摘要:
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 −60° C. The invention also relates to a method for producing said type of lubricating grease compositions.
