Problems solved by technology

[0004] Cutting fluid is essential in metal processing. At present, compared with oil-based cutting fluid, water-based cutting fluid has excellent cooling and cleaning performance, and is lower in cost and pollution-free, which meets the social requirements of sustainable development. However, the lubricating performance is poor, so the scope of application is limited
Some organic compounds containing S, P, Cl and other elements, although they have certain good effects, will seriously pollute the external environment and working environment

Abstract

The invention relates to a metal cutting fluid containing a graphene dispersion solution and a preparation method thereof. The metal cutting fluid is composed of the following raw materials: 0.2-2.0% of lubricating additive, 5-7% of rust inhibitor, 0.2-0.5% of corrosion inhibitor, 0.05-0.15% of hard water resisting agent, 15-20% of lubricant and the balance of water. The lubricating additive is the graphene dispersion solution. The metal cutting fluid has favorable lubricating property and antirust property; by using the water base as the carrier, the metal cutting fluid is free of base oil; and the production process has the advantages of low energy consumption and low production cost, and is simple to operate.

Description

technical field [0001] The invention relates to the field of metal cutting lubrication, in particular to a metal cutting fluid containing a graphene dispersion and a preparation method thereof. Background technique [0002] Graphene is a single-layer graphite sheet with a thickness of only 0.335nm. It is a 2D honeycomb crystal structure formed by carbon atoms. In 2004, Geim and Novoselov, scientists at the University of Manchester in the United Kingdom, collaborated to prepare a two-dimensional graphene material that can exist independently for the first time, and won the 2010 Nobel Prize in Physics. Since then, the peculiar electrical, mechanical, optical and tribological properties of graphene have been gradually discovered by scientists. Graphene is a zero-bandgap semiconductor. The hardness and strength of graphene are the highest among known materials. It is harder than diamond and 100 times stronger than the best steel in the world. At the same time, graphene also ex...
