Abstract

Dieses Verfahren zur Herstellung einer homogenen, niedrig-viskosen und Langzeit-stabilen Polymer-Dispersion in Mineralölen, bei dem eine flüssige Mineralöl-Komponente, der ein wasserlösliches Polymer und ein organophiler Bentonit zugesetzt worden sind, gerührt wird, zeichnet sich dadurch aus, dass das Dispergieren mit Drehzahlen >= 1000 Upm durchgeführt wird. Die Dauer des Rührvorganges sollte vorzugsweise zwischen 5 und 60 Minuten liegen und es können sowohl aromatisierte und/oder entaromatisierte Mineralöle als auch typische wasserlösliche Polymere eingesetzt werden, die zudem einen maximalen Wassergehalt von 25 Gew.-% aufweisen können. Mit diesem relativ einfachen Verfahren erhält man bei sehr kurzen Mischzeiten homogene Polymer-haltige Mineralöl-Dispersionen mit niedriger Viskosität und gleichzeitig ausgeprägter Langzeitstabilität, die sich vor allem zur Anwendung in der Öl- und Gasexploration eignen.
