Technical Field

The invention belongs to the technical field of chemical cleaning agents, and particularly relates to a surface cleaning agent.

Background

Aluminum alloys have been widely used in the aerospace, automotive, mechanical manufacturing, marine and chemical industries due to their advantages of low density, high strength, strong corrosion resistance, good processability and easy regeneration, and have become the most widely used non-ferrous metal structural materials. However, the surface of the aluminum alloy product is easily polluted by various oil stains and dust in the manufacturing and using processes, and yellow spots, oil stain stains and tarnish are generated by oxidation, so that the aluminum alloy product needs to be cleaned regularly. In the related art, cleaning is performed by a chemical method of wiping with a soda solution, but reaction products such as sodium metaaluminate and aluminum hydroxide remaining after cleaning are attached to the surface to whiten the surface, and meanwhile, acid washing and alkali washing can damage an oxidation protection film on the surface of the aluminum alloy, so that a galvanic cell is formed among various metal ions on the surface of the aluminum alloy, and further corrosion, oxidation and yellowing occur, and the appearance of the aluminum alloy is affected.

Therefore, there is a need to provide a new surface cleaning agent to solve the above technical problems.
