[0038] The second aspect of the present invention is to provide a method for preparing a wire cutting mother solution containing an organic / inorganic additive as described in the first aspect of the present invention, comprising the following steps:

[0039] The engine oil, the main emulsifier, the auxiliary emulsifier, the rust inhibitor, the defoamer, the organic additive, the inorganic additive and water are uniformly mixed to obtain the wire cutting mother liquor containing the organic / inorganic additives, and water is added to dilute the wire cutting mother liquor containing the organic / inorganic additives to obtain the wire cutting liquid containing the organic / inorganic additives.

[0040] As a preferred embodiment, the method comprises the following steps:

[0041] (1) adding the primary emulsifier into the engine oil according to the mass ratio, stirring to make it evenly dispersed, and obtaining liquid a;

[0042] (2) adding the co-emulsifier to water and stirring to make it evenly dispersed to obtain liquid b;

[0046] (6) subjecting the mixture containing the organic / inorganic additive to ultrasonic treatment and vacuum treatment in sequence to obtain a wire cutting mother solution containing the organic / inorganic additive;

[0047] (7) Diluting the wire cutting mother solution containing organic / inorganic additives with water and stirring the mixture to obtain the wire cutting liquid containing organic / inorganic additives.

[0048] As a preferred embodiment, in steps (1), (2), (4), (5) and (7), the stirring time is independently selected from 10-20 min, and the stirring speed is 200-300 r / min; and / or,

[0049] In step (7), the dilution mass ratio of the wire cutting mother liquid containing organic / inorganic additives to water is 1:30-50.

[0050] As a preferred embodiment,

[0051] Step (3), the shear emulsification time is 10-20 min, the temperature is 40-50° C., and the shear rate is 6000-7000 r / min; and / or,

[0052] In steps (5) and (6), the power of the ultrasonic treatment is independently selected from 5-180 min, and the power of the ultrasonic treatment is independently selected from 50-300 W; further preferably, in step (5), the power of the ultrasonic treatment is 45-180 min, and the power of the ultrasonic treatment is independently selected from 100-300 W; in step (6), the power of the ultrasonic treatment is 5-20 min, and the power of the ultrasonic treatment is independently selected from 50-100 W; and / or,

[0055] In the wire cutting fluid of the present invention, the organic additive triethanolamine borate will produce physical adsorption on the surface of the friction pair and form a friction boundary film. The inorganic additive Ti3C2 MXenes of the present invention can spontaneously form a lubricating film and repair the wear surface between the friction pairs, thereby reducing the contact area between the friction pairs to achieve a friction reduction effect. At the same time, the shear between the MXene sheets under the action of shear force is easy to form a sliding system of friction contact, thereby reducing the friction between the friction pairs. During the reciprocating motion of the friction pair, its contact surface will gradually become rough. Since the Ti3C2 MXenes material is ultrasonically treated before addition, a larger interlayer spacing is obtained under the action of ultrasonic treatment, so the interlayer sliding between the Ti3C2 MXenes nanosheets is easier. At the same time, under the action of friction, Ti3C2 MXenes and triethanolamine borate are broken into smaller fragments, and flow into the wear area with the emulsion, fill the pits and form a physical adsorption film, and through the synergistic effect of the two, the friction coefficient is reduced, and the wear between the friction pairs is reduced. The present invention also finds that the two also have a synergistic anti-rust effect.

[0056] The beneficial effects of the present invention are:

[0057] Compared with the existing commercial cutting fluids on the market, the cutting fluid containing organic / inorganic additives of the present invention has better lubrication and friction reduction performance and rust prevention performance, and has the advantages of low environmental pollution, etc., which is more obvious under high speed and high load conditions.

[0143] It uses an equal mass of water to replace inorganic additives and organic additives.

[0144] The test method is as follows:

[0145] Lubrication and friction reduction performance: The friction test was carried out using a UMT-5 friction and wear tester at room temperature of 20°C. The friction pairs were made of GCr15 steel, the diameter of the grinding balls was 8mm, the diameter of the lower plate sample was 24mm, and the height was 8mm. The friction form was linear reciprocating motion, and the friction frequency was 6Hz. After the friction test, the surface morphology of the friction pair was analyzed using a three-dimensional white light interferometer surface profiler.

[0146] Anti-rust performance: There are three common anti-rust test methods for wire cutting working fluid: single-piece anti-rust test method, stacked anti-rust test method and iron scrap anti-rust test method. For the sake of uniformity, the test of the anti-rust performance of the sample is carried out according to the method specified in GB6144-85. The cast iron test piece is polished with corundum sandpaper, scrubbed with absorbent cotton dipped in anhydrous alcohol, and blown dry with a hair dryer. The sample dilution is taken with a pipette, and five drops are dropped on the smooth surface in a plum blossom format (each drop has a diameter of 4 to 5 mm). The test piece is placed on the dryer partition (a small amount of water is placed at the bottom of the dryer), covered with a glass cover, and placed in a thermostat that has been kept at a constant temperature of 35±2℃. The experiment is continued for 24 hours and then taken out for observation. If there is no rust on all five drops, it is qualified as Grade A, four drops are rust-free as Grade B, three drops are rust-free as Grade C, and two drops are rust-free as Grade D.

[0147] Conductivity: This study uses a DDS-307A conductivity meter to test the conductivity of the emulsion. When in use, the electrode is immersed in the solution to be tested. When the reading on the display screen stabilizes, it is the conductivity value of the measured solution.

[0148] Emulsion stability: Place the working solution at room temperature (15-35°C) for several days (180 days) and observe the time for the soap or oil layer to precipitate. This is used as a standard for evaluating the emulsion stability of the working solution.

[0149] Defoaming performance test: Pour an appropriate amount of emulsion into a 100mL measuring cylinder, make the liquid level at 70mL, cover the stopper, shake up and down for 1min, and the shaking frequency is 100-200 times / min. Then, let it stand at room temperature for 10min, observe the volume of residual foam on the liquid surface, and it is qualified if it is no more than 3mL.

[0150] The wire cutting fluids of the above embodiments and comparative examples were tested, and the results obtained are shown in Table 1:

[0151]

[0152]

[0153] From the results in Table 1, it can be seen that the organic additives and the inorganic additives in the wire cutting fluid of the present invention have a synergistic effect, and the wire cutting fluid of the present invention has good lubrication, friction reduction and rust prevention properties. In addition, the wire cutting fluid of the present invention has good emulsion stability and conductivity.

[0154] The wire cutting fluid of the present invention has good emulsion stability, that is, the stable emulsion can maintain uniformity and stable physical and chemical properties for a long time, which helps to ensure uniform lubrication and cooling effects during the processing, avoids uneven cooling due to emulsion instability, and thus improves the processing accuracy and consistency. Therefore, the stability of the emulsion can ensure effective control of temperature during the cutting process, thereby reducing thermal deformation of the workpiece surface and ensuring cutting accuracy.

[0155] The wire cutting fluid of the present invention has good electrical conductivity and can improve the efficiency of electric spark discharge, thereby improving the processing speed and processing quality.

[0156] In summary, the cutting fluid mother liquor of the present invention is prepared by mixing a base emulsion with organic additives and inorganic additives having synergistic effects, and is a water-based cutting fluid having the advantages of good cooling, rust prevention, electrical conductivity and low pollution.
