Um den Anforderungen der modernen Technik an Hochtemperaturschmierfetten zu genügen, welche ihre
Konsistenz und Schmierfähigkeit auch bei Arbeitstemperaturen zwischen 200 und 2500C während der
praktisch in Betracht kommenden Zeiträume beibehalten müssen, hat man bereits spezielle organische Verbindungen
und Pigmente aus der Klasse der Indogenverbindungen, Phthalocyaniverbindungen, der Antrachinone
und der Azine als Gelierungsmittel eingesetzt. Besonders geeignet für diesen Zweck sind Schmierfette
auf Schmierölbasis, welche als Verdickungsmittel eine wasserunlösliche Verbindung mit zwei Einheiten

im Molekül enthält. Der aus drei Ringen bestehende Rest weist wenigstens ein Carbonylradikal am mittleren
Ring der Gruppe auf.
Diese Verbindungen fallen unter die bekannten »INDANTHREN-Farbstoffe«. Das Wort »INDANTHREN«
ist für die Firma Badische Anilin- und Sodafabrik AG, Ludwigshafen am Rhein, unter der Nummer
51 151 als Warenzeichen geschützt.
Um eine befriedigende Schmierfettkonsistenz mit dieser Art von Verdickungsmittel zu erzielen, müssen
jedoch außergewöhnlich hohe Mengen der betreffenden Stoffe eingesetzt werden, so daß solche Schmierfette
vom wirtschaftlichen Standpunkt aus recht unvorteilhaft sind. Außerdem weisen sie in manchen Fällen den
Nachteil auf, daß die Lebensdauer von damit behandelten Lagern nicht immer ausreichend ist.
Es wurde nun gefunden, daß die Konsistenz von Schmierfetten, welche unter Verwendung der vorstehend
beschriebenen Verbindungen mit Dreiringstruktur, welche wenigstens ein Carbonylradikal am
mittleren Ring aufweisen, oder einer Indogenverbindung oder von n-Acyl-iMO-dihydroxy-M-diaminoanthrazenen,
n-Acyl-iMO-dihydroxy-l^-diaminoanthrazenen,
n-Acyldiaminoanthrachinonen bzw. n-Acylaminophenolen als Gelierungsmittel hergestellt
worden sind, durch die Einarbeitung von 1,5 bis 20 Gewichtsprozent, bezogen auf das gesamte Schmierfett,
eines aliphatischen Kohlenwasserstoffdiamines, vorzugsweise eines Alkandiamines mit weniger als
10 Kohlenstoffatomen im Molekül, wesentlich verbessert werden kann. Äthylendiamin und 1,6-Hexandiamin
sind bevorzugte Vertreter dieser Verbindungs-Donald Edward Loeffler, Walnut Creek, Calif.
(V. St. Α.),
ist als Erfinder genannt worden
ist als Erfinder genannt worden
gruppe. Ein weiterer nicht zu erwartender Vorteil der vorliegenden Erfindung besteht darin, daß die Anwesenheit
eines größeren Anteiles eines Amins in Schmierfetten dieser besonderen Art die Lebensdauer
von Lagern, welche mittels derartiger Schmierfette geschmiert werden, ganz beträchtlich erhöht. Diese Erscheinung
zeigt sich vor allem bei Arbeitstemperaturen oberhalb 149° C.
Ein weiterer wesentlicher Vorteil, der sich erfindungsgemäß erzielen läßt, besteht in der beträchtlichen Verringerung
der Kosten der betreffenden Schmierfette, da es sich bei den betreffenden Aminen um verhältnismäßig
preiswerte Materialien handelt. Daher bedeutet eine Verringerung des Gehaltes des Schmierfettes an
dem Verdickungsmittel infolge des Aminzusatzes eine etwa 20fache Ersparnis hinsichtlich der Kosten für den
Schmierfettverdicker.
Es ist bereits bekannt, an Stelle von Metallseifen auch andere Seifen als Verdickungsmittel für Schmieröl einzusetzen,
insbesondere wenn letztere bestimmte oxydierbare aromatische Erdölfraktionen enthalten, und
zwar von Monoaminen abgeleitete fettsaure Salze. Außerdem kann man zusätzlich spezielle aromatische
Diamine als Antioxydationsmittel mitverwenden, und
209 508/296
weiterhin üben auch gewisse aliphatische Monoamine eine antioxydieren.de Wirkung aus. Über die Eignung
von aliphatischen Kohlenstoffwasserstoffdiaminen als Verdickungsmittel in Kombination mit speziellen, aromatische
kondensierte Ringsysteme aufweisenden Verdickungsmitteln ist aber aus diesem Stand der Technik
nichts bekanntgeworden.
Weiterhin hat man Schmierfette empfohlen, die Acetylenruß als Gelierungsmittel und Amine als
Hochdruckzusatzstoffe enthalten. Für diesen speziellen Zweck kommen aber praktisch nur aromatische Diamine
oder aliphatische Monoamine in Betracht. Dabei ist auch noch zu berücksichtigen, daß die erfindungsgemäß
mitverwendeten aliphatischen Kohlenwasserstoffdiamine an sich gar keine verdickende Wirkung
ausüben, sondern hierzu erst durch die Anwesenheit der vorstehend angeführten speziellen Gelierungsmittel
befähigt werden.
Während der üblicherweise für die Verbesserung der Konsistenz der betreffenden Schmierfette verwendete
Aminanteil zwischen etwa 1,5 und 20 Gewichtsprozent, bezogen auf das Schmierfett, liegt, können die hierfür
geeigneten Mengenverhältnisse auch als Äquivalente des Amins je 100 g des Schmierfettes ausgedrückt
werden. Die größte Wirkung wird erzielt, wenn etwa 0,02 bis 0,1 Äquivalente des Amins je 100 g des
Schmierfettes zur Anwendung kommen.
Geeignete aliphatische Diamine sind beispielsweise:
A. Acyclische Diamine
gen enthält pro Molekül 2 Einheiten der folgenden typischen Gruppierung:
1,3-Diamino-2-äthylpropan
1,4-Diamino-2-propylbutan
1,5-Diamino-3-methylpentan
1,5-Diamino-3-butylpentan
1,6-Diamino-4-äthylhexan
1,4-Diamino-2-propylbutan
1,5-Diamino-3-methylpentan
1,5-Diamino-3-butylpentan
1,6-Diamino-4-äthylhexan
1,1 -Diaminoäthan
1,2-Diaminopropan
1,3-Diaminobutan
1,4-Diaminopentan
1,4-Diamin ohexan
1,4-Diaminoheptan
1,4-Diaminooctan
2,6-Diaminononan
3,6-Diaminodecan
1,2-Diaminopropan
1,3-Diaminobutan
1,4-Diaminopentan
1,4-Diamin ohexan
1,4-Diaminoheptan
1,4-Diaminooctan
2,6-Diaminononan
3,6-Diaminodecan
1,2-Diaminoäthan
1,3-Diaminopropan
1,4-Diaminobutan
1,5-Diaminopentan
1,6-Diaminohexan
1,7-Diaminoheptan
1,8-Diaminooctan
1,9-Diaminononan
1,10-Diaminodecan
1,3-Diaminopropan
1,4-Diaminobutan
1,5-Diaminopentan
1,6-Diaminohexan
1,7-Diaminoheptan
1,8-Diaminooctan
1,9-Diaminononan
1,10-Diaminodecan
Es ist zu beachten, daß dieser aus drei Ringen bestehende Rest wenigstens ein Carbonylradikal am
mittleren Ring der Gruppe aufweist. Einige spezielle Vertreter dieser Gruppe, wie das N-Dihydro-1,2-1',
2'-anthrachinonazin, enthalten sogar zwei Carbonylradikale an dem mittleren Ring. Andere Verbindungen
dieses Typs, beispielsweise das Flavanthron, enthalten nur das eine Carbonylradikal, während die Dreiringgruppe
mit einer zweiten derartigen Gruppe mittels Stickstoffbindungen oder im Falle des Pyranthrons
ao mittels Kohlenwasserstoffbindungen verknüpft ist. Ein
weiteres wesentliches Merkmal dieser Verbindungsgruppe besteht darin, daß der Stickstoff nicht als Kernlement
in denjenigen Ringen vorkommt, welche die ,Jreiringgruppe bilden.
Der wirksamste Verdicker zur Anwendung in Hochtemperaturschmierfetten
gemäß der Erfindung ist die Verbindung N-Dihydro-1,2-1 '^'-anthrachinonazin,
doch können auch andere davon abgeleitete Verbindungen eingesetzt werden. Am besten werden diese
Verdickungsmittel in Mengen zwischen 5 und 35 Gewichtsprozent in ihrer nichtmetallischen Form verwendet,
d. h. ohne daß die Carbonylgruppen in diesen Verbindungen mit Ionen, beispielsweise mit Natrium,
Kalium oder Calcium, neutralisiert worden sind. Im Rahmen der vorliegenden Erfindung lassen sich beispielsweise
auch die folgenden Verbindungen sehr gut verwenden:
Flavanthron
Pyranthron
Violanthron
Pyranthron
Violanthron
3,3 '-Dichlor-N-dihydro-1,2-1 ',2'-anthrachinonazin
Trichlor-N-dihydro-1,2-1 \2'-anthrachinonazin
Eine weitere Gruppe von Verdickungsmitteln, welche
zur Herstellung von Hochtemperaturschmierfetten gemaß
der Erfindung verwendet werden kann, sind die Indogenverbindungen mit der folgenden allgemeinen
Struktur:
B. Alicyclische Diamine
1,2-Diaminocyclohexan
1,4-Diaminocyclohexan
1 -(Aminomethyl)-2-aminocyclohexan
2,2-Diamino-1 -cyclohexylpropan
Die Amine werden vorzugsweise eingearbeitet, indem man sie zusammen mit dem fertigen Schmierfett homogenisiert.
Die Amine können jedoch auch zusammen mit dem Verdickungsmittel zu einem Zeitpunkt zugesetzt
werden, wo das Schmierfett erst aus den übrigen Komponenten hergestellt wird, oder man kann sie in
der Schmierölbasis dispergieren, ehe dieser das Hauptverdickungsmittel
beigemischt wird.
Eine Gruppe der als Gelierungsmittel in den erfindungsgemäßen Schmierfetten verwendeten Verbindun-
C =
NH
NH
R'
In diesen Formeln bedeuten R und R' Aryl- oder Alkylarylreste, welche mit benachbarten Gliedern der
heterocyclischen Ringe durch in Orthosteilung zueinander stehende Bindungen verknüpft sind. Diese Reste
können gleich oder verschieden sein, und es kann sich um monocyclische oder polycyclische Reste handeln,
beispielsweise um Phenylen-, Biphenylen- oder Naphthylengruppierungen. Diese Aryl- oder Alkarylreste
können auch substituiert sein und die verscbiedeaartigsten Substituenten enthalten, wie z. B. Hydroxy-,
Carboxy-, Halogen- oder Stickstoffgruppen. Beispiele für derartige Verbindungen sind Indigo, Isoindigo,
3-Ketoindolin, Isatid und Isatin.
Eine dritte Klasse von geeigneten Verdickungsmitteln
sind die Phthalocyanine, zu denen nicht nur metallfreie, sondern auch metallhaltige Vertreter dieser Stoffklasse
gehören, wie beispielsweise Zink-, Nickel-, Aluminium- und insbesondere Kupferphthalocyanin.
Eine weitere Klasse von schmierfettbildenden Verdickern kann durch die folgende allgemeine Strukturformel
charakterisiert werden:
OH NH2
OH
NH-C—R
In dieser Formel bedeutet R eine Alkylgruppe mit 3 bis 24 Kohlenstoffatomen. Acylderivate, bei denen
der Rest R 12 bis 22 Kohlenstoffatome enthält, werden bevorzugt angewendet.
Acylderivate der erfindungsgemäß in Betracht gezogenen Art können hergestellt werden, indem man
die Verbindung 9,10-Dihydroxy-1,4-diaminoanthrazen
zusammen mit der betreffenden organischen Säure auf Reaktionstemperaturen von etwa 100 bis 25O0C erhitzt.
Als Katalysator kann bei dieser Reaktion Borsäure verwendet werden. Zur Reinigung kann man das
erhaltene Produkt in Wasser aufschlämmen, welches geringe Mengen eines Alkali enthält. Für dieses Herstellungsverfahren
wird jedoch im Rahmen der Erfindung kein Schutz beansprucht.
Geeignete Vertreter dieser Verbindungsklasse sind beispielsweise:
l-N-Stearoyl-l^-diamino-^lO-dihydroxyanthrazen
l-N-Dodecoyl-M-diamino-^lO-dihydroxyanthrazen
l-N-Octoyl-l,4-diamino-9,10-dihydroxyanthrazen
l-N-Propoyl-l^diamino^.lO-dinydroxyanthrazen
1 -N- Heptoyl-1,2-diamino-9,1O-dihydroxyanthrazen
l-N-Stearoyl-l,2-diamino-9,10-dihydroxyanthrazen
l-N-Decoyl-l,2-diamino-9,10-dihydroxyanthrazen
Die entsprechenden 1,4-Diaminoanthrachinone können ebenfalls verwendet werden.
N-Acylaminophenole, welche sich zur Herstellung
der nichtseifenhaltigen Schmierfette gemäß der vorliegenden Erfindung eignen, haben die folgende allgemeine
Formel:
R'
HO!
H ii
N —C —R
R"
In dieser Formel bedeutet R eine Alkylgruppe mit 14 bis 22 Kohlenstoffatomen, welche vorzugsweise
keine benzolartige Struktur aufweist, und R' sowie R" stellen Wasserstoffatome oder Alkylgruppen mit 1 bis
20 Kohlenstoffatomen dar.
Gemäß einer bevorzugten Ausführungsform der Erfindung werden Verbindungen mit der oben angegebenen
Strukturformel verwendet, wobei R' und R" WasserstofFatome sind und R eine geradkettige aliphatische
Gruppe mit 14 bis 22 Kohlenstoffatomen ist. Vertreter dieser bevorzugten Verbindungsklasse sind
beispielsweise N-Palmitoyl-p-aminophenol, N-Stearoyl-p-aminophenol
und N-Arachidoyl-p-aminophenol sowie N-Behenoyl-p-aminophenol.
Alkylierte Acyl-p-aminophenole, welche gleichfalls
durch die oben angegebene Strukturformel charakterisiert werden, wenn R' und R" in derselben Alkylgruppe
mit 1 bis 20 und vorzugsweise zwischen 4 und 15 Koho lenstoffatomen darstellen, sind gleichfalls als Verdickungsmittel
für ein Schmieröl brauchbar, wie z. B. N-n-Valeryl-4-amino-3-pentadecylphenol, N-n-Pentanoyl-4-amino-3-pentadecylphenol,
N-n-Propanoyl-4-amino-2,6-ditert. butylphenol, N-n-Hexyl-4-amino-2-hexylphenol.
Die Art des zur Herstellung der erfindungsgemäßen Schmierfette verwendeten Schmieröls kann sehr stark
variieren. Das ausgewählte Öl sollte die erforderlichen Schmierfunktionen auch dann ausüben können, wenn
man es als Flüssigkeit anwenden würde. Für die meisten Anwendungszwecke können Mineralschmieröle mit
einer Viskosität im Bereich zwischen etwa 35 und 200 SUS bei 98,9 0C eingesetzt werden. Es kann sich
dabei je nach der Herkunft des Rohöls um ein Mineralöl von paraffinischem oder naphthenischem Charakter
handeln. Auch die verschiedenen, mittels der mannigfachen Raffinationsverfahren zugänglichen Destillate
sind für diesen Zweck gut brauchbar.
Synthetische Schmieröle können gleichfalls zur Herstellung der erfindungsgemäßen Schmierfette verwendet
werden. Zu derartigen Ölen gehören beispielsweise die Ester von einbasischen Säuren, wie der Ester des
C8-Alkohols aus der Oxosynthese und einer Säure mit 8 Kohlenstoffatomen aus der Oxosynthese, ferner
Ester von zweibasischen Säuren, wie Di-2-äthylhexylsebacat
und Dinonyladipat. Auch Ester von Glykolen, beispielsweise der C13-Oxosäure-Diester von Tetraäthylenglykol
und komplexe Ester sind gut brauchbar, wie der sich bei der Umsetzung von 1 Mol Sebacinsäure
mit 2 Mol Tetraäthylenglykol und 2 Mol2-Äthylcapronsäure bildende Komplex. Auch eine erst neuerdings
entwickelte Verbindungsklasse, nämlich Diaryldialkylsilane, beispielsweise Diphenyldidodecylsilan,
können als Schmierölbasis verwendet werden. Desgleichen sind Ester der Phosphorsäure geeignet, beispielsweise
der sich aus 3 Mol Monomethyläther von Äthylenglykol und 1 Mol Phosphoroxychlorid bildende
Ester. Aus halogenhaltigen Kohlenwasserstoffen bestehende öle, wie polymeres Chlortrifluoräthylen,
können in gleicher Weise eingesetzt werden wie Alkylsiliconverbindungen,
z. B. Methylpolysiloxane und Chlorphenolsilikone. Geeignete Schwefelsäureester bilden
sich bei der Umsetzung von 1 MqI Schwefeloxychlorid mit 2 Mol Methyläther des Äthylenglykols.
Auch gewisse Carbonate sind für diesen Zweck verwendungsfähig, wie sie beispielsweise bei der Reaktion
eines C8-Oxoalkohols mit Äthylcarbonat und anschließende
Umsetzung des gebildeten Halbesters mit Tetraäthylenglykol entstehen. Ferner können Mercaptane
als Schmierölbasis verwendet werden. Formale sind gleichfalls geeignet, beispielsweise die durch Umsetzung
eines C13-Osoalkohols mit Formaldehyd entstehende
Verbindung. Weiterhin lassen sich PoIyglykole verwenden, wie die durch Kondensation von
Butylalkohol mit bis zu 50 Einheiten Propylenoxyd entstehenden Produkte. Auch Mischungen der genannten
synthetischen Öle in beliebigen Anteilen lassen sich verwenden.
Es ist bereits vorgeschlagen worden, auf dem Gebiet der Schmierung unter Einwirkung ionisierender Strahlung
Polyphenyläther als Schmiermittel oder Schmiermittelkomponente zu verwenden. Die maximale Stabilität
wird erzielt, wenn die betreffenden Polyphenyläther keine Substituenten aufweisen, doch werden auch
dann noch sehr stabile Schmiermittel erhalten, wenn die betreffenden Äther Alpha-Cumyl- oder Tertiärbutyl-Substituenten
enthalten. Obwohl die Phenylreste untereinander durch Ortho-, Meta- oder Parabindungen
verknüpft sein können, wird es doch vorgezogen, daß wenigstens 25% der Ätherbindungen sich zueinander
in Metastellung befinden, Vorzugsweise soll der betreffende Polyphenyläther im Durchschnitt drei bis
sechs Phenylreste pro Molekül enthalten. Es hat sich gezeigt, daß eine Kombination der aufgeführten Typen
von Verdickungsmitteln mit derartigen Schmierölen zu Schmierfetten führen, die sowohl bei Temperaturen
5 oberhalb 1770C als auch unter der Einwirkung ionisierender
Strahlung außerordentlich stabil sind.
Die folgenden Beispiele erläutern die unerwartete Verbesserung hinsichtlich der Konsistenz eines mit
N-Dihydro-l^-l'^'-anthrachinonazinalsVerdickungs-
o mittel hergestellten Schmierfettes, wobei 28 Gewichtsprozent
des gesamten Fettes aus dem Verdicker bestehen, während der restliche Anteil ein Rückstandsschmieröl auf Mineralölbasis, d. h. ein Brightstocköl
ist.
