Abstract
Official abstract text for this publication.
A silicone modified lubricant includes a Group I, II, III, IV or V base oil in combination with a minor amount of a silicone oil. Further, the lubricant includes a dispersant such as a dispersant olefin copolymer which maintains the silicone oil dispersed in the base oil. The silicone oil reduces the surface tension of the lubricant thereby reducing power loss. Preferably the lubricant formation has a surface tension less than 28 mN/m, making it particularly suitable for dip lubrication systems.
First claim
Opening claim text (preview).
What is claimed is: 1 . A lubricant formulation comprising: a base oil selected from a Group consisting of Group I, Group II and Group III and Group IV base oil and combinations thereof; 01 to 5% silicone oil; and a dispersant olefin copolymer in an amount effective to maintain said silicone oil dispersed in said base oil, wherein said olefin copolymer is soluble in said base oil. 2 . The lubricant claimed in claim 1 wherein said dispersant olefin copolymer is an ethylene propylene copolymer. 3 . The lubricant formulation claimed in claim 2 , wherein said dispersant olefin copolymer has an ethylene propylene ratio of 55/45 -45/55. 4 . The lubricant formulation claimed in claim 1 , wherein said dispersant olefin copolymer is an ethylene propylene diene terpolymer. 5 . The lubricant formulation claimed in claim 1 , having 0.02 to 0.5% silicone oil. 6 . The lubricant formulation claimed in claim 1 , having 0.1 to 10% olefin copolymer. 7 . The lubricant formulation claimed in claim 1 , wherein said base oil is a Group III base oil. 8 . The lubricant formulation claimed in claim 1 , comprising 40-95% PAO. 9 . The lubricant formulation claimed in claim 1 , comprising 0.01 to 15% nanographite particles. 10 . The lubricant formulation claimed in claim 1 , wherein said base oil includes at least 40% of a Group III or Group IV base oil. 11 . The lubricant formulation claimed in claim 5 , comprising 40 to 95% by weight of said base oil. 12 . The lubricant formulation claimed in claim 1 , having a surface tension less than 28 mN/m. 13 . The lubricant formulation claimed in claim 12 , having a surface tension less than or equal to 25 mN/m. 14 . The lubricant formulation claimed in claim 5 , having 0.02 to 0.5% defoamers.
