The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a method for manufacturing a decorative part according to an embodiment of the present disclosure. The embodiment of the application provides a preparation method of a decorating part, which comprises the following steps:
100, a substrate is obtained, the substrate having an inner surface and an outer surface disposed opposite one another.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a substrate according to an embodiment of the present disclosure, in which a substrate 10 has an inner surface 11 and an outer surface 12 disposed opposite to each other. Illustratively, the substrate 10 may be glass, such as silicate glass or lithium aluminosilicate glass, among others.
Illustratively, the thickness of the substrate 10 may be 0.3mm to 3.0mm, such as 0.3mm, 0.5mm, 0.7mm, 1mm, 1.3mm, 1.5mm, 1.7mm, 2mm, 2.3mm, 2.5mm, 2.7mm, 3.0mm, and the like.
Illustratively, the outer surface 12 of the substrate 10 may be smooth.
Illustratively, the outer surface 12 of the substrate 10 may also have a glittering, anti-glare (AG) texture pattern or a low-glittering, anti-glare (AG) texture pattern.
Illustratively, after the substrate 10 is obtained, the substrate 10 may also be pre-processed.
Fig. 3 is a flowchart of preprocessing a substrate according to an embodiment of the present disclosure, and as shown in fig. 3, "preprocessing a substrate" may specifically include:
and 110, grinding the base material into a preset shape.
Illustratively, the substrate 10 may be ground to a predetermined shape, such as a rectangular shape or a circular shape, using a CNC machine. When the substrate 10 is a glass plate, the glass plate may be ground into a 2.5D shape using CNC equipment.
Illustratively, when the substrate 10 is a glass plate, after grinding the substrate 10 into a predetermined shape such as a rectangle, a circle, etc., the substrate 10 may be processed into a 3D shape using a hot bender.
And 120, polishing the edge of the substrate.
It is understood that, after the grinding of the substrate 10, the edge of the substrate 10 is frosted due to the knifes and pocks, and thus the edge of the substrate 10 can be smoothed by polishing the edge of the substrate 10.
130, polishing the outer surface of the substrate.
It will be appreciated that by polishing the outer surface 12 of the substrate 10, the optical effect and thus the appearance of the subsequently produced decorative element 100 can be enhanced.
Note that, when the outer surface 12 of the substrate 10 originally exhibits the glittering and antiglare effect, the outer surface 12 of the substrate 10 may not be subjected to polishing treatment.
140, forming a via hole in the substrate.
For example, after the through hole is formed in the substrate 10, when the decoration member to be subsequently manufactured is used for attaching the electronic device, the through hole may be disposed corresponding to the camera so that the decoration member is decorated around the camera.
150, strengthening the base material.
For example, when the substrate 10 is glass, the glass may be strengthened by ion exchange, so as to improve the strength of the glass, and further improve the strength and wear resistance of the subsequently manufactured decoration.
200, a shielding layer is arranged on the outer surface of the base material, and a first hollow area is arranged on the shielding layer.

Illustratively, the material of the shielding layer 20 may be a resin, such as an acrylic resin, an epoxy novolac resin, or the like.

The laminated structures of Cr/CrWC/WC, Cr/CrSiCN, Ti/TiSiCN and the like can realize the appearance effect of imitation ceramics, have higher hardness, and the wear resistance can reach the wear resistance level of stainless steel, so that the appearance aesthetic feeling of the decoration 100 is improved, and the wear resistance of the outer surface of the decoration 100 is improved.
