The utility model discloses a colored glass that an embodiment relates to mainly can be applied to door and window for building, when being used for the building, can make the colour of looking colored glass from the outside or the colour of looking colored glass from the inside the same or almost the same.

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.

Referring to fig. 1, a colored glass (1) according to an embodiment of the present invention may include a primed glass layer (10), a cushion layer (20) formed on a surface of the glass layer, a first color layer (30) displaying a predetermined color, a reflective layer (40) which is more vivid in color when the colored glass (1) is viewed through the cushion layer, a second color layer (50) representing the same color as the first color layer, and a protective layer (60) preventing the second color layer from being oxidized.

The glass layer (10) may be formed of a plate-shaped transparent glass having a predetermined width. The thickness of the glass layer (10) is preferably a suitable thickness that does not damage the cushion layer (20) when formed on one surface.

The cushion layer (20) may be formed to have irregular convexes and concaves on one surface of the glass layer (10) (or the back surface of the glass layer) to increase diffuse reflection and make light non-directional. Therefore, the colored glass (1) can avoid the color difference caused by the angle difference and can show the color close to the inherent color.

The thickness (t1) of the pad layer (20) may be 20nm to 50nm, and the pad layer is formed by processing one surface of the glass layer (10) and is made of the same material as the glass layer. The underlayer (20) can prevent the difference caused by light absorption. When the thickness of the underlayer 20 is less than 20nm, the degree of increase in diffuse reflectance is very small, and when it exceeds 50nm, the light transmittance is lowered, and therefore the effect of the underlayer 20 cannot be achieved reliably.

The first color layer (30) is stacked on the pad layer (20) and determines the color of the colored glass (1). The first color layer (30) has a predetermined light transmittance through which light can be transmitted, and also has a high refractive index. The first color layer (30) may be formed to a thickness (t2) of 50nm to 300 nm.

The first color layer (30) may comprise a metallic material, such as an NbOX alloy comprising Ni or Cr. Such a first color layer (30) can realize various colors according to different thicknesses.

A reflective layer (40) is stacked on the first color layer (30) and is formed to have a thickness that reflects a part of light and transmits the rest of light. In this case, the reflective layer (40) is formed to have a thickness (t3) of 20 to 40nm and a light transmittance of 8 to 20%. The reflective layer (40) may be formed of a thin film made of any metal material such as aluminum, silver, copper, chromium, or gold.

The reflective layer (40) reflects a portion of light that passes through the glass layer, the cushion layer, and the first color layer in this order. Therefore, compared with the conventional colored glass without a reflecting layer, the colored glass (1) of the embodiment can realize more vivid color.

On the other hand, when the colored glass (1) is constructed on a building, a second color layer (50) can be stacked on the reflective layer (40) so that when the glass layer (10) is disposed outside the building, the color when the colored glass (1) is viewed from the outside of the building and the color when the colored glass (1) is viewed from the inside of the building look the same.

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

In this case, the first color layer (30) is visible through the glass layer (10) and the cushion 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 cushion layer (20) is brighter and clearer than the second color layer (50). Thus, the refractive index caused by the difference in loss of light can be compensated, and the first and second color layers (30, 50) can exhibit the same color. That is, the second color layer (50) may be formed to have a thickness (t5) thicker than that (t3) of the first color layer (30) in consideration of a greater light loss of the second color layer (50) with respect to the first color layer (30).

Furthermore, as the first and second color layers (30, 50) are realized to be the same colorThe method of (1) is not limited to the above, but the material of the second color layer can be changed to TiO containing layer with different material from the first color layer when the second color layer is formed on the reflective layer (40) by evaporation₂Or Nb₂O₅So that the first and second color layers (30, 50) can also achieve the same color.

When the colored glass (1) is constructed in a building, the protective layer (60) is positioned inside the building. At this time, since oxidation is liable to occur due to exposure to an environment of high temperature/humidity in a room, etc., in order to prevent this, a colored glass (1) can be stacked on the second color layer (50) to improve durability. The protective layer (60) may be formed to a thickness (t5) of 20nm to 50nm and may contain a light transmissive silicon species, i.e., SiO₂Any one of SiOC, SiOCH, SiN and SiON.

The colored glass (1) according to the present embodiment is described as having both the first and second color layers (30, 50). However, when the colored glass is viewed from the inside and outside of the building during the construction of the building, the second color layer (50) may be omitted if the colors do not need to be the same. In this case, a protective layer (60) may be further stacked on the reflective layer (40) to prevent the reflective layer (40) from reacting with air and oxidizing.

Hereinafter, a process for manufacturing colored glass according to an embodiment of the present invention will be described in order with reference to fig. 2 to 6.

Fig. 2 is a flowchart of a process for manufacturing colored glass according to an embodiment of the present invention, fig. 3 is a schematic diagram of a sand blasting process for forming a cushion layer having irregular uneven surfaces on one surface of a glass layer, fig. 4 is a scanning electron microscope photograph of a cushion layer formed by a sand blasting process, fig. 5 is a schematic diagram of a plasma process for stacking a first color layer on a cushion layer, and fig. 6 is a scanning electron microscope photograph of a cut surface of colored glass manufactured by a process for manufacturing colored glass according to an embodiment of the present invention.

First, a glass plate having a predetermined width, on which a glass layer (10) is formed, is prepared (S1).

Next, as shown in fig. 3, a cushion layer (20) is formed on one surface (11) of the glass layer (10) (or the back surface of the glass layer) by a conventional sand blasting (S2). The nozzle (70) is moved while spraying sand (71) of predetermined particles onto one surface (11) of the glass layer, thereby forming a mat layer (20) having irregular convexes and concaves (see fig. 4) on one surface of the glass layer. In this case, the underlayer (20) can be formed to a thickness (t1) of about 20nm to 50 nm.

Next, a first color layer (30) is stacked on the underlayer (20) using a plasma process (S3).

Specifically, as shown in fig. 5, the glass plate (1a) on which the spacer (20) is formed is loaded into the vacuum chamber (80). At this time, the glass plate (1a) is fixed to a holder (81) disposed in the vacuum chamber (80). In this state, a vacuum environment is formed in the vacuum chamber (80), various gases for the plasma process are supplied into the vacuum chamber (80), and then a voltage is applied to form plasma. At this time, as metal ions in a target (83) are deposited on the underlayer (20) by sputtering, the first color layer (30) is stacked on one surface (21) of the underlayer to form a predetermined thickness.

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

Next, a reflective layer (40) may be stacked on the first color layer (30) (S4). The reflective layer (40) can reflect light incident from the front surface of the colored glass back to the front surface of the colored glass again.

The reflective layer (40) may also be formed by a plasma process, in which case the object is formed of a different material than when the first color layer is formed. Referring to fig. 6, the reflective layer (40) may be formed to a thickness of about 25.3nm, which is in the range of a thickness (t3) of the reflective layer (30) of 20nm to 40 nm.

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

The second color layer (50) may also be formed by a plasma process as in the case of forming the first color layer and the reflective layer. In this case, the same material as that used when the first color layer is formed is used as the target. However, the stacked second color layer is formed to have a thickness thicker than that of the first color layer. That is, referring to fig. 6, the second color layer (50) is formed to have a thickness of about 233nm, which is a value falling within a range of a thickness (t3) of the second color layer (50) of 50nm to 300 nm.

Next, a transparent protection layer 60 may be stacked and formed on the second color layer (50) (S6). In order to form the protective layer (60), the colored glass stacked to the second color layer is extracted from the vacuum chamber, and then the silicon-based protective layer (60) is stacked on the second color layer (50) by a conventional spraying process or coating process.

In this case, the protective layer (60) is preferably formed to have a width capable of covering the entire second color layer (50) to prevent the second color layer (50) from coming into contact with air. Referring to fig. 6, the protective layer (60) may be formed to have a thickness of 33.8nm, which is a value falling within a range of a thickness (t5) of the protective layer (60) of 20nm to 50 nm.

The formation of the second color layer (30, 50) in the manufacturing process of the colored glass (1) according to one embodiment of the present invention has been described above. However, when the colored glass is viewed from the inside and outside of the building during the construction of the building, if the colors are not uniform, the process of forming the second color layer (50) may be omitted, and in this case, the protective layer (60) may be directly stacked on the reflective layer (40) to prevent the reflective layer (40) from being oxidized by the reaction with air.

The above drawings illustrate preferred embodiments of the present invention, but the present invention is not limited to the above specific embodiments, and those having ordinary knowledge in the art to which the present invention pertains can implement various modifications without departing from the gist of the present invention claimed in the scope of claims, and the implementation of these modifications should not be individually understood from the technical idea or the prospect of the present invention.
