Water-based cutting fluid stable in quality and uniform to disperse and preparation method of water-based cutting fluid

Abstract

The invention discloses a water-based cutting fluid stable in quality and uniform to disperse. The water-based cutting fluid is characterized by being prepared from the following raw materials in parts by weight: 1-2 parts of sodium molybdate, 2-3 parts of triethanolamine, 1.5-2.5 parts of carboxylic acid, 3.5-5 parts of polysorbate-80, 2-4 parts of castor oil, 4-5 parts of sodium ricinoleate, 2-3 parts of tartaric acid, 6-8 parts of nanosilicon dioxide, 2-3 parts of octadecylamine N-oleoyl sarcosinate, 5-7 parts of an auxiliary and 200 parts of deionized water. According to the water-based cutting fluid, a grinding material nanosilicon dioxide and a surfactant are mixed, so that not only is the wear resistance enhanced, but also the grinding material is uniform to disperse, thereby promoting the quality of the cutting fluid. Matched with the auxiliary, the wear resistance, dispersibility, lubricity and film-forming property of the cutting fluid are enhanced. The cutting fluid disclosed by the invention has excellent lubricating and wear resisting performance, cleaning cooling performance and anti-rust corrosion resisting performance, can avoid generation of built-up edges and effectively protects cutters and improves the processing quality. The cutting fluid is simple to operate and low in cost.

Description

technical field

[0001] The invention relates to the field of cutting fluid, in particular to a water-based cutting fluid with stable quality and uniform dispersion and a preparation method thereof. Background technique

[0002] In the machining industry, lubricating oil or Bupleurum oil plus lubricating oil is basically used for cutting lubrication and cooling. In the process of processing, oil waste is extremely serious, and it causes great harm to the environment and operators. Cutting fluids include oil-based cutting fluids containing mineral oil and additives, glycol-based cutting fluids containing polyethylene glycol or polypropylene glycol as a main component, and water-based cutting fluids in the form of aqueous surfactant solutions. The cooling effect of oil-based cutting fluid at the cutting point is poor. Oil-based cutting fluid will pollute workpieces or tools, and it needs to be cleaned with organic solvents, which is not friendly to the environment. Glycol-base...
