Abstract
The invention provides a antistatic paint for a steel structure surface and a preparation method thereof. The paint is prepared by mixing zinc-aluminum alloy powder slurry and ethyl orthosilicate slurry in a mass ratio of 3:1-5:1. The ethyl orthosilicate in the ethyl orthosilicate slurry is subjected to hydrolytic condensation under the action of a catalyst, and a furfural-furfuryl alcohol resin is added as a modifier into the zinc-aluminum alloy powder slurry. After the zinc-aluminum alloy powder slurry and ethyl orthosilicate slurry are mixed, the furfural-furfuryl alcohol resin is cured to release water molecules when meeting with acid so as to promote the further condensation of the ethyl orthosilicate hydrolytic condensation substances, and the furfural-furfuryl alcohol resin and the zinc-aluminum alloy powder react to form a interpenetrating network, thereby enhancing the crosslinking density between the paint and the steel structure substrate surface and increasing the wettability and adhesive force of the coating for the substrate.Preferably, a carbon nanotube dispersion solution and conductive mica powder can be added into the zinc-aluminum alloy powder slurry to correspondingly improve the antistatic property of the obtained coating. Therefore, the protective paint is suitable for various steel storage tank internal and external walls, large bridges, ships, offshore oil drilling platforms and other steel structure surfaces.
