Patent number: 8809243Abstract: Water-based lubricants for the lubrication of frictional partners in drive elements, as well as their use. In particular, a water-based lubricant that contains 5 to 80% by weight of water-soluble polyalkylene glycol that is selected from the group that is composed of statistically distributed polyoxyethylene units and/or polyoxypropylene units and/or other polyoxyalkylene components, a block polymer that that is composed of polyoxyethylene units and/or polyoxypropylene units and/or other polyoxyalkylene components, 0.5 to 20% by weight of foaming or non-foaming emulsifiers from the class of anionic, non-ionic, or cationic surfactants, water-soluble or water-emulsifiable carboxylic acid esters, 0.5 to 50% by weight of anti-icing additives, selected from the group that is composed of alkylene glycol, glycerol, salts or ionic liquids, 0.05 to 10% by weight of corrosion additives, 0.001 to 1% by weight of additives for preventing the formation of foam, and 0.Type: GrantFiled: August 23, 2010Date of Patent: August 19, 2014Assignee: Klüber Lubrication München KGInventors: Martin Schmid-Amelunxen, Martin Schweigkofler, Thomas Kilthau, Jochen Muehlemeier

Patent number: 8258088Abstract: 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.Type: GrantFiled: May 20, 2008Date of Patent: September 4, 2012Assignee: Klüber Lubrication München KGInventors: Günther Bodesheim, Martin Schmidt-Amelunxen, Dieter Sohn, Stefan Grundei, Andrea Höpke
