Embodiment 2

[0016] The oxidation resistance of Example 2 is worse than that of Proportion 1, but the stability of the formula system is not as good as that of Proportion 1. In Example 2, some additives will be slightly precipitated at low temperature, and the cost is also higher.

[0017] To sum up, we feel that ratio 1 is more economical and more scientific.

[0018] The gear oil and the preparation method thereof in the embodiment of the present invention have excellent high temperature stability, prevent oil from oxidative deterioration and deposit formation, and keep the gearbox clean. Excellent anti-wear protection, effectively prolonging the service life of components. Improved friction characteristics to ensure continuous, reliable and trouble-free operation of the transmission. Good friction stability and smoother gear shifting.

Abstract

The embodiment of the present invention discloses a gear oil, which comprises the following components by weight percentage: 1.5% polymethyl methacrylate, 0.3% V1156 pour point depressant, 0.3% di-tert-butyl-p-cresol, dialkyl dithio Zinc phosphate 2%, bis-succinimide 1%, friction system improver 0.5%; antifoaming agent 0.0001%, pigment 0.0001%, and the rest is base oil. A preparation method of the above-mentioned cleaning agent is also disclosed. The above raw materials are stirred and mixed evenly at room temperature; the gear oil and its preparation method of the embodiment of the present invention have excellent high temperature stability, prevent oil from oxidative deterioration and deposit formation, and keep the gearbox clean. Excellent anti-wear protection, effectively prolonging the service life of components. Excellent friction characteristics to ensure continuous, reliable and trouble-free operation of the transmission. Good friction stability and smoother gear shifting.

Description

technical field [0001] The invention relates to the field of gear oil, in particular to a gear oil and a preparation method thereof. [0002] Background technique. [0003] Automatic gear oil is mainly used in automatic transmission systems of cars and light trucks, transmissions and power steering systems of large trucks. Generally speaking, its function is to transmit the power of the engine, form the shift oil pressure, and lubricate the various parts in the automatic transmission. In the process of automatic shifting, automatic transmission oil is the medium of transmission pressure, and it also plays the role of lubricating the planetary gear set inside the transmission, protecting the friction plates of the shifting clutch, and helping the moving parts in the automatic transmission to dissipate heat. Automatic gear oil can make the car automatically adapt to the impact of driving resistance, improve the power performance of the car, keep the engine in the best conditio...
