Abstract

Le fluide fonctionnel à usage multiple ci-décrit consiste en une quantité importante d'une huile d'hydrocarbure et en une petite quantité, suffisante pour améliorer les caractéristiques du fluide, d'un nouvel additif. L'additif consiste en un complexe de sel de calcium, un sel de dithiophosphate d'un métal du groupe II, un époxyde de borate et un solubilisant carboxylique. Le sel de calcium se présente de préférence sous la forme d'un sel de sulfonate de calcium surbasé, l'agent anti-usure est de préférence un sel de dithiophosphate de zinc, l'époxyde de borate est de préférence le produit de réaction de l'acide borique et 1,2-époxyde ayant 16 atomes de carbone, et le solubilisant carboxylique se présente de préférence sous la forme d'un produit de réaction d'un agent d'acylation contenant un substituant à base d'hydrocarbyle substitué contenant entre 12 et 500 atomes de carbone. D'autres composants tels que des agents d'amélioration de la viscosité et un agent anti-mousse sont généralement présents dans le fluide. Le fluide résultant présente de meilleures caractéristiques de filtration et de fluidité à basse température, des caractéristiques améliorées EP/anti-usure, d'excellentes propriétés d'amélioration de la friction, anti-broutage et passent les tests de transmission hydraulique, de servo-direction et de freinage. Ces caractéristiques sont maintenues simultanément sans nuire à d'autres caractéristiques de performance désirable du fluide. Les caractéristiques de performance EP/anti-usure sont maintenues conjointement aux caractéristiques d'anti-corrosion et aux capacités de transmission. La tolérance à l'eau améliorée est maintenue conjointement aux caractéristiques améliorées de performance EP.
