Abstract：To address the por anti-corrosion performance of spatial connectors in assembled metro stations ，epoxy resin E51 was used as the film-forming material，cuprous oxide （ Cu2O ）and ammonium polyphosphate（APP）as flame retardants，and graphene（Gr），hydrotalcite（HT），and nano-silicon dioxide（ SiO2 ）as anti-corrosion fillers to prepare three types ofEPcomposite coatings with anti-corrosion properties for theconnectors’anti-corrosion protection.The three coatings were 0.5% Gr-EP flame-retardant and anti-corrosion composite coating（by mass fraction）， 1.0% HT-EP flame-retardant and anti-corrosion composite coating（by mass fraction），and 1.0% SiO2 - EPflame-retardant and anti-corrosion composite coating（by mass fraction）.Performance tests were conducted on these three coatings，and their application effects were analyzed.The results showed that the addition of anti-corrosionfillrs could effectively improve the water resistance and corosion resistance of the EPflame-retardant composite coatings，among which the 1.0% SiO2-EP flame-retardant and anti-corrosion composite coating exhibited the best water and corrosion resistance.
