With the rapid development of electronic products, portable electronic devices such as mobile phones, tablet computers, and notebook computers have been widely used. With the trend of personalization, people have made higher demands on the appearance of portable electronic devices, particularly mobile terminals. The metal shell has more beautiful texture, and is more and more widely applied to various electronic devices. In order to meet the signal transmission requirement of electronic equipment, the housing of the mobile terminal cannot be completely formed by metal materials, but a non-metal signal wire needs to be arranged in the housing formed by metal. Therefore, the metal casing cannot obtain the whole visual effect. Or, a non-metal substrate can be adopted, and the metal texture appearance can be obtained through later-stage surface treatment, so that the effects of metal-simulated sandblasting texture and high bright edges can be achieved.
However, the current mobile terminal housing, the preparation method and the mobile terminal still need to be improved.
Disclosure of Invention
The present application is based on the discovery and recognition by the inventors of the following facts and problems:
the inventor finds that the mobile terminal shell with a metal appearance prepared on the basis of the matrix made of the non-metal material generally has the problems of complex preparation process and poor appearance effect of metal texture. The inventor of the present invention has found through extensive research and experiments that, when a metal-like shell is prepared by using a non-metal substrate, the coating for forming the high bright edge effect and the coating for realizing the metal blasting effect are not arranged reasonably, so that the high bright edge and the metal blasting texture of a final product need to share one layer of finish. Therefore, the difference between the high bright edge and the metal blasting texture is not obvious, and two kinds of gloss cannot be really realized. In addition, in the preparation process of the shell, multiple times of painting are required, so that the processes of up-and-down spraying of the wire body and dismounting of the clamp are required, the preparation process is complex, and the production efficiency is seriously influenced.

Thereby, the mobile terminal housing described above can be obtained easily. The method can improve the production efficiency, realize more vivid imitation metal sand blasting texture and high bright edge effect, and reduce the cost.
According to the embodiment of the invention, the vacuum coating layer is formed by a non-conductive vacuum coating process by using a metal material. Therefore, the appearance of the metal bright edge can be realized by utilizing the vacuum coating layer, and the glossiness of the metal bright edge of the mobile terminal shell is favorably improved.
According to the embodiment of the invention, the color layer is formed by the following steps: coating a colored paint layer on the surface of the vacuum coating layer, which is far away from one side of the substrate; and carrying out laser etching treatment on the color paint layer, removing the color paint layer in a preset area so as to form the color layer, and exposing the vacuum coating layer in the preset area. Therefore, the laser etching time and the laser area can be reduced, the production efficiency can be improved, and the cost can be reduced. Moreover, the colored paint layer is removed by laser etching, so that the vacuum coating layer for realizing the metal bright edge and the colored paint layer for realizing the matte effect do not share finish paint, and more vivid metal-like sandblasting texture and high-gloss bright edge effect are realized.
According to an embodiment of the invention, the method further comprises at least one of the following steps: pre-forming a primer layer on the substrate before forming the vacuum coating layer; before the color layer is formed, forming a middle paint layer on the surface of the vacuum coating layer, which is far away from the substrate side in advance; and after the color layer is formed, forming a finish paint layer on the surface of the side, away from the substrate, of the color layer.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
In one aspect of the present invention, the present invention provides a mobile terminal case, referring to fig. 1, including: a substrate 100, a vacuum coating layer 200 and a color layer 300. The vacuum coating layer 200 is arranged on the substrate 100, the color layer 300 is arranged on the surface of the vacuum coating layer 200 far away from the substrate 100, and the color layer 300 covers part of the surface of the vacuum coating layer 200. The vacuum evaporation layer 200 may be formed of a vacuum evaporation metal material, so as to provide a high bright edge effect for the mobile terminal housing, and the color layer 300 may obtain a visual effect simulating metal sandblasting texture or ceramic texture by adjusting a color paint forming the color layer 300. According to the embodiment of the invention, the color layer 300 covers part of the surface of the vacuum coating layer 200, so that the position of the mobile terminal housing where the color layer 300 forms the matte effect can be adjusted by adjusting the arrangement position of the color layer 300, such as the coverage area, the shape of the color layer 300 and the like. And the position not covered by the color layer 300 can expose the vacuum coating layer 200, thereby obtaining the effect of metallic highlight. For example, the covering position of the color layer 300 can be controlled to expose the vacuum coating layer 200 in a predetermined area, thereby forming a high bright edge or a metal trademark pattern. This mobile terminal casing can realize more lifelike imitative metal sandblast feel and metal highlight effect, and the contrast of the dull effect of light that obtains is showing more.
The following describes the structure of each layer of the mobile terminal housing according to an embodiment of the present invention:
according to an embodiment of the present invention, the specific type of the base 100 is not particularly limited as long as the design requirements of the mobile terminal housing can be satisfied. For example, it may be a plastic material.
According to an embodiment of the present invention, the vacuum plating layer 200 is formed of a metal material. Thus, the vacuum coating layer 200 can be used to form a metallic highlight visual effect. According to an embodiment of the present invention, a specific formation manner of the vacuum plating layer 200 is not particularly limited, and for example, according to an embodiment of the present invention, the vacuum plating layer may be formed by evaporating a metal target on the substrate 100 using, but not limited to, non-conductive vacuum evaporation (NCVM). As will be understood by those skilled in the art, the metal material forming the vacuum coating layer 200 is a metal target material used in the NCVM. The specific type of the metal target is not particularly limited, and according to an embodiment of the present invention, the metal material includes at least one of indium and indium-tin alloy. The inventor finds that when the metal material is adopted to prepare the vacuum coating layer 200, the signal transmission function of the mobile terminal shell is not negatively influenced. For example, according to an embodiment of the present invention, the vacuum plating layer 200 may be formed using indium having a purity of 99.99 wt%, and the deposition mass may be 3.5 to 4.0 g. The inventors have found through a lot of experiments that when the quality of the evaporated metal material is in the above range, the vacuum coating layer 200 formed has a better metallic luster. Specifically, for the mobile phone shell with most sizes, the vacuum coating layer 200 formed in the range by the evaporation quality can have a proper thickness, so that the waste of the target material can be avoided due to the over-thick thickness of the vacuum coating layer 200, and the metal appearance of the vacuum coating layer 200 can not be influenced due to the insufficient thickness of the vacuum coating layer 200.
According to an embodiment of the present invention, referring to fig. 2, in order to further improve the appearance effect and durability of the mobile terminal case, according to an embodiment of the present invention, the mobile terminal case may further include a primer layer 400. According to an embodiment of the present invention, the primer layer 400 is disposed between the substrate 100 and the vacuum coating layer 200. The primer layer 400 can cover surface flaws of the substrate 100 and enhance adhesion of the vacuum coating 200, serving as a carrier of the vacuum coating 200. Therefore, the durability of the mobile terminal shell can be improved, and the vacuum coating layer is prevented from being peeled off in the using process. According to an embodiment of the present invention, the material forming the primer layer 400 is not particularly limited as long as it can cover surface flaws of the substrate 100 and enhance adhesion of the substrate 100 to the vacuum plating layer 200. For example, the primer layer 400 may be formed using 15 to 25 wt% of ethyl propionate, 65 to 75 wt% of a polyurethane resin, and 5 to 15 wt% of acrylic. Primer layer 400 may be transparent.
According to an embodiment of the present invention, the color layer 300 may be formed by spraying a color paint. For example, according to an embodiment of the present invention, the color layer 300 has a metallic matte appearance or a ceramic white texture. For example, according to an embodiment of the present invention, the color layer 300 can achieve the effect of imitating the texture of metal blasting. Therefore, the color layer 300 can be selected individually, and the appearance effect of the mobile terminal shell can be further improved. The specific type of the material of the color layer 300 is not particularly limited as long as the above-described appearance effect can be exerted. For example, the color layer 300 may be disposed at the center of the mobile terminal case, so that a case panel having a metal blasting feeling may be obtained. The degree of matte appearance presented by color layer 300 can be adjusted by varying the composition of the colored paint making up color layer 300. Specifically, the colored paint constituting the color layer 300 may be composed of 15-25 wt% of alkyd resin, 35-45 wt% of acrylic resin, 5-15 wt% of epoxy resin, 3-7 wt% of resin-coated aluminum sheet, 8-12 wt% of phenetole, 10-20 wt% of butanone, and the like.
According to an embodiment of the present invention, referring to fig. 2, in order to further improve the appearance effect of the mobile terminal housing, according to an embodiment of the present invention, the mobile terminal housing may further include a middle paint layer 500 and a top paint layer 600.
According to an embodiment of the present invention, the intermediate paint layer 500 is disposed between the vacuum coating layer 200 and the color layer 300. The specific type of the material of the middle paint layer 500 is not particularly limited as long as the vacuum plating layer 200 can be protected and laser etching can be facilitated. For example, the middle paint layer 500 may be composed of 15 to 25 wt% of ethyl propionate, 65 to 75 wt% of urethane resin, and 5 to 15 wt% of acrylic. Therefore, the effect of utilizing laser etching can be improved, and the influence on the appearance effect of the exposed vacuum coating layer 200 due to the fact that the color layer 300 is remained because of incomplete laser etching is prevented.
According to an embodiment of the present invention, the topcoat layer 600 is disposed on a surface of the color layer 300 on a side away from the vacuum coating layer 200. Thus, the topcoat layer 600 may be utilized to protect an underlying coating (e.g., color layer 300). According to an embodiment of the present invention, the specific type of the material of the topcoat layer 600 described above is not particularly limited. For example, the topcoat layer 600 may be composed of 20-30 wt% of ethyl butyrate, 55-70 wt% of polyurethane resin, and 10-20 wt% of acrylic acid.
The inventor unexpectedly finds that by adopting the mobile terminal shell according to the embodiment of the invention, the production steps can be simplified, and the production cost can be saved. Specifically, in order to realize the matte effect, the traditional mobile terminal shell generally adopts the color layer arranged on the base body and then the vacuum coating layer is arranged. Specifically, a primer layer and a color layer are sequentially sprayed on the surface of the substrate, and then a vacuum coating layer is arranged. The surface of the substrate portion is then printed with ink to use the printed ink as a mask for removing the vacuum coating. And then spraying deplating liquid on the surface of the substrate printed with the printing ink for deplating treatment, so that the color layer which is not covered by the printing ink in the substrate is exposed outside, thereby realizing the visual effect of metal sand blasting, and the vacuum coating layer is reserved on the part without deplating to form the effect of high gloss edge. And then, spraying the film removing liquid on the surface of the shell for film removing treatment, so that the ink printed on the surface of the matrix is dissolved. And finally, spraying a middle paint layer and a finish paint layer on all the surfaces of the structure for protection. The contrast can know that the operation of spraying the line body from top to bottom needs to be carried out many times to this kind of mobile terminal casing, and relates to dismouting anchor clamps (when spraying printing ink layer or intermediate coat layer) many times. Thereby, the production efficiency of the mobile terminal case is seriously affected. In addition, since a general mobile terminal housing adopts a decoration strategy that the panel has a metal sand blasting effect and a metal highlight edge, the above structure needs to remove the vacuum coating layer on the panel (i.e. the central portion of the substrate) by a method such as laser etching. The area of the panel is obviously larger than that of the bright edge, so that waste of materials of the vacuum coating layer is caused on one hand, and on the other hand, the laser etching area is large, so that the working hours required by the laser etching are prolonged.
In addition, since the color layer and the vacuum coating layer are exposed by the above structure, after the ink layer is removed, the color layer and the vacuum coating layer are protected by additionally arranging the middle paint layer and the finish paint layer. The two-layer structure shares the middle paint layer and the finish paint layer, so that a real matte effect cannot be obtained, namely the contrast between the metal bright edge and the metal sand blasting effect is not obvious enough.
As described above, according to the mobile terminal housing of the embodiment of the present invention, since the positions of the vacuum coating layer 200 and the color layer 300 are designed, the vacuum coating layer 200 and the color layer 300 are prevented from sharing a topcoat layer, so that the contrast of the matte effect between the vacuum coating layer 200 and the color layer 300 can be greatly improved. Moreover, the inventors have surprisingly found that when the color layer 300 is disposed on the vacuum coating layer 200, the laser etching area of the laser etching process can be greatly reduced. Therefore, the waste of materials can be saved, and the laser etching processing time is reduced. In addition, this structure has avoided spraying the ink layer or the intermediate coat layer many times to can reduce the operation of spraying the line body from top to bottom, and then can improve production efficiency.
According to the specific embodiment of the invention, the matte brightness of the mobile terminal shell is tested, and the test result shows that the metal highlight (smooth surface) and matte effect (matte surface) brightness difference is large according to the embodiment of the invention, so that the appearance effect with obvious contrast can be realized. Specifically, the brightness of the smooth surface and the matte surface of the mobile terminal shell is tested by adopting a German BYK miniature three-angle gloss meter (model 4446). Referring to fig. 2, the brightness of the points a and B was measured at 3 different incident angles, and the results are shown in table 1. In contrast, when the incident angle was the same, the luminance of the light surface (point B) was significantly higher than that of the matte surface (point a).
TABLE 1
In another aspect of the invention, the invention proposes a method of manufacturing a mobile terminal housing as described above. According to an embodiment of the invention, referring to fig. 3, the method comprises:
s100: forming a vacuum coating layer
According to an embodiment of the present invention, in this step, a vacuum plating layer is formed on the substrate. According to the specific implementation of the invention, the vacuum coating layer can be formed by a non-conductive vacuum coating process by utilizing a metal material. Therefore, the appearance of the metal bright edge can be realized by utilizing the vacuum coating layer, and the glossiness of the metal bright edge of the mobile terminal shell is favorably improved. The specific materials for forming the vacuum coating layer and the substrate have been described in detail above, and are not described in detail here. For example, according to an embodiment of the present invention, the process conditions of vacuum coating may be: the working vacuum degree is 5.0X 10-2Pa, vacuum degree of coating film of 8.0 × 10-1Pa, evaporation power of 10-12kw, and coating time of 8-10 s. The coating material may be 99.99% indium, 3.5-4.0g by mass.
In order to further improve the vacuum coating effect, according to an embodiment of the present invention, before forming the vacuum coating layer, referring to fig. 4, the method may further include:
s10: forming a primer layer
According to an embodiment of the present invention, in this step, a primer layer is first formed on the surface of the substrate. Therefore, the surface flaws of the substrate can be covered, the adhesive force of the vacuum coating can be enhanced, and the function of a carrier of the vacuum coating layer can be achieved. Therefore, the durability of the mobile terminal shell can be improved, and the vacuum coating layer is prevented from being peeled off in the using process. The specific material of the primer layer has been described in detail above, and is not described in detail here. The specific method of forming the primer layer and the operating parameters are also not particularly limited and may be adjusted by those skilled in the art according to the actual circumstances. For example, according to a specific embodiment of the present invention, the primer layer may be formed by spraying a transparent primer. Specifically, a colorless and transparent primer can be sprayed by using an automatic compressed air spraying technology. Subsequently, spraying on the baseAnd (4) performing film forming treatment on the primer on the body. The film forming conditions can be that the leveling time is 3-5min, the baking temperature is 50-55 ℃ and the time is 4-6 min. Subsequently, a UV curing treatment is performed, the energy of the UV curing treatment may be 700-2The viscosity of the paint may be 7.5-8.5s (NK-2, sec/25C) (using a rock NK-2 cup, the time for paint to flow through the cup at 25C is 7.5-8.5 s). The film thickness of the formed primer layer may be 12 to 20 μm.
S200: forming a color layer
According to an embodiment of the invention, in this step, a color layer is formed on the side of the vacuum coating layer away from the substrate, and the color layer covers part of the surface of the vacuum coating layer. The materials, functions, positions and appearance effects of the color layers are described in detail above, and will not be described in detail herein. The specific method for forming the color layer is also not particularly limited, and for example, the color paint material for forming the color layer may be sprayed on the surface of the vacuum-coated layer by using an automatic compressed air spraying technique. For example, according to an embodiment of the present invention, the sprayed paint may be a silver paint material having a metallic frosting effect. It will be appreciated by those skilled in the art that after the paint is sprayed, it may be subjected to a film forming process. The film forming condition can be that the leveling time is 4-6min, the baking temperature can be 75-85 ℃ and the time is 10-15 min. The viscosity of the lacquer may be 8.5-9.5s (NK-2, sec/25 ℃ C.). The film thickness of the finally formed color layer may be 4 to 8 μm.
According to an embodiment of the present invention, referring to fig. 5, forming the color layer may be achieved by:
s1: applying a layer of colour paint
According to an embodiment of the invention, in this step, a color paint is applied to the surface of the vacuum-coated layer on the side remote from the substrate. The specific operating parameters for applying the pigmented paint layer have been described in detail above and will not be described in detail here.
S2: carrying out laser etching treatment on the colored paint layer
According to the embodiment of the invention, in the step, the color paint layer is subjected to laser carving treatment, the color paint layer in the preset area is removed, so that the color layer is formed, and the vacuum coating layer in the preset area is exposed. Specifically, a circle of color layer at the edge of the substrate is removed, so that the vacuum coating layer at the edge can be exposed to form a metal bright edge. Or, the colored paint layer with a certain shape can be removed in the center of the base body by arranging the laser filling area of the laser engraving, and the exposed vacuum coating layer is utilized to form a metallic trademark pattern in the center of the base body, so that the arrangement of trademark hardware can be saved. Therefore, the laser etching processing time and the laser area can be reduced, the production efficiency is improved, and the cost is reduced. The specific parameters of the laser etching process are not particularly limited, and those skilled in the art can select the parameters according to actual situations. For example, the laser etching conditions may be as follows: the frequency is 8000-.
According to an embodiment of the present invention, in order to further improve the effect of vacuum coating, before forming the color layer, referring to fig. 4, the method may further include:
s20: formation of the intermediate paint layer
According to the embodiment of the invention, before the color layer is formed, the intermediate paint layer can be formed on the surface of the vacuum coating layer on the side far away from the substrate in advance. The materials and functions of the intermediate paint layer have been described in detail above, and are not described in detail here. For example, according to embodiments of the present invention, the midcoat layer may be formed by spraying a transparent protective midcoat using an automatic compressed air spraying technique. After the intermediate coat is sprayed, the intermediate coat may be subjected to a film forming process. The film forming condition is that the leveling time is 3-5min, the baking temperature can be 50-55 ℃, and the time is 4-6 min. Subsequently, it may be subjected to a UV curing treatment. The energy for curing can be 500-600mj/cm2The viscosity of the paint was 7.5-8.5s (NK-2, sec/25 ℃ C.). The film thickness of the finally formed intermediate coat layer may be 12 to 18 μm. Therefore, the effect of utilizing laser etching can be improved, and the influence on the appearance effect of the exposed vacuum coating layer due to the fact that the color layer is remained because of incomplete laser etching is prevented.
S30: forming a topcoat layer
According to the embodiment of the present invention, after the color layer is formed, a finishing paint layer may be formed on a surface of the color layer on a side away from the substrate. Therefore, the color layer can be protected by the finish paint layer, so that the performance of the mobile terminal shell prepared by the method can be further improved. The specific materials for the topcoat layer have been described in detail above and will not be described in detail here. According to embodiments of the present invention, the topcoat layer may be formed by spraying the topcoat using an automatic compressed air spraying technique. The protective topcoat can be colorless and transparent, and thus, does not affect the appearance of the color layer below the topcoat layer. After the finish paint is sprayed, film forming treatment can be carried out on the protective finish paint under the conditions of leveling time of 3-5min, baking temperature of 50-55 ℃ and time of 4-6 min. Subsequently, it may be subjected to a UV curing treatment, and the energy may be 800-2The viscosity of the formed topcoat layer may be 7.5 to 8.5s (NK-2, sec/25 ℃ C.), and the film thickness is 20 to 30 μm.
As will be appreciated by those skilled in the art, when the method includes the step of providing a topcoat layer, and with reference to fig. 6, forming the color layer may be accomplished by:
