Technical Field

The invention relates to the field of glass manufacturing, in particular to a heat-insulating shielding glass panel.

Background

According to the specification of double glazing performance provided by the "high performance glass promotion conference", the solar radiation heat gain ratio is required to be 0.51 (this value represents that 51 units of solar radiation heat reach the indoor space based on 100 units of solar radiation heat) or less. Further, according to the next-generation energy saving standard released in 3 months of 2000 by the ministry of international trade and industry and the ministry of construction, it is required to set the solar radiation heat gain ratio at any of regions III, IV and V b. e 0.49 (which means that 49 units of solar radiant heat reach the indoor space based on 100 units of solar radiant heat) or less, and this ratio is more preferable. Double glazing units have been developed which have not only heat insulating properties but also heat insulating properties. For example, japanese patent No. 2882728 discloses a double-glazing panel in which a sheet of colored heat ray absorbing glass is provided on the outdoor side, a sheet of transparent type glass is provided on the indoor side, and a low emissivity film is formed in the room. A colored heat absorbing glass sheet is placed outside the room. The above double glass panel produces a window glass that is too thick because it is necessary to obtain an air layer (or a gas layer such as an argon layer) between two sheets of glass with a thickness of 6mm or more in order to obtain heat insulating performance. For example, when the thickness of each glass plate is 3mm and the thickness of the air layer is 6mm, the thickness of the window glass reaches even 12mm, and thus it is hardly used in general houses. Accordingly, a vacuum glass panel having a very thin vacuum layer with a thickness of 0.2mm, which is between two sheets of flat glass, has been developed, and the structure thereof is the same as in the above-described double glass panel. This type of vacuum glass panel provides a sufficiently thin window glass, and inhibits solar radiant heat from entering the interior of a room during hot summer days without losing the cooling to the outside at night provided by the refrigerator, thus improving cooling efficiency due to the effects of the heat absorbing glass and the low emissivity film. In addition, this type of vacuum glass panel also improves heating efficiency in winter, and thus is widely used as energy-saving window glass.

Disclosure of Invention

The present invention has been made to overcome the above-mentioned disadvantages of the prior art and an object of the present invention is to provide a heat insulating and shielding glass panel which is sufficient in heat insulating property and does not warp even when receiving solar radiation.

The technical scheme of the invention is as follows: by forming a gap layer having a predetermined interval between a pair of sheet glasses, a sealed outer peripheral portion is formed along the outer peripheries of the two sheet glasses, thereby separating an indoor space and an outdoor space. And sealing the gap layer in a decompressed state, characterized in that a functional film having an emissivity of 0.20 or less is formed on a surface of the chamber-outside plate of the sheet glass which is in contact with the gap layer; the flat glass sheet on which the functional film is formed is 45% or less, the flat glass sheet on which the functional film is formed has a solar radiation absorptance of 25% or less, and the following relationship holds: solar radiation absorptivity (1.02) × solar radiation reflectivity + 48.5.

Detailed Description

In FIG. 1, the present invention is formed with a functional film 5 layer characterizing the present invention on the side of the gap layer 4 of the side plate glass 2. In manufacturing such a glass panel, first, the functional film 5 is formed on one surface of a float glass sheet or the like by sputtering or the like to prepare the outdoor side plate-shaped glass sheets 2, and the spacer 6 is interposed between the plate-shaped glass sheets 2 a. An indoor side plate 3 of a plate glass. The spacer 6 is made of a material having a compressive strength of 4.9 x 108Pa or more, such as stainless steel, preferably a solid cylinder having a diameter of 0.3mm to 1.0mm and a height of 0.15mm to 1.0 mm; the gap layer 4 is formed between the two sheets of plate glass by adhesively sealing the peripheries of the two sheets of plate glass with the spacer 6 sandwiched by low-melting glass along the peripheries of the two sheets of plate glass, and then the pressure in the gap layer 4 is reduced by sucking air therein, and the gap is laid. ER 4 is tightly sealed so as to be in a state of showing an environment having a pressure of 1.33Pa or less. The functional film 5 is a laminated film having a structure in which a dielectric layer and a metal layer constitute a main layer, for example, a laminated film composed of a first dielectric layer/a metal layer/a second dielectric layer, or the like. Of these layers, silver is recommended as the metal in the metal layer; alternatively, silver doped with palladium, gold, indium, zinc, tin, aluminum, copper, or the like can also be preferably used. In addition, the thickness of the metal layer is preferably 10 to 18 nm. As the main component of the material for the dielectric layer, one or more oxides selected from oxides of zinc, tin, titanium, indium, and bismuth; in addition, for the at least one dielectric layer, one or more oxides selected from nitrides may be used. Layers of metals containing Si, Al and Ti and oxynitride layers may be used. In addition, the thickness of the first dielectric layer is preferably 10 to 90nm, and the sum of the total thicknesses of the second dielectric layers is preferably 10 to 60 nm. Further, when the dielectric layer is formed by reactive sputtering, a sacrificial layer may be inserted to an interface far from the glass plate, an interface between the dielectric layer and the metal layer, the sacrificial layer being composed of metal or Me. Ta oxides, which are themselves oxidized to prevent deterioration (oxidation) of the formed metal layer. Specific examples of the material constituting the sacrificial layer include metals such as titanium, zinc, silicon, aluminum, zinc/tin alloy, and niobium, and oxides of these metals. In addition, the thickness of the sacrificial layer is suitably 1 to 5 nm. Therefore, for example, the following configuration is involved: glass/ZnO/Ag/Ti/ZnO/SiNx; glass/ZnO/Ag/Ti/SiNx/ZnO/SiNx; glass/ZnO/Ag/Ti/SiNx, etc. In addition, a SiO2 layer may be formed as the uppermost layer, i.e. the layer furthest from the surface of the sheet glass. By forming the SiO2 layer as the uppermost layer, foam formation caused by reaction of the functional film 5 with an adhesive sealing material such as low-melting glass and metal solder during adhesive sealing can be suppressed; the sealing material can be easily inserted into the gap layer 4 between the plates of the flat glasses 2 and 3. In addition, a SiO2 layer may be formed as the lowest layer, i.e., the layer closest to the surface of the flat glass sheet. By forming the SiO2 layer as the lowermost layer, the influence of a layer higher than the lowermost layer in the surface state of the flat glass sheet can be prevented, and a film can be stably formed.
