Shell structure of decorative membrane body

A shell structure having a decorative film body, in particular, a material having a decorative or functional film body provided with one or more layers for reattaching to other materials for dry coating purposes, and obtaining a similar tradition The coating effect can reduce the environmental pollution caused by the painting process and make a shell have a special texture.

Existing 3C products, such as handheld communication products, desktop computers, notebook computers, and flat panels, are mostly made of plastic casings. However, the texture of the plastic casing is easy to cause consumer dislike, so manufacturers will use coating technology. The plastic casing has a metallic texture to enhance the texture of the 3C product. In addition to giving the product a metallic feel, the coating technology has the purpose of protecting the coated object, extending its service life, decorating the appearance and special purpose.

However, the existing coating process is a wet coating technique, and the materials used are pigments, resins (Resin), solvents (Solvents), additives (Additive), or a composition of at least two of the foregoing, in coating. It is easy to cause environmental pollution during the process.

The wet coating technique described above has the disadvantage of environmental pollution, and the industry is developing a casing structure having a decorative membrane body, which achieves a similar traditional coating effect and reduces environmental pollution.

However, the existing shell structure of the decorative membrane body is a decorative or functional membrane body, and the membrane body is provided with one or more layers of material, so that the material can be attached to the membrane body and can be attached. In other materials, to achieve a similar traditional coating effect. The membrane structure can change its number of layers as the consumer demands. However, the number of layers of the film body increases more and more, and the film body over a plurality of layers invisibly increases the manufacturer's success at the time of manufacture. Therefore, how to reduce the number of layers of the film body or reduce the cost of the manufacturer, and the housing structure having the decorative function is in need of improvement.

In view of the above disadvantages, the purpose of the present invention is to provide a shell structure having a decorative film body, which is a multi-layer structure, and each layer has multiple functions to reduce the environment caused by the conventional coating process. Contamination, and the shell has a special texture.

In order to achieve the above object, the technical means of the present invention is to provide a shell structure having a decorative film body, comprising: a first functional layer, which is a composite functional layer or a single functional layer; a functional layer disposed on one side of the first functional layer, the second functional layer being a single functional layer or a composite functional layer; and a casing disposed on the first functional layer not facing the first One side of the two functional layers.

In one embodiment, the composite functional layer is a combination of an adhesive layer and a hardened layer or a back layer, a printed layer and a hardened layer; the single functional layer is a printed layer, a paint layer, and an adhesive layer. Or a metal layer.

In one embodiment, the hardened layer is a metal layer or an ultraviolet hardening layer; the printed layer is a layer having text or graphics or the printed layer has a specific color or a portion of the printed layer has a specific color; The metal layer is an antenna layer, an antibacterial layer or an anti-electromagnetic wave layer.

In one embodiment, the specific color is such that the printed layer exhibits a special texture, a pearlescent color, a metallic color, or a combination of at least two of the foregoing; the special texture causes the printed layer to exhibit a similar paint texture. The similar paint texture is a high gloss texture, a matte texture, a color texture, a leather texture, a metallic texture, or a combination of at least two of the foregoing.

In one embodiment, a third functional layer is disposed on the second functional layer that does not face one of the first functional layers, and the third functional layer is a composite functional layer or a single functional layer. .

In summary, the first functional layer of the creation can be a composite functional layer or a A single functional layer. The other functional layers, such as the second functional layer and the third functional layer, can also be designed for this purpose, so each functional layer is a layer with multiple effects or a single function, so the membrane body with the decorative function of the present creation The shell structure can be designed according to the combination of various functional layers to reduce the environmental pollution caused by the traditional painting process, and can make the shell have a special decorative effect, such as metal texture.
