PROBLEM TO BE SOLVED: To provide a lubricant composition excellent in high temperature stability with less evaporation amount even at an elevated temperature. SOLUTION: This lubricant composition with heat stability comprises a lubricant, calcium phosphate and an additive having an anti-oxidant action. The same lubricant composition with heat stability can also be obtained when combined with another thickener. It is preferred that the content of the calcium phosphate is 1-70 mass%, and the content of the additive having an anti-oxidant action is 0.1-10 mass%. When combined with another thickener, the thickener is preferably used in a range of 0.5-20 mass%. The lubricant composition is characterized in less evaporation amount at the elevated temperature and excels in heat stability at the elevated temperature. COPYRIGHT: (C)2010,JPO&INPIT |
