Research on Preparation of Phenol-resistantheavy-duty Anticorrosive Coating for Petrochemistry

The influence of polysulfide rubber modified epoxy resin on properties of phenol-resistant heavy-duty anticorrosive coating was studied via FT-IR, SEM and immersion experiment. The influence of the functional filler on phenol-resistant properties of the coating was also studied. The results showed that the coating had good performance when taking the polysulfide rubber modified epoxy resin as the main film forming material, the glass flake as functional packing, the PVC as 3.5 and the percentage of lamellar filler as 50%. After a year of immersion in petrochemical sewage lagoon, the coating was still in good condition.
