摘　　要：为了优选高效可靠的防锈涂料用于钢结构工业遗存设备的保护,以浙江巨化电石有限公司工业遗址修缮保护项目中受腐蚀严重的钢结构设备单体为保护对象,进行针对工业生产环境下钢结构工业遗存设备的防锈涂料适用性研究。首先,筛选以环氧富锌防锈漆、红丹防锈漆和石墨烯富锌防锈漆等为底漆的3类防锈涂料开展防锈保护试验,采用酸碱加速腐蚀法对钢板和防锈涂层进行加速腐蚀处理;其次通过测量涂层老化过程中的质量损失、腐蚀电位与电化学阻抗谱,观测涂层表面微观形貌变化和测试现场涂层附着力等研究方法分析防锈保护效果;最后完成对各防锈涂层的保护性能评价。结果显示,环氧富锌漆作为底漆的防锈涂层在腐蚀电位、涂层电阻测量、表面微观观察及现场附着力测试中均获得最佳效果;从涂层电阻下降速度来看,石墨烯富锌漆作为底漆的防锈涂层电阻下降速度最慢,耐久性能更佳;红丹漆作为底漆的防锈涂层在测试中防锈效果较不理想。本研究方法及测试结果可以为今后钢结构工业遗址保护设计中防锈涂料的选用提供参考。To optimize the efficient and reliable anticorrosive coating for the protection of industrial heritage equipment of steel structure,severely corroded steel structure equipment in the renovation and protection project of the industrialsites of Quzhou Juhua Calcium Carbide Factory in Zhejiang was selected as the protected object for conducting the applicability study of anticorrosive coating for industrial heritage equipment of steel structure in industrial production environment.Three kinds of anticorrosive coating were screened,namely epoxy zinc-rich primer,red lead primer and graphene zinc-rich primer as the primer coating to carry out anticorrosive tests.Firstly,accelerated corrosion treatment of steel plate and anticorrosive coating was performed with the acid and alkali accelerated corrosion method.Secondly,the anticorrosive protection effect was analyzed by measuring mass loss,corrosion potential and electrochemical impedance spectrum during the aging process of the coating,observing the change in microscopic morphology on coating surface,and testing the coating adhesion on site.Finally,evaluation was completed with regard to the protection performance of each anticorrosive coating.The results show that the anticorrosive coating with epoxy zinc-rich primer achieves the best results in corrosion potential,coating resistance measurement,surface microscopic observation and on-site adhesion test.In terms of the coating resistance decline rate,the anticorrosive coating with graphene zinc-rich primer has the slowest decline rate resistance and better durability,while the anticorrosive coating with red lead primer has unsatisfactory anticorrosive effect.The research methods and test results can provide reference for testing and selection of anticorrosive coatings in the protection design of steel structure industrial heritage in the future.
