LUBRICATING OIL COMPOSITION FOR HIGH TEMPERATURE

摘要

PROBLEM TO BE SOLVED: To provide a lubricating oil composition for a high temperature in which an evaporation amount at a high temperature when it is in the form of a thin film is suppressed and the flowability is kept for a long period of time. SOLUTION: The lubricating oil composition for a high temperature is obtained by mixing a base oil compound comprising (a) 20-100 wt.% of an aromatic ester compound represented by general formula (I) (wherein R1represents a 6-16C linear alkyl group and n is an integer of 1-6), and (b) 0-80 wt.% of another base oil with (c) 0.1-10 wt.% of an antioxidant based on the total amount of the lubricating oil composition.
