Vacuum heating glass panel

In one embodiment of the present invention, a top pane glass; A lower plate glass opposed to the upper plate glass; Electrodes disposed on both end surfaces of the upper plate glass and the lower plate glass; A sealing part formed along an edge of the upper glass plate and the lower glass plate to seal the glass plate and the lower glass plate so as to form a vacuum layer in a space between the upper glass plate and the lower glass plate; And at least one filler that is formed in the vacuum layer and separates the upper glass plate from the lower glass plate.

1 is a plan view of a vacuum heat-generating glass panel according to an embodiment of the present invention. 2 is a cross-sectional view taken along the line A-A 'in FIG.

1 and 2, a vacuum heat generating glass panel 100 according to an embodiment of the present invention includes a top plate glass 110, a bottom plate glass 120, a sealing portion 140, and a filler 150.

The upper plate glass 110 and the lower plate glass 120 are spaced apart so as to face each other in parallel. The upper plate glass 110 and the lower plate glass 120 have a plate shape and are preferably designed to have the same area. Alternatively, the lower plate glass 120 may be designed to have a larger area than the upper plate glass 110.

The vacuum heating glass panel 100 may include the electrode 130 and may be disposed on both end surfaces of the upper and lower plate glasses. The vacuum heat-generating glass panel 100 may include the electrode 130 and power may be connected to the electrode connection terminal 160 to be described later.

In the case of applying a conventional vacuum glass panel to a dwelling house or the like, there have been various problems such as interference of visibility, damage of a window frame, breeding of mold bacterium due to an increase in humidity due to occurrence of dew condensation on a window, However, it was difficult to keep the insulation evenly to the edge portion, and there was a problem that the power consumption was very large.

However, since the vacuum glass panel 100 includes electrodes on both end surfaces of the upper and lower glass plates, it is possible to provide the vacuum glass panel with a heat generating function, and it is possible to secure heat resistance and dew condensation resistance, It can serve as heater for cost. Further, the present invention can be applied to household appliances such as a laboratory chamber or a refrigerator in which condensation resistance is essential.

The electrode may be, for example, a silver paste electrode, an aluminum paste electrode, a platinum paste electrode, a nickel paste electrode, or a carbon paste electrode. Specifically, the electrode may be formed by processing materials such as silver, aluminum, platinum, and nickel into a paste form or a tape form. For example, when a silver paste electrode having a high electrical conductivity is used, it is possible to form a uniform electrode having a certain level or more by preventing local floating phenomenon, and it is possible to easily produce an economical vacuum heating glass as compared with a platinum paste electrode Can be implemented.

Specifically, the silver paste electrode may be formed of a silver paste electrode composition including a silver paste, an organic solvent, and a binder. The silver paste may include about 60 parts by weight to about 80 parts by weight based on 100 parts by weight of the silver paste electrode composition. When the silver paste is less than about 60 parts by weight with respect to the silver paste electrode composition, there is a problem that the silver paste has a weak adhesive force between the silver paste and the upper plate glass and the lower plate glass and the electrode is easily transferred. When the silver paste is more than about 80 parts by weight, The viscosity increases and the dispersibility with other organic solvents and binders is lowered.

More specifically, the organic solvent includes a polar or non-polar solvent and is preferably selected from the group consisting of alpha-benzyl alcohol, methyl alcohol, ethyl alcohol, isopropyl alcohol, tetrahydrofuran, dimethylformamide, dimethylacetamide, The organic solvent is preferably selected from the group consisting of pyrrolidone, propylene carbonate, toluene, chloroform, distilled water, dichlorobenzene, dimethylbenzene, trimethylbenzene, pyridine, methylnaphthalene, nitromethane, acrylonitrile, octadecylamine, aniline, dimethylsulfoxide, , Alpha-terpineol, butyl carbitol acetate, and the like.

The binder may be used for increasing the adhesion of the silver paste to the upper plate glass and the lower plate glass, and may be about 1 part by weight to about 10 parts by weight based on 100 parts by weight of the silver paste electrode composition. When the content of the silver paste is less than about 1 part by weight, the adhesion between the silver paste and the upper plate glass and the lower plate glass is weak and the electrode film is easily transferred. When the content exceeds about 10 parts by weight, the conductivity of the formed electrode may be decreased . The binder may include at least one selected from the group consisting of silane, titanium oxide, glass frit water glass, spin-on glass, and combinations thereof.

The electrode may have a thickness of about 50 탆 to about 100 탆. When the thickness of the electrode is less than about 50 탆, there is a limit in forming a uniform electrode thickness by the silk screen method. When the thickness is more than about 100 탆, the drying process takes a long time. Therefore, it is possible to easily realize the effect of shortening the processing time by forming a uniform electrode thickness by maintaining the electrode thickness within the above range.

The vacuum heating glass panel may include an electrode connection terminal attached to the electrode. Specifically, the electrode connection terminal may include a top plate electrode connection terminal and a bottom plate electrode connection terminal. More specifically, an upper plate electrode connection terminal may be formed on the electrode of the upper plate glass 110, and a lower plate electrode connection terminal may be formed on the electrode of the lower plate glass 120.

The electrode connection terminal may protrude from an edge of the electrode. Specifically, the upper plate electrode connection terminal may be formed at an edge portion of the electrode formed on the upper plate glass, and the lower plate electrode connection terminal may protrude from the edge portion of the electrode formed on the lower plate glass. At this time, Power can be applied to the electrode connection terminal.

The electrode connection terminal may be formed of a thin film of copper, aluminum, silver, platinum or nickel, but is not limited thereto. For example, a copper foil and a nickel-copper alloy, and an aluminum, nickel-copper or nickel plated alloy may optionally be used.

The thickness of the electrode connection terminal may be about 100 탆 to about 300 탆. If the thickness of the electrode connection terminal is less than about 100 탆, there is a risk of physical damage such as breakage or detachment of the electrode due to an external impact. When the thickness exceeds about 300 탆, there is a limitation in processing and design. There is a concern that the double layered bedrock around the electrode may be exposed in the multi-layer process of the vacuum heat-generating glass panel. Therefore, by maintaining the thickness in the above range, it is possible to suppress the occurrence of a scratching or the like caused by an impact when the power is applied to the electrode connection terminal, and the probability of damage due to warping deformation can be reduced.

FIG. 3 illustrates an example in which power is applied to an electrode connection terminal of a vacuum heat-generating glass panel according to an embodiment of the present invention. When the power is applied to the electrode connection terminal, the vacuum heat generating glass panel generates heat and the calorific power can be controlled through the amount of current controlled by the current SCR controller. The temperature of the surface of the vacuum heat generating glass panel is controlled by controlling the amount of current according to the surface temperature by sensing the surface temperature of the vacuum heat generating glass panel due to the controlled heating value.

Specifically, the surface temperature of the top plate glass or the bottom plate glass may be about 20 ° C to about 30 ° C when the electrode connection terminal is powered on. When the surface temperature is less than about 20 캜, condensation may occur in winter. When the surface temperature exceeds about 30 캜, the heating value of the glass is higher than the winter heating temperature, resulting in a loss of heat to the room and consuming more power than necessary. Therefore, by keeping the surface temperature within the above-mentioned range, there is an advantage in that the dew condensation prevention function can be ensured and the energy consumption can be minimized.

The sealing part 140 is disposed along the edges of the upper plate glass 110 and the lower plate glass 120 so that the upper plate glass 110 and the lower plate glass 110 are separated from each other, And the lower plate glass 120 are sealed. Accordingly, the upper and lower plate glasses 110 and 120 are mutually opposed to each other by the sealing portion 140. [

The electrode 130 may be enclosed by the sealing portion 140. Specifically, the sealing part seals the upper plate glass 110 and the lower plate glass 120, and covers the electrodes disposed on both end surfaces of the upper plate glass and the lower plate glass.

The filler 150 is interposed in the vacuum layer between the upper glass plate 110 and the lower glass plate 120 to separate the upper glass plate 110 and the lower glass plate 120, It plays a role.

Also, it is preferable that the pillars 150 are arranged in a matrix arrangement with a spacing d in a plane, as shown in FIG. 1, disposed in the vacuum layer. The arrangement of the pillars 150 is for ensuring a constant thickness in the entire area of the vacuum heating glass panel 100 by minimizing the thickness deviation which is a problem at the edges and the central portion of the vacuum heating glass panel 100 .

As shown in FIG. 4, in the method of manufacturing the vacuum heat-generating glass panel, an upper glass plate 110 and a lower glass plate 120 are prepared by performing a cleaning process and a drying process (S100). Specifically, the upper glass plate 110 and the lower glass plate 120 are cleaned and dried in a cleaning chamber (not shown), and then the upper glass plate 110 and the lower glass plate 120 are cleaned by a transfer rail (not shown) It will come out.

Next, electrodes are formed on both end surfaces of the upper glass plate 110 and the lower glass plate 120 (S110). Specifically, the step of forming the electrode includes: applying a paste electrode composition to the both upper and lower end surfaces of the upper glass plate and the lower glass plate; And drying and curing the applied paste electrode composition.

A paste applying nozzle may be provided on both ends of the upper surface of the upper glass plate 110 and the lower glass plate 120 to apply the paste electrode composition. It is possible to prevent the risk of electrode damage and electric shock due to electrode exposure by applying the paste thinner than the sealing material to be coated later. The applied paste can be dried and cured at about 100 ° C to about 150 ° C for about 10 minutes to about 30 minutes.

By keeping the drying, curing temperature and curing time within the above-mentioned range, it is possible to sufficiently remove the solvent and the binder contained in the paste electrode composition and form a uniform paste electrode with less impurities.

The method may further include the step of inserting the electrode connection terminal after the step of forming the electrode. The electrode connection terminal can be inserted and fixed on the upper portion of the electrode formed by the drying and curing.

The electrode connection terminal includes a top plate electrode connection terminal and a bottom plate electrode connection terminal. Concretely, a top plate electrode connection terminal is formed on the electrode formed on the top plate glass 110, a bottom plate electrode is formed on the electrode formed on the bottom plate glass 120, The connection terminal can be inserted and fixed. The electrode connection terminal may protrude from the edge of the electrode, and the electrode connection terminal is as described above.

Next, the air between the upper and lower plate glasses 110 and 120 is evacuated to form a vacuum layer. Although not shown in detail in the drawings, the upper plate 110 may have an exhaust hole (not shown) passing through one corner of the upper plate 110, and the upper and lower plate glasses 110 and 120 The vacuum layer can be formed by evacuating the air of the vacuum chamber using a vacuum pump (not shown).

After the vacuum layer is formed, the sealing material is applied along the edge of the lower glass plate 120 to form the sealing part 130 (S120). Here, the sealing material is a material provided in the form of paste, for example, glass frit, is applied along the edge of the lower glass plate 120, and the sealing material thus coated is dried to form the sealing portion 140 can do.

After forming the sealing portion 140, at least one filler 150 is disposed on the upper surface of the lower glass plate 120 (S130). The fillers 150 are loaded and disposed on the upper surface of the lower glass plate 120 on which the sealing part 140 is formed by being carried using a suction nozzle (not shown) For example, in a matrix arrangement. At this time, a getter may be inserted into one side of the upper surface of the lower glass plate 120 separately from the arrangement of the pillars 150.

At least one filler 150 and a getter are mounted on the lower glass plate 120 and the upper glass plate 110 is disposed on the lower glass plate 120 so that the upper and lower glass plates 110 and 120 are attached to each other at step S140.

Hereinafter, specific embodiments of the present invention will be described. However, the embodiments described below are only intended to illustrate or explain the present invention, and thus the present invention should not be limited thereto.

Subsequently, the upper plate electrode connection terminal of the copper material thin film was inserted into the silver paste electrode of the upper plate glass, the lower plate electrode connection terminal was inserted into the silver paste electrode of the lower plate glass, and the sealing material was applied along the edge of the lower glass plate in the vacuum chamber . Also, at least one filler is disposed on the upper surface of the lower glass plate, the upper glass plate is disposed and heated on the upper glass plate, and the upper glass plate and the lower glass plate are adhered to each other to form a vacuum heating glass panel.

At this time, the top plate electrode connection terminal and the bottom plate electrode connection terminal were connected to the current SCR controller, and the surface temperature was measured through a thermocouple and a data logger by applying power. Using the dedicated glass heat conduction rate equipment manufactured according to KS F 2277 The heat conduction rate was measured without applying power.

Comparative Example 1

A vacuum heating glass panel was formed in the same manner as in the above example except that silver paste electrodes were not formed on both end surfaces of the upper and lower glass plates (hard roughening) and the upper surface of the lower glass plate (hard roughening) And the heat conduction rate was measured.

Comparative Example 2

(Power supply) Example Vacuum glass center side 0.9 W / m ² K -15 ℃ 25 ℃ 20 ℃ 25 ℃ Comparative Example 1 Vacuum glass center side 2.0W / m ² K -15 ℃ 25 ℃ 20 ℃ - Comparative Example 2 Loew Duplex Glass center side 2.7W / m ² K -15 ℃ 25 ℃ 15 ℃ 18 ℃

Referring to Table 1, in the case of the embodiment including the silver paste electrode, the heat conduction rate is 0.9 W / m ² K before power application, and the surface temperature (power source is not applied) is maintained at about 20 ° C. When the surface temperature (when the power source is not supplied) is about 20 ° C, central condensation does not occur, but partial condensation may occur at the edge of the glass that contacts the window frame.

Also, when the power was applied, the surface temperature was raised to remove condensation, but the surface temperature of the vacuum heat-generating glass of Example 1 was maintained at least 5 ° C even when the same power was applied.
