Cutting fluid and preparation method thereof

Abstract

The invention discloses a cutting fluid and a preparation method thereof. The preparation method comprises the steps of mixing trimethylolpropane fatty acid ester, ternary polycarboxylate, sebacic acid, triethanolamine, guerbet alcohol, ethylene oxide cyclohexylamine and benzotriazole at the ratio, adding to water, stirring evenly, heating, reacting for a certain period of time to form a transparent solution and a solid without particles and preparing a water-soluble cutting fluid complex agent; and adding fatty alcohol-polyoxyethylene ether and starcide BK into the water-soluble cutting fluid complex agent, stirring at a uniform sped at room temperature for a certain period of time until the solution is transparent, adding graphene oxide, further stirring at a uniform sped at the room temperature till the solution is semitransparent, thus obtaining the cutting fluid containing the graphene oxide. The cutting fluid is green, environment-friendly and pollution-free in components and good in lubricating property.

Description

technical field [0001] The invention relates to the field of metal cutting fluid, in particular to a cutting fluid and a preparation method thereof. Background technique [0002] Cutting fluid is a liquid used for lubricating and cooling the surface of the workpiece during the machining of metal workpieces by machine tools, which can ensure the accuracy and smoothness of the surface of the workpiece and prolong the service life of the cutting tool. Metal cutting fluids are divided into oil-based and water-based, and now most of them are non-oily cutting fluids with water as the dispersion medium. These cutting fluids use water as the main component and contain lubricants, antioxidants, rust inhibitors, etc. It has the cooling, lubricating, cleaning and other properties required for metal cold processing. Additives in cutting fluids have certain pollution to the environment. For example, cutting fluids containing short-chain chlorinated paraffin extreme pressure agents may p...

AI Technical Summary

Problems solved by technology

Additives in cutting fluids have certain pollution to the environment. For example, cutting fluids containing short-chain chlorinated paraffin extreme pressure agents may produce strong carcinogenic dioxins during incineration. Phenol has poor biodegradability and has great effects on aquatic organisms. The accumulation of phosphate will lead to eutrophication of water quality and cause red tide. Sodium nitrite has good antirust performance, but it is a potential carcinogen
