摘　　要：采用静态失重法评价了一种双喹啉季铵盐QAD在盐酸体系中对N80钢的缓蚀性能,研究了丙炔醇对主缓蚀剂QAD的协同效应和非离子表面活性剂OP-10的增效作用,得到一种新型高效的复合缓蚀剂QBP-1。通过动电位极化扫描和交流阻抗测定研究了QBP-1在盐酸酸化体系中的电化学行为。The corrosion inhibition performance of a double quinoline quaternary QAD to N80 steel was evaluated using the static weight loss method in hydrochloric acid system.The synergistic effect of propargyl alcohol for QAD and its synergism with non-ionic surfactant OP-10 were studied,and a new highly efficient combined corrosion inhibitor QBP-1 was obtained.By determining potentiodynamic polarization and AC impedance,the electrochemical behavior of QBP-1 was studied in hydrochloric acid system.
