Abstract

Metal corrosion has spread all over all aspects of national economy and life, causing serious economic losses and ecological hazards. Because of its excellent protective effect and universality, coating has become an important choice for metal corrosion protection. Although the conventional coating can realize metal corrosion protection with its shielding effect, the protection performance gradually decreases due to mechanical damage and corrosive species erosion. Based on the actual corrosion reaction process, the concept of nanocatalytic anticorrosion is proposed in this work to realize the long-term protection for metals. Firstly, oxygen reduction catalyst was obtained by confined pyrolysis and added into epoxy resin to prepare a new nanocatalytic anticorrosion coating, and then the protective performance of the coating was studied in detail. The results show that the catalyst adopt a uniform dodecahedral structure with excellent oxygen reduction ability, the half wave potential is 0.85 V. The catalyst added in the coating can spontaneously consume the diffused oxygen in the coating while enhancing the compactness of the coating to block the corrosive medium, reduceing the contribution of the corrosive medium to the corrosion reaction. Therefore, the probability of metal corrosion can be significantly reduced, and the service life of the coating for metal protection has been greatly prolonged.
