Abstract
The invention provides a metal cutting fluid and application thereof, belonging to the technical field of metal cutting fluids. The metal cutting fluid comprises the following components: 10-15 parts of phosphate, 5-7 parts of potassium carbonate, 0.02-0.07 part of ethylene diamine tetraacetic acid, 2-4 parts of C14 alcohol polyoxyethylene (3) ether, 0.2-0.7 part of benzotriazole, 0.3-0.8 part of ethylene glycol dimethyl ether, 0.2-0.7 part of ethylene glycol dimethyl ether and 60-80 parts of water; the phosphate ester comprises one or more of oleyl alcohol polyoxyethylene (3) ether phosphate, arachidyl alcohol polyoxyethylene (4) ether phosphate and stearyl alcohol polyoxyethylene (4) ether phosphate. The metal cutting fluid has the advantages of high lubricity and good antirust performance.
Description
Technical Field
The invention belongs to the technical field of metal cutting fluid, and particularly relates to metal cutting fluid and application thereof.
Background
The metal cutting fluid is essential in the metal processing process and is widely applied to industries such as 3C, automobile, aerospace, machining and the like. The metal processing process can be divided into four categories of cutting, forming, protecting and heat treatment according to the treatment mode. The metal cutting fluid is widely applied to various metal cutting processing technologies, such as turning, grinding, milling and the like, and has the functions of lubrication, cooling, rust prevention, cleaning and the like in the processing process.
Currently, metal cutting fluids are mainly classified into oil-based cutting fluids and water-based cutting fluids. The oil-based cutting fluid has the advantages of great environmental pollution, flammability and slow cooling in the using process, and organic matters are needed in the cleaning process, thus causing serious harm to human bodies; compared with oil-based cutting fluid, the water-based cutting fluid has excellent cooling and cleaning performances, low cost and no pollution, but the lubricating performance and the antirust performance of the water-based cutting fluid are unsatisfactory.
Disclosure of Invention
In view of the above-mentioned drawbacks, the present invention provides a metal cutting fluid having high lubricity and excellent rust prevention properties.
The purpose of the invention is realized by adopting the following technical scheme:
a metal cutting fluid comprises the following components: 10-15 parts of phosphate, 5-7 parts of potassium carbonate, 0.02-0.07 part of ethylenediamine tetraacetic acid, 2-4 parts of C14 alcohol polyoxyethylene (3) ether, 0.2-0.7 part of benzotriazole, 0.3-0.8 part of glycol dimethyl ether, 0.2-0.7 part of glycol dimethyl ether and 60-80 parts of water;
the phosphate comprises one or more of oleyl alcohol polyoxyethylene (3) ether phosphate, arachidyl alcohol polyoxyethylene (4) ether phosphate and stearyl alcohol polyoxyethylene (4) ether phosphate.
