<p>The lubricant composition of the present invention is characterized in that 1 ppm to 500 ppm of polysiloxane with a viscosity of 1,000 mm2/s to 100,000 mm2/s at 40 °C and 1 ppm to 5,000 ppm of ethylene glycol-propylene glycol polymer or a derivative thereof are blended with a base oil with a viscosity of 10 mm2/s to 700 mm2/s at 40 °C. Because the lubricant composition of the present invention has excellent anti-foaming property, particularly in lubricants of high viscosity and at higher temperature, the composition is useful as a lubricant composition for use as bearing oil such as a lubricant for paper machine, hydraulic oil for injection molding press, and a lubricant for film orientation machine.</p> |
