Abstract

The invention provides a graphene oxide slurry and its preparation method and application. The graphene oxide slurry is prepared after ball milling a mixture of methyl methacrylate, nitrile rubber and graphene oxide; wherein , based on the total weight of the mixture as 100%, the amount of methyl methacrylate is 84%-94%, the amount of nitrile rubber is 5%-15%, and the amount of graphene oxide is 0.1%-1%. The graphene oxide slurry provided by the invention has good dispersion stability and high interfacial compatibility, solves the problem that graphene oxide is easy to agglomerate in a solvent, and can provide a good foundation for subsequent high-quality graphene oxide functional coatings. The theoretical basis plays an important role in promoting the application of materials. In addition, the high-energy ball mill used in the preparation process of the graphene oxide slurry is a conventional general-purpose equipment with low cost, simple process, easy operation, and easy industrial production.

Description

technical field [0001] The invention relates to a graphene oxide slurry and its preparation method and application, belonging to the technical field of nano fillers. Background technique [0002] Corrosion generally refers to the interaction between materials and the environment, which makes materials lose their original properties. Corrosion of materials is reflected in all aspects of the national economy, including transportation, chemical industry, machinery, energy, etc. Metal materials may corrode under various environmental conditions, causing many equipment and precision instruments to be scrapped prematurely or even unusable. Every year, one-third of the world's scrapped steel due to corrosion can reach one-third of the total output, and about one-third of it cannot be recycled, causing economic losses as high as 1.4-2.2 trillion U.S. dollars. Corrosion will not only bring huge losses to the national economy, but catastrophic accidents such as leakage, explosion, a...
