Mix, stratification 8 after stirring 3～5h of mixing～
10h, takes upper oil phase, standby；Described lauric acid acetone mixed solution is by lauric acid and acetone in mass ratio 1:8 mixing；
（4）Weigh 4～8g superfine heavy calcium carbonates to be added in 80～100mL deionized waters, after 5～10min of ultrasonic disperse
Suspension, by suspension heating in water bath to 70～80 DEG C, adds 1～2g aluminate coupling agent F-1 after 20～30min of stirring,
And with 1500～1700r/min rotating speeds stirring 3～4h of mixing, in adding centrifugal separator after stirring, with 5000～7000r/min
Rotating speed 15～20min of centrifugation, is put into after obtaining precipitate in baking oven, in 60～80 DEG C of 8～10h of drying, you can be modified
Calcium Carbonate；
（5）Weigh the above-mentioned modified calcium carbonates of 2～3g and be added to step（3）In standby oil phase, the ultrasound under the conditions of 60～80KHz
8～10min of vibration, is obtained good dispersion additive for wear resistance of lubricating oil after sonic oscillation.
