Abstract:
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.

Abstract:
A lubricating grease composition comprising (A)a base oil,(B)5 to 10 wt.% of a urea compound, (C) 0.5 to 20 wt.% of at least one phosphorous compound selected from the group consisting of a phosphoric acid salt etc., and(D)0.5 to 40 wt.% of a fatty acid metal salt. Aforementioned lubricating grease composition allows it to reduce the friction coefficient and prolong the endurance life significantly when it is applied onto surfaces of the sliding pair consisting of metal and plastic (especially glass-fiber-reinforced plastic) parts.
Abstract:
A lubricant additive for gear oils and an improved gear oil are disclosed. The additive comprises about 0.01 to about 65 percent, by weight, of solid lubricant particles selected from the group consisting of molybdenum disulfide, graphite, cerium fluoride, zinc oxide, tungsten disulfide, mica, boron nitrate, boron nitride, borax, silver sulfate, cadmium iodide, lead iodide, barium fluoride, tin sulfide, fluorinated carbon, PTFE, intercalated graphite, zinc phosphide, zinc phosphate, and mixtures thereof; combined with about 0.1 to about 25 percent, by weight, of a stabilizing agent consisting of an ethylene-propylene copolymer; and a fluid carrier. The lubricant additive provides the gear oil with improved demulsibility, stability, and compatibility characteristics of the gear oil when contaminated with water.
Abstract:
A water-soluble metal-working composition is provided which comprises a relatively large alkoxylated amine, an alkanolamine and an acid-derived compound selected from organic acids, inorganic acids, and salts thereof.
