preparation example Construction

[0039] Another embodiment of the present invention discloses a method for preparing a water-based metal cutting fluid, comprising the following steps:

[0040] A) Mix isovaleric acid and drying oil, add catalyst X, stir, and heat reaction at 150-250°C to obtain light yellow mixed liquid;

[0041] B) Mix the light yellow mixed solution with polyethylene glycol 400, add catalyst Y, stir, and heat at 150-250°C for reaction to obtain partially acidolyzed dry oil polyethylene glycol ester;

[0042] C) Mix and disperse partially acid-hydrolyzed drying oil polyethylene glycol ester, mineral oil, phosphate ester rust inhibitor, polyether, nonionic surfactant and water to obtain a water-based metal cutting fluid.

Embodiment 1

[0045] This example discloses a method for preparing partially acidolyzed drying oil polyethylene glycol ester, which is prepared from isovaleric acid, linseed oil and polyethylene glycol 400. The preparation method includes the following steps:

[0046] A) Mix isovaleric acid and dry oil (linseed oil is used in the present invention) in a mass ratio of 1:4, add catalyst X, and catalyst X is selected from isopropyl titanate with a mass ratio of 2:1 and ultrafine The processed yellow dandelion was stirred and heated to 180°C for reaction (protected by nitrogen gas) for 180 minutes to obtain a light yellow mixed solution;

[0047] B) Mix a light yellow mixed solution and polyethylene glycol 400 at a mass ratio of 1:3, add catalyst Y, the catalyst Y is selected from benzenesulfonic acid, stir and heat to 250°C for reaction (protected by nitrogen) for 360 minutes , At the same time remove a small amount of water generated, to obtain partially acid-hydrolyzed dry oil polyethylene g...

Embodiment 2

[0049] This example provides an application example in which the partially acidified dry oil polyethylene glycol ester prepared in Example 1 is applied to the preparation of metalworking cutting fluid. The experimental formula is as follows:

[0050]

[0051] Process: Add 1 / 3 water into the beaker, slowly add partially acid-decomposed dry oil polyethylene glycol ester, polyether, 6501 and phosphate ester rust inhibitor in turn, stir evenly, then increase the stirring speed and slowly Add mineral oil for emulsification, and finally add the remaining 2 / 3 water to dilute, and obtain metal processing cutting fluid S1 after standing still.

Abstract

The invention discloses a water-based metal cutting fluid which comprises partially acidolyzed drying oil polyethylene glycol ester, mineral oil, a phosphate antirust agent, polyether, a nonionic surfactant and water. Meanwhile, the invention also discloses a preparation method of the water-based metal cutting fluid, which comprises the following steps: A) mixing isovaleric acid and drying oil, adding a catalyst X, stirring, and heating at 150-250 DEG C for reaction to obtain a faint yellow mixed solution; b) mixing the faint yellow mixed solution with polyethylene glycol 400, adding a catalyst Y, stirring, and carrying out heating reaction at 150-250 DEG C to obtain partially acidolyzed drying oil polyethylene glycol ester; and C) mixing and dispersing the partially acidolyzed drying oil polyethylene glycol ester, mineral oil, a phosphate antirust agent, polyether, a nonionic surfactant and water to obtain the water-based metal cutting fluid. The water-based metal cutting fluid aims at solving the problems that an existing cutting fluid is poor in stability and short in service cycle.

Description

technical field [0001] The invention relates to the technical field of cutting fluids, in particular to a water-based metal cutting fluid and a preparation method thereof. Background technique [0002] During the metal cutting process, the strong friction between the tool and the workpiece generates a lot of heat, which will cause oxidation and discoloration of the tool and workpiece, and affect the service life of the tool. The use of metal cutting fluid can reduce the cutting force during cutting and the friction between the tool and the workpiece, and take away the heat generated in the cutting area in time to reduce the cutting temperature and reduce tool wear, thereby increasing the service life of the tool and improving the processing efficiency, ensuring the accuracy and quality of the workpiece. Surface quality, to achieve the best economic results. [0003] Traditional metalworking cutting fluids have disadvantages such as poor stability, easy oil and soap separati...
