Abstract

The lubricants contain as main components, 5-30C satd. or unsatd. fatty acids or their esters, or mixts. of these. The main constituent is pref. castor oil, with addn. of thickening, bonding or corrosion-resistant additives, or anti-oxidants. They may also contain one or more alcohols, esp. diacetone alcohol, to reduce the viscosity and assist penetration to the core. The lubricants give much reduced swelling and softening of rubber covers on rollers in contact with cables, compared with the usual mineral oil-based lubricants.

Description

  

  
 



   Die vorliegende Erfindung bezieht sich auf ein Schmiermittel für Stahlseile.



   Schmiermittel für Stahlseile werden in erster Linie eingesetzt, um die einzelnen Seillitzen durch einen Schmierfilm voneinander zu trennen, d. h. zu schmieren und dadurch den Verschleiss zu vermindern, sowie das Stahlseil als Ganzes gegen Korrosion zu schützen.



   Die heute handelsüblichen Seilschmiermittel bestehen zur Hauptsache aus Mineralöl verschiedener Viskositäten, die in der Regel mit organischen undloder anorganischen Verdikkungsmitteln aufgesteift sind und meist weitere Zusätze, wie Haft- und Korrosionsschutzmittel sowie Antioxidantien enthalten. Zur Kennzeichnung sind die Schmiermittel gegebenenfalls durch Farbstoffzusätze eingefärbt. Die in allen Ländern unterschiedlichen Spezifikationen werden in der Regel von den auf dem Markt erhältlichen Seilschmiermitteln erfüllt.



   In Abhängigkeit von der Art der Anwendung sind die bekannten Seilschmiermittel in verschiedenen Formen erhältlich.



   Zur Anwendung während der Herstellung von Stahlseilen wird die Seele des Stahlseils vor der Verseilung mit den Stahllitzen mittels sogenanntem Seileinlagefett präpariert, wobei das Fett über seinen Tropfpunkt, beispielsweise auf etwa 60   1000C,    erwärmt und die Seele durch das verflüssigte Fett gezogen wird. Hierbei dringt das flüssige Schmiermittel in die Seele ein und durchtränkt diese, wobei die Aufnahme an Fett vorzugsweise 10-15 Gew.-%, bezogen auf das Gewicht der Seele, beträgt. Nach Fertigstellung des Stahlseils gewährleistet dieser Gehalt an Schmiermittel in der Seele die Schmierung des Stahlseils im belasteten Zustand von innen heraus während einer längeren Zeitdauer.

  Da sich das Schmiermittel jedoch zweckgebunden nach und nach von der Seele aus durch die Stahllitzen-Umwicklung nach aussen zur Oberfläche des Stahlseils hin ausbreitet, tritt ein Verbrauch an Schmiermittel ein, das zu gegebener Zeit durch Zuführung von Schmiermittel von aussen her ersetzt werden muss.



   Für diese Nachschmierung von im Gebrauch stehenden Stahlseilen werden die Schmiermittel auf verschiedene Art von aussen her auf die Stahlseile aufgetragen, wobei angestrebt wird, dass die Schmiermittel bis zur Seele des Seils durchdringen und dadurch die Schmierung im ganzen Seil gewährleisten.



  Zur Erleichterung des Auftrages und um das Eindringen des Schmiermittels in das Seilinnere zu unterstützen, werden die Schmiermittel im allgemeinen mit organischen Lösungsmitteln, bevorzugt mit chlorierten Kohlenwasserstoffen, vermischt, um deren Viskosität herabzusetzen und die Netzwirkung zu erhöhen. In geschlossenen Räumen, Fahrstuhlschächten und dergleichen werden diese Lösungsmittelzusätze normalerweise weggelassen und dafür als Schmiermittel bevorzugt Öle von niedrigerer Viskosität eingesetzt, um Geruchsbelästigung durch Verdampfung der Lösungsmittel zu vermeiden.



   Ein wichtiger, in allen Spezifikationen für Seilschmiermittel vorkommender Prüftest ist deren Verhalten gegen Seilrollenfütterungen, die normalerweise zur Hauptsache aus Gummi bestehen. Die hierfür gebräuchlichste Prüfmethode ist die
Bestimmung der Volumenveränderung von  Semperit -Rondellen als Prüfkörper in Form zylindrischer Scheiben von 45 mm Durchmesser und 6 mm Dicke. Die Prüfung wird durchgeführt, indem solche Prüfkörper während je 27 Tagen in das zu prüfende Schmiermittel von 200C bzw. 500C eingelegt und danach deren Volumenveränderung und Veränderung der
Shorehärte bestimmt werden.



   Beim heutigen Stand der Technik ist die obere Toleranzgrenze für die Volumenvergrösserung aufgrund der Gummiquellung für die Prüfung bei 200C auf 10 Vol.   So    und bei   500C    auf 25   Vol.%    festgesetzt, und es wird ein Rückgang der Shorehärte der Prüfkörper von bis zu 12 Einheiten toleriert.



   Die handelsüblichen Seilschmiermittel ergeben bei der Prüfung bei 500C Minimalwerte der Volumenvergrösserung im Bereich von 12 Vol.% und bewegen sich bis zur zulässigen oberen Grenze von 25 Vol.%.



   Die vorstehend genannten Lösungsmittel, die handelsüblichen Seilschmiermitteln zur Herabsetzung der Viskosität und zur Erhöhung der Netzwirkung zugesetzt werden und auch als Reinigungsmittel für Stahlseile zum Einsatz gelangen, ergeben nach der vorstehend beschriebenen Prüfmethode Quellwerte von über 100 Vol.%.



   Es ist Gegenstand der vorliegenden Erfindung, ein Seilschmiermittel zu schaffen, das unter Erhaltung einer guten Schmierwirkung eine wesentlich verminderte Volumenzunahme und wesentlich verminderten Rückgang der Shorehärte ergibt.



   Diese Aufgabe wird durch das erfindungsgemässe Stahlseilschmiermittel erfüllt, as als hauptsächliche Komponente eine gesättigte oder ungesättigte Fettsäure mit 5-30 C-Atomen oder einen Ester einer solchen Säure oder ein Gemisch davon enthält.



   In einer bevorzugten Ausführungsform besteht das erfindungsgemässe Seilschmiermittel aus einem Gemisch von gesättigten und ungesättigten Fettsäuren und zur Hauptsache aus Rizinusöl. Laut Literaturangaben setzt sich Rizinusöl aus ungefähr   75-95%    Rizinolsäure,   0-5%    Stearinsäure,   1-10Gc    Ölsäure und 1-7% Linolsäure zusammen.



   Das erfindungsgemässe Seilschmiermittel kann ausserdem die üblichen Zusätze, wie Verdickungs-, Haft- und Korrosionsschutzmittel sowie Antioxidantien enthalten.



   Das beschriebene Seilschmiermittel ergab bei der vorstehend beschriebenen Prüfung bei   200C    eine Volumenzunahme von ungefähr 0,1 Vol.% und bei 50oC von ungefähr 1   Vol.%    und der Rückgang der Shorehärte betrug im Maximum 2 Einheiten.



   In einer besonderen Ausführungsform enthält das beschriebene Seilschmiermittel als Lösungsmittel zur Herabsetzung der Viskosität und Erhöhung der Netzwirkung einen oder mehrere Alkohole. Vorzugsweise wird hierfür Diacetonalkohol eingesetzt, der bei der vorstehend beschriebenen Prüfung bei   500C    eine Volumenzunahme von ungefähr 2 Vol.% ergab. 



  
 



   The present invention relates to a lubricant for steel cords.



   Lubricants for steel ropes are primarily used to separate the individual rope strands from one another by means of a lubricating film. H. to lubricate and thereby reduce wear, and to protect the steel cable as a whole against corrosion.



   The rope lubricants commercially available today mainly consist of mineral oil of various viscosities, which are usually stiffened with organic and / or inorganic thickeners and usually contain other additives such as adhesives, anti-corrosion agents and antioxidants. For identification purposes, the lubricants are colored with additives if necessary. The different specifications in all countries are usually met by the rope lubricants available on the market.



   The known rope lubricants are available in various forms, depending on the type of application.



   For use during the manufacture of steel ropes, the core of the steel cable is prepared with so-called rope insert grease prior to stranding with the steel strands, the grease being heated above its drop point, for example to around 60 1000C, and the core being pulled through the liquefied fat. Here, the liquid lubricant penetrates the core and saturates it, the fat absorption preferably being 10-15% by weight, based on the weight of the core. After completion of the steel cable, this content of lubricant in the core ensures the lubrication of the steel cable in the loaded state from the inside out for a longer period of time.

  However, since the lubricant gradually spreads from the core through the steel strand wrapping to the surface of the steel cable, the lubricant is consumed and has to be replaced in due course by adding lubricant from the outside.



   For this relubrication of steel ropes in use, the lubricants are applied to the steel ropes in various ways from the outside, the aim being that the lubricants penetrate to the core of the rope and thereby ensure lubrication throughout the rope.



  To make the application easier and to help the lubricant to penetrate the interior of the rope, the lubricants are generally mixed with organic solvents, preferably with chlorinated hydrocarbons, in order to reduce their viscosity and increase the wetting effect. In closed rooms, elevator shafts and the like, these solvent additives are normally left out and oils of lower viscosity are preferably used as lubricants in order to avoid odor nuisance due to evaporation of the solvents.



   An important test test that occurs in all specifications for rope lubricants is their behavior against rope pulley feeds, which normally consist mainly of rubber. The most common test method for this is
Determination of the change in volume of Semperit® washers as test specimens in the form of cylindrical disks 45 mm in diameter and 6 mm thick. The test is carried out by placing such test specimens in the lubricant to be tested at 200C or 500C for 27 days and then changing their volume and changing the
Shore hardness can be determined.



   With the current state of the art, the upper tolerance limit for the increase in volume due to rubber swelling for the test at 200C is set at 10 vol.% And at 500C at 25 vol.%, And a decrease in the Shore hardness of the test specimens of up to 12 units is tolerated .



   When tested at 500C, the commercially available rope lubricants result in minimum values for the volume increase in the range of 12 vol.% And move up to the permissible upper limit of 25 vol.%.



   The solvents mentioned above, which are added to commercially available rope lubricants to reduce the viscosity and increase the wetting effect and are also used as cleaning agents for steel ropes, result in swelling values of over 100% by volume according to the test method described above.



   The object of the present invention is to create a rope lubricant which, while maintaining a good lubricating effect, results in a significantly reduced increase in volume and a significantly reduced decrease in Shore hardness.



   This object is achieved by the steel rope lubricant according to the invention, which contains as the main component a saturated or unsaturated fatty acid with 5-30 C atoms or an ester of such an acid or a mixture thereof.



   In a preferred embodiment, the rope lubricant according to the invention consists of a mixture of saturated and unsaturated fatty acids and mainly of castor oil. According to the literature, castor oil is made up of approximately 75-95% ricinoleic acid, 0-5% stearic acid, 1-10% oleic acid and 1-7% linoleic acid.



   The rope lubricant according to the invention can also contain the usual additives, such as thickeners, adhesives and anti-corrosion agents, and also antioxidants.



   In the test described above, the rope lubricant described resulted in an increase in volume of approximately 0.1% by volume at 200 ° C. and of approximately 1% by volume at 50 ° C. and the decrease in Shore hardness amounted to a maximum of 2 units.



   In a particular embodiment, the rope lubricant described contains one or more alcohols as a solvent to reduce the viscosity and increase the wetting effect. Diacetone alcohol is preferably used for this purpose, which in the test described above at 50 ° C. resulted in an increase in volume of approximately 2% by volume.
