Description
- Die vorliegende Erfindung betrifft Schmiermittel- oder Hydraulikölzusammensetzungen enthaltend als Additive eine Mischung aus einem öllöslichen, gegebenenfalls benzokondensierten 5-Ring-Heterocyclus mit einer tautomeren 2-Mercapto-1,3-heteroatom-aza-Gruppe und einer Phosphorverbindung, sowie die Verwendung dieser Mischungen als Additive in Schmiermitteln oder Hydraulikölen.
- Mineralischen und synthetischen Schmiermitteln werden üblicherweise Additive zur Verbesserung der Gebrauchseigenschaften zugesetzt. Zur Verbesserung der Verschleissschutzeigenschaften werden den Schmiermitteln Hochdruck- und verschleissmindernde Additive zugefügt. An diese wird die Anforderung gestellt, dass sie nicht korrodierend auf die zu schmierenden Metallteile wirken und eine gute Hitzebeständigkeit aufweisen.
- Weltweit werden verschiedene Typen zon Zinkdialkyldithiophosphaten (ZDTP) als Verschleissschutzadditive eingesetzt.
- Die Verwendung gegebenenfalls benzokondensierter 5-Ring-Heterocyclen mit einer tautomeren 2-Mercapto-1,3-heteroatom-aza-Gruppe und gegebenenfalls weiteren Stickstoffatomen im Ringsystem als Schmiermittelzusätze ist bekannt. Diese zeigen jedoch im allgemeinen, besonders bei höheren Temperaturen, nur ungenügende Verschleissschutzeigenschaften.
- So werden in der DE-A 2,605,655 Aminobenzthiazoldisulfide, wie z.B. Morpholinobenzthiazoldisulfid, in Kombination mit ZDTP als Schmieröl- bzw. Kraftstoff-Additive beschrieben.
- In der US-A 3,966,623 wier die synergistische Mischung aus Mercaptobenzthiazol-Amin-Salzen mit 2,5-Dimercapto-1,3,4-thiadiazoldisulfiden als Korrosionsinhibitoren in Schmierölen beschrieben.
- Ferner beschreibt die EP-A 150,957 die Verwendung von Mercaptobenzthiazol-Amin-Salz-Lösungen in überschüssigem Amin zur Verbesserung der antioxidativen und antikorrosiven Eigenschaften von Kraftübertragungsflüssigkeiten. Weiter sind aus der US-A 3,779,919 Rhodamin-Amin-Salz als Zusätze zur Verbesserung des Lasttragevermögens von synthetischen Turbinenölen bekannt.
- Es wurde nun gefunden, dass Mischungen aus öllöslichen 5-Ring-Heterocyclen, die eine tautomere 2-Mercapto-1,3-heteroatom-aza-Gruppe aufweisen und gegebenenfalls benzokondensiert sind, bzw. deren Aminsalzen mit verschiedenen Derivaten von Phosphorsäure-, Thio-, Dithio- oder Trithiophosphorsäureestern sowie von Phosphorigsäureestern besonders gute verschleissmindernde Eigenschaften, insbesondere bei höherer Temperatur, aufweisen bei gleichzeitig herabgesetztem P-Gehalt der Mischungen.

Die Herstellung der Phosphor-Verbindungen ist beispielsweise in Houben-Weyl "Methoden der organischen Chemie", Band 12, Teil 2, 4. Auflage, G. Thieme Verlag, Stuttgart 1964, auf den Seiten 53-77, 143-210, 226-274, 299-376 sowie 587-748 beschrieben. Ihre Aminsalze werden analog zu denen der heterocyclischen Verbindungen hergestellt.

- Die Gemische können als solche dem Schmiermittel zugefügt werden, oder es können die Komponenten wie z.B. 2-Mercaptobenzthiazol-Amin-Salze und die Phosphorverbindung getrennt hergestellt und dem Schmiermittel bei der Formulierung getrennt zugesetzt werden. Bei hochviskosen Gemischen bietet die Verdünnung mit z.B. einem entsprechenden Grundöl eine günstige Konfektionsform.
- Die in Frage kommenden Schmiermittel bzw. Hydrauliköle sind dem Fachmann geläufig und z.B. im "Schmiermittel Taschenbuch" (Hüthig Verlag, Heidelberg, 1974) resp. in "Ullmanns Encyclopädie der technischen Chemie" Bd. 13, Seiten 85-94 (Verlag Chemie, Weinheim, 1977) beschrieben.
- Besonders geeignet sind neben Mineralölen z.B. Poly-α-olefine, Schmiermittel auf Esterbasis, Phosphatester, Glykole, Polyglykole und Polyalkylenglykole.
- Die Schmiermittel können zusätzlich andere Additive enthalten, die zugegeben werden, um die Grundeigenschaften von Schmierstoffen und Hydraulikölen noch weiter zu verbessern; dazu gehören Antioxidantien, Metallpassivatoren, Rostinhibitoren, Viskositätsindex-Verbesserer, Stockpunkterniedriger, Dispergiermittel, Detergentien, Hochdruck-Zusätze sowie andere Verschleissschutz-Additive.

- Die Verschleissschutzwirkung wird mit einem kommerziellen Schwing-Reib-Verschleissgerät (SRV-Gerät) der Firma Optimol GmbH, München bestimmt. (R. Schumacher et al. ASLE Transaction 26, 1(1983), 94-101).
- Dieses Gerät basiert auf dem folgenden Prinzip: Eine Stahlkugel (100 Cr 6), auf die eine Kraft FN wirkt, oszilliert auf einem Stahlzylinder. Die Kugel ist in einer Halterung fixiert und führt demnach eine oszillierende Gleitbewegung aus. Die Horizontal- und Vertikalkraft wird durch einen piezoelektrischen Kraftaufnehmer bestimmt. Unter den vorliegenden Versuchsbedingungen beträgt die maximale Herz'sche Normalspannung 2740 N/mm², die maximale Schubspannung 850 N/mm². Kugel und Zylinder sind aus demselben Werkzeugstahl hergestellt worden.
- Einige Tropfen Oel, welche die zu untersuchende Verbindung gelöst enthält, werden zwischen Zylinder und Kugel aufgebracht. Die folgenden Testbedingungen werden gewählt:
Last: 200 N, Frequenz: 50 Hz, Amplitude: 1000 µ,
Temperature: 130°C-150°C, Prüfzeit: 2 h.
Prüföl: Polyalphaolefin ISO VG 100, S-Gehalt <1,5 ppm. - Zur Charakterisierung des Verschleisses wird mit einem Tastschnittgerät (Talysurf der Firma Rank Taylor Hobson, Leicester, England) ein Querprofil aufgenommen. Als Verschleissmass dient die integrierte Querprofilfläche. Bei den angegebenen Werten handelt es sich um ein relatives Verschleissmass. Der wahre Verschleisswert berechnet sich durch Multiplikation mit dem Faktor F = 2 x 10⁻⁴.
-
- Durchführung analog zu Beispiel 26.
Prüftemperaturen 130°C-150°C. - Prüföl I : Paraffinbasisches Grundöl ISO VG 32 mit handelsüblichen Zusätzen
0,75 % Zinkdialkyldithiophosphat (ZDTP)
11 % Detergens
6 % Viskositätsindexverbesserer -
