Detailed Description
Embodiments of the present application are described in detail below. The following examples are illustrative only and are not to be construed as limiting the application. The examples are not to be construed as limiting the specific techniques or conditions described in the literature in this field or as per the specifications of the product.
In one aspect of the application, a housing is provided. According to an embodiment of the present application, referring to fig. 1, the housing includes: a base material 10; a first texture layer 21, the first texture layer 21 being disposed on one surface of the substrate; the first coating layer 31, the first coating layer 31 is disposed on one side of the first texture layer 21 away from the substrate 10; the second texture layer 22, the second texture layer 22 is set up in the first coating layer 31 far away from one side of the substrate 10; the second coating layer 32, the second coating layer 32 is disposed on a side of the second texture layer 22 away from the substrate 10, wherein the reflectivity of the second coating layer 32 is greater than that of the first coating layer 31. Therefore, the shell structure has double textures and double coating films, the superposition of the double textures can be realized, and users can see different texture effects under different angles, so that the appearance textures are richer in layering and stereoscopic impression, the expression effect is better, and the appearance effect and the visual effect of the shell are further enriched; in addition, the reflectivity of the second coating layer 32 is greater than that of the first coating layer 31, the reflective effect of the second coating layer 32 is stronger, and the texture effect of the second texture layer can be effectively ensured to be supported by the lining, so that the textures of the second texture layer are prevented from being covered by the first coating layer.
It should be noted that, in the use of the casing, the surface of the substrate 10 far from the first texture layer 21 is an appearance surface, that is, the first texture layer 21 is close to the appearance surface, and the second texture layer 22 is far from the appearance surface, so that the textures of the first texture layer 21 and the second texture layer 22 are different in depth in vision, so that the appearance texture is more layered and stereoscopic.
Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Wherein the thickness of the base material is 0.5 mm-0.64 mm (such as 0.5mm, 0.55mm, 0.6mm and 0.64 mm). Therefore, the base material with the thickness has good supporting effect and strength, and then effectively resists external impact forces such as external collision and the like; if the thickness of the base material is larger, the whole thickness of the shell is relatively thicker; if the thickness of the base material is smaller, when structures such as a texture layer and the like are prepared on the base material, the supporting force and the strength of the base material are relatively deviated, so that the preparation of the texture layer and the coating layer with better quality is not facilitated.
Wherein, icons (such as LOGO) are arranged on the surface of the substrate near the first texture layer, and the method for forming the icons includes but is not limited to silk screen printing.
Further, the specific material of the substrate is not particularly required, and those skilled in the art can flexibly select the specific material according to practical situations. In some embodiments, the material of the substrate is at least one of PET (polyethylene terephthalate), PC (polycarbonate) and PMMA (polymethyl methacrylate), such as a PMMA/PC composite board, wherein LOGO, etc., is silk-screened on the surface of PC, and PMMA is used as the appearance surface.
The first coating layer is an optical coating layer, so that the first coating layer can have good reflectivity and good light transmittance, and can set off the texture effect of the first texture layer and can not shield the texture effect of the second texture layer.
Further, the second coating layer may be an indium tin coating layer or an optical coating layer, and the reflectivity of the second coating layer and the reflectivity of the first coating layer of different materials are described in detail below:
in some embodiments, the second coating is an indium tin coating, and the first coating has a reflectivity of 8% -40% (e.g., 8%, 10%, 15%, 20%, 25%, 30%, 35%, 40%), and the indium tin coating has a reflectivity of greater than 40%. Therefore, the reflectivity of the indium tin coating layer is relatively large, the light reflection effect is strong, the texture effect of the second texture layer can be well supported, and the texture effect is not shielded by the first coating layer and the first texture layer, so that a user can clearly see the texture pattern of the second texture layer, and if the transparent color layer is further arranged on one side of the first coating layer far away from the first base material, the indium tin coating layer with the reflectivity can also effectively prevent the color layer from being shielded by the first coating layer and the first texture layer, and the color expressive force of the transparent color layer is improved; if the reflectivity of the first coating layer is less than 8%, the texture pattern of the first texture layer may not be obvious or clear.
The thickness of the indium tin coating layer is 40 nm-60 nm, such as 40nm, 42nm, 44nm, 46nm, 48nm, 50nm, 52nm, 54nm, 56nm, 58nm and 60nm. Therefore, the indium tin coating layer with the thickness has better reflectivity, so that the texture effect of the second texture layer is good, and if the transparent color layer is further arranged on one side of the first coating layer far away from the first base material, the indium tin coating layer with the thickness can also effectively prevent the color layer from being covered by the first coating layer and the first texture layer, so that the color expressive force of the transparent color layer is improved; if the thickness is less than 40nm, the light-emitting effect (reflectivity) of the indium tin coating layer is relatively poor, and the second texture layer and the transparent color layer are easily shielded by the first texture layer and the first coating layer; if the thickness is larger than 60nm, the indium tin coating layer is conductive, and the antenna performance of the mobile phone is affected.
In other embodiments, the second coating layer is an optical coating layer, and the first coating layer has a reflectivity of 8% -40% (e.g., 8%, 10%, 15%, 20%, 25%, 30%, 35%, 40%) and the optical coating layer has a reflectivity of 15% -50% (e.g., 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%). Therefore, the texture effect of the first texture layer and the second texture layer has good expressive force, and the texture patterns are clearly visible.
Wherein, the thickness of the first coating layer is 10 nm-60 nm (such as 10nm, 20nm, 30nm, 40nm, 50nm, 60 nm). Therefore, the adhesive force of the first coating layer is better, and the stability is better; if the thickness is less than 10nm, the adhesive force of the first coating layer is relatively poor; if the thickness is larger than 60nm, the first coating layer is easy to crack after subsequent high-pressure hot bending, and the performance of texture effect is affected.
Wherein the thickness of the optical coating layer is 40 nm-200 nm (such as 40nm, 50nm, 60nm, 70nm, 80nm, 90nm, 100nm, 110nm, 120nm, 130nm, 140nm, 150nm, 160nm, 170nm, 180nm, 190nm, 200 nm). Therefore, the optical coating layer has better adhesive force, better stability, difficult cracking and better reflectivity; if the thickness is more than 200nm, the first coating layer is easy to crack after subsequent high-pressure hot bending, and the performance of texture effect is affected.
Further, the specific materials of the first coating layer and the optical coating layer independently include at least one of zirconia, titania, silica, and niobia, so the first coating layer and the optical coating layer may have a single-layer structure or a multilayer laminated structure, where the thickness of each sub-coating layer may be flexibly adjusted according to the actual situation of the required reflectivity, etc., and the following structures of the first coating layer 31 and the optical coating layer (i.e., the second coating layer 32) in some embodiments are listed in table 1 and table 2 (the reflectivity ranges in the range of 500-800 nm for the corresponding wavelength).
TABLE 1 first coating layer
TABLE 2 optical coating layer (i.e., second coating layer 32)
Further, referring to fig. 4 to 6, the housing further includes: a transparent color layer 40, the transparent color layer 40 is disposed between the substrate 10 and the first texture layer 21 (fig. 4), or between the first coating layer 31 and the second texture layer 22 (fig. 5), or on a side of the second coating layer 32 remote from the substrate 10 (fig. 6). Therefore, the shell with double textures and double coating structures can make the depth of field effect (the visual apparent distance) and the stereoscopic impression of the color layer more obvious, further improve the layering sense, expressive force and visual effect of the appearance effect of the shell, and further improve the stereoscopic impression and depth of field effect of the transparent color layer when the transparent color layer 40 is positioned on one side of the first coating layer 31 far away from the substrate 10 (as shown in fig. 5 and 6).
Further, the specific kind of the transparent color layer 40 may be a spray color layer (i.e. a color layer obtained by spraying a transparent paint), or may be an offset color layer (i.e. a color layer obtained by offset UV curing a transparent ink), specifically:
in some examples, the transparent color layer 40 is a spray color layer, where the second coating layer 32 is an indium tin coating layer, and the spray color layer is disposed on a side of the second texture layer 22 away from the indium tin coating layer (i.e., the second coating layer 32) (see fig. 4 and 5). Because the light transmittance of the indium tin coating layer is poor, the spray color layer is not easy to be arranged on one side of the indium tin coating layer 32 far away from the substrate 10, otherwise, the color development effect of the transparent color layer 40 on the appearance surface of the substrate 10 is poor, and even the color of the transparent color layer cannot be seen; and because the thickness of the spraying color layer prepared by spraying is thicker, the color is darker, and the indium tin coating layer with higher reflectivity and better reflecting effect is adopted, the transparent color layer can be better set off, the expressive force of the appearance color of the shell is further improved, and if the optical coating layer is adopted, the color of the transparent color layer is difficult to set off, so that the color distortion of the transparent color layer seen on the appearance surface is serious.
In other examples, the transparent color layer 40 is an offset color layer, and the second coating layer 32 is an optical coating layer or an indium tin coating layer, where when the second coating layer 32 is an indium tin coating layer, the offset color layer (i.e., the transparent color layer 40) is disposed on a side of the second texture layer 22 away from the indium tin coating layer (i.e., the second coating layer 32) (see fig. 4 and 5). Since the offset color layer prepared by offset printing is thin in thickness and generally light in color, the second plating layer 32 may be any one of an optical plating layer and an indium tin plating layer. Since the optical coating layer has better light transmittance, the position of the transparent color layer 40 can be any of the cases shown in fig. 4 to 6 when the second coating layer 32 is an optical coating layer.
Wherein the thickness of the spray color layer is 8-14 microns, such as 8 microns, 9 microns, 10 microns, 11 microns, 12 microns, 13 microns or 14 microns. The offset color layer has a thickness of 5 to 8 microns, such as 5 microns, 6 microns, 7 microns, or 8 microns. The transparent color layer with the thickness can have good color expressive force on the appearance surface of the shell, and the adhesive force of the transparent color layer is better.
According to an embodiment of the present application, the difference between the elongation of the first texture layer and the elongation of the first plating layer is 5% or less, such as 5%, 4.5%, 4%, 3.5%, 3%, 2.5%, 2%, 1.5%, 1%, 0.5%, 0.2%, or 0, etc. Therefore, the difference between the elongation of the first texture layer and the elongation of the first coating layer is small, the elongation shrinkage curvature of the first texture layer and the elongation shrinkage curvature of the first coating layer are similar in the high-pressure hot bending forming process, the stress difference of the first texture layer and the elongation shrinkage curvature of the first coating layer is small, the first texture layer and the elongation shrinkage curvature of the first coating layer are not easy to crack, and the product yield of the shell is improved.
Further, the difference between the elongation of the second texture layer and the elongation of the second coating layer is 5% or less, such as 5%, 4.5%, 4%, 3.5%, 3%, 2.5%, 2%, 1.5%, 1%, 0.5%, 0.2% or 0. Therefore, the difference between the elongation of the second texture layer and the elongation of the second chemical coating layer is small, the elongation shrinkage curvature of the second texture layer and the elongation shrinkage curvature of the second coating layer are similar in the high-pressure hot bending forming process, and the stress difference of the second texture layer and the elongation shrinkage curvature of the second coating layer is small, so that the second texture layer and the elongation shrinkage curvature of the second chemical coating layer are not easy to crack, and the product yield of the shell is improved.
Further, the difference between any two of the elongation of the first texture layer, the elongation of the first coating layer, the elongation of the second texture layer and the elongation of the second coating layer is 5% or less. Therefore, the difference between the extension rates of the four-layer structure is small, the extension shrinkage curvature of the four-layer structure is similar in the high-pressure hot bending forming process, and the stress difference between different structures is small, so that the four-layer structure is not easy to crack, and the product yield of the shell is further improved.
Further, the elongation of the first texture layer and the elongation of the second texture layer are 10% to 50%, such as 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, respectively. Therefore, the first texture layer and the second texture layer are not easy to break, and the texture appearance effect is not easy to influence; if the elongation is less than 10%, the first texture layer and/or the second texture layer is bent and is easy to break; if the elongation is greater than 50%, the film layer becomes uneven easily after the first texture layer and/or the second texture layer is hot bent and stretched, so that rainbow patterns are generated, and finally, the texture effect of the appearance of the shell is affected. Therefore, a person skilled in the art can adjust the elongation percentage of the first coating layer and the second coating layer according to the elongation percentage of the first texture layer and the second texture layer so as to achieve the requirement that the elongation percentage difference is less than or equal to 5%.
It should be noted that, it is well known to those skilled in the art that UV light-curable glue has a high crosslinking density, a high crosslinking functionality, and a high mechanical rigidity, and that the elongation of the texture layer is almost 0 and is easy to stretch and break at normal temperature, so that the elongation of the first texture layer, the second texture layer, the first coating layer, and the second coating layer refers to the elongation of each structure in the high-pressure hot bending process. The test method of the elongation percentage of the texture layer is described in detail by taking the texture layer as an example:
test equipment: TMA instrument (thermo-mechanical analysis instrument)
Test temperature: 135 + -5 deg.C (technological temperature for high-pressure hot bending of the shell)
Test mode: stretching mode
Test purpose: mechanical properties/tensile change/thermal shrinkage/stress release of the test specimens at the test temperature
The testing steps are as follows:
(1) Sample preparation: according to a normally manufactured UV light curing process, placing UV light curing UV glue into a cube vessel for curing and forming to obtain a cube sample;
(2) Sample loading: clamping the sample in a TMA instrument test bracket;
(3) The method comprises the following steps: and selecting a stretching mode, inputting sample information and size, testing at a constant temperature of 135 ℃, outputting original data, and obtaining the elongation of the sample at the testing temperature through data processing.
According to an embodiment of the present application, the shore hardness of the UV glue used to form the first texture layer and the shore hardness of the UV glue used to form the second texture layer are D65 to D90, such as D65, D70, D75, D80, D85, D90, respectively. Therefore, the first texture layer and the second texture layer not only can show good texture effect, but also have better anti-falling performance; if the Shore hardness is less than D65, the UV glue is relatively soft, and the formed first texture layer and second texture layer are easy to deform after high-pressure hot bending, so that rainbow patterns are generated, and the texture effect of the appearance is affected; if the Shore hardness is larger than D90, the UV glue is relatively hard, and the anti-dropping performance of the formed first texture layer and second texture layer is relatively poor.
Further, the thickness of the first and second texture layers is 7 to 13 microns, such as 7 microns, 8 microns, 9 microns, 10 microns, 11 microns, 12 microns, or 13 microns, respectively. Therefore, the first texture layer and the second texture layer have good adhesive force and are not easy to crack; if the thickness is less than 7 microns, the adhesion of the first texture layer and the second texture layer is relatively poor; if the thickness is greater than 13 μm, the first texture layer and the second texture layer are liable to crack when bending.
The specific textures of the first texture layer and the second texture layer are not particularly required, and can be flexibly selected by a person skilled in the art according to practical situations, for example, the specific textures of the first texture layer and the second texture layer respectively and independently comprise but are not limited to various texture patterns such as S texture, oblique line texture, light pillar texture, grid texture, colorful texture, peacock texture and the like. The specific texture patterns of the first texture layer and the second texture layer are different, so that superposition of the two texture patterns can be realized.
According to an embodiment of the present application, referring to fig. 7, 8 and 9, the housing further includes: the first gloss oil layer 50, the first gloss oil layer 50 is disposed on the surface of the first coating layer 31 away from the substrate 10. Therefore, the arrangement of the first gloss oil layer 50 can further improve the flatness and uniformity of the surface of the first coating 31, thereby improving the adhesion of the first coating to other structures. In fig. 7 and 9, the first gloss oil layer 50 is located between the first coating layer 31 and the second texture layer 22, and the first gloss oil layer 50 can promote the flatness and uniformity of the surface of the first coating layer 31, so that the second texture layer 22 and the first coating layer 31 are better attached, the reliability of the shell is improved, and as the first gloss oil layer 50 is located between the first coating layer 31 and the second texture layer 22, no other layer structures such as transparent color layers are arranged, and the arrangement of the first gloss oil layer 5 can also prevent interference between the textures of the first texture layer 21 and the textures of the second texture layer 22, so that the superposition effect of the two textures is more obvious. In fig. 8, if the transparent color layer 40 is an offset color layer, the first gloss oil layer 50 may be disposed to improve the adhesion of the offset color layer (in terms of process, it is generally necessary to screen-print a gloss oil layer before offset printing the transparent color layer to improve the adhesion of the offset color layer); if the transparent color layer 40 is a spray color layer, the first gloss oil layer 50 can be disposed to prevent the paint solvent from eroding into the first texture layer during spraying, so as to ensure a good texture effect of the first texture layer.
Wherein the thickness of the first gloss oil layer 50 is 4-8 microns, such as 4 microns, 5 microns, 6 microns, 7 microns, or 8 microns. Therefore, the first gloss oil layer with the thickness has better adhesive force and is not easy to crack when being bent under high pressure and heat; if the thickness is less than 4 microns; if the thickness is smaller than 4 micrometers, the adhesion is relatively poor, the manufacturing process difficulty is high, and in fig. 7 and 9, the interference effect between the two textures of the first texture layer 21 and the second texture layer 22 cannot be well avoided by the thinner first gloss oil layer 50, and in fig. 8, the texture effect of the first texture layer is affected by the fact that the thinner first gloss oil layer 50 is easy to erode a color paint solvent into the first texture layer when spraying the color paint; if the thickness is greater than 8 μm, the first gloss oil layer 50 is easily broken when it is thermally bent.
Further, if the transparent color layer 50 is an offset color layer and the setting position is shown in fig. 7 and 9, the housing further includes a second gloss oil layer 60, and the second gloss oil layer 60 is disposed on the surface of the offset color layer (the transparent color layer 50) near the substrate, and the schematic structural diagram refers to fig. 10 and 11 (in the process, before the offset color layer is offset, a gloss oil layer is usually needed to be printed onto the screen to improve the adhesion of the offset color layer), so as to improve the adhesion of the offset color layer.
Wherein the thickness of the second gloss oil layer 60 is 4-8 microns, such as 4 microns, 5 microns, 6 microns, 7 microns or 8 microns. Therefore, the second gloss oil layer with the thickness has better adhesive force and is not easy to crack when being bent under high pressure and heat; if the thickness is less than 4 microns; if the thickness is smaller than 4 microns, the adhesive force is relatively poor, and the manufacturing process difficulty is high; if the thickness is greater than 8 μm, the second gloss oil layer 60 is easily broken when it is thermally bent.
Further, referring to fig. 12 and 13, the housing may further include: an ink cover primer layer 70 is provided on a surface of the second plating film layer 32 remote from the substrate 10 (see fig. 12), or on a surface of the offset color layer (i.e., the transparent color layer 40) remote from the substrate 10 (see fig. 13). Therefore, the light leakage of the shell can be avoided, and the external light effect of the shell is affected.
According to the embodiment of the application, the preparation process and the process parameters of the first texture layer, the first coating layer, the second texture layer, the second coating layer, the transparent color layer, the ink cover bottom layer and other structures are not particularly required, and a person skilled in the art can flexibly design the structure according to actual requirements, so long as a shell structure with good performance can be prepared. Such as: the first texture layer and the second texture layer can be prepared by a UV transfer printing technology, the first coating layer and the second coating layer can be prepared by an electroplating technology, the transparent color layer can be prepared by spraying or offset printing, and the ink cover bottom layer can be prepared by printing or coating and other methods.
Furthermore, the specific structure of the shell is not particularly required, and a person skilled in the art can flexibly select the specific structure according to practical situations, for example, the specific structure of the shell can be a 2D structure, a 2.5D structure or a 3D structure, and if the specific structure of the shell is the 2.5D structure or the 3D structure, the person skilled in the art can change the 2D structure plate into the 2.5D structure plate or the 3D structure plate by adopting high-pressure hot bending after forming each layer of structure, so as to obtain the shell with the 2.5D structure or the 3D structure.
Further, the shell further comprises a hardening layer positioned on the surface of the substrate far away from the first texture layer, so that scratch resistance of the appearance of the shell is improved.
