in the fourth step, the solid filler selected in the first step is subjected to ultrasonic high-speed dispersion treatment, then the dispersed solid filler is placed in the rotating dispersing agent in the first step to be stirred and mixed to obtain dispersed filler, and then the dispersed filler is subjected to ultrasonic high-speed dispersion treatment again;
in the fifth step, the additive obtained in the third step and the dispersed filler obtained in the fourth step are placed in the mixture obtained in the second step together to be stirred to obtain a semi-finished product, and the heat preservation can be stopped after the stirring is finished;
and in the sixth step, naturally cooling the semi-finished product obtained in the fifth step, cooling the semi-finished product by using dry ice or liquid nitrogen when the semi-finished product is cooled to normal temperature, stirring the semi-finished product in the cooling process so as to uniformly cool the semi-finished product, removing the dry ice or the liquid nitrogen when the temperature of the semi-finished product is cooled to 10-15 ℃, filtering the semi-finished product by using a vacuum oil filter, and standing the obtained filtrate for 60-80min to obtain the lubricating oil.
3. The functional lubricating oil with good comprehensive performance as claimed in claim 1, wherein: the composite pour point depressant is prepared by mixing a polyacrylic acid higher alcohol ester pour point depressant and a polyolefin pour point depressant according to the weight ratio of 3: 2.
4. The functional lubricating oil with good comprehensive performance as claimed in claim 1, wherein: the anti-foaming agent is prepared by mixing dimethyl silicone oil and a non-organic silicon polymer anti-foaming agent according to the weight ratio of 1: 1.
5. The functional lubricating oil with good comprehensive performance as claimed in claim 1, wherein: the solid filler is prepared by mixing graphite, molybdenum disulfide, polytetrafluoroethylene and nano metal powder according to the weight ratio of 2: 1.
6. The functional lubricating oil with good comprehensive performance as claimed in claim 1, wherein: the detergent is high-base number synthetic calcium sulfate T106.
7. The process for processing the functional lubricating oil with good comprehensive performance as claimed in claim 2, wherein the process comprises the following steps: in the fourth step, the ultrasonic frequency is 20-30KHz, the dispersion speed is 4000-4500r/min, and the dispersion time is 20-30 min.
8. The process for processing the functional lubricating oil with good comprehensive performance as claimed in claim 2, wherein the process comprises the following steps: in the fifth step, the stirring time is 60-90min, and the stirring speed is 400-500 r/min.
