Abstract
Description
- Die vorliegende Erfindung betrifft mit Hilfe von Chinolinen stabilisierte Schmiermittel.
- Mineralischen und synthetischen Schmierölen, hydraulischen Flüssigkeiten und Schmierfetten werden im allgemeinen verschiedene Zusatzstoffe zur Verbesserung ihrer Gebrauchseigenschaften beigegeben. Insbesondere besteht ein Bedarf an Additiven, welche die Oxidation bzw. Alterung des Schmierstoffs wirksam inhibieren und somit die Lebensdauer des Schmierstoffs beträchtlich erhöhen.
- 1,2-Dihydrochinoline sind z.B. aus der US-PS 3.910.918 bekannt. Gemäss dieser Patentschrift können diese Verbindungen polymerisiert werden, um hochaktive Antioxidantien für polymere Kunststoffe zu erhalten. Aus der JP-OS 55-026.257 ist bekannt, solche polymere Additive in Kombination mit phenolischen Antioxidantien als Schmiermittelzusätze zu verwenden. Diese Verbindungen und Gemische entsprechen jedoch nicht in jeder Hinsicht den hohen Anforderungen, welche an ein Schmiermittel-Additiv gestellt werden. Ausserdem sind in der US-PS 2,030,033 Hydroxysubstituierte Tetrahydrochinoline als Treibstoffzusätze beschrieben.
- Es wurde nun gefunden, dass monomere 1,2,3,4-Tetrahydrochinoline allein und insbesondere in Kombination mit phenolischen Antioxidantien in Schmiermitteln bei befriedigendem Korrosionsverhalten eine ausgezeichnete Antioxidationswirkung entfalten.

- T. 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.
- d) Schwefelhaltige Verbindungen, z.B.:
- Barium-dinonylnaphthalin-sulfonate, Calciumpetroleum-sulfonate.
- Polymethacrylate, Vinylpyrrolidon/Methacrylat-Copolymere, Polybutene, Olefin-Copolymere, Styrol/Acrylat-Copolymere.
- Polymethacrylat, alkylierte Naphthalinderivate.
- Polybutenylbernsteinsäure-imide, Polybutenylphosphonsäurederivate, basische Magnesium-, Calcium-, und Bariumsulfonate und -phenolate.
- Schwefel und/oder Phosphor und/oder Halogen enthaltende Verbindungen, wie geschwefelte pflanzliche Oele, Zinkdialkyldithiophosphate, Tritolyl-phosphat, chlorierte Paraffine, Alkyl- und Aryldisulfide.
- Folgende der oben erwähnten Chinoline wurden gemäss ASTM D 2272 in Mineralöl Vitrea 100 (ODX) Shell (Viskosität 10,6 mm2/s (100°C) gestestet. Der Versuch ist bei einem Druckabfall von 172,4 KPa (25 psi) beendet. Die in der untenstehenden Tabelle angegebenen Resultate bedeuten die Zeit in Minuten bis der angegebene Druckabfall eingetreten ist. Lange Zeiten entsprechen guter Stabilisatorwirksamkeit.
