DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stained glass design glass and a method for producing the same.

[0002]

2. Description of the Related Art An original stained glass is composed of colored glass arranged in a mosaic shape, its contacts are connected with lead, and a combination of colors of the colored glass forms a picture or other pattern. Due to the high level, there are many requests for adoption.However, the coloring process and arrangement process of glass, joining technology using lead, etc. are very difficult, requiring skill, and the work environment and hygiene associated with using lead. Due to the problem, no skill is required, it can be easily and inexpensively manufactured, and
Various pseudo stained glasses that do not cause environmental problems have been proposed.

[0003] Such pseudo-stained glass includes the first
As a group, a method of bonding a film having a pattern or the like printed on a sheet glass (Japanese Patent Publication No. 62-20039) and a method of directly printing or painting a pattern or the like on a sheet glass (Japanese Patent Application Laid-Open No. 58-1983).
-79345 and Japanese Utility Model Laid-Open No. 4-71299). In addition, as a second group, a method in which a plurality of colored glass pieces are juxtaposed and adhered to one surface of a plate glass at an interval from each other, and a joint material such as mortar is filled between the colored glass pieces (registered utility model No. 3022912). There is.

[0004]

However, the first group is good in color because the pattern and the like are expressed in a plane as a whole. There is a shortcoming with a poor feeling. In the case of the second group, if a colored glass piece is made of template glass, a three-dimensional appearance is obtained, but the filling portion filled in the gap between the glass pieces is flush with the glass surface or slightly recessed. As a result, there is no three-dimensional effect as in the case of the lead wire portion protruding from the glass surface of the true stained glass. Further, since the back surface opposite to the glass piece is only a flat surface of the glass sheet, its appearance does not resemble a true stained glass at all. In addition, in the second group, a colored glass piece is adhered to a plate glass. However, when this is incorporated in a sash, the thickness of the glass plate is limited, so the plate glass serving as the substrate must be thinned.
Therefore, the impact resistance of the pseudo stained glass is inferior, and when the glass plate is damaged, there is a risk that the glass pieces may be scattered.

[0005] The present invention has been made in view of the above circumstances, and an object of the first invention is easy to manufacture, has the same three-dimensional appearance as a true stained glass, and has excellent impact resistance.
An object of the present invention is to provide a stained glass-like design glass which is less likely to be scattered when a glass plate is broken and has excellent heat insulating properties. Another object of the present invention is to provide a method for simply and efficiently producing a design glass having an appearance similar to a true stained glass without requiring skill such as lead bonding technology.

[0006]

In order to achieve the first object, a stained glass-like design glass according to the present invention is provided on one surface of a transparent plate glass with a pattern line corresponding to a boundary line of each color glass piece of a true stained glass. Are printed so as to protrude, a plurality of glass pieces are adhered along the pattern line to the other surface of the plate glass via an adhesive translucent film, and are filled in gaps between the glass pieces. In addition, joints protruding from the gap to the outer surface of the glass piece are formed. According to the above configuration, the design glass has pattern lines and joints protruding on both front and back surfaces, and has an appearance very similar to a true stained glass and has a three-dimensional appearance.

[0007] It is desirable that the transparent plate glass and the glass piece are adhered by heat-melting the adhesive translucent film interposed therebetween. Thereby, it is excellent in impact resistance, and even if the glass plate is broken, scattering is effectively prevented.

[0008] Between the two adhesive translucent films, a decorative translucent film on which a pattern, design, or other pattern is printed or handwritten with translucent colored ink may be interposed. desirable. Thereby, even if a colorless and translucent glass piece is used, a design glass having a pattern similar to a true stained glass can be provided.

It is preferable that the translucent film for adhesion contains an ultraviolet absorber. Thereby, when this design glass is used for a window glass, ultraviolet rays from outdoors to indoors are effectively blocked.

The method for producing a stained glass-like design glass according to the present invention comprises a first step of printing a pattern line on one surface of a transparent plate glass so as to protrude, and a translucent film for bonding on the other surface of the plate glass. A second step of placing,
A third step of arranging a plurality of glass pieces along the pattern lines on the upper surface of the light-transmitting film for bonding and temporarily fixing the glass pieces, and heating the glass sheet after the third step at a predetermined temperature in a vacuum furnace. Melting the translucent film for bonding, and pressing the plate glass, the translucent film and the glass piece under pressure, filling a gap between the glass pieces with a joint material by printing, and raising the gap. It consists of a fifth step.
By combining the above processes, it is possible to efficiently mass-produce design glass whose appearance is very similar to genuine stained glass, has excellent discoloration resistance and impact resistance, and prevents scattering of glass when broken. it can.

Further, in the method of the present invention, the pattern lines in the first step are printed by screen printing using an epoxy resin-based ink, and the ink is cured by heating at 150 ° C. for about 60 minutes. Thermocompression bonding is the third
The intermediate product after the process is put into a furnace, the degree of vacuum in the furnace is increased, and heating is performed at about 100 ° C. for about 30 minutes. The joint in the fifth step is filled with joint material by screen printing. It is characterized by being formed and cured by heating at about 80 ° C. for about 30 minutes.
Thereby, the production efficiency can be further improved.

[0012]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a mere example of a pattern of a design glass according to the present invention, and FIG. 2 is a cross-sectional view along a line XX of FIG. 1 with a part thereof omitted.

In FIG. 2, reference numeral 1 denotes a transparent plate glass. Haze glass, plain glass, polished glass and the like having a thickness of about 2 to 6.8 mm can be used. When the design glass according to the present invention requires security, earthquake resistance, and the like, a sheet glass with a net is used. In particular, when high soundproofing is required or when the area is large, a thick plate glass of about 6, 8, 10 mm is used.

In FIG. 2, reference numeral 2 denotes a pattern line provided so as to protrude on one side of the glass sheet 1 and is filled between the edges of each colored glass piece of genuine stained glass to form a lead wire for joining the colored glass. It is equivalent. The pattern line 2 is formed by printing an epoxy resin-based ink by screen printing along a pattern of a design glass, which is a final product, and heating and curing at 150 ° C. for about 60 minutes. By using a thick screen, the printed ink is raised from the glass surface.

On the other surface of the plate glass 1, that is, on the surface opposite to the surface on which the pattern lines 2 are provided, a translucent film 3 for adhesion is placed. On the upper surface of the film, a plurality of glass pieces 5 having substantially the same planar shape as the shape of the surface surrounded by the pattern lines are arranged along the pattern lines. That is, the glass pieces are arranged such that the gap formed between the glass pieces is continuous along the pattern line. In the glass piece 5,
Colored or colorless etched glass or template glass, printed glass, ground glass, or the like can be used. In particular, when a combination of one or more types of template glass, such as mist, mist, and wood, is used, a required three-dimensional effect can be obtained in the finished product.

In a preferred embodiment, as in the example shown,
A translucent film 4 for decoration, such as a ground glass-like or Japanese paper-like processed polyester film, is interposed between the translucent films 3 for bonding. When this film is interposed, a desired pattern can be easily provided on the finished product by printing a desired pattern on the film, even if a colorless glass piece 5 is used. In addition, since the melted film 3 is interposed between the glasses 1 and 5 on both sides, when the plate glass 1 or the glass piece 5 is damaged due to a large earthquake or an impact due to a flying object, the scattering is prevented. It can be effectively prevented. Further, by using a film having a small heat conduction coefficient and / or a small sound conduction coefficient for the films 3 and / or 4, it is possible to obtain a design glass having high heat insulation / sound insulation.

However, the glass piece 5 may be bonded directly to the other surface of the plate glass 1 without interposing the decorative translucent film 4. In this case, it is desirable to use a colored mold plate glass for the glass piece 5. As a result, the same color and three-dimensional effect as the true stained glass can be obtained.

In FIGS. 1 and 2, reference numeral 6 denotes a joint portion which is filled in a gap formed between the glass pieces and protrudes from the gap to the outer surface of the glass piece. The joint portion 6 is formed by screen printing using an epoxy resin-based adhesive as a filling material. Since the joints are raised from the glass surface and have an appearance similar to that of a true stained glass lead wire, the entire design glass has an appearance similar to a true stained glass.

As described above, the pattern line 2 and the joint 6
Has the same pattern and is formed by screen printing, so that skill such as in the case of the lead wire coupling technique when manufacturing a true test glass is not required, and the glass piece 5 is printed first. Since it is only necessary to stick along the pattern line that has been made, even an amateur can easily perform accurate placement and adhesion of glass pieces, which is suitable for mass production. And
By changing the printing screen, it is possible to easily produce a design glass having another pattern.

Next, an embodiment of the design glass manufacturing method according to the present invention will be described in detail for each step with reference to FIG. First, as a first step (a),
One side of the plate glass 1 as a substrate is printed by a screen printing machine having a screen melt-processed according to a predetermined pattern, heated at 150 ° C. for about 60 minutes to make the ink coin, and the pattern lines protruding from the plate glass surface. 2
To form For normal screen printing, plate thickness 80μ
In this method, a thick screen having a plate thickness of 300 μm is used in order to raise the printed pattern lines. As an example of the printing ink, an epoxy resin-based ink such as Epoxy 1690 (trade name) can be used. When such an ink is used, a pattern line 2 protruding to a thickness of about 0.3 mm can be printed on the surface of the sheet glass 1.

Next, as a second step (b), in one embodiment, the plate glass 1 on which the pattern lines 2 are printed is washed using a known washing machine, and the other surface of the plate glass (the pattern lines are printed). The translucent film 3 for adhesion such as a modified polyolefin-based adhesive resin film is placed on the surface opposite to the surface that has been subjected to the treatment. The washing is performed in order to ensure the adhesion between the film 3 and the sheet glass at the time of the thermocompression bonding in the fourth step. As another embodiment of the second step (b), instead of mounting only the light transmitting film 3 for bonding, the light transmitting film 3 for decoration, the light transmitting film 4 for decoration, and the light transmitting film for bonding are used. In some cases, a three-layer structure in which the conductive film 3 is laminated is placed.

Subsequently, as a third step (c), a glass piece 5 is placed on the upper surface of the adhesive light-transmitting film 3 or the three-layer structure placed on the sheet glass 1 with the previously printed pattern line 2.
And temporarily fixed at intervals with a short adhesive tape 7. In this case, a slight gap is formed between each piece of glass. Preferably, after fixing the glass piece, it is washed by the washing machine. The purpose of the cleaning in this case is the same as the above-mentioned cleaning.

In a fourth step (d), the intermediate product after the third step is placed in a furnace, the furnace is evacuated, and heated at 100 ° C. for about 30 minutes.
The adhesive film 3 is melted, and the plate glass 1, the film 3 and the glass piece 5 are pressed. By applying a vacuum, air existing between the film 3 and the glasses 1 and 5 is completely removed, and separation between the bonding film 3 and the glasses 1 and 5 is effectively prevented. Thereby, in the intermediate product taken out of the furnace after the heating, the sheet glass 1, the film 3 and the glass piece 5 are completely and firmly joined, and a strong adhesive force is obtained therebetween, so that high impact resistance is obtained. Further, the material of the film 3 or 3 and 4 has heat and sound insulation performance.

As a final step (e), the temporary fixing adhesive tape 7 is removed, and the screen printing machine
As an example, using an epoxy resin adhesive having a composition such as Bond E250 (trade name) as a joint material, printing is performed on the surface of each glass piece 5 of the intermediate product taken out of the furnace, and the joint material is made of glass. The gap between the pieces is filled, and the surplus material overflows from the gap to form joints 6 protruding from the glass surface.
The composition is cured by heating at about C for about 30 minutes. By using the same screen as that used for printing the pattern lines 2 and appropriately setting the supply amount of the epoxy resin-based adhesive, joints protruding from the glass surface can be easily formed. In the case where the glass piece is a template glass, unevenness is generated depending on the height of the adjacent glass piece, so that a spacer having a thickness of 300 μm or more is provided with a glass having a thickness of 300 μm or more in order to surely hide the unevenness by joints. It is preferable to arrange on both sides of the gap between each other, fill the filling material between them, surely raise the joint, and then remove the spacer and perform baking. Also, after printing the pattern line, about 60 at 150 °
Heating for 30 minutes and applying heat and pressure with the translucent film 3 for bonding are performed at 100 ° C. for about 30 minutes. Therefore, when joints are formed, the bonding is performed at a lower temperature of 80 ° C. for about 30 minutes. .

According to the above embodiment, the above five steps make it possible to easily arrange and join glass pieces in a desired pattern at a speed per hour, and have the same appearance as a true stained glass sectioned by a lead wire. Thus, it is possible to efficiently produce a design glass having a three-dimensional appearance.

[0026]

As described above, according to the first aspect of the present invention, a protruding pattern line is printed on one surface of the translucent plate glass, and a plurality of glass pieces are formed on the other surface of the plate glass. The joints filled along the gaps between the glass pieces are formed so as to protrude on the outer surface of the glass pieces, so the appearance is very similar to a true stained glass, a three-dimensional design Glass can be provided.

According to the second aspect of the present invention, since the bonding translucent film is interposed between the transparent plate glass and the glass piece, it is excellent in impact resistance and can be used when the glass plate is broken. Also, scattering is effectively prevented. Further, by selecting the material of the film, it is possible to easily obtain a design glass having excellent heat insulating properties and soundproofing properties.

According to the third aspect of the present invention, when a pattern, a pattern, or another pattern is printed or hand-written on the translucent decorative film with the translucent colored ink, the colorless translucent film is printed. Even if glass pieces are used, it is possible to provide a design glass having a pattern similar to a true stained glass.

According to the fourth aspect of the present invention, when the translucent film for adhesion contains an ultraviolet absorber, when the design glass is used for a window glass, ultraviolet rays from the outdoors to the indoors are effectively blocked. Is done.

Further, according to the method of the present invention, a design glass having an appearance very similar to a true stained glass, having excellent discoloration resistance and impact resistance, and preventing the glass from being scattered in the case of breakage can be efficiently produced. Can be mass-produced.

According to the method described in claim 7, the production efficiency can be further improved.
