8. the preparation method of lube oil additive described in claim 5, it is characterised in that：Including following processing steps：
S1 will under nitrogen atmosphereh- BN powders are 1 in mass ratio with acetamide:20~1:40 mixing, in planetary ball mill into
Row ball milling, 500 ~ 1000 r/min of rotational speed of ball-mill, Ball-milling Time is at least for 24 hours；Powder after ball milling is placed in water, is impregnated at least
72h, it is dry, it obtainsh- BN nanometer sheets；
Additive raw material is mixed in sealing device by material rate, is excluded in sealing device using nitrogen after mixing by S2
Then air carries out it ultrasonic disperse, 1 ~ 6h of jitter time obtains suspension,
S3, by PAO, viscosity index improver, pour-point depressant, suspension obtained by S2 is placed in Group III base oil in proportion, and 70 ~ 90
At least 1h is stirred at DEG C, both.
