Abstract

The invention discloses an aqueous environment-friendly cutting fluid synergized by a functional ionic liquid and a method for preparing the same. The method comprises the following steps: stirring and mixing a synthetic ester, a vegetable oil and an antiseptic uniformly under normal pressure and temperature to obtain a mixture A; stirring and mixing a PH stabilizer, an antirust agent and water at 30-80 DEG C for 10 minutes to 1 hour to obtain a mixture B; stirring and mixing an emulsifier and an ionic liquid extreme-pressure agent under normal pressure and temperature to obtain a mixture C; adding the mixture A, the mixture B and the mixture C into a reactor, adding a copper corrosion inhibitor and an aluminum corrosion inhibitor, and stirring and mixing at 30-80 DEG C for 10 minutes to 1 hour to obtain the product. The extreme-pressure agent has excellent abrasion resistance and can be subjected to chemical reaction with the metal surface to produce a passivation film so as to protect the metal surface. In addition, the ionic liquid compound comprises a variety of anions and cations so that the system has the advantages of special bactericidal performance, lubricating performance, cooling performance and chemical stability which are not owned by the common antiseptic.

Description

technical field [0001] The present invention relates to a water-based environment-friendly cutting fluid, more precisely, relates to a functional ionic liquid-enhanced water-based cutting fluid, belonging to the field of metalworking fluids, and the invention also relates to a water-based environment-friendly ionic liquid-assisted synergistic Preparation method of cutting fluid. Background technique [0002] Glycerin trioleate is used as emulsifier, emulsion stabilizer and wetting agent in food and cosmetics. In the field of lubrication, due to the shortage of global petrochemical resources and the pollution of the ecological environment, as well as the excellent lubricating and antirust properties of triolein itself, the demand for it as an environmentally friendly oil will increase. Although triglyceride has been widely used in industry, most of it is extracted from natural animal and vegetable oils, which not only has high cost and pollutes the environment, but also make...
