PROBLEM TO BE SOLVED: To provide a lubricant composition having excellent stability against mechanical shear without deteriorating the heat resistance, temperature-viscosity characteristics and damper characteristic in spite of silicone grease base using silicone oil as base oil. SOLUTION: The silicone grease based lubricant composition has an inorganic thickener and a solid lubricant added into the silicone oil of the base oil. The silicone oil has 50-1,000,000 mm<SP>2</SP>/sec kinetic viscosity at 25°C and is at least one kind selected from dimethyl silicone oil and methyl phenyl silicone oil. Hydrophobic fine powder silica gel having fine pores is used as the inorganic thickener. The hydrophobic fine powder silica gel preferably has 2-15μm average particle diameter and 0.4-2 mL/g pore volume. COPYRIGHT: (C)2011,JPO&INPIT |
