und trotz weitreichender Aufwendungen in Einzelfällen nicht immer befriedigende Lösungen findet, Die Vorstellung eines vollkommenen Schutzes in dem umgebenden elastomeren Werkstoff hat in der Praxis keineswegs allgemeine Gültigkeit* Wenn es schon schwierig ist, eine vollständige s lückenlose Ummantelung der Einlagen mit ganzMchiger Haftung an dem elastomeren Werkstoff zu erreichen, so treten dazu als weitere Fehlerquelle mechanische Beschädigungen der aufgebrachten Deck-The protection of metallic reinforcing inserts in technical rubber and plastic articles against corrosive attacks Außenatrnosphäre is a problem s that under different terms and conditions lends itself over and over again, and despite extensive expenses in individual cases, not always satisfactory solutions found, the idea of a perfect protection in the surrounding elastomeric material is in practice by no means generally valid * If it is difficult to achieve a complete s seamless covering of the deposits with Ganzmchiger liability to the elastomeric material, as a further source of error mechanical damage to the applied cover

lagen unter dynamischer Beanspruchung der Artikel auf, wodurch eindringender Feuchtigkeit Wege geöffnet werden.. Die daraus entstehenden Korrosionaschäden bleiben aber nicht örtlich beschränkt, sondern sie wandern an den Einlagen entlang und je nach deren Beschaffenheit auch in diesen Über längere Strecken fort, so daß es ohne anfänglich überhaupt erkennbare äußere Auswirkungen zu Zerstörungen größeren Ausmaßes kommt« Besonders gefährdet sind in-: dieser Hinsicht Fördergurte mit eingebetteten Stahldrahtseilen oder -litzen als den die Längskräfte aufnehmenden Festigkeit st rägern. Die als Folge ihres Aufbaues aus einer Vielzahl von Einzeldrähten vorgegebene vergleichsweise lockere Struktur der Seile mit stark zerklüfteter Oberfläche und bis in den Kern sich hindurchziehenden Hohlräumen macht das als ade al angestrebte vollständige;, geschlossene Umhüllen mit haftender Bindung an den elastomeren Werkstoff mit den bekannten Techniken vor allem in den obere.n Größenklassen unmöglich. Es hat zwar nicht an Versuchen gefehlt, ein gründliches "Durchbinden" des Gummis oder Kunststoffes in die Seele beispielsweise durch vorheriges Imprägnieren der Drahtseile mit Gummilösung, Ummanteln einzelner Drähte oder Litzen mit noch plastischer Mischungj Einfügen einer plastischen Komponente schon' beim Schlagen der Seile uea,ia. zu erzielen. Über Teilerfolge kamen alle Bemühungen in dieser Richtung aber nicht hinaus«were under dynamic stress of the article on, whereby penetrating moisture paths are opened .. The resulting corrosion damage but not locally limited, but they migrate along the deposits and depending on their nature in these over longer distances, so that it without initially noticeable external effects lead to large-scale destruction "In this respect, conveyor belts with embedded steel wire ropes or strands are more endangered than the strength carriers which absorb the longitudinal forces. The comparatively loose structure of the ropes with a strongly fissured surface and the cavities extending into the core as a result of their construction makes the complete, closed sheath with adhesive bonding to the elastomeric material known in the art with the known techniques especially in the upper size classes impossible. There has been no lack of attempts, a thorough "Durchbinden" the rubber or plastic in the soul, for example, by previously impregnating the wire with rubber solution, sheathing individual wires or strands with even plastic Gemischj inserting a plastic component already 'when hitting the ropes u e a, Ia. to achieve. Partial successes did not push all efforts in this direction. "

Darlegung des Wesens der ErfindungExplanation of the essence of the invention
Der Erfindung liegt demgemäß als Aufgabe zugrundes einen Schichtkörper zu schaffen, wobei die metallischen Einlagen 'in dynamisch beanspruchten Gummi- und Kunststoffartikeln unter Wahrung ihrer stoffschlüssigen Bidjnung an den Einbettungswerkstoff wirksam und dauerhaft gegen korrosive Einflüsse der Außenatmosphäre, in erster Linie gegen das Eindringen von Feuchtigkeit geschützt sind. Wenn dieses Problem auch vor allem für sogenannte Stahlseil-Fördergurte "und Kraftübertragungsriemen mit in Längsrichtung durchlaufenden Drahtseilen oder ähnlichen fadenförmigen metallischen Festigkeitsträgern besondere Bedeutung hat, so ist die Erfindung in weitem Umfange auch auf andere technisch eingesetzte biegsame Schichtkörper anwendbar.The invention is accordingly an object to provide s a stacked body, wherein the metallic inserts' in dynamically loaded rubber and plastic articles while maintaining their cohesive Bidjnung to the embedding material effectively and permanently against corrosive influences of the outer atmosphere, primarily against the ingress of moisture are protected. Although this problem is particularly important for so-called steel cable conveyor belts "and power transmission belt with longitudinally passing through wire ropes or similar filamentary metallic reinforcements, the invention is widely applicable to other technically used flexible laminates.
Zur Lösung der Aufgabe ist nunmehr ein Schichtkörper.vorgesehen, der sich dadurch auszeichnet, daß die mindestens in Teilbereichen ihrer Oberfläche stoffschlüssig mit dem umgebenden elastomeren Werkstoff verbundenen metallischen Einlagen mit einem auf der Grundlage eines Besti^adteils einer elastomeren Werkstoffmischung allgemein oder der für den jeweils vorliegenden Schichtkörper verwendeten spezifischen Mischung, vorzugsweise eines Verarbeitungshilfsmittels oder/und eines Weichmachers, aufgebauten fließfähi- gen Korrosionsschutzmittel überzogen sind. Je nach der Art und Beschaffenheit des Einbettungswerkstoffes kann das Korrosionsschutzmittel z«, B, auf einem paraffin- oder naphtenbasiachen Mineralöl, einem Chlorparaffin oder einer flüssigen organischen Ester- oder Ätherverbindung od. dgl» aufgebaut sein» Auf jeden Fall ist die Basis so auszuwählen, daß das Schutzmittel im Endeffekt ausgeprägt wasserabweisende Bestandteile enthält«,To achieve the object, a Schichtkörper.vorgesehen now, which is characterized in that the at least in some areas of its surface cohesively connected to the surrounding elastomeric material metallic deposits with a on the basis of Besti adum an elastomeric material mixture in general or for each coating composition used herein, preferably a processing aid and / or a plasticizer, built flowable corrosion inhibitor coated.

Flüssige Korrosionsschutzuiittel zum oberflächlichen Behandeln frei gespannter oder in sonstwie exponierter Anordnung verwendeter Zugseile sind an sich bekannt. Im Rahmen der vorliegenden Problemstellung kam der Gebrauch solcher in der Regel auf Öl-, Wachs- oder Vaseline-Basis aufgebauter handelsüblicher Schutzmittel von vornherein nicht in Betracht, weil daraus schwerwiegende Beeinträchtigungen der Haftverbindung zu erwarten waren» Der entgegen allen Erfahrungen der Praxis erfindungsgemäß eingeschlagene neuartige Lösungsweg über die Vorbehandlung der Einiagenelemente führte zu überraschend günstigen Ergebnissen, die sich in einer wesentlich verminderten Korrosionsanfälligkeit und einer gleichzeitig verbessert-to dynamischen Tüchtigkeit der Einlagen zeigten und die auch unter den harten Biege-Wechsel-Beanspruchungen z„ B„ eines Stahlseil-Fördergurtes im Dauerversuch Bestand hatten» Die Ursache hierfür setzt sich wahrscheinlich aus dem Zusammentreffen mehrerer jeweils für sich allein schon wichtiger Einzeleffekte zusammen: Einmal ist es der elastomeren Werkstoffmischung möglich, in ihrer Fließphase vor dem Vernetzen tief zwischen die Einzeldrähte einzudringen. Zum anderen sind auch die feinsten verbleibenden Hohlräume mit einem wasserabweisenden Mittel angefüllt, das gleichzeitig als Schmiermittel die unmittelbare metallische Gleitreibung innerhalb der Seile unterbindet, und schließlich bildet der ohne Rücksicht auf ihre Oberflächengestalt die Drahtseile geschlossen umgebende Überzug einen zuverlässigen Schutz gegen die durch Risse und andere Schadstellen im Einbettungswerkstoff eindringende Feuchtigkeit* Als zusätzlicher Vorteil ist die schon vor dem Verarbeiten der Einlagenelemente gegebene Schutzwirkung zu werten»Liquid anticorrosive agents for the superficial treatment of freely tensioned or otherwise exposed arrangement Zugseile are known per se. In the context of the present problem, the use of such usually based on oil, wax or petrolatum commercially available protective agents from the outset was out of the question, because it severe deterioration of the bonding were to be expected »The contrary to all the experience of the practice inventively embarked novel Solution over the pretreatment of Einiagenelemente led to surprisingly favorable results, which showed in a much reduced susceptibility to corrosion and at the same time improved-to dynamic efficiency of the deposits and even under the hard bending-alternating stresses z "B" of a steel cable conveyor belt Endurance test had a stock »The reason for this probably consists of the combination of several individual effects, each of which is important in and of itself: Once it is possible for the elastomeric material mixture to be deep in its flow phase before it is crosslinked to penetrate between the individual wires. On the other hand, even the finest remaining cavities are filled with a water-repellent agent, which at the same time inhibits the direct metallic sliding friction within the ropes as a lubricant, and finally, regardless of their surface shape, the wire ropes closed coating forms a reliable protection against cracking and other Damage in the embedded material moisture penetrating * As an additional advantage, the protective effect already given prior to the processing of the insert elements should be evaluated »
