Problems solved by technology

However, the microemulsion cutting fluid also has the following disadvantages during use: there are many foams, and a large amount of defoaming agent must be added to improve the defoaming performance, while the high-efficiency defoaming agent is expensive, has a short storage period, and is quick to fail. Supplements, which increase the cost of the product

[0011] 30 parts of glycerin and water mixture, 4 parts of trisodium phosphate, 5 parts of sodium pentachlorophenate, 5 parts of polyethylene glycol, 7 parts of sodium nitrite and 6 parts of sodium petroleum sulfonate.

Embodiment 2

[0013] The invention is a lubricating cutting fluid for metal processing, which is made of the following raw materials in parts by weight:

[0014] Glycerin and water mixture 25 parts, trisodium phosphate 3 parts, sodium pentachlorophenate 3 parts, polyethylene glycol 4 parts, sodium nitrite 4 parts and sodium petroleum sulfonate 3 parts.

Embodiment 3

[0016] The invention is a lubricating cutting fluid for metal processing, which is made of the following raw materials in parts by weight:

[0017] 35 parts of glycerin and water mixture, 7 parts of trisodium phosphate, 7 parts of sodium pentachlorophenate, 9 parts of polyethylene glycol, 9 parts of sodium nitrite and 7 parts of sodium petroleum sulfonate.

[0018] Compared with the existing cutting fluid, the present invention adopts the combination of a large proportion of anionic surfactant and a small proportion of nonionic surfactant, that is, the ratio of nonionic surfactant is greatly reduced, thereby improving the defoaming performance; the present invention adopts Adjust the content of various additives to make each component achieve synergistic effect, so that the prepared cutting fluid combines the advantages of emulsion and fully synthetic cutting fluid, and has excellent lubricity, cooling, cleaning, corrosion resistance and longer life. It has strong versatility ...

Abstract

The invention discloses a lubricant cutting fluid for metal processing. The lubricant cutting fluid is prepared from the following raw materials by weight: 25-35 parts of a mixture of glycerol and water, 3-7 parts of trisodium phosphate, 3-7 parts of sodium pentachlorophenate, 4-9 parts of polyethylene glycol, 4-9 parts of sodium nitrite and 3-7 parts of sodium petroleum sulfonate. Compared with the cutting fluid of the prior art, an anionic surfactant in a large proportion and a nonionic surfactant in a small proportion are combined to greatly reduce the ratio of the nonionic surfactant, thereby improving defoaming performance. According to the invention, the contents of additives are adjusted to reach synergism of the components, so that the prepared cutting fluid combines the advantages of an emulsion and a total synthesis cutting fluid and has excellent lubrication, cooling performance, cleaning performance, corrosion resistance and long service life.

Description

technical field [0001] The invention relates to a lubricating cutting fluid for metal processing, which belongs to the field of industrial chemical industry. Background technique [0002] According to the chemical composition of oil, cutting fluid is divided into two categories: non-water-soluble fluid and water-soluble fluid. Oil-based cutting fluids have better lubricating properties and poorer cooling effects. Compared with oil-based cutting fluid, water-based cutting fluid has relatively poor lubricating performance and better cooling effect. The emulsion combines the lubricity and antirust properties of oil with the excellent cooling properties of water, and at the same time has good lubricating and cooling properties, so it is very effective for high-speed and low-pressure metal cutting where a large amount of heat is generated. Compared with oil-based cutting fluids, the advantages of emulsions are greater heat dissipation, cleaning properties, economical benefits o...
