Surface cleaning agent

The invention belongs to the technical field of chemical cleaning agents, and particularly relates to a surface cleaning agent. The surface cleaning agent is composed of the following components of, in percentage by weight, 10-15% of phosphating solution, 6-25% of an aluminum ion complexing agent, 1.5-8.5% of a foaming type anionic surfactant, 1-12% of a nonionic surfactant, and the balance water.Compared with the prior art, the surface cleaning agent has the advantages that the aluminum ion complexing agent, the foaming surfactant and the phosphide are added, so that the aluminum alloy surface cleaning speed is greatly increased, the problems of whitening and yellowing of the surface in traditional chemical cleaning are avoided, and the original gloss of the aluminum alloy surface can berecovered. 本发明属于化学清洗剂技术领域，具体涉及一种表面清洗剂。按重量百分比计由以下组份组成：磷化液，10～15％；铝离子络合剂，6～25％；发泡型阴离子表面活性剂：1.5～8.5％；非离子表面活性剂，1～12％；余量，水。与相关技术相比，本发明一种表面清洗剂通过添加铝离子络合剂和发泡型表面活性剂以及磷化物，大大提升了铝合金表面清洗速度，避免了传统化学清洗表面发白、发黄问题，使铝合金表面能够恢复其原有光泽。
