High-temperature-resistant and corrosion-resistant phenyl-s-triazine ring-containing polyarylether coating and preparation method thereof

The invention belongs to the technical field of anti-corrosion coatings, and provides a preparation method of a high-temperature-resistant anti-corrosion phenyl-containing s-triazine ring polyarylether coating. Phenyl-containing s-triazine ring difluoro monomers, dichlorobenzonitrile and biphenol are used as raw materials; a series of polyarylether with a main chain containing phenyl-s-triazine rings are prepared through a solution nucleophilic substitution polycondensation method, a high-temperature-resistant anticorrosive coating is prepared, an organic silicon coating, an organic silicon phenolic coating and a glass fiber reinforced plastic coating are replaced, and the heat resistance and corrosion resistance of the coating are improved. The high-temperature-resistant anticorrosive coating prepared by the invention has good heat resistance and high glass-transition temperature while keeping high toughness, high adhesive force and high hardness, and is suitable for high-temperature application scenes of 50
