Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
In one aspect of the present application, a texture transfer master is presented. According to some examples of the present application, referring to fig. 1 and 2 (fig. 2 is a schematic cross-sectional structure along the direction AA' in fig. 1), the texture transfer master 100 has first texture regions 110 and second texture regions 120 alternately spaced apart, the texture transfer master 100 includes first textures 10 and second textures 20, wherein the texture shapes of the first textures 10 and the second textures 20 are not completely the same, the first textures 10 are located in the first texture regions 110 and a portion of the second texture regions 120 (the first textures located in the first texture regions 110 refer to the first textures 10a in fig. 1 and 2, the first textures located in the portion of the second texture regions 120 refer to the first textures 10b in fig. 1 and 2), the second textures 20 are located in the second texture regions 120, and the first textures 10b and the second textures 20 in the second texture regions 120 are spaced apart. Therefore, the texture transfer master mold 100 can be used for forming a texture transfer sub-mold with the same texture shape, the texture transfer sub-mold can be used for forming the effect of combining and superposing various textures through a single UV transfer process, the texture transfer master mold 100 can be used for simply and conveniently preparing a texture layer with rich texture combination and superposition effects, the preparation process is simple, and the production cost can be saved.
The texture transfer master mold may be made of a metal or glass material, the texture transfer master mold may have a texture pattern formed thereon by a processing process such as etching, the texture transfer sub mold may be made of UV glue, and the UV glue may be generally used to transfer the texture pattern of the texture transfer master mold to obtain a UV texture mold having a texture pattern identical to that of the texture transfer master mold, and the UV texture mold may be a texture transfer sub mold, and the texture pattern of the texture transfer sub mold may be subsequently transferred to a product such as a plate material by a UV transfer process, so that a UV texture layer may be formed on the product such as the plate material.
For ease of understanding, the following briefly describes the principle by which the above-described advantageous effects can be achieved by the texture transfer master according to an example of the present application:
as described above, in the existing method for preparing the texture effect of the plate by using the UV transfer printing process, since the texture transfer printing sub-mold usually has only one texture, that is, the primary UV transfer printing process usually can only form one texture effect, in order to achieve the effect of superimposing two textures, two UV transfer printing processes need to be performed by using two texture transfer printing sub-molds, and two coating processes need to be performed, the preparation process is complicated, and the production cost is high; moreover, after the texture layers and the coating layers are superposed, the superposition stress is large, the texture layers are easy to fall off and lose efficacy, and the product yield is low. According to the texture transfer mother die of the present embodiment, the texture transfer mother die has the first texture and the second texture having two different texture shapes, for example, the first texture may be a nano-scale texture, and the second texture may be a micro-scale texture, so that the texture transfer daughter die prepared by using the texture transfer mother die also has a texture pattern identical to the first texture, when the texture layer is prepared by using the texture transfer daughter die through a UV transfer process, a plurality of texture combination superposition effects (a texture effect corresponding to the texture pattern on the texture transfer mother die can be formed on the panel substrate) can be formed through a UV transfer process, the texture layer having a rich texture combination superposition effect can be simply prepared by using the texture transfer mother die, the formed texture layer has a good appearance effect, and the texture layer is not easy to fall off, and the processes of repeatedly transferring UV textures and repeatedly plating optical films are omitted, the preparation process is simple, and the production cost can be saved.
According to some examples of the present application, referring to fig. 1, the texture transfer master 100 has first texture regions 110 and second texture regions 120 alternately spaced apart thereon, the texture transfer master 100 including first textures 10 and second textures 20, wherein the first textures 10 and the second textures 20 are not identical in texture shape, the first textures 10 are located in the first texture regions 110 and a portion of the second texture regions 120, the second textures 20 are located in the second texture regions 120, and the first textures 10b and the second textures 20 in the second texture regions 120 are spaced apart. Specifically, the surface of the master texture transfer mold substrate may be first subjected to a first processing treatment to form a first texture 10 (for example, a nano-scale texture) on the entire surface of the master texture transfer mold substrate, a second working process is then performed on a portion of the surface of the texture transfer master substrate (e.g. the second texture region 120) on which the first texture 10 is formed, a portion of the previously formed first texture 10 is destroyed by the second process, and a second texture 20 (e.g., a micro-scale texture) is formed at the location of the partially destroyed first texture 10, therefore, the second texture region 120 after the second processing includes the first texture 10 and the second texture 20 which are arranged at intervals, and the formed texture transfer master 100 includes first texture regions 110 (i.e., regions having only the first texture 10) and second texture regions 120 (i.e., regions including the first texture 10 and the second texture 20) alternately arranged at intervals. Therefore, the texture transfer master mold 100 having a plurality of texture combination effects can be simply formed by the above method, and a texture layer having an effect of combining and superimposing a plurality of textures can be formed by one UV transfer process using the texture transfer master mold 100.
According to some examples of the present application, the material forming the texture transfer master 100 may include metal or glass. Specifically, the texture transfer master 100 formed of the above-described material has a high hardness, and thus, the first texture 10 and the second texture 20 can be formed easily by performing a plurality of processes, such as the first process and the second process described above, for example, a laser etching process and a machining process, on the texture transfer master 100.
According to some examples of the present application, the texture shapes of the first texture 10 and the second texture 20 are not identical. It should be noted that "texture shape" includes, but is not limited to, texture height, texture pitch, and the like. Specifically, at least one of the grain spacing and the grain height of the first and second grains 10 and 20 may not be identical. Therefore, the texture transfer master 100 formed by combining the first texture 10 and the second texture 20 can have a rich texture combination superposition effect.
In particular, referring to FIG. 2, the texture height H of the first texture 101And the texture height H of the second texture 202May be different, the texture pitch L of the first texture 101And a texture pitch L of the second texture 202May not be the same. More specifically, the texture of the first texture 10 may be nano-scale, and the texture effect of the second texture 20 may be micro-scale, so that the texture effects of the first texture 10 and the second texture 20 do not interfere with each other, a good texture combination superposition effect is achieved, and the formation of the second texture 20 on the basis of the first texture 10 through the second processing process described above is facilitated, that is, the first texture 10 with smaller dimensional accuracy is used as a "base", and the second texture 20 with larger dimensional accuracy is formed on the first texture 10.
Specifically, the texture pitch L of the first texture 101May be 10 to 1000nm, for example, may be 50nm, may be 100nm, may be 200nm, may be 300nm, may be 400nm, may be 500nm, may be 600nm, may be 700nm, may be 800nm, may be 900nm, may be 1 μm, or the like; the texture pitch L of the second texture 202May be 1.5 to 100. mu.m, for example, 3 μm, 5 μm, 10 μm, 20 μm, 50 μm, 60 μm, 80 μm, or the like. Specifically, the inter-texture height H of the first texture 101May be 10-1000nm, such as 50nm, 100nm, 200nm, 300nm, 400nm, 500nm, 600nm, 700nm, 800nm, 900nm, which may be 1 μm, etc.; the texture height H of the second texture 202May be 1.5-100 μm, for example, may be 3 μm, may be 5 μm, may be 10 μm, may be 20 μm, may be 50 μm, may be 60 μm, may be 80 μm, and the like, and thus, the size difference between the first texture 10 and the second texture 20 is large, the texture effects of the first texture 10 and the second texture 20 do not interfere with each other, and a good texture combination superposition effect is obtained.
Specifically, the first texture 10 may be formed by laser processing, the second texture 20 may be formed by a machining method, specifically, the first texture 10 may be a colorful texture with a small texture height and a small texture pitch, the second texture 20 may be a peacock line stripe with a large texture height and a large texture pitch, and the first texture 10 and the second texture 20 are combined, the texture transfer master mold 100 has a good texture effect, a texture layer with a superimposed effect of a combination of a plurality of textures may be formed by a texture transfer sub-mold formed by the texture transfer master mold 100 through a single UV transfer process, a superimposed texture effect does not need to be formed by transferring UV glue and plating films for a plurality of times, a product yield is high, and a production cost is low.
According to some examples of the present application, referring to fig. 3, the first texture 10 may include a first sub-texture 11 and a second sub-texture 12 formed by stitching, which have texture shapes that are not identical. Specifically, referring to the method described above, when the first working process is performed on the surface of the texture transfer master substrate to form the first texture 10, the first sub-texture 11 may be formed on a portion of the surface of the texture transfer master substrate, and the second sub-texture 12 may be formed on the other portion of the surface of the texture transfer master substrate, whereby the first sub-texture 11 and the second sub-texture 12 may be simply formed in a united state. Specifically, the first sub-texture 11 and the second sub-texture 12 do not have the same texture shape, and the first sub-texture 11, the second sub-texture 12, and the second texture 20 formed in the subsequent step do not have the same texture shape, so that the master texture transfer mold 100 having the three texture effects can be simply formed, and a texture layer having the effect of combining and superimposing the three textures can be formed by the master texture transfer mold 100 through a single UV transfer process. Specifically, the first sub-texture 11 and the second sub-texture 12 may be both nano-scale textures, and the first sub-texture 11 and the second sub-texture 12 may not have the same texture shape, and the second texture may be a micro-scale texture, so that the texture transfer master 100 having the three texture effects may be simply formed.
It should be noted that the number of the spliced textures included in the foregoing first texture 10 is not particularly limited, and the first texture 10 may include the foregoing first sub-texture 11 and second sub-texture 12, or may include three, four, and so on spliced textures, which may be designed by those skilled in the art as needed. The master texture transfer mold 100 of the present application has at least the first texture 10 and the second texture 20, and those skilled in the art can form other textures by a third processing or the like on the basis of the second texture 20 as needed, as long as the shape of the formed texture (i.e., at least one of the pitch and height of the texture) of the other textures is not completely the same as the first texture 10 and the second texture 20. Therefore, according to the application, other texture effects can be superposed on the basis of the pre-formed textures by processing the texture transfer female die base body for multiple times, so that the finally formed texture transfer female die 100 can have the effect of combining and superposing multiple textures, the texture transfer sub-die formed by the texture transfer female die 100 can form a texture layer with the effect of combining and superposing the multiple textures through a single UV transfer process, the superposed texture effects do not need to be formed through multiple times of UV glue transfer, multiple times of film coating and the like, the product yield is high, and the production cost is low.
In another aspect of the present application, a method of making the foregoing texture transfer master is provided. According to some examples of the present application, the method produces a texture transfer master having all of the features and benefits of the texture transfer master described above, and will not be described herein. In general, the method can easily prepare the aforementioned texture transfer master having the first texture and the second texture through a plurality of processes.
According to some examples of the present application, referring to fig. 4, the method includes:
s100: providing a stencil substrate
In this step, a template is first provided. Specifically, the template substrate is the aforementioned texture transfer master substrate. Specifically, the material forming the template substrate may include metal or glass. Therefore, the template substrate can be conveniently processed for multiple times in the subsequent steps, such as laser etching processing, mechanical processing and the like, so that the first texture and the second texture with the texture shapes which are not identical are formed.
S200: carrying out first processing treatment on the template substrate to form a first texture
In this step, the surface of the template substrate described above is subjected to a first processing treatment to form a first texture. Specifically, the entire surface of the aforementioned template substrate may be subjected to the first processing treatment to form the first texture. Specifically, the first processing treatment may include a laser etching treatment or the like, whereby the first texture of a nanometer order may be easily formed on the surface of the template substrate by the first processing treatment.
Specifically, as described above, the first texture formed through the first process may include the first sub-texture and the second sub-texture having the texture shapes that are not identical, and the first sub-texture and the second sub-texture form the stitched texture on the entire surface of the template substrate. Therefore, the texture effect of the prepared texture transfer master mold can be further enriched.
S300: performing second processing treatment on the part of the surface of the template substrate on which the first texture is formed to form a second texture
In this step, a second working process is performed on the portion of the surface of the template substrate on which the first texture is formed, so as to form a second texture. Specifically, as described above, the second processing treatment may be performed on the second texture region of the template substrate, and specifically, the second processing treatment may include a machining treatment or the like, whereby the second texture of a micrometer scale may be simply formed on the basis of the first texture by the second processing treatment. Therefore, the method can form the first texture and the second texture with the same texture shape, the texture transfer master die prepared by the method has the effect of combining and superposing multiple textures, the texture transfer sub-die formed by the texture transfer master die can form a texture layer with the effect of combining and superposing multiple textures through a single UV transfer process, the superposed texture effect does not need to be formed through multiple UV glue transfer and multiple film coating, and the like, so that the product yield is high, and the production cost is low.
In yet another aspect of the present application, a texture transfer sub-mold is presented. According to some examples of the present application, the texture transfer daughter mold is transferred to the previously described texture transfer master mold using UV glue, and in particular, the texture transfer daughter mold has a first texture and a second texture identical to the previously described texture transfer master mold. Thus, the texture transfer sub-mold has all the features and advantages of the texture transfer master mold described above, and will not be described herein again. Generally speaking, the texture transfer sub-mold can form the effect of combining and superposing various textures through a one-time UV transfer process, the texture transfer sub-mold can be used for simply and conveniently preparing texture layers with abundant texture combination and superposition effects, the preparation process is simple, and the production cost can be saved.
In yet another aspect of the present application, a panel is presented. According to some examples of the present application, the texture layer in the plate material may be formed by a single UV transfer process using the texture transfer mold described above, so that the plate material has all the features and advantages of the texture layer prepared by the texture transfer mold described above, and thus the description thereof is omitted. According to some examples of the present application, referring to fig. 5, a sheet 1000 includes a substrate 200, a texture layer 300 and a coating layer 400, the texture layer 300 is disposed on one side of the substrate 200, the coating layer 400 is disposed on one side of the texture layer 300 away from the substrate 200, wherein the texture layer 300 has third texture regions and fourth texture regions (not shown) alternately disposed at intervals, the texture layer 300 includes third textures and fourth textures (not shown), the shapes of the third textures and the fourth textures are not completely the same, wherein the third textures are located in the third texture regions and a portion of the fourth texture regions, the fourth textures are located in the fourth texture regions, and the third textures and the fourth textures in the fourth texture regions are spaced apart. Therefore, the board has abundant texture combination and superposition effects, good appearance effect, simple preparation process and capability of saving production cost.
According to some examples of the present application, a specific type of the substrate 200 is not particularly limited, and in particular, a material forming the substrate 200 may include at least one of glass, polyethylene terephthalate, polycarbonate, and polymethyl methacrylate. Specifically, when the substrate 200 is formed as a glass substrate or a plastic substrate, and the like, after the decorative effects such as the texture layer 300, the coating layer 400, and the like are formed on the substrate 200, the sheet 1000 may be directly used for manufacturing a housing of an electronic device; specifically, when the substrate 200 is a film, for example, a polyethylene terephthalate (PET) film, after forming a decorative effect such as a texture layer 300 and a plating layer 400 on the substrate 200, the sheet 1000 (i.e., the decorative film) may be attached to a surface of a housing substrate (e.g., glass, plastic, etc.) and further used to form a housing of an electronic device.
It should be noted that the texture layer 300 of the plate 1000 can be formed by a single UV transfer process using the texture transfer sub-mold as described above, so that the texture pattern of the texture layer 300 corresponds to the texture pattern of the texture transfer sub-mold as described above (i.e., the texture has the same shape and the protrusions and the depressions of the texture are opposite, i.e., the protrusions of the texture on the texture transfer sub-mold correspond to the depressions of the texture in the texture layer, and the depressions of the texture on the texture transfer sub-mold correspond to the protrusions of the texture in the texture layer).
