Description

[0001] technical field [0002] The invention mainly relates to the field of surface treatment, in particular to an aluminum alloy surface treatment agent containing seabuckthorn oil. Background technique [0003] There are many surface treatment methods for aluminum alloys, such as physical methods, chemical methods, physicochemical methods, and comprehensive methods. The commonly used method is the anodic oxidation method, which forms a conversion film on the surface of the aluminum alloy by an electrochemical method. Although this method can improve the performance of the aluminum alloy containing seabuckthorn oil, its ability to adapt to the environment is poor, and the conversion film layer is not uniform enough. It is easy to fall off, and the wear resistance has not been improved. Although the traditional phosphate conversion and chromate passivation surface treatment technology can obtain good results, the waste liquid discharged during the treatment process contai...

Problems solved by technology

The commonly used method is anodic oxidation method, which forms a conversion film on the surface of aluminum alloy by electrochemical method. Although this method can improve the performance of seabuckthorn oil in aluminum alloy, it has poor ability to adapt to the environment, and the conversion film layer is not uniform enough. It is easy to fall off, and the wear resistance has not been improved. Although the traditional phosphate conversion and chromate passivation surface treatment technology can obtain good results, the waste liquid discharged during the treatment process contains zinc, manganese, nickel, chromium, etc. Heavy metal ions and carcinogens such as sub-seabuckthorn oil are very serious environmental pollution, and the metal surface silanization treatment technology does not involve substances harmful to the environment, the production process has low energy consumption, and the technology has a wide range of application fields. It is considered to be expected to replace phosphate Conversion treatment and chromate passivation treatment are the latest development direction of metal surface protection alone
