ALUMINUM PROCESSING OIL BASE OIL AND LUBRICANT COMPOSITION FOR ALUMINUM PROCESSING
Document Type and Number:
WIPO Patent Application WO/2021/186791
Kind Code:
A1
Abstract:
An aluminum processing oil base oil in which the difference between the 5% distillation temperature determined by the normal pressure method according to JIS K-2254 and the initial boiling point (5% distillation temperature less initial boiling point) is 13°C or less, the difference between the end point determined by the normal pressure method according to JIS K-2254 and the 95% distillation temperature (end point less 95% distillation temperature) is 15°C or less, the surface tension at 25°C determined by the method according to JIS K-2241 is 28 mN/m or less, and the kinematic viscosity at 40°C is from 1.5 mm2/s to 7.0 mm2/s.
