Description

Technical Field

[0001] This utility model relates to the field of tempered glass technology, and more specifically, to a low-emissivity insulated tempered glass. Background Technology

[0002] Low-emissivity (LEE) tempered insulated glass is a high-performance architectural glass that integrates energy saving, safety, and sound insulation. It is made by combining LEE coated glass with tempered glass using insulated technology. Its core component is a LEE film composed of metallic silver or other metal oxides coated on the surface of the tempered glass, which is then combined with other glass panes to form a sealed insulated layer. LEE tempered insulated glass has become a core material for building energy conservation. Driven by policy and market forces, its application has expanded from high-end commercial buildings to residential buildings, renovation projects, and smart buildings.

[0003] In practical use, low-emissivity tempered insulated glass is susceptible to thermal expansion and contraction due to seasonal changes or ambient temperature. This can easily lead to cracks or gaps in the sealed area. When outside air or water vapor enters the insulated layer, the water vapor can form condensation on the glass surface. The air can then react with the low-emissivity film, causing it to oxidize and ultimately fail. Therefore, improving the sealing performance of low-emissivity tempered insulated glass can extend its lifespan and reduce replacement costs. Utility Model Content

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figures 1 to 5As shown, this utility model discloses a low-emissivity hollow tempered glass, which includes a first tempered glass plate 100, a second tempered glass plate 200, and a sealing component 300. The first tempered glass plate 100 and the second tempered glass plate 200 are arranged in parallel, and a hollow cavity 210 is formed between the first tempered glass plate 100 and the second tempered glass plate 200. The hollow cavity 210 is filled with an inert gas, which is a mixture of 90% argon and 10% krypton, balancing heat insulation and cost. A low-emissivity film is provided on the side of the first tempered glass panel 100 and / or the second tempered glass panel 200 near the hollow cavity 210. The low-emissivity film can selectively reflect long-wave infrared radiation, thereby effectively blocking indoor heat loss to the outside or outdoor heat transfer to the inside. In cold seasons, the heat emitted by indoor objects is mainly emitted towards the window in the form of long-wave infrared radiation. The low-emissivity film can reflect this heat back into the room, reducing heat loss. In hot seasons, the low-emissivity film can also reflect some mid- and far-infrared thermal radiation from the outside, helping to reduce the cooling load and significantly improving the overall energy-saving and heat-insulating efficiency of the glass. At the same time, the inert gas in the hollow cavity 210 can prevent the low-emissivity film from oxidizing and failing. In this embodiment, the low-emissivity film can be a double-silver high-transmittance Low-E film.

[0034] Reference Figures 1 to 3As shown, the sealing assembly 300 has a frame spacer 310 around the hollow cavity 210. A first wing plate 320 and a second wing plate 330 are respectively provided on both sides of the frame spacer 310. The first wing plate 320 abuts against the first tempered glass plate 100, and the second wing plate 330 abuts against the second tempered glass plate 200. A sealing adhesive layer 340 is provided on the side of the frame spacer 310 closest to the hollow cavity 210, and a structural adhesive layer 350 is provided on the side of the frame spacer 310 furthest from the hollow cavity 210. The two sides of the structural adhesive layer 350 extend towards and wrap around the outer edges of the first and second tempered glass plates 100 and 200. The sealing assembly is arranged around the hollow cavity 210, with the frame spacer 310 serving as its core supporting component. The first wing plate 320 and the second wing plate 330 are respectively connected to the two sides of the frame spacer 310. The first wing plate 320 directly abuts against the first tempered glass plate 100, and the second wing plate 330 directly abuts against the second tempered glass plate 200. In this embodiment, the first wing plate 320 and the second wing plate 330 are constructed as flexible spring-like structures. This structure allows the first wing plate 320 and the second wing plate 330 to undergo elastic bending deformation when subjected to external forces, and to tend to return to their original shape after the external forces are removed. When the first tempered glass plate 100 and the second tempered glass plate 200 expand and contract due to seasonal changes or diurnal temperature variations, the glass plates will experience slight positional changes relative to the frame spacer 310. At this time, the first wing plate 320 and the second wing plate 330, acting as springs, can absorb the stress caused by the displacement of the glass plates through their own elastic bending deformation. This elastic deformation can buffer the rigid compression or tension of the glass plates on the frame spacer 310, preventing cracks or gaps from forming at the sealed joint due to excessive stress concentration. The sealing adhesive layer 340 on the side of the frame spacer 310 closest to the hollow cavity 210 directly prevents the inert gas filling the hollow cavity 210 from leaking outwards, while also preventing water vapor molecules from the external environment from penetrating into the hollow cavity 210. The structural adhesive layer 350 on the side of the frame spacer 310 furthest from the hollow cavity 210 provides structural bonding force, firmly binding the frame spacer 310, the first tempered glass plate 100, and the second tempered glass plate 200 into a single unit. The two sides of the structural adhesive layer 350 further extend towards the outer edges of the first tempered glass plate 100 and the second tempered glass plate 200 and wrap around the glass edges, forming a secondary sealing barrier on the outside to resist the intrusion of external liquid water and air. Through the design of this structure, the spring-loaded structure of the first wing plate 320 and the second wing plate 330 can actively adapt to the thermal expansion and contraction deformation of the glass plate through its own elastic bending, effectively protecting the sealing layer 340 and the structural adhesive layer 350 from direct damage by excessive stress, and greatly reducing the possibility of microcracks or gaps in the sealing area due to repeated temperature changes.The sealing system, supported by the first wing plate 320 and the second wing plate 330 with spring function, together with the sealing adhesive layer 340 and the structural adhesive layer 350, can form multiple protections against gas leakage, oxidation failure and fogging problems, significantly improving the long-term sealing reliability and service life of low-emissivity insulated tempered glass in complex thermal environments.

[0035] In some embodiments of this utility model, the frame spacer 310 has a plurality of first grooves 311 on the side near the sealant layer 340. Specifically, in this embodiment, the frame spacer 310 is located on the periphery of the hollow cavity 210, and the first wing plate 320 and the second wing plate 330 on both sides abut against the first tempered glass plate 100 and the second tempered glass plate 200, respectively. The elastic sheet structure of the first wing plate 320 and the second wing plate 330 can absorb the displacement stress of the glass plate caused by temperature changes through elastic bending. On the side of the frame spacer 310 near the hollow cavity 210, which is the key area where the sealant layer 340 needs to be set to prevent leakage of inert gas mixture and water vapor penetration, the presence of these first grooves 311 allows the sealant to be embedded and fill the internal space of the first grooves 311 during the coating and curing process. When the sealant fills the first grooves 311, it can significantly increase the actual contact area and mechanical interlocking strength between the sealant layer 340 and the frame spacer 310, forming a more solid physical anchor. This enhanced anchoring effect effectively resists creep or potential peeling from the frame spacer 310 surface that may occur during long-term service of the sealant layer 340, ensuring that the sealant layer 340 remains tightly adhered to the frame spacer 310 for a long period. Furthermore, the structure of the first groove 311 guides and accommodates the sealant to form a specific shape on the surface of the frame spacer 310. This facilitates a certain degree of adaptive deformation of the sealant layer 340 in the groove area when subjected to periodic stresses caused by the thermal expansion and contraction of the glass plate transmitted by the first flange 320 and the second flange 330. This disperses stress concentration points and prevents excessive stress concentration in localized weak areas of the sealant layer 340, which could lead to microcracks.

[0036] In some embodiments of this utility model, the sealant layer 340 is butyl rubber.

[0037] In some embodiments of this utility model, a plurality of second grooves 312 are provided on the side of the frame spacer 310 near the structural adhesive layer 350. Specifically, in this embodiment, the design of the second grooves 312 allows the structural adhesive to be fully embedded in and fill the internal space of the second grooves 312 during application. When the structural adhesive cures and fills the second grooves 312, it can significantly increase the actual contact area between the structural adhesive layer 350 and the frame spacer 310, and form a deep mechanical interlocking engagement. This can greatly improve the ability of the structural adhesive layer 350 to resist peeling and shear stress, ensuring a long-term firm bond between the frame spacer 310, the first tempered glass plate 100, and the second tempered glass plate 200, effectively resisting external mechanical loads such as wind pressure and vibration. The structure of the second groove 312 can guide the structural adhesive to form a more optimized adhesive distribution pattern on the surface of the frame spacer 310. When the structural adhesive layer 350 is subjected to periodic stress transmitted to its edge interface by the thermal expansion and contraction of the first tempered glass plate 100 and the second tempered glass plate 200, the structural adhesive filled in the second groove 312 can absorb and disperse these stresses through small adaptive deformations, avoiding excessive stress concentration at the bonding interface or local area between the structural adhesive layer 350 and the frame spacer 310, thereby reducing the risk of interface peeling or microcracks generated inside the adhesive.

[0038] In some embodiments of this utility model, the structural adhesive layer 350 is a combination of one or more of silicone structural adhesive, polysulfide structural adhesive, or polyurethane adhesive.

[0039] In some embodiments of this utility model, a receiving cavity 313 is provided inside the frame spacer 310, and a slit 314 is provided on the frame spacer 310, with the receiving cavity 313 communicating with the slit 314; the receiving cavity 313 is filled with a molecular sieve. Specifically, in this embodiment, the receiving cavity 313 is located inside the frame spacer 310, and the molecular sieve filled inside is a drying material with a high efficiency in adsorbing water vapor. The slit 314 serves as a gas channel, enabling a slow gas exchange between the inert gas inside the hollow cavity 210 and the molecular sieve inside the receiving cavity 313. When the inert mixed gas inside the hollow cavity 210 flows through the slit 314 into the receiving cavity 313 and contacts the molecular sieve, water vapor molecules that may be present in the gas or that later infiltrate in small amounts can be efficiently adsorbed and captured by the molecular sieve. The molecular sieve's ability to continuously adsorb water vapor significantly reduces the humidity level inside the hollow cavity 210. Even trace amounts of water vapor molecules that slowly permeate into the hollow cavity 210 through the sealing layer 340 can be promptly adsorbed and removed by the molecular sieve. Maintaining an extremely low humidity level inside the hollow cavity 210 fundamentally prevents water vapor from condensing on the inner surface of the first tempered glass plate 100 or the second tempered glass plate 200 during temperature changes, ensuring the clarity and visual appeal of the glass. Simultaneously, the extremely low humidity environment reduces the potential erosion of the low-emissivity membrane by water vapor, and together with the oxygen-isolated sealing design, protects the long-term functional stability of the low-emissivity membrane. The design of the molecular sieve housing 313 and its connecting slits 314 integrates the desiccant within the frame spacer 310, effectively utilizing space.

[0040] In some embodiments of this utility model, reference is made to Figures 1 to 3As shown, a honeycomb structure 315 is provided inside the receiving cavity 313. Specifically, in this embodiment, the frame spacer 310 serves as the core support of the sealing assembly 300, and its internal receiving cavity 313 is connected to the hollow cavity 210 through a slit 314. The molecular sieve filled in the receiving cavity 313 is responsible for adsorbing trace amounts of water vapor in the inert mixed gas inside the hollow cavity 210. The honeycomb structure 315 is disposed inside the receiving cavity 313, and this structure is composed of densely arranged hexagonal or polygonal unit chambers. The molecular sieve is filled and evenly distributed in each unit chamber of the honeycomb structure 315. The honeycomb structure 315 can provide stable physical support and spatial separation for the molecular sieve, preventing the molecular sieve particles from shifting, settling, or locally accumulating due to vibration, gravity, or airflow impact during transportation, installation, or long-term use. Maintaining the uniform distribution of the molecular sieve within the receiving cavity 313 can ensure that the effective adsorption surface area of ​​the molecular sieve is maximized and remains stable over a long period of time, avoiding local adsorption saturation or blockage of the flow channels due to particle movement. The honeycomb structure 315, with its regular unit chambers and walls, significantly increases the contact area and contact time between the molecular sieve and the flowing gas. When an inert mixed gas containing trace amounts of water vapor enters the containment cavity 313 through the slit 314 and flows through the unit chambers of the honeycomb structure 315, the gas can more fully and uniformly contact the molecular sieve in each unit chamber, thereby significantly improving the molecular sieve's capture efficiency and adsorption rate for water vapor molecules. The honeycomb structure 315 itself has excellent mechanical load-bearing properties. Its porous and regularly arranged unit structure can effectively enhance the overall rigidity and compressive strength of the containment cavity 313. This ensures that the containment cavity 313 is not easily deformed when the frame spacer 310 bears the periodic stress transmitted by the first tempered glass plate 100 and the second tempered glass plate 200 due to thermal expansion and contraction through the first wing plate 320 and the second wing plate 330, or external installation stress, thus protecting the internal molecular sieve particles from mechanical compression damage.

[0041] In some embodiments of this utility model, the first wing plate 320 and the second wing plate 330 are provided with a plurality of hollow slots 321, which are linearly arranged along the length of the frame spacer 310. Specifically, in this embodiment, when the first tempered glass plate 100 or the second tempered glass plate 200 is displaced due to thermal expansion and contraction and pushes the first wing plate 320 or the second wing plate 330, the hollow slots 321 on the wing plate can preferentially guide the bending deformation to concentrate in the vicinity of the slots, causing the wing plate to produce a more uniform and controllable multi-segment bending deformation mode when under stress. This multi-segment bending can more efficiently disperse the displacement stress transmitted by the glass plate to a larger length range of the wing plate, avoiding excessive stress concentration at a single location such as the root of the connection between the wing plate and the frame spacer 310 or the middle of the wing plate, thereby significantly reducing the risk of plastic deformation or fatigue fracture of the wing plate itself due to stress concentration. This improves the overall sealing performance.

[0042] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 As shown, the frame spacer 310 comprises several profiles connected end-to-end, with a connecting structure 360 ​​between adjacent profiles. This structure allows for the design and assembly of frame spacers 310 in different shapes according to design requirements, improving practicality.

[0043] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 As shown, the connection structure 360 ​​includes a first connecting portion 361 and a second connecting portion 362; the first connecting portion 361 and the second connecting portion 362 are respectively disposed at both ends of the profile; the first connecting portion 361 is provided with a first inclined surface 363, and the second connecting portion 362 is provided with a second inclined surface 364; the inclination angle α of the first inclined surface 363 and the inclination angle β of the second inclined surface 364 are complementary angles. Specifically, in this embodiment, the connection structure 360 ​​between adjacent profiles includes a first connecting portion 361 and a second connecting portion 362 respectively disposed at both ends of the profile, the first connecting portion 361 is provided with a first inclined surface 363, the second connecting portion 362 is provided with a second inclined surface 364, and the inclination angle α of the first inclined surface 363 and the inclination angle β of the second inclined surface 364 are complementary angles, that is, the sum of α and β is 90 degrees. This geometric relationship allows the first inclined surface 363 of the first connecting part 361 to form a tight surface contact and automatically align with the second inclined surface 364 of the adjacent profile's second connecting part 362 when they are in contact. During the assembly of the frame spacer 310, the complementary angle design of the first inclined surface 363 and the second inclined surface 364 guides the profiles to align quickly and accurately, ensuring that the connection is straight and without misalignment. When the first tempered glass plate 100 and the second tempered glass plate 200 expand and contract due to temperature changes, the entire frame spacer 310 will be subjected to periodic expansion and contraction stress along its length. At this time, the first inclined surface 363 and the second inclined surface 364 at the profile connection can generate a slight relative sliding under stress. This sliding can effectively release the tensile or compressive stress accumulated at the profile connection interface, avoiding excessive stress concentration at local connection points that could lead to profile deformation, connection cracking, or overall warping of the frame spacer 310.

[0044] In some embodiments of this utility model, reference is made to Figure 4As shown, a tenon 365 is provided on the first inclined surface 363, and a mortise 366 is provided on the second inclined surface 364 corresponding to the tenon 365. Specifically, in this embodiment, the tenon 365 is provided on the first inclined surface 363, and the mortise 366 is correspondingly provided on the second inclined surface 364, forming a complementary concave-convex mating structure. When assembling the frame spacer 310, when the first inclined surface 363 of the first connecting part 361 and the second inclined surface 364 of the adjacent profile second connecting part 362 are in contact with each other, the tenon 365 can be simultaneously embedded into the mortise 366. The interlocking action of the tenon 365 and the mortise 366 can provide additional mechanical constraints on the basis of the inclined surface contact, effectively limiting any relative displacement or misalignment tendency of the profile connection in the direction perpendicular to the inclined surface, ensuring that the connection part maintains strict alignment when subjected to external vibration or installation stress.

[0045] In some embodiments of this utility model, reference is made to Figure 5 As shown, a connecting groove 367 is provided on the tenon 365, and a connecting head 368 is provided on the mortise 366. The connecting head 368 can be inserted into the connecting groove 367. Specifically, in this embodiment, through the design of this structure, the insertion and mating of the connecting head 368 and the connecting groove 367, based on the interlocking of the tenon 365 and the mortise 366, additionally establishes a secondary mechanical constraint perpendicular to the insertion direction of the tenon 365. This improves the structural strength of the connection.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
