Preparation method of micro-nano multi-level bionic super-hydrophobic coral sand anticorrosive coating
The invention belongs to the technical field of corrosion prevention of ocean engineering concrete, and particularly discloses a preparation method of a micro-nano multi-level bionic super-hydrophobic coral sand anti-corrosion coating. The method comprises the following specific steps that S1, a certain amount of coral sand is taken and ground, ground coral sand is prepared, and the average particle size of the ground coral sand is 150 nm; s2, adding a certain amount of stearic acid into absolute ethyl alcohol, stirring and dissolving to prepare a stearic acid solution; s3, adding a certain amount of ground coral sand into a stearic acid solution, and stirring to obtain super-hydrophobic ground coral sand; s4, spraying the super-hydrophobic ground coral sand on the surface of the newly poured concrete; and S5, after spraying, concrete is cured and dried, and the micro-nano multi-level bionic super-hydrophobic coral sand anti-corrosion coating is formed. The super-hydrophobicity of the coral sand is realized by utilizing an environment-friendly method, a way for applying the coral sand to the concrete is provided, and the corrosion resistance of the ocean engineering concrete is improved.
本发明属于海洋工程混凝土的防腐技术领域，具体公开了一种微纳米多层级仿生超疏水珊瑚砂防腐涂层的制备方法。具体步骤如下：S1、取一定量的珊瑚砂，研磨，制得磨细珊瑚砂，所述磨细珊瑚砂的平均粒径为150nm；S2、取一定量的硬脂酸加入无水乙醇中，搅拌溶解，制得硬脂酸溶液；S3、将一定量的磨细珊瑚砂加入硬脂酸溶液中，搅拌，制得超疏水磨细珊瑚砂；S4、将超疏水磨细珊瑚砂喷射于新浇筑的混凝土表面；S5、喷涂后，混凝土养护干燥，形成微纳米多层级仿生超疏水珊瑚砂防腐涂层。本发明利用环保的方法实现珊瑚砂的超疏水性，提供了珊瑚砂应用于混凝土的途径，提高了海洋工程混凝土的耐腐蚀性。
