For the %Cp value of the narrow fraction naphthene base crude oil between 42-50, Cp value refers to that the carbon atom on alkyl side chain accounts for entire molecule
The percentage of total carbon number；
The oiliness improver be sulfurized fatty or ricinoleic acid, in polymerized castor oil acid or smart dimeric dibasic acid any one or
Two or more combinations；
The antirust agent is any one or two or more combinations in boric acid, decanedioic acid or 12 carbon；
The pH adjusting agent is any one or two or more groups in monoethanolamine, triethanolamine or isopropanolamine
It closes；
The surfactant is any one or two or more combinations in span-80, AEO-9 or 90VG；
The fungicide is the combination of any one or two kinds in BK or dicyclohexyl amine；
The narrow fraction naphthene base crude oil is prepared via a method which, is first squeezed into destilling tower naphthene base crude oil, is often subtracted
Pressure distillation, reduced pressure distillation process are 1~65mmHg of residual voltage, cut 300~350 DEG C of distillate, then carry out hydrofinishing, add
The reaction pressure of reaction kettle is 8~15MPa in hydrogen subtractive process, and reaction temperature is 280~360 DEG C, and the total air speed of oil inlet is 0.35
~0.65/h, reaction hydrogen to oil volume ratio is 800~950, relative to hydrotreating catalyst 0.5~0.85/h of air speed, relative to
Hydrobon catalyst air speed 0.85-1.95/h, the catalyst in the unifining process are Mo-W/Al2O3Or Ni-W-
Co/Al2O3, obtain narrow fraction naphthene base crude oil；
The preparation method of above-mentioned environment-friendly type microemulsified cutting fluid is that narrow fraction naphthene base crude oil, oiliness are weighed according to mass percent
Antirust agent, pH adjusting agent is first added in agent, water, antirust agent, pH adjusting agent, surfactant, fungicide and defoaming agent in water
Obtain water base part；Then narrow fraction naphthene base crude oil, oiliness improver and water base part are mixed evenly at 60 DEG C, then again
Surfactant, fungicide, defoaming agent is added to be mixed evenly.
