Description

Technical Field

[0001] This utility model relates to the field of glass products, specifically to a warm-edge TPS glass. Background Technology

[0002] Traditional insulating glass units often use aluminum spacers, which have several drawbacks, such as significant thermal bridging leading to heat loss at the edges, poor sealing resulting in an internal argon gas leakage rate greater than 0.3%, and low shear strength. To address some of these shortcomings, [the following is an example of a design with authorization announcement number CN 214035351]. According to a Chinese patent, a multi-cavity TPS warm-edge insulated glass unit is proposed, comprising a frame, with glass disposed on the inner surface of the frame, a bulletproof and sound-insulating layer disposed inside the glass, a first sealant and a second insulating sealant disposed on the inner surface of the glass, with the first sealant located above the second insulating sealant, a second thermoplastic spacer disposed on the outer surface of the upper end of the second insulating sealant, a shock-absorbing mechanism disposed on the outer surface of the frame, a fixing and positioning block disposed at the rear end of the shock-absorbing mechanism, a spring disposed on one side of the outer surface of the fixing and positioning block, a baffle disposed on one end of the outer surface of the spring, a sponge disposed on one side of the outer surface of the baffle, a silicone film disposed on the inner surface of the fixing and positioning block, and a first thermoplastic spacer disposed on the outer surface of the glass.

[0003] It demonstrates a solution that avoids the aforementioned defects by not using traditional aluminum spacers. However, this traditional structure has not been modified for the corners of the entire glass product, resulting in the continued presence of the aforementioned problems at the corners and affecting its service life. Utility Model Content

[0004] Therefore, this utility model provides a warm-edge TPS glass, which solves the problem of insufficient strength at the corners of current TPS glass.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A warm-edge TPS glass includes two parallel glass substrates and TPS spacers disposed on the peripheral edges of the glass substrates. The ends of each TPS spacer are co-extruded and embedded in a rigid skeleton. Dovetail joints are provided at the joints of adjacent TPS spacers for interlocking connection. An elastic buffer pad is embedded between the TPS spacer at the dovetail joint and each glass substrate. A silicone structural adhesive layer is provided at the joint between each TPS spacer and each glass substrate.

[0007] Preferably, the rigid frame is a two-piece structure, which is respectively embedded on both sides of the TPS spacer near the surface of each glass substrate.

[0008] Preferably, the elastic buffer pad is an L-shaped EPDM or silicone pad.

[0009] Preferably, the elastic buffer pad has a thickness of 0.2-0.5 mm and a compression ratio of ≥30%.

[0010] Preferably, the rigid skeleton is glass fiber reinforced polypropylene or carbon fiber.

[0011] Preferably, the surface of the TPS spacer is coated with a modified silicone coating.

[0012] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0013] This technical solution addresses the structural design of TPS glass corners by embedding a rigid skeleton into the ends of traditional TPS spacers through co-extrusion to increase the material strength at the corner joints, forming a "rigid-flexible composite" structure. This enhances the corners' shear resistance, disperses stress concentration, and prevents deformation and breakage caused by temperature differences or wind pressure. Furthermore, the ends of the TPS spacers are designed with a dovetail tenon joint, enabling precise splicing of adjacent TPS strips without the need for additional corner fittings or welding. This increases the contact area and avoids the risk of interface cracking associated with traditional bending processes. During installation, a hot-pressing process achieves seamless fusion. This structure solves the problems of low shear strength, poor sealing, and significant thermal bridging effects inherent in traditional corner structures. Attached Figure Description

[0017] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Example

[0019] refer to Figure 1 and Figure 2A warm-edge TPS glass includes two parallel glass substrates 1 and TPS spacers 2, i.e. thermoplastic spacers, located on the periphery of the glass substrates 1. These spacers are commonly used materials on the market, integrally extruded from butyl rubber and molecular sieves, with a thermal conductivity ≤0.3W / (m·K), and are directly bonded to the inner surface of the glass substrates 1. A new material is introduced for structural redesign: a rigid skeleton 3 is co-extruded and embedded at the ends of each TPS spacer 2. The rigid skeleton 3 is a high-strength, low-thermal-conductivity composite material such as glass fiber reinforced polypropylene or carbon fiber, which can significantly improve shear strength (from 0.8-1.2MPa of traditional TPS to ≥2.5MPa).

[0020] On this basis, dovetail tenon structures 21 are provided at the connection of adjacent TPS spacers 2 to interlock. The dovetail tenon structures 21 achieve seamless splicing through hot pressing process, forming structural interlocking, reducing the risk of cracking caused by traditional external corner insertion or welding processes, and making the appearance more beautiful.

[0021] Accordingly, the rigid frame 3 is a two-piece structure, which is respectively embedded on both sides of the TPS spacer 2 near the surface of each glass substrate 1. That is, the rigid frame 3 is placed in the design position of the dovetail structure 21 to ensure the structural rigidity of the connection position and further improve the structural strength.

[0022] In this embodiment, a conventional silicone structural adhesive layer 4 is provided at the joint between each TPS spacer 2 and each glass substrate 1 for fixing. A continuous sealing layer is formed by chemical bonding, which has a high elastic recovery rate and ensures that the annual argon leakage rate is ≤0.05%.

[0023] Structurally, an elastic buffer pad 5 is embedded between the TPS spacer 2 at the dovetail tenon structure 21 and each glass substrate 1. The elastic buffer pad 5 is an L-shaped EPDM or silicone pad with a thickness of 0.2-0.5mm and a compression rate of ≥30%. It can block the water vapor penetration path and absorb the stress at the corners to a certain extent, preventing cracking.

[0024] This technical solution addresses the structural design of TPS glass corners by embedding a rigid skeleton 3 into the ends of the traditional TPS spacer 2 through co-extrusion to increase the material strength at the corner joints, forming a "rigid-flexible composite" structure. This enhances the corner's shear resistance, disperses stress concentration, and prevents deformation and breakage caused by temperature differences or wind pressure. Furthermore, the ends of the TPS spacer 2 are designed with a dovetail tenon structure 21 for precise splicing of adjacent TPS strips, eliminating the need for additional corner joints or welding. This increases the contact area and avoids the risk of interface cracking associated with traditional bending processes. During installation, a hot-pressing process is used to achieve seamless fusion. This structure solves the problems of low shear strength, poor sealing, and significant thermal bridging effects in traditional corner structures.

[0025] After the above structure is roughly installed, a modified silicone coating 6 is applied to the surface of the TPS spacer 2. The modified silicone coating 6 is a microcapsule coating that automatically releases a repair agent to fill cracks when they appear, improving long-term sealing durability. It also works with the silicone structural adhesive layer 4 and the elastic buffer pad 5 to form a three-level sealing structure.

[0026] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
