Summary:PURPOSE:A high-temp. lubricant composition with excellent lubricating performance free from fear of pollution of working environment, which comprises a graphite powder, an alkylene glycol or polyglycol, and a dispersant. CONSTITUTION:50-94wt% graphite powder, 5-40wt% alkylene glycol or polyglycol, and 0.1-10wt% dispersant are compounded. Since some alkylene glycols or polyglycols have their own dispersing function, a pref. proportion for compounding depends on a kind of the alkylene glycol or polyglycol. In the case of a 2-4C alkylene glycol, the graphite powder, alkylene glycol and dispersant are pref. compounded, in an amt. of 70-90wt%, 10-30wt% and 3-10wt%, and in the case of a 5C or higher alkylene glycol, in an amt. of 60-90wt%, 10-30wt% and 2-10wt%, respectively.
