Abstract
Schmierstoffe können gegen Oxidation stabilisiert werden durch Zusatz von a) einem sterisch gehinderten Amin und b) einem Phenol der Formel I, worin A, B und X die in Anspruch 1 gegebenen Bedeutungen haben. Vorzugsweise verwendet man Phenole der Formel I, die eine Thioethergruppe enthalten. Formel I{Schmierstoffzusammensetzung; Stabilisierung gegen Oxidation; sterisch gehindertes Amin; Phenol; Phenol mit Thioethergruppe}
Description
Die vorliegende Erfindung betrifft Schmierstoffzusammensetzungen, die gegen oxidativen Abbau stabilisiert sind. Die Stabilisierung erfolgt durch Zusatz von mindestens zwei spezifischen Zusatzstoffen.
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 (siehez. B. Ulimanns Encyklopädie der technischen Chemie, 4.Auflage, Verlag Chemie, Band 20 [1981]; Seite 541-53).
Es wurden auch schon sterisch gehinderte Amine als Stabilisatoren für Schmieröle vorgeschlagen, z. B. in der US-A-4 069199 oder der JP-A-85/28496.
In der EP-A-356677 wurden Gemische von aromatischen Aminen und sterisch gehinderten Aminen als Antioxidantien für Schmierstoffe vorgeschlagen, wobei diesen Gemischen auch phenolische Antioxidantien zugesetzt werden können.
Es wurde gefunden, daß sich Kombinationen von phenolischen Antioxidantien mit sterisch gehinderten Aminen auch ohne Zusatz von aromatischen Aminen hervorragend zur Stabilisierung von Schmierstoffen eignen.
Die vorliegende Erfindung betrifft eine Schmierstoffzusammensetzung, enthaltend
(A) ein mineralisches oder synthetisches OeI oder ein Gemisch solcher OeIe,
(B) mindestens ein sterisch gehindertes Amin und
(C) mindestens ein Phenol der Formel I,

Die Oxidationsbeständigkeit der erfindungsgemäß stabilisierten Öle wird in einem Differential-Scanning-Kalorimeter gemessen.
Dabei wird in einem Al-Schälchen ein Basisöl mit 0,025% Eisen-lll-acetylacetonat (als Oxidationskatalysator) und 0,55% eines Stabilisato· s vermischt und im Kalorimeter unter 10bar Sauerstoff isotherm auf 160 JC erwärmt. Gemessen wird die Zeit bis zum Beginn der exothermen Reaktion Tb (Induktionszeit) und die Zeit bis zum Ende der exothermen Reaktion TE. Je langer die Induktionszeit ist, desto höher ist die Oxidationsbeständigkeit.·Als Stabilisatoren werden die phenolischen Antioxidantien P-1 und P-2 verwendet sowie:

Daran ist zu ersehen, daß bei Verwendung von Stabilisaxorgemischen aus 0,10% der Komponente A und 0,45% der Komponente B die Oxidationsbeständigkeit 'es Öles höher ist, als aus den Daten der einzelnen Komponenten zu erwarten wäre
Die Oxidationsbeständigkeit wird wie in Beispiel 6 in einem Differential-Scanning-Kalorimeter getestet, mit dem Unterschied, daß statt unter Sauerstoff unter 8bar Luft, der 380ppm (NO)x beigemischt sind, gemessen wird und daß die isotherme Temperatur 170°C beträgt.
