Method for manufacturing stained glass based on non-reflecting glass and stained glass by the manufacturing method

The present invention relates to stained glass, and more particularly, to a method of manufacturing stained glass based on non-reflecting glass, which is manufactured based on non-reflecting glass, and which can increase sharpness and concentration by minimizing disturbance elements of an image due to reflected light. And it relates to the stained glass by the manufacturing method.

There are various types of glass, and for example, it is widely used in all areas of life, from interior and exterior of buildings to electronic products, kitchenware, fashion industry, science and art fields, and industrial fields. Among these glasses, the plate glass has a predetermined thickness and is cut to a required size and shape, and then mounted on, for example, a window of a building or vehicle, and serves to distinguish indoors and outdoors.

The flat glass includes, in addition to simple general low-cost flat glass, those having special purposes such as tempered glass, low-E glass, and anti-reflective glass. Low-E glass is coated with a metal or metal oxide on the surface and can effectively block infrared rays. In addition , anti-reflection glass is a glass that reduces the reflection of light, and is manufactured by rough grinding the surface and then rounding the acute-angle part, or forming fine irregularities on the surface by spraying.

Such plate glass is also used as a base material for stained glass. As is known, stained glass is a decorative glass plate produced by connecting colored glass pieces with lead came (hereinafter, referred to as 'red came'), and is mainly installed on the walls of large churches or churches.

The traditional manufacturing method of stained glass involves the process of connecting colored panes of glass one by one using red cam. However, this manufacturing method has the disadvantage that the work process itself is complicated and the manufacturing cost is high. For this reason, stained glass having a structure that is easier to manufacture has been developed.

For example, in Korean Patent Application Laid-Open No. 10-2020-0003637, an integrated stained glass has been disclosed. The disclosed stained glass includes a base glass that forms a rear portion while reinforcing strength, a coupling member mounted on one surface (upper surface) of the base glass and having elasticity, and a plurality of colored glasses mounted on the coupling member and sandwiched respectively It is composed of a frame member for colored glass having a plurality of kiwoom holes so as to be lowered, and a plurality of colored glasses that are respectively fitted into the fitting holes of the frame member for colored glass.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is a flowchart for explaining a method of manufacturing stained glass based on non-reflecting glass according to an embodiment of the present invention, and FIGS. 2A to 2I are diagrams schematically illustrating the method of manufacturing stained glass.

As shown, the stained glass manufacturing method according to the present embodiment includes a non-reflecting glass plate preparation step 101, a groove processing step 103, a surface treatment step 105, a coloring step 107, and a kiln firing step 109. , a groove filling step 111 , a drying step 113 , a lamination and sealing step 115 , and a packaging step 117 .

The non-reflective glass plate preparation step 101 is a process of preparing the non-reflective glass plate 11 used as a base material for stained glass. The non-reflecting glass plate 11 is a glass plate having a rectangular or curved shape having a certain thickness, and the size varies according to need.

The groove processing step 103 is a process of forming a boundary groove 11a on one side of the anti-reflective glass 11 . The boundary groove 11a is, so to speak, a seat for expressing the red came of the antique stained glass, and accommodates the filler 19, as will be described later. The filler 19 mimics a cam, that is, a lead wire. Although the filler is not lead, it gives the impression of lead wire.

When the stained glass according to the present embodiment is viewed from a distance, the filler 19 creates a feeling like a cam, creating a more classic and serious atmosphere. Naturally, the shape or shape of the boundary groove 11a is not standardized, but varies depending on the picture or design to be expressed.

The depth of the boundary groove 11a or the shape of the bottom surface may vary depending on the groove processing method. In the present embodiment, the groove processing step 103 may be performed by any one of a stamping process 103a, a chemical etching process 103b, or a sanding process 103c.

The groove processing step 103 may be performed after the surface treatment step 105 to be described later.

3A to 3D are diagrams for explaining the stamping process 103a.

The stamping process 103a is a method of forming the boundary groove 11a by pressing the non-reflecting glass plate 11 in a heated state. In order to perform the stamping process 103a, first, the anti-reflective glass plate 11 is put into the heating device and heated. The heating temperature varies depending on the composition of the internal structure of the anti-reflection glass plate.

If the non-reflecting glass plate 11 has reached the deformation temperature through this heating process, the heated non-reflective glass plate 11 is placed on the forming plate 64 and pressed with a flat plate press 65 to form the boundary groove 11a. The molding plate 64 is a fixed mold provided with projections 64a for forming the boundary grooves 11a, and supports the non-reflective glass plate 11 horizontally.

When the flat press 65 is lowered to press the anti-reflective glass plate 11 downward, the non-reflective glass plate 11 is compressed to form a boundary groove 11a and a colored surface 11c. The boundary groove 11a is a groove formed by the projection 64a, and the colored surface 11c is a flat portion to be colored by the pigment for glass.

After the above process is completed, the flat plate press 65 is raised and then the anti-reflective glass plate is slowly cooled to finish the stamping process.

4A to 4D are views sequentially illustrating the chemical etching process of FIG. 1 . The chemical etching process 103b utilizes the property of glass being corroded by hydrogen fluoride.

In order to perform the chemical etching process (103b), first, a resist sheet 67 is attached to the surface of the anti-reflective glass plate 11 . The resist sheet 67 is a sheet having a stable property to hydrogen fluoride. An etching passage 67a is formed in the resist sheet 67 attached to the upper surface of the anti-reflection glass plate 11 . The etching passage 67a is a hole through which the portion to be etched is exposed. In FIG. 4, the etching passage 67a is simply expressed as a straight line as an example of the etching passage 67a for convenience, but the etching passage 67a is to express a red cam in stained glass, and thus takes the form of a picture or design desired by the manufacturer.

A resist sheet 67 is also attached to the bottom surface of the anti-reflection glass plate 11 . The resist sheet 67 attached to the other side covers the entire other side of the non-reflecting glass plate 11 .

As described above, if the resist sheet 67 is attached, as shown in FIG. 4B , the anti-reflection glass is immersed in the etching solution 68a to corrode the exposed portion. Of course, the depth of the boundary groove 11a is controlled by adjusting the etching time and the concentration of the etching solution. When the boundary groove 11a of the desired depth is obtained, the anti-reflection glass is taken out, the resist sheet 67 is removed and washed to obtain an anti-reflective glass plate (11 in FIG. 4D) having the boundary groove 11a and the colored surface 11c. .

5A to 5C are diagrams for explaining the sanding process 103c in the groove processing step of FIG. 1 .

In order to proceed with the sanding process 103c, first, a protective tile 71 is disposed on the upper surface of the anti-reflective glass plate 11, but a portion to be sanded is exposed between the protective tiles 71. The part to be sanded is a part to form the boundary groove 11a. The protective tile 71 serves to protect the anti-reflective glass plate 11 during sanding.

When the setting of the protective tile 71 is completed, as shown in FIG. 5B , sanding is performed using the sanding device 51 . Through the sanding process, the portion exposed between the protective tiles is sanded to form the boundary groove 11a. The depth of the boundary groove (11a) is adjustable through the control of the sanding device (51). In particular, the bottom surface of the boundary groove 11a has a certain level of roughness due to the nature of sanding. When it has roughness, the bonding force with the filler 19 increases.

If the groove processing step 103 is completed through the above-described various processes, the surface treatment step 105 is performed. The surface treatment step 105 is a process of rough processing the entire surface of the non-reflecting glass plate 11 on which the boundary grooves 11a and the colored surface 11c are formed.

In this embodiment, the sanding device 51 is used for the surface treatment step 105 . The sanding device 51 used may be a sanding device used in the above-described sanding process 103c. Anyway, through the surface treatment step 105, the entire surface of the non-reflecting glass plate 11 is in a rough state, as shown in FIG. 2C.

The surface treatment step 105 is followed by a coloring step 107 . The coloring step 107 is a process of expressing a picture or design of a desired content on the colored surface 11c using a pigment for glass. Through the coloring step 107, the colored layer 13 is formed on the colored surface 11c of the anti-reflective glass plate 11, as shown in FIG. 2D.

In this coloring step 107, hand painting as well as various modern techniques can be applied. In other words, ceramic printing, silk screen, or a coloring method using spray can be applied.

When the coloring step 107 is completed, the kiln firing step 109 is performed. The kiln firing step 109 is a process of heating the colored non-reflective glass plate 11 into a heating kiln 53 . The heating temperature is 600° C. to 700° C., and the heating time varies depending on the thickness of the colored layer 13 , but may be about 20 to 50 minutes. The pigment constituting the colored layer 13 is integrated on the surface of the non-reflecting glass plate 11 through the kiln firing step 109 .

The subsequent groove filling step 111 is a process of filling the opaque filler 19 in the boundary groove 11a. The opaque filler 19 is a mixture of a pigment for opaque glass, an adhesive, glass powder, and charcoal powder.

The opaque pigment is a black-based pigment, and the opaque filler 19 is displayed blacker. The glass powder is a pulverized non-reflective glass plate of the same material as the non-reflective glass plate 11, and the particle size is 50 mesh to 100 mesh. Since the glass powder of the same material is mixed in this way, bonding of the inner bottom surface of the boundary groove 11a and the filler 19 is made more efficiently.

In addition, the charcoal powder makes the opaque filler 19 appear darker together with the opaque pigment.

In addition, a transparent epoxy-based adhesive may be used to bond the pigment, glass powder, and charcoal powder to each other, and at the same time serve to fix the opaque filler 19 to the inside of the boundary groove 11a.

This opaque filler 19 has a constant viscosity and is filled in the boundary groove 11a through the filler feeder 55 . As shown in FIG. 5F , the filler feeder 55 is a screw-feeding press-fitting device, and includes a hose 55a and a nozzle 55b. After passing through the hose 55a, the opaque filler 19 is extruded through the nozzle 55b and accommodated in the boundary groove 11a.

In particular, the opaque filler 19 rises higher than the color layer 13 . That is, the upper end of the opaque filler 19 protrudes upward by the height H more than the color layer 13 . The reason why the opaque filler 19 is protruded is to give a three-dimensional effect and to look as similar as possible to the cam.

If the groove filling step 111 is completed, the drying step 113 is performed. The drying step 113 is a process of drying the non-reflective glass plate 11 on which the injection of the opaque filler 19 has been completed, after placing it in the dryer 57 . The drying method may be hot air drying or cold air drying, and if necessary, a natural drying method may be applied.

In the lamination and sealing step 115, a rear glass plate 23b is placed on the rear surface of the non-reflective glass plate after the drying step 113 is completed, and a spacer 23c and a front glass plate 23a are laminated on the front surface, It is a process of forming the laminated glass plate 23 by sealing the space between the glass plates.

The front glass plate 23a and the rear glass plate 23b protect the internal non-reflective glass plate 11, and the type may be tempered glass, low-e glass, or non-reflective glass. The spacer 23c provides a space 23d between the front glass plate 23a and the anti-reflective glass plate 11 to prevent the opaque filler 19 from being pressed. The spacer 23c is also a glass plate of a certain thickness. An inert gas, such as argon gas, can also be enclosed in the space part 23d as needed.

The bonding of the rear glass plate 23b and the spacer 23c to the anti-reflection glass plate 11 and the bonding of the front glass plate 23a and the spacer 23c to the anti-reflective glass plate 11 are implemented with an adhesive for glass. The adhesive for glass serves to seal the space between the glass plates inside the laminated glass plate 23 .

The packaging step 117 is a process of filling the elastic frame 31 on the edge of the laminated glass plate 23 . The elastic frame 31 is a rectangular frame having an approximately U-shaped cross-sectional shape, and accommodates and protects the laminated glass plate 23 and prevents the laminated glass plate 23 from being opened.

6 is a partially cutaway perspective view of the stained glass 30 manufactured by the method for manufacturing the stained glass according to an embodiment of the present invention.

Referring to the drawings, it can be seen that the two stained glasses 30 are arranged vertically. The stained glass 30 is connected to each other and constitutes one work as a whole. Of course, the elastic frame 31 of the upper and lower stained glass 30 is in contact with each other.

In addition, it can be seen that the rear glass plate 23b, the non-reflecting glass plate 11, the spacer 23c, and the front glass plate 23a are filled in the elastic frame 31 in a stacked state, as shown in an enlarged view in the drawing. In addition, the colored layer 13 of the stained glass 30 is clearly separated by the opaque filler 19 . The opaque filler 19 is playing the role of a cam of the antique stained glass.

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those skilled in the art within the scope of the technical spirit of the present invention.
