【摘要】：石墨烯是一种新型二维层状结构的碳材料,具有高长径比、优异的阻隔水汽、导电、导热和化学稳定性能,使其在重防腐涂料领域具有广泛的市场应用前景。目前国家电网输电铁塔基材主要采用碳钢基底,表面通过镀锌对基材进行防护,取得良好防腐效果。近年来随着大气污染加重,特别是工业大气腐蚀区和沿海海洋大气腐蚀区,由于酸雨(主要成分是氮氧化物和硫氧化物)和腐蚀性氯离子的耦合作用,镀锌层腐蚀失效和脱落严重,甚至出现腐蚀穿孔现象,严重影响国家电网安全稳定输电。主要介绍中国科学院海洋新材料与应用技术重点实验室功能涂料研究团队在石墨烯基重防腐涂料的防腐机理与现场示范工程应用,并分享了涂料开发与施工经验。王立平研究员领导的功能涂料团队在石墨烯高效物理分散技术、石墨烯防腐阻隔机理和石墨烯基重防腐涂料环境适应性评价方面取得重要研究成果,通过实验室小试、工厂扩试和国网浙江省电力公司宁波供电公司示范工程应用结合的方式,首次将石墨烯新材料应用到国家电网输电铁塔防腐实践中,并取得良好的防护效果。
[Abstract]:Graphene is a new two-dimensional layered carbon material with high aspect ratio, excellent water vapor barrier, conductive, thermal conductivity and chemical stability. It has a broad market application prospect in the field of heavy anticorrosive coatings. At present, the base material of transmission tower of State Grid mainly adopts carbon steel substrate, and the surface is protected by zinc plating. Good anticorrosion effect has been achieved. In recent years, with the increase of atmospheric pollution, especially the industrial atmospheric corrosion zone and coastal marine atmospheric corrosion zone. Due to the coupling effect of acid rain (mainly composed of nitrogen oxide and sulfur oxide) and corrosive chloride ions, the galvanized coating has serious corrosion failure and shedding, and even corrosion and perforation. The paper mainly introduces the anticorrosion mechanism of functional coatings research team in graphene based heavy anticorrosive coatings in key laboratory of marine new materials and applied technology of Chinese Academy of Sciences. Yes. And sharing the paint development and application experience. Wang Liping researcher led the functional paint team in graphene high efficiency physical dispersion technology. Important research results were obtained in the aspects of anti-corrosion barrier mechanism of graphene and environmental adaptability evaluation of graphene based heavy anticorrosive coatings. The new graphene material has been applied to the anticorrosion practice of transmission tower of State Grid for the first time in combination of factory expansion and demonstration engineering application of Ningbo Power supply Company of Zhejiang Power Company and good protective effect has been obtained.
