NOVELTY - Antifriction and heat conduction lubricating grease comprises: 65-85 wt.% base oil; 5-20 wt.% thicker; 0.1-5 wt.% antioxidant; 0.1-5 wt.% antirust corrosion inhibitor; and 5-20 wt.% modified graphene. USE - The lubricating grease is useful for motor bearing of pure electric vehicle (claimed). ADVANTAGE - The lubricating grease: has features of antifriction, energy saving and excellent heat conduction performance; satisfies the lubricating requirements of a pure electric vehicle, under the condition of high speed, high temperature, heavy load and extremely low temperature for a motor bearing; reduces the friction coefficient of the motor bearing; saves the electric energy; and has extremely high heat conduction performance, so as to greatly reduce the operation temperature of the bearing, thus prolonging the service life of the bearing.
