Abstract

The invention relates to the technical field of high-molecular compounds, in particular to graphene modified lubricating oil which comprises the following components in parts by weight: 80-90 parts of base oil, 0.5-1.2 parts of a dispersing agent, 0.8-2 parts of a defoaming agent, 0.5-1.2 parts of modified graphene and 2-4 parts of an antioxidant. According to the invention, through mechanical stirring and ultrasonic stirring, the stirring effect is better, the dispersant is added twice, the modified graphene is dispersed into the base oil, and the detergent dispersibility is good.

Description

technical field [0001] The invention relates to the technical field of polymer compounds, in particular to a graphene-modified lubricating oil. Background technique [0002] In mechanical work, the lubricating film between the friction pairs is often in a thin film lubrication state with a thickness of dozens to tens of nanometers. The lubricating film with this thickness is a nano-lubricating film. The thickness of the lubricating film is in the same order of magnitude as the surface roughness, so that the lubricating characteristics are not only determined by the viscosity of the lubricating oil, but also related to the physical and chemical properties of the lubricating oil and the friction surface characteristics. [0003] Graphene lubricants have great potential in automotive lubricants due to their superior self-healing properties, anti-wear properties and heat dissipation. [0004] However, in the existing graphene-modified lubricating oil, graphene cannot be uniform...
