Described auxiliary agent is made up of the raw material of following weight portion: artificial diamond stone powder 2-3, corundum 1-2, acrylonitrile 1-2, Oleum Bupleuri 3-4, Lauryl Alcohol ester 2-3, abienol 2-3, hexamethyl disiloxane 1-1.5, dodecylbenzene sodium sulfonate 3.5-4, water 50-54；Preparation method be first by artificial diamond's stone powder, corundum, Oleum Bupleuri, dodecylbenzene sodium sulfonate add half amount water in, grind 1-2 hour, it is then slowly added into all the other residual componentss, it is slowly heated to 70 DEG C-80 DEG C, stirring reaction 30-50 minute under 300-500 rev/min of condition, is cooled to room temperature and get final product。
A kind of finely dispersed aqueous cutting fluid of steady quality of the present invention, is made up of step in detail below:
(1) by Tween-80, Oleum Ricini, ricinoleic acid soda soap, nano silicon mix homogeneously, adding appropriate deionized water, heating, to 30 DEG C-35 DEG C, is ground 30-40 minute, obtains mixing A material；
(2) all the other residual componentss except auxiliary agent are joined in reactor, be uniformly mixed, be slowly heated to 55 DEG C-65 DEG C, be incubated 1-1.5 hour, obtain mixing B material；
(3) expect the mixing B of insulation to be slowly added into while stirring in mixing A material, after being sufficiently stirred for, add auxiliary agent, 800-900 rev/min of lower stirring reaction 50-60 minute, it is cooled to room temperature and get final product。
The excellent effect of the present invention is: abrasive material nano silicon is mixed mutually with surfactant by the present invention by grinding technics, not only increase wearability, and abrasive material is uniformly dispersed, improve the quality of cutting fluid, compounding aid, enhance wear-resistant, dispersion, lubrication, film property；The present invention has the lubrication abrasion resistance of excellence, cleans cooling and corrosion-resisting resisting resistance, it is possible to avoids the generation of BUE, is effectively protected cutter, improves crudy, simple to operate, with low cost。
