Description

DEUTSCHES
Die vorliegende Erfindung bezieht sich auf flüssige, nichtbrennbare Schmiermittel auf Molybdän-Disulfid-Basis.
Es ist bekannt, Mineralöle oder andere flüssige Schmierstoffe durch den Zusatz von Molybdän-Disulfid hinsichtlich ihrer. Notlaufeigenschaften zu verbessern.
Es sind auch Aufschlämmungen von Molybdän-Disulfid in wäßrigem Medium bekannt. Diese wäßrigen Aufschlämmungen bezwecken die Erzielung von Trockenfilmschmierschichten. Hierbei dient das Wasser bzw. der Methylalkohol lediglich als Trägersubstanz, um die mit einem Trockenschmierfilm zu versehenden Reibungsflächen überstreichen zu können. Bei diesen Anwendungen kommt es auf eine möglichst rasche Verdunstung der flüssigen Trägersubstanzen an.
Die vorliegende Erfindung hat sich die Aufgabe gestellt, einen nichtbrennbaren, flüssigen Schmierstoff auf der Basis einer wäßrigen Dispersion von Molybdän-Disulfid herzustellen.
Die vorliegende Erfindung besteht darin, daß dem flüssigen, aus einer wäßrigenDispersion von Molybdän-Disulfid bestehenden Schmiermittel wasserlösliche, unter Normalbedingungen feste Stoffe zugesetzt sind, die in wassergelöstem Zustand .die Viskosität erhöhen.
Als solche viskositätserhöhenden Zusätze können insbesondere Sorbit und/oder Polyvinylpyrrolidon und/oder Polyalkylenglykoleund/oder Polymerisationsprodukte der Acrylsäure und/oder Polyvinylalkohole und deren Derivate und/oder Stoffe auf der Basis von Methylcellulose verwendet werden.
Das erfindungsgemäße Schmiermittel weist den Vorteil auf, daß die in Frage stehenden viskositätserhöhenden Zusätze bereits in geringen Mengen eine erhebliche Viskositätssteigerung ermöglichen. Außerdem ergibt sich infolge der Wasserlöslichkeit der Zusätze eine unbegrenzte Stabilität der Lösung. Ein weiterer Vorteil besteht darin, daß keine Emulgatoren benötigt werden. Insgesamt ergibt sich weiterhin aus der Hinzufügung dieser Bestandteile eine erhebliche Steigerung der Stabilität der Molybdän-Disulfid-Dispersion.
