Surface treating agent, aluminum bar treating method and application

The invention discloses a surface treating agent, an aluminum bar treating method and application. The treating agent is prepared from, by weight, 3-8 parts of 30% sulfuric acid solution, 0.2-0.5 part of isomeric alcohol oleic soap, 0.1-0.3 part of triethanolamine borate and 0.1-0.5 part of surfactant. The surface treating agent can deeply clean grease on a surface, the surface corrosion degree and the uniformity of the corrosion surface roughness are remarkably improved by combining an acid pickling effect with a slow-release reagent, and therefore the adhesive force of a metal surface in the coating process is improved, and the coating quality is improved. 本发明公开了一种表面处理剂、铝棒处理方法及应用，所述处理剂按重量份包括30％硫酸溶液3-8份、异构醇油酸皂0.2-0.5份、三乙醇胺硼酸酯0.1-0.3份、表面活性剂0.1-0.5份；所述表面处理剂可以深度清理表面的油脂，通过酸洗作用结合缓释试剂显著提高表面咬蚀程度以及咬蚀面粗糙度的均一性，从而提高金属表面在涂装过程中的附着力，提高涂装质量。
