Abstract

In order to solve the defects in the prior art, the invention provides graphene water-borne epoxy wear-resistant self-leveling paint, which is prepared by the following method with the steps of S1, sequentially adding epoxy resin, deionized water, dispersing agents, anti-foaming agents, wetting agents and filling materials into a reaction kettle; performing mixing; adding graphene materials in thestirring process, wherein the addition time of the graphene materials is 20 to 50 min; performing stirring to uniform disperse; then, performing filtering; after the filtering is completed, taking filter liquid to obtain a mixed solution; S2, sequentially adding curing agents, anti-foaming agents and leveling agents into the obtained mixed solution; performing stirring for 0.5 to 2h to obtain thegraphene water-borne epoxy wear-resistant self-leveling paint. The epoxy resin is the ingredient A; other substances are the ingredient B; the mass ratio of the ingredient A to the ingredient B is 1:(3 to 5). The graphene paint has high-wear-resistant durability, is safe and achieves the environment-friendly effects, and is non-toxic and odorless, VOC emission is avoided, achieves green and environment-friendly effects, does not contain heavy metal, and has the excellent performance of non-combustible performance, non-explosiveness and the like.

Description

technical field [0001] The invention belongs to the technical field of functional coatings, in particular to a graphene electromagnetic shielding coating and a preparation method thereof. Background technique [0002] With the development of modern science and technology, artificial satellites, spacecraft, high-speed trains, impellers of steam turbines and engines, propellers of ships, blades of hydroelectric generators, decks of ships, floors of buildings, road marking paint, etc. The high-speed airflow, the erosion of sand and water, and the action of mechanical force, the wear of the material is quite serious.
