摘要:

石墨烯是一種新型二維層狀結(jié)構(gòu)的碳材料，具有高長徑比、優(yōu)異的阻隔水汽、導電、導熱和化學穩(wěn)定性能，使其在重防腐涂料領域具有廣泛的市場應用前景。目前國家電網(wǎng)輸電鐵塔基材主要采用碳鋼基底，表面通過鍍鋅對基材進行防護，取得良好防腐效果。近年來隨著大氣污染加重，特別是工業(yè)大氣腐蝕區(qū)和沿海海洋大氣腐蝕區(qū)，由于酸雨(主要成分是氮氧化物和硫氧化物)和腐蝕性氯離子的耦合作用，鍍鋅層腐蝕失效和脫落嚴重，甚至出現(xiàn)腐蝕穿孔現(xiàn)象，嚴重影響國家電網(wǎng)安全穩(wěn)定輸電。本文作者主要介紹中國科學院海洋新材料與應用技術(shù)重點實驗室功能涂料研究團隊在石墨烯基重防腐涂料的防腐機理、現(xiàn)場示范工程應用并分享涂料開發(fā)與施工經(jīng)驗。王立平研究員領導的功能涂料團隊在石墨烯高效物理分散技術(shù)、石墨烯防腐阻隔機理和石墨烯基重防腐涂料環(huán)境適應性評價方面取得重要研究成果，通過實驗室小試、工廠擴試和國網(wǎng)浙江省電力公司寧波供電公司示范工程應用結(jié)合的方式，首次將石墨烯新材料應用到國家電網(wǎng)輸電鐵塔防腐實踐中，并取得良好的防護效果。

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.
