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。本文作者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、现场示范工程应用并分享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 (G) is a new type of two-dimensional layered structure carbon material, which has high aspect ratio, good thermal conductivity, excellent hydrophobic property, electrical conductivity and chemical stability, so it has a wide application prospect in anti-corrosion coatings. The transmission tower usually uses galvanized steel as base material and achieved good anti-corrosion effect. In recent years, with the increase of air pollution, especially in the industrial atmospheric corrosion zone and the coastal marine atmospheric corrosion zone, due to the coupling effect of acid rain (the main component is nitrogen oxide and sulfur oxides) and corrosive chloride ion, galvanized corrosion failure and even corrosion perforation phenomenon have a serious impact on national power grid security and stability of transmission. The author mainly introduced the corrosion protection mechanism of the functional coatings research team of the key laboratory of marine new materials and applied technology. We also glad to share the construction experience of coating. The marine functional materials team guided by professor Wang has achieved important research findings on G based heavy duty coatings, including the efficient physical dispersion technology of G, the corrosion barrier mechanism of G, and the environmental adaptability evaluation of G coating. Through laboratory test and factory test, the new material, G, has been first applied to the corrosion prevention of the transmission tower in the national power grid. We obtained good protective effect on transmission tower.
