Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a corrosion-resistant modified polysulfone coating. Background technique [0002] Corrosion problems will cause a lot of waste of resources and energy, pollute the environment, and more seriously, cause personal injury and death. Polysulfone is a thermoplastic resin. Its molecular chain contains sulfone groups, benzene rings and other groups. It has good mechanical properties, thermal stability, oxidation resistance, acid and alkali resistance, creep resistance, and low cost. Advantages, has been used in electrical and electronic, food and daily necessities, automobiles, aviation, medical and general industries and other fields. With the advancement of technology and the diversification of corrosion problems, people have put forward more requirements for the variety and performance of anti-corrosion coatings. The corrosion resistance and aging resistance of the existing polysu...
