Schmierendwirkende hydraulische Flüssigkeit
Zusatz zu Patent: 122 656
Die Erfindung befaßt sich mit einer hydraulischen Flüssigkeit in Form einer Wasser-in-öl-Emulsion, deren Ölphase ein Mineralschmieröl
ist. Die für viele Verwendungszwecke bestimmte erfindungsgemäße hydraulische Wasser-in-Öl-Flüssigkeit ist flammensicher, {
verschleißfest, beständig und wirkt nicht korrodierend.
In der deutschen Patentschrift 1 122 656 wird eine emulgierbare Mineralölzubereitung beschrieben, die sich aus einem
Schmieröl mit einem Viskositätsindex von mindestens 8o zusammensetzt, das einen Gehalt an Zusatzstoffen von (1) 1 bis 4 G-ewo-?S
eines Monoesters aus einer Fettsäure mit mindestens 8 Kohlenstoffatomen
und aus einem inneren Äther eines aliphatischen

Bs konnte gefunden werden,' daß die obige Ölzubereitung mit einem Gehalt an zwei verschiedenen nicftt-ionischen oberflächenaktiven Mitteln bezüglich der Emulsionsboständigkeit: eigenschaften
der aus ihr erhältlichen Wasser-in-öl-Erculoioi
noch weiter verbessert werden kann. Hierzu wird der Zubereitung ein mit einer Stickstoffbase modifizierter oleophilcr
Ton oder ein Gemisch aus einem derart modifizierten und einem nicht-modifizierten Ton zugesetzt. Die erfindungsgemäße
Ölzubereitung läßt sich ohne weiteres bei ihrer Verarbeitung zu einer flammsicheren hydraulischen flüssigkeit
mit guten Schmiereigenschaften emulgieren. Die dabei erhaltene Flüssigkeit bleibt sowohl unter statischen als
auch unter dynamischen Arbeitsbedingungen über einen weiten Temperaturbereich beständig. Sie ist weiterhin nicht-toxiscl:,
verschleißfest und besitzt korrosionsverhütende und den
Verschleiß verringernde Eigenschaften.
