In this paper,the synthesis route and reaction mechanism of polybenzoxazine resin(PBZ)were summarized,and the advantages and disadvantages of PBZ prepared by solvent method,solvent-free method and suspension method were compared.Then it introduced the necessity and urgency of metal corrosion protection,the performance of PBZ and its application in the field of corrosion resistance and corrosion protection,and pointed out the shortcomings.Finally,the research progress of PBZ and corrosion-resistant PBZ composites at home and abroad was summarized.The corrosion resistance and mechanism of PBZ resin and its composites were analyzed from different molecular structure design,blending copolymerization modification and adding functional nano-fillers.Then it made a prospect for the development and application prospect of PBZ resin and its corrosion-resistant composites.This paper can provide valuable reference for the research and development of high performance polybenzoxazine resin and its composites.
