摘要:

研究了基于环氧微胶囊与胺类微胶囊的双组分自修复环氧树脂在自修复防腐蚀环氧涂层实际应用中所涉及的相关性能,包括自修复涂层的使用环境、自修复涂层的热稳定性、自修复涂层修复后防腐蚀性能的长效稳定性、自修复涂层自身的长效稳定性。结果表明,该自修复体系在水环境下修复时仍然具有优异的防腐蚀性能,中高温热处理(80 ℃下24 h或200 ℃下5 min)不会降低该自修复涂层的防腐蚀性能,损伤修复后自修复涂层的长效(180天)防腐蚀性能出色,同时,自修复防腐蚀涂层自身也具有较好的长效稳定性。

Abstract:

Based on the microencapsulated epoxy⁃amine chemistry self⁃healing system, the relevant properties involved in the practical application of self⁃healing anticorrosion epoxy coatings were investigated, which included the service environment, thermal stability, and long⁃term anticorrosion performance after the damage event of the self⁃healing anticorrosion coatings, as well as the long⁃term stability of the self⁃healing function for the self⁃healing anticorrosion epoxy coatings. The results indicated that the self⁃healing system exhibited excellent anticorrosion performance when healed in the water environment. The medium⁃high temperature heat treatment did not reduce the anticorrosion performance of the self⁃healing coatings at 80 ℃ for 24 h and or at 5 min for 200 ℃. The 180⁃day long⁃term anticorrosion performance of the self⁃healing coatings after damage healing is excellent. Meanwhile, the self⁃healing anticorrosion coatings have a good long⁃term stability.
