Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a graphene dispersion method for a graphene-based anticorrosive coating.
Background
Corrosion is the material destruction caused by the reaction of the material with the environment and is the main cause of the failure of the metal material, and is a problem facing the world. It is estimated that 30% of the total plant production due to corrosion in metal plants scrapped annually worldwide can be slowed or avoided in significant losses.
Graphene, a novel carbon material, has received much attention from the scientific community because of its large specific surface area, high thermal conductivity, low electrical resistivity, impermeability, and the like. The graphene is dispersedly added into the organic coating to obtain the anticorrosive coating, and the anticorrosive coating combines the cohesiveness, flexibility and processability of the organic coating and the barrier property, mechanical property, heat resistance and chemical stability of the two-dimensional nano material, and is considered to be the most concise corrosion protection coating with the application prospect. The graphene is uniformly dispersed in the coating, a compact physical shielding layer is formed, the diffusion path of a corrosive medium is prolonged, the diffusion rate of a corrosion factor is greatly reduced, and the diffusion of silver streaks when the coating is interfered by the outside can be effectively prevented. In addition, micropores can be left in the process of curing and film-forming the organic coating, corrosion factors can invade the metal matrix through the micropores, and graphene can be used as a filler to block the micropores so as to play an excellent corrosion protection role. However, due to the strong interaction between graphene sheets, graphene is directly added into resin, and is very easy to agglomerate, even more micropores are generated, and the corrosion resistance is seriously affected. Therefore, promoting effective dispersion of graphene is a key to the application of graphene in coatings.
