Description
Es ist an sich bekannt, Schmierölen auf mineralischer oder synthetischer Basis eine halogenhaltige öllösliche
organische Verbindung einzuverleiben, welche dem Basisöl günstige Hochdruckeigenschaften verleiht.
Derartige Schmieröle eignen sich zur Schmierung bewegter metallischer Flächen unter Druck und
insbesondere zur Schmierung von Dampfturbinen. Leider haben diese halogenhaltigen Schmieröle aber
den Nachteil, daß sie eine Korrosion und Braunfärbung eisenhaltiger Oberflächen begünstigen.
Erfindungsgemäß läßt sich dieser Nachteil beheben, wenn man den Basisölen kleine Mengen einer Mischung
aus einem halogenhaltigen öllöslichen organischen Hochdruckzusatz und aus einer gleichfalls öllöslichen
Organo-Zinn-Verbindung einverleibt, die mindestens eine Kohlenstoff-Zinn-Bindung im Molekül
aufweist. Die hierdurch erzielbaren Vorteile, welche vor allem in einer Herabsetzung der Korrosion
und Fleckenbildung ohne Beeinträchtigung der .sonstigen wertvollen Eigenschaften des Schmieröles,
wie z. B. seiner Dampf-Entemulgierungszahl bestehen,
beruhen wahrscheinlich vor allem auf der Fähigkeit der Organo-Zinn-Verbindung zur Absorption des bei
der praktischen Anwendung des Öls aus der halogenhaltigen organischen Verbindung freigesetzten Halogens.
Es ist bereits vorgeschlagen worden, Zinn-Silicium-Kohlenstoff-Organo-Polysiloxane
als Zusatzstoffe für Hochtemperatur-Schmieröle zu verwenden, um deren Oxydationsbeständigkeit zu erhöhen und gleichzeitig
ihren Reibungskoeffizienten herabzusetzen.
Weiterhin ist es bekannt, Schmierölen spezielle, vom vierwertigen Zinn abgeleitete Thioxanthate und Thiocarbamate
beizumischen, um die Bildung saurer Oxydationsprodukte in hochraffinierten Ölprodukten zu
verringern, welche gegenüber Metallen korrosiv wirken. Hierbei handelt es sich aber nicht um ein Zusammenwirken
mit halogenhaltigen Hochdruckzusatzstoffen.
Die Schmieröle gemäß der Erfindung sind besonders geeignet zum Schmieren von Dampfturbinen. Sie
sind jedoch auch in entsprechender Weise anwendbar bei anderen Schmierungsaufgaben, bei welchen hohe
Drücke zwischen den beweglichen Teilen auftreten, z. B. bei Verbrennungskraftmaschinen und Kraftübertragungsgetrieben.
Das als Basis verwendete Schmieröl kann jedes natürliche oder synthetische Schmieröl sein, das für
die in Betracht kommende Anwendung brauchbar ist. Es können mineralische Schmieröle mit einer Viskosität
von 40 bis 2000 SUS, insbesondere von 40 bis 400 SUS, bei 37,8° C verwendet werden. Diese mineralischen
Schmieröle können aus den verschiedensten Roherdölen erhalten worden sein, z. B. aus naphthe-

nischen, paraffinischen oder asphaltischen Rohölen. Es können auch Gemische aus mineralischen Schmierölen
und fetten Ölen, wie Ricinusöl und Specköl, oder auch synthetische Schmieröle und Gemische aus synthetisehen
Schmierölen mit mineralischen und bzw. oder fetten ölen verwendet werden. Geeignete synthetische
Schmieröle werden z. B. durch Polymerisieren von Olefinen oder durch Alkylierung aromatischer Kohlenwasserstoffe
mit Olefinen bzw. Alkylhalogeniden in Anwesenheit eines Friedel-Crafts-Katalysators erhalten.
Auch organische Ester-Schmieröle, wie Sebazinsäure- oder Adipinsäure-di-(2-äthylhexyl)-ester sowie
Trioctyl- oder Trikresylphosphat und Tetraoctylsilikate, sind als Basisöle brauchbar. Meistens liegt das
Basis-Schmieröl in einer Menge über 90 Gewichtsprozent und häufig sogar in einer Menge von 95 oder
mehr Gewichtsprozent, berechnet auf das gesamte Schmieröl, vor.
Als öllösliche, halogenhaltige organische Verbindung wird im Rahmen der Erfindung vorzugsweise
eine halogenierte Erdölfraktion, wie Schmieröle und Paraffine, eingesetzt. Die Halogenierung erfolgt dabei
so weit, daß mindestens 2 Halogenatome im Molekül enthalten sind, im allgemeinen bis zu einem Halogengehalt
von 20 bis 70 Gewichtsprozent. Ein besonders geeignetes Ausgangsmaterial hierfür ist ein Paraffinwachs
mit einem Schmelzpunkt von 38 bis 54,5° C, welches vorzugsweise bis zu einem Chlorgehalt von
30 bis 50 Gewichtsprozent und insbesondere über
109 578/390
40 Gewichtsprozent chloriert wird. Andere geeignete halogenierte Zusatzstoffe sind die halogenierten Fettsäuren,
wie Chlorstearinsäuren und chlorierte fette öle und Fette, die mindestens 2 Chloratome im Molekül
enthalten. Es können auch halogenierte aromatische Verbindungen verwendet werden, wie chloriertes
Diphenyl, chlorierte Diphenyläther und chloriertes Napthalin, welche jeweils mindestens 2 Chloratome im
Molekül enthalten, sowie 1,1,1 -Trichlor- 2,2- bis-(4'-chlorphenyl)
-äthan.
Andere geeignete halogenhaltige Zusatzstoffe werden in den beiden britischen Patentschriften 622 311
und 640 530 beschrieben.
Die organische Zinnverbindung, die gemäß vorliegender Erfindung zur Herabsetzung der von dem
gleichzeitigen Gehalt an der halogenhaltigen organischen Verbindung herrührenden Korrosivität der
Schmieröle verwendet wird, soll mindestens eine Kohlenstoff-Zinn-Bindung im Molekül und vorzugsweise
zwei oder mehr solcher Bindungen pro Zinnatom (falls das Molekül mehr als 1 Zinnatom enthält)
aufweisen und in dem verwendeten Basisschmieröl löslich sein. In der betreffenden Verbindung können
also zwei oder mehr der vier Zinnvalenzen durch Alkyl- oder Arylreste von geeignetem Molgewicht abgesättigt
sein, während der Rest (falls vorhanden) der Valenzen in anderer Weise abgesättigt ist, vorzugsweise
durch Reste, die im Sinne einer Verbesserung der Öllöslichkeit wirken, z. B. Fettsäurereste mit 8 bis
20 Kohlenstoffatomen. Beispiele solcher Zinnverbindungen sind Di-n-benzylthiozinn-di-n-octyl-, Di-n-butylzinndilaureat
und andere Reaktionsprodukte der Dialkylzinnoxyde mit Alkoholen von geeignetem Molgewicht, z. B. n-Hexanol, Benzylalkohol und Octadecylalkohol.
Diese Verbindungen können in Mengen von 0,01 bis etwa 1 Gewichtsprozent oder darüber und
vorzugsweise in Mengen von 0,02 bis 0,5 Gewichtsprozent verwendet werden, oder sie werden in solchen
Mengen eingesetzt, daß das fertige Schmieröl einen Zinngehalt von 0,002 bis 0,2 °/o oder darüber, vorzugsweise
0,05 bis 0,1%, aufweist.
Zusätzlich können die erfindungsgemäßen Schmieröle auch noch andere an sich bekannte Bestandteile enthalten,
um spezielle Eigenschaften für besondere Anwendungszwecke zu erzielen. Solche weitere Zusatzstoffe
umfassen Reinigungsmittel, Stockpunktserniedriger, Verbesserungsmittel für den Viskositätsindex,
Antioxydationsmittel, rosthindernde Verbindungen und schaumhindernde Mittel.
Geeignete Reinigungsmittel sind z. B. die öllöslichen Salze von verschiedenen Fettsäuren mit 10 bis
30 Kohlenstoffatomen von Wollfettsäuren, von Paraffinwachs abgeleiteten Säuren (hergestellt durch Oxydation
von Paraffin) von chlorierten Fettsäuren, Harzsäuren, aromatischen Carbonsäuren einschließlich der
Fettsäuren mit einem aromatischen Substituenten, von Sulfonsäuren, von Phosphorsäure-, Arsen- und Antimonsäure-mono-
und -diestern, einschließlich der entsprechenden Thiosäureester, sowie ferner von Estern
der Phosphon- und der Arsensäure. Ausgezeichnete metallische Reinigungsmittel für die Zwecke der vorliegenden
Erfindung sind die Calciumsalze öllöslicher Erdölsulfonsäuren. Diese können zweckmäßig in
Mengen von etwa 0,025 bis 0,2% Sulfatasche vorliegen.
Geeignete Antioxydationsmittel sind z. B. Alkylphenole, Aminophenole und Amine.
Als rosthindernde Mittel können z. B. die Dicarbonsäuren mit 16 oder mehr Kohlenstoffatomen, die Alkali-
und Erdalkalisalze von Sulfonsäuren oder Fettsäuren sowie mehrwertige Metallsalze von Alkylphenolkondensationsprodukten
verwendet werden.
Die Schmieröle gemäß der Erfindung können ferner außer den halogenhaltigen organischen Verbindungen
noch andere bekannte Hochdruckzusatzmittel enthalten, z. B. Ester von phosphorhaltigen Säuren, neutrale
aromatische Schwefelverbindungen mit verhältnismäßig hohen Siedetemperaturen, wie Diarylsulfide,
sulfonierte fette Öle oder ungesättigte Fettsäuren, wie
ίο sulfurierte Öl-, Linol-, Eruka-, Linolen- und Ricinolsäure,
sulfurierte Ester aus Fettsäuren und einwertigen Alkoholen sowie sulfurierte langkettige Olefine
und sulfurierte, phosphorierte fette öle oder Säuren. Je nach der Art des Zusatzstoffes und nach den Bedingungen,
unter welchen das Gemisch verwendet werden soll, kann die Menge dieser weiteren Zusatzstoffe
bis zu 2 Gewichtsprozent oder darüber (berechnet auf das Gesamtgemisch) betragen.
In den folgenden Beispielen sind die angegebenen Teile Gewichtsteile.
Ein für die Schmierung von Dampfturbinen vorzüglich geeignetes Schmieröl wurde hergestellt durch
Vermischen der folgenden Komponenten:
74 Teile eines lösungsmittelraffinierten und mit Bleicherde behandelten mineralischen
Schmieröls mit einer Viskosität Redwood 1 von 160 Sekunden bei 60° C;
20 Teile eines ähnlichen Öls mit einer Viskosität Redwood 1 von 65 Sekunden bei 60° C;
20 Teile eines ähnlichen Öls mit einer Viskosität Redwood 1 von 65 Sekunden bei 60° C;
5 Teile chloriertes Paraffin (42 Gewichtsprozent Chlor) ;
0,4 Teile 2,6-Ditert.butyl-4-methylphenol;
0,02 Teile des Reaktionsproduktes aus Maleinsäureanhydrid und gespaltenen P araffinolefinen;
0,06 Teile sulfurierte Ölsäure;
0,5 Teile Dibutylzinndilaureat.
Es hatte einen kinematischen Viskositätsindex von 103 und eine Viskosität von 10 cSt bei 98,9° C bzw.
von 87 cSt bei 37,8° C.
Dieses Öl wurde einer vergleichenden Prüfung mit einem ähnlichen öl unterworfen, welches aber die
organische Zinnverbindung nicht enthielt. Es wurden Probestücke von handelsüblichem Weichstahl
(25,4-25,4-1,59 mm) mit Schmirgelpapier poliert und jeweils in ein Gemisch von 45 ecm öl und 5 ecm
Wasser in einem 100-ccm-Becher eingetaucht, so daß die untere Hälfte über der Flüssigkeitsfläche blieb.
Die Becher wurden in einen Ofen gebracht, der auf 98 ±1° C gehalten wurde, und in Abständen geprüft,
wobei erforderlichenfalls Wasser ergänzt wurde.
Das Probestück in dem Öl, ohne Zusatz einer organischen Zinnverbindung, zeigte nach 3 Tagen Rostflecken,
während die Probe im Öl gemäß dem vorliegenden Beispiel selbst nach 4 Monaten keinen Rost
aufwies. Bei dem Dampf-Desemulgierungstest (IP 19) ergab das Öl gemäß vorliegendem Beispiel eine Entemulgierungszahl
von 220 Sekunden gegenüber 215 Sekunden bei dem Vergleichsöl. Eine solche Differenz
liegt innerhalb der Fehlergrenzen des Versuchs. Nach dem ASTM-Test D 943-54 »Oxidation Characteristics
of Inhibited Steam Turbine Oils« wies das Öl nach dem Beispiel eine Lebensdauer von mehr als 3000 Stunden
auf, die sich vorteilhaft unterschied gegenüber einer Lebensdauer von nur 1500 bzw. 2000 Stunden,
wie sie von üblichen guten Dampfturbinenölen gefordert werden kann.
Ein Öl von ähnlicher Zusammensetzung, wie im Beispiel 1 beschrieben, welches aber nur 0,05 %
Di-n-butylzinndilaureat und keine sulfurierte Ölsäurekomponente
enthielt, hatte ähnliche günstige physikalische Eigenschaften. Es ergaben sich auch ähnliche
Resultate bei dem Plattentest im Ofen, wie er vorstehend beschrieben ist, und bei dem Dampf-Entemulgierungstest
(IP 19). Dieses Öl wurde einer Prüfung im Vierkugelapparat (20 kg Belastung während 100 Minuten) und einer Timken-Belastungsprüfung
(2,268 kg während 30 Minuten) unterworfen, wobei als Vergleichssubstanz das im Beispiel 1 erwähnte
Ölgemisch ohne den Zusatz der zinnorganischen Verbindung diente. Es zeigte sich kein nennenswerter
Unterschied in den Hochdruckeigenschaften gegenüber dem Vergleichsöl; dagegen war aber seine
Beständigkeit gegenüber dem Rosten beim Auftragen auf eine Stahlplatte und bei Einwirkung eines Dampfstrahls
vorzüglich.
Es wurde ein Schmieröl für Dampf turbinen und von ähnlicher Zusammensetzung wie im Beispiel 2 hergestellt,
aber unter Zusatz von nur 0,03 Teilen sulfurierter ölsäure, was also der halben im Beispiel 1 verwendeten
Menge entspricht.
Es wurde ein Schmieröl hergestellt durch Mischen der folgenden Komponenten:
94 Teile lösungsmittelraffiniertes und mit Bleicherde behandeltes mineralisches Schmieröl
mit einer Aiskosität von Redwood 1 bei 60° C von 160 Sekunden;
4,4 Teile chloriertes Diphenyl (48 Gewichtsprozent Chlor) ;
0,4 Teile 2,6-Ditert.butyl-4-methylphenol;
0,02 Teile des Reaktionsproduktes aus Maleinsäureanhydrid und gespaltenem Wachsolefin;
0,06 Teile sulfurierte Ölsäure;
0,2 Teile Di-(benzylthio)-zinndi-n-octyl).
Das Zinndibutyldilaureat des Öls gemäß Beispiel 1 wurde ersetzt durch eine gleiche Menge Di-(benzyl thio)-zinndioctyl.
Die Entemulgierungszahl des so erhaltenen Öls betrug 220 Sekunden.
Eine Zinnverbindung mit beschränkter Öllöslichkeit wurde hergestellt durch Umsetzen von 10 Teilen Dioctylzinnoxyd
mit 5,65 Teilen n-Hexanol. Die Reaktion wurde durchgeführt in einer Benzollösung unter
azeotropischer Abtrennung des Reaktionswassers.
Zu den Ölbestandteilen gemäß Beispiel 1 wurde ein Überschuß der erhaltenen Verbindung zugesetzt, und
nach Erwärmen wurde das Öl nitriert. Es besaß einen Zinngehalt von 0,015%. Die restlichen Bestandteile
gemäß Beispiel 1 (mit Ausnahme des Dibutylzinndilaureats) wurden anschließend zugegeben, worauf
das fertige Öl eine Entemulgierungszahl von 260 Sekunden besaß.
Das n-Hexanol nach Beispiel 6 wurde ersetzt durch 6,7 Teile Benzylalkohol, wodurch ein Öl erhalten
wurde mit einem Zinngehalt von 0,043%. Die Entemulgierungszahl des erhaltenen Öls betrug 225 Sekunden.
