Abstract

The present invention relates to a multilayered glass with a conspicuously improved energy-saving function. The multilayered glass is manufactured so that a coated layer is arranged at the inner space of a paint layer by coating one side of a plate glass at regular intervals with paints, which can prevent or reflect light, and incident light to the coated layer among incident light to the multilayered glass is prevented or reflected, thereby remarkably reducing radiant heat due to infrared rays included in the light. By doing this, the heat insulation property of the multilayered glass is conspicuously enhanced, thereby obtaining an energy conservation effect. The present invention is about the functional multilayered glass of the structure.

Description

The improved pair glass with insulating performance}

The present invention relates to a multilayer glass that has dramatically improved the energy saving function.

This is made of laminated glass coated with a material that blocks or reflects light at regular intervals, thereby blocking or reflecting all light incident on the surface, thereby dramatically increasing the thermal insulation performance of the laminated glass. The invention relates to a multilayer glass that can be obtained.

In general, about 30% of the building's heating and cooling energy consumption is lost through windows.

Many technologies are being developed around the world to reduce this energy loss. A typical practical example is to use a laminated glass, a triple glass, a vacuum glass, a low-E glass, such as a reflective coating glass or colored glass using colored glass for the window.

In general, the laminated glass is produced by adhering the plate glass on both sides of the frame member in the form of a frame.

Multi-layered glass has been widely used as window materials of buildings in recent years because it is possible to obtain sound insulation and excellent thermal insulation effect by the space formed between the glass plates.

However, these multilayer glass has an insulation layer formed in the inner space can effectively block the convective heat, but there is a limit that can hardly block the radiant heat by far-infrared rays included in the sunlight.

This is because the nature of the glass window should be transparent so that the inside and the outside can be seen, which can hardly prevent the passage of far-infrared rays which directly affect the thermal conductivity. This is the reason why the solar heat acquisition rate (SHGC) of laminated glass cannot be reduced.

Therefore, the conventional technology uses some expensive Roy glass or colored glass to reduce the light transmittance and increase the reflectance of incident light to block the passage of far infrared rays, thereby lowering the solar heat acquisition rate (SHGC) and reducing the heat transmittance (U-Value). Lowering is best. The laminated glass thus produced is known as a laminated glass having the highest thermal insulation at present.

The present invention can effectively block the heat caused by convection or conduction of the conventional laminated glass, but can hardly block the radiant heat caused by the transmission of far-infrared rays. Multilayer glass is made of glass coated with metal thin film that blocks and reflects light at regular intervals. By blocking most of the far-infrared rays incident on the window and reflecting it, it suppresses radiant heat. It is to provide a laminated glass.

The present invention, in order to compensate for the shortcomings (disadvantage of not being able to effectively control the radiant heat) of the laminated glass produced by the prior art described above coated a barrier film or metal reflective thin film at regular intervals on one surface of the laminated glass. shall.

Coating light-blocking materials on the glass surface can be easily printed with various printing methods using paints or inks. Coating metal thin films can be done by vacuum evaporation or vacuum spattering. A thin film can be formed using a sputtering method. Of course, in this case, it is possible to fabricate using a masking method to form a metal thin film on one side of the plate glass, which will be described in detail in the next chapter.

When the multilayer glass is manufactured by using a plate glass formed with a coating film or a metal reflective thin film which can partially block light, the multilayer glass having a function of suppressing radiant heat by effectively blocking or reflecting the transmission of far infrared rays pursued by the present invention is produced. It can be.

When the multilayer glass is manufactured using the plate glass having the coating surface formed in this way, the multilayer glass having a function of suppressing radiant heat by blocking the transmission of far infrared rays pursued by the present invention can be made.

As described above, the present invention provides a functional plate glass in which the coated surface and the transparent surface are formed in a predetermined shape in order, and also provides a functional multilayer glass including one sheet or two or three sheets of the functional sheet glass. .

According to the present invention, the laminated glass made of the functional plate glass having a coated surface and a transparent surface at regular intervals is because some or most of the incident light is blocked or reflected by the coating surface and cannot pass through, so that radiant heat due to far infrared rays Significantly suppressed energy savings are greatly improved.

    In addition, the multilayer glass according to the present invention has a great effect on looking out from the inside as if the coating surface coated at regular intervals hits the foot, but from the outside, the interior is not easily visible due to the interference of the coating surface. There is also a useful advantage.

In addition, the color or shape of the coated surface can be freely configured, which also has the advantage of creating a unique design on the glass window.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

The present invention provides a multi-layered glass composed of a functional plate glass having a technical feature that the shielding film that can block the light on the plate glass or the metal thin film that can block and reflect the light is formed at a constant intersection with the transparent surface.

Plate glass, a term used in the present invention, is a comprehensive concept including general transparent glass, color glass, Roy glass, and the like.

The present invention provides a functional plate glass is formed with a coating surface at regular intervals as shown in FIG.

The surface on which the coating surface is formed to block or reflect light (called "coating surface") and the transparent surface on which the coating surface is not formed (called "transparent surface") maintain a constant area ratio. Formed.

The area ratio means the area ratio of the coated surface and the transparent surface (area ratio (r) = coating surface / transparent surface), and this area ratio may be determined according to the characteristics of the product and the needs of the user.

In the present invention, 0.5 ≤ r ≤ 1 can be an embodiment, and the form within this range is most preferable in terms of economic and functional.

In addition, the coating surface forming structure in the present invention has a structure in which the coating surface maintains a linear and pattern of a constant width.

Forming a certain linear and pattern means that the coating surface is formed while forming a certain form, type or shape as shown in Figure 1, 2, 3.

The following description shows various embodiments in which the coated surface and the transparent surface are formed at regular intervals in the plate glass which is a technical feature of the present invention. Therefore, the technical idea of the present invention is not limited to this embodiment and includes any structure or shape in which the coated surface and the transparent surface are formed in a certain shape on the plate glass.

1, 2, and 3 show a typical form in which the coated surface and the transparent surface of the plate glass are formed, and the width and the spacing of the coated surface and the transparent surface can be adjusted as necessary.

As described above, the present invention is a technical feature that the coating surface and the transparent surface to maintain a constant ratio on the plate glass, the coating surface and the transparent surface are formed in order.

Since the coating is partially formed on the plate glass in the present invention, the effect of blocking or reflecting light (sunlight, room light, etc.) is created.

Therefore, the effect of blocking and reflecting light may be adjusted by varying the area ratio of the coated surface and the transparent surface according to the needs of the user.

In the present invention, the "coating surface" coated on the plate glass means a structure or shape such as a coating layer formed in the form of a thin film that functions to block or reflect light.

In the present invention, the coating surface and the transparent surface are formed in order as described above, so that the light incident on the transparent surface passes as it is, and the light incident on the coating surface is blocked or reflected as it is, thereby preventing the glass from penetrating.

For example, if a transmittance of 50% is desired, the ratio of the coated surface and the transparent surface may be set to 50:50. Of course, this is based on the assumption that the light transmittance of the transparent surface is 100%, and can be calculated by considering the surface reflectance (about 4%) of the transparent glass.

As described above, in the present invention, the coated glass at regular intervals reduces the transparent surface when the coating surface is widened, and the transparent surface decreases, and the coating surface decreases when the transparent surface is widened, so that the blocking and reflection effects of incident light are reduced. It is desirable to adjust according to the environment and the characteristics of the product.

As described above, various methods may be employed to fabricate the coating surface and the transmission surface at a predetermined interval on one surface of the plate glass.

To obtain a coating surface for the purpose of light blocking only, it is possible to simply print the paint or ink on the plate glass by various printing methods.

In order to obtain a coated surface of the metal thin film that can block light and reflect light, a desired purpose can be achieved by using a vacuum evaporation method or a vacuum sputtering method. When the laminated glass is made using the functional plate glass thus made, the laminated glass of the present invention is completed.

The process of the present invention will be described in detail below.

1. Functional plate glass manufacturing process of the present invention

Functional glass plate production of the present invention can be carried out using the following two methods as shown in FIG.

(1) Method of forming coating surface with paint or ink

Wash and dry the plate glass (S1).

One side of the plate glass is printed at regular intervals with paint or ink to form a coated surface. (S2)

Then dry (S3) to produce a glass plate formed with a light shielding coating surface and a transparent surface at regular intervals.

(2) Method of forming a coating surface with a metal thin film

Wash and dry the plate glass (S1).

On one side of the plate glass, the metal thin film is coated at regular intervals using vacuum evaporation, vacuum sputtering and masking.

It is easy to coat the metal thin film on one side of the sheet glass, but it is almost impossible to partially coat the metal thin film at regular intervals as described above.

     To solve this problem, there are generally two methods using the masking method.

In the first method, a thin film of metal is coated on one side of the washed and dried pane with any material, then printed and masked on the coating to be left to dry to form a masking surface, and chemical etching. If the unmasked coating is melted and removed by the process and reduced to a transparent surface, only the portion protected by the masking surface remains.

Secondly, a process of forming a masking surface by attaching a masking tape or printing with masking ink on a portion to be left as a transparent surface and drying it is performed in the opposite manner to the above method (S2-1).

Then, coating an arbitrary metal thin film (S2-2), and then removing the masking surface made of masking tape or printed masking ink (S2-3) and reducing it to the transparent surface, only the metal thin film surface coated on the unmasked portion Will remain.

In this case, as the thin film coating material, a metal such as AL (aluminum), Ag (silver), CR (chromium), Ni (nickel), an alloy thereof, or a metal oxide may be used.

Among them, AL is most preferred.

AL is inexpensive, has the easiest vacuum deposition, and the coating is more reflective than other metals. When AL coating is over 600Å (Angstrom, 1Å = 1mm / 1mm) thickness, it completely blocks the transmission of light and shows high efficiency reflectivity of 80 ~ 85%.

Coating with another metal, Ni or CR or its alloys or metal oxides has the advantage of better adhesion to the glass surface than AL and a harder surface of the coating, but it is more difficult to work (expensive to produce) and light It can block, but the reflectivity of the coating is lower than AL. Only AL coatings and other colors can be chosen for their excellent design.

2. Laminated Glass Manufacturing Process [FIG. 9]

The functional glass plate completed through the above process is washed again, dried and subjected to quality inspection. (P1)

The inspected functional sheet glass is bonded to both sides of the frame-shaped spacer to make a multilayer glass (P2).

In the present invention, the term "laminated glass" refers to a window in which glass is made of double or more, and includes a multilayer glass and triple laminated glass.

As shown in FIG. 4A, the present invention includes a plate glass 100 having a coating surface formed at regular intervals on one surface thereof, and providing a multilayer glass including the general plate glass 200.

Therefore, the functional multilayer glass of the present invention can be seen that the coating surface is formed of a plate glass 100, a spacer 300, a general plate glass 200 formed at regular intervals.

In this case, depending on the area ratio of the coated surface and the transparent surface, only the effect of the same ratio can be obtained regardless of the incident angle of the incident light.

In any case, it is preferable to position the surface on which the coated surface is formed on the inner surface of the laminated glass to prevent damage to the coating.

As another example, Figure 4b shows a laminated glass formed so that the two plate glass formed at regular intervals of the coating surface facing each other. Such laminated glass is a representative laminated glass consistent with the object of the present invention.

Such a functional multilayer glass can be seen that the coating surface is formed of a plate glass 100, spacer 300, the plate glass 110 is formed with another coating surface at regular intervals.

In this case, the coated surface and the transparent surface formed on the front and rear two panes 100 and 110 should be installed exactly facing each other (FIG. 4C). By doing so, it is possible to obtain the effect of increasing the effect of the area ratio of the coated surface and the transparent surface up to twice according to the angle of the incident light.

Figure 4d shows the form formed so that the coating surface of the two panes formed on both sides intersect horizontally and vertically.

The light blocking action of the laminated glass configured as described above will be described as follows.

As shown in FIG. 4C, in the above-described functional multilayer glass, the width b of the coated surface and the width a of the transparent surface a, the distance between the coatings, and the distance c between the two panes formed by the spacer 300 are Assuming the same case, the ratio of the amount of light transmitted and the amount of reflected light changes according to the incident angle of light.

As shown in FIG. 5A, if light is incident on the glass surface of the multilayer glass in front (when the incident angle θ is 0 degrees), the coating surfaces formed on the two glass plates correspond to each other with respect to the horizontal surface, and also the area of the coating surface and the transparent surface. Since the ratio is the same, 50% of the incident light is blocked and reflected, and 50% is passed through it (in this case, the natural reflectance of the transparent surface is assumed to be 0).

However, as shown in FIG. 5B, when light is incident on the glass surface of the multilayer glass at a 45 ° angle, 100% of the light is blocked and reflected.

That is, 50% of the incident light is blocked or reflected by the coating surface of the front pane 110, and the light incident through the transparent surface of the front pane 110 is blocked or reflected by the coating surface of the back pane 100. 100% of the light is blocked or reflected.

As such, the amount of light blocked or reflected is changed from 50% to 100% according to the angle of incidence of light, and the amount of light that is blocked by the far-infrared rays contained in the light is blocked, thereby reducing the total radiant heat.

Such a function of the functional laminated glass of the present invention can significantly lower the solar heat acquisition rate (SHGC) of the laminated glass, thereby significantly increasing the thermal insulation performance of the laminated glass.

In addition, even if the laminated glass of the present invention is made of inexpensive plain glass without using expensive Roy glass or colored glass, there is an economical advantage that can increase the thermal insulation effect by lowering the heat transmittance (U-Value) than the Roy glass.

In addition, the present invention can obtain a more sure effect if the above-described coated glass formed at regular intervals to the triple glass (FIGS. 6A, 6B, 6C).

The present invention provides a multi-layer glass having a heat insulating effect due to light blocking and reflection characterized in that the coating surface is formed at regular intervals.

The present invention is a very useful invention to enable the adoption of a new concept of energy saving technology in the multi-layer glass production industry for increasing the thermal insulation.

In addition, the present invention is a very useful invention that satisfies the energy-saving needs in the field of construction and construction to handle the window system using glass.
