Patent ID: 8293693

Claim:
A conductive lubricant composition, comprising a lubricating base oil (A) other than a silicone oil and formed of carbon, hydrogen, and oxygen and comprising 67.7-97.75 mass % based on the total mass of the composition of a monoether compound represented by formula (II): R 6 —O—R 7 (II) wherein one of R 6 and R 7 is a C1 to C24 alkyl group, and the other is a C1 to C24 alkyl group, a phenyl group, or a C7 to C24 alkylaryl group, 0.01 to 10 mass %, based on the total mass of the composition, of a non-metallic antistatic agent (B) which is a condensate product from a polyethylenepolyamine and a fatty acid, and 0.05-10 mass % based on the total mass of the composition of at least one friction modifier (C) which is an amine salt of a phosphate ester, wherein said composition exhibits a kinematic viscosity of 25 mm 2 /s or less at 40° C., a viscosity index of 100 or higher, a flash point, as determined through the COC method, of 150° C. or higher, a pour point of −40° C. or lower, and a volume resistivity of 1.22×10 8 -1×10 10 Ω·cm at 25° C.
