(2) Xylo-Mucine is added in deionized water, stir 10 minutes to dissolving completely, then sorbester p17 is added, 10 minutes are stirred with the speed of 600-800 rev/min, obtain dispersion liquid, continue to add nano silicon carbide boron particles, stir and obtain suspension in 10-15 minute, then suspension is placed in ultrasonic cleaning instrument ultrasonic disperse after 15-20 minute spraying dry obtain modified Nano boron nitride particle;
(3) tricarboxymethyl propane oleate of half amount is put into stirring, add hydroxyethyl imidazole quinoline, the modified Nano boron nitride particle that step (2) obtains is added after stirring 15-20 minute with the speed of 300-400 rev/min, continue to stir 30-40 minute, until be uniformly dispersed, obtain antifriction antiwear and strengthen base oil;
(4) tricarboxymethyl propane oleate of residual content is put into reactor, add polymethacrylate, zinc dialkyl dithiophosphate, continue to be heated to 100-120 DEG C, constant temperature stirs 60-90 minute, be cooled to 60-70 DEG C, add methyl-silicone oil, fluorosilicon oil and all the other remaining components except antifriction antiwear strengthens base oil, 3 times are ground through triple-roller mill after stirring, continue to add antifriction antiwear and strengthen base oil, room temperature is slowly cooled to after dispersed with stirring is even, eventually pass 3 grades and filter rear barrelling, get product.
