Description
DEUTSCHES
Die Erfindung bezieht sich auf Schmieröle, die insbesondere zur Verwendung bei Verbrennungskraftmaschinen
zum Schutz des Motors gegen Rosten und andere Formen der Korrosion während des Stilliegens
geeignet sind.
Zur Lösung dieses Problems hat man bereits Antirostmittelmischungen
empfohlen, die aus Diestern von gewissen Dicarbonsäuren, z. B. Dibutyladipinsäureester,
und solchen organischen Säuren bestehen, welche in Wasser unlösliche Metallseifen bilden. Hierbei können
zur Erhöhung der Rostschutzwirkung gegebenenfalls auch noch kleine Mengen von Teilestern mehrwertiger
Alkohole zugesetzt werden.
Auch ist die Kombination eines Sorbitanmonoesters einer aliphatischen Monocarbonsäure mit 16 bis 18
Kohlenstoffatomen im Molekül und eines Glykolteilesters einer Fettsäure als Mittel zur Verhütung der
korrodierenden Einwirkung von Schmierölen in feuchter Luft und bei Anwesenheit von Salzwasser auf Metallteile
beschrieben.
Ferner ist die verschleißvermindernde Wirkung eines Zusatzes von weniger als 1 % eines öllöslichen aliphatischen
Teilesters eines mehrwertigen Alkoholes und von 1 bis 5°/0 eines Erdalkalisalzes von einem Alkylphenolsulfid
oder einem sulfurierten Alkylphenol zu einem Schmieröl für Kraftfahrzeuge bekannt.
Es wurde nun gefunden, daß die an sich noch nicht befriedigenden rostschützenden Eigenschaften von Teilestern
mehrwertiger Alkohole und insbesondere der 4- bis 6-wertigen Alkohole in Schmierölen ganz entscheidend
verbessert werden können, wenn man denselben gleichzeitig eine kleinere Menge eines öllöslichen
Salzes einer aromatischen Carbonsäure einverleibt.
Es ist zwar schon vorgeschlagen worden, Teilester mehrwertiger Alkohole in rostverhindernden Mischungen
zu verwenden, manchmal sogar in Verbindung mit verschiedenen Metallsalzen. Es wurde jedoch überraschenderweise
festgestellt, daß die einfachen Teilester, wie Glycerinmonoölsäureester und Glycerinmonostearinsäureester
keinen ausreichenden Schutz gegen eine Motorkorrosion ergeben. Dagegen bewähren sich die
erfindungsgemäß eingesetzten Teilester der höheren, mehrwertigen Alkohole, nämlich solcher mit 4, 5 oder
6 Hydroxylgruppen im Molekül in dieser Hinsicht ganz ausgezeichnet. So entspricht eine in den Beispielen beschriebene
und mit A bezeichnete Mischung allen Anforderungen bei der Untersuchung nach der Prüfmethode
»Ministry of Supply DEF/2181 specification for aircraft
engine preservative oils«, einschließlich der Prüfung der Korrosion gegenüber nicht Eisenmetallen, während
eine ähnliche Mischung, welche aber Glycerinmonoölsäureester an Stelle des Sorbitmonoölsäureesters enthält,
bei dem gleichen Korrosionstest sowohl in bezug auf Aluminium als auch auf Kupfer versagt.

Die erfindungsgemäß eingesetzten Metallsalze einer aromatischen Carbonsäure sind gleichfalls an sich als
Schmiermittelzusatz bekannt, doch üben sie selbst keinerlei rostvermindernde Wirkung aus. Es ist daher
als besonders überraschend anzusehen, daß diese Stoffe die Antircstwirkurg der Teilester günstig beeinflussen.
Die Ölbasis, welche den Hauptbestandteil des Schmieröls gemäß vorliegender Erfindung darstellt, kann entweder
ein synthetisches oder ein mineralisches Schmieröl sein. Die Viskositätseigenschaften geeigneter öle können
zwischen denjenigen von SAE-5W-Ölen und SAE-
60-Ölen schwanken, Öle mit hohen Viskositäten, wie SAE-40-, -50- und -60-öle, werden aber bevorzugt. Die
Mineralschmieröle können aus allen Arten von rohen Erdölen, wie naphthenischen, paraffinischen oder asphaltischen
Rohölen herstammen, wobei sie im allgemeinen eine oder mehrere der üblichen Raffinationsbehandlungen
durchgemacht haben. Gemische aus mineralischen ölen und fetten Ölen, wie Rizinusöl und Specköl, können
ebenso verwendet werden wie synthetische Schmieröle und Gemische derselben mit mineralischen und bzw.
oder fetten Ölen. Geeignete synthetische Schmieröle können durch Polymerisieren von Olefinen oder durch
Alkylieren von aromatischen Kohlenwasserstoffen mit Olefinen oder mit Alkylhälogeniden in Anwesenheit
eines Friedel-Crafts-Katalysators hergestellt werden.
Auch organische Ester, z. B. Dialkylester von Dicarbonsäuren, wie Sebacinsäure- oder Adipinsäure-di-(2-äthylhexyl)-ester,
sowie die Alkyl- oder Alkarylester anorganischer Säuren, z. B. Trioctyl- oder Trikresylphosphat
und Tetraoctylsilicat und Polymere oder Mischpolymere

1. Schmieröl auf der Basis eines mineralischen oder synthetischen Schmieröles mit einem Gehalt an
Teilestern mehrwertiger Alkohole und Metallsalzen organischer Säuren, gekennzeichnet durch einen
geringen Gehalt an einem als Schmiermittelbestandteil an sich bekannten Teilester eines vier- bis sechswertigen
Alkoholes und einem als Schmiermittelbestandteil an sich bekannten öllöslichen Metallsalz
einer aromatischen Carbonsäure.
2. Schmieröl nach Anspruch 1, dadurch gekennzeichnet, daß es 80 bis 97,5 Gewichtsprozent und
insbesondere von 85 bis 95 Gewichtsprozent eines mineralischen oder synthetischen Schmieröls enthält.
3. Schmieröl nach Anspruch 1 und 2, dadurch gekennzeichnet, daß das öllösliche Salz von einer
alkylierten Salicylsäure oder einem Gemisch alkalierter Salicylsäuren abgeleitet ist, wobei die Alkylgruppen
8 bis 18 Kohlenstoffatome enthalten.
4. Schmieröl nach Anspruch 1 bis 3, dadurch gekennzeichnet, daß das öllösliche Salz von einem mehrwertigen

Salz handeln kann.
5. Schmieröl nach Anspruch 1 bis 4, dadurch gekennzeichnet, daß es das öllösliche Salz in einer
Menge von 0,1 bis 2 Gewichtsprozent, berechnet auf das Gesamtgemisch, enthält.
6. Schmieröl nach Anspruch 1 bis 5, dadurch gekennzeichnet, daß sich der Teilester von Sorbit,

Kohlenstoffatomen im Molekül ableitet, wie Sorbitoder Sorbitanmonoölsäureester.
7. Schmieröl nach Anspruch 1 bis 6, dadurch gekennzeichnet, daß es den Teilester in einer Menge von
0,5 bis 10 Gewichtsprozent, vorzugsweise von 2 bis 70I0, berechnet auf das Gesamtgemisch, enthält.
8. Schmieröl nach Anspruch 1 bis 7, gekennzeichnet durch einen weiteren Gehalt an einem als Schmiermittelbestandteil
an sich bekannten öllöslichen Metallsalz, vorzugsweise einem Alkalisalz, einer organischen
Sulfonsäure, wie Erdölsulfonsäure.
9. Schmieröl nach Anspruch 8, dadurch gekennzeichnet, daß es das öllösliche Metallsalz einer organischen
Sulfonsäure in einer Menge von 1,25 bis 7,5 Gewichtsprozent, berechnet auf das Gesamtgemisch,
