Problems solved by technology
[0003] Due to the thickness of the paint film, the CASS test (copper acetate accelerated corrosion test) of painted products can meet the requirements of most OEMs for 240 hours, but the appearance is relatively poor, and there are fish scale-like orange peel patterns visually, CF ≥55; while anodized products have a good appearance and no fish-like orange peel visually, but limited by the process, their CASS performance usually only meets 48h
The known coating on the anodized film layer can take into account both appearance and performance, but the problem of adhesion between the paint film and the oxide layer needs to be solved urgently

Abstract
The invention relates to a surface treatment method of an aluminum alloy decorative piece and aluminum alloy decorative piece manufactured by the surface treatment method. The surface treatment methodis characterized by comprising the following steps of S1, performing anodic oxidation treatment on an aluminum material to form an oxide film layer on the surface of the aluminum material; S2, performing hole sealing operation on the oxide film layer to form a hole sealing layer on the surface of the oxide film layer; S3, applying a connecting layer on the surface of the hole sealing layer by using a connecting layer medicament; S4, performing spraying operation on the surface of the connecting layer by using organic paint to form a paint film layer on the surface of the connecting layer. Thesurface treatment method has higher corrosion resistance and better appearance, and solves the problem of weak paint film adhesion in traditional aluminum products by arranging the connecting layer,thus greatly improving the quality of the products.
Description
technical field [0001] The invention relates to an aluminum material processing technology, in particular to a surface treatment method for an aluminum alloy decorative part. [0002] The present invention also relates to an aluminum alloy decorative part manufactured by the above surface treatment method. Background technique [0003] Due to the thickness of the paint film, the CASS test (copper acetate accelerated corrosion test) of painted products can meet the requirements of most OEMs for 240 hours, but the appearance is relatively poor, and there are fish scale-like orange peel patterns visually, CF ≥55; while anodized products have a good appearance and no fish-like orange peel visually, but limited by the process, their CASS performance usually only meets 48h. The known coating on the anodized film layer can take both appearance and performance into account, but the problem of adhesion between the paint film and the oxide layer needs to be solved urgently.
