Abstract

The invention discloses an elastic vehicle decorative part with a metal appearance. A plastic substrate is manufactured by adopting soft plastics, and the substrate surface is coated with a compound layer of primer film layer-PVD film layer-finishing coat film layer. By using specific primer, finishing coat and other modes, the defect of poor binding force between soft plastics and the compound layer can be overcome while the metal appearance can be ensured for the elastic vehicle decorative part, so that serial functions of stability, abrasion resistance, scratch resistance, corrosion resistance and the like of the compound layer can accord with the setting standard of mainstream vehicle manufactures.

Description

technical field [0001] The invention relates to the technical field of plastic surface treatment, in particular to a surface treatment technology for automobile decoration parts. Background technique [0002] Existing automotive decorative parts want to achieve a metallic appearance, and most of them use hard plastic as the base material for surface treatment. As the automotive consumer market pays more and more attention to safety performance, the problem of sputtering damage caused by the fragmentation and splashing of auto parts that use hard rubber materials as the base material due to safety accident damage has been paid more and more attention. research direction. [0003] Compared with hard rubber plastics, soft rubber plastics have the advantages of wide elastic range, outstanding shock absorption performance, excellent cold resistance, and rich processing methods. Therefore, many automobile manufacturers have begun to pay attention to using soft rubber plastics as ...
