Problems solved by technology

Generally, oil-soluble cutting fluid has good lubricating performance, but poor cooling performance, and contains a large amount of organic matter, polluting the environment
Although some water-soluble cutting fluids have good cooling performance, they also have the problem of poor lubricity and anti-rust effect. Cutting fluid that does not corrode the equipment and does not pollute the environment is very important

Embodiment Construction

[0009] A water-based metal cutting fluid, made of the following raw materials in parts by weight (kg): Polyethylene glycol 11, triethanolamine 2.5, di-n-butyl phosphite 7, castor oil 21, sulfurized alkylphenate calcium 1.5, sorbic acid Tan monostearate 1.5, auxiliary agent 7, water 200; said auxiliary agent is made of the following raw materials in parts by weight (kg): ammonium oxide 1, morpholine 2, nano-aluminum nitride 0.1, sodium silicate 1 , borax 2, 2-amino-2-methyl-1-propanol 2, polyoxyethylene sorbitan monooleate 3, peach gum 2, ammonium persulfate 1, water 20; After the ammonium is dissolved in water, add other remaining materials, stir for 10-15 minutes, heat to 70-80°C, and stir for 1-2 hours to obtain the product.

[0010] The preparation method of the water-based metal cutting fluid comprises the following steps: mixing water and sorbitan monostearate, heating to 45°C; adding polyethylene glycol, di-n-butyl phosphite, castor oil, and additives , continue heating...

Abstract

The invention discloses an aqueous cutting fluid, which is prepared from the following raw materials in parts by weight: 10-12 parts of polyethylene glycol, 2-3 parts of triethanolamine, 6-9 parts of dibutyl phosphate, 19-22 parts of castor oil, 1-2 parts of calcium sulfide alkylphenol, 1-2 parts of sorbic monostearate, 6-8 parts of assistant and 200 parts of water. The aqueous cutting fluid disclosed by the invention has excellent viscosity-temperature performance, lubricity, extreme pressure property and biodegradability, fast cooling speed, and good corrosion inhibition property, is long in service cycle in comparison with the traditional cutting fluid, small in abrasion on a tool, and high in yield, and has good protection roles on nonferrous metals and black metal, and the processed work-piece is bright.

Description

technical field [0001] The invention relates to the field of cutting fluids, in particular to a water-based metal cutting fluid and a preparation method thereof. Background technique [0002] The cutting fluid should have good cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, and easy dilution. At present, cutting fluid can be divided into two categories, oil-soluble cutting fluid and water-soluble cutting fluid. Generally, oil-soluble cutting fluid has good lubricating performance, but poor cooling performance, and contains a large amount of organic matter, which pollutes the environment. Although some water-soluble cutting fluids have good cooling performance, they also have the problem of poor lubricity and anti-rust effect. It is very important to have a cutting fluid that does not corrode the equipment and does not pollute the environment. Contents of the invention [0003] The object of ...
