Description

Technical Field

[0001] This disclosure relates to the field of polymer materials technology, and in particular to a material with a glass-like texture, a preparation method thereof, and an electronic device. Background Technology

[0002] High-end laptops often use glass in the palm rest area to maintain a premium design and a smooth feel, giving the product a fresh look and enhancing the user experience. However, glass products are expensive, requiring manufacturers to further reduce costs to improve their products' market competitiveness.

[0003] Currently, the traditional way to reduce product costs is to replace glass products by printing directly onto PC or PET materials. This will seriously reduce the appearance quality. At the same time, because ordinary PC materials have low surface hardness, after prolonged use by users, they will have a series of quality problems such as surface wear and discoloration, fingerprint resistance, surface dirt, and difficulty in cleaning. Furthermore, the printing quality of PC and PET materials will reduce the appearance of the product, greatly reducing the product's competitiveness and the consumer's user experience.

A printing layer is applied to the second surface of the substrate layer to achieve the material's color gloss. The interaction between the printing layer and the texture layer further enhances the glass-like texture appearance. Therefore, the glass-like material prepared by this application has glass-like hardness, texture, and desired color appearance, meeting the user's product requirements. 2) This application's glass-like material, by forming an AF layer on the texture layer, allows the material to remain clean for a long time, maintaining the product's appearance. 3) This application, by setting a hardening layer on the substrate layer, gives the material glass-like hardness, and because the substrate layer is made of plastic, it greatly reduces production costs. 4) In the process of forming the texture layer of this application, two textures are superimposed to form a cross-arranged texture.

[0045] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0046] In a first aspect, the present disclosure provides a method for preparing a material with a glass-like texture, which can be implemented by choosing one of the following two preparation methods.

[0047] The first preparation method, combined with Figure 1 and Figure 3 As shown, a method for preparing a material with a glass-like texture includes the following steps:

[0048] A base layer 2 is provided, the base layer 2 including a first surface and a second surface opposite to each other, and the first surface of the base layer 2 is strengthened to form a hardened layer 3;

[0049] UV transfer is performed on the hardened layer 3 to form a textured layer 4 on the hardened layer 3;

[0050] The second surface of the base layer 2 is printed with printing ink to form a printed layer 1 with a set color.

[0051] The preparation method of this application strengthens the first surface of the substrate layer 2, giving the prepared glass-like material (hereinafter referred to as "the material") a glass-like hardness. Then, a textured layer 4 is formed on the hardened layer 3 via UV transfer printing. This gives the prepared material a texture and smooth touch similar to real glass, solving the problem of the obstructed touch caused by directly printing on PC or PET materials to replace glass products in the past. For example, printing can be done in multiple stages, with baking after each printing. This printing process creates a multi-layered color printing layer to meet the user's requirements for product color and gloss.

[0052] The second preparation method, combined with Figure 2 and Figure 4 As shown, a method for preparing a material with a glass-like texture includes the following steps:

[0053] A base layer 2 is provided, the base layer 2 including a first surface and a second surface opposite to each other, and the first surface of the base layer 2 is strengthened to form a hardened layer 3.

[0054] UV transfer is performed on the hardened layer 3 to form a textured layer 4 with a logo cutout area 41 on the hardened layer 3;

[0055] The logo is printed in the first area of ​​the second surface using printing ink to form a logo printing layer 11 in the first area, and a main printing layer 12 is formed by printing ink in the area outside the first area. The logo printing layer 11 and the main printing layer 12 constitute printing layer 1, wherein the logo printing layer 11 is positioned corresponding to the logo cutout area 41.

[0056] The preparation method of this application involves strengthening the first surface of the substrate layer 2 to give the prepared material a glass-like hardness. Then, a textured layer 4 with a logo cutout area 41 is formed on the hardened layer 3 using UV transfer printing. Finally, a logo printing layer 11 and a main printing layer 12 are printed on the second surface of the substrate layer using printing ink. This gives the material glass-like hardness, texture, and a smooth, glass-like feel, solving the problem of tactile discomfort caused by directly printing on PC or PET materials to replace glass products. By setting the logo printing layer 11 and the logo cutout area 41, the logo is displayed on the textured layer, highlighting the logo on the material. For example, printing can be done multiple times to create a multi-layered printing structure (including the main printing layer and the logo printing layer) to meet the user's color and gloss requirements for the product.

[0057] Both of the above-described preparation methods can be used to prepare the glass-like material required for this application. The first method can be used when the material does not require a logo. The final glass-like material will have a similar texture to glass while also possessing a precisely defined color. For example, when this material is applied to the outer frame of a laptop screen, it can achieve a perfect black finish while maintaining a glass-like texture.

[0058] When a logo is required on a material with a glass-like texture, a second method can be used. In this method, since the texture layer has a logo cutout area 41, which does not have a texture, the hardened layer can be exposed in the logo cutout area. Since the hardened layer and the base layer have good transparency, when a logo printing layer 11 is provided on the second surface of the base layer, the logo printing layer 11 can be seen through the base layer and the hardened layer, and finally the logo is displayed in the texture layer.

[0059] In this embodiment, the substrate layer 2 is made of one or more of PU (polyurethane), PET (polyethylene terephthalate), PC (polycarbonate), and PMMA (polymethyl methacrylate). Therefore, preferably, the substrate layer 2 can be a PU layer, a PET layer, a PC layer, or a PMMA layer.

[0060] Since the hardness of the base layer 2 itself does not reach that of glass, a hardening layer 3 is formed on the first surface of the base layer 2. This increases the overall hardness of the base layer with the hardening layer, giving it a hardness similar to glass. For example, the pencil hardness value of the hardening layer is increased to F to 4H. Examples of pencil hardness values ​​are F, H, 2H, 3H, and 4H. A pencil hardness value of 2H is preferred.

[0061] For example, a hardened layer 3 is formed on the first surface of the substrate 2 by plating, spraying, or coating. Taking a substrate made of PC material as an example, the surface strengthening treatment is illustrated below, specifically including the following steps:

[0062] Step 1-1): A single-component ultraviolet light hardening liquid forms a hardened layer on the first surface of the PC material by spray coating. The spray coating equipment nozzles move from left to right along the same horizontal line.

[0063] Steps 1-2): After the coating is completed, keep the plate vertical for about 2 minutes to allow the surface to evaporate and level freely, and then put it into a 60-70℃ drying tunnel and keep it vertical for 5 minutes.

[0064] Steps 1-3): After heating, the film enters the UV curing lamp area for conventional curing; the curing time can be adjusted according to the lamp energy, which is beneficial to improving the hardness of the film layer; for example, in this embodiment, the UV curing lamp energy is 2000W and the lamp tube length is 30cm during the test experiment.

[0065] Steps 1-4): After curing, cool the material to room temperature.

[0066] After the surface of the PC material is strengthened, a hardened layer is formed on the surface, with a thickness of 5-8 μm and a hardness value of 2H. The PC material is then subjected to QUV (Quick UV) resistance testing, and the QUV resistance is >200 hours.

[0067] In this embodiment, the surface strengthening treatment of the PC material is achieved through a curtain coating process. Of course, other methods can also be used, such as plating or spraying. However, curtain coating (such as...) Figure 5 (b) shows a comparison with traditional surface spraying (such as...) Figure 5 (a) will achieve a more uniform coverage and improve the uniformity of the PC material surface.

[0068] In this embodiment, in the first preparation method, the second surface of the base layer 2 is printed with a printing coating to form a printed layer 1 with a set color. For example... Figure 3 As shown.

[0069] The printing coating is composed of a mixture of resin and color masterbatch, or it can be made from ink resin. The printing coating achieves a glossy appearance similar to a glass-like material surface. In the actual printing process, multiple printings can be performed to create color layering. For example, after the first printing (e.g., black), it is baked at 60-70°C; then a second printing is performed to create a stronger color (e.g., a stronger black), and it is baked again at 60-70°C, thus giving the printed layer 1 an extreme set color (e.g., extreme black). This printed layer 1 completely covers the second surface of the base layer 2.

[0070] In the second preparation method, a logo is printed in the first area of ​​the second surface using printing paint to form a logo printing layer 11. In the area outside the first area (i.e., the remaining area on the second surface excluding the first area), printing paint is used to form a main printing layer 12. The logo printing layer 11 and the main printing layer 12 constitute printing layer 1, wherein the logo printing layer 11 is positioned corresponding to the logo cutout area 41.

[0071] like Figure 4 As shown, after the first printing (e.g., black) is performed on all areas except the first area on the second surface of the base layer, it is baked at 60-70°C, followed by a second printing to form an enhanced color, and then baked again at 60-70°C to form the main printing layer 12. Finally, the logo is printed a third time on the first area of ​​the second surface, and then baked at 60-70°C to form the logo printing layer 11. Figure 2 It can be seen that the surface of the logo printing layer 11 and the surface of the main printing layer 12 are on the same plane. Of course, the logo can also be printed on the first area first, and then the areas outside the first area can be printed.

[0072] The logo is printed using printing ink in the first area of ​​the second surface to form a logo printing layer 11. The area outside the first area is also printed using printing ink to form a main printing layer 12. The surfaces of the logo printing layer 11 and the main printing layer 12 are on the same plane. The logo printing layer 11 and the main printing layer 12 constitute printing layer 1, with the logo printing layer 11 corresponding to the position of the logo cutout area 41. During printing, multiple printings can be performed to create color overlays, and each printing is followed by baking at 60-70°C. To differentiate the colors of the logo printing layer 11 and the main printing layer 12 and highlight the logo, the colors of the logo printing layer 11 and the main printing layer 12 can be set to strong contrast colors to emphasize the logo on the logo printing layer. For example, the logo printing layer 11 can be a deep red, and the main printing layer 12 can be a deep black. Alternatively, the logo printing layer 11 and the main printing layer 12 can be set to the same color but different shades to highlight the logo. For example, the logo printing layer can be set to high gloss black, and the main printing layer 12 can be set to extreme black. This will also allow the logo printing layer to be displayed in the logo cutout area on the texture layer.

[0073] For example, refer to again Figure 3 and Figure 4After the UV transfer process completes the formation of the texture layer, the material needs to be cut before printing. Cutting, also known as sizing, involves cutting the material to the required size and shape. After cutting, multiple printing processes are then performed.

[0074] In one embodiment, such as Figure 7 As shown, forming a texture layer 4 on the hardened layer 3 by UV transfer includes:

[0075] A glass transfer mold is provided, on which a predetermined glass texture is pre-processed; wherein the glass texture includes a first texture and a second texture, the second texture is superimposed on the first texture and the two are arranged in an intersecting pattern;

[0076] UV adhesive is screen-printed onto a transfer mold;

[0077] Place the hardened layer side of the base layer 2 onto the transfer mold, and then use a rubber roller to press the base layer 2 firmly onto the transfer mold;

[0078] The base layer and transfer mold are cured with UV light to achieve texture transfer; after demolding, a texture layer 4 is formed on the surface of the hardened layer 3, thereby realizing the transfer of glass texture on the base layer.

[0079] Or, it could also be, such as Figure 7 As shown, UV transfer is performed on the hardened layer 3 to form a textured layer 4 with a logo cutout area 41, which includes:

[0080] A glass transfer mold is provided. A logo area is reserved on the surface of the transfer mold, and a predetermined glass texture is processed in the area outside the logo area. The glass texture includes a first texture and a second texture, with the second texture superimposed on the first texture and the two textures arranged in an intersecting pattern.

[0081] UV adhesive is screen-printed onto a transfer mold;

[0082] Place the hardened layer on the base layer onto the transfer mold, and then use a rubber roller to press the base layer firmly onto the transfer mold;

[0083] The base layer 2 and the transfer mold are cured with UV light; the mold is then removed, thereby forming a texture layer 4 with a logo cutout area 41 on the surface of the hardened layer 3, thus realizing the transfer of the glass texture on the base layer.

[0084] Both of the above methods use UV transfer printing to create superimposed textures to replace the AG (anti-glare) treatment process of real glass in order to achieve a similar surface texture. Therefore, the glass-like texture material of this application has a high-end texture similar to glass, which meets the high-end needs of products.

[0085] In both of the above-mentioned methods for preparing textured layers, the transfer molds are made of glass, and a predetermined glass texture is pre-processed on the surface of the transfer mold, as shown in Figure 7. This glass texture includes a first texture ( Figure 7 The texture shown) and the second texture ( Figure 7 The textures shown are V-shaped, and are superimposed to form a cross-patterned texture. After the texture transfer to the base layer is completed, a sandy texture layer is formed on the surface of the hardened layer, thus giving the material a unique sandy texture. Furthermore, by superimposing and cross-patterning the two textures, the texture layer and the printed layer work together to simulate the anti-glare texture effect of real glass, giving it a surface texture similar to real glass. This is because, during UV transfer printing, the two textures are pre-processed on the transfer mold in a superimposed and cross-patterned manner. This results in a rough, uneven surface when the texture layer is formed on the surface of the hardened layer. When light is projected onto the texture layer, its uneven surface reduces reflectivity, creating diffuse reflection. Furthermore, the presence of the printed layer absorbs light, further reducing the material's reflectivity. Therefore, through the combined effect of the texture layer and the printed layer, the material achieves an anti-glare effect similar to real glass.

[0086] Furthermore, the predetermined glass texture can be processed on the transfer mold using existing known methods such as etching and laser, which will not be elaborated here.

[0087] Traditional UV transfer textures, such as Figure 6 As shown, this traditional texture is generally circular in shape. Compared with the traditional UV transfer texture, this embodiment has made an innovation by simulating the gritty feel required by users by superimposing and arranging the texture in a cross pattern, thereby improving user satisfaction with the product.

[0088] Furthermore, this application specifies the following texture data control standards for glass-like materials: Ra (arithmetic mean deviation of the profile) is between 0.565 and 0.582, Rz (maximum peak-to-valley height of roughness) is between 4.411 and 4.513, and Rpc (roughness profile coefficient) is between 105.840 and 110.530. Of course, users can adjust and control the texture data in production according to their actual needs.

[0089] In one embodiment of this disclosure, reference is made again. Figure 3 and Figure 4The preparation method disclosed herein further includes forming an AF layer 5 on the surface of the textured layer 4 by physical vapor deposition; wherein the water droplet angle of the AF layer is >120°. The target material selected for physical vapor deposition is a silicon-fluorine based target material; and an inert protective gas such as He or Ar is used. Preferably, the thickness of the AF layer is 0.015–0.02 μm.

[0090] An AF layer (fingerprint resistant layer) is formed on the surface of texture layer 4 by physical vapor deposition (PVD). The AF layer must meet the following requirements: water droplet angle >120°, and abrasion resistance at the water droplet angle decreases by 9.11% to 14.66%. When the water droplet angle of the AF layer is >120° and the abrasion resistance at the water droplet angle decreases by 9.11% to 14.66%, the AF layer has good stain resistance and scratch resistance, extending the product's service life and maintaining the product's aesthetic appearance for a long time.

[0091] The glass-like material prepared according to the above method was subjected to performance tests. The results showed that the cross-cut adhesion score was >5B, the surface pencil hardness was 3H, and the alcohol abrasion resistance test was >500 cycles (with a load of 500g). The coating remained colorless for 120 hours at 60℃ and 30% humidity, and for 96 hours at -40℃. This indicates that the glass-like material prepared using the method described in this application has good scratch resistance and stain resistance, and the material possesses a glass-like texture and hardness while maintaining its aesthetic appearance for a long time, thus enhancing product competitiveness.

[0092] Secondly, this disclosure first provides a material with a glass-like texture. This glass-like texture material is prepared by the preparation method of any one embodiment of the first aspect. Therefore, the glass-like texture material prepared by the first and second preparation methods described above has two different structures.

[0093] The first structure, such as Figure 1 As shown, a glass-like material comprises a printed layer 1, a base layer 2, a hardened layer 3, and a textured layer 4, stacked sequentially from the inside out. This application provides a glass-like material by providing a hardened layer 3 on the base layer 2 to give the material glass-like hardness, and by providing a textured layer 4 to give the material both glass-like hardness and a glass-like texture. Furthermore, the printed layer achieves the material's color gloss, ultimately giving the glass-like material glass-like hardness, texture, and desired color appearance, thus meeting the user's product requirements.

[0094] A texture layer 4 is formed on the surface of the hardened layer 2 using UV transfer printing. This allows the final glass-like material to achieve the desired color (such as a perfect black) while possessing glass-like hardness and texture. This significantly enhances the material's premium feel and quality, bringing a new aesthetic to the product and improving the user experience.

[0095] Refer to again Figure 1 In this embodiment, a glass-like material further includes an AF layer 5 stacked on the texture layer 4. Forming an AF layer (fingerprint resistant layer) on the texture layer 4 further enhances the stain resistance and scratch resistance of the glass-like material surface. This allows the glass-like material to possess a similar texture to glass while also maintaining long-term stain and scratch resistance, effectively preserving the high-end feel and quality of electronic products using this material. For example, the thickness of the AF layer is 0.015–0.02 μm.

[0096] The second structure, such as Figure 2 As shown, a glass-like material includes a printing layer 1, a base layer 2, a hardening layer 3, and a texture layer 4 stacked sequentially from the inside out. The printing layer 1 includes a main printing layer 12 and a logo printing layer 11, with the surfaces of the logo printing layer 11 and the main printing layer 12 on the same plane. The logo printing layer 11 is disposed in a first area on the surface of the base layer, and the main printing layer 12 is disposed in an area outside the first area. A logo cutout area 41 is provided in the texture layer 4, which is located opposite to the logo printing layer 11, so that the logo of the logo printing layer is displayed through the logo cutout area.

[0097] Refer to again Figure 2 In this embodiment, a glass-like material further includes an AF layer 5 stacked on the texture layer 4. Forming an AF layer (fingerprint resistant layer) on the texture layer 4 can further increase the stain resistance and scratch resistance of the glass-like material surface, so that the glass-like material has a similar glass texture while also having long-term stain resistance and scratch resistance, effectively maintaining the high-end texture and quality of electronic products using this material.

[0098] Thirdly, this disclosure provides an electronic device including the glass-like textured material described in the second aspect. This glass-like textured material can be used in the palm rest (C component) of a laptop, the screen frame (B component) of a laptop, and also in the casing of a tablet, camera, etc. Electronic devices with this glass-like textured material meet high-end product requirements, achieving a glass-like texture while offering exquisite color options. It reduces production costs, and because the material surface has an AF layer, the surface remains clean even after prolonged use, maintaining the product's appearance for an extended period.

[0099] For example, when the glass-like material of this application is applied to the palm rest of a laptop computer, the AF layer is facing upwards towards the user, achieving a glass-like texture for the material while meeting the user's aesthetic requirements.
