Problems solved by technology

Although the traditional fully synthetic cutting fluid has certain advantages in cleaning and heat dissipation, it has poor anti-rust and lubricating properties
Although the microemulsion cutting fluid combines the advantages of fully synthetic cutting fluid and emulsified oil, there are a lot of lipophilic and hydrophilic surfactants in the preparation process, resulting in too much foam in the diluent, which affects processing and is easy to be corroded
Although emulsified oil has excellent lubricating and anti-rust performance, its service life is short

Abstract

The invention belongs to the technical field of metal processing. More specifically, the invention relates to a fully synthetic environment-friendly cutting fluid for aluminum alloy processing and a preparation method thereof. A fully synthetic environment-friendly cutting fluid for aluminum alloy processing, comprising the following components in parts by weight: 5-25 parts of ammonium carboxylate compound antirust agent, 5-30 parts of sulfonated castor oil, 2-2 parts of water-soluble lubricant 15 parts, 1-6 parts of monobasic acid, 0.5-2 parts of anti-mold and fungicide, 0.02-1 part of defoamer, 20-55 parts of water. The invention provides a kind of fully synthetic environment-friendly cutting fluid for aluminum alloy processing, which is compounded with sulfonated castor oil and water-soluble lubricant to provide high lubricating performance. As an oil-free cutting fluid product, it can replace low oil content under the same conditions In addition, the invention protects the aluminum alloy from discoloration through the compounding of ricinoleic acid, organic acid and special alcohol amine, and solves the high lubrication requirements in the process of aluminum alloy processing.

Description

technical field [0001] The invention belongs to the technical field of metal processing. More specifically, the invention relates to a fully synthetic environment-friendly cutting fluid for aluminum alloy processing and a preparation method thereof. Background technique [0002] Cutting fluid is an important supporting material for metal cutting. It plays a good role in cooling, lubricating, cleaning and rust prevention in metal cutting. It can prolong the service life of tools, improve the surface quality of workpieces, improve processing efficiency and reduce production costs. [0003] At present, cutting fluid mainly includes fully synthetic cutting fluid, microemulsion cutting fluid, emulsified oil and so on. Although the traditional fully synthetic cutting fluid has certain advantages in cleaning and heat dissipation, its anti-rust and lubricating properties are poor. Although the microemulsion cutting fluid combines the advantages of fully synthetic cutting fluid and ...
