采用化学氧化法合成了胺醛缩聚物,并利用扫描电镜(SEM)、红外光谱(FTIR)测定该聚合物的结构和形貌.采用失重、极化曲线及电化学阻抗法研究胺醛缩聚物对Q235钢在1.0 mol/L的HCI溶液中的缓蚀性能.结果表明:胺醛缩聚物为阳极型缓蚀剂,在Q235碳钢表面形成保护膜,减缓金属的腐蚀. Amino aldehyde polycondensate was synthesized by chemical oxidation and the structure and morphology of the polymer were determined by scanning electron microscopy (SEM) and infrared spectroscopy (FTIR). The effects of amine aldehyde polycondensation on weight loss, polarization curve and electrochemical impedance spectroscopy The corrosion inhibition performance of Q235 steel in 1.0 mol / L HCl solution was investigated.The results showed that the amine aldehyde condensation polymer was anodic corrosion inhibitor and formed a protective film on the surface of Q235 carbon steel to slow down the corrosion of metal.
