合成了油酸咪唑啉和丙烯酸咪唑啉化合物,通过红外谱对其进行了结构表征;用Tafle曲线和交流阻抗等方法研究了其对铝箔的缓蚀作用,并研究了其对铝箔直流扩面增容的影响。结果表明,在2.0 mol/L的HCl溶液中两种化合物对铝箔均有缓蚀作用,为阴极型缓蚀剂,腐蚀液中添加两种化合物后,铝箔直流扩面的蚀孔密度增加、分布均匀、使铝箔的比电容提高约25%。 The oleic acid imidazoline and imidazoline compounds were synthesized and their structures were characterized by IR. The corrosion inhibition effect on aluminum foil was studied by Tafle curve and AC impedance method. Affect the capacity. The results show that both compounds have a corrosion inhibition effect on the aluminum foil in 2.0 mol / L HCl solution, which is a cathode inhibitor. After adding two compounds to the etching solution, the hole erosion density increases and the distribution of distribution Uniform, so that the specific capacitance of aluminum foil increased by about 25%.
