Description

Method for manufacturing a vacuum insulating glass panel using a multi-layer film and a vacuum insulating glass panel manufactured by the method

[0001] The present invention relates to a method for manufacturing a vacuum insulating glass panel using a film of multiple composite layers, and to a vacuum insulating glass panel manufactured by the method for manufacturing the same, and more specifically, to a method for manufacturing a vacuum insulating glass panel using a film of multiple composite layers, which is lightweight and has excellent durability and strength, thereby improving mechanical properties and maximizing sound insulation and heat insulation performance effects, by inserting a glass plate structure, in which a spacer is installed between a plurality of glass plates, into a film of multiple composite layers having a tube shape, and then forming a vacuum insulating space inside the glass plate structure through a vacuum processing process to complete the vacuum insulating glass panel. The present invention relates to a method for manufacturing a vacuum insulating glass panel using a film of multiple composite layers, and to a vacuum insulating glass panel manufactured by the method for manufacturing the same.

[0002] As minimizing environmental costs becomes a key business and national priority, energy-efficient design for all buildings is becoming essential.

[0003] Currently, standards for energy conservation, such as eco-friendly building certification and energy efficiency rating certification, are being strengthened in the construction of buildings.

[0004] When designing heating and cooling systems for the interior of a building, a large portion of energy loss occurs through the building's exterior, so insulating the exterior of the building is given significant weight in terms of energy conservation.

[0005] For example, insulating a building's exterior can save more than 50% of the building's energy loss.

[0006] Typically, thermal insulation systems are used to suppress phase change or temperature changes of substances in order to store and transport high or low temperature substances at room temperature and atmospheric pressure for efficient storage and transport.

[0007] Polymeric foam is widely used as the insulating material in insulation systems. Polymeric foam exhibits a trade-off between insulation performance and mechanical properties as the foam density decreases.

[0008] In other words, low-density foams offer excellent insulation performance, but their mechanical properties deteriorate. High-polymer foams offer excellent mechanical properties, but their insulation performance deteriorates.

[0009] In order to complement the characteristics of these polymer foams, a technology has been developed to reinforce low-density polymer foam with reinforcing materials such as glass fibers. However, due to the high thermal conductivity of the reinforced glass fibers, the thermal conductivity of the overall insulating structure increases even when the fiber volume fraction is low.

[0010] In the past, polyurethane, Styrofoam, and fiberglass were used as common materials for building insulation, and later, vacuum insulation panels (VIPs) with even better insulation performance were developed.

[0011] However, conventional vacuum insulation panels have the following disadvantages:

[0012] First, conventional vacuum insulation panels use adhesives to attach honeycomb cores and upper and lower surface plates, and an outer rubber seal between the upper and lower panels must be in close contact with the inner surfaces of the upper and lower panels to maintain the vacuum state of the vacuum space of the honeycomb core. Therefore, the manufacturing process is very complex and there is a problem in that productivity is significantly reduced.

[0013] Second, vacuum insulation technology using panels made of metal or plastic has been devised, but vacuum insulation panels using such metal and plastic panels minimize heat transfer through conduction and convection by forming a vacuum space between a pair of panels. However, when a vacuum space is formed between a pair of panels, the external atmospheric pressure presses the panels inward, causing the vacuum portion with insulating performance to disappear. In addition, in order to maintain the vacuum space, additional core material must be installed in the vacuum space. At this time, heat transfer occurs through the core material, and depending on the quality or shape of the core material, the problem arises that effective insulation is not achieved.

[0014] The present invention has been invented to improve the above-mentioned problems, and the problem to be solved by the present invention is to provide a method for manufacturing a vacuum insulating glass panel using a multi-composite layer film, which is lightweight, yet has excellent durability and strength, thereby improving mechanical properties and maximizing sound insulation and heat insulation performance effects, by inserting a glass plate structure having a spacer installed between a plurality of glass plates into a multi-composite layer film having a tube shape, and then forming a vacuum insulation space inside the glass plate structure through a vacuum processing process to complete the vacuum insulating glass panel, and a vacuum insulating glass panel manufactured by the manufacturing method.

[0015] As described above, the present invention has the following effects.

[0016] First, a vacuum insulation space is formed inside a glass plate structure (vacuum insulator) that maintains a constant distance between the glass plates by installing a spacer between multiple glass plates, so that it is lightweight, yet durable and strong, and can improve mechanical properties. It also has bulletproof glass performance, and when applied to buildings, it can minimize external impact even in the event of a natural disaster (e.g., an earthquake). It has excellent visibility and heat resistance with a light transmittance of over 92%, and has excellent UV stability.

[0017] Second, it maximizes energy saving effects as well as sound insulation and heat insulation performance, and can exhibit heat insulation performance, solar heat shielding effect, and condensation prevention function. When applied to the exterior of a building, it can create a clean and restrained appearance. It can satisfy the design characteristics of modern architecture that requires a clear view. When applied to the interior, it can create a bright and splendid indoor atmosphere. It can block solar heat while allowing a large amount of visible light to enter, and it is environmentally friendly as it significantly reduces heating and cooling costs and carbon dioxide (CO2) emissions by maintaining an appropriate indoor temperature all year round. In addition, the manufacturing and production process is simplified, so the initial equipment cost can be minimized and the production cost can be significantly reduced.

[0018] Third, the vacuum insulating glass panel technology of the present invention can be applied to various fields such as cargo holds of liquefied natural gas carriers, fuselages of airships and automobiles, or insulation materials for buildings.

[0019] Fourth, the vacuum insulating glass panel technology of the present invention can significantly reduce the weight of electric vehicles for cargo transport, thereby significantly increasing the battery usage time.

[0044] Referring to the drawings above, a method for manufacturing a vacuum insulating glass panel (100) according to an embodiment of the present invention comprises: a first step (S10) of manufacturing a multi-layer film (110) having a tube shape; a second step (S20) of manufacturing a glass plate structure (120) in which spacers (125) are installed between a plurality of glass plates (121) to maintain a constant distance between the plurality of glass plates (121); a third step (S30) of inserting the glass plate structure (120) into the tube of the film (110); a fourth step (S40) of blocking an opening of the tube of the film (110); and a fifth step (S50) of completing the vacuum insulating glass panel (100) by sucking and exhausting air inside the tube of the film (110) to the outside so that the film (110) is in close contact with the outside of the glass plate structure (120) and forms a vacuum insulating space (120a) inside the glass plate structure (120). It has technical features including:

[0045]

[0046] In the above first step (S10), as an example, the film (110) may be configured to include a metal foil deposition layer (10 μm); a nylon resin layer (20 μm); a TIE adhesive layer (10 μm); an ethylene vinyl alcohol barrier layer (20 μm); a TIE adhesive layer (10 μm); and an innermost heat-sealing layer (30 μm). The thickness of each layer may be changed according to design conditions.

[0047]

[0048] In the above first step (S10), as another example, the film (110) may be configured to include a protective layer (7 to 200 μm) (111) that absorbs and disperses external impact; a barrier layer (25 μm) (112) that is adhered to the lower portion of the protective layer (111) and blocks the inflow of external gas or moisture; and a heat-welding layer (50 to 150 μm) (113) that is adhered to the lower portion of the barrier layer (112) and adheres closely to the surface of the glass plate structure (120).

[0049] The thickness of each layer can be changed according to design conditions. A flame retardant coating layer with a flame retardant added thereto can be further formed on top of the protective layer (7-200 μm) (111).

[0050]

[0051] In the fourth step (S40), a vacuum suction tube (P) is inserted into the opening of the tube of the film (110) and sealed, and in the fifth step (S50), the internal air of the glass plate structure (120) is sucked and discharged to the outside through the vacuum suction tube (P) to form a vacuum insulation space (120a), and then the vacuum suction tube (P) is removed and finished.

[0052]

[0053] Meanwhile, as illustrated in FIGS. 5 and 10, a vacuum insulating glass panel (100) according to the present invention has a technical feature comprising a multi-layer film (110) having a tube shape; and a glass plate structure (120) configured to maintain a constant distance between a plurality of glass plates (121) by installing a spacer (125) between the plurality of glass plates (121), and then being inserted into the tube of the film (110) and then tightly pressed to form a vacuum insulating space (120a) for insulation therein.

[0054]

[0055] The above glass plate structure (120) maintains a constant gap between two or more glass plates (121) by interposing a spacer (125) between two or more glass plates (121), and the film (110) is adhered to the outer surface of the glass plate (121) to form a vacuum insulation space (120a) for insulation inside the glass plate structure (120).

[0056] The gap between the above glass plates (121) can be designed in various ways within the range of 0.1 to 30 mm, and the vacuum pressure of the vacuum insulation space (120a) can be designed to be 0.01 torr or higher.

[0057]

[0058] The above film (110) has an oxygen permeability (cc / m 2 .24h.atm); 0, moisture permeability (g / m 2 .24h.atm); 0, and thermal conductivity (kcal / mh℃) (or W / (m·k)); 0.0001 or less are technical characteristics.

[0059]

[0060] Furthermore, the film (110) has an oxygen permeability (OTR) (cc / m 2 .24h.atm): 10 0 ~10 -3 , moisture permeability (WVTR) (g / m 2 .24h.atm): 10 0 ~10 -3 Includes.

[0061]

[0062] The above film may include SiO2 / Al2O3 / TiO2 / AIN / SiON / ZnO / ZrO / Montmorillonite, which is a film corresponding to an encapsulation process that can function as a protective film to protect nano-elements such as OLED / QD.

[0063]

[0064] Since the film (110) of the present invention can be manufactured in a pouch shape (see FIG. 3) and a glass plate structure (120) can be inserted inside the tube, there is no need to consider formability for the container shape as in the existing technology, and there is no need to consider a separate film layer or cover part.

[0065]

[0066] As illustrated in FIG. 4, according to an example, the film (110) of the present invention may be configured to include a metal foil deposition layer (12 μm) (111); a nylon resin layer (15-20 μm) (112); a TIE adhesive layer (10 μm) (113); an ethylene vinyl alcohol barrier layer (20 μm) (114); a TIE adhesive layer (10 μm) (115); and an innermost heat-sealing layer (30 μm) (116). The thickness of each layer may be changed depending on design conditions.

[0067] The above film may include SiO2 / Al2O3 / TiO2 / AIN / SiON / ZnO / ZrO / Montmorillonite, which is a film corresponding to an encapsulation process that can function as a protective film to protect nano-elements such as OLED / QD.

[0068] In the present invention, when sealing the openings at both ends of a pouch-shaped film (110), the innermost layer, the heat-sealing layer (116), is made of linear low density polyethylene material, thereby enabling heat-sealing at a much easier temperature and time than conventional polypropylene material, and the weak moisture barrier property of the barrier layer of the ethylene vinyl alcohol film is supplemented by the innermost layer of linear low density polyethylene material.

[0069]

[0070] In addition, as illustrated in FIG. 6, according to another example, the film (110) of the present invention may be configured to include a protective layer (7 to 200 μm) (111) that absorbs and disperses external impact; a barrier layer (25 μm) (112) that is adhered to the lower portion of the protective layer (111) and blocks the inflow of external gas or moisture; and a heat-welding layer (50 to 150 μm) (113) that is adhered to the lower portion of the barrier layer (112) and is in close contact with the surface of the glass plate structure (120). The thickness of each layer may be changed according to design conditions.

[0071] It is desirable that the above barrier layer (25㎛) (112) has infrared and ultraviolet blocking functions (OTR=10 -0 ~10 -3 , WVTR=10 -0 ~10 -3 ).

[0072]

[0073] In addition, a flame retardant coating layer (114) with a flame retardant added thereto may be further formed on top of the protective layer (111), and an infrared (IR) blocking coating layer and a high heat resistance and impact resistance film layer may be further formed.

[0074] The above flame retardant coating layer (114) can be formed by coating a composition of 20 to 80 parts by weight of the flame retardant and 20 to 80 parts by weight of a polymer resin and an organic solvent on the upper part of the protective layer (113).

[0075]

[0076] The above flame retardant may be composed of one or more substances selected from phosphorus compounds, nitrogen compounds, aluminum hydroxide, and antimony trioxide.

[0077]

[0078] The above protective layer (111) can be formed by laminating one or more films selected from among polycarbonate films, polyimide films, nylon films, and PET (Polyethylene Terephthalate) films, each with a thickness of 7 to 200 μm, and the range of the protective layer thickness can be applied more widely.

[0079]

[0080] An inorganic layer made of aluminum or silica is formed on one side of the film forming the protective layer (111), and the inorganic layer can be formed to a thickness of 500 μm or less.

[0081]

[0082] The above barrier layer (112) can be formed by bonding an aluminum foil having a thickness of 5 to 100 μm and a PET film or EVOH (Ethylene Vinyl Alcohol) film having a thickness of 5 to 100 μm.

[0083] An inorganic layer made of aluminum or silica may be formed on either side of the PET film or the EVOH film.

[0084]

[0085] The above heat-welding layer (113) may be formed as a film made of one or more materials selected from among LLDPE (Linear Low-Density Polyethylene), LDPE (Low Density Polyethylene), HDPE (High Density Polyethylene), and CPP (Casting Polypropylene).

[0086] Furthermore, the heat-welding layer (113) may be formed as a film containing metallocene catalyst c4 to c8.

[0087]

[0088] The above heat-welding layer (113) has a thickness of 50 to 150 μm and has the characteristics of a degree of crystallization of 30% or more, a softening point of 70 to 130°C, and a melting point of 100 to 160°C.

[0089]

[0090] The above protective layer (111), barrier layer (112) and heat-welding layer (113) are each bonded using a polyurethane resin or polyester resin, and the interlayer bonding strength can be 200 gf / 15 mm or more.

[0091]

[0092] In a vacuum insulating glass panel (100) using a multi-layer film according to an embodiment of the present invention configured as described above, a glass plate structure (120) having a spacer (125) installed between a plurality of glass plates (121) is inserted into a multi-layer film (110) having a tube shape, and then a vacuum insulating space (120a) is formed inside the glass plate structure (120) through a vacuum processing to complete the vacuum insulating glass panel (100). By utilizing the principle that heat movement is blocked in a vacuum space (the principle that heat waves do not pass through), solar heat is effectively blocked to provide insulation performance, while sunlight (light waves) are allowed to pass through, so that a sufficient lighting effect can be obtained by allowing a large amount of visible light to enter, and an appropriate indoor temperature can be maintained in all four seasons, thereby reducing heating and cooling costs and significantly reducing carbon dioxide (CO2) emissions, thereby protecting the environment.

[0094] As described in Table 1 above, the vacuum insulating glass panel of the present invention has a thermal conductivity that is 15,000 to 35,000 times lower than that of conventional vacuum insulating glass panels, and is manufactured by maintaining a gap between the glasses and forming a vacuum insulating space inside the glass plate structure through a vacuum processing process, so that the gas barrier function is maintained even after a period of time, allowing for semi-permanent use. In addition, it has the advantage of being simple in manufacturing and being capable of various shape changes.

In this drawing, the same parts as the configuration of the vacuum insulating glass panel using a multi-layer film according to one embodiment of the present invention will be omitted.

[0101] Referring to the above drawing, in a vacuum insulating glass panel (200) using a multi-layer film according to another embodiment of the present invention, a support structure (130) can be further inserted and installed between a plurality of glass plates (121).

[0102] The above support structure (130) may be configured as a honeycomb structure.

[0103] The above honeycomb structure may be a structure in which a plurality of unit vacuum insulators in the shape of regular hexagonal columns with hollow spaces are continuously connected.

[0104] In this embodiment, a honeycomb structure support structure (130) is exemplified, but is not limited thereto, and may be changed to a shape other than a regular hexagon, such as a circle or other polygon.

[0106] First, a vacuum insulation space is formed inside a glass plate structure (vacuum insulation) that maintains a constant gap between the glass plates by installing a spacer between multiple glass plates, so that it is lightweight, yet has excellent durability and strength, and can improve mechanical properties. It also has bulletproof glass performance, and when applied to buildings, it can minimize external impact even in the event of a natural disaster (e.g., an earthquake). It has excellent visibility with a light transmittance of over 92%, excellent heat resistance, and excellent UV stability.

[0107] Second, it maximizes energy saving effects as well as sound insulation and heat insulation performance, and can exhibit heat insulation performance, solar heat shielding effect, and condensation prevention function. When applied to the exterior of a building, it can present a clean and restrained appearance. It can satisfy the design characteristics of modern architecture that requires a clear view.
