Problems solved by technology

[0003] The water-based cutting fluid (emulsion) based on mineral oil has the best lubricity and excellent stability, but its cooling ability and cleaning ability are obviously inferior. At the same time, because of the existence of mineral oil, it cannot be emissions, which pollute the environment and cause serious harm to the health of workers
Furthermore, in the actual application of metal cutting fluid, the damage to the tool during the machining process is often caused by insufficient extreme pressure resistance, poor lubricity, anti-rust and anti-corrosion performance, resulting in a greatly shortened life span

Abstract

The invention discloses a vegetable oil-based environmentally-friendly metal cutting fluid and a preparation method thereof. The prepared metal cutting fluid has a low tapping torque value, good lubricating performances, excellent wear resistance, the anti-rust performance of A level, significantly improved dispersion performances and excellent product performances. Nano-cubic boron nitride is pretreated and the surface sites are fully activated so that the surface is rich in active groups such as hydroxyl groups for later adsorption and grafting of octadecylamine on its surface. The nano-cubic boron nitride is modified through octadecylamineso that a lot of octadecylamine long chain structures are connected to the surface through hydrogen bonds or chemical bonds and thus the compatibilityand dispersibility of nano-cubic boron nitride and vegetable oil base are improved, agglomeration and sedimentation are difficult and the performances are kept for a long time. The boron nitride-octadecylamine improves the anti-wear and anti-friction properties and anti-rust properties of the desired cutting fluid.

Description

technical field [0001] The invention belongs to the technical field of metal cutting fluid, in particular to a vegetable oil-based environment-friendly metal cutting fluid and a preparation method thereof. Background technique [0002] In the processing and manufacturing industry, metal cutting fluid is an important equipment material. It mainly plays four roles of cooling, lubrication, cleaning and rust prevention. It is used to cool tools and knives, and at the same time provide lubricating industrial liquid for knives. At present, metal cutting fluid has been widely used in all aspects of modern metal cutting processing, and has become an indispensable material in the process of machining and manufacturing. [0003] The water-based cutting fluid (emulsion) based on mineral oil has the best lubricity and excellent stability, but its cooling ability and cleaning ability are obviously inferior. At the same time, because of the existence of mineral oil, it cannot be emission...
