With the progress of science and technology and the improvement of living standard, terminal devices such as mobile phones and tablet computers are more and more popular. In order to improve the cruising ability, the capacity of a battery in the terminal equipment is larger and larger, and the space occupied by the battery is also larger and larger, so that the thickness of the terminal equipment is larger.
In the related art, in order to provide a thin visual effect to a user, a color separation mode is generally adopted on the housing to visually weaken the characteristic of large thickness of the terminal device. In the related art, the color separation is performed in such a manner as: anodizing twice on the shell made of the set material, forming a first color on the surface of the whole shell by anodizing for the first time, etching part of a first color area, and anodizing for the second time after shielding by adopting exposure and development ink or glue, thereby realizing a bicolor visual effect.
However, in the above-described related art, there are the following technical problems: at the boundary of the bicolor region obtained by two times of anodic oxidation, due to the thickness difference of the anode film and the shielding of acid seepage, white edges, saw teeth, wavy lines, character broken lines and other problems are easy to form, and the delicacy of the appearance of the shell is influenced.
In an exemplary embodiment, as shown in fig. 1, the present embodiment proposes a dyeing method, which may specifically include the following steps:
and S110, carrying out anodic oxidation treatment on the substrate to form an anodic oxidation layer on the surface of the substrate.
The base 10 may be a substrate made of metal, such as an aluminum alloy substrate. After the surface of the substrate 10 is anodized, as shown in fig. 2, an anodized layer 100 with micropores 101 is formed on the surface of the substrate 10. The shape and size of the nano-pores 101 can be controlled by adjusting the voltage, for example, the pore diameter of the nano-pores 101 can be 15nm to 50 nm.
In this step, as shown in fig. 3, the anodized layer 100 includes a first region 110 and a second region 120. The first region 110 and the second region 120 may, for example, be different local regions of the surface of the substrate 10, in order to achieve different colors in the first region 110 and the second region 120 in the subsequent processing.
After this step, the substrate 10 may be subjected to a drying process to dry the moisture of the substrate 10. The drying temperature can be 60-80 ℃, and the drying time can be 45-120 minutes. Step S120 is performed after the drying process.
And S120, filling nano materials in the nano micropores in the first area of the anodic oxidation layer by adopting a printing process.
The printing process may be, for example, pad printing, silk-screen printing, printing or the like, and the printing process may only print the predetermined shape or area. The nanomaterial may be, for example, a colorless, monochromatic, or polychromatic (colored) polymer nanomaterial, for example, butyl glycolate, 1-methoxy-2-propanol, or other nanopigments are used.
Taking a silk-screen printing mode as an example: placing the screen plate with the pattern on the surface of the anodic oxide layer to shield the second area, wherein the pattern can correspond to the shape of the first area; and printing the nano material on the surface of the screen plate so as to fill the nano micropores in the first area in a targeted manner. The screen plate can realize the shielding effect in the area except the area corresponding to the first area, and can print in the position corresponding to the first area. And filling the nano material into the nano micropores in the first region by using a screen printing scraper (for applying pressure) and the adsorption force of negative ions in the polymer nano material and positive ions of the metal material.
In this step, as shown in fig. 3 to 4, nanoparticles may be filled in the nano-pores 101 of the first region 110 through a printing process, so that the color of the nano-material 20 is presented in the first region 110, and the printed form is as shown in fig. 3 or fig. 6. The thickness of the printing may be, for example, 1um to 8um, i.e., the thickness of the nanoparticles extending in the nano-pores 101 is 1um to 8 um.
The color exhibited by the first region 110 may be, for example, a plurality of colors depending on the color of the nanomaterial 20.
In one example, to render the first region 110 multi-colored, multi-colored nanomaterials 20 may be employed. The polychromatic nanomaterial 20 may be, for example: the nano-materials 20 of two colors are mixed in advance to form the multi-color nano-material 20. Printing with the multi-colored nanomaterial 20 causes the first region 110 to appear multi-colored.
In another example, to make the first region 110 appear multi-color, the nano-materials 20 with different colors may be printed in several times. Such as: a first portion of the first region 110 is printed with a first color of nanomaterial 20 and a second portion of the first region 110 is printed with a second color of nanomaterial 20. Thereby, a multicolor effect is achieved in the first region 110.
After this step, the printed substrate 10 may be subjected to a baking treatment under the following conditions: 50-80 ℃ for 10-30 minutes. Step S130 is performed after the baking process.
And S130, dyeing the anodic oxidation layer to fill the nanometer micropores in the second area of the anodic oxidation layer with pigment particles.
Wherein the color of the nanomaterial 20 is different from the color of the pigment particles 30.
In this step, the entire anodized layer is further dyed in addition to the printing in step S120. As shown in fig. 3 to 4, since the nano-pores 101 in the first region 110 are filled with the nanoparticles, the pigment particles cannot be refilled into the pores of the first region, and even if some nanoparticles are attached, only the nanoparticles are attached to the surface of the filled nanoparticles, and the nanoparticles are not as firm as the pores directly dyed, and have a step difference (height difference) in height with the pigment of the second region, and are easily peeled off (first contacting with the grinding wheel) during polishing, and are separated from the nanoparticles, so the pigment particles 30 are filled into the nano-pores in the second region 120, and are dyed or sealed, so that the color of the pigment particles 30 appears in the second region 120. The dyed form is shown in FIG. 4 or FIG. 7.
In addition, after the second region 120 is dyed, the nano-pores in the second region may be sealed to enclose the pigment examples in the nano-pores. Thereby avoiding the second area 120 from fading, discoloring, etc. during use.
In the embodiment of the present disclosure, the integral anodized layer is formed once through the step S110, and then at least two color effects are formed in the first region 110 and the second region 120 respectively through the printing of the step S120 and the dyeing of the step S130, so that the connection between the two color regions is more natural, and white edges, saw teeth, wavy lines, broken character lines, and the like are not formed. Therefore, the whole basal body 10 can realize multicolor effect, the appearance delicacy is kept, and the phenomenon that the interface line is not colored and white lines appear in a double-color area formed by two times of anodic oxidation due to the thickness difference of the anode film and the shielding of the acid seepage is avoided.
In an exemplary embodiment, the first region may be disposed in various manners. In this embodiment, the first region includes at least one sub-region.
In one example, the first region comprises one sub-region. After printing, a monochrome, colorless or multicolor effect can be formed in the sub-area and distinguished from the color of the second area.
In another example, the first region includes two or more sub-regions, and different sub-regions are spaced apart. After printing, a single color, colorless or multicolor effect can be formed in a plurality of spaced sub-areas respectively. In combination with the color of the second area, a multi-colored visual effect is further achieved.
In this example, the spacing region between the different sub-regions, which is a part belonging to the second region, may be dyed to form a color different from that of the sub-regions.
In an exemplary embodiment, before step S110, the dyeing method of the present embodiment further includes the steps of:
s100, performing at least one of the following treatments on the base material to obtain a matrix: shape processing, polishing treatment and cleaning.
The substrate may be a metal material, for example. The following description will be made by taking an aluminum alloy base material as an example:
in this step, the aluminum alloy base material may be first subjected to shape processing. CNC (numerical control mechanical precision machining) processing is carried out on the base material so as to meet the appearance requirement of product design. For example, when the base is used to form a housing for a terminal device, the substrate may be CNC machined to form the housing as shown in fig. 5.
After the shape is processed, the aluminum alloy matrix with the preset shape can be polished, so that the surface of the matrix can achieve the highlight effect.
After the polishing treatment, the aluminum alloy substrate may be cleaned. The cleaned substrate is ready for use and is ready for step S110.
In an exemplary embodiment, after step S130, the dyeing method of the present embodiment further includes the steps of:
and S140, polishing the anodic oxide layer.
Wherein, after the printing of step S120 and the dyeing of step S130, the nano-pores of the anodic oxide layer are filled and sealed by the nano-material 20 or the pigment particles 30.
In this step, the substrate after anodic oxidation hole sealing can be polished by using a cloth wheel and matching with polishing wax (or polishing solution).
The embodiment is used for removing the oxidation floating dust on the surface of the anodic oxidation layer or the substrate and the redundant nano coating outside the nano micropores, so that the surface of the bicolor or multicolor substrate has a bright effect.
In an exemplary embodiment, the present disclosure also provides a shell, which is prepared by using any one of the above dyeing methods. The housing can be used, for example, in a terminal.
In an exemplary embodiment, the embodiment of the present disclosure further provides a housing, as shown in fig. 2 to 7, including a substrate 10 and an anodized layer 100 disposed on a surface of the substrate 10, where the anodized layer 100 is covered with nano-pores 101, and the anodized layer 100 includes a first region 110 and a second region 120.
In this embodiment, the nano-pores 101 of the first region 110 are filled with the nano-material 20, wherein the nano-material 20 enters the nano-pores 101 through a printing process. The nano-pores of the second region 120 are filled with pigment particles 30, wherein the pigment particles 30 enter the nano-pores 101 through a dyeing process. The nanomaterial 20 is a different color than the pigment particles 30.
In the embodiment of the disclosure, the integral anodic oxidation layer can be formed at one time, then at least two color effects are respectively formed in the first area and the second area through printing and dyeing, the connection between the two color areas is more natural, and white edges, sawteeth, wavy lines, character broken lines and the like cannot be formed. Therefore, the whole matrix can realize multicolor effect and keep the appearance delicate.
In one exemplary embodiment, the nanomaterial is a colorless nanomaterial or a colored nanomaterial.
In this embodiment, the color nano material is a single-color nano material or a multi-color nano material.
