Abstract

A mineral lubricating oil is thickened to a grease consistency with an alkali metal soap and a sodium phosphate. Sodium orthometa- or pyrophosphate, sodium dihydrogen phosphate or disodium hydrogen phosphate may be used, in amounts (of the total composition) from 2 to 20 per cent. on a hydrated basis or from 0.5 to 10 per cent. on an anhydrous basis. The soap may be prepared from any fatty acid or fatty oil having 12 to 24 carbon atoms per acid molecule, sodium soaps of saturated acids being preferred. The soap may comprise 5 to 40 per cent. of the grease. The oil may be any mineral lubricating oil, especially one of viscosity index of at least 80 and viscosity between 35 and 500 SSU at 210 DEG F. The oil content may be between 55 and 90 per cent. by weight of the grease, preferably 65 to 85 per cent. Additives such as oxidation inhibitors, e.g. phenyl alpha naphthylamine, extreme pressure agents, tackiness agents and metal deactivators may also be present. The greases are preferably prepared by p heating the fatty acid and an equal quantity of mineral oil to about 200 DEG F. and adding caustic soda, preferably as a 50 Be1 solution, the mixture being then heated to about 300 DEG F. to effect dehydration. The phosphate is then added as an aqueous solution, the mixture is further heated and finally the remainder of the mineral oil is added, together with additional oxidation inhibitors or other additives if desired. The mixture is cooled with stirring to about 200 DEG F. and packaged. Tests on various grease compositions are reported in the examples, two specified compositions being (all parts by weight) (1) 22 parts of stearic acid, 69.6 parts of mineral oil (49 SSU at 210 DEG F.; V.I. 45), 4.5 parts of sodium hydroxide and 9.1 parts of hydrated sodium orthophosphate (3.9 parts of anhydrous salt), and (2), 20.5 parts of stearic acid, 29.1 parts of mineral oil (50 SSU at 210 DEG F.; V.I. 80), 43.5 parts of mineral oil (68 SSU at 210 DEG F.; V.I. 80), 3.9 parts of sodium hydroxide, 2.0 parts of anhydrous sodium orthophosphate, and 1 part of phenyl alphanaphthylamine.
