Title:
LUBRICANT COMPOSITION BLENDED WITH OXIDATION SUPPRESSING CATALYST
Document Type and Number:
Japanese Patent JP2017019910
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lubricant composition having excellent effect of suppressing oxidation deterioration in a lubricant composition such as ester oil, PAO and mineral oil used for a rolling bearing or the like.SOLUTION: A lubricant composition contains anatase type titanium oxide particles. It is preferable that an average primary particle diameter of the titanium oxide particles is 100 nm. It is more preferable that 0.5 to 5 mass% of the titanium oxide particles are contained with respect to the total amount of lubricant. The lubricating oil can be added to generally used oil such as mineral oil, synthetic oil or vegetable oil without a problem or restriction.EFFECT: Lubricating oil blended with the anatase type titanium oxide particles has small total oxidation rise amount and kinematic viscosity rise rate, and significant effect of suppressing oxidation deterioration of a lubricating oil composition.SELECTED DRAWING: None
