Abstract: According to the orthogonal experimental design and analysis, certain amount of organic silicone, epoxy resin and related additive agents were combined with the self-made polyurethane pre-polymer, one new kind of organic silicon-epoxy resin modified polyurethane anti-corrosion coating was prepared. The basic formula of the coating was finally determined. The chemical structure and morphology of the coating were analyzed by FTIR and SEM respectively, the thermal behavior of the coating was characterized by thermo-gravimetric analysis, while a series of tests like the impact strength test, tensile strength test, water absorption test, and the acid and alkali resistance test and salt corrosion resistance test were also carried out according to the corresponding government standards. The results showed this new coating proving outstanding behaviors, may realize effective anti-corrosion performance for materials.

Key words: organic silicone, epoxy resin, polyurethane coating, anticorrosion
