PURPOSE:To provide a novel solid lubricant composition which can be used without causing scattering, tunneling, etc., and is suitable for the metal working such as marking, cutting, grinding, etc., by impregnating specific amounts of an oiliness improver and an extreme pressure agent in an inorganic carrier having specific density and oil absorption. CONSTITUTION:100pts.wt. of an inorganic carrier (pref. white carbon, calcium silicate-gypsum composite, etc.) having an apparent density of >=0.15g/cc and an oil absorption of >=0.5ml/g, is impregnated with >=30pts.wt. of an oiliness improver and/or an extreme pressure agent to obtain the objective lubricant composition. Pref. the oiliness improver is selected from mineral oils, animal or vegetable oils, synthetic oils, and higher fatty acids, and the extreme pressure agent is selected from organic sulfonic acids, aromatic carboxylic acids, phosphorus-containing organic compounds, sulfur-containing organic compounds, and halogen-containing organic compounds. EFFECT:Waste water treatment after use is easy. |
