Problems solved by technology

However, there are still some defects in water-based cutting fluid: as the carrier of cutting fluid, water has low bearing capacity and poor film-forming properties, resulting in poor lubrication performance; the heat transfer coefficient of water is higher than that of oily substances, but its heat transfer performance is still relatively low. Poor, resulting in poor cooling performance of water-based cutting fluid; and the anti-rust effect of water-based cutting fluid is also worse than oil-based cutting fluid
However, the current graphene-containing water-based cutting fluids of these applications have the following problems: the current graphene cutting fluid patents usually use graphene oxide powder or do not specify the specific type and preparation method of graphene used. Oxygen-containing functional groups are introduced on the sheet, and its electrical conductivity, thermal conductivity, and lubricating properties are all reduced compared with unoxidized graphene. However, there are many methods and types of graphene preparation, and graphene powders of different types and different preparation methods There are certain differences in physical performance

Description

technical field [0001] The invention belongs to the technical field of metal cutting fluids, and in particular relates to a water-based metal cutting fluid with graphene as a lubricating, cooling and anti-rust additive and a synergistic water-based metal cutting fluid and a preparation method thereof. Background technique [0002] Metal cutting fluid is an industrial liquid used in metal cutting, grinding and other machining processes. It can not only lubricate and cool the cutting tools and workpieces, but also have the functions of antirust, cleaning and anticorrosion. It plays a key role in the complexity of metal processing technology, processing accuracy, processing quality, processing tool life, product yield, and processing economy. [0003] Metal cutting fluids are divided into water-based metal cutting fluids and oil-based metal cutting oils. Compared with oil-based cutting fluid, water-based cutting fluid has better cooling performance, lower economic cost, and mo...
