TRIZ理论在提高石油钻井平台涂料耐腐蚀性方面的应用

目的 提高石油钻井平台防腐涂料的耐腐蚀性，减少由于石油钻井平台防腐涂层失效造成的经济损失。方法 本文以石油钻井平台漆装系统为研究对象对其进行系统分析，并基于TRIZ理论(Teoriya Reshenivya Izobreatatelskikh Zadatch, TRIZ, 译为发明问题解决理论)中的功能分析、因果分析、裁剪、九屏幕法、物理矛盾等工具对石油钻井平台漆装系统中涂料的组成成分进行创新设计。结果 本文共得到了12个方案，通过初步分析选用了其中的5个方案构成解决问题的最优方案:首先在聚氨酯面漆中加入共轭结构的邻羟基苯甲酸甲酯，同时加入对苯醌自由离子捕捉剂，捕捉二氧化钛分子因吸收紫外线产生的自由基，防止面漆老化。此外还在面漆中加入OTS-SiO2超疏水材料，阻止微生物附着。然后将环氧树脂中间漆中的不锈钢鳞片由不导电的玻璃鳞片替换。最后在底漆中加入弹性材料(微米级橡胶粒子)，改善涂层易剥落的问题。结论 该研究成果为提高防腐涂料的耐蚀性和环保性提供了参考。

Application of TRIZ Theory to Improve the Corrosion Resistance of Oil Rig Coatings

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.
