Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings.Below with reference to
The embodiment of accompanying drawing description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
In one aspect of the invention, the present invention proposes a kind of method for preparing bend glass sheet material.According to the present invention
Embodiment, with reference to figure 1, this method includes：
S100：Form the first texture face
In this step, wet etching treatment is carried out to flat glass plate, to form the first line on flat glass plate
Reason face.According to an embodiment of the invention, the shape of flat glass plate, size and thickness are not particularly limited, people in the art
Member can be selected as needed.For example, according to an embodiment of the invention, the first processing can be being carried out to flat glass plate
Before, the process that material is cut out to flat glass plate is further comprised.According to a particular embodiment of the invention, can be with the process
Flat glass plate is cut using Digit Control Machine Tool and using diamond cutter, to obtain the flat glass plate of preliminary dimension.
According to an embodiment of the invention, the first processing can be carried out at least a portion surface of flat glass plate, so as in plane glass
At least a portion surface of glass plate forms the first texture face.
Specifically, in this step, flat glass plate can be performed etching using etching liquid, i.e., soaked flat glass plate
Bubble is etched in etching solution.According to an embodiment of the invention, with reference to figure 2, wet etching may comprise steps of：
S10：In flat glass plate surface, mask is set
In this step, mask is set in flat glass plate surface.According to an embodiment of the invention, the specific of mask is set
Mode is not particularly limited, for example, photosensitive-ink printing can be carried out to flat glass plate, photosensitive-ink, which is used for covering, not to be needed
The flat glass plate region being etched.Specifically, according to an embodiment of the invention, can be first according to the texture or figure of design
Case makes corresponding film, is then solidified by film exposure imaging, to form the masking to corresponding texture or pattern.
S20：Flat glass plate is provided with into mask one is placed in etching liquid
In this step, flat glass plate is provided with into mask one is placed in etching liquid, is performed etching.According to this hair
Bright embodiment, the species of etching liquid and specific etching mode are not particularly limited, if can on flat glass plate shape
Into etching texture, for example, according to a particular embodiment of the invention, the flat glass plate that print masking ink can be soaked
Enter and be etched in the etching solution based on hydrofluoric acid.
S30：Remove mask
In this step, mask is removed, to form the first texture face after etching.According to an embodiment of the invention, may be used
To use specific alkalescent (concentration：1-5%) solution removes the ink of masking, thus, the flat glass of ink shaded areas
Plate is not etched by, and is penetrating luster effect, and the first texture face is formd through overetched flat glass plate region, is cloudy surface dumb light
Effect.Thus, the first texture face and flat glass plate region not etched constitutes in the first layer depth and visual texture
Pattern effect.According to a particular embodiment of the invention, the glossiness in the first texture face that the step is formed can be 25-65, slightly

The nitration mixture aqueous solution of acetic acid.Thus, it is possible to easily realize the etching to flat glass plate, and this is not significantly affected by after etching
The overall mechanical strength of flat glass plate.
S200：Form the second texture face
According to an embodiment of the invention, in this step, the setting figure on the flat glass plate in the first texture face is provided with
Pattern layer, to form the second texture face.According to a particular embodiment of the invention, it can be by ultraviolet stamping to set patterned layer
What at least one of reason, hot padding processing and 3D printing were realized.According to an embodiment of the invention, the second texture face and first
Texture face, flat glass plate projection in the plane, can also only be overlapped with completely overlapped, can be with complete
It is complete not overlapping.
Specifically, ultraviolet stamping processing is to utilize ultraviolet cured adhesive, promotes to imprint by the uv-exposure of transparent stamper
Polymerization and curing molding, and then the method for forming textured pattern occur for the ultraviolet cured adhesive in region.Hot padding processing is in height
Under warm high pressure, pressing mold is pressed on the thin polymer film on substrate, then temperature reduced, then pressing mold and polymeric layer phase point
From, and then the method for forming textured pattern.3D printing is based on mathematical model file, with powdery metal or plastics etc.
Can jointing material, can also form textured pattern by way of successively printing come the method for constructed object, the method.Thus,
The method for setting patterned layer can have multiple choices, and easy to operate.According to an embodiment of the invention, the tool of patterned layer is set
Body method and operating parameter are not particularly limited, as long as texture, people in the art can be formed in flat glass plate surface
