Description

Die Erfindung bezieht sich auf eine Flüssigkeit, die für Schmierzwecke und zur mechanischen Kraftübertragung verwendet werden kann, beispielsweise für Bremseinrichtungen sowie Aufhänge- bzw. Lager- und Lenkvorrichtungen bei mit Motoren ausgerüsteten Wagen und für •Getriebe,The invention relates to a fluid that is used for lubrication purposes and for mechanical power transmission can be used, for example, for braking devices and suspension or storage and steering devices for wagons equipped with engines and for • gearboxes,

Flüssigkeiten dieser Art müssen über einen weiten Temperatur- und Druckbereich gute Schmiereigenschaften aufweisen. Insbesondere müssen sie auch eine geeignete Viskosität haben, um einen zu hohen Kraft- ίο verbrauch oder ein übermäßiges Lecken der betreffenden Vorrichtungen zu vermeiden. In vielen Fällen sind Viskositäten von etwa 12 bis 13 cSt bei 500C erforderlich. Hydraulische Flüssigkeiten müssen auch einen hohen Viskositätsindex aufweisen, d. h. eine geringe Verschiebung der Viskosität bei Temperaturänderungen zeigen, und sie dürfen sich selbst bei sehr niederen Wintertemperaturen nicht verfestigen. Sie sollen ferner während des Gebrauchs nicht verdampfen und auch einen hohen Flammpunkt und eine gewisse Verträglichkeit gegenüber Wasser aufweisen. Auch dürfen diese Flüssigkeiten keine auf Metalle korrodierend wirkenden Substanzen enthalten, und sie sollen Kautschuk nicht angreifen.Liquids of this type must have good lubricating properties over a wide temperature and pressure range. In particular, they must also have a suitable viscosity in order to avoid excessive power consumption or excessive leakage of the devices in question. In many cases, viscosities of about 12 to 13 cSt at 50 ° C. are required. Hydraulic fluids must also have a high viscosity index, that is, show a small shift in viscosity with changes in temperature, and they must not solidify even at very low winter temperatures. Furthermore, they should not evaporate during use and should also have a high flash point and a certain compatibility with water. These liquids must not contain any substances that corrode metals, and they should not attack rubber.

Bekannte Schmiermittel und Kraftübertragungsflüssigkeiten bestehen beispielsweise aus 50 Volumprozent Ricinusöl und 50 Volumprozent Diacetonalkohol oder aus Gemischen von Ricinolsäureestern bzw. Polypropylenglykol mit anderen Äthern oder Alkoholen, wobei die Mischungsverhältnisse variieren können. Es ist jedoch sehr schwierig, die Zusammensetzung der Schmiermittel so auszuwählen, daß alle obenerwähnten Anforderungen hinsichtlich der Viskosität, des Viskositätsindex, der geringen Verdampfbarkeit, des ausreichend hohen Flammpunktes und der Verträglichkeit mit Wasser praktisch erfüllt sind.Known lubricants and power transmission fluids, for example, consist of 50 percent by volume Castor oil and 50 percent by volume of diacetone alcohol or from mixtures of ricinoleic acid esters or polypropylene glycol with other ethers or alcohols, whereby the mixing ratios can vary. However, it is very difficult to select the composition of the lubricants so that all of the above requirements with regard to the viscosity, the viscosity index, the low vaporizability, the sufficiently high flash point and compatibility with water are practically fulfilled.

Es wurde nun gefunden, daß dieses Problem gelöst werden kann, wenn man ein Schmiermittel bzw. eine Kraftübertragungsflüssigkeit auf der Basis von Alkyläthern und gegebenenfalls Polyoxyalkylenverbindungen so zusammensetzt, daß die Flüssigkeit 35 bis 70 Gewichtsprozent eines oder mehrerer Alkyläther mehrwertiger Alkohole sowie 30 bis 65 Gewichtsprozent eines Gemisches enthält, welches aus einer flüssigen Polyoxyalkylenverbindung und/oder einem neutralen Ester einer aliphatischen Dicarbonsäure sowie einem modifizierten Ricinusöl mit einer Viskosität zwischen 20 und 600 Poise bei 200C und einer Säurezahl unter 20, vorzugsweise unter 5, besteht.It has now been found that this problem can be solved if one composes a lubricant or a power transmission fluid based on alkyl ethers and optionally polyoxyalkylene compounds so that the fluid contains 35 to 70 percent by weight of one or more alkyl ethers of polyhydric alcohols and 30 to 65 percent by weight of one Contains mixture which consists of a liquid polyoxyalkylene compound and / or a neutral ester of an aliphatic dicarboxylic acid and a modified castor oil with a viscosity between 20 and 600 poise at 20 ° C. and an acid number below 20, preferably below 5.

Das modifizierte Ricinusöl wird hergestellt, indem man Ricinusöl auf eine verhältnismäßig niedere Temperatur erhitzt, bis es die angegebene Viskosität und Säurezahl erreicht, wobei wahrscheinlich eine Polymerisation stattfindet.

gegenüber Wasser zu erhalten, d. h. um zu erreichen, daß sie verhältnismäßig große Mengen an Wasser aufnehmen kann, ohne daß Phasentrennung eintritt, kann das Ricinusöl während des Erhitzens auch noch oxydiert werden, z. B. indem man Luft oder irgendein anderes, Sauerstoff enthaltendes Gas durch das Öl hindurchperlen läßt. Es scheint, daß dann Sauerstoffbrücken zwischen den Doppelbindungen der Ricinolsäure gebildet werden und dadurch Polymerisation eintritt.to preserve water, d. H. to make them absorb relatively large amounts of water can without phase separation occurring, the castor oil can also be oxidized during heating be e.g. By bubbling air or some other oxygen-containing gas through the oil leaves. It appears that oxygen bridges are then formed between the double bonds of ricinoleic acid and thereby polymerization occurs.

Im Rahmen der Erfindung geeignete flüssige Polyoxyalkylenverbindungen sind die Polyoxyalkylenglykole sowie ihre Mono- und Diäther oder -ester, welche die allgemeine Formel R, —-O — [R2 O]n — R3 aufweisen.Liquid polyoxyalkylene compounds suitable for the purposes of the invention are the polyoxyalkylene glycols and their mono- and diethers or esters, which have the general formula R, —- O - [R 2 O] n - R 3 .

In dieser Formel bedeuten R1 und R3 jeweils ein Wasserstoffatom oder einen Kohlenwasserstoffrest (vorzugsweise aliphatisch) oder eine Acylgruppe. R2 ist ein Alkylenrest, vorzugsweise einen Alkylenrest, mit 2 bis 8 Kohlenstoffatomen und η eine ganze Zahl.In this formula, R 1 and R 3 each represent a hydrogen atom or a hydrocarbon radical (preferably aliphatic) or an acyl group. R 2 is an alkylene radical, preferably an alkylene radical, with 2 to 8 carbon atoms and η is an integer.

Die Polyoxyalkylenkette —[R2 O]n — kann auch Alkylenreste mit einer verschiedenen Zahl von Kohlenstoffatomen enthalten, beispielsweise Oxyäthylen- und Qxypropylenreste.The polyoxyalkylene chain - [R 2 O] n - can also contain alkylene radicals with a different number of carbon atoms, for example oxyethylene and oxypropylene radicals.

Die Polyoxypropylenglykole sind besonders geeignet, insbesondere solche mit einem Molgewicht von etwa 2000.The polyoxypropylene glycols are particularly suitable, especially those with a molecular weight of about 2000.

Um ein Schmiermittel mit guter Wasserverträglichkeit zu erhalten, ist aber die Verwendung einer Polyoxyalkylenflüssigkeit derjenigen eines neutralen Esters einer aliphatischen Dicarbonsäure vorzuziehen.In order to obtain a lubricant with good water compatibility, however, it is necessary to use a polyoxyalkylene liquid preferable to that of a neutral ester of an aliphatic dicarboxylic acid.

Von den als weitere Komponente in den erfindungsgemäßen Schmiermitteln verwendeten Äthern mehrwertiger Alkohole werden die Alkyläther aliphatischer mehrwertiger Alkohole, insbesondere die Monoalkyläther, bevorzugt. Die Monoalkyläther von Glykol und Diglykol sind ganz besonders geeignet. Beispiele geeigneter Äther sind der Monoäthyläther, der Monohexylbutyläther von Äthylenglykol, der Monoisopropyläther von Diäthylenglykol, der Monoäthyläther von Dipropylenglykol und der Monoäthyläther von Äthylenpropylenglykol.Of the ethers used as a further component in the lubricants according to the invention, polyvalent Alcohols are the alkyl ethers of aliphatic polyhydric alcohols, especially the monoalkyl ethers, preferred. The monoalkyl ethers of glycol and diglycol are particularly suitable. Examples of suitable ethers are the monoethyl ether, the monohexyl butyl ether of ethylene glycol, the monoisopropyl ether of diethylene glycol, the monoethyl ether of dipropylene glycol and the monoethyl ether of ethylene propylene glycol.
