However, in the actual use of existing carbon nanotube anti-corrosion coatings, due to the large aspect ratio and specific surface area of ​​carbon nanotubes, the coatings It is easy to agglomerate between them, which not only affects the use, but also is not conducive to storage, and its own heat resistance is poor, which needs to be improved

[0003] Chinese Patent No. CN106675317A discloses a carbon nanotube modified conductive anti-corrosion coating for grounding grids, which is mainly aimed at the problem that the existing conductive coating has poor corrosion resistance, and the anti-corrosion coating with better corrosion resistance has low electrical conductivity. , using nano-carbon powder filler, epoxy resin matrix, nano-magnetic iron oxide, inert diluent, polyurethane resin, alkyd resin, polyvinyl alcohol, ethyl acetate, dispersant, acetone, methyl isobutyl ketone and triphosphate The ratio between butyl ester and other materials can realize the conductivity of carbon nanotube anticorrosive coatings, but the influence of the agglomeration of carbon nanotube anticorrosive coatings on the use of coatings is still ignored, and needs to be improved

[0004] Chinese Patent No. CN112574606A discloses a carbon nanotube anti-corrosion coating. Compared with the prior art, the invention has the advantages of environmentally friendly materials and environmentally friendly production process. The resulting paint film has excellent water resistance and anti-corrosion performance, and has high bonding strength. Alkali resistance and corrosion resistance are excellent, which greatly improves the scope of application and cost performance of the coating. Although the bonding strength of the carbon nanotube anti-corrosion coating has been improved, the problem of agglomeration and storage of the coating cannot be solved. make improvements
