Lubricant for metal working

Abstract

The invention discloses a lubricant for metal working, which is prepared from the following raw materials in parts by weight: 5-8 parts of methyl nonylphenol ether phosphate ethanolamine salt, 2-7 parts of trifluoromethyl epoxyethane, 25-35 parts of vegetable blended oil, 4-8 parts of epoxyethane, 2-7 parts of benzoic acid and 4-7 parts of oleic acid glycol ester. Compared with the existing lubricant, the combination of the high-ratio anionic surfactant and low-ratio nonionic surfactant greatly lowers the ratio of the nonionic surfactant, thereby enhancing the defoaming performance; and by regulating the contents of various additives, the components achieve the synergetic effect, so that the prepared lubricant integrates the advantages of the emulsion and complete synthesis lubricant, and has the advantages of excellent lubricating property, excellent cooling property, excellent cleaning performance, excellent corrosion resistance and longer service life.

Description

technical field [0001] The invention relates to a lubricant for metal processing, which belongs to the field of industrial chemical industry. Background technique [0002] Lubricants are divided into two categories according to the chemical composition of the oil: non-water-soluble liquid and water-soluble liquid. Oil-based lubricants have better lubricating properties and poorer cooling effects. Compared with oil-based lubricants, water-based lubricants have relatively poor lubricating properties and better cooling effects. 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 lubricants, the advantages of emulsions are greater heat dissipation, cleanability, economical benefits of diluting with water, and health...

Problems solved by technology

But the microemulsion lubricant also has the following disadvantages in the use process: there are many foams, and a large amount of defoamer will be added to improve the defoaming performance, while the high-efficiency defoamer is expensive, has a short storage period, and is quick to fail.
