Problems solved by technology

Ordinary cutting fluids have poor anti-rust and anti-corrosion properties. After a short period of use, the oxidation reaction will cause the liquid to brown, the processing performance will decrease, and the service life will be short (increasing the cost of changing the liquid). Processed parts are severely corroded and scrapped
[0004] At present, the wire cutting fluid used in the machining industry contains toxic substances such as sodium nitrite in the formula, which is harmful to human health and environmental safety.

Embodiment 1

[0023] An environment-friendly high-dispersion permanent magnet wire-cutting fluid is a product obtained by mixing and stirring the following weight components:

[0024] Lauric acid 4%

[0025] Triisopropanolamine 30%

[0026] Alkanolamide 4%

[0027] Polyoxyethylene polyoxypropylene ether 1%

[0028] Pure water 43.7%

[0029] Dicyclohexylamine 2%

[0030] Benzotriazole 0.3%

[0031] Nonanoic Acid 15%.

[0032] In this example, macromolecular carboxylic acid lauric acid is used as a high-efficiency rust and corrosion inhibitor, which has excellent rust resistance (3.3% diluted iron filings rust prevention ≥ 120 hours) and corrosion resistance (brown iron ion content ≤10ppm), the working fluid can be used for a long time without browning, and the cycle life is long (>100 days), which not only reduces the cost of changing the fluid, but also ensures the quality of the processed parts.

Embodiment 2

[0034] An environment-friendly high-dispersion permanent magnet wire-cutting fluid consists of the following components by weight percentage:

[0035] Polymer carboxylic acid 10-30% (eg 10%, 20%, 30%)

[0036] Organic amine 20-40% (eg 20%, 30%, 40%)

[0037] New surfactant 1~20% (eg 1%, 10%, 20%)

[0038] Pure water 35-65% (eg 35%, 50%, 65%)

[0039] Preservatives or fungicides 0-5% (eg 1%, 2%, 5%).

[0040] The polymer carboxylic acid is a long-chain carboxylic acid such as caprylic acid, n-nonanoic acid, sebacic acid, adipic acid, azelaic acid, lauric acid, C8-C18 fatty acid, oleic acid, linoleic acid, triazines, etc. One or more of the carboxylic acid compounds.

[0041] The organic amine is monoethanolamine, diethanolamine, triethanolamine, monoisopropanolamine, diisopropanolamine, triisopropanolamine, morpholine, dicyclohexylamine, N-methylmorpholine, 2-amino -One or more of 2-methyl-1-propanol and diethylaminoethanol.

[0042] The surfactant is fatty alcohol polyox...

Abstract

The invention discloses an environment-friendly high-dispersivity permanent-magnet wire cutting solution which is composed of high-polymer carboxylic acid, organic amine, a novel surfactant, pure water and a preservative or bactericide. The wire cutting solution is friendly to human and environment, and has favorable operating performance.

Description

technical field [0001] The invention relates to a permanent magnet wire cutting fluid. Background technique [0002] When using the traditional free abrasive processing method, the chip powder is not easy to disperse and has poor suspension, and it is easy to adhere to the surface of the machine and tool, which affects the cutting process; at the same time, there are a large amount of solid particle waste in the working fluid, which increases the emission. [0003] Metal permanent magnet is a special processing material, the base is hard and brittle, and the surface is easily oxidized and corroded. Ordinary cutting fluids have poor anti-rust and anti-corrosion properties. After a short period of use, the oxidation reaction will cause the liquid to brown, the processing performance will decrease, and the service life will be short (increasing the cost of changing the liquid). The processed parts are severely corroded and scrapped. [0004] At present, the wire cutting fluid...
