Abstract

The invention belongs to the technical field of graphene production, and particularly discloses a graphene heavy-duty anti-corrosion wear-resistant coating and a preparation process, and the graphene heavy-duty anti-corrosion wear-resistant coating comprises the following components in parts by weight: 20-30 parts of graphene, 50-70 parts of an epoxy resin emulsion, 30-45 parts of a standard carrier solvent, 15-20 parts of silicon dioxide, 20-30 parts of deionized water, 5-10 parts of ferrotitanium powder, 5-8 parts of a surface modifier, 1-3 parts of a dispersant and 1-3 parts of barium sulfate. The standard carrier solvent can be selected from one of butyl acetate, xylene, MEK and ethyl acetate, and the surface modifier comprises a silane coupling agent, an aluminate coupling agent and a surfactant; according to the invention, the graphene is added into the epoxy resin coating, and a path for a corrosive medium to be conducted to a base material is prolonged by utilizing a labyrinth effect generated by a lamellar structure of a graphene material, so that the corrosion process is delayed, and the graphene anti-corrosion and wear-resistant coating has better anti-corrosion and wear-resistant properties.

Description

technical field [0001] The invention relates to the technical field of graphene production, in particular to a graphene heavy-duty anti-corrosion and wear-resistant coating and a preparation process. Background technique [0002] The unique properties of graphene show its great potential in the field of anticorrosion of metal materials. First, the stable sp2 hybrid structure of graphene enables it to form a physical barrier between the metal and the active medium, preventing diffusion and penetration; secondly, graphene has good thermal and chemical stability, no matter at high temperature It can remain stable even in strong corrosive environment. In addition, the good electrical and thermal conductivity of graphene contributes to the improvement of the anti-corrosion and wear-resistant properties of the coating. [0003] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, are an indispensable coating...
