Definitions

  • the invention relates to flame-retardant hydraulic fluids that are environmentally compatible and have lubricating properties.
  • Hydraulic fluids based on mineral oils are particularly common. In the mining industry, however, flame-retardant hydraulic fluids are required for safety reasons. B. in Schrämm machines, tunnel boring machines, turbo couplings and hydraulic rams. Flame-retardant liquids are also preferred outside of mining wherever there are devastating fires when flammable media escape from the closed hydraulic system.
  • the current flame-retardant hydraulic fluids are, in particular, aqueous systems, either oil-in-water emulsions (HFA) or glycol-polyglycol-water mixtures (HFC).
  • HFA oil-in-water emulsions
  • HFC glycol-polyglycol-water mixtures
  • the main disadvantage of the o / w emulsions is that they are metastable systems, which can be particularly critical due to temperature fluctuations and electrolytes (DE-OS 35 08 946). If thickened systems are involved, such as the avoidance of leakage losses in the gap seals of pumps and valves or the build-up of lubricating films between rubbing solid surfaces, the polymers used are usually not or only insufficiently stable under shear.
  • HFC fluids based on mono-, oligo- or polyglycols have, in addition to extensive flame resistance, the advantage of physiological harmlessness and ecological acceptance (P. Lehringer, Petroleum and Coal-Natural Gas-Petrochemicals 41, 230 (1988)), which is particularly advantageous for Mobile use is where hydraulic fluid leaks often seep into the ground.
  • the systems are also considered to be largely shear stable, but this is to be viewed critically in view of the fact that usually the polymers in particular make the greatest contribution to the overall viscosity of the liquid, because of their chemical structure they are most at risk of shear.
  • Another disadvantage of the current HFC liquids is that the proportion of active substance must be very high, even at a somewhat elevated temperature still have a minimum viscosity. Water contents ⁇ 50% are quite typical here (C. Rasp, Tribologie Schmtechnikstechn. 35, 185 (1988).
  • the additive packages for producing more favorable effects in lubrication and wear protection are very complex here.
  • the task was therefore to develop flame-retardant, environmentally compatible hydraulic fluids which are sufficiently viscous at low active substance concentrations and have a favorable lubricating effect.
  • alkylpolyglycosides even at lower concentrations, alone or in the presence of other surfactants, have a particularly high level of viscosity with a very good lubricating effect.
  • the alkyl oligoglycosides used in accordance with the invention can be prepared entirely or partially on the basis of renewable raw materials by known processes. For example, dextrose is reacted with n-butanol to give butyl oligoglycoside mixtures in the presence of an acid catalyst, which are transglycosidated with long-chain alcohols in the presence of an acid catalyst to give the desired alkyl oliglycoside mixtures.
  • the formula of the products can be varied within certain limits.
  • the alkyl radical R ' is determined by the choice of the long-chain alcohol.
  • the industrially accessible tenside alcohols with 8 to 18 carbon atoms e.g. B. oxo alcohols, Ziegleralkohole and native alcohols from the hydrogenation of fatty acids or fatty acid derivatives.
  • the oligoglycosyl radical Z n is determined, on the one hand, by the selection of the carbohydrate and, on the other hand, by setting the average degree of oligomerization n. B. according to DE-OS 19 43 689.
  • polysaccharides, oligosaccharides and monosaccharides e.g. B. starch, maltodextrins, dextrose, galactose, mannose, xylose, etc. can be converted to alkyl oligoglycosides.
  • the industrially available carbohydrates starch, maltodextrins and dextrose are particularly preferred.
  • alkyl polyglycosides are always mixtures of oligomers, which in turn represent a mixture of different isomeric forms. They exist side by side with ⁇ - and ⁇ -glycosidic bonds in pyranose and furanose form. The links between two saccharide residues are also different.
  • the alkyl polyglycosides can also contain accompanying substances such as residual alcohols, monosaccharides, oligosaccharides and oligoalkyl polyglycosides.
  • cationic surfactants such as quaternary ammonium compounds as additives to alkyl polyglycosides in aqueous hydraulic fluids also have beneficial effects, e.g. B. a strong improvement in lubricating properties.

Description

  • Die Erfindung betrifft schwerentflammbare, Hydraulikflüssigkeiten, die umweltverträglich sind und schmierende Eigenschaften haben.
  • Gebräuchlich sind besonders Hydraulikflüssigkeiten auf Mineralölbasis. Im Bergbau jedoch werden aus Sicherheitsgründen schwerentflammbare Druckflüssigkeiten benötigt, die dort mannigfaltige Anwendung z. B. in Schrämm-Maschinen, Streckenvortriebsmaschinen, Turbokupplungen und Hydraulikstempeln finden. Aber auch außerhalb des Bergbaus werden schwerentflammbare Flüssigkeiten überall dort bevorzugt, wo es bei Austritt brennbarer Medien aus dem geschlossenen Hydrauliksystem zu verheerenden Bränden kommen kann.
  • Die derzeitigen schwerentflammbaren Hydraulikflussigkeiten sind insbesondere wäßrige Systeme, entweder Öl-in-Wasser-Emulsionen (HFA) oder Glycol-Polyglycol-Wasser-Mischungen (HFC). Der Hauptnachteil der o/w-Emulsionen ist der, daß es sich um metastabile Systeme handelt, was insbesondere durch Temperaturschwankungen und Elektrolyte kritisch werden kann (DE-OS 35 08 946). Handelt es sich um verdickte Systeme, wie es die Vermeidung von Leckverlusten in den Spaltdichtungen von Pumpen und Ventilen bzw. der Aufbau von schmierenden Filmen zwischen reibenden Festkörperoberflächen voraussetzen, sind die hierbei eingesetzten Polymere gewöhnlich nicht oder nur unzureichend scherstabil.
  • HFC-Fluide auf der Basis von Mono-, Oligo- bzw. Polyglycolen besitzen neben weitgehender Schwerbrennbarkeit den Vorteil physiologischer Unbedenklichkeit und ökologischer Akzeptanz (P. Lehringer, Erdöl und Kohle-Erdgas-Petrochemie 41, 230 (1988)), was besonders vorteilhaft beim mobilen Einsatz ist, wo Druckflüssigkeitsleckagen häufig im Erdreich versickern. Die Systeme gelten auch als weitgehend scherstabil, was jedoch kritisch zu sehen ist im Hinblick darauf, daß gewöhnlich besonders die Polymeren den höchsten Beitrag zur Gesamtviskosität der Flüssigkeit erbringen, die aufgrund ihrer chemischen Struktur am stärksten schergefährdet sind. Ein weiterer Nachteil der derzeitigen HFC-Flüssigkeiten besteht darin, daß der Anteil an Wirksubstanz sehr hoch liegen muß, um auch bei etwas erhöhter Temperatur noch eine Mindestviskosität zu besitzen. Wassergehalte ≦ 50 % sind hier durchaus typisch (C. Rasp, Tribologie Schmierungstechn. 35, 185 (1988). Außerdem sind die Additivpakete zur Erzeugung günstigerer Wirkungen bei der Schmierung und beim Verschleißschutz hier sehr komplex.
  • Es bestand daher die Aufgabe, schwerentflammbare, umweltverträgliche Hydraulikflüssigkeiten zu entwickeln, die bei niedriger Wirkstoffkonzentration genügend viskos sind und günstige Schmierwirkung zeigen.
  • Die Aufgabe wurde durch wäßrige Hydraulikflüssigkeiten gelöst, die als Basis eine wäßrige Tensidlösung enthalten.
  • Gegenstand der Erfindung ist daher die Verwendung einer Mischung aus
    5 - 30 Gew.-% Alkylpolyglycosid
    0 - 20 Gew.-% tensidischen Additiven
    0 - 10 Gew.-% nichttensidischen Additiven und
    Wasser ad 100 Gew.-%,
    als wäßrige Hydraulikflüssigkeiten, dadurch gekennzeichnet, daß das Alkylpolyglycosid der Formel R-O-Zn entspricht, in der R für einen linearen oder verzweigten, gesättigten oder ungesättigten Alkylrest mit 8 bis 18 Kohlenstoffatomen und Zn für einen Oligoglycosidrest mit im Mittel n = 1 bis 3 Hexose- oder Pentoseeinheiten oder Gemische davon steht und wobei der Wirkstoffgehalt maximal 40 Gew.-% beträgt.
  • Es wurde überraschend gefunden, daß Alkylpolyglycoside schon bei niedrigeren Konzentrationen alleine oder auch in Gegenwart anderer Tenside ein besonders hohes Viskositätsniveau aufweisen, bei gleichzeitig sehr guter Schmierwirkung.
    • Alkylpolyglycoside
  • Die erfindungsgemäß eingesetzten Alkylpolyglycoside entsprechen der allgemeinen Formel (I)

            R-O-Zn,   (I)


    in der R für einen linearen oder verzweigten, gesättigten oder ungesättigten Alkylrest mit 8 bis 18 Kohlenstoffatomen und Zn für einen Oligoglycosidrest mit im Mittel n = 1 bis 3, Hexose- oder Pentoseeinheiten oder Gemische davon steht.
  • Die erfindungsgemäß eingesetzten Alkyloligoglycoside können nach bekannten Verfahren ganz oder teilweise auf Basis nachwachsender Rohstoffe hergestellt werden. Beispielsweise wird Dextrose in Gegenwart eines sauren Katalysators mit n-Butanol zu Butyloligoglycosidgemischen umgesetzt, welche mit langkettigen Alkoholen ebenfalls in Gegenwart eines sauren Katalysators zu den gewünschten Alkyloliglycosidgemischen umglycosidiert werden. Die Formel der Produkte ist in bestimmten Grenzen variierbar. Der Alkylrest R' wird durch die Auswahl des langkettigen Alkohols festgelegt. Günstig aus wirtschaftlichen Gründen sind die großtechnisch zugänglichen Tensidalkohole mit 8 bis 18 C-Atomen, z. B. Oxoalkohole, Ziegleralkohole und native Alkohole aus der Hydrierung von Fettsäuren bzw. Fettsäurederivaten.
  • Der Oligoglycosylrest Zn wird einerseits durch die Auswahl des Kohlenhydrats und andererseits durch die Einstellung des mittleren Oligomerisationsgrades n z. B. nach DE-OS 19 43 689 festgelegt. Im Prinzip können bekanntlich Polysaccharide, Oligosaccharide und Monosaccharide z. B. Stärke, Maltodextrine, Dextrose, Galaktose, Mannose, Xylose usw. zu Alkyloligoglycosiden umgesetzt werden. Besonders bevorzugt sind die großtechnisch verfügbaren Kohlenhydrate Stärke, Maltodextrine und Dextrose. Da die wirtschaftlich interessanten Alkylpolyglycosidsynthesen nicht regio- und stereoselektiv verlaufen, sind die Alkylpolyglycoside stets Gemische von Oligomeren, die ihrerseits Gemisch verschiedener isomerer Formen darstellen. Sie liegen nebeneinander mit α- und β-glycosidischen Bindungen in Pyranose- und Furanoseform vor. Auch die Verknüpfungsstellen zwischen zwei Saccharidresten sind unterschiedlich.
  • Synthesebedingt können die Alkylpolyglycoside auch Begleitsubstanzen wie Restalkohole, Monosaccharide, Oligosaccharide und Oligoalkylpolyglycoside enthalten.
    • Tensidische Additive
  • Die erfindungsgemäßen schwerentflammbaren Hydraulikflüssigkeiten können ferner bis zu 20 Gew.-% tensidische Additive enthalten, die aus den nachfolgenden Verbindungen ausgewählt sind oder aus Mischungen dieser Verbindungen bestehen:
    • a) Alkylbenzol- oder Dialkylbenzolsulfonate der Formel (II)

              R(R₁)C₆H₃SO₃M   (II),

      in der R einen verzweigten oder unverzweigten Alkylrest mit 8 bis 20 C-Atomen, R₁ H oder einen verzweigten oder unverzweigten Alkylrest mit 1 bis 10 C-Atomen, wobei die Kohlenstoffatomsumme von R und R₁ mindestens 8, vorzugsweise 10 bis 18, beträgt, und M Na, K, Ammonium oder Alkylammonium bedeuten.
    • b) Alkansulfonate und/oder Olefinsulfonate der Formel (III)

              R''SO₃M'   (III)

      sein, in der R'' ein gesättigter oder ungesättigter, verzweigter oder unverzweigter Alkylrest mit 8 bis 20 C-Atomen und M' Na, K, Ammonium oder Alkylammonium bedeuten.
    • c) Petroleumsulfonate
    • d) Fettalkohol- bzw. Alkylphenolderivate der folgenden Formel (IV)

              [R‴(C₆H₄)xO(R''''O)y]z UvM'',   (IV)

      in der R‴ ein gesättigter, verzweigter oder unverzweigter Alkylrest mit 6 bis 20, vorzugsweise 8 bis 16 Kohlenstoffatomen, x = 0 oder 1, R'''' C₂H₄ oder C₃H₆, y 0 bis 15, z 1 oder 2, U SO₃, CH₂COO, CHCOO, v 0 oder 1 und M'' H, Na, K, Ammonium oder Alkylammonium bedeuten.
    • e) Weitere tensidische Zusätze sind Carbonsäuren mit längeren, verzweigten oder unverzweigten, gesättigten oder ungesättigten Kohlenwasserstoffketten sowie Phosphorsäurepartialester insbesondere von Alkoholen bzw. von Fettalkohol- bzw. Alkylphenoloxethylaten. Letztere lassen sich durch Umsetzung der betreffenden Alkohole bzw. Oxethylate mit Phosphorsäuren, Phosphoroxiden oder Phosphorhalogeniden herstellen.
  • Schließlich zeigen auch kationische Tenside wie quaternäre Ammoniumverbindungen als Zusätze zu Alkylpolyglycosiden in wäßrigen Hydraulikflüssigkeiten günstige Wirkungen z. B. eine starke Verbesserung der schmierenden Eigenschaften.
    • Nichttensidische Zusätze
  • Geeignete nichttensidische Zusätze bei den erfindungsgemäßen Hydraulikflüssigkeiten sind Amine bzw. Alkanolamine als pH-Regulatoren bzw. Korrosionsinhibitoren; Natriummolybdat, Borsäureaminester, Benzotrialzol bzw. Toluoltriazol ebenfalls als Korrosionsinhibitoren; Morpholin bzw. N-Methylmorpholin als Dampfphaseninhibitoren; Silikonentschäumer oder andere Entschäumer; Glycol und/oder Glycolether bzw. Harnstoff als Löslichkeitsvermittler und gegebenenfalls wasserlösliche Polymere zur Korrektur des Temperaturprofils der Viskosität sowie Konservierungsmittel.
  • Basis der erfindungsgemäßen Hydraulikflüssigkeit neben Wasser als Lösemittel sind die Alkylpolyglycoside, eine toxikologisch, umbedenkliche Tensidklasse von hervorragender biologischer Abbaubarkeit (95 bis 97 Gew.-% Coupled Unit-Test, DOC). 3 bis 30 Gew.-%, vorzugsweise 5 bis 25 Gew.-%, Alkylpolyglycosid sind in den erfindungsgemäßen Flüssigkeiten enthalten, wobei die Gesamtwirkstoffkonzentration bei max. 40 Gew.-%, bevorzugt bei 35 Gew.-%, liegt.
  • Die erfindungsgemäßen Druckflüssigkeiten sind gewöhnlich im Temperaturbereich zwischen 5 und 80 °C klar bzw. evtl. in Gegenwart von Silikonentschäumern schwach opaleszierend. Sie sind gewöhnlich schwach alkalisch eingestellt.

    bedeuten. Beispiel 1
  • Eine 15 Gew.-%ige Lösung von C₁₂C₁₃-Alkylpolyglycosid (D.P. 1.7, bestimmt via ¹H-NMR) in VE-Wasser wurde hergestellt. Das Viskositätsverhalten der Lösung (Rotationsviskosimeter Haake RV 20, M 5, 50 °C, Scherbereich 30-300 sec⁻¹) ist newtonisch und liegt bei ca. 150 mPa·s. Mehrfache jeweils 10minütige Ultrabeschallung (Telsonic USG 1000, 20 kHz) veränderte die Viskosität nicht und bestätigt die vermutete Scherstabilität des Systems. Der Klarpunkt der Lösung liegt bei 10 °C. Mit steigender Temperatur (bis 80 °C) erfährt die Lösung keine optische Veränderung. Das Verschleißverhalten (Schmierwirkung) der Lösung wurde mit der Reibverschleißwaage nach Reichert untersucht (Gewichtsverlust der Prüfrollen nach 100 m Reibungsstrecke und 1 500 g Belastung). Der Mittelwert aus 3 Testläufen betrug 6.6 ± 0.5 mg bei einem spezifischen Flächdruck von 2 400 N/cm². Bei der Verschleißmessung wurde keine Schaumentwicklung beobachtet. Vergleichende Verschleißtests mit VE-Wasser einerseits und Ecubasol Hydrotherm(R) 36 (Hydraulikflüssigkeit auf Glycolbasis) anderseits ergaben unter analogen Bedingungen Gewichtsverlustwerte von 66 bzw. 6.9 mg. Der Vergleich der Ergebnisse demonstriert, daß bereits eine 15 Gew.-%ige Lösung des Alkylpolyglycosids nicht nur ein ausreichendes Viskositätsniveau sondern auch stark schmierende Eigenschaften besitzt.
    • Beispiel 2
  • Eine 15 Gew.-%ige Lösung von N-C₁₂-C₁₈-N, N, N Trimethylammoniumchlorid in VE-Wasser ist bei 50 °C geringviskos (ca. 1 mPa·s), ihre verschleißverhindernde Wirkung - analog Beispiel 1 durchgeführt - ist mit 34,5 mg Gewichtsverlust nur mittelmäßig. Ersetzt man jedoch die Hälfte der quaternären Ammoniumverbindung durch C₁₂C₁₃-Alkylpolyglycosid (D.P. 1.7), so resultiert mit einem Gewichtsverlust von 10,9 ± 0,6 mg eine starke Schmierwirkung, wohingegen die Viskosität in Näherung unverändert bleibt und der Klarpunkt von +2 °C auf +5 °C steigt.
    • Beispiel 3
  • Eine 10 Gew.-%ige Lösung von C₁₀-C₁₄-Alkylpolyglycosid (D.P. ca. 1,3) in VE-Wasser zeigt newton sches Fließverhalten und besitzt bei 50 °C eine Viskosität von 70 mPa·s. Die analog Beispiel 1 durchgeführte Untersuchung des Verschleißverhaltens erbrachte einen Gewichtsverlust des Prüfkörpers von 15 mg.
    • Beispiele 4 bis 13 (Tabellen)
  • Die betreffenden Beispiele demonstrieren die Wirksamkeit der erfindungsgemäßen Mischungen hinsichtlich Viskositätsniveau und Verschleißschutz. Die bei den Lösungen entsprechend Beispiel 4 und 10 durchgeführte Beschallung (2 mal 10 Minuten mit jeweils nachträglicher Viskositätsmessung) zeigt eine vollkommene Scherstabilität der die erhöhte Viskosität erzeugenden Strukturen. Mit den Beispielen 11 und 12 wird die Wirksamkeit der erfindungsgemäßen Mischungen in Wässern unterschiedliche Härte (Calciumhärte) demonstriert.
