|
摘要
针对世界第一380 m输电铁塔在临海海洋大气腐蚀环境的防腐耐候需求,设计石墨烯改性重防腐涂料体系(包括环氧石墨烯防腐底漆、环氧石墨烯阻隔中间漆和氟碳耐候面漆,其中氟碳面漆采用红白相间颜色,具有防腐和航空标识功能)对输电铁塔进行防护涂装。通过实验室配方优化、石墨烯改性重防腐涂料性能检测和示范工程涂装,最终定型涂料配方体系。同时针对临海环境室外涂装工况,介绍石墨烯改性重防腐涂料在铁塔镀锌管件的施工工艺和施工经验。
To meet the anticorrosion and weathering requirements of the world's highest 380 m transmission tower in marine atmospheric corrosive environment, graphene modified heavy-duty anticorrosive coatings(including epoxy graphene anticorrosive primer, epoxy graphene barrier intermediate paint and fluorocarbon weather-resistant top coatings) were designed and used as protective coating for transmission towers. The fluorocarbon top coatings were finished alternatively with red and white color,therewith to endow functions simultaneously in anticorrosion and aviation marking through formulation optimization and relevant performance characterization in laboratory, as well as demonstration engineering painting, the formulation and process procedure of graphene modified heavy-duty anticorrosive coatings were finally accomplished. We also introduced the construction technology and experience of graphene modified heavy-duty anticorrosive coatings for galvanized pipe at outdoor fields in marine atmospheres.
