Problems solved by technology

[0005] However, the existing microemulsion water-soluble cutting fluid usually contains a relatively high proportion of base oil in the formula, and the oxidation and corruption of the oil will easily affect the service life of the entire product. For this reason, it is usually necessary to add a bactericide to prolong the service life. Most fungicides are irritating to the skin and harmful to the human body, and most of the fungicides are sold at a high price, resulting in high manufacturing costs for water-soluble cutting fluids

Embodiment 1

[0020] The water-soluble cutting fluid for machining includes the following components by mass percentage:

[0021]

[0022] Among them, the base oil or oily agent is mineral oil; the nonionic surfactant is polyacrylamide; the anionic surfactant is sulfate ester salt; the mixed alcohol amine is diethanolamine; the rust inhibitor is phosphoric acid; the copper alloy corrosion inhibitor is methyl Benzotriazole and its derivatives; aluminum alloy corrosion inhibitor is hexamethylenetetramine and its derivatives; defoamer is higher alcohol fatty acid ester complex.

Embodiment 2

[0024] The water-soluble cutting fluid for machining includes the following components by mass percentage:

[0025]

[0026]

[0027] Among them, the base oil or oily agent is polyol ester; the nonionic surfactant is polyoxyethylene fatty acid ester; the anionic surfactant is sulfonate; the mixed alcohol amine is triethanolamine; the rust inhibitor is dimer acid; The corrosion agent is tolutriazole and its derivatives; the aluminum alloy corrosion inhibitor is hexamethylenetetramine and its derivatives; the defoamer is polyoxyethylene polyoxypropylene pentaerythritol ether.

Embodiment 3

[0029] The water-soluble cutting fluid for machining includes the following components by mass percentage:

[0030]

[0031] The base oil or oily agent is a synthetic ester; the nonionic surfactant is polyoxyethylene fatty acid ester; the anionic surfactant is fatty acid salt; the mixed alcohol amine is monoisopropanolamine; the antirust agent is sodium citrate; The copper alloy corrosion inhibitor is tolutriazole and its derivatives; the aluminum alloy corrosion inhibitor is hexamethylenetetramine and its derivatives; the defoamer is polyoxyethylene polyoxypropylene pentaerythritol ether.

[0032] Because the water-soluble machining cutting fluid contains copper alloy corrosion inhibitor, aluminum alloy corrosion inhibitor, water softener and mixed alcohol amine, it not only has strong cooling performance, rust resistance and hard water resistance, but also is not easy to deteriorate and smell; It can have a strong inhibitory effect on fungi, bacteria, mold, etc. without a...

Abstract

The invention discloses water-soluble machining cutting fluid which comprises 6-12% of basic oil or oily agent, 2-6% of a nonionic surfactant, 5-10% of an anionic surfactant, 5-8% of mixed alcohol amine, 10-16% of an anti-rust agent, 0.08-0.1% of a copper alloy corrosion inhibitor, 0.08-0.1% of an aluminum alloy corrosion inhibitor, 0-0.5% of a water softener, 0.1-0.2% of an antifoaming agent and the balance of water. Since the water-soluble machining cutting fluid disclosed by the invention contains the copper alloy corrosion inhibitor, the aluminum alloy corrosion inhibitor, the water softener and the mixed alcohol amine, the cutting fluid is high in cooling property, anti-rust property and hard water resistance and is difficult to deteriorate and stink; and because any special bactericide is not added, the water-soluble machining cutting fluid can achieve excellent effects of inhibiting fungi, bacteria, moulds and the like. Therefore, the water-soluble machining cutting fluid has long service life and avoids irritating injury of the bactericide on skin, and the using cost of the finished product is reduced.

Description

technical field [0001] The invention relates to a cutting fluid for machining, in particular to a water-soluble cutting fluid for machining, and belongs to the technical field of cutting fluid for machining. Background technique [0002] Cutting fluid is an industrial liquid used in metal cutting and grinding to cool and lubricate cutting tools and workpieces. Cutting fluid is made of various functional additives through scientific compounding and has good cooling performance. , Lubrication performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function. [0003] Traditional cutting fluids are mostly soap-based emulsions, which have the disadvantages of being easy to stink in summer and difficult to dilute in winter. Soap-based emulsions in the prior art are gradually replaced by water-soluble cutting fluids. [0004] Water-soluble cutting fluid is a new generation of semi-synthetic microemulsion water-soluble cutting fluid prepared by scientif...
