The color glass according to an embodiment of the present invention can be applied mainly to architectural windows, and when applied to a building, the color seen from the outside can be the same or almost the same as the color seen from the inside.

Hereinafter, a laminated structure of colored glass according to an embodiment of the present invention will be described in detail with reference to FIG.

1 is a cross-sectional view showing a colored glass according to an embodiment of the present invention.

1, a color glass 1 according to an embodiment of the present invention includes a glass layer 10 serving as a base, a mat layer 20 formed on one side of the glass layer, 1 color layer 30 and a reflective layer 40 so that the color seen by the first color layer when viewed through the matte layer can be more clearly perceived, A second color layer 50 representing color, and a protection layer 60 for preventing oxidation of the second color layer.

The glass layer 10 may be made of a plate-like transparent glass having a predetermined width. It is preferable that the thickness of the glass layer 10 has an appropriate thickness not to break when the mat layer 20 is formed on one surface.

The matte layer 20 may have irregular concave and convex surfaces on one surface (or the rear surface of the glass layer) of the glass layer 10 so as to increase irregular reflection so that the light has no directionality. Accordingly, the color glass 1 can eliminate the color difference due to the angular difference and can exhibit a color close to the original color.

The thickness t1 of the mat layer 20 may be 20 nm to 50 nm and the material is the same as the glass layer as one surface of the glass layer 10 is processed. The mat layer 20 can prevent a difference in light absorption from occurring. When the thickness of the mat layer 20 is less than 20 nm, the degree of increase of the hard reflectance becomes insignificant. When the thickness exceeds 50 nm, the light transmittance becomes low, and therefore, the effect of the mat layer 20 can not be obtained.

The first color layer 30 is laminated to the matte layer 20 to determine the color of the colored glass 1. The first color layer 30 has a predetermined light transmittance through which light can pass and has a high refractive index. The thickness t2 of the first color layer 30 may be 50 nm to 300 nm.

And may include a metal material of the first color layer 30, for example, an NbOX alloy including Ni or Cr. The first color layer 30 may have various colors depending on its thickness.

The reflective layer 40 may have a thickness that is formed on the first color layer 30 and reflects a part of the light and transmits the remaining light. In this case, the thickness t3 of the reflective layer 40 may be 20 nm to 40 nm and the light transmittance may be 8 to 20%. Also, the reflective layer 40 may be formed of a thin film containing any one of metal materials such as Al, Ag, Cu, Cr, and Au.

The reflective layer 40 reflects a part of light passing sequentially through the glass layer, the matte layer and the first color layer. Accordingly, the color glass 1 of the present embodiment can realize a clearer color than a conventional color glass without a reflective layer.

On the other hand, when the color glass 1 is placed on the outside of the building when the glass layer 10 is installed on the building, the color when the color glass 1 is viewed from the outside of the building, The second color layer 50 may be laminated on the reflective layer 40 so that the color when viewed from the first color layer 1 can be seen uniformly.

The second color layer 50 may be made of the same material as the first color layer 10 and may have a thickness t4 of 50 nm to 300 nm.

In this case, the first color layer 30 is visible through the glass layer 10 and the matte layer 20, and the second color layer 50 is visible through the protective layer 60. At this time, the first color layer 30 seen through the matte layer 20 appears brighter and sharper than the second color layer 50. Compensating the refractive index according to the difference in loss of light as described above, the first and second color layers 30 and 50 can be expressed in the same color. That is, the thickness t5 of the second color layer 50 is set to be greater than the thickness t2 of the first color layer 30, considering the loss of light compared to the first color layer 30, t3 can be formed to be thicker.

In addition, the method of forming the first and second color layers 30 and 50 in the same color is not limited to forming the thicknesses of the respective color layers differently as described above, The first and second color layers 30 and 50 may be implemented in the same color by changing the material of the second color layer to an alloy containing TiO 2 or Nb 2 O 5 that is different from the material of the first color layer have.

The protective layer 60 is located inside the building when the colored glass 1 is applied to the building. In this case, there is a problem that it is easily oxidized due to exposure to environment such as high temperature / high humidity of the room. Therefore, in order to prevent this, it is possible to laminate the second color layer 50 to improve the durability of the color glass 1. The protective layer 60 may have a thickness t5 of 20 nm to 50 nm and may include any one of Si, SiO2, SiOC, SiOCH, SiN, and SiON that can transmit light.

The color glass 1 according to the present embodiment has been described as having the first and second color layers 30 and 50 together. However, the second color layer 50 may be omitted in the case where the color does not need to match when the color glass is viewed from the inside and the outside of the building after the building is installed. In this case, the protective layer 60 may be laminated on the reflective layer 40 to prevent the reflective layer 40 from being oxidized by reaction with air.

Hereinafter, the manufacturing process of the color glass according to one embodiment of the present invention will be sequentially described with reference to FIGS. 2 to 6. FIG.

First, a glass plate having a predetermined width to form the glass layer 10 is prepared (S1).

Subsequently, a mat layer 20 is formed on one surface 11 (or the rear surface of the glass layer) of the glass layer 10 by a conventional sandblasting process as shown in FIG. 3 (S2). As the nozzle 70 moves, a predetermined particle sand 71 is sprayed onto one surface 11 of the glass layer to form a mat layer 20 having irregular uneven surfaces as shown in Fig. 4 on one surface of the glass layer. In this case, the thickness t1 of the mat layer 20 may be approximately 20 nm to 50 nm.

Subsequently, the first color layer 30 is formed on the mat layer 20 by a plasma process (S3).

Specifically, as shown in Fig. 5, the glass plate 1a formed up to the matte layer 20 is charged into the vacuum chamber 80. As shown in Fig. At this time, the glass plate 1a is fixed to the support 81 disposed in the vacuum chamber 80. [ In this state, the inside of the vacuum chamber 80 is formed in a vacuum atmosphere, various gases for the plasma process are supplied into the vacuum chamber 80, and a voltage is applied to form a plasma. At this time, as the metal ions of the target 83 are deposited on the matte layer 20 by sputtering, the first color layer 30 is laminated to a predetermined thickness on one side 21 of the matte layer.

6, the thickness of the first color layer 30 is about 203 nm, which is a value falling within the range of 50 nm to 300 nm, which is the thickness t2 of the first color layer 30.

Next, a reflective layer 40 may be laminated on the first color layer 30 (S4). The reflective layer 40 reflects the light incident from the front of the colored glass back to the front of the colored glass.

The reflective layer 40 may also be formed by a plasma process, in which case the target is formed as a target of a material different from that used to form the first color layer. Referring to FIG. 6, the thickness of the reflective layer 40 may be about 25.3 nm, which is a value in the range of 20 nm to 40 nm, which is the thickness t3 of the reflective layer 30.

Next, a second color layer 50 may be formed on the reflective layer 40 (S5).

The second color layer 50 may be formed through a plasma process as in the case of forming the first color layer and the reflective layer. In this case, the target uses the same material as that used for forming the first color layer. However, the thickness of the second color layer to be laminated is thicker than the thickness of the first color layer. 6, the thickness of the second color layer 50 may be about 233 nm, which is a value within the range of 50 nm to 300 nm, which is the thickness t3 of the second color layer 50.

Subsequently, a transparent protective layer 60 may be laminated on the second color layer 50 (S6). The protective layer 60 is formed by drawing the colored glass laminated from the vacuum chamber to the second color layer and then removing the Si-based protective layer 60 from the second color layer 50 through a normal spraying or applying process. .

In this case, it is preferable that the protective layer 60 is formed so as to cover the entirety of the second color layer 50 so that the second color layer 50 is not in contact with air. Referring to FIG. 6, the thickness of the protective layer 60 may be 33.8 nm, which is a value within the range of 20 nm to 50 nm, which is the thickness t5 of the protective layer 60.

It has been described that the second color layers 30 and 50 are formed in the manufacturing process of the color glass 1 according to the embodiment of the present invention described above. However, in the case where the colors do not need to match when the color glass is viewed from the inside and the outside of the building after the construction, the process of forming the second color layer 50 may be omitted, May be directly laminated on the reflective layer 40 to prevent the protective layer 60 from being oxidized by reaction with air.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
