摘　　要：以尿素作为沉淀剂,确定硝酸镁和硝酸铝浓度比为 2∶1;采用均匀沉淀法合成了Mg2+-Al3+_CO32--LDHs层状材料. 以Mg2 + -Al3 + _CO32 --LDHs为前驱体,分别与NaCl、十二烷基磺酸钠(CH (3 CH2) 10 CH2SO3Na)进行离子交换反应,成功地构建了Mg2 +-Al3 + -CH3(CH2)10 CH2SO3 - -LDHs防腐缓蚀剂.将此样品和粘合剂、无水乙醇按照10∶1∶20的比例混合涂层在钢铁挂片上,制作成压片,通过测极化曲线,用称重法做对比实验对该材料的防腐性能进行研究.Taking urea as precipitant,Mg2+_Al3+_CO32-_LDHs layered materials were synthesized by homogeneous precipitation method under magnesium nitrate and aluminum nitrate concentration ratio of 2:1.Then the corrosion inhibitor of Mg2+_Al3+_CO32-_LDHs was successfully prepared through ion exchange with NaCl and(CH3(CH2)10CH2SO3Na)respectively using Mg2+_Al3+_CH3(CH2)10CH2SO3-_LDHs as precursor.The mixture of samples,adhesive and ethanol with the ratio of 10∶1∶20 was coated on steel hanging piece.By measuring the polarization curve and contact angle,carrying out comparative experiments with weighting method,the corrosion resistance of the material was studied.
