Description
Technical field
The invention discloses a kind of preparation method of safe environment protection type metalworking fluid, belongs to cutting fluid technology of preparing neck
Domain.
Background technology
It is to improve stock-removing efficiency in metal cutting process, improves the precision of workpiece and reduce workpiece surface roughness, prolongs
Long cutter life, optimal economic effect is reached, must just reduce the friction between cutter and workpiece, cutter and chip,
The heat produced because material deforms in cutting region is taken away in time.These purposes are reached, is on the one hand by developing high rigidity
The geometry of resistant to elevated temperatures cutter material and improvement of cutter；On the other hand the cutting fluid of function admirable is adopted to improve cutting effect
Rate, reduces workpiece surface roughness, and tool life obtains good economic benefit.
Good lubrication, cleaning and antirust can be played in metal cutting process from suitable metalworking fluid
Deng effect, so as to improve tool life, it is ensured that crudy and machining accuracy, improve production efficiency.Cutting fluid is a kind of use
Cut, cut, grinding in the course of processing in metal, for cooling down and lubricating the industrial type fluid of cutter and workpiece, cutting fluid possesses good
Good cooling performance, greasy property, rustless property, oil removing cleaning function, anti-corrosion function, easily dilutable feature.
Presently used cutting fluid includes oil base cutting fluid and water-base cutting fluid, wherein, the greasy property of oil base cutting fluid
Preferably, cooling effect is not good, biological degradability and less stable, has substantially lagged behind sending out for modern Machining Technology for Cutting
Exhibition；Preferably, cost is lower than oil base property, and its consumption accounts for the percentage of whole cutting fluids for water-base cutting fluid cooling effect and cleaning performance
95, but because water-base cutting fluid major part is as antirust agent, using chlorinated paraffin its profit to be increased using sodium nitrite
Slip, it is commonly known that excessive chlorine element is a kind of to material of the human body with evil, and the harm to environment is also very big, is not inconsistent cyclization
The requirement of guarantor, and the greasy property of water-base cutting fluid is relatively weak.Therefore, develop environmental type cutting liquid product has become one
Plant main trend.
The content of the invention
Present invention mainly solves technical problem：For containing harmful material in existing cutting fluid, while
Can be to environment, and the weaker defect of greasy property of cutting fluid, there is provided a kind of to be prepared by animal oil and triglyceride

During number is for the beakers of 2% sodium hydroxide solution, 15~20min is soaked, in transferring to high-speed tissue mashing machine, with 4500~
The rotating speed of 5500r/min crushes 20~30min, obtains homogenate, and homogenate is poured in beaker, and it is carried out to be heated to 35
~40 DEG C, add 2~4g trypsin and 3~5g phospholipase, stirring 3~4h of enzymolysis；
（2）Treat that enzymolysis terminates, after enzymatic hydrolysate is mixed with 0.3~0.5g tert-butyl hydroquinone, in pouring autoclave into,
Under nitrogen protection 20~30min is processed with the condition of 120~130 DEG C, 0.3~0.5MPa, then the material after process is placed in
In centrifuge, 15~20min is centrifuged with the rotating speed of 4500~5000r/min, collects upper strata oils and fatss, obtain final product fish oil；
（3）In mass ratio it is 100 by above-mentioned fish oil, glycerol and sodium hydroxide:10:1, in being added to reactor, control reactor
Temperature is 130~140 DEG C, and 3~4h of stirring reaction, reaction terminates, and is cooled to 25~35 DEG C, and add 100 in reactant liquor~
200mL water, after stirring 2~4min of mixing, stratification, collected organic layer, and being placed on organic in beaker, add 5~
8g activated carbons, after standing 1~2h, filter, and collect filtrate, standby；
（4）200~300g Flos Loniceraes are weighed, in being added to the beaker for filling 600~700mL dehydrated alcohol, 12~14h is soaked
Afterwards, beaker is placed in microwave extracting reaction instrument, control abstraction instrument power for 280~300W, extracting pressure for 0.12~
0.15MPa, radiates 15~20min, and extraction terminates, and by the semi-transparent membrane filtration that extracting solution aperture is 80~120nm, collects filter
Liquid, and be spray-dried, obtain dried object；
（5）Count by weight, weigh 40~50 parts of steps（3）Standby filtrate, 8~12 parts of above-mentioned dried objects, 12~15 parts
Calcium gluconate, 3~5 parts of tea saponins, 1~3 part of potassium sorbate and 40~50 parts of water, in being added to blender, stirring mixing 15
~20min, you can obtain safe environment protection type metalworking fluid.
