Hereinafter, with reference to the embodiment shown in the drawings will be described in more detail the decorative glass having a double-sided pattern and its manufacturing method according to the present invention.

1 and 2 are a perspective view and a cross-sectional view of a deco glass having a double-sided pattern according to an embodiment of the present invention, Figure 3 is a flow chart illustrating a method of manufacturing a deco glass having a double-sided pattern in accordance with an embodiment of the present invention. to be.

1 and 2, the decorative glass having a double-sided pattern according to the present invention is the surface pattern layer 10, the glass plate 20, the back pattern layer 30, and the laminating layer 40 is sequentially stacked It is.

The surface pattern layer 10 is provided by melting a glass powder and an inorganic ink mixed with the inorganic pigment pigment on the surface of the glass plate 20 is fused.

That is, since the surface pattern layer 10 is exposed to the outside, abrasion resistance and scratch resistance will be required. The surface printing step S10, the first drying step S20, and the sintering step S30 will be described sequentially. When the superfine ink is fused to the surface of the glass plate 20, the surface pattern layer 10 may not only have abrasion resistance and scratch resistance, but the surface pattern layer 10 may be exaggerated slightly in FIG. 1. Protruding to the surface of the glass plate 20 will have a three-dimensional texture, it is possible to give an etching effect.

The back pattern layer 30 is provided by screen printing with a silk screen ink mixed with an acryl meramine-based compound or an inorganic compound on the rear surface of the glass plate 20.

That is, the back pattern layer 20 is screen-printed on the back surface of the glass plate 20 through the back printing step (S40) and the second drying step (S50) to be described later, the back pattern layer 30 The distance between the surface pattern layer 10 and the glass plate 20 is provided with a distance so as to be able to create a three-dimensional aesthetic in the decor glass according to an embodiment of the present invention with the surface pattern layer 10 as a whole Will be.

The laminating layer 40 is provided with a laminating process under the rear pattern layer 30.

That is, the laminating layer 40 may laminate the lower portion of the rear pattern layer 30 to make the rear pattern layer 30 relatively weaker to moisture than the surface pattern layer 10 in which the vitreous ink is fused. By protecting from moisture, the rear pattern layer 30 serves to have moisture resistance. Of course, the back pattern layer 30 also serves to prevent scratches from occurring.

In the above, the decorative glass having a double-sided pattern according to an embodiment of the present invention has been described. Hereinafter, the manufacturing method of the decorative glass having a double-sided pattern according to an embodiment of the present invention will be described.

Referring to Figure 3, the manufacturing method of the decorative glass having a double-sided pattern according to an embodiment of the present invention, the surface printing step (S10), the first drying step (S20), the firing step (S30) and the back It comprises a printing step (S40), a second drying step (S50), and a laminating step (S60).

The surface printing step (S10) is a step of screen printing the surface of the glass plate 20 with a superfine ink mixed with a glass powder and an inorganic coloring pigment.

The vitreous ink preferably comprises 45% by weight to 55% by weight of glass powder, 25% by weight to 35% by weight of inorganic pigmented pigment, and 15% by weight to 25% by weight of oil.

The first drying step (S20) is a step of drying the glass plate 20 for 4 to 6 minutes with an infrared lamp that emits heat of 140 ℃ to 160 ℃ to dry the candle ink.

That is, the vitreous ink is firmly attached to the surface of the glass plate 20 by drying. The first drying step S20 has a meaning as a previous step of the relatively high temperature litigation step S30 which will be described later. Compared to the second drying step (S50) to be described later with an infrared lamp that emits heat of 140 ℃ to 160 ℃ (20) may be dried for a relatively short time 4 minutes to 6 minutes.

On the other hand, by using an infrared lamp as a heat source of heat to emit a temperature of 140 ℃ to 160 ℃, that is, by using an infrared drying method can solve the problem that foreign matter is blown by the wind of the hot air drying method commonly used, The temperature can be kept constant, even if the laminated glass plate is dried, there is an effect that can be uniform drying.

2 degrees or 3 by the method of going through the surface printing step (S10) and the first drying step (S20) once again to form another surface pattern layer on the glass plate 20 that passed through the first drying step (S20). It is a matter of course that the surface pattern layer of FIG.

The firing step (S30) is a step for fusion of the vitreous ink on the surface of the glass plate 20, the glass plate 20 in a firing furnace having an internal temperature of 650 ℃ to 700 ℃ 1 minute 30 seconds to 2 minutes This step is for 30 seconds.

When the baking step (S30) is passed through the glass plate 20 and the vitreous ink is partially fused and mutually fused to form a semi-permanent surface pattern layer 10 on the surface of the glass plate 20, the firing step ( The surface pattern layer 10 may not only have abrasion resistance and scratch resistance, but is slightly exaggerated in FIG. 1 but the surface pattern layer 10 may be formed of the glass plate 20. It protrudes to the surface to have a three-dimensional texture, and furthermore it is possible to give an etching effect.

On the other hand, the first drying step (S20) and the firing step (S30) is arranged so that the tunnel-type first drying furnace and the tunnel-type firing furnace having a predetermined length so as to be carried out continuously to the conveyor to move the glass plate 20 on the conveyor. It is desirable to.

The back printing step (S40) is a step of screen printing the back surface of the glass plate 20 with a silk screen ink mixed with an acrylic melamine-based compound or an inorganic compound.

That is, when the glass plate 20 undergoes the firing step (S30) is naturally cooled while being moved to the back printing step (S40), the silk screen to form the back pattern layer 30 on the back surface of the glass plate 20 Screen printing with ink.

In particular, when the ink mixed with an inorganic compound is used as the ink for the silk screen, unlike the binding structure by the one-step reaction of the ink in which the acryl melamine-based compound is mixed, the bonding structure by the two-step reaction is formed, and the inorganic By attaching the compound to the glass plate 20, which is an inorganic material, by chemical bonding, screen printing is more robust and excellent in moisture resistance.

On the other hand, the back printing step (S40) and the subsequent steps (S50, S60) in the present invention is the step for forming the surface pattern layer 10 on the surface of the glass plate 20 (S10, S20, S30), but if the back printing step (S40) is made before the firing step (S30), the back pattern layer 30 by the temperature of 650 ℃ to 700 ℃ in the firing step (S30) This is because the melted pattern is destroyed.

The second drying step (S50) is a step of drying the glass plate 20 for 6 to 8 minutes with an infrared lamp emitting heat of 140 ℃ to 160 ℃ to dry the silk screen ink.

That is, the second drying step (S50) is similar to the first drying step (S20), while the silk-screen ink screen-printed on the back of the glass plate 20 is dried firmly on the back of the glass plate 20 This step is to be attached.

Meanwhile, since there is no step corresponding to the firing step (S30) after the first drying step (S20) after the second drying step (S50), 4 minutes to 6 minutes of the first drying step (S20). A relatively long drying time of 6 to 8 minutes is required rather than a drying time of minutes.

The second printing step (S40) and the second drying step (S50) to go through the second printing step (S50) once again to form another back pattern layer on the glass plate 20 through the second drying step (S50) of 2 degrees or 3 degrees It is a matter of course that the back pattern layer may be formed.

The laminating step S60 is a step of laminating a lower portion of the back pattern layer 30.

That is, in the laminating step S60, the lower portion of the rear pattern layer 30 is laminated so that the rear pattern layer 30 that is relatively weaker to moisture than the surface pattern layer 10 in which the vitreous ink is fused is damp. It is protected from the back pattern layer 30 to have moisture resistance. Of course, the back pattern layer 30 also serves to prevent scratches from occurring.
