Embodiment 2

[0025] In this embodiment, a water-soluble anti-rust cutting fluid contains the following components by weight:

[0026] 5 p-tert-butyl benzoic acid, 8 benzoic acid, 10 sebacic acid, 1 monoethanolamine, 10 triethanolamine, 1.0 benzotriazole, 5 diethylene glycol, 3 monoisopropanolamine, 15 polyethylene glycol, water 30.

[0027] According to the above parts by weight, p-tert-butylbenzoic acid, benzoic acid, sebacic acid, monoethanolamine, triethanolamine and water accounting for 50% of the total water are mixed together and reacted at a temperature of 50°C for 1 hour to obtain a mixture A; The benzotriazole of specified weight parts, one isopropanolamine and the water accounting for 50% of total water are mixed together and reacted at a temperature of 70°C for 2 hours to obtain mixture B; then mix mixture A, mixture B with diethylene glycol and poly Ethylene glycol 600 was stirred and mixed at a temperature of 60° C. for 70 minutes to obtain a finished product.

Embodiment 3

[0029] In this embodiment, a water-soluble anti-rust cutting fluid contains the following components by weight:

[0030] 15 p-tert-butyl benzoic acid, 2 benzoic acid, 1 sebacic acid, 1 monoethanolamine, 3 triethanolamine, 0.1 benzotriazole, 10 diethylene glycol, 10 monoisopropanolamine, 5 polyethylene glycol, water 20.

[0031] According to the above parts by weight, tert-butylbenzoic acid, benzoic acid, sebacic acid, monoethanolamine, triethanolamine and water accounting for 40% of the total water were mixed together and reacted at a temperature of 70°C for 3 hours to obtain a mixture A; The benzotriazole in parts by weight, one isopropanolamine and water accounting for 60% of the total water were mixed and reacted at a temperature of 90° C. for 2 hours to obtain a mixture B; then the mixture A, mixture B and diethylene glycol and poly Ethylene glycol 600 was stirred and mixed at a temperature of 70° C. for 90 minutes to obtain a finished product.

Abstract

The invention relates to a water-soluble rust prevention cutting fluid which contains the following components in parts by weight: 4.5-15.5 parts of p-tertiary butylbenzoic acid, 1.2-8.1 parts of benzoic acid, 1.5-11 parts of decanedioic acid, 0.5-5.1 parts of monoethanolamine, 2.3-10.8 parts of triethanolamine, 0.091-1.1 parts of benzotriazole, 4.5-11 parts of diethylene glycol, 2.3-10.5 parts of monoisopropanolamine, 4.5-15.5 parts of polyethylene glycol and 19-31 parts of water. the invention also relates to a preparation method of the water-soluble rust prevention cutting fluid provided by the invention, which comprises the following steps: mixing the p-tertiary butylbenzoic acid, the benzoic acid, the decanedioic acid, the monoethanolamine, the triethanolamine and part of the water, and reacting to obtain a mixture A; mixing the benzotriazole, the monoisopropanolamine and the rest of the water, and reacting to obtain a mixture B; and mixing the diethylene glycol, the polyethylene glycol, the mixture A and the mixture B, and reacting to obtain the finished product.

Description

technical field [0001] The invention relates to the technical field of cutting fluids, in particular to a water-soluble antirust cutting fluid and a preparation method thereof. Background technique [0002] Metal cutting is a widely used processing method. During the cutting process, a lot of friction and heat will be generated between the tool and the workpiece, which not only affects the processing efficiency and the quality of the workpiece, but also causes damage to the tool and equipment. Therefore, cutting fluids with good lubricating, cooling, cleaning and anti-rust properties are the goals that have been pursued in metal cutting. [0003] Cutting fluid is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, chipping and grinding. Good cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy to dilute. It overcomes the shortcomings of traditional...
