High-strength scaffold steel pipe and preparation process thereof
The invention relates to the technical field of steel pipes, in particular to a high-strength scaffold steel pipe and a preparation process thereof.By adjusting parameters and raw materials, a zinc, nickel and composite nanometer titanium dioxide gradient coating is formed on a Q235 steel pipe; 2-aminoterephthalic acid, tetrabutyl titanate and glacial acetic acid are selected to prepare an aminated titanium-based framework, ZIF-8 is synthesized on the aminated titanium-based framework in situ through zinc nitrate and dimethylimidazole, and the ZIF-8 and nano titanium dioxide are blended to prepare composite nano titanium dioxide; a gradient plating layer formed on the surface of the Q235 steel pipe is coated with a self-repairing protective coating compounded by composite nano titanium dioxide and organic silicon modified polyurethane, and the Q235 steel pipe is endowed with lasting corrosion resistance and super-hydrophobicity while holes are further sealed.
本发明涉及钢管技术领域，具体是一种高强度脚手架钢管及其制备工艺，通过调整参数及原料，在Q235钢管上形成锌、镍、复合纳米二氧化钛梯度镀层；选用2‑氨基对苯二甲酸、钛酸四丁酯、冰乙酸制备氨基化钛基骨架，利用硝酸锌、二甲基咪唑在氨基化钛基骨架上原位合成ZIF‑8，与纳米二氧化钛共混制备复合纳米二氧化钛；在Q235钢管表面形成的梯度镀层上涂覆复合纳米二氧化钛与有机硅改性聚氨酯复配的自修复性防护涂料，在进一步封孔的同时，赋予Q235钢管持久的抗腐蚀性、超疏水性。
