In one aspect of the present application, the present application provides a method of making a curved glass sheet. According to an embodiment of the present application, referring to FIG. 1, the method includes:

S100: forming a first texture surface

In this step, the planar glass sheet is subjected to a first treatment to form a first textured surface on the flat glass sheet. According to the embodiment of the present application, the shape, size, and thickness of the flat glass plate are not particularly limited, and those skilled in the art can make selections as needed. For example, according to an embodiment of the present application, the process of trimming a flat glass sheet may be further included before the first treatment of the flat glass sheet. According to a specific embodiment of the present application, in the process, a flat glass plate can be cut using a numerically controlled machine tool and a diamond cutter to obtain a flat glass plate of a predetermined size. According to an embodiment of the present application, the method of the first process is not particularly limited, and may be dry etching, wet etching, or setting a pattern layer. According to an embodiment of the present application, a first treatment may be performed on at least a portion of the surface of the planar glass sheet to form a first textured surface on at least a portion of the surface of the planar glass sheet.

According to an embodiment of the present application, the dry etching may include at least one of a laser laser etching process, a plasma etching process, and a photolithography process. The following is a brief description of each specific method of dry etching:

According to an embodiment of the present application, the first textured surface may be formed by laser laser engraving. The high-intensity laser beam emitted by the laser can be used to focus on the focus to change the surface properties of the material, thereby forming a pattern to be etched on the surface of the material. For example, according to a specific embodiment of the present application, when the dry etching is laser laser engraving, an ultraviolet laser engraving device may be used, and the laser light source may be ultraviolet light, and the etching power may be 5-10W. Therefore, the first textured surface can be formed on the flat glass plate simply and quickly, and the shape of the first textured surface and the etching depth can also be easily passed through parameters such as the laser light source, the etching path, and the laser etching power. Make adjustments.

According to an embodiment of the present application, the first textured surface may be formed by a plasma etching process. Thereby, the plasma generating device can be used to generate plasma, and the free radicals in the plasma can bombard or sputter the surface molecules of the etched material to form a volatile substance, thereby achieving the purpose of etching. According to a specific embodiment of the present application, when the first textured surface is formed by plasma etching, a mask may be previously disposed on the flat glass plate to define a region where the plasma can act, thereby realizing the first textured surface. The location is limited. Alternatively, a template having a certain hollow pattern may be used as a mask, and a first textured surface having a specific pattern may be obtained.

In summary, the dry etching method can have various options and is convenient to operate. According to the embodiment of the present application, the specific method and operating parameters of the dry etching are not particularly limited as long as the surface of the flat glass plate can be etched to form a texture. According to an embodiment of the present application, the etching depth of the dry etching may be 0.01-1 mm. The range of the etch depth facilitates the formation of textures of different depths and ensures that the etched planar glass sheet still has good mechanical strength.

According to further embodiments of the present application, the first textured surface may also be formed by wet etching. Specifically, the flat glass plate may be etched by using an etching solution, that is, the flat glass plate is immersed in the etching liquid for etching. According to an embodiment of the present application, the wet etching may include the following specific steps: first, a mask is provided on the surface of the flat glass plate. The specific manner of setting the mask is not particularly limited. For example, a photosensitive ink may be printed on the surface of the flat glass plate, and a mask may be formed using the photosensitive ink to shield the flat glass plate region which is not required to be etched. Next, the side of the flat glass plate provided with the mask can be placed in the etching liquid for etching. According to the embodiment of the present application, the kind of the etching liquid and the specific etching manner are not particularly limited as long as the etching texture can be formed on the flat glass plate, for example, according to a specific embodiment of the present application, printing can be performed. The flat glass plate which shields the ink is immersed in an etching solution mainly composed of hydrofluoric acid for etching. The mask is finally removed to form an etched texture pattern. According to an embodiment of the present application, a masked ink can be removed by using a specific weakly alkaline (concentration: 1-5%) solution, whereby the flat glass plate of the ink shielding region is not etched, is a transparent gloss effect, and is etched. The flat glass plate area is matte matte effect. Thus, the etched flat glass sheet not only has a textured effect, but also has good mechanical strength.

According to other embodiments of the present application, the first textured surface may also be formed by providing a pattern layer. The provision of the pattern layer may be achieved by at least one of an ultraviolet imprint process, a hot imprint process, and 3D printing. For example, the first textured surface may be formed by ultraviolet imprinting, specifically: the ultraviolet curable adhesive is coated on the surface of the flat glass plate, and a transparent stamper is disposed on the ultraviolet curable adhesive, and the embossed area is promoted by ultraviolet exposure. The UV curable adhesive is polymerized and solidified to form a textured pattern. Alternatively, the first textured surface may be formed by a hot stamping process. Specifically, the stamper may be pressed against the polymer film on the substrate under high temperature and high pressure, and then the temperature is lowered, and then the stamper is separated from the polymer layer. And forming a texture pattern. Alternatively, the first textured surface may be formed by 3D printing. Specifically, the texture pattern may be formed by layer-by-layer printing using a bondable material such as powdered metal or plastic based on the digital model file. Thus, the method of setting the pattern layer can have various options and is convenient to operate. According to the embodiment of the present application, the specific method and operational parameters for providing the pattern layer are not particularly limited as long as the texture can be formed on the surface of the flat glass plate. For example, the ultraviolet imprint process may be used to provide a pattern layer on the surface of the flat glass plate. Specifically, the ultraviolet curable glue may be first imprinted on the glass substrate through the mold texture, and then the texture effect is exhibited by the post-stage coloring process. According to an embodiment of the present application, the side of the pattern layer away from the flat glass plate has a stripe pattern having a width of 0.01 to 1 mm.
