摘　　要：采用正交试验、单因素试验、电化学测试和扫描电镜等方法,研究了铝合金表面清洗剂中表面活性剂组分、各类助剂组分、清洗温度和清洗时间对清洗效率的影响以及所制备水基清洗剂对铝合金基体的腐蚀性。结果表明:清洗剂母液中表面活性剂组分的最佳配比为十二烷基苯磺酸钠1.5 g·L^-1、辛基酚聚氧乙烯醚8.0 g·L^-1、脂肪醇聚氧乙烯醚8.0 g·L^-1、壬基酚聚氧乙烯醚4.0 g·L^-1,各类助剂组分的最佳配比为硅酸钠1.0 g·L^-1、聚二甲基硅氧烷0.1 g·L^-1、钼酸钠0.2 g·L^-1、乙二胺四乙酸二钠0.2 g·L^-1;将母液与自来水按体积比1∶20混合均匀后得到工作液,工作液的最佳清洗温度为40℃、最佳清洗时间为5 min;与市售清洗剂相比,自制清洗剂的清洗效率略高但腐蚀性明显降低。In this paper,the effects of surfactant components,additives,cleaning temperature and time on the cleaning efficiency of aluminum alloy surface cleaning agent and the corrosion of the prepared water-based cleaning agent on aluminum alloy substrate were studied by orthogonal test,single factor test,electrochemical test and scanning electronmicroscope.The results showed that in themother fluid of the prepared water-based cleaning solution,the optimal content of surfactant component was SDBS 1.5 g·L^-1,OP-108.0 g·L^-1,AEO-98.0 g·L^-1 and TX-104.0 g·L^-1,and the optimal content of assistant component was Na2SiO31.0 g·L^-1,PDMS 0.1 g·L^-1,Na2MoO40.2 g·L^-1 and EDTA-2Na 0.2 g·L^-1.The operating fluid of the prepared water-based cleaning solution was obtained by mixing mother fluid and tap water with the volume ratio of 1 to 20.In the operating fluid,the optimal cleaning temperature and time were 40℃and 5 min,respectively.Compared with a commercial surface cleaning agent,the prepared water-based cleaning agent exhibited both high efficiency and low corrosion.
