Description

Continental Gummi-Werke Aktiengesellschaft, 3000 HannoverContinental Gummi-Werke Aktiengesellschaft, 3000 Hanover Schichtkörper, insbesondere Fördergurt oder AntriebsriemenLaminated body, in particular a conveyor belt or drive belt

Die Erfindung bezieht sich auf aus Gummi oder gummiähnlichen elastomeren Werkstoffen mit metallischen Verstärkungseinlagen hergestellte band- oder bahnförmige biegsame Schichtkörper, insbesondere «it i« wesentlichen in Längsrichtung durchlaufenden eingebetteten Stahldrahtseilen, -litzen od. dgl. verstärkte Fördergurte oder Antriebsriemen.The invention relates to elastomers made of rubber or rubber-like Materials with metallic reinforcement inserts made of strip or web-shaped flexible laminates, in particular "it i" embedded steel wire ropes running lengthways, -litz or the like. Reinforced conveyor belts or drive belts.

Der Schutz der metallischen Verstärkungseinlagen in technischen Gummi- und Kunststoffartikeln gegen korrosive Angriffe der Außenatmosphäre ist ein Problem, 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 ungebenden elastomeren Werkstoff hat in der Praxis keineswegs allgemeine Gültigkeit. Wenn es schon schwierig ist, eine vollständige, lückenlose Ummantelung der Einlagen mit ganzflächiger Haftung an dem elastomeren Werkstoff zu erreichen, so treten dazu als weitere Fehlerquelle mechanische Beschädigungen der aufgebrachten Decklagen unter dynamischer Beanspruchung der Artikel, wodurch eindringender Feuchtigkeit Wege geöffnet werden. Die daraus entstehenden Korrosionsschäden 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 -litsen als den die Längskräfte aufnehmenden Festigkeitsträgern. Die als Folge ihres Aufbaues aus einer Vielzahl von Einzeldrähten vorgegebene vergleichsweise lockere Struktur der Seile mit stark zerflüfteter Oberfläche und bis in den Kern sich hindurchziehenden Hohlräumen macht das als ideal angestrebte vollständige, geschlossene Umhüllen mit haftender Bindung an den elastomeren Werkstoff mit den bekannten TechnikenThe protection of the metallic reinforcement inserts in technical rubber and plastic articles against corrosive attacks from the outside atmosphere is a problem that presents itself again and again under the most varied of prerequisites and conditions and despite far-reaching ones Expenditure in individual cases does not always find satisfactory solutions. The idea of a perfect protection in the unbalanced In practice, elastomeric material is by no means generally applicable. If it is already difficult, a complete, gapless sheathing of the inserts with full-surface adhesion to the elastomeric material A further source of error is mechanical damage to the applied cover layers under dynamic stress the article, thereby opening the way for moisture to penetrate. However, the resulting corrosion damage does not remain locally restricted, but they migrate along the deposits and, depending on their nature, also in these over longer distances, so that there is extensive destruction without any visible external effects at first. Are particularly at risk in this Regarding conveyor belts with embedded steel wire ropes or lits than the reinforcements absorbing the longitudinal forces. The one given as a result of its structure from a large number of individual wires comparatively The loose structure of the ropes with a strongly tattered surface and hollow spaces that extend through to the core do this as ideally strived for complete, closed envelopes with adhesive bond to the elastomeric material with the known techniques

vor allem in den oberen 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 Bit noch plastischer Mischung, Einfügen einer plastischen Komponente schon beim Schlagen der Seile u.a.m. zu erzielen, über Teilerfolge kamen alle Bemühungen in dieser Richtung aber nicht hinaus.especially impossible in the upper size classes. It is not on There is no attempt to thoroughly "bind through" the rubber or plastic in the core, for example by impregnating the Wire ropes with rubber solution, sheathing of individual wires or strands, bit more plastic mixture, insertion of a plastic component already when hitting the ropes, etc., everyone came across partial successes Efforts in this direction, however, do not extend beyond this.

Der Erfindung liegt demgemäß als Aufgabe zugrunde, die metallischen Einlagen in dynamisch beanspruchten Gummi- und Kunststoffartikeln unter Wahrung ihrer stoffschlüssigen Bindung an den Einbettungswerkstoff wirksam und dauerhaft gegen korrosive Einflüsse der Außenatmosphäre, in erster Linie gegen das Eindringen von Feuchtigkeit zu schützen. 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 doch nicht ausschließlich hierauf beschränkt, sondern in weitem Umfange auch auf andere technisch eingesetzte biegsame Schichtkörper anwendbar.The invention is accordingly based on the object, the metallic Inserts in dynamically stressed rubber and plastic items under Preservation of their material bond to the embedding material to protect effectively and permanently against corrosive influences of the outside atmosphere, primarily against the ingress of moisture. if this problem especially for so-called steel cord conveyor belts and power transmission belts with wire ropes running in the longitudinal direction or similar thread-like metallic reinforcements has particular importance, the invention is not exclusively based on this limited, but also to a large extent to other technically used ones flexible laminates applicable.

Nach der Erfindung zeichnen sich Schichtkörper der eingangs geschilderten Gattung dadurch aus, daß die mindestens in Teilbereichen ihrer Oberfläche stoffschlüssig mit dem umgebenden elastomeren Werkstoff verbundenen metallischen Einlagen mit einem auf der Grundlage eines Bestandteile einer elastomeren Werkstoffmischung allgemein oder der für den jeweils vorliegenden Schichtkörper verwendeten spezifischen Mischung, vorzugsweise eines Verarbeitungshilfsmittels oder/und eines Weichmachers, aufgebauten fließfähigen Korrosionsschutzmittel überzogen sind. Je nach der Art und Beschaffenheit des Einbettungswerkstoffes kann das Korrosionsschutzmittel z.B. auf einem paraffin- oder naphtenbasischen Mineralöl, einem Chlorparaffin oder einer flüssigen organischen Ester- oder Ä'therverbindung od. dgl. aufgebaut sein. Auf jeden Fall ist die Basis so auszuwählen, daß das Schutzmittel im Endeffekt ausgeprägt wasserabweisende Bestandteile enthält.According to the invention, laminated bodies of those described at the outset stand out This genus is characterized in that the at least in partial areas of their surface cohesively connected to the surrounding elastomeric material metallic inserts with one based on a component of an elastomeric material mixture in general or for each present laminated body used specific mixture, preferably a processing aid and / or a plasticizer, built up flowable anti-corrosion agents are coated. Depending on the type and properties of the embedding material, the anti-corrosion agent e.g. on a paraffin or naphthene-based mineral oil, a chlorinated paraffin or a liquid organic ester or Ether connection or the like. Anyway is the base to be selected so that the protective agent ultimately contains pronounced water-repellent components.

Flüssige Korrosionsschutzmittel 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-Basie 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 Einlagenelemente führte zu überraschend günstigen Ergebnissen, die sich in einer wesentlich verminderten Korrosionsanfälligkeit und einer gleichzeitig verbessert in 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 anti-corrosive agents for the surface treatment of freely stretched or traction ropes used in any other exposed arrangement are known per se. In the context of the problem at hand, came the use of such is usually based on oil, wax or petroleum jelly Any commercially available protective equipment that has been built up cannot be considered from the outset because this would seriously impair the adhesive bond were to be expected. Contrary to all experience in practice, the novel approach to pretreatment adopted according to the invention of the insert elements led to surprisingly favorable results, which resulted in a significantly reduced susceptibility to corrosion and one at the same time showed improved dynamic efficiency of the insoles and also under the tough alternating bending stresses E.g. a steel cord conveyor belt withstood a long-term test. The reason for this is probably a combination of several Individual effects that are important in themselves: On the one hand, it is possible for the elastomeric material mixture in its To penetrate deep between the individual wires prior to crosslinking. On the other hand, the finest remaining cavities are also included filled with a water-repellent agent that simultaneously acts as a lubricant to prevent the direct metallic sliding friction within the ropes prevents, and ultimately forms regardless of their surface shape The coating surrounding the wire ropes provides reliable protection against cracks and other damage in the Embedding material penetrating moisture. An additional advantage is that given before the insert elements are processed To evaluate protective effect.

Die Erfindung stellt auf gute Verträglichkeit des Korrosionsschutzmittels mit der Zusammensetzung der elastomeren Werkstoffmischungen ab, so daß dieses an den beabsichtigten Bindungsstellen von den Mischungen euch aufgenommen wird. Ihre Anwendbarkeit setzt daher keine Änderungen in dem üblichen Mischungsaufbau voraus.The invention focuses on good compatibility of the corrosion protection agent with the composition of the elastomeric material mixtures, so that this is absorbed by the mixtures at the intended binding sites. Their applicability therefore does not make any changes in the usual mix structure.

Die Erfindung ist anhand der schematischen Darstellung eines Ausführungsbeispiels in der Zeichnung verdeutlicht. Die einzige Figur der Zeichnung The invention is illustrated by means of the schematic representation of an exemplary embodiment in the drawing. The only figure in the drawing

Der gezeichnete Fördergurt ist in an sich bekannter Weise aus einer oberen und einer unteren Deckplatte 1 und 2 und einer zwischen diese eingesetzten, die mit gegenseitigen Abständen parallel zueinander in Längsrichtung durchlaufenden Drahtseile h als Festigkeitsträger enthaltenden Kernschicht 3 aufgebaut. Während die beiden Deckplatten 1, 2 mit Bücksicht auf die mechanischen Beanspruchungen aus einer abriebfesten, zähharten Kautschukmischung bestehen, ist die innere Kernschicht 3 vorwiegend auf gute stoffschlüssige Bindung einerseits zu den Deckplatten und andererseits zu den eingebetteten Drahtseilen k ausgelegt.The conveyor belt shown is constructed in a manner known per se from an upper and a lower cover plate 1 and 2 and a core layer 3 which is inserted between these and contains the wire ropes h as reinforcement supports, which run parallel to one another in the longitudinal direction. While the two cover plates 1, 2 consist of an abrasion-resistant, tough rubber mixture, taking into account the mechanical loads, the inner core layer 3 is mainly designed for a good material bond on the one hand to the cover plates and on the other hand to the embedded wire ropes k .

Die Drahtseile k sind mit einem naphtenbasisches öl enthaltenden Korro-είonsschutzmittel überzogen, was in der Zeichnung mit dem Bezugszeichen 5 angedeutet ist.The wire ropes k are coated with a corrosion protection agent containing naphthenic oil, which is indicated in the drawing with the reference number 5.
