摘要: 

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%。

Abstract

The oleic acid imidazoline and acrylic acid imidazoline were synthesized and their structures were characterized by IR spectrum. Their inhibition behaviors for aluminium foil in 2.0 mol/L HCl solution were studied by polarization curves and electrochemical impedance methods. The influences of specific capacitance of the two imidazolines on aluminium foil for electrolytic capacitors during DC etching were investigated by capacitance measuring instrument and SEM. The results show that the two compounds were both cathodic corrosion inhibitors for aluminium foil in 2.0 mol/L HCl solution. The inhibition efficiency of acrylic acid imidazoline was better than oleic acid imidazoline. Of the etched aluminum foil, weight loss decreased, tunnel density increased and well distributed, specific capacitance increased by 25% when inhibitors added in 2.0 mol/L HCl solution.
