摘　　要：为解决管道结垢带来严重的经济损失和安全隐患,将超疏水涂层喷涂在管道内壁表面形成一层保护膜,以阻止流体与管壁的直接接触,研究以环氧树脂为基体,通过添加二氧化硅和氧化铝来构建表面微纳米结构,设计制备了EP-SiO_(2)/Al_(2)O_(3)超疏水涂层,通过调控2种无极纳米粒子的添加量优化涂层配方,并考察EP-SiO_(2)/Al_(2)O_(3)复合涂层的疏水和防垢性能。结果表明,当各投入5.1%SiO_(2)和5.1%Al_(2)O_(3)时涂层附着力为1级,同时接触角可达154.6°,复合涂层的垢结量明显降低,仅为同等状态下环氧涂层的16.5%。为减少油田管道的结垢和腐蚀,提高油田的经济效益和安全效益提供可行途径。In order to solve the serious economic losses and safety hazards caused by pipeline scaling,the superhydrophobic coating was sprayed on the surface of the inner wall of the pipeline to form a protective film to prevent the direct contact between the fluid and the pipe wall.The surface micro-nano structure was constructed by adding silica and alumina using epoxy resin as the matrix,the EP-SiO_(2)/Al_(2)O_(3)superhydrophobic coating was designed and prepared,the coating formula was optimized by adjusting the addition amount of two electrode nanoparticles,and the hydrophobic and anti-scale properties of EP-SiO_(2)/Al_(2)O_(3)composite coatings were investigated.The results showed that when 5.1%SiO_(2)and 5.1%Al_(2)O_(3)were added respectively,the adhesion of the coating was level 1,and the contact angle could reach 154.6°,and the amount of fouling of the composite coating was significantly reduced,which was only 16.5%of that of the epoxy coating in the same state.It provides a feasible way to reduce the fouling and corrosion of oilfield pipelines and improve the economic and safety benefits of oilfield.
