Description
- Die vorliegende Erfindung betrifft Schmierstoffzusammensetzungen, die gegen oxidativen Abbau stabilisiert sind. Die Stabilisierung erfolgt durch Zusatz eines sterisch gehinderten Amins von spezifischer Struktur.
- Es ist bekannt und üblich, zu Schmierstoffen auf Basis von Mineralölen oder synthetischen Oelen Zusatzstoffe zur Verbesserung ihrer Gebrauchseigenschaften zuzusetzen. Von besonderer Bedeutung sind Zusatzstoffe gegen oxidativen Abbau der Schmierstoffe, sogenannte Antioxidantien. Der oxidative Abbau von Schmierstoffen spielt vor allem bei Motorenölen eine grosse Rolle, da im Verbrennungsraum der Motoren hohe Temperaturen herrschen und neben Sauerstoff Stickoxide (NOx) vorhanden sind, welche als Oxidationskatalysatoren wirken.
- Als Antioxidantien für Schmierstoffe werden vor allem organische Schwefel- und Phosphorverbindungen verwendet, aber auch aromatische Amine und Phenole, insbesondere sterisch gehinderte Phenole (siehe z.B. Ullmanns Encyklopädie der technischen Chemie, 4. Auflage, Verlag Chemie, Band 20 (1981); Seite 541-43). Es wurden auch schon sterisch gehinderte Amine zur Stabilisierung von Schmierölen vorgeschlagen, z.B. in der US-A-4 069 199 oder der JP-A-85/28496.
- In der EP-A-356 677 werden Gemische von aromatischen Aminen und sterisch gehinderten Aminen als Antioxidantien für Schmierstoffe vorgeschlagen, wobei diesen Gemischen auch phenolische Antioxidantien zugesetzt werden können.
- Es wurde jetzt gefunden, dass sich bestimmte sterisch gehinderte Amine auch allein, d.h. in Abwesenheit eines aromatischen Amins oder eines phenolischen Antioxidans zur antioxidativen Stabilisierung von Schmierstoffen besonders eignen.
- Die Erfindung betrifft eine Schmierstoffzusammensetzung, enthaltend
- (A) ein mineralisches oder synthetisches Oel oder ein Gemisch solcher Oele und
- (B) als antioxidativen Stabilisator ein sterisch gehindertes Amin der Formel I,

Der Schmierstoff kann auch ein Fett auf Basis eines Oeles und eines Verdickungsmittels sein. Solche Schmierstoffe sind z.B. in D. Klamann "Schmierstoffe und artverwandte Produkte", Verlag Chemie, Weinheim 1982, beschrieben.
- Die Komponente (B) wird dem Basisöl vorzugsweise in einer Menge von 0,05 bis 5, insbesondere 0,1 bis 2 Gew.-%, bezogen auf das Basisöl, zugesetzt. Der Zusatz kann direkt erfolgen oder man stellt zuerst eine konzentrierte Lösung von (B) im Oel oder in einem anderen Lösungsmittel her und setzt diese Lösung dem Oel zu.
- Der Zusatz von (B) zum Basisöl bewirkt eine Stabilisierung gegen dessen oxidativen Abbau und bewirkt in Motorenölen eine Verminderung der Schlammbildung.
- Die Schmiermittelzusammensetzung kann zusätzlich andere Additive enthalten, wie z.B. Phosphor-III-ester, Metalldesaktivatoren, Rostinhibitoren, Viskositätsindex-Verbesserer, Stockpunktserniedriger, Dispergiermittel, Tenside oder Verschleiss-schutz-Additive.
- Beispiele für Phosphor-III-ester sind:
Triphenylphosphit, Decyl-diphenylphosphit, Phenyl-didecylphosphit, Tris-(nonylphenyl)-phosphit, Trilaurylphosphit, Trioctadecylphosphit, Distearyl-pentaerythritdiphosphit, Tris-(2,4-di-tert.butylphenyl)-phosphit, Diisodecylpentaerythrit-diphosphit, Bis-(2,4-di-tert.butylphenyl)-pentaerythritdiphosphit, Tristearyl-sorbit-triphosphit, Tetrakis-(2,4-di-tert.butylphenyl)-4,4′-biphenylen-diphosphonit, Bis-(2,6-di-tert.butyl-4-methyl-phenyl)-pentaerythrit-diphosphit. - Beispiele für Metall-Desaktivatoren, z.B. für Kupfer, sind:
Triazole, Benztriazole und deren Derivate, Tolutriazole und deren Derivate, 2-Mercaptobenzthiazol, 2-Mercaptobenztriazol, 2,5-Dimercaptobenztriazol, 2,5-Dimercaptobenzthiadiazol, 5,5′-Methylenbisbenztriazol, 4,5,6,7-Tetrahydrobenztriazol, Salicyliden-propylendiamin, Salicylaminoguanidin und dessen Salze. - Beispiele für Rost-Inhibitoren sind:
- a) Organische Säuren, ihre Ester, Metallsalze und Anhydride, z.B.:
N-Oleoyl-sarcosin, Sorbitan-mono-oleat, Blei-naphthenat, Alkenylbernsteinsäureanhydrid, z.B. Dodecenylbernsteinsäure-anhydrid, Alkenylbernsteinsäure-Teilester und -Teilamide, 4-Nonylphenoxyessigsäure. - b) Stickstoffhaltige Verbindungen, z.B.:
- I. Primäre, sekundäre oder tertiäre aliphatische oder cycloaliphatische Amine und Amin-Salze von organischen und anorganischen Säuren, z.B. öllösliche Alkylammoniumcarboxylate.
- II. Heterocyclische Verbindungen, z.B.:
Substituierte Imidazoline und Oxazoline.
- c) Phosphorhaltige Verbindungen, z.B.:
Aminsalze von Phosphorsäurepartialestern oder Phosphonsäurepartialestern, Zinkdialkyldithiophosphate. - d) Schwefelhaltige Verbindungen, z.B.:
Barium-dinonylnaphthalin-sulfonate, Calciumpetroleum-sulfonate. - Beispiele für Viskositätsindex-Verbesserer sind:
Polyacrylate, Polymethacrylate, Vinylpyrrolidon/Methacrylat-Copolymere, Polyvinylpyrrolidone, Polybutene, Olefin-Copolymere, Styrol/Acrylat-Copolymere, Polyether. - Beispiele für Stockpunkterniedriger sind:
Polymethacrylat, alkylierte Naphthalinderivate. - Beispiele für Dispergiermittel/Tenside sind:
Polybutenylbernsteinsäureamide oder -imide, Polybutenylphosphonsäurederivate, basische Magnesium-, Calcium-, und Bariumsulfonate und -phenolate. - Beispiele für Verschleiss-schutz-Additive sind:
Schwefel und/oder Phosphor und/oder Halogen enthaltende Verbindungen, wie geschwefelte pflanzliche Oele, Zinkdialkyldithiophosphate, Tritolyl-phosphat, chlorierte Paraffine, Alkyl- und Aryldi- und tri-sulfide, Triphenylphosphorothionate, Diethanolaminomethyltolyltriazol, Di(2-ethylhexyl)aminomethyltolyltriazol. - Der Schmierstoff kann auch feste Schmierstoffe enthalten, wie z.B Graphit oder Molybdänsulfid.
- Die folgenden Beispiele erläutern die Erfindung näher. Darin bedeuten % Gewichts-%.
- Beispiel 1: Mittels eines Differential-Scanning-Calorimeters (Thermoanalysator 1090 der Fa. Du Pont) wird die Induktionszeit der Oxidation von Oelproben durch Luft, die 400 ppm NO₂ enthält, unter isothermen Bedingungen gemessen. Die Messung geschieht bei 170°C unter einem Druck von 8 bar. Als Basisöl wird ein Standard-Mineralöl (RL 136) verwendet, dem 1 Vol-% 1-Decen zur Steigerung der Sauerstoffempfindlichkeit zugesetzt wird. Zum Oel werden die folgenden Amin-Stabilisatoren zugesetzt.
- A-1
- 2,2,6,6-Tetramethyl-4-(3-methoxypropylamino)-piperidin
- A-2
- N,N′-Bis(2,2,6,6-tetramethylpiperidin-4-yl)-pentamethylendiamin
- A-3
- N,N′-Bis(2,2,6,6-tetramethylpiperidin-4-yl)-hexamethylendiamin
- A-4
- Bis(2,2,6,6-tetramethylpiperidin-4-yl)-amin
- A-4
- 2,2,6,6-Tetramethyl-4-butylaminopiperidin
- In Tabelle 1 sind die Induktionszeiten angegeben. Je höher die Induktionszeit ist, desto höher ist die antioxidative Wirkung des geprüften Stabilisators.
