AI Technical Summary

Technical Problem

The existing multi-coating protection system for offshore wind power facilities is susceptible to water vapor erosion in the marine environment, which leads to a decrease in bonding strength and affects the long-term stability and protective effect of the system.

Method used

A latent reactive conductive primer slurry is used. By adjusting the ratio of bisphenol A epoxy resin to modified polyamide curing agent, a semi-cured primer layer is formed. Electrophoretic penetration technology is used to drive waterborne polyetheramine and tetrabutylammonium bromide to penetrate into the primer network in an acidic electrolyte, promoting chemical bonding reaction and constructing a chemically bonded gradient interpenetrating network structure.

Benefits of technology

It improves the interfacial bonding strength and hydrolytic stability between coatings, enhances the adhesion of the protective layer, effectively prevents water vapor penetration and the spread of corrosive media, and improves the overall shielding performance and long-term protection performance of the protective layer under damaged conditions.
