[0032] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] See also Figure 1 The embodiment of the present application provides a curved glass 100, which includes a micro-nano textured surface 10 provided on its outer surface, an inner surface 101, two side surfaces and two end surfaces, wherein the micro-nano textured surface 10 is a rough surface, the inner surface 101 is a smooth surface, the side surface of the curved glass 100 is a smooth surface, and the end surface of the curved glass 100 is a smooth surface. The inner surface 101 can be a plane, or a curved surface, or part of the inner surface 101 can be a plane and the other part can be a curved surface, which is not limited here.

[0034] The micro-nano textured surface 10 and the inner surface 101 are arranged opposite to each other along the thickness direction of the curved glass 100; the two side surfaces are a first side surface 102 and a second side surface 103, the first side surface 102 and the second side surface 103 are arranged opposite to each other along the length direction of the curved glass 100, the first side surface 102 is connected between the micro-nano textured surface 10 and the inner surface 101, and the first side surface 102 is connected to the same side of the micro-nano textured surface 10 and the inner surface 101, that is, Figure 1The second side surface 103 is connected between the micro-nano texture surface 10 and the inner surface 101, and the second side surface 103 is connected to the same side of the micro-nano texture surface 10 and the inner surface 101, that is Figure 1 The two end surfaces are a first end surface 104 and a second end surface 105, which are arranged opposite to each other along the width direction of the curved glass 100, the first end surface 104 is connected between the micro-nano texture surface 10 and the inner surface 101, and the first side surface 102 is connected to the same side of the micro-nano texture surface 10 and the inner surface 101, that is, Figure 1 On the left side, the second side surface 103 is connected between the micro-nano texture surface 10 and the inner surface 101, and the second side surface 103 is connected to the same side of the micro-nano texture surface 10 and the inner surface 101, that is, Figure 1 The micro-nano textured surface 10 , the inner surface 101 , the first side surface 102 , the second side surface 103 , the first end surface 104 , and the second end surface 105 together form the surface of the curved glass 100 .

[0035] See also Figure 1 and Figure 2 The micro-nano texture surface 10 includes a first micro-nano texture surface 11 and a second micro-nano texture surface 13, the first micro-nano texture surface 11 and the second micro-nano texture surface 13 are smoothly connected, the first micro-nano texture surface 11 is provided with a plurality of first texture units 111, the plurality of first texture units 111 are arranged at intervals along a preset direction on the first micro-nano texture surface 11, the second micro-nano texture surface 13 is provided with a plurality of second texture units 131, the plurality of second texture units 131 are arranged at intervals along a preset direction on the second micro-nano texture surface 13, and the relative average deviation of the size of the plurality of first texture units 111 and the size of the plurality of second texture units 131 is ≤10%. When light is irradiated to the first micro-nano texture surface 11 and the second micro-nano texture surface 13, the first micro-nano texture surface 11 and the second micro-nano texture surface 13 can reflect the light, the relative average deviation of the size of the plurality of first texture units 111 and the size of the plurality of second texture units 131 is small, and the refraction of light at different angles produces a delicate light and shadow change effect, and the texture on the curved glass 100 is rich in decorativeness.

[0036] The above-mentioned preset direction refers to the direction parallel to the micro-nano texture surface 10. In the present embodiment, the preset direction is parallel to the long side of the micro-nano texture surface 10, the first texture unit 111 is parallel to the first end surface 104 and the second end surface 105, and the second texture unit 131 is parallel to the first end surface 104 and the second end surface 105. In other embodiments, the preset direction may be parallel to the short side of the micro-nano texture surface 10, the first texture unit 111 is parallel to the first side surface 102 and the second side surface 103, and the second texture unit 131 is parallel to the first side surface 102 and the second side surface 103. In other embodiments, the preset direction may be parallel to the diagonal line of the micro-nano texture surface 10, and the preset direction may also be at other angles to the long side or short side of the micro-nano texture surface 10, which is not limited here.

[0037] Furthermore, the relative average deviation of the sizes of the plurality of first texture units 111 is ≤10%, or the size deviation of any two first texture units 111 is ≤10%. The relative average deviation of the sizes of the plurality of second texture units 131 is ≤10%, or the size deviation of any two second texture units 131 is ≤10%, or the size deviation of any second texture unit 131 and any first texture unit 111 is ≤10%.

[0038] The first micro-nano texture surface 11 is provided with a plurality of first texture units 111 arranged approximately evenly, and the second micro-nano texture surface 13 is provided with a plurality of second texture units 131 arranged approximately evenly. When light is irradiated to the first micro-nano texture surface 11 and the second micro-nano texture surface 13, the plurality of first texture units 111 on the first micro-nano texture surface 11 can reflect the light, and the plurality of second texture units 131 on the second micro-nano texture surface 13 can reflect the light. On the one hand, since the relative average deviation and size deviation of the sizes of the plurality of first texture units 111 are small, and the relative average deviation and size deviation of the sizes of the plurality of second texture units 131 are small, and the size deviation of any second texture unit 131 and any first texture unit 111 is small, the texture units of the micro-nano texture surface 10 refract light at different angles to produce a delicate light and shadow change effect, and the texture is rich in decorativeness; on the other hand, the micro-nano texture surface 10 has a consistent feel at each position without a convex point feeling, thereby improving the feel of the curved glass 100. In addition, the first texture unit 111 and the second texture unit 131 in the present application are nano-scale textures, so that the micro-nano texture surface 10 has a soft touch and a good user experience.

[0039] In some embodiments, the first micro-nano texture surface 11 is a curved surface, and the second micro-nano texture surface 13 can be a plane or a micro-curved surface. The micro-curved surface refers to a surface with a slight curvature but a small curvature, which appears to be relatively flat to the naked eye. Exemplarily, the micro-nano texture surface 10 includes a second micro-nano texture surface 13 and two first micro-nano texture surfaces 11, and the second micro-nano texture surface 13 is connected between the two first micro-nano texture surfaces 11. The opposite ends of the curved glass 100 have obvious curvatures, so that the second micro-nano texture surface 13 is more prominent relative to the two first micro-nano texture surfaces 11, and thus the curved glass 100 has a more eye-catching appearance effect, and the curved glass 100 is more three-dimensional. The first texture unit 111 is arranged on the first micro-nano texture surface 11, and the second texture unit 131 is arranged on the two second micro-nano texture surfaces 13, which can further increase the visual effect.

[0040] See also Figure 2 and Figure 3 The first texture unit 111 is a convex stripe structure, the second texture unit 131 is a convex stripe structure, the plurality of first texture units 111 are arranged at intervals, and a first groove 1113 is formed between each adjacent two first texture units 111; the plurality of second texture units 131 are arranged at intervals, and a second groove 1313 is formed between each adjacent two second texture units 131, and the first texture unit 111 close to the second micro-nano texture surface 13 among the plurality of first texture units 111 and the second texture unit 131 close to the first micro-nano texture surface 11 among the plurality of second texture units 131 are adjacent to and spaced apart from each other.

[0041] The above-mentioned first texture unit 111 and second texture unit 131 are nano-scale textures, which means that the first texture unit 111 and the second texture unit 131 are measured in nanometers, that is, the spacing value D between any two adjacent first texture units 111, the spacing value D between any two adjacent second texture units 131, and the spacing value D between adjacent first texture units 111 and first texture units 111 are all measured in nanometers; that is, the width value W of any first texture unit 111 and the width value W of any second texture unit 131 are both measured in nanometers; that is, the height value H of any first texture unit 111 and the height value H of any second texture unit 131 are both measured in nanometers.

[0042] The spacing value D between the two adjacent first texture units 111 refers to the width value of the first groove 1113 between the two adjacent first texture units 111; the spacing value D between the two adjacent second texture units 131 refers to the width value of the second groove 1313 between the two adjacent second texture units 131. The height value H of the first texture unit 111 refers to the thickness value of the first texture unit 111 along the direction perpendicular to the surface of the curved glass 100; the height value H of the second texture unit 131 refers to the thickness value of the second texture unit 131 along the direction perpendicular to the surface of the curved glass 100.

[0043] A plurality of first texture units 111 and a plurality of first grooves 1113 are alternately distributed on the first micro-nano texture surface 11, and a plurality of second texture units 131 and a plurality of second grooves 1313 are alternately distributed on the second micro-nano texture surface 13, so that the texture units on the micro-nano texture surface 10 are more evenly distributed, and the light and shadow changing effect produced by the curved glass 100 on light is more delicate and more decorative.

[0044] For ease of description, the specific structure of the curved glass 100 will be described below by taking the example that the number of the first texture units 111 of the first micro-nano texture surface 11 is n and the number of the second texture units 131 of the second micro-nano texture surface 13 is m.

In an embodiment in which the first texture unit 111 is a regular pyramid structure, the cross section of the first texture unit 111 along its width direction is a triangle. In an embodiment in which the first texture unit 111 is a regular prism structure, the cross section of the first texture unit 111 along its width direction is a trapezoid. In an embodiment in which the first texture unit 111 is a regular hemispherical structure, the cross section of the first texture unit 111 along its width direction is a semicircle.

[0063] The above-mentioned “quasi-regular structure” can be explained as follows. For example, a quasi-regular structure of a cuboid refers to a structure that is similar to a cuboid, but is not a standard cuboid structure, for example, one or more edges of the cuboid structure have a curvature, or the angle is not a right angle, or one or more surfaces of the cuboid structure are curved; for example, a quasi-regular structure of a prism refers to a structure that is similar to a prism, but is not a standard prism structure, for example, one or more edges of the prism-like structure have a curvature, or one angle is missing, or the edges have a curvature, etc.; a quasi-regular structure of a pyramid refers to a structure that is similar to a pyramid, but is not a standard pyramid structure, for example, one or more edges of the pyramid-like structure have a curvature, or one angle is missing, or the edges have a curvature, etc.; a quasi-regular structure of a pyramid refers to a structure that is similar to a pyramid, but is not a standard pyramid structure, for example, one or more edges of the pyramid-like structure have a curvature, or one angle is missing, or the edges have a curvature, etc. A hemispherical quasi-regular structure refers to a structure that is similar to a hemispherical structure, but is not a standard hemispherical structure. For example, the radii of the hemispherical quasi-structure are not completely equal, the hemispherical quasi-structure is a semi-ellipsoidal structure, etc. Other quasi-regular structures can be explained in the same or similar manner.

[0064] The cross section of the second texture unit 131 is a regular geometric shape. Specifically, the second texture unit 131 can be a regular rectangular parallelepiped structure, a prism structure, a pyramid structure, a prism structure, a hemispherical structure, etc., or the second texture unit 131 can be a quasi-regular structure. The second texture unit 131 has a similar structure to the first texture unit 111, and will not be described in detail here.

[0065] In the curved glass 100, the shapes of the first texture unit 111 and the second texture unit 131 are different, and the patterns of the first micro-nano texture surface 11 and the second micro-nano texture surface 13 are also different, which makes the curved glass 100 more variable and can produce different light and shadow changing effects on light to meet the different needs of different consumers.

[0066] For example, see Figure 2 and Figure 3 , the first texture unit 111 of the first micro-nano texture surface 11 is a regular rectangular parallelepiped structure, and the cross section of the first texture unit 111 along its width direction is a rectangle. The second texture unit 131 of the second micro-nano texture surface 13 is a regular rectangular parallelepiped structure, and the cross section of the second texture unit 131 along its width direction is a rectangle. In this example, the spacing value between two adjacent second texture units 131 refers to the spacing value of two adjacent second texture units 131 close to the second groove 1313.

[0067] For example, see Figure 4 , the first texture unit 111 of the first micro-nano texture surface 11 is a regular hemispherical structure, and the cross section of the first texture unit 111 along its width direction is semicircular. The second texture unit 131 of the second micro-nano texture surface 13 is a regular hemispherical structure, and the cross section of the second texture unit 131 along its width direction is semicircular. In this example, the spacing value between two adjacent second texture units 131 refers to the spacing value of two adjacent second texture units 131 close to the second groove 1313.

[0068] See also Figure 1 and Figure 5 The curved glass 100 of the embodiment of the present application is obtained by processing a glass body 120. The glass body 120 is made of a glass substrate. The preparation method of the glass body 120 can be but is not limited to melting molding, casting molding, stretching molding or extrusion molding. The glass body 120 forms a micro-nano texture surface 10 on the first surface 122 by chemical etching, thereby preparing the curved glass 100. The curved glass 100 provided in the embodiment of the present application can be applied to electronic devices such as mobile phones, tablet computers, laptops, desktop computers, smart bracelets, smart watches, e-readers, game consoles, etc. The curved glass 100 provided in the embodiment of the present application can be a battery cover, shell, middle frame, decorative parts, etc. of electronic devices.

[0069] The embodiment of the present application provides a method for preparing curved glass. The method for preparing curved glass of the present application can be used to prepare the curved glass described in the embodiment of the present application. The method for preparing curved glass includes:

[0070] The first step is to obtain a glass body.

[0071] The glass body is made of a glass substrate, and the glass substrate is prepared to form the glass body by melting molding, casting molding, stretching molding or extrusion molding.

[0072] The second step is to design and make the target mold.

[0073] According to the size of the glass body, the film used to make the target mold is cut into the required size, and then made into a target mold with a target texture unit. The film used to make the target mold is cut into a suitable size. For example, the film used to make the target mold is cut into a size of 225mm*225mm. The shape of the target texture unit is a regular geometric shape. Optionally, the target texture unit can be a regular rectangular parallelepiped structure, a prism structure, a pyramid structure, a prism structure, a hemispherical structure, or the above-mentioned regular structures.

[0074] The third step is spraying glue.

[0075] The outer surface of the glass body provided in the first step is sprayed with glue. Specifically, a glue dispenser with a rotating spray head is used to spray a layer of thermosetting glue on the outer surface of the glass body.

[0076] The fourth step is high pressure forming.

[0077] A target mold having a target texture unit is covered on the surface of the thermosetting adhesive of the glass body, so that the thermosetting adhesive of the glass body is squeezed on a side facing away from the glass body to form a texture unit to be processed that is opposite to the target texture unit of the target mold. "The target texture unit of the target mold is opposite to the texture unit to be processed of the glass body" means that the target texture unit can be inserted into the adhesive layer of the glass body to form a texture groove, and at least part of the adhesive layer of the glass body is received in the receiving groove between two adjacent target texture units to form a texture unit to be processed.

[0078] Specifically, first, the upper mold and the lower mold of the high-pressure molding machine are heated to the curing temperature of the thermosetting adhesive in advance. Then, the glass body is placed on the lower mold of the high-pressure molding machine together with the positioning fixture, and the target mold with the target texture unit is positioned on the surface of the glass body with the thermosetting adhesive through the positioning fixture. A membrane is covered on the side of the target mold away from the glass body, so that the target mold and the glass body fit more closely. Then, the high-pressure molding machine is started, and the pusher of the high-pressure molding machine and the heating plate are positioned above the lower mold for baking. This process helps the target mold to fit the glass body closely during the high-pressure molding process, so that the target texture unit of the glass body is consistent in regularity, and at the same time, the equipment is ensured to have good sealing. After the baking is completed, the heating plate is reset, the upper mold and the lower mold of the high-pressure molding machine are closed, and the high-pressure molding machine is pressurized and vacuumed at the same time. When the cavity pressure of the high-pressure molding machine reaches the set value, the pressure is maintained, that is, high-pressure molding is performed. After the pressure is maintained, the vacuuming part of the high-pressure molding machine is opened to the atmosphere for pressure relief. When the pressure is equal to the atmospheric pressure, the mold is opened and the glass body is taken out.

[0079] Step five: apply glue.

[0080] Specifically, the glue covering the groove surface of the texture groove of the glass body is removed to expose the groove surface of the texture groove of the glass body, and the groove surface of the texture groove is used to contact the etching solution; the glue at the position of the texture unit to be processed of the glass body is retained, and the glue retained here plays an isolation role, which is used to isolate the glass body and the etching solution, thereby protecting the glass body; and then an ultrasonic cleaning machine is used to remove the glue debris on the surface of the glass body.

[0081] Step 6: Etching.

[0082] Specifically, the glass body obtained in the fifth step is immersed in an etching solution of a certain concentration. After a certain period of time, the product is repeatedly rinsed with clean water to ensure that no etching solution remains on the surface of the glass body.

[0083] Step seven, debonding.

[0084] The glue at the position of the texture groove of the glass body is removed. Specifically, the corrosion-resistant glue tank filled with alkaline degumming liquid is placed in an ultrasonic cleaning machine, and after heating to a certain temperature, the glass body obtained in the sixth step is placed in the ultrasonic cleaning machine for several minutes to ensure that the product has good cleanliness, and then the product is dried. All process flows are completed, and the embodiment of the present application provides a curved glass preparation.

Then, use the polishing process to grind away the scratch defects on the outer surface of the curved glass.

[0089] The curved glass obtained in the above-mentioned Example 1, Example 2 and Comparative Example 1 was subjected to appearance test. The appearance test includes a curved surface texture accuracy test, a texture dirt test and a texture appearance test, wherein the texture dirt test is characterized by an optical microscope with a three-dimensional testing function, and is used to test whether the low and high parts of the texture are smooth and flat, whether there are abnormal impurities, and whether the appearance is transparent throughout and whether the light and shadow effects are consistent; the texture appearance test visually inspects micro-nano texture products with different sizes and shapes to detect whether they have light and shadow effects, and then determines the texture decoration appearance effect.

[0091] Project / Sample Example 1 Example 2 Comparative Example 1 Surface texture error test ≤10％ ≤10％ ≤25％ Texture Dirt Test none none high Texture appearance test excellent excellent Difference
