Abstract

This saw chain lubricant is composed essentially of water and a water-soluble antifreeze agent, as main constituents, and of corrosion inhibitors, wear inhibitors and adhesion promoters in a quantity which is effective in each case, the adhesion promoter being a water-soluble polyethylene glycol and/or a water-soluble acrylamide copolymer which contains sulfonic acid groups, the molecular weight of each being at least 500,000. In combination with this adhesion promoter, which is present in an amount of 0.05 to 1% by weight, the lubricant contains 5 to 50% by weight of a water-soluble polyethylene oxide/polypropylene oxide adduct having a viscosity of at least 300 mPa.s at 50 DEG C., as a special lubricant, percentages by weight relating in each case to the weight of the agent.

Description

Die Erfindung betrifft ein Schmiermittel für Sägeketten, das im wesentlichen aus Wasser und einem wasserlöslichen Frostschutzmittel als Hauptbestandteile, Korrosionsinhibitoren, Verschleißinhibitoren und Haftvermittlern besteht und insbesondere einen lang andauernden Betrieb der Sägeketten-Maschine gewährleistet.The invention relates to a lubricant for saw chains, which consists essentially of water and a water-soluble antifreeze as the main components, corrosion inhibitors, wear inhibitors and adhesion promoters and in particular ensures long-term operation of the saw chain machine.

Zum Schmieren von Kettensägen, wie sie beispielsweise in der Forstwirtschaft zum Fällen von Bäumen verwendet werden, sind Schmiermittel auf der Basis von Mineralöl oder synthetische Produkte in Gebrauch. Auch zum Schmieren von stationär betriebenen Sägen wie Gattersägen, werden derartige Schmiermittel eingesetzt.Lubricants based on mineral oil or synthetic products are used to lubricate chainsaws, such as those used in forestry to fell trees. Such lubricants are also used to lubricate stationary saws such as frame saws.

Die auf Mineralöl basierenden Schmiermittel befriedigen zwar bezüglich Verschleißschutz und Korrosionsverhalten, jedoch werden dagegen zunehmend ökologische Bedenken vorgebracht, weil sie aufgrund des Mineralöls nicht biologisch abbaubar sind.The lubricants based on mineral oil are satisfactory in terms of wear protection and corrosion behavior, but ecological concerns are increasingly being raised because they are not biodegradable due to the mineral oil.

Die bekannten synthetischen Sägeketten-Schmiermittel bestehen im wesentlichen aus Wasser und aus einem wasserlöslichen Frostschutzmittel, vorzugsweise Glykolen, Glykolethern und/oder dreiwertigen aliphatischen Alkoholen wie Glycerin, gegebenenfalls gemeinsam mit einwertigen niedrigen aliphatischen Alkoholen wie Isopropanol, als Hauptbestandteile. Neben diesen Hauptbestandteilen enthalten sie in einer jeweils wirksamen Menge Korrosionsinhibitoren, Verschleißinhibitoren und Haftvermittler.The known synthetic saw chain lubricants consist essentially of water and a water-soluble antifreeze, preferably glycols, glycol ethers and / or trihydric aliphatic alcohols such as glycerol, optionally together with monohydric lower aliphatic alcohols such as isopropanol, as the main constituents. In addition to these main components, they each contain an effective amount of corrosion inhibitors, wear inhibitors and adhesion promoters.

Die Korrosionsschutz- und die Verschleißschutz-Additive sollen insbesondere die Kettenglieder, die Kettenführung und das Antriebsritzel vor Korrosion und Verschleiß schützen. Dazu werden gegebenenfalls auch sogenannte extreme pressure-additives (EP-additives) eingesetzt. Die Haftadditive sollen einerseits viskositätsregulierend wirken und andererseits das Abschleudern des Schmiermittels von der Sägekette während des Betriebs möglichst weitgehend verhindern. Eine wirksame Verhinderung hängt insbesondere damit zusammen, daß das eingesetzte Haftadditiv die Eigenschaft besitzt, das fertige Schmiermittel fadenziehend zu machen.The corrosion protection and wear protection additives are intended in particular to protect the chain links, the chain guide and the drive pinion from corrosion and wear. Extreme pressure additives (EP additives) may also be used for this purpose. On the one hand, the adhesive additives should have a viscosity-regulating effect and, on the other hand, should largely prevent the lubricant from being thrown off the saw chain during operation. An effective prevention is particularly related to the fact that the adhesive used has the property of making the finished lubricant thread-pulling.

Die in den bekannten Sägeketten-Schmiermitteln aus Wasser und Frostschutzmittel als Hauptbestandteile benutzten Haftvermittler vermögen zwar die Viskosität der Grundbestandteile zu erhöhen, sie fallen jedoch während des Betriebes der Sägeketten-Maschine infolge Verdampfung von Wasser aus, wodurch nicht nur ihre viskositätsregulierende, sondern auch ihre fadenziehende Wirkung weitgehend verlorengeht. Durch die während des Betriebes herrschenden Scherkräfte wird das Haftadditiv schließlich vollständig zerstört.The adhesion promoters used as main components in the known saw chain lubricants made of water and antifreeze may increase the viscosity of the basic components, but they fail during the operation of the saw chain machine due to evaporation of water, which means that not only its viscosity-regulating but also its thread-pulling Effect is largely lost. The adhesive additive is finally completely destroyed by the shear forces prevailing during operation.

Diese bekannten Sägeketten-Schmiermittel sind demnach insbesondere hinsichtlich Viskositätsverhalten und Haftwirkung nicht zufriedenstellend. Aufgrund dieser Nachteile ermöglichen sie auch keinen dauerhaften Betrieb.These known saw chain lubricants are therefore unsatisfactory, in particular with regard to viscosity behavior and adhesive effect. Because of these disadvantages, they do not enable permanent operation.

Aufgabe der Erfindung ist es daher, ein Schmiermittel für Sägeketten auf der Basis von Wasser und üblichen Frostschutzmitteln bereitzustellen, das die Nachteile der bekannten derartigen Mittel nicht aufweist. Das neue Sägeketten-Schmiermittel soll nicht nur hinsichtlich Korrosionsschutz und Verschleißschutz, sondern insbesondere auch hinsichtlich Schmierwirkung, Viskosität und Haftung ausgezeichnete Eigenschaften aufweisen. Es soll darüber hinaus auch dann noch voll wirksam sein, wenn während des Betriebes der Sägeketten-Maschine das Wasser teilweise oder ganz verdampft, und somit einen lang andauernden Betrieb gewährleisten.The object of the invention is therefore to provide a lubricant for saw chains based on water and conventional antifreeze agents, which does not have the disadvantages of the known agents of this type. The new saw chain lubricant should not only have excellent properties in terms of corrosion protection and wear protection, but also in particular with regard to lubrication, viscosity and adhesion. It should also still be full be effective if the water evaporates partially or completely during operation of the saw chain machine, thus ensuring long-term operation.

Diese Aufgabe wird erfindungsgemäß gelöst mit einem Schmiermittel für Sägeketten, bestehend im wesentlichen aus Wasser und einem wasserlöslichen Frostschutzmittel als Hauptbestandteile und aus Korrosionsinhibitoren, Verschleißinhibitoren und Haftvermittler in einer jeweils wirksamen Menge, dadurch gekennzeichnet, daß der Haftvermittler ein wasserlösliches Polyethylenglykol und/oder ein Sulfonsäuregruppen enthaltendes und wasserlösliches Acrylamidcopolymer mit einem Molekulargewicht von jeweils mindestens 500 000 ist, in einer Menge von 0,05 bis 1 Gew.-%, bezogen auf das Gewicht des Mittels, und daß es zusätzlich 5 bis 50 Gew.-%, bezogen auf das Gewicht des Mittels, wasserlösliches Polyethylenoxid-Polypropylenoxid-Addukt mit einer Viskosität von mindestens 300 mPa s bei 50 °C enthält.This object is achieved according to the invention with a lubricant for saw chains consisting essentially of water and a water-soluble antifreeze as the main constituents and of corrosion inhibitors, wear inhibitors and adhesion promoters in an effective amount in each case, characterized in that the adhesion promoter contains a water-soluble polyethylene glycol and / or a sulfonic acid group and water-soluble acrylamide copolymer having a molecular weight of at least 500,000 each, in an amount of 0.05 to 1% by weight based on the weight of the agent, and that it is additionally 5 to 50% by weight based on the weight of the agent, contains water-soluble polyethylene oxide-polypropylene oxide adduct with a viscosity of at least 300 mPa s at 50 ° C.

Das neue Sägeketten-Schmiermittel besitzt überraschenderweise besonders gute rheologische Eigenschaften, eine hohe Schmierwirkung und ein hervorragendes Haftvermögen. Es wirkt auch dann noch funktionsgerecht, wenn die Komponente Wasser während des Betriebes verdampft. Diese hervorragenden Eigenschaften dürften insbesondere auf die spezielle Kombination der erfindungsgemäß vorhandenen Haftvermittler und Polyethylenoxid-Polypropylenoxid-Addukte zurückzuführen sein. Diese beiden Komponenten ergänzen sich offensichtlich in einem unerwartet hohen Ausmaß hinsichtlich Viskosität, Schmierung, Haftung und rheologischem Verhalten des Mittels, auch wenn mehr oder weniger große Teile der Hauptkomponente Wasser nicht mehr vorliegen.The new saw chain lubricant surprisingly has particularly good rheological properties, a high lubricating effect and excellent adhesion. It still functions properly if the component evaporates water during operation. These outstanding properties should in particular be attributable to the special combination of the adhesion promoters and polyethylene oxide-polypropylene oxide adducts present according to the invention. These two components obviously complement each other to an unexpectedly high degree in terms of viscosity, lubrication, adhesion and rheological behavior of the agent, even if more or less large parts of the main component water are no longer present.

Die Menge an Wasser (Komponente A) im erfindungsgemäßen Mittel beträgt im allgemeinen 30 bis 60 Gew.-%, vorzugsweise 35 bis 50 Gew.-%, bezogen auf das Gewicht des Mittels (des gesamten Mittels).The amount of water (component A) in the composition according to the invention is generally 30 to 60% by weight, preferably 35 to 50% by weight, based on the weight of the composition (of the entire composition).

This is expediently carried out in a container equipped with a stirrer, the components advantageously being introduced in succession at room temperature and mixed with stirring.

Die Erfindung wird nun an Beispielen noch näher erläutert.The invention will now be explained in more detail using examples.

Beispiel 1example 1

Die in der nachstehenden Tabelle I in Kolonne 1 angegebenen Mengen der einzelnen Komponenten eines erfindungsgemäßen Schmiermittels werden bei Raumtemperatur vermischt. Dabei wird in das vorgelegte Diethylenglykol zunächst das Polyethylenglykol, Molekulargewicht 5 000 000, und anschließend das Wasser eingerührt, worauf die vorliegende Suspension bis zum vollständigen Quellen stehengelassen wird. Nun werden die übrigen Komponenten wiederum unter Rühren zugesetzt.The amounts of the individual components of a lubricant according to the invention given in column 1 in Table I below are mixed at room temperature. The polyethylene glycol, molecular weight 5,000,000, and then the water are first stirred into the diethylene glycol provided, whereupon the present suspension is left to swell completely.

In diesen Beispielen wird analog Beispiel 1 vorgegangen, wobei die in der Tabelle I in den Kolonnen 2 bis 9 angegebenen erfindungsgemäßen Schmiermittel erhalten werden. Sie weisen die in den Kolonnen 2 bis 9 der Tabelle II angeführten Eigenschaftwerte auf.In these examples, the procedure is analogous to Example 1, the lubricants according to the invention given in columns I to columns 2 to 9 being obtained.

VergleichsbeispielComparative example

In der Tabelle II sind die Eigenschaftswerte eines dem Stand der Technik entsprechenden synthetischen Schmiermittels für Sägeketten angegeben.Table II shows the property values of a state-of-the-art synthetic lubricant for saw chains.

Wie aus der Tabelle II hervorgeht, besitzt das erfindungsgemäße Schmiermittel, verglichen mit dem bekannten, eine viel vorteilhaftere Viskosität. Es zeigt auch noch bei hohen Schergeschwindigkeiten ein günstiges Viskositätsverhalten, was für den bestimmungsgemäßen Einsatz besonders wichtig ist. Der erfindungsgemäß eingesetzte Haftvermittler bleibt auch nach dem Abdampfen des Wassers voll wirksam, während der im Vergleichsbeispiel anwesende seine fadenziehende Wirkung relativ schnell verliert. Das erfindungsgemäße Schmiermittel weist im Gegensatz zum bekannten auch eine hervorragende Verschleißschutzwirkung auf.

 As can be seen from Table II, the lubricant according to the invention has a much more advantageous viscosity compared to the known one. It shows a favorable viscosity behavior even at high shear rates, which is particularly important for the intended use. The adhesion promoter used according to the invention remains fully effective even after the water has evaporated, while that present in the comparative example loses its stringy effect relatively quickly. In contrast to the known lubricant, the lubricant according to the invention also has an excellent wear protection effect.
