preparation example Construction
[0060] A method for preparing a water-based metal cutting fluid, the preparation method is applicable to the above-mentioned water-based metal cutting fluid; the steps of the method are as follows:
[0061] S1: Put diethylene glycol borate, polyethylene glycol, sodium benzoate, trisodium phosphate, simethicone oil, sulfurized calcium alkylphenate into the mixer according to the ratio of deionized water, and heat up to 75-85°C. Stir for 8-12 minutes;
[0062] S2: first lower the temperature in the mixer to 45-50°C, then put triethanolamine, vegetable oil, polysilicon ester, methyl butynol and dispersant into the mixer in proportion, and stir for 30-35 minutes;
[0063] S3: Take out the mixture in the mixer and put it into the filter, filter the material with a 200-mesh filter, which is the cutting fluid product.
[0064] As an embodiment of the present invention, the filter machine described in S3 includes a filter bucket 1; The bottom end is provided with a discharge port 12...
Embodiment approach
[0066] As an embodiment of the present invention, a group of second grooves 3 are provided on the side wall of the cleaning plate 2 close to the filter screen 191, and the second grooves 3 are located between the first grooves 21; the annular grooves A pair of symmetrically distributed third grooves 31 are provided on the side wall of 18; a second rotating shaft 33 is rotatably connected to the side wall of the third groove 31, and the second rotating shaft 33 runs through the first cleaning plate 2. The groove 21 and the second groove 3; the push block 22 is provided with a through groove 34, and the axis of the second rotating shaft 33 passing through the first groove 21 is located in the through groove 34; the second rotating shaft 33 is located in the through groove 34; A pair of symmetrically distributed rotating rods 35 are fixedly connected to the shaft of the second groove 3, and a collision ball 36 is fixedly connected to the end of the rotating rod 35; the collision b...

Abstract
The invention belongs to the technical field of metal cutting fluids, and particularly relates to a water-based metal cutting fluid and a preparation method thereof. The preparation method includes the steps that S1, putting diethylene glycol borate, polyethylene glycol, sodium benzoate, trisodium phosphate, simethicone, sulfurized calcium alkyl phenolate and deionized water into a stirrer according to the proportion, increasing the temperature to 75-85 DEG C, and stirring for 8-12 minutes; s2, firstly reducing the temperature in the stirrer to 45-50 DEG C, then putting triethanolamine, vegetable oil, poly-silyl ester, methyl butynol and a dispersing agent into the stirrer in proportion, and stirring for 30-35 minutes; and S3, taking out the mixture in the stirrer, putting into a filter, filtering by using a 200-mesh filter screen, and discharging to obtain the cutting fluid product. According to the water-based metal cutting fluid and the preparation method thereof, the problems that when a solution is filtered, a filter screen is generally adopted for direct filtering, but when the filtering requirement for the solution is high, holes of the filter screen are small, so that the filtering efficiency is low, and even the filter screen is blocked and liquid cannot be discharged occur are solved.
Description
technical field [0001] The invention belongs to the technical field of metal cutting fluid, in particular to a water-based metal cutting fluid and a preparation method thereof. Background technique [0002] The metal cutting fluids widely used in my country's metal processing industry are mainly emulsified oil products. More than 80% of these products are mineral oils. After adding water, they become milky and have a certain viscosity. Metal cutting fluid is a high-energy-consuming product that consumes a large amount of petroleum product resources. [0003] In the prior art, there are also some technical solutions about metal cutting fluids. For example, a Chinese patent with application number 2009100682103 discloses a water-based reactive multifunctional metal cutting fluid and its preparation method. Its composition formula is surfactant, Solvent, vegetable oleic acid, triethanolamine, sodium salt with corrosion inhibition function, corrosion inhibitor, dimer acid, defo...
