Problems solved by technology

[0003] Traditional hydraulic transmission systems mostly use mineral-based hydraulic oil as the working medium, which not only wastes precious oil resources, but also easily leaks, burns, and pollutes the environment. Therefore, it is not suitable for use in some special occasions, such as high temperature, open fire, underground , underwater, cabin and other working conditions

Abstract

The invention discloses a graphene-modified emulsion, which comprises mineral oil, an aqueous medium, a graphene oxide dispersion, and polysorbate-80. The emulsion is an oil-in-water emulsion, and the emulsion droplets are coated with graphene oxide, which has excellent lubrication and anti-corrosion properties, can significantly reduce material friction and wear, has a long service life, and is environmentally friendly and pollution-free. It can replace hydraulic mineral oil as a hydraulic transmission medium and is suitable for new flame retardant hydraulic transmission systems.

Description

technical field [0001] The invention relates to the technical field of emulsions, in particular to a graphene-modified emulsion, its preparation method and application. Background technique [0002] Hydraulic transmission has a series of advantages such as light weight, good rapidity, stepless speed regulation, easy overload protection, and easy control, and has been widely used in various fields of industrial production. [0003] Traditional hydraulic transmission systems mostly use mineral-based hydraulic oil as the working medium, which not only wastes precious oil resources, but also easily leaks, burns, and pollutes the environment. Therefore, it is not suitable for use in some special occasions, such as high temperature, open fire, underground , underwater, cabin and other working conditions. With the continuous enhancement of people's awareness of environmental protection, safety and sustainable development, a variety of non-petroleum-based hydraulic transmission med...
