| 摘要 |
A lubricant film-forming composition includes as a composition: 40 to 80 mass % of a base oil consisting of one or more selected from pentaerythritol fatty acid ester and trimethylolpropane fatty acid ester; 5 to 20 mass % of a solidifying agent consisting of paraffin wax; and 10 to 40 mass % of a solid lubricant consisting of one or more selected from alkali metal salt of hydroxystearic acid and alkali earth metal salt of hydroxystearic acid. A total content of the base oil, the solidifying agent, and the solid lubricant is 85 mass % or more and 100 mass % or less, and the lubricant film-forming composition does not contain heavy metals. |
