Abstract

The invention discloses anti-corrosion graphene coating and a preparation method thereof. The preparation method includes the steps of S1, adding dispersed graphene, a reactive diluent, a coupling agent and a dispersing agent; S2, adding epoxy resin, a curing agent, zinc powder, filler and auxiliaries while stirring; S3, using a mechanical stirrer to perform stirring, and adding zirconium beads toperform grinding; S4, sufficiently mixing the resin and the curing agent, regulating viscosity, and spraying. The anti-corrosion graphene coating proportionally comprises the graphene, the reactive diluent, the dispersing agent, the epoxy resin, the curing agent, the zinc powder, the filler, the auxiliaries and the coupling agent. The preparation method has the advantages that the method is simple in process, and the prepared anti-corrosion graphene coating is high in thermal conductivity and viscous force, stable in performance and low in price.

Description

technical field [0001] The invention relates to a graphene anticorrosion coating and a preparation method thereof. Background technique [0002] In recent years, the research on heavy-duty anti-corrosion coatings has been very rapid. On the basis of traditional conventional anti-corrosion coatings, many varieties with excellent performance have been developed, among which epoxy zinc-rich coatings are one of the products with the largest consumption. Epoxy zinc-rich coatings have The incomparable superiority of conventional anti-corrosion coatings, its main features are long anti-corrosion life, low shrinkage, strong adhesion and other properties. However, epoxy zinc-rich coatings still have some shortcomings. The residual stress of resin coatings during the curing process will cause coating cracks, and the weather resistance is poor, easy to pulverize, and poor resistance to strong corrosive media at high temperatures. [0003] Graphene zinc-rich primer is a new type of hea...
