preparation example Construction

[0039] The preparation methods of graphene include mechanical exfoliation method, epitaxial growth method, chemical vapor deposition method, chemical synthesis method, graphene oxide reduction method and longitudinal cutting carbon tube method. In this application, the graphene oxide is commercially available and purchased from Suzhou Hengqiu Graphene Co., Ltd.

[0040] As a preferred technical solution of the present invention, the graphene is layered graphene oxide.

[0041] The term "graphene oxide" means that graphene treated with a strong oxidant contains three elements, C, H, and O. Graphene oxide is stacked layer by layer through interlayer hydrogen bonds and other forces.

[0042] The three commonly used methods for preparing graphene oxide, namely Brodie method, Staudenmaier method and Hummers method, all use strong acid to strengthen the combination of oxidizing agents to treat graphite. A strong protonic acid enters the graphite interlayer to form a graphite inter...

Description

technical field [0001] The invention relates to the technical field of lubricating oil additives, in particular to a graphene composite lubricating oil additive and a preparation method thereof. Background technique [0002] Lubricating oil additives are an important factor determining the performance and service time of lubricating oil. From the 1930s to the present, there are many types of lubricating oil additives. From the perspective of function, they are mainly divided into two categories. One is to improve the physical properties of lubricating oil. There are viscosity index improvers, oily agents, pour point depressants and antifoaming agents, which can deform, absorb and solubilize lubricating oil molecules; the other is to improve the chemical properties of lubricating oils, such as extreme pressure antiwear agents, antioxidant Anti-corrosion agents, anti-rust agents, ashless dispersants and detergent dispersants, which themselves chemically react with lubricating ...
