The anticorrosive coatings prepared in the first to third examples were tested for adhesion, salt water resistance and neutral salt spray resistance, and the test results are shown in table 1. Wherein the adhesion is tested according to GB/T9286-1998; the neutral salt spray resistance test is carried out according to GB/T1771-1991; the salt water resistance is measured according to a normal-temperature salt water resistance method in GB/T1763-89, the concentration of sodium chloride is 3%, and the phenomena of peeling, wrinkling, bubbling, rusting, discoloration and the like of a paint film are observed after the paint sample is soaked for 30 days. The waterproof coatings prepared in the first to third examples were subjected to a water impermeability test under a water pressure of 0.3MPa for 30min, and the water permeability was observed, and the test results are shown in table 1.
