Embodiment 1

[0025] In the stirred tank, according to the mass percentage, according to the following composition ratio:

[0026] Corrosion inhibitor: 5%; lubricant and cleaning agent: 4%; rust inhibitor: 10%; chelating agent: 2%; dispersant: 2%; antibacterial agent: 1%; water: the balance. After adding, fully stir to turn into a transparent liquid, and adjust the pH value of the proportioned solution to 7, which can be packaged and used. The ratio of the prepared solution to water is 1:10 by volume.

[0027] In this example, the corrosion inhibitor is selected from a mixture of pyridinium salt and benzotriazole with a mass ratio of 1:1. The lubricant and the cleaning agent are selected from one kind of substances, which simultaneously function as the lubricant and the cleaning agent, and are selected from sodium dodecylbenzene sulfonate; and the antirust agent is selected from carbonates. The chelating agent is selected from sodium tripolyphosphate. Dispersants are selected from polyet...

Embodiment 2

[0029] In the stirred tank, according to the mass percentage, according to the following composition ratio: corrosion inhibitor: 10%; lubricant and cleaning agent: 7%; rust inhibitor: 15%; chelating agent: 1%; dispersant: 5%; Antibacterial agent: 5%; water: balance. After adding, fully stir to turn into a transparent liquid, and adjust the pH value of the proportioned solution to 9, which can be packaged and used. The ratio of the formulated solution to water is 1:20 by volume. In this example, the corrosion inhibitor is a mixture of pyridinium salt and benzotriazole in a mass ratio of 1:1.

[0030] The above-mentioned lubricant and cleaning agent are selected from Taikoo oil; the antirust agent is selected from borate. The chelating agent is selected from disodium edetate. The dispersant is selected from glycerin. The antibacterial agent is selected from ethylparaben.

Embodiment 3

[0032] According to the following composition ratio: according to mass percentage,

[0033] Corrosion inhibitor: 8%; lubricant and cleaning agent: 10%; rust inhibitor: 13%; chelating agent: 1.5%; dispersant: 4%; antibacterial agent: 3%; water: the balance. After adding, fully stir to turn into a transparent liquid, and adjust the pH value of the proportioned solution to 8, which can be packaged and used. The ratio of the formulated solution to water is 1:15 by volume. In this example, the corrosion inhibitor is a mixture of pyridinium salt and benzotriazole in a mass ratio of 1:1. Lubricant and cleaning agent are added flatly.

[0034] The antirust agent is selected from a mixture of tungstate and borate, and the ratio of the mixture is not limited. The chelating agent is selected from a mixture of sodium tripolyphosphate and disodium edetate, and the ratio is not limited. The dispersant is a mixture of polyethylene glycol and glycerin, and the ratio is not limited. The a...

Abstract

The invention relates to a cutting fluid for metal processing, and particularly relates to a multifunctional long-acting transparent water-based metal cutting fluid. The cutting fluid comprises the following components by mass percent: 5-10% of corrosion inhibitor, 4-10% of lubricant and cleaning agent, 10-15% of antirust agent, 1-2% of chelating agent, 2-5% of dispersing agent, 1-5% of antibacterial agent, and the balance of water. The water-based metal cutting fluid has good lubrication and cooling effect; the rust-proof life is long, and after workpieces are processed, the rust-proof life is 2-3 times that of the workpieces processed by saponified oil; the metal cutting fluid has good antibacterial property, is not easy to mildew, can be used for as long as ten days, and obviously lowers the cost; the metal cutting fluid has good cleaning performance and anti-foaming property, and the surface of the workpiece is clean and smooth; the metal cutting fluid is safe, has no toxicity or peculiar smell, does not contain additives such as sodium nitrite, sulphur, chlorine and phenol, does not irritate skin, does not contaminate the environment, is environment-friendly, greatly improves processing accuracy, and prolongs the service life of cutters.

Description

technical field [0001] The invention relates to a metal processing cutting fluid, in particular to a transparent multifunctional long-acting water-based metal cutting fluid. Background technique [0002] Cutting fluid (coolant) is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, chipping and grinding. [0003] The history of human use of cutting fluid can be traced back to ancient times. Watering was known to improve efficiency and quality when grinding stone, copper, and iron tools. Olive oil was used in turning piston pump castings in ancient Rome, and tallow and water solvents were used in the 16th century to polish metal armor. After a long development in 1860, various machine tools such as turning, milling, planing, grinding, gear processing and thread processing appeared one after another, which also marked the beginning of large-scale application of cutting fluid. [0004] Faced with the increasingly mature developm...
