Abstract

The invention relates to graphene-based nano zero-valent cobalt-iron-copper lubricating oil. The lubricating oil comprises the following components: base oil, graphene-based nanoparticles, an antioxidant, a viscosity index-reducing improver, a dispersant and an anti-foaming agent, as well as other additives, wherein other additives comprise one or more of an anti-rust agent, a pour point depressant, a viscosity increaser, a detergent and a demulsifier, wherein the graphene-based nanoparticles certainly contain three substances, namely graphene-based nano zero-valent cobalt, graphene-based nano zero-valent iron and graphene-based nano zero-valent copper. The lubricating oil provided by the invention can improve conditions of the lubricating oil; and furthermore, all the components have excellent dispersivity and stability, so that excellent friction reduction and wear resistance effects can be realized, and the lubricating oil further has a good self-repair function.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a graphene-based nano zero-valent cobalt-iron-copper lubricating oil and a preparation method thereof, belonging to the field of high-tech materials and their applications. Background technique [0002] For mechanical parts, friction and wear are inevitable, which not only brings a large loss of materials and energy, but also causes environmental pollution. Lubricating oil is one of the important technical means to effectively slow down the friction and wear of mechanical parts and reduce energy loss. Lubricating oil is the blood of modern industry and national defense industry. It is composed of base oil and additives. The rapid development of modern industry requires the upgrading of lubricating oil. Generally, there are three ways to improve oil quality: 1) Improve the quality of base oil, 2) Improve the performance of additives, 3) Improve the compounding technology of additives. Lubric...
