The scope of the application is defined by the appended claims.

The basic concepts involved in the embodiments of the present application will be briefly described below.

The term "glass matrix" is a silicate-based nonmetallic material having a large number of-Si-O-Si-network structures within, but such networks cannot be extended indefinitely. The "s i l ano l group" is a silanol end, i.e. on the physical surface of the glass, the Si-O-Si-network is terminated with silanol end groups (s i l ano l) of Si-O-H.

Referring to fig. 1, fig. 1 is a cross-sectional view of a decoration 100 according to a first embodiment of the present application. The trim piece 100 includes a first glass substrate 10 and a second glass substrate 30. The second glass substrate 30 is bonded to the first glass substrate 10. The first glass substrate 10 includes oppositely disposed first and second surfaces 11 and 12. The second glass substrate 30 includes oppositely disposed third and fourth surfaces 31, 32. The first surface 11 of the first glass substrate 10 is provided with a first texture 13 and the third surface 31 of the second glass substrate 30 is provided with a second texture 33. The second surface 12 of the first glass substrate 10 is configured as a flat surface. The fourth surface 32 of the second glass substrate 30 is in sealing connection with the first texturing 13, and a first interior space 201 between two adjacent first texturing 13 is formed between the first glass substrate 10 and the second glass substrate 30.

According to the decoration 100 provided by the application, on one hand, the second glass substrate 30 is attached to the first glass substrate 10, so that the first glass substrate 10 and the second glass substrate 30 are combined into a whole, and the overall structural strength of the decoration 100 is improved, and the shock resistance is good. On the other hand, the first surface 11 of the first glass substrate 10 is provided with a first texture 13, and the third surface 31 of the second glass substrate 30 is provided with a second texture 33; the fourth surface 32 of the second glass substrate 30 is in sealing connection with the first texture structures 13, and a first inner space 201 between two adjacent first texture structures 13 is formed between the first glass substrate 10 and the second glass substrate 30, so that the texture effect of the first texture structures 13 is ensured, the number of times of reflection and refraction of light rays is increased through the first texture structures 13 and the second texture structures 33 is realized, the light intensity inside the decorative pattern is further increased, the decorative element 100 presents a more dazzling and stereoscopic appearance decorative effect, and the use effect and the decorative effect of the decorative element 100 are improved.

The arrangement of the first glass substrate 10 and the second glass substrate 30 is only schematically described in fig. 1, and the positions, arrangement relationships, specific structures, and the like of the respective elements are not particularly limited. Fig. 1 is merely a schematic structure of a decoration 100 according to an embodiment of the present application, and does not constitute a specific limitation of the decoration 100. In other embodiments of the present application, trim piece 100 may include more or fewer components than shown in FIG. 1, or certain components may be combined, or different components, for example trim piece 100 may also include, but is not limited to, a coating, ink, sanding, etc.

For the sake of more clear description, the X-axis direction is defined as the width direction of the garnish 100. The width direction of the decoration 100 is a direction parallel to a preset direction along which the plurality of first protrusions 131 and the plurality of first groove portions 132 and the plurality of second protrusions 331 and the plurality of second groove portions 332 are each alternately arranged independently. The Y-axis direction is defined as the thickness direction of the garnish 100, i.e., the lamination direction of the first glass substrate 10 and the second glass substrate 30. Illustratively, the direction opposite to the arrow direction of the Y-axis direction is downward with the arrow direction of the Y-axis direction being upward.

In some embodiments, the second surface 12 of the first glass substrate 10 is configured as a planar surface to facilitate decoration of the first glass substrate 10 by film coating, spray coating, or the like. The fourth surface 32 of the second glass substrate 30 is also configured as a flat surface, so that the sealing connection between the fourth surface 32 of the second glass substrate 30 and the first texture structure 13 is better ensured, the connection strength between the first glass substrate 10 and the second glass substrate 30 is increased, and the problem that the texture effect of the first texture structure 13 is poor after the first texture structure 13 is filled with ink or other functional adhesive layers is avoided. The flatness of the fourth surface 32 of the second glass substrate 30 is 0.01 μm to 100 μm, and the roughness of the fourth surface 32 of the second glass substrate 30 is 0.01nm to 100nm. It will be appreciated that the smaller the flatness and roughness of the fourth surface 32 of the second glass substrate 30, the more advantageous the fit of the first glass substrate 10 to the second glass substrate 30. Specifically, in the present embodiment, the air can be better exhausted while ensuring the flatness and roughness of the fourth surface 32 of the second glass substrate 30, so as to achieve that the first glass substrate 10 and the second glass substrate 30 are pressed together by the atmospheric pressure until the space between the first glass substrate 10 and the second glass substrate 30 is reduced enough for the s i l ano l groups of the first glass substrate 10 and the second glass substrate 30 to react. For example, the flatness of the fourth surface 32 of the second glass substrate 30 may be, but is not limited to, 0.01 μm, 0.5 μm, 1 μm, 5 μm, 10 μm, 20 μm, 30 μm, 40 μm, 50 μm, 60 μm, 70 μm,80 μm, 90 μm, 100 μm, and so forth. The roughness of the fourth surface 32 of the second glass substrate 30 may be, but is not limited to, 0.01nm, 0.5nm, 1nm, 5nm, 10nm, 20nm, 30nm, 40nm, 50nm, 60nm, 70nm, 80nm, 90nm, 100nm, etc. Optionally, the flatness of the fourth surface 32 of the second glass substrate 30 is 1 μm to 50 μm, and the roughness of the fourth surface 32 of the second glass substrate 30 is 1nm to 50nm, so as to ensure the processing precision of the first glass substrate 10 and the second glass substrate 30, thereby better achieving good adhesion between the first glass substrate 10 and the second glass substrate 30. The values of the roughness and the flatness of the fourth surface 32 of the second glass substrate 30 are merely for explanation, and are not particularly limited.

It will be appreciated that the first glass substrate 10 and the second glass substrate 30 according to the present application are connected together by the reactive groups on the glass surfaces without using an additional adhesive such as UV glue, so as to avoid the problem that the glue fills the first groove portion 132 to reduce the reflection effect and refraction effect of the light on the first texture 13. Wherein the kinds of the first glass substrate 10 and the second glass substrate 30 may be the same or different. The first glass substrate 10 and the second glass substrate 30 may include, but are not limited to, silicate glass (specifically, quartz glass, high silica glass, soda lime glass, aluminosilicate glass, borosilicate glass, etc.), borate glass, phosphate glass, etc., and other glasses suitable for use in housings of electronic devices are also suitable for use in the present application.

As can be appreciated, on the one hand, when the thickness of the first glass substrate 10 and the thickness of the second glass substrate 30 are too small, the processing of the first texturing 13 and the second texturing 33 is not facilitated, and the impact resistance is poor; on the other hand, when the sizes of the first texture 13 and the second texture 33 are too small, a spectroscopic phenomenon occurs, and the appearance effect of the moire cannot be exhibited, and when the sizes of the first texture 13 and the second texture 33 are too large, the condition of interference cannot be satisfied, and the appearance effect of the moire cannot be exhibited, and when the thickness of the first glass substrate 10 and the thickness of the second glass substrate 30 are constant, the overall structural strength is weakened. Optionally, to allow for ease of processing, high overall structural strength, and to ensure the reflection and refraction effects of light at the first and second textures 13 and 33. The thickness of the first glass substrate 10 is 0.45mm to 5.0mm, and the thickness of the second glass substrate 30 is 0.45mm to 5.0mm.

The depth of the first groove portion 132 and the depth of the second groove portion 332 may each independently be 3 μm to 50 μm. The thickness of the first glass substrate 10 and the thickness of the second glass substrate 30 may each be, but are not limited to, 0.45mm, 0.6mm, 0.9mm, 1.0mm, 2.0mm, 3.0mm, 4.0mm, 5.0mm, etc. The width W1 of the first and second protrusions 131 and 331 may be, but not limited to, 10 μm, 20 μm, 40 μm, 60 μm, 80 μm, 100 μm, 150 μm, 200 μm, 250 μm, 300 μm, etc. each independently. The width W2 of the first groove portion 132 and the width W2 of the second groove portion 332 may be, but are not limited to, 10 μm, 20 μm, 30 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, 100 μm, 110 μm, 120 μm, 130 μm, 140 μm, 150 μm, etc., respectively. The height H of the first and second protrusions 131 and 331 may be, but not limited to, 3 μm, 6 μm, 9 μm, 12 μm, 15 μm, 18 μm, 21 μm, 24 μm, 27 μm, 30 μm, 35 μm, 40 μm, 45 μm, 50 μm, etc. each independently. The depth of the first groove portion 132 and the depth of the second groove portion 332 may each be, but are not limited to, 3 μm, 6 μm, 9 μm, 12 μm, 15 μm, 18 μm, 21 μm, 24 μm, 27 μm, 30 μm, 35 μm, 40 μm, 45 μm, 50 μm, etc. The application only designs the width W1 of the first bulge 131, the width W1 of the second bulge 331, the width W2 of the first groove 132, the width W2 of the second groove 332, the height H of the first bulge 131, the height H of the second bulge 331, the depth of the first groove 132 and the depth of the second groove 332, so that the reflected light rays reflected by the first texture 13 and the second texture 33 can interfere, thereby presenting a moire appearance, more stereoscopic and gorgeous appearance, the decorative effect is better. The dimensions of the width W1 of the first protruding portion 131, the width W1 of the second protruding portion 331, the width W2 of the first recessed portion 132, the width W2 of the second recessed portion 332, the height H of the first protruding portion 131, the height H of the second protruding portion 331, the depth of the first recessed portion 132, and the depth of the second recessed portion 332 are merely for illustration, and the dimensions of the specific structures of the first glass substrate 10 and the second glass substrate 30 may be designed according to the actual product requirements without being particularly limited.

The first protruding portions 131 and the first recessed portions 132 are alternately arranged along a predetermined direction (i.e., the X-axis direction), that is, one first recessed portion 132 is connected between two adjacent first protruding portions 131. The second protruding portions 331 and the second recessed portions 332 are alternately arranged along a predetermined direction (i.e., the X-axis direction), that is, one second recessed portion 332 is connected between two adjacent second protruding portions 331. The number of the first protrusion 131, the first groove 132, the second protrusion 331, and the second groove 332 may each independently include a plurality. The plurality of first protruding portions 131 and the plurality of first groove portions 132 may be arranged in an array, and the plurality of second protruding portions 331 and the plurality of second groove portions 332 may be arranged in an array, so that the decoration 100 has a continuous light effect. Illustratively, in the present embodiment, the shape, the size and the arrangement of the first protruding portion 131 of the first texture 13 and the second protruding portion 331 of the second texture 33 are the same, and the shape, the size and the arrangement of the first recessed portion 132 of the first texture 13 and the second recessed portion 332 of the second texture 33 are also the same. In some embodiments, at least one of the shape, size, and arrangement of the first protrusions 131 of the first texture 13 and the second protrusions 331 of the second texture 33 may be different; and/or at least one of the shape, size, and arrangement of the first groove portion 132 of the first texturing 13 and the second groove portion 332 of the second texturing 33 may be different.

The first boss 131 includes a connection end surface 211 that is sealingly connected to the second glass substrate 30. The connection end surface 211 is parallel to the fourth surface 32 of the second texture structure 33, thereby facilitating the connection between the first protrusion 131 and the second glass substrate 30, and the connection end surface 211 can better support the second glass substrate 30, thereby improving the stability and reliability of the overall structural strength of the decoration 100. The first boss 131 further includes a connection side 212 connected to an edge of the connection end surface 211. Illustratively, in the present embodiment, the connection end face 211 and the fourth surface 32 of the second glass substrate 30 are both configured to be planar, thereby facilitating the fitting of the first glass substrate 10 and the second glass substrate 30. The connection side 212 may be configured as a plane or a curved surface. The connecting side surface 212 is bent and arranged opposite to the connecting end surface 211, so that the number of reflection and refraction times of light rays is increased, and the brightness of the light and shadow presented by the decoration 100 is further enhanced. The connection side 212 and the connection end 211 are arranged in a rounded shape, so that the problems of scratch and scratch of the first glass substrate 10 and the second glass substrate 30 in the assembly process are avoided.

Alternatively, in some embodiments, the width W3 of the connection end face 211 in the width direction of the garnish 100 is 20 μm to 40 μm, thereby securing the connection strength between the first boss 131 and the second glass substrate 30. For example, in some embodiments, the width W3 of the connection end face 211 may be, but is not limited to, 20 μm, 25 μm, 30 μm, 35 μm, 40 μm, or the like. The width W3 of the connection end surface 211 is merely for illustration, and is not particularly limited, and the width W3 of the connection end surface 211 may be designed according to the actual product requirement.

The first groove portion 132 of the first texture 13 and the fourth surface 32 of the second texture 33 form a first inner space 201. The second groove portion 332 of the second texturing 33 is configured as the outer space 202. Specifically, the first groove portion 132 and the second groove portion 332 each independently include a groove bottom wall 221 and a groove side wall 222 connected to the groove bottom wall 221. In the present embodiment, the connection side face 212 of the first convex portion 131 serves as the groove side wall 222 of the first groove portion 132. The groove bottom wall 221 and the groove side wall 222 of the first groove portion 132 of the first texturing 13 form a first inner space 201 together with the fourth surface 32 of the second texturing 33. The groove side walls 222 and the groove bottom walls 221 of the second groove portions 332 of the second texturing 33 together form an upwardly open outer space 202. In this way, the second texture structure 33 is located between the second surface 12 of the first glass substrate 10 and the fourth surface 32 of the second glass substrate 30, and the first inner space 201 is not interfered by other functional layers, so as to avoid the distortion of the light in the second texture structure 33, and further ensure that the second texture structure 33 generates a better light effect.

In some embodiments, the groove bottom wall 221 forms an angle α with the groove side wall 222 of 10 ° -90 °. For example, in some embodiments, the included angle α may be, but is not limited to, 10 °, 20 °, 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, 90 °, etc. It should be noted that the value of the included angle α is only for illustration, and is not limited to a specific limitation, and the included angle α may be designed according to the requirements of actual products. Illustratively, in the present embodiment, the groove bottom wall 221 and the groove side wall 222 form an angle α of 45 ° therebetween, so that the first and second textures 13 and 33 are ensured to have strong light reflectivity to enhance the light-shadow brightness of the trim piece 100.

Illustratively, in the first embodiment, the orthographic projections of the first texture 13 and the second texture 33 in the thickness direction of the decoration 100 do not completely overlap, so that the reflected light reflected by the first texture 13 and the reflected light reflected by the second texture 33 interfere to generate moire, thereby making the decoration 100 exhibit a more dazzling and stereoscopic appearance decoration effect, and improving the use effect and decoration effect of the decoration 100. Specifically, the orthographic projections of the first convex portion 131 of the first texture 13 and the second concave portion 332 of the second texture 33 in the thickness direction of the garnish 100 are disposed at least partially overlapping. The orthographic projection portions of the first protrusions 131 of the first texturing 13 and the second groove portions 332 of the second texturing 33 partially overlap or completely overlap in the thickness direction of the garnish 100.

Specifically, according to the interference principle, interference is a phenomenon in which two or more columns of waves overlap when they overlap in space, thereby forming a new waveform. In particular, in the decoration 100 according to the present application, when light irradiates the first texture 13 and the second texture 33 on the decoration 100, because the surface of the first texture 13 and the surface of the second texture 33 are uneven, there is a difference in the optical path length between the reflected light at different positions of the first texture 13 and/or the second texture 33, so that interference occurs between the reflected light at different positions of the first three-dimensional texture, for example, interference occurs between the reflected light at different positions of the second three-dimensional texture, interference also occurs between the reflected light reflected by the first texture 13 and the reflected light reflected by the second texture 33, and the outer surface of the decoration 100 may exhibit bright and dark fringes, i.e., moire fringes, due to the interference of the double-layer textures of the first texture 13 and the second texture 33, thereby forming a special appearance effect. The specific shape and arrangement of the mole patterns can be adjusted according to the shape and arrangement of the first texture 13 and the second texture 33.

Illustratively, in the present embodiment, the first texture 13 and the second texture 33 are identical in structure, and the second protrusions 331 of the second texture 33 are displaced by 1% -99% relative to the first protrusions 131 of the first texture 13 in a predetermined direction, so as to facilitate processing, and ensure stronger interference between the reflected light reflected by the first texture 13 and the reflected light reflected by the second texture 33, resulting in clear moire. In some embodiments, the first texture 13 and the second texture 33 may be configured differently, such as in a different shape, size, or arrangement. The second protrusions 331 of the second texturing 33 are displaced by 1%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% or 99% and so on with respect to the first protrusions 131 of the first texturing 13 in a predetermined direction. It should be noted that the displacement dimension of the second texture structure 33 relative to the first texture structure 13 in the width direction of the decoration 100 is merely for illustration, and is not particularly limited, and may be designed according to the actual product requirement. Illustratively, in the present embodiment, the second protruding portion 331 of the second texturing 33 is displaced 45% in the width direction of the garnish 100 with respect to the first protruding portion 131 of the first texturing 13, that is, the second texturing 33 is displaced by a distance that is half of the sum of the width of the first protruding portion 131 and the width of the first recessed portion 132.

In the second embodiment, the structure of the decoration 200 is similar to that of the decoration 100, and the second embodiment focuses on the description of the structural details of the differences from the decoration 100 in the first embodiment, and the remaining structural details are not described herein. Specifically, the decoration 200 includes the first glass substrate 10 and the second glass substrate 30 having the same structure, and the orthographic projections of the first texture 13 and the second texture 33 in the thickness direction of the decoration 200 are completely overlapped. The first convex portion 131 of the first texturing 13 and the second concave portion 332 of the second texturing 33 abut in orthographic projection in the thickness direction of the garnish 200. The orthographic projections of the first convex portion 131 of the first texturing 13 and the second convex portion 331 of the second texturing 33 in the thickness direction of the garnish 200 are overlapped, and the orthographic projections of the first concave portion 132 of the first texturing 13 and the second concave portion 332 of the second texturing 33 in the thickness direction of the garnish 200 are also overlapped.

According to the application, the first texture structure 13 and the second texture structure 33 which are arranged in a stacked manner at intervals are respectively arranged on the first glass substrate 10 and the second glass substrate 30, so that the contact area between incident light rays and the first texture structure 13 and the second texture structure 33 is increased, the reflection and refraction times of the light rays on the first texture structure 13 and the second texture structure 33 can be increased, the light intensity inside the decoration 200 is increased, the brightness of the decoration pattern part of the decoration 200 is more highlighted, and the use effect and the decoration effect of the decoration 200 are improved.

Referring to fig. 1 and 3 together, fig. 3 is a cross-sectional view of a decoration 300 according to a third embodiment of the present application. In the third embodiment, the decoration 300 is similar to the structure of the decoration 100, and the focus of the third embodiment is on the structural details of the differences from the decoration 100 in the first embodiment, and the rest of the structural details are not described herein. Specifically, the trim piece 300 also includes a third glass substrate 50. The second glass substrate 30 is located between the first glass substrate 10 and the third glass substrate 50. The third glass substrate 50 is bonded to the second glass substrate 30, and the second glass substrate 30 is bonded to the first glass substrate 10. The third glass substrate 50 includes oppositely disposed fifth and sixth surfaces 51, 52. The fifth surface 51 of the third glass substrate 50 is provided with a third texture 53. The sixth surface 52 of the third glass substrate 50 is sealingly connected to the second texture 33.

The first protrusions 131 of the first glass substrate 10 are sealingly connected to the fourth surface 32 of the second glass substrate 30 to achieve a first interior space 201 between two adjacent first textures 13 between the first glass substrate 10 and the second glass substrate 30. Specifically, the first groove portion 132 of the first texture 13 and the fourth surface 32 of the second glass substrate 30 form a first inner space 201. The second raised portions 331 of the second texture feature 33 are sealingly connected to the sixth surface 52 of the third glass substrate 50. A second inner space 203 between two adjacent second textures 33 is formed between the second glass substrate 30 and the third glass substrate 50. Specifically, the second groove portion 332 of the second glass substrate 30 surrounds the sixth surface 52 of the third glass substrate 50 to form the second internal space 203. The third texturing 53 includes a plurality of third protrusions 531 and a plurality of third groove portions 532 connected to the plurality of third protrusions 531. The third groove portion 532 of the third glass substrate 50 is configured as the outer space 202, i.e., the third groove portion 532 of the third glass substrate 50 is a semi-open groove.

It is to be appreciated that in some embodiments, the trim piece 300 can include a plurality of third glass substrates 50. The plurality of third glass substrates 50 are stacked one on top of the other in the thickness direction of the garnish 300. The number of the third glass substrates 50 is merely for illustration, and is not particularly limited.

In some embodiments, the orthographic projections of at least two of the first texture 13, the second texture 33, and the third texture 53 in the thickness direction of the trim piece 300 do not completely overlap. Wherein at least one of the first convex portion 131 of the first texture 13 and the second convex portion 331 of the second texture 33 at least partially overlaps with the orthographic projection of the third groove portion 532 of the third texture 53 in the thickness direction of the garnish 300.

Specifically, exemplarily, in the present embodiment, the structure of the third glass substrate 50 is the same as that of the first glass substrate 10. At this time, the third texture 53 completely overlaps with the orthographic projection of the first texture 13 in the thickness direction of the garnish 300, that is, the third groove portion 532 of the third texture 53 abuts with the orthographic projection of the first protrusion portion 131 of the first texture 13 in the thickness direction of the garnish 300. The orthographic projections of the third texture structure 53 and the second texture structure 33 in the thickness direction of the decoration 300 do not completely overlap, that is, the orthographic projections of the third groove portion 532 of the third texture structure 53 and the first protrusion portion 131 of the first texture structure 13 and the second protrusion portion 331 of the second texture structure 33 in the thickness direction of the decoration 300 may partially overlap or completely overlap, so that the reflected light reflected by the second texture structure 33 can interfere with the mole patterns generated by the reflected light reflected by the first texture structure 13 and the reflected light reflected by the third texture structure 53, respectively, so that the interference effect of the three texture structures of the first texture structure 13, the second texture structure 33 and the third texture structure 53 is stronger, and the decoration effect of the decoration 300 is further improved.

In some embodiments, the structures of the first texture 13, the second texture 33, and the third texture 53 may all be different, such as different shapes, different sizes, or different arrangements. At this time, the orthographic projections of at least two of the first texture 13, the second texture 33, and the third texture 53 in the thickness direction of the garnish 300 do not completely overlap each other. In other embodiments, the structures of the first texture 13, the second texture 33, and the third texture 53 may be identical, for example, identical in shape, identical in size, or identical in arrangement. At this time, the orthographic projections of the first texture 13, the third texture 53, and the third texture 53 in the thickness direction of the garnish 300 are completely overlapped. The first protrusion 131 of the first texture 13 and the second protrusion 331 of the second texture 33 are adjacent to the third groove 532 of the third texture 53 in the orthographic projection in the thickness direction of the decoration 300.

Referring to fig. 5 and fig. 6 together, fig. 5 is a flowchart of a method for manufacturing a decoration according to an embodiment of the present application, and fig. 6 is a schematic diagram of a manufacturing process of a decoration according to a first embodiment of the present application. The preparation method of the decoration comprises the following steps.

And S51, etching the first glass to be processed to obtain a first glass substrate.

The first glass to be processed 1 comprises a first surface 11 and a second surface 12 arranged opposite to each other. The first glass to be processed 1 is subjected to an etching treatment to obtain a first glass substrate 10, specifically comprising: coating and curing a photoresist layer on the first surface 11 of the first glass to be processed 1; developing the exposed photoresist layer; the first glass to be processed 1 after the development exposure is subjected to etching treatment to obtain a first glass substrate 10. Wherein the first surface 11 of the first glass to be processed 1 is etched with a first texture 13.

The thickness of the photoresist layer is 2um-9um, the curing temperature of the photoresist layer is 80 ℃ to 120 ℃, and the curing time of the photoresist layer is 2 min-6 min. The application can adopt laser direct exposure or film shielding exposure photoresist layer to obtain ideal pattern shape. In some embodiments, the etching reagent includes, but is not limited to, aqueous solutions of hydrofluoric acid, sulfuric acid. Wherein, the mass ratio of hydrofluoric acid, sulfuric acid and water can be 8-15:2-10: the etching time can be 5min-10min, 50-100. In other embodiments, the etching reagent includes, but is not limited to, an aqueous solution of the new synthetic Fuli polishing solution XHL-B4020. Wherein the mass ratio of XHTML-B4020 to water is 1-2:1-2, the etching temperature can be 25-28 ℃, and the etching time can be 1-10 min.

In some embodiments, prior to performing step S51, the method of preparing further comprises: a protective layer is applied to the second surface 12 of the first glass to be processed 1. The protective layer is acid-resistant thermosetting ink, so that the second surface 12 of the first glass to be processed 1 is prevented from being scratched in the processing process and from being damaged in the etching process of the first surface 11 of the first glass to be processed 1, further the second surface 12 of the first glass to be processed 1 is ensured to have a flat surface, and decoration such as film pasting and spraying is facilitated.

In some embodiments, after performing step S51, the preparation method further comprises: removing the protective layer and the photoresist layer on the first glass substrate 10; the first glass substrate 10 is cleaned and surface activated.

A stripping process is used to remove the protective layer and photoresist layer from the first glass substrate 10. Specifically, an alkaline solution is used for ultrasonic soaking and rinsing. The alkaline solution includes, but is not limited to, naOH solution or KOH solution. Wherein the mass concentration of the alkaline solution is 8% -20%. The temperature of ultrasonic soaking treatment is 25-90 ℃, and the time of ultrasonic soaking treatment is 10-30 min.

The cleaning step comprises the following steps: the first glass substrate 10 is subjected to a cleaning process using a cleaning solution. Specifically, the first glass substrate 10 is subjected to a soaking and washing treatment with a washing solution. For example, the first glass substrate 10 is soaked and washed with a washing mixed solution of 0.1-5% Na2CO3, 1-10% NaOH, 0.1-0.5% sodium alkyl benzene sulfonate, 5-15% ethanol, 1-5% fatty alcohol polyoxyethylene ether and 64.5-92.8% H2O, and then is soaked and washed with 1-10% NaOH solution by ultrasound. Wherein the temperature of ultrasonic soaking treatment is 25-90 ℃, the time of ultrasonic soaking treatment is 2-6 min, and the frequency of ultrasonic soaking treatment is 1000-5000 HZ. The cleaning step is aimed at removing the acid and the products remaining on the surface of the first glass substrate 10 to ensure the surface of the first glass substrate 10 to be clean. The washing solution is an alkaline solution. Alternatively, naOH in the wash solution may be replaced with KOH at the same concentration and Na2CO3 in the wash solution may be replaced with K2CO3 at the same concentration. It will be appreciated that the wash solution may include, but is not limited to, the above-described components, and that the wash solution may be selected from materials commonly used in the art of glass manufacturing processes, and the present application is not particularly limited.

The surface activation treatment step comprises the following steps: the first glass substrate 10 after the cleaning treatment is subjected to an activation treatment with a surfactant. Wherein the surfactant includes but is not limited to at least one of alkaline solution, acidic solution, and plasma.

In some embodiments, the surfactant is an alkaline solution. For example, the surface activation treatment of the first glass substrate 10 specifically includes the steps of: the first glass substrate 10 is subjected to a surface activation treatment with an alkaline solution, i.e., the first glass substrate 10 is immersed in the alkaline solution. Illustratively, in the first step, the first glass substrate 10 after the cleaning treatment is subjected to ultrasonic soaking treatment by using a mixed solution of 1% -10% of NaOH, 0.1% -5% of C6H15NO3 (triethanolamine), 0.1% -3% of Na2CO3, 0.05% -1% of sodium dodecyl benzene sulfonate (C18H 29NaO 3S), 0.1% -5% of fatty alcohol polyoxyethylene ether (AEO) and 66% -97.4% of H2O, and then is rinsed by pure water. Wherein the temperature of the ultrasonic soaking treatment is 25-90 ℃, the time of the ultrasonic soaking treatment is 2-6 min, and the ultrasonic frequency of the ultrasonic soaking treatment is 1000-5000 HZ. And secondly, carrying out ultrasonic soaking treatment on the first glass substrate 10 by adopting 1% -10% NaOH, and then flushing by adopting pure water. Wherein the temperature of the ultrasonic soaking treatment is 60 ℃, the time of the ultrasonic soaking treatment is 3min, and the frequency of the ultrasonic soaking treatment is 3000HZ. The surface activation treatment aims to increase the number of silicon hydroxyl groups on the surface of the first glass substrate 10 and enhance the hydrophilic capacity of the surface of the first glass substrate 10. Alternatively, the water drop angle of the activated surface is not more than 10 degrees, thereby facilitating the hot-melt process in step S53.

It will be appreciated that in some embodiments, naOH in the surfactant may be replaced with KOH at the same concentration, and Na2CO3 in the surfactant may be replaced with K2CO3 at the same concentration. The alkaline solution of NaOH or KOH contained in the surfactant can react with the sub-surface layer existing on the surface of the glass matrix, so that the bond breakage on the surface of the glass matrix is increased, and a large number of E groups and D groups are generated, wherein the thickness of the sub-surface layer is about 1 mu m, and the sub-surface layer has higher activity and porous characteristics; the E group is a [ SiO4] -group, and the D group is a [ SiO3] + group. It can be understood that the D group absorbs OH-in the solution besides water molecules, and the hydroxyl ions are polar covalent bonds, so that the water molecules are easier to absorb, in addition, the E group and the D group react with the absorbed water molecules to form s i l ano l groups (namely-Si-O-H groups), s i l ano l groups also absorb water molecules, and the water molecules absorbed by the surface of the glass substrate obtained by the alkaline process are thick and water-hydrated layers.

In other embodiments, the surfactant is an acidic solution. For example, the surface activation treatment of the first glass substrate 10 specifically includes the steps of: the first glass substrate 10 is subjected to a surface activation treatment with an acidic solution, i.e., the first glass substrate 10 is immersed in the acidic solution. Illustratively, in a first step, the cleaned first glass substrate 10 is ultrasonically immersed and rinsed with a mixture of 1% -5% hf, 1% -10% h3po4, 0.5% -10% hno3, and 75% -97.25% h2 o. Wherein the temperature of the ultrasonic soaking treatment is normal temperature, the time of the ultrasonic soaking treatment is 1s-30s, and the frequency of the ultrasonic soaking treatment is 1000HZ-5000HZ. In the second step, the first glass substrate 10 is subjected to ultrasonic soaking and washing treatment by adopting 1% -10% HCL treatment. Wherein the temperature of the ultrasonic soaking treatment is normal temperature, the time of the ultrasonic soaking treatment is 2-6 min, and the frequency of the ultrasonic soaking treatment is 1000-5000 HZ.

It will be appreciated that HF may clean the first and second surfaces 11, 12 of the first glass substrate 10, remove the subsurface layers of the first glass substrate 10, increase the relative area of the first and second surfaces 11, 12 of the first glass substrate 10, and cooperate with H3PO4 and HNO3 to substantially break the silicon oxygen bonds and silicon bonds to form E and D groups. In an acidic environment, a large number of H+ groups exist, the H+ groups are combined with part of E groups, and in addition, the E groups and the D groups react with adsorbed water molecules to form s i l ano l groups and adsorb water molecules to form. Under the further action of HCL, the E group and the D group are continuously converted to form s i l ano l groups, the-OH group combined in an acidic environment is neutral, less water molecules are adsorbed, and the formed hydration layer is thinner and thinner. It should be noted that, the process of performing the surface activation treatment on the first glass substrate 10 with the acidic solution requires strict control of the soaking time, which would damage the flatness and roughness of the first glass substrate 10.

It can be understood that the purpose of the acidic solution and the alkaline solution treatment is to greatly increase the number of reactive groups-silicon hydroxyl groups on the first surface 11 and the second surface 12 of the first glass substrate 10, enhance the hydrophilicity of the first surface 11 and the second surface 12 of the first glass substrate 10, form a water film layer on the first surface 11 and the second surface 12 of the treated first glass substrate 10, and better protect the silicon hydroxyl groups.

In other embodiments, the surfactant employs a plasma. For example, the surface activation treatment of the first glass substrate 10 specifically includes the steps of: the first glass substrate 10 is subjected to a surface activation treatment using plasma. Illustratively, the plasma of this embodiment employs nitrogen. Wherein the surface activation treatment time is 5min-30min, and the vacuum degree is 0.1MPa-10MPa.

In some embodiments, the plasma may also be, but is not limited to, argon, oxygen, and other types of gases. The plasma surface treatment can perform physical bond breaking and chemical embedding on glass to obtain [ SiO4] -groups and [ SiO3] + groups which have similar treatment effects to acid and alkali liquid medicine, water with a certain temperature is used for soaking and assisting ultrasound to facilitate the two groups to adsorb water molecules to form s i l ano l groups, water molecules are continuously adsorbed to form a hydration layer, and compared with the two previous chemical treatment methods, the method for performing surface activation treatment on the plasma has the advantages that the number of silicon hydroxyl groups is minimum, the adsorbed water molecules are the least, the method is the most convenient and quick, the production rate is improved, and the production process is simplified.

It will be appreciated that the surfactant may include, but is not limited to, the above components, and the surfactant may be selected from materials commonly used in the art of glass manufacturing processes, and the present application is not particularly limited. In some embodiments, the second glass substrate 3 or the second glass substrate 30 to be processed, which is attached to the first glass substrate 10, may also be subjected to the above-mentioned cleaning and surface activation treatment to further enhance the attaching stability and reliability between the glasses, which will not be described herein.

And S53, attaching the second glass substrate to the first glass substrate to obtain the decoration. The decoration comprises a first glass matrix and a second glass matrix, wherein the first glass matrix and the second glass matrix are combined into a whole; the second glass substrate is attached to the first glass substrate, the first glass substrate comprises a first surface and a second surface which are oppositely arranged, and the second glass substrate comprises a third surface and a fourth surface which are oppositely arranged; the first surface is provided with a first texture structure, and the third surface is provided with a second texture structure; the fourth surface of the second glass substrate is in sealing connection with the first texture structures, and a first inner space between two adjacent first texture structures is formed between the first glass substrate and the second glass substrate.

In some embodiments, attaching the second glass substrate to the first glass substrate specifically includes: pre-attaching the second glass to be processed and the first glass matrix to obtain a first glass composite; performing hot pressing treatment on the first glass composite body; and etching the second glass to be processed in the first glass composite body after the hot pressing treatment to obtain the second glass matrix.

The second glass 3 to be processed includes a third surface 31 (i.e., the third surface 31 of the second glass substrate 30) and a fourth surface 32 (i.e., the fourth surface 32 of the second glass substrate 30) that are disposed opposite to each other. According to the embodiment of the application, the second glass 3 to be processed is attached to the first glass substrate 10, and then the second glass 3 to be processed is etched to form a second texture structure, on one hand, because the third surface 31 of the second glass 3 to be processed is configured as a flat surface, the hot pressing treatment of the second glass 3 to be processed and the first glass substrate 10 is facilitated, so that the attaching stability and reliability of the second glass 3 to be processed and the first glass substrate 10 are realized, the phenomena of bubbles or spots and the like are avoided from being formed between the second glass 3 to be processed and the first glass substrate 10, and the decorative effect is enhanced; on the other hand, the phenomenon of damaging the second texture structure 33 in the hot pressing step is avoided, so that the integrity of the second texture structure is protected conveniently, the second texture structure 33 is ensured to present a good light and shadow effect, and the visual effect of the decoration is improved.

In some embodiments, the attaching the second glass substrate to the first glass substrate specifically includes: etching the second glass to be processed to obtain a second glass matrix; and pre-attaching the second glass substrate and the first glass substrate, and performing hot pressing treatment to obtain the decoration.

According to the embodiment of the application, the second glass 3 to be processed is etched to form the second texture structure, and then the second glass substrate 30 containing the second texture structure is attached to the first glass substrate 10, so that on one hand, the problem that the structure of the first glass substrate 10 is damaged when the third surface 31 of the second glass 3 to be processed is etched is avoided, and the second surface 12 of the first glass substrate 10 and the fourth surface 32 of the second glass substrate 30 are ensured to be flat surfaces; on the other hand, the first glass to be processed 1 and the second glass to be processed 3 can be simultaneously subjected to etching treatment without coating a shielding layer on the second surface 12 of the first glass substrate 10 during the etching treatment of the second glass to be processed 3, thereby improving the processing efficiency of the first glass substrate 10 and the second glass substrate 30 and improving the production efficiency of the decorating parts.

The pre-lamination treatment between the glass sheets may be performed by an atmospheric pressure air discharge method. In some embodiments, an air bleed is used to exclude air layers between the glasses. The evacuation device is, for example, but not limited to, a vacuum device. In other embodiments, glass is placed in a solution to remove air layers between the glass. The pre-bonding treatment of the second glass substrate 3 to be processed and the first glass substrate 10 will be described below as an example. Placing the second glass to be processed 3 and the first glass substrate 10 together, and applying preset pressure by adopting an exhaust device to remove an air layer between the second glass to be processed 3 and the first glass substrate 10; or the second glass to be processed 3 and the first glass substrate 10 are placed in a solution to remove an air layer between the second glass to be processed 3 and the first glass substrate 10 by affinity of water and atmospheric pressure, and to obtain an integrated second glass composite. Wherein a transition layer is formed between the second glass to be processed 3 and the first glass substrate 10, and the thickness of the transition layer is 0.01 μm-100 μm. The solution may include, but is not limited to, pure water, a surfactant, etc., and the present application is not particularly limited.

It can be appreciated that the advantage of using the exhaust device to remove the air layer with the preset pressure is that the waiting time is short, the production cycle can be greatly shortened, but the yield is low, and the yield is mainly reflected in the problems of fantasy color, bright spots caused by particle points and the like caused by the gap between the second glass to be processed 3 and the first glass substrate 10. The solution is used for removing the air layer with high yield, but the treatment time is long. Preferably, in some embodiments, the air layer may be removed by using both an air exhaust device and a solution, so as to solve the problems of long processing time and bright spots caused by fantasy colors, particle spots, etc. caused by a gap between the second glass to be processed 3 and the first glass substrate 10.

Wherein the flatness of the fourth surface 32 of the second glass 3 to be processed (i.e., the fourth surface 32 of the second glass substrate 30) is 0.01 μm to 100 μm and the roughness is 0.01nm to 100nm. The smaller the flatness value and the smaller the roughness value of the joint between the second glass to be processed 3 and the first glass substrate 10 are, the more advantageous the integration between the second glass to be processed 3 and the first glass substrate 10 is. The principle of the pre-lamination treatment process is that the second glass 3 to be processed is discharged with air on the premise of ensuring the flatness and roughness of the fourth surface 32, the second glass 3 to be processed and the first glass substrate 10 are tightly pressed together by atmospheric pressure, at this time, the distance between the second glass 3 to be processed and the first glass substrate 10 is reduced to be enough s i l ano l groups for reaction, and as s i l ano l groups absorb water molecules to form a hydration layer, the first glass composite formed by pre-lamination treatment of the second glass 3 to be processed and the first glass substrate 10 is difficult to enable s i l ano l groups to fully undergo a combination reaction at normal temperature and baking temperature.

The principle of the hot pressing treatment process is that a large amount of unreacted hydroxyl groups exist on the glass combination surface of the first glass composite body, so that the hot pressing treatment process has higher activity, the hydroxyl groups are removed at a higher temperature to enable the second glass to be processed 3 and the first glass substrate 10 to form integrated hollow glass, and the hydration layer with the thickness of 0.1-20 mu m exists on the glass combination surface, so that the condition that the bonding strength is reduced due to incomplete reaction of the hydration layer can be prevented, and the thickness of a transition layer of the second glass to be processed 3 and the first glass substrate 10 can be properly pressurized to be reduced; the pressurizing step of the hot pressing treatment is favorable for combining the second glass to be processed 3 and the first glass substrate 10 into a whole, reduces stress concentration and transition layer-to-layer spacing, and enhances the bonding strength. Wherein the temperature of the hot pressing treatment is 350-750 ℃, the pressure of the hot pressing treatment is 0.01-10 Mpa, and the time of the hot pressing treatment is 150-330 min. For example, the heat press is performed at a temperature of 350 ℃, 400 ℃, 450 ℃, 500 ℃, 550 ℃, 600 ℃, 650 ℃, 700 ℃, 750 ℃, or the like, and the heat press is performed at a pressure of 0.01Mpa, 0.1Mpa, 0.4Mpa, 0.8Mpa, 1Mpa, 2Mpa, 3Mpa, 4Mpa, 5Mpa, 6Mpa, 7Mpa, 8Mpa, 9Mpa, 10Mpa, or the like, and the heat press is performed for a time of 150min, 180min, 210min, 240min, 270min, 300min, 330min, or the like. The temperature, pressure, and time of the autoclave are merely illustrative, and are not particularly limited.

Optionally, in this embodiment, performing the hot press treatment on the first glass composite specifically includes: heating the first glass composite to 400-800 ℃ at a heating rate of 2-10 ℃/min, preserving heat for 10-30 min, maintaining the pressure at 0.2-5 MPa, and then cooling to room temperature at a cooling rate of 2-10 ℃/min.

In some embodiments, the method of making further comprises: and polishing the first glass composite body after the hot pressing treatment, so that adverse effects of stamping, pitting, scratch and the like on the first glass composite body caused by the hot pressing treatment are eliminated. For example, the embodiment of the application adopts polishing equipment and polishing powder to polish the first glass composite body after the hot pressing treatment. Among them, various glass polishing powders commonly used in the art, such as, but not limited to, cerium oxide, can be used as the polishing powder.
