Description

A decorative shell

Technical field:

The utility model relates to the technical field of decorative materials, in particular to a shell decorative sheet.

Background technique:

Seashells are natural products with rich and elegant surface textures and colors. They can be used as decorative materials for watches, dials, jewelry, glasses, mobile phones, etc., to increase the beauty. Taking the watch industry as an example, shell pieces are used to make watches literally. The treatment method of raw materials of shell pieces, one is the translucent method, which uses paint spraying technology to change the color of shells. The original texture; the other is to use the dyeing method to change the color of the shell. The shell pieces produced by the above methods have no beautiful metallic color. At the same time, the back side of the shell piece is colored by the light transmission method, and the front side still has the original color of the shell, and the dyeing method has great damage to the shell itself. Different cell densities lead to uneven staining.

Utility model content:

The purpose of the utility model is to provide a shell decorative sheet with uniform metal or ceramic color and luster while retaining the shell texture.

In order to achieve the above object, the utility model adopts the following technical solutions:

A shell decoration sheet, which comprises a shell sheet base material, the outer surface of the base material is plated with a layer of metal film or ceramic film.

Wherein, the film thickness of the metal film or ceramic film is not more than 1 micron.

A layer of pre-plated titanium film is arranged between the base material and the film.

The beneficial effect of the utility model is that: because a layer of metal or ceramic film is plated on the outer surface of the shell piece base material, it has a uniform metal or ceramic color, and at the same time, the shell texture is retained because the film is closely attached to the outer surface of the shell.

Description of drawings:

Accompanying drawing 1 is the structural representation of the utility model.

Detailed ways:

Below in conjunction with the accompanying drawings the utility model is further described, see shown in Figure 1, a shell decorative sheet, it includes a shell sheet base material 1, the base material 1 is made by cutting and polishing shells, the base The outer surface of the material 1 is coated with a layer of metal or ceramic thin film 2, so that the outer surface of the base material 1 has a uniform metal or ceramic luster, and because the thin film 2 is closely attached to the outer surface of the base material 1, the shell texture is retained.

The thickness of the thin film 2 in this embodiment is not more than 1 micron.

A layer of pre-plated titanium film 3 is arranged between the base material 1 and the film 2 described in this embodiment. During processing, titanium ions are used to impact the outer surface of the shell base material 1, on the one hand to remove pollutants on the outer surface of the base material 1, and on the other hand On the one hand, activating the outer surface of the substrate 1 will make the coating of the substrate 1 smoother and more uniform. This process will form a very thin and almost transparent titanium film 3 on the outer surface of the substrate, and then coat the pre-coated titanium film 3 on this layer. A layer of metal or ceramic film 2 is coated on the titanium film 3 .

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .

Claims (3)
