Document Type and Number:
Japanese Patent JP3476916
Kind Code:
B2
Abstract:
PURPOSE: To obtain a lube oil composition being lube oil having a high viscosity (VG ≤68) and excellent in defoaming property at a high temperature and used for bearing oil such as lube oil for papermaking machines, hydraulic oil for injection molding machines and lube oil, etc., for film stretching machines, etc.
CONSTITUTION: This lube oil composition is obtained by blending a base oil having 10mm2/s to 700mm2/s viscosity at 40°C with 1ppm to 500ppm of an organopolysiloxane having 1000mm2/s to 100000mm2/s viscosity at 40°C and 1ppm to 5000ppm ethylene glycol-propylene glycol polymer or its derivative.
