Embodiment Construction

[0017] The present invention is made from following raw materials:

[0018]

[0019] Preparation:

[0020] The first step is to feed the material, close the bottom cut-off door of the refining kettle, put in 600Kg of autoclave melting oil (lithium series base oil A3 is lithium material oil), open the lower wing, stir the inner and outer wings at 45-50Hz, and the temperature rises to 60°C , drop into benzoic acid 59kg, temperature rises to 75-80 ℃, stop gas, keep stirring at constant temperature for 30 minutes, until benzoic acid dissolves. Add 143kg of stearic acid and 300Kg of warm oil (lithium series base oil A3 is lithium material oil), 108Kg of aluminum isopropoxide, stir for 15 minutes and add 108Kg of aluminum isopropoxide for a second time.

[0021] In the second step of replacement reaction, the temperature is raised to 125-130°C, 40-45Kg of pure water is added for replacement, and the mixture is stirred for 20-30 minutes. Continue to heat up (slowly heat up to pr...
