摘　　要：目的研制一种室温中具备自修复性能的金属防腐涂层。方法将自制的室温固化剂DG593自修复微胶囊与酚醛环氧树脂F-51自修复微胶囊添加至金属防腐涂层中,通过探讨微胶囊含量对涂层力学性能、耐腐蚀性能、修复性能的影响,确定最优微胶囊添加量,并研究涂层在室温下自修复所需时间。结果微胶囊含量对于涂层的力学性能和修复性能具有显著影响,当质量分数为15%时,涂层具有较好的修复能力的同时,保持良好的力学性能,涂层室温自修复时间为6 h。结论自修复防腐涂层具备良好的耐腐蚀性,研究成果可以为金属自修复防腐涂料的发展提供参考。Objective To prepare a metal anti-corrosion coating with self-healing property at room temperature. Methods Self-healing microcapsules of Phenol-formaldehyde resin F-51 and Self-healing microcapsules of room temperature curing agent DG593 were added to the metal anti-corrosion coating. Influences of microcapsule content on mechanical property, corrosion resistance and fixing performance of coating were discussed to determine the best additive amount of microcapsules and research the time required for self-healing of coating at room temperature. Results The content of microcapsules had significant impact on mechanical property and repairing property of coating. When the mass fraction was 15%, the coating had good repairing property and could keep good mechanical property. The time for self-healing of coating at room temperature was 6 hours Conclusion The self-healing anticorrosive coating has good corrosion resistance. The research results can provide a reference for the development of metal self-healing coating.
