Title:
FLAME-RETARDANT LUBRICANT COMPOSITION
Document Type and Number:
Japanese Patent JP2022045470
Kind Code:
A
Abstract:
To provide a flame-retardant lubricant composition that has excellent flame retardancy and a long service life and can be used for a long time.SOLUTION: A flame-retardant lubricant composition contains, as base oil, a phosphate derivative, MoS2, a lithium soap or diurea compound, and an antioxidant. The phosphate derivative has a repeat unit represented by the formula (A1), one end of which has a structure represented by the formula (A2), the other end of which has a structure represented by the formula (A3), the kinematic viscosity at 40°C of 100 cSt or more and 200 cSt or less. Preferably, the antioxidant is a neutral phosphite derivative and a 2,6-di-t-butyl phenol derivative.SELECTED DRAWING: None
