摘要: 

本文聚焦储罐内顶板、底板、罐壁及加热盘管等关键部位,系统分析了各部位对涂层的性能要求,包括热稳定性、抗腐蚀性以及机械性能等,同时需兼顾响应性能。深入探讨本征型、外援型自修复涂层在原油储罐内应用的优缺点及适用性,发现pH与离子双响应微容器因自修复效率高、抗腐蚀性与耐热性佳、响应性好且成本低更具优势,但需优化微胶囊分散与兼容问题。未来需围绕材料配方、制备工艺等进行优化,以推动自修复涂层在原油储罐防护中的应用,保障行业安全与可持续发展。

关键词 原油储罐自修复涂层适应性    
Abstract

The internal environment of crude oil storage tanks remains complex and harsh over extended periods, leading to frequent failure of conventional protective coatings. As an innovative intelligent protective material, self-healing coatings demonstrate significant application potential for corrosion protection in crude oil storage tanks. This study examines key tank components—including the inner roof, bottom plate, tank wall, and heating coils, and systematically analyzes the performance requirements for coatings in each area, encompassing thermal stability, corrosion resistance, mechanical properties, as well as responsive performance. The paper provides an in-depth evaluation of the advantages, limitations, and applicability of self-healing coatings (both intrinsic and extrinsic) for crude oil storage tank applications. Findings indicate that pH- and ion dual-responsive microcontainers offer superior advantages due to their high self-healing efficiency, excellent corrosion resistance, good thermal stability, strong responsiveness, and cost-effectiveness. However, challenges regarding microcapsule dispersion and matrix compatibility require further optimization.
