High-temperature-resistant high-bonding-performance geopolymer metal anti-corrosion coating and preparation method thereof
The invention discloses a high-temperature-resistant high-bonding-performance geopolymer metal anti-corrosion coating. The geopolymer metal anti-corrosion coating comprises the following components ofa high-temperature reinforced geopolymer layer and an active metal interface layer, wherein the high-temperature reinforced geopolymer layer comprises 35-60 parts of silicon-aluminum powder, 60-100 parts of an alkali activator and 15-40 parts of high-temperature-resistant fiber, and the active metal interface layer comprises 5-15 parts of aluminum oxide nano powder, 5-15 parts of zinc oxide nanopowder, 5-15 parts of tin oxide nano powder, 50-100 parts of ethyl alcohol, 50-100 parts of methyl alcohol and 50-100 parts of acetone. The invention further discloses a preparation method of the high-temperature-resistant high-bonding-performance geopolymer metal anti-corrosion coating. According to the high-temperature-resistant high-bonding-performance geopolymer metal anti-corrosion coating and the preparation method thereof, the compact active metal interface layer is formed on the surface of a metal component through an aerosol deposition method, and the high-temperature reinforced geopolymer layer is coated on the metal component, so that the corrosion resistance of the metal component treated by the method in a high-temperature environment is obviously enhanced.
本发明公开了一种耐高温高粘结性能地聚物金属防腐蚀涂层，包括以下组分：高温强化地聚物层和活性金属界面层；所述高温强化地聚物层包括硅铝质粉料35‑60份、碱激发剂60‑100份、耐高温纤维15‑40份；所述活性金属界面层包括氧化铝纳米粉末5‑15份、氧化锌纳米粉末5‑15份、氧化锡纳米粉末5‑15份、乙醇50‑100份、甲醇50‑100份、丙酮50‑100份。本发明还公开了一种耐高温高粘结性能地聚物金属防腐蚀涂层的制备方法。本发明通过气溶胶沉积法在金属构件表面形成致密活性金属界面层，并在其上涂覆高温强化的地聚物层，经过本发明处理的金属构件在高温环境下的耐腐蚀性能明显增强。
