摘　　要：以曼尼希碱、丙炔醇、乌洛托品、OP-10为原料,利用复配后产生的协同效应,来抑止和减缓缓速酸对金属的腐蚀速率。结合对N-80钢片在缓速酸中的缓蚀效果,通过正交试验确定最佳的复配方案,研制出价格低廉、效果良好、具有广泛应用前景的适于土酸酸化用的复合缓蚀剂。According to the result of corrosion evalution to N-80 in mud acid,a new complex corrosion inhibitor for mud acid was obtained by orthogonal test.This inhibitor was composed of Mannich base,Hexamethyleneletramine,Propargyl alcohol and OP-10.It can restrain and reduce the corrosion speed of metal and have an effective inhibiting performance.In addition,it has a low price.So it has a good application future.
