As shown in Figure 1, an embodiment of the present application provides a housing, which includes a transparent protective layer 1, a light-transmitting layer 2 and a light-shielding color layer 3 that are stacked in sequence. That is, the light-transmitting layer 2 is used as the skeleton of the housing. A protective layer 1 and a light-shielding color layer 3 are respectively provided on the two sides of the light-transmitting layer 2 facing away from each other.

Among them, the transparent protective layer 1 is the exposed layer of the casing, facing the external environment, and has high hardness. On the one hand, it can prevent the external environment from causing wear and tear on the light-transmitting layer 2 or the light-shielding color layer 3 in the casing, and maintain the casing. appearance effect. On the other hand, the structure located inside the casing (for example, the electronic device located within the casing of the electronic device) is protected from damage by the external environment.

In one example, the transparent protective layer 1 can be an ultraviolet (UV) varnish hardened layer, that is, spraying UV varnish on the light-transmitting layer 2 and then irradiating it with a UV lamp, so that the UV varnish solidifies into a solid, forming UV varnish hardened layer. The UV varnish hardened layer is scratch-resistant and has high light transmittance and good gloss, giving the shell a glass texture and improving the aesthetics of the shell.

Among them, the dye may be a quinophthalone series. The quinophthalone series has high coloring power and high heat resistance stability, which can ensure the stability of the appearance effect presented by the light-transmitting layer 2 . For example, quinophthalone pigment yellow 138 has bright, strong green light and excellent color rendering. By mixing quinophthalone pigment yellow 138 into the first transparent base material, the light-transmitting layer 2 can appear green and Transparent appearance effect.

Optionally, the dye can also be beryllium ketone series, which is usually red or yellow. By mixing the beryllium ketone system into PC, the light-transmitting layer 2 can exhibit a red or yellow and transparent appearance.

It is worth noting that, in one embodiment, a dye can be uniformly mixed into the first transparent base material, so that the entire light-transmitting layer 2 presents a corresponding color. The dye can also be mixed into a partial area of the first transparent substrate, so that a partial area of the light-transmitting layer 2 presents a corresponding color. In another embodiment, multiple dyes can also be mixed into different areas of the first transparent substrate, so that the light-transmitting layer 2 can present a richer colorful effect. For example, as shown in Figure 2, the light-transmitting layer 2 can be divided into two areas: a middle area 21 and an edge area 22. Pigment yellow 110 is mixed into the PC of the middle area 21, so that the middle area of the light-transmitting layer 2 21 is reddish-yellow; thioindigo is mixed into the PC in the edge area 22 to make the edge area 22 of the light-transmitting layer 2 appear blue-red. In this way, the light-transmitting layer 2 as a whole can present a richer colorful effect and improve the transparency. The aesthetics of light layer 2. In this way, the light-transmitting layer 2 provided by the present application can exhibit more, richer, and more colorful appearance effects by selecting different dyes.

In one example, by mixing pigment particles with the first transparent substrate, the light-transmitting layer 2 can be provided with a special colorful effect. For example, glitter effect, fluorescent effect, etc. Therefore, there is no need to add an additional glitter sand layer with brilliant effect particles such as glitter sand, which simplifies the structure of the shell and is conducive to the development of thinner and lighter electronic devices.

The pigment particles may be mica-based pearlescent particles, for example, silver-white mica titanium series, interference color mica titanium series or colored mica titanium series. For example, silver-white titanium mica or interference-colored titanium mica can be incorporated into the first transparent base material. In this way, the light-transmitting layer 2 can exhibit a pearlescent appearance.

Optionally, the pigment particles can also be metal powders, such as aluminum powder, zinc powder, lead powder, gold powder, zinc-aluminum powder, stainless steel powder, etc. Taking aluminum powder as an example, mixing the aluminum powder into the first transparent base material can cause the light-transmitting layer 2 to exhibit a yellow flashing appearance.

Alternatively, the pigment particles may be surface metal oxide particles.

The above pigment particles are only illustrative examples, and this application does not impose specific restrictions on the materials of the pigment particles.

It is worth noting that, in one embodiment, a kind of pigment particles can be uniformly mixed into the first transparent base material, so that the light-transmitting layer 2 as a whole exhibits a corresponding appearance effect. Pigment particles can also be mixed into partial areas of the first transparent substrate, so that partial areas of the light-transmitting layer 2 exhibit corresponding appearance effects. In another embodiment, a variety of pigment particles can also be mixed into the first transparent base material, so that the light-transmitting layer 2 can present a richer colorful effect. In this regard, this application does not impose specific restrictions.

In another example, the first filler can include both dye and pigment particles, so that the light-transmitting layer 2 itself can have a more brilliant and richer colorful effect. For example, silver-white mica titanium and thioindigo are mixed into the first transparent base. In the material, the light-transmitting layer 2 presents a pearlescent and bluish-red appearance. Therefore, there is no need to add additional red color layers and pearlescent effect layers, which not only simplifies the structure of the housing, but also makes the appearance of the housing more gorgeous and rich, improving the aesthetics of the housing.

To sum up, by using different dyes and pigment particles, the light-transmitting layer 2 itself can have flexible and rich colorful effects. There is no need to superimpose additional color layers and glitter sand layers, simplifying the structure of the shell and reducing the cost. The preparation process and process cost of the casing are reduced, which is beneficial to the lightweight and thin design of the casing.

In one example, the light-transmitting layer 2 provided by the embodiment of the present application may also include an improving agent mixed in the first transparent base material, which can further improve the appearance of the light-transmitting layer 2 and ensure the stability of the light-transmitting layer 2 .

Exemplarily, the improving agent may include one or more of antioxidants, dispersants and stabilizers.

Among them, antioxidants can avoid the problem of oxidative discoloration of dye and pigment particles after they come into contact with air. By adding antioxidants, the material properties of dye and pigment particles can be ensured, thereby improving the stability of the appearance effect presented by the light-transmitting layer 2.

Optionally, the antioxidant may include one or more of phenolic antioxidants, phosphite antioxidants and metal ion passivators.

The dispersant can make the dye and pigment particles evenly distributed in the first transparent substrate, ensuring that the appearance effect presented by the light-transmitting layer 2 is evenly distributed, thereby ensuring the aesthetics of the entire shell.

Optionally, the dispersant may include one or more of hydrophilic acrylic copolymer and polyoxyethylene active agent.

The stabilizer can absorb ultraviolet light, avoid the problem of discoloration of dye and pigment particles under the action of ultraviolet light, and ensure the stability of dye and pigment particles, thereby improving the stability of the appearance effect presented by the light-transmitting layer. Exemplarily, the stabilizer can be a UV absorber, for example, it can include UV-531, salicylate stabilizer, benzophenone stabilizer, benzotriazole stabilizer, substituted acrylonitrile stabilizer, triazole stabilizer, etc. One or more of azine stabilizers and hindered amine stabilizers.

In one example, the light-transmitting layer 2 provided in the embodiment of the present application can be prepared by injection molding. The surface of the substrate prepared by injection molding is smooth and scratch-free, and the production efficiency is high. Injection molding refers to injecting completely molten plastic material into the mold cavity at high pressure at a certain temperature. After cooling and solidifying, the injection molded base material is obtained.

For example, taking the first transparent base material as PC, PC has high transparency and free dyeability. Therefore, when the first filler is mixed with PC, the first transparent base material can exhibit the same appearance as The appearance effect corresponding to the characteristics of the first filler ensures the stability of the appearance effect presented by the first transparent base material. The injection molding process of the light-transmitting layer 2 in the embodiment of the present application may be:

Step 1: Set the blast drying oven to 100°C (Celsius), and then put the PC into drying for more than 4 hours to ensure that the PC is dry enough.

Step 2: Put the dye, pigment particles and PC into a high-speed mixer according to the preset appearance requirements to mix the dye and filler into the PC. Then pour the stirred raw materials into the twin-screw extruder, set the temperature of the twin-screw extruder to 220~300°C, and then cut, extrude, cool, blow-dry, and pellet the stirred raw materials to form plastic Particles. It is worth mentioning that the plastic particles prepared here have a gorgeous and rich appearance and can be called aesthetic plastics.

Step 3: Fill these plastic particles into the mold, and then go through processing processes such as pressure maintaining, cooling, and demoulding to obtain a light-transmitting layer 2 that can meet the preset appearance requirements.

It can be understood that the type of dye and pigment particles and the addition ratio can be selected according to the preset appearance requirements so that the finally prepared light-transmitting layer 2 can meet the preset appearance requirements. That is to say, by adjusting the type and proportion of dye and pigment particles, the appearance effect presented by the light-transmitting layer 2 can be flexibly set. For example, during the addition process, each raw material may include 90-99 parts by weight of dry PC, 0.1-0.5 parts by weight of the dye, 0.2-5 parts by weight of the pigment particles, 0.1-99 parts by weight 0.6 parts by weight of antioxidant, 0.05-1 part by weight of dispersant and 0.1-1 part by weight of stabilizer.

The light-shielding color layer 3 provided in the embodiment of the present application has a light-shielding effect and is usually placed facing the interior of an electronic device or non-electronic product to shield the internal structure of the electronic device or non-electronic product. In the embodiment of the present application, the light-shielding color-developing layer 3 may include at least one color area. In this way, the light-transmitting layer 2 is combined with the light-shielding color-developing layer 3 showing at least one color, so that the shell structure has a more layered feel. Richer and more gorgeous appearance effects further improve the aesthetics of the shell.

In one example, as shown in Figure 3, the light-shielding color layer 3 provided by the embodiment of the present application may include a transparent film 31 and at least one color layer 32. The transparent film 31 is disposed on the light-transmitting layer 2 facing away from the transparent protective layer. 1, the color layer 32 is disposed on the side of the transparent film 31 facing away from the light-transmitting layer 2.

Wherein, the transparent film 31 can be a colorless and transparent film, and at least one color layer 32 is provided on the side of the transparent film 31 facing away from the light-transmitting layer 2 , so that the at least one color layer 32 can be formed on the transparent film 31 At least one color area. For example, the at least one color area can be presented as a preset graphic or text, a solid color effect, a spliced color block effect, a gradient color effect, etc., to which this application does not impose specific limitations.

Optionally, the transparent diaphragm 31 can be a polyethylene terephthalate (PET) diaphragm. The PET diaphragm itself is a colorless, transparent, glossy film, and can be light-transmissive by backing the PET diaphragm. The way graphics, text or colors are primed on one side of layer 2 gives it a rich appearance. Moreover, the PET film has high hardness and toughness, which can protect the light-transmitting layer 2 to a certain extent and avoid damage to the light-transmitting layer 2 of the internal structure of electronic equipment or non-electronic products.

The color layer 32 can be disposed on the surface of the transparent film 31 through transfer, coating, coating, etc. It can be understood that the so-called transfer refers to coating the surface of the transparent film 31 with a chromatic image, the so-called coloring refers to coating the surface of the transparent film 31 with a chromatic dye, and the so-called coating refers to coating the surface of the transparent film 31 with a chromatic dye. The surface of the transparent diaphragm 31 is coated with a colored film.

In order to reduce the manufacturing process, in one example, the light-shielding color layer 3 may include at least one color layer 32 , and the color layer 32 may be directly formed on the side of the light-transmitting layer 2 facing away from the transparent protective layer 1 . For example, at least one color area can be directly formed on the side of the light-transmitting layer 2 facing away from the transparent protective layer 1 through transfer, coating, coating, etc., further simplifying the structure of the housing and reducing the complexity and complexity of the manufacturing process. cost.

The light-transmitting layer 2 provided in the embodiment of the present application is provided with dye and pigment particles, so that the light-transmitting layer itself has a flexible and rich colorful effect. There is no need to superimpose additional color layers to achieve color display, and the shell is simplified. The structure reduces the preparation process and process cost of the casing, and is conducive to the lightweight and thin design of the casing. Moreover, the case provided by the embodiment of the present application also combines the light-transmitting layer 2 with the light-shielding color-developing layer 3 showing at least one color, so that the case structure has a richer layered appearance and further improves the appearance of the case. of aesthetics. Therefore, the housing provided by the embodiment of the present application can simplify the structure of the housing while improving the appearance effect.

In one example, as shown in FIG. 4 , the shell provided by the embodiment of the present application may also include a texture layer 4 disposed between the transparent protective layer 1 and the light-transmitting layer 2 . The texture layer 4 itself may have a transparent texture pattern. structure. By adding the texture layer 4, the appearance of the shell has a certain sense of layering and three-dimensionality, which improves the aesthetics of the shell.

Optionally, the texture layer 4 may include a second transparent substrate, and the second transparent substrate may be PC or other transparent plastic.

Optionally, the texture layer 4 may include a second transparent base material and a second filler mixed in the second transparent base material. The second filler may include one or more of dyes and pigment particles. By adding the second filler After being mixed with the second transparent base material, the texture layer 4 itself has a flexible and rich colorful effect. By superimposing the texture layer 4 and the light-transmitting layer 2 on each other, the shell finally presents a more layered and richer appearance. It should be noted that the materials of the dye and pigment particles in the second filler can be the same as the materials of the dye and pigment particles in the first filler, which will not be described again.

In one example, the texture layer 4 and the light-transmitting layer 2 are independent structures. For example, the independent texture layer 4 and the light-transmitting layer 2 are pressed together and arranged. In this example, the materials of the second transparent base material and the second transparent base material may be the same or different, and the materials of the first filler and the second filler may be the same or different. For example, if the first filler and the second filler are different dyes and/or pigment particles, the shell formed by superimposing the texture layer 4 and the light-transmitting layer 2 can have a richer, more layered and colorful appearance. For example, the light-transmitting layer 2 can be a colored light-transmitting layer with fluorescent characteristics, and the texture layer 4 can be a colored light-transmitting layer provided with gold glitter. After the two are stacked, the colors and characteristics will be superimposed, making the shell The result is a layered look with fluorescent properties and gold glitter and layered color effects.

In another example, in order to reduce the manufacturing process, the texture layer 4 and the light-transmitting layer 2 may have an integrated structure. In this case, the first transparent base material and the second transparent base material are the same, and the first filler and the second filler are the same.

Optionally, the texture layer 4 and the light-transmitting layer 2 can be an integrated structure of injection molding. Therefore, there is no need to prepare the texture layer 4 separately, which reduces the manufacturing process.

In one example, the side of the light-transmitting layer 2 facing the transparent protective layer 1 can directly form a texture structure through an embossing process. For example, a mechanical device can be used to perform embossing processing on the light-transmitting layer 2 to form metal embossing, so that the transparent layer 2 can be transparent. The surface of the light layer 2 may exhibit a textured structure with concavities and convexities. In this way, there is no need to superimpose an additional texture layer 4, which simplifies the structure of the housing and reduces the preparation process and process cost of the housing.

To sum up, in the case provided by the embodiment of the present application, the light-transmitting layer 2 itself has a flexible and rich colorful effect. There is no need to superimpose additional color layers to enable the case to achieve color display, which simplifies the structure of the case.
