The invention relates to lubricating grease compositions, having a base oil mixture based on oils having viscosities (ISO VG 2 to ISO VG 1500) that are standard for industrial lubricants, an ionic liquid, a thickening agent, e.g. based on a polyurea compound and conventional additives that can be used at current service temperatures that are higher than 120°C to 260°C, in particular at a service temperature in the region of high service temperatures that are higher than 180°C to 260°C and also at low temperatures as low as -6O°C. The invention also relates to a method for producing said type of lubricating grease compositions.
L'invention concerne des compositions de lubrifiants, comprenant un mélange d'huiles de base composé d'huiles présentant des viscosités (ISO VG 2 à ISO VG 1500) courantes pour des lubrifiants industriels, un liquide ionique, et un épaississant, par exemple à base d'un composé polyurée ainsi que des additifs courants, qui peuvent être utilisées à des températures d'utilisation courantes comprises entre 120 et 160°C, en particulier à une température d'utilisation haute température comprises entre 180 et 260°C mais également basse température allant jusqu'à -60°C. L'invention concerne également un procédé de production desdites compositions de lubrifiants.
