Schmiermittelgemische.
Die vorliegende Erfindung betrifft Schmiermittel gemische,.die eine einzigartige Grundflüssigkeit für Schmiermittel und ein Antioxydationsmittel enthalten. Diese Schmiermittelgemische haben annehmbare Flammpunkte, Frostpunkte und Belastungseigenschaften, so daß sie als Schmiermittel für Düsenmaschinen verwendet werden können.
Dipropylenglycoldipelargonat wurde als Grundflüssigkeit für synthetische Schmiermittelgemische verkauft. Dieses Material besitzt einen Flammpunkt, der zu niedrig ist, um beispielsweise bei Schmiermittelgemischen für Düsenmaschinen verwendet zu werden, da bei hohen Temperaturen ein zu großer Teil der Flüssigkeit durch Verdampfen verloren gehen würde. Da Dipropylenglycoldipelargonat ferner einen sehr niedrigen Gießpunkt hat, erstarrt es, wenn es bei Temperaturen gehalten wird, bei denen es flüssig blei-
109830/1677
ben soll.
Die vorliegende Erfindung betrifft Schmiermittel gemische, die Fettsäurediester von Tripropylenglycol, bei denen jeder Fettsäureanteil etwa 6 bis 10 Kohlenstoffatome, ■ vorzugsweise von 7 bis 9 Kohl ens to ff atome enthält, und
0,001 bis etwa 5# eines Antioxydationsmittels, das ein Gemisch von ρ,ρ'-Dioctyldiphenylamin und N-Phenyl-1,2,3»4— tetrahydro-2-naphthylamin ist, enthalten.
Die einzigartige Grundflüssigkeit für Schmiermittel .'. dieses Gemisches ist ein Fettsäurediester von Tripro -
^ pylenglycol. Fettsäurediester von Dipropylenglycol haben
^ Flammpunkte, die zu niedrig sind, um als Schmiermittel für
die neusten Düsenmaschinen verwendet zu werden, und Dipropylenglycol- und Tetrapropylenglycoldiester werden fest, wenn sie bei niedrigen Temperaturen, z.B. etwa -54°C gehalten werden. Außerdem werden Diester von Tripropylenglycol, die;zwei Fettsäurereste mit etwa 6 Kohlenstoffatomen oder weniger enthalten, unter extremen Temperaturbedingungen zersetzt, und Ester, die Fettsäuren mit 10 oder mehr Kohlenstoffatomen enthalten, neigen zu zu hohen Gießpunkten. Zur Verwendung als Schmiermittel für Düsen maschinen ist es daher erforderlich, daß Diester von Tripropylenglycol verwendet werden, bei denen die Fett fe säuren von etwa 6 bis etwa 10 Kohlenstoffatome enthalten,
und bei denen nur kleinere Mengen der Fettsäuren entweder 6 oder 10 Kohlenstoffatome enthalten. Kleine Mengen an C-,-,- und höheren Fettsäuren können in den Diestern vorhanden sein, im allgemeinen sollten sie jedoch vermieden werden. Synthetische Fettsäuren können gleichfalls verwendet werden.
Geeignete Tripropylenglycoldiester werden in den nachfolgenden Beispielen beschrieben. Andere Grund -
10 9 8 30/1677
flüssigkeiten für Schmiermittel können gleichfalls zu sammen mit den erfindungsgemäßen, spezifischen, einzigartigen Grundflüssigkeiten für Schmiermittel verwendet „ werden.. Geeignete-Grundflüssigkeiten werden in der Deutschen :Patentanmeldung P 1948436 "beschrieben. Diese Anmeldung dient als Bezugsgrundlage für die vorliegende Anmeldung. . . ...... : ,
Der Tripropylenglycoldiester, der als Grundmaterial für das erfindungsgemäße Schmiermittel dient, scheint aufgxmnd des Wasserst off atoms, das an ein tertiäres Kohlenstoffatom der Tripropylenglycolkette gebunden ist, zu unbeständig zu sein, um bei den hohen Tem- .:, . J peraturen der neusten Düsenmaschinen allein verwendet zu werden. Um daher den Tripropyl englycoi diester, in einem. Schmiermittel für eine Düsenmaschine zu verwenden, muß . man ein -wirksames Antioxidationsmittel einarbeiten.
Antioxidantien sind,gut "bekannte Schmiermittel - ■ , zusätze. Das "bevorzugte Antioxidationsmittel ist ein ;· =
Gemisch von p'jp'-Dioctyldiphehylamin und·li-Phenyl-l,2,3,4-
tetrahydro-2-naphthylamin.. Das li-Phenyl-ljg.^jA-teträ - ^
hydro-2-naphthylamin soll etwa 30 bis BO a/o>. des Gemisches, vorzugsweise et(wa 50' bis 70. fy, ausmachen. Vorzugsweise . sollen diese beiden Amine in einem Verhältnis, von zwei ■■ ■ Teilen p.p'.-Dioctyldiphenylamin zu drei Teilen N-Phenyl- i
1,2,3t4-tetrahydro-2-naphthylamin verwendet werden. Eine, bevorzugteHKonz^entratipn. des Antioxidatio^nsmi.t^e^qi^l.iegt ,», .-.-.-bei etwa.A:,;5 Gew.-^..,bezogen auf das Schmiermitteige r- ■ misch, und ,ein bevorzugter B,erei,ch liegt bei etwa 0,1: bis.·
Es wird angenommen, daß das ρ,ρ'-Dioetyldiphenyl-(1) als Inhibitor tür-Freie Radikale,, (2) ,als; dispergie-

rendes Mittel und (3) sekundär als Base wirkt. Es wird angenommen, daß das N-Phenyl-1,2,3 ^-tetrahydro-2-naphthylamin primär als Base wirkt, um eventuell bei der Lagerung oder Verwendung erzeugte Säure zu neutralisieren. Andere Materialien, die den gleichen Funktionen dienen, können entweder vollständig oder teilweise an stelle der vorstehend genannten Komponenten des Anti oxidationsgemischs ersetzt werden.
Zu den weiteren Zusätzen, die den erfindungsgemäßen Schmiermittelgemischen zugesetzt werden können, gehö-". ren Mittel zur Verbesserung des Viskositätsindex, Mittel " zur Herabsetzung des Gießpunktes, dispergierende Mittel, Mittel zur Verhinderung der Abnutzung (anti-wear additives), Metalldesaktivatoren usw..
Hie Mittel zur Verbesserung des Viskositätsindex werden normalerweise in einer Konzentration von etwa 0,01 bis 2 Gew.-^j bezogen auf das Schmiermittelgemisch, verwendet. Geeignete Mittel sind z.B. Polyisobutene, Polymethacrylate, Vinylacetat-Fumarsäureester-Mischpolymere und Polyacrylate.
Die Mittel zur Herabsetzung des Gießpunktes wer-■* den in einer Konzentration von etwa 0,01 bis 2 Gew.-#,
bezogen auf das Schmiermittelgemisch, verwendet. Geeigfe nete Mittel zur Herabsetzung des Gießpunktes sind die vorstehend angeführten Mittel zur Verbesserung des Viskositätsindex, alk.ylierte Wachse, Naphthaline, Poly methacrylate sowie alkylierte Wachsphenole.
Die Metalldesaktivatoren (Antikorrosionszusätze) werden normalerweise in einer Konzentration von etwa 0,001 bis 0,5 Gew.-^, bezogen auf das Schmiermittel-

gemisch, verwendet. Geeignete Metalldesaktivatoren sind z.B. Disalicyliden-l^-diaminpropan, Benzoguanamin und N-Alkyl- sowie Mngalkyl-substituierte Benzoguanamine, Thioharnstoffe, Octadecylamin, Chinizarin, Chinoline, .Phenylaeridin, Hexamethylentetramin, Thiobenzamid, Benzothiadol und Imidazoline
Die Mittel zur Verhinderung der Abnutzung werden normalerweise in einer Konzentration von etwa 0,01 bis 5 Gew.-^, bezogen auf das Schmiermittelgemisch, verwendet. Geeignete Zusätze zur Verhinderung der Abnutzung sind Tricresylphosphat, organische Phosphite und langkettige Methylendiphosphonatester. ' -
Dispergierende Mittel werden normalerweise in einer
Konzentration von etwa 0,01 bis 2 Gew.-^, bezogen auf das Schmiermittelgemisch, verwendet. Geeignete dispergierende Mittel sind die vorstehend angegebenen Mittel zur Verbesserung des Viskositätsindex, Mischpolymere von Methacrylate?! oder Acrylaten, N-substituierte lang kettige Alkenylsuccinimide, hochmolekulare Ester oder Polyester und Vinylacetat-Fumarsäureester-Mischpolymere.
Andere geeignete Zusätze werden in der Kanadischen Patentschrift 792 739 beschrieben, das als Bezügsgrundlage für die vorliegende Anmeldung dient.

Die essentiellen Fettsäurediester von Tripropylen-. glycol können mit anderen bekannten Grundflüssigkeiten für Schmiermittel kombiniert werden, um ihre Eigenschaften zu verbessern. Im weiteren Sinne kann die andere Grundflüssigkeit entweder ein Petroleumkohlenwasserstoff, ein Fettsäuretriglycerid, eine synthetische Flüssigkeit (fluid), eine wässrige Grundflüssigkeit (based) oder Gemische derselben sein. Petroleumkohlenwasserstoffe um - · , /fassen Mineralöl (z.B. leichte Lösungsmittel, neutrale Öle,
■■'-■; 109830/ 1677 -
schwere, klare und raffinierte Fraktionen sowie asphalthaltige Rückstände), Fette und Wachse. Die Grundflüssigkeiten der Schmiermittel können auch Suspensionen von Graphit in Ölen umfassen. Synthetische Flüssigkeiten sind beispielsweise disparate Materialien, wie polymerisierte Olefine, organische Carbonate, organische Ester und/oder Äther, Polyglycole, Silicone, modifizierte organische Stoffe (halogenierte, phosphatierte, sulfurier te Stoffe usw.),. Polymere, z.B. Alkylmethacrylatpolymere und synthetische Harze, z.B. Harze, die durch Veresterung von mehrwertigen Alkoholen mit Polycarbonsäuren erhalten wurden. Beispiele für Grundmaterialien, die bei der Durchführung der vorliegenden Erfindung verwendet werden können, werden in den USA-Patentschriften 2 599 761, 2 725 359, 2 767 142, 2 882 228, 2 956 952, 2 993 859, 3 296 sowie 3 357 920 beschrieben. Weitere geeignete Schmier mittelgrundmaterialien werden in der "Encyclopedia of Chemical Technology", Kirk-Othmer, 2. Ausgabe, Band 12, Seiten 557-616, insbesondere Seiten 576-582, herausge geben von Interscience Publishers, 1967, genannt. Weitere Beispiele für Grundmaterialien -von Schmiermitteln für die Metallbearbeitung werden in "Metal Working Lubricants" von E.L.H. Bastian, 1. Ausgabe, McGraw-Hill Book Co., Inc., 1951, aufgeführt. Alle vorstehenden Patente und Veröffentlichungen, einschließlich der angeführten Literatur stellen, dienen als Bezugsgrundlage für die vorliegende Erfindung.
Besonders bevorzugt werden bei sole hon Gemischen (1.) andere Ester von Polyolen und einbasischen Säuren, ■ wie Cg-C1p-Fettsäurepolyester von Ä'thylenglycul, Poly äthylenglycol, Propylenglycol, anderen Polypropylen^ly colen, Neopentylglycol, Trimethyloläthan, Trimethylolpropan und Pentaerythrit, (2.)

Zwei Gruppen von Schmiermittelgrundgemischen sind. von "besonderer Bedeutung. Dazu gehören die Materialien, die den Anforderungen, der Militärvorschriften MIL-L-7808 G.. und MIL-L-23699A entsprechen. Die erste Vorschrift (MIL-L-7808G) fordert einen niedrigen Gießpunkt und gute.Ahnutzungseigenschäfteii., Die Gg-G-vQ-Fettsäurediester von ülripropylenglycol sind überlegene Grundflüssigkeiten für Schmiermittel zur Herstellung von Schmiermittelgemisehen, die diesen "Vorschriften entsprechen, welche einen niedrigen Gießpunkt und gute Abrieb eigens eh aft en verlangen. Jedoon können geringe Mengen, gewöhnlich weniger als 50 % an DJ.'.-Gtern von zweibasischen Säuren, z.B. Dioctyladipat O'jiir Di-(2-äth.vJhexvl)-sebacat, zusammen mit den überlet:oneii Tripropvlenglycbldiestei'n verwendet werden. Die ernaltHn^n üetani erraittelgemische können zwar wirtschaft i: cner-Lei ii, jeaoch 'nind' sie nicht so gut wie Schmier mi itui'k'emir.ohe; die nur die Tripropyleriglycoldiester ent- na '. ten. -..-.■■-■.->■■ -
Die zweite Yorücnrift (M1L-1/-23.6699A) erfordert "eine niedrige Verdampfungsgesch-windigkeit, eine höhere Viskosität und einen höheren Grad an Wärmebeständigkeit als bei dein Triprcipylengiycoldiester selbst erhalten wird. Palis jedoch kleine Mengen, gewöhnlich weniger als etwa 50 $ der Tripropylendiester aolchen Flüssigkeiten wie Trimethylolpropantripelärgonat oder PentaerVthrittetraester,

die beispielsweise in der USA-Patentschrift 3 360 465 beschrieben werden (die als Bezugsgrundlage für die vorliegende Anmeldung dient) zugesetzt werden, kann man den Gießpunkt des Schmiermittelgemisches herabsetzen und seine Abnutzungseigenschaften verbessern, ohne den Verdampfungsgrad zu erhöhen und die Viskosität auf einen nicht mehr annehmbaren Wert herabzusetzen.
Die vorliegenden Gemische sind in einzigartiger Weise zur Verwendung als Schmiermittel bei modernen Düsen maschinen geeignet. Die erfindungsgemäßen Gemische sowie längerkettige Säureester sind auch unter Erzielung ver besserter Ergebnisse als Schmiermittel für Kurbelgehäuse von Automobilen, Transmissionsflüssigkeiten, Tieftemperaturschmierfette, Sehmiermittel für gesinterte Lager, Dampfturbinenschmiermittel, Textilgleitmittel, Metallpolierschmiermittel (insbesondere für Aluminium), Bremsflüssigkeiten, Schmiermittel für die Metallbearbeitung, Schmiermittel für Vakuumpumpen, Schmiermittel für Zwei- und Viertaktmaschinen, wie z.B. Rasenmäher, Schmiermittel für geschlossene Schmiermittelsysteme, hydraulische flüssigkeiten im allgemeinen und Automobil- und Lastwagenturbinenmaschinen (automotive and truck turbine engines.) geeignet.
Die folgenden Beispiele dienen der Erläuterung der Erfindung und sollen den Rahmen derselben nicht begrenzen.
Beispiel. 1:
In diesem und den folgenden Beispielen wurden alle .Gießpunkte nach ASTM D97 bestimmt. Die Korrosions- und Oxidationsbeständigkeitstest waren eine Modifikation des

Wurden die Diester 17, 18 und 19 72 Stunden bei -54 C gehalten, so wurden die Diester 17 und 18 fest, wäh-" rend d(;r Diester 19 eine Viskosität von etwa 9,200 Centipoise zurüekbehielt. Dies zeigt ungewöhnliche Viskositätsstabilität der erfindungsgemäßen Diester bei tiefen Temperaturen im Vergleich zu Dipropylenglycol-und Tetra propylenglycolanalogen* Bei dem Vier-Kugel-Test von Shell (4 0 kg Gewi eit, 54,5 C) erzielte man annehmbare Abnutzungserßcheinungen von 0,57,- 0,54 bzw. 0,51 bei den Diestern 17-iy.

Wie aus den vorstehend aufgeführten Daten ersichtlich ist, haben viele Verbindungen, die den essentiellen Tiapropylenglycoldiestern der vorliegenden Erfindung durchaus ähnlich sind, überraschend höhere Gießpunkte, trotz der Tatsache, daß die erfindungsgemäßen Diester höhere Molekulargewichte haben. Es ist überraschend, daß die erfindungsgemäßen Diester so viele der guten Eigen schäften aufweisen, die für die Grundflüssigkeiten erforderlich sind, welche für .die Herstellung von Schmiermittelgemischen zur Verwendung in den fortschrittlichen Düsenmaschinen geeignet sind.
Es wird darauf hingewiesen, daß die Gießpunkte für Diester von Tripropylenglycol niedriger sind als diejenigen für die entsprechenden Diester von Dipropylenglycol, Tetrapropylenglycol und Polyäthylenglycolen.
