Description
Als Schmiermittel und zur Kraftübertragung geeignete Flüssigkeit Die vorliegende Erfindung bezieht sich auf eine Flüssigkeit, die für Schmierzwecke und zur mecha nischen Kraftübertragung verwendet werden kann. Derartige Flüssigkeiten werden insbesondere für Bremseinrichtungen sowie Aufhänge- bzw. Lager und Lenkvorrichtungen bei mit Motoren ausgerüste ten Wagen und für Getriebe verwendet.
Damit Flüssigkeiten dieser Art unter den Anwen dungsbedingungen befriedigend arbeiten, müssen sie über einen weiten Temperatur- und Druckbereich gute Schmiereigenschaften aufweisen. Sie müssen auch eine geeignete Viskosität haben. Eine hoch viskose Flüssigkeit vermeidet zwar übermässiges Lecken oder Gleiten in hydraulischen Pumpen, er zeugt aber einen hohen Widerstand gegenüber der Bewegung und verursacht so hohen Kraftverbrauch. Anderseits fliessen zwar Flüssigkeiten von sehr gerin ger Viskosität rasch; sie fördern aber ein übermässiges Lecken und ergeben schlechte Wirkung. In vielen Fällen sind Viskositäten von etwa 12 bis 13 Centi- stokes bei 50 erforderlich.
Hydraulische Flüssig keiten müssen über einen sehr weiten Temperatur bereich verwendbar sein. Sie müssen daher einen hohen Viskositätsindex aufweisen, das heisst eine ge ringe Verschiebung der Viskosität bei Temperatur änderungen zeigen. Sie dürfen nicht ausfrieren oder selbst bei sehr niederen Wintertemperaturen sich nicht verfestigen. Ihr Siedepunkt muss ausreichend hoch sein, so dass sie während des Gebrauchs nicht ver dampfen. Es ist auch ein hoher Flammpunkt und eine gewisse Toleranz gegenüber Wasser erforderlich. Chemisch soll die Flüssigkeit praktisch inert sein gegenüber den Stoffen, aus welchen die verschie denen Teile eines hydraulischen Systems hergestellt sind.
Zum Beispiel darf die Flüssigkeit keine auf Metalle korrodierend wirkenden Substanzen enthal ten, und sie darf auch Kautschuk nicht angreifen. Eine bekannte Art von Flüssigkeit dieses Typs besteht aus einem schmierend wirkenden Bestandteil und einem verdünnend wirkenden Bestandteil.
Ein spezielles Beispiel für eine Flüssigkeit dieser Art ent hält etwa 50 Vol:o/o Rizinusöl und etwa 50 Vol.o/o Diacetonalkohol. In anderen Flüssigkeiten dieser Art werden als schmierendes Element andere Verbindun gen verwendet, wie die Ester der Rizinolsäure oder Polypropylenglykol, oder andere Alkohole oder Äther im Verdünnungsmittel, oder das Schmiermittel und die verdünnenden Elemente werden in anderen Ver hältnissen als 50: 50 gemischt.
Es ist jedoch sehr schwer, eine optimale Kombi nation von Eigenschaften zu erzielen, und bisher ist es nicht möglich gewesen, eine Flüssigkeit herzu stellen, die gleichzeitig in jeder Hinsicht den sehr strengen Anforderungen entspricht. Es ist ein Ziel der vorliegenden Erfindung, dieses Problem in- tech nisch befriedigender Weise zu lösen.
Die Flüssigkeit gemäss vorliegender Erfindung enthält ebenfalls schmierende und verdünnende Kom ponenten. Als Schmiermittel wirkende Bestandteile: Eine wesentliche Komponente wird erhalten, indem man Rizinusöl so lang erhitzt, bis es eine Viskosität zwischen 20 und 600 Poise bei 20 erreicht hat. Das Rizinusöl wird dabei auf eine verhältnis mässig niedere Temperatur erhitzt, so dass es eine Säurezahl unter 20 und vorzugsweise unter 5 erhält. Das Rizinusöl wird während des Erhitzens wahr scheinlich polymerisiert. Dieses Produkt wird nach stehend als modifiziertes Rizinusöl bezeichnet.
Um eine Flüssigkeit mit hoher Beständigkeit gegenüber Wasser zu erhalten, das heisst, um zu errei chen, dass die Flüssigkeit verhältnismässig grosse Men gen Wasser aufnehmen kann, ohne dass Phasentren nung eintritt, kann das Rizinusöl während des Er- hitzens oxydiert werden, z. B. indem man Luft oder irgendein anderes, Sauerstoff enthaltendes Gas durch das Öl hindurchperlen lässt. Es scheint, dass Sauer stoffbrücken zwischen den Doppelbindungen der Rizinolsäure gebildet werden und dadurch Polyme- risation eintritt.
Als weitere schmierend wirkende Komponente enthält die erfindungsgemässe Flüssigkeit ein flüssiges Polyoxyalkylen, vorzugsweise der Formel Rl7 O-[R20]ri R3. In dieser Formel bedeuten R1 und R3 jeweils ein Wasserstoffatom oder einen Kohlenwasser stoffrest (vorzugsweise aliphatisch) oder eine Acyl- gruppe. R2 bedeutet einen Alkylenrest und n eine ganze Zahl.
In der Polyoxyalkylenkette -[R20]ri kann der R2 Rest jeden Alkylenrest bedeuten, vor zugsweise einen Alkylenrest mit 2 bis 8 Kohlenstoff atomen.
Die Polyoxyalkylenkette -[R20]ri kann Alkylen- reste enthalten, die eine verschiedene Zahl von Koh- lenstoffatomen aufweisen. Beispielsweise kann diese Kette Oxyäthylen- und Oxypropylenreste enthalten.
Wenn die Polyoxyalkylenkette verschiedene Alkylen- reste enthält, können diese willkürlich über das Mole kül verteilt oder in regelmässig sich wiederholenden Einheiten oder Blöcken angeordnet sein, von welchen jeder aus einem oder mehreren ähnlichen Oxyalkylen- resten besteht.
Die Polyoxypropylenglykole sind für die Verwen dung in Flüssigkeiten gemäss der vorliegenden Erfin dung besonders geeignet.
Bevorzugte Polyoxyalkylene haben Molgewichte zwischen 800 und 4000 oder besonders zweckmässig zwischen 1000 und 3000. Polyoxypropylenglykole mit einem Molgewicht von etwa 2000 sind ganz ausserordentlich wirksam.
Anstatt der Polyoxyalkylene oder in Verbindung mit diesen können neutrale Ester aliphatischer Di- carbonsäuren verwendet werden, am besten solche der Formel WOOC - R - COOR", in welcher R einen zweiwertigen, gesättigten aliphatischen Kohlenwasser stoffrest und R' und R" Alkyl-, Aralkyl- oder Cyclo- alkylreste bedeuten, die mehr als zwei Kohlenstoff atome enthalten.
Die Ester sind vorzugsweise von gesättigten ali- phatischen Dicarbonsäuren abgeleitet, z. B. von Malon-, Äthylmalon-, Bernstein-, Methyl-bernstein-, 1,1- oder 1,2-Diäthyl-bernstein-, Glutar-, 1- oder 2 Methyl-glutar-, 1,3-Diäthyl-glutar-, Adipin-l- oder 2-Methyladipin-, Pimelin-, 1,2,5-Trimethyl-pimelin-, Suberin-, Azelain-,
Sebacin-, Nonan-, 1,9-dicarbon- und Decan-1,10-dicarbonsäure, sowie vorzugsweise von Propanolen, Butanolen, Hexanolen, Octanolen und Nonanolen, oder Aralkanolen, z. B. Benzyl- und Phenyläthylalkohol, oder Cycloalkanole, z.
B. Cyclo- pentanol, Cyclohexanol und Methylcyclohexanol. Bei spiele geeigneter flüssiger Ester sind Adipinsäure-di-(2-methyl-heptyl)-ester, Adipinsäure-di-(3,5,5-trimethyl-hexyl)-ester oder Sebacinsäure-di-(3,5,5-trimethyl-hexyl)-ester, Adipinsäure-di-(3-äthyl-hexyl)-ester oder Sebacinsäure-di-(3-äthyl-hexyl)-ester, Pünelinsäure-di-hexylester, Sebacinsäure-di-(2-äthyl-hexyl)-ester, Sebacinsäure-di-sec-butylester,
Malonsäure-di-sec.-butylester, Azelainsäure-di-(1-äthylpropyl)-ester und Malonsäure-dibutyläthylester. Um eine Flüssigkeit mit hoher Wasserbeständig keit zu erhalten, ist die Anwendung einer Polyoxy- alkylenflüssigkeit der Verwendung eines neutralen Esters einer aliphatischen Dicarbonsäure vorzuziehen.
Verdünnende Komponenten: Ihr Anteil beträgt 35 bis 70 Gew.O/o, vorzugs- weise 40 bis 60 Gew.% der Flüssigkeit.
Es werden dafür ein oder mehrere Alkyläther mehrwertiger Alkohole verwendet. Alkyläther alipha- tischer mehrwertiger Alkohole, insbesondere die Monoalkyläther, werden bevorzugt. Die Monoalkyl- äther von Glykol und Diglykol sind ganz besonders geeignet.
Beispiele geeigneter Äther sind Monoäthyläther, Monopropyläther, Mono-n-butyläther, Monoisobutyl- äther, Mono-tert.-butyläther, Monohexylbutyläther von Äthylenglykol, der Monoisoamyläther von Pro- pylenglykol, der Monomethyläther von Diäthylen- glykol, Monoäthyläther von Diäthylenglykol,
Mono- n-propyläther von Diäthylenglykol, Monoisopropyl- äther von Diäthylenglykol, Monobutyläther von Di- äthylenglykol, Monodecyläther von Diäthylenglykol, Monoäthyläther von Dipropylenglykol, Monoisopro- pyläther von Dipropylenglykol,
Monoisoamyläther von Dipropylenglykol, Monoisopropyläther von Di- isobutylenglykol, Monoäthyläther von Äthylenpro- pylenglykol, Monoisopropyläther von Äthyleniso- butylenglykol.

Fluid suitable as a lubricant and power transmission The present invention relates to a fluid which can be used for lubrication purposes and for mechanical power transmission. Such liquids are used in particular for braking devices as well as suspension or storage and steering devices in vehicles equipped with motors and for transmissions.
For liquids of this type to work satisfactorily under the application conditions, they must have good lubricating properties over a wide temperature and pressure range. They also need to have a suitable viscosity. A highly viscous liquid avoids excessive leakage or sliding in hydraulic pumps, but it shows a high resistance to movement and thus causes high power consumption. On the other hand, liquids of very low viscosity flow rapidly; however, they encourage excessive licking and produce poor effects. In many cases, viscosities of about 12 to 13 centistokes at 50 are required.
Hydraulic fluids must be usable over a very wide temperature range. They must therefore have a high viscosity index, i.e. show a slight shift in viscosity with changes in temperature. They must not freeze out or solidify even in very low winter temperatures. Their boiling point must be high enough so that they do not evaporate during use. It also requires a high flash point and some tolerance to water. Chemically, the liquid should be practically inert to the substances from which the various parts of a hydraulic system are made.
For example, the liquid must not contain any substances that corrode metals, and it must not attack rubber. A known type of fluid of this type consists of a lubricating component and a diluting component.
A specific example of a liquid of this type contains about 50 vol. O / o castor oil and about 50 vol. O / o diacetone alcohol. In other liquids of this type other compounds are used as the lubricating element, such as the esters of ricinoleic acid or polypropylene glycol, or other alcohols or ethers in the diluent, or the lubricant and the diluting elements are mixed in ratios other than 50:50.
However, it is very difficult to achieve an optimal combination of properties, and so far it has not been possible to produce a liquid which at the same time meets the very strict requirements in all respects. It is an aim of the present invention to solve this problem in an internally satisfactory manner.
The liquid according to the present invention also contains lubricating and thinning components. Ingredients that act as lubricants: An essential component is obtained by heating castor oil until it has a viscosity between 20 and 600 poise at 20. The castor oil is heated to a relatively low temperature so that it has an acid number below 20 and preferably below 5. The castor oil will likely polymerize as it is heated. This product is hereinafter referred to as modified castor oil.
In order to obtain a liquid with high resistance to water, that is to say in order to achieve that the liquid can absorb relatively large amounts of water without phase separation occurring, the castor oil can be oxidized during heating, e.g. B. by bubbling air or some other oxygen-containing gas through the oil. It appears that oxygen bridges are formed between the double bonds of ricinoleic acid and that polymerization occurs as a result.
As a further lubricating component, the liquid according to the invention contains a liquid polyoxyalkylene, preferably of the formula R17 O- [R20] ri R3. In this formula, R1 and R3 each denote a hydrogen atom or a hydrocarbon radical (preferably aliphatic) or an acyl group. R2 denotes an alkylene radical and n an integer.
In the polyoxyalkylene chain - [R20] ri, the R2 radical can mean any alkylene radical, preferably an alkylene radical having 2 to 8 carbon atoms.
The polyoxyalkylene chain - [R20] ri can contain alkylene radicals which have a different number of carbon atoms. For example, this chain can contain oxyethylene and oxypropylene radicals.
If the polyoxyalkylene chain contains various alkylene radicals, these can be distributed arbitrarily over the molecule or arranged in regularly repeating units or blocks, each of which consists of one or more similar oxyalkylene radicals.
The polyoxypropylene glycols are particularly suitable for use in liquids according to the present invention.
Preferred polyoxyalkylenes have molecular weights between 800 and 4000 or, particularly advantageously, between 1000 and 3000. Polyoxypropylene glycols with a molecular weight of about 2000 are extremely effective.
Instead of or in connection with the polyoxyalkylenes, neutral esters of aliphatic dicarboxylic acids can be used, preferably those of the formula WOOC - R - COOR ", in which R is a divalent, saturated aliphatic hydrocarbon radical and R 'and R" are alkyl, aralkyl - Or cycloalkyl radicals which contain more than two carbon atoms.
The esters are preferably derived from saturated aliphatic dicarboxylic acids, e.g. B. of malon, ethyl malon, amber, methyl amber, 1,1- or 1,2-diethyl amber, glutar, 1- or 2 methyl-glutar, 1,3-diethyl-glutar -, adipine-1 or 2-methyladipine, pimeline, 1,2,5-trimethyl-pimeline, suberine, azelaine,
Sebacic, nonane, 1,9-dicarboxylic and decane-1,10-dicarboxylic acid, and preferably propanols, butanols, hexanols, octanols and nonanols, or aralkanols, e.g. B. benzyl and phenylethyl alcohol, or cycloalkanols, e.g.
B. cyclopentanol, cyclohexanol and methylcyclohexanol. Examples of suitable liquid esters are di- (2-methyl-heptyl) adipate, di- (3,5,5-trimethylhexyl) adipate or di- (3,5,5-trimethyl sebacate) -hexyl) ester, adipic acid di- (3-ethyl-hexyl) -ester or sebacic acid-di- (3-ethyl-hexyl) -ester, penelic acid-di-hexyl ester, sebacic acid-di- (2-ethyl-hexyl) ) ester, di-sec-butyl sebacate,
Malonic acid di-sec-butyl ester, azelaic acid di (1-ethylpropyl) ester and malonic acid dibutylethyl ester. In order to obtain a liquid with high water resistance, the use of a polyoxyalkylene liquid is preferable to the use of a neutral ester of an aliphatic dicarboxylic acid.
Diluting components: Their proportion is 35 to 70% by weight, preferably 40 to 60% by weight of the liquid.
One or more alkyl ethers of polyhydric alcohols are used for this. Alkyl ethers of aliphatic polyhydric alcohols, in particular the monoalkyl ethers, are preferred. The monoalkyl ethers of glycol and diglycol are particularly suitable.
Examples of suitable ethers are monoethyl ether, monopropyl ether, mono-n-butyl ether, monoisobutyl ether, mono-tert-butyl ether, monohexylbutyl ether of ethylene glycol, the monoisoamyl ether of propylene glycol, the monomethyl ether of diethylene glycol,
Mono-n-propyl ether of diethylene glycol, monoisopropyl ether of diethylene glycol, monobutyl ether of diethylene glycol, monodecyl ether of diethylene glycol, monoethyl ether of dipropylene glycol, monoisopropyl ether of dipropylene glycol,
Monoisoamyl ether of dipropylene glycol, monoisopropyl ether of diisobutylene glycol, monoethyl ether of ethylene propylene glycol, monoisopropyl ether of ethylene isobutylene glycol.
The following list shows favorable proportions (by weight) for the various components of the liquid.
