The work aims to improve the corrosion resistance of anti-corrosion coatings on oil rigs and reduce the economic losses due to the failure of anti-corrosion coatings on oil rigs. The painting system of oil rigs was taken as the research object and analyzed systematically. Based on the functional analysis, causal analysis, cutting, nine-screen method, physical contradiction and other methods in TRIZ theory (Teoriya Reshenivya Izobreatatelskikh Zadatch), the paint components in the oil rig painting system were designed in an innovative manner. A total of 12 schemes were obtained, and 5 of them were selected as the optimal scheme to solve the problem through preliminary analysis. Firstly, the conjugate structure of methyl O-hydroxybenzoate was added to the polyurethane topcoat, and the p-benzoquinone free ion trapping agent was added synchronously to capture the free radicals produced by titanium dioxide molecules due to the absorption of ultraviolet rays and prevent the topcoat from aging. In addition, OTS-SiO2 superhydrophobic material was added to the topcoat to prevent microbial attachment. Then, the stainless steel scales in the epoxy intermediate paint were replaced by non-conductive glass scales. Finally, the elastic material (micrometer rubber particles) was added to the primer to solve the problem of easy peeling of the coating. The research results provide a reference for improving the corrosion resistance and environmental protection of anti-corrosion coatings.
