Description

Technical Field

[0001] This utility model relates to the field of glass technology, and in particular to insulated glass. Background Technology

[0002] With the development of technology, smart glass, especially smart glass, has become an important development direction for architectural glass. Smart glass can freely switch between transparent and frosted states through electro-optic effects, providing excellent privacy protection and energy-saving effects. Meanwhile, in the field of glass manufacturing technology, laminated glass is a common production process. By sandwiching a film between two layers of glass, the safety and sound insulation performance of the glass can be improved. Furthermore, in the field of architectural design technology, the design of building curtain walls is constantly evolving, requiring not only aesthetics but also good heat insulation, sound insulation, and energy-saving performance. Existing smart glass typically uses a liquid crystal film (switching film) sandwiched between two layers of glass, adjusting the transparency of the glass by controlling the on / off state of the current. This type of smart glass has good dimming and color-changing effects, but with prolonged use, it will be affected by ultraviolet aging, causing the color to yellow and discolor, affecting its aesthetics and usability.

[0003] For example, CN216052546U, published on March 15, 2022, discloses an energy-saving electrochromic smart glass, belonging to the glass industry. It includes a first substrate, a dimming layer, a second substrate, and a third substrate arranged sequentially. Sealant is provided at both ends between the second and third substrates, and a hollow cavity is formed between the three substrates. A LOW-E layer is provided within the hollow cavity on the side closest to the second substrate. The glass disclosed above is prone to discoloration under prolonged exposure to light, resulting in low practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a more practical insulated glass unit. This invention uses an anti-aging glass layer to prevent the dimming glass from aging after long-term exposure to ultraviolet radiation, thus ensuring the normal use of the dimming glass layer and making it more practical.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: insulated glass, including an anti-aging glass layer, an insulated argon gas layer and a dimming glass layer, wherein the insulated argon gas layer is disposed between the anti-aging glass layer and the dimming glass layer.

[0006] The anti-aging glass layer includes a first glass substrate, a first film layer, a second glass substrate, and a first coating layer, which are arranged sequentially. The hollow argon layer is disposed on one side of the first coating layer.

[0007] The dimming glass layer includes a third glass substrate, a second coating layer, a second film layer, a dimming and color-changing layer, a third film layer, and a fourth glass substrate. The third glass substrate, the second coating layer, the second film layer, the dimming and color-changing layer, the third film layer, and the fourth glass substrate are arranged sequentially, and the third glass substrate is disposed on the side close to the hollow argon gas layer.

[0008] The first coating layer is a high-performance LOW-E film layer, and the second coating layer is a high-transmittance, colorless, neutral, high-performance LOW-E film layer.

[0009] The first glass substrate is located outdoors, and the fourth glass substrate is located indoors.

[0010] The first film layer is a PVB film layer.

[0011] The beneficial effects of this utility model are:

[0012] The anti-aging glass layer protects the dimming glass layer, increasing the overall sun-shading performance of the glass and preventing discoloration of the dimming glass layer caused by long-term direct exposure to ultraviolet rays, thus ensuring the normal use of the dimming glass layer and making it more practical. The heat insulation and sound insulation performance of the entire insulated glass is achieved through the hollow argon gas layer between the anti-aging glass layer and the dimming glass layer.

[0013] By setting the first and second coating layers, the insulated glass not only has sound and heat insulation functions but also better sun shading function; the setting of the first, second, and third film layers prevents glass fragments from scattering when the entire glass breaks, making it more practical.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] like Figure 1 As shown, the insulated glass includes an anti-aging glass layer 100, an insulated argon layer 5, and a dimming glass layer 200. The insulated argon layer 5 is disposed between the anti-aging glass layer 100 and the dimming glass layer 200. The anti-aging glass layer 100 blocks ultraviolet light and prevents the dimming film of the dimming glass layer 200 from yellowing and discoloring, thus reducing the shading effect.

[0019] In use, the anti-aging glass layer 100 is installed outdoors, and the dimming glass layer 200 is installed indoors. The anti-aging glass layer 100 protects the dimming glass layer 200, increasing the overall sun-shading performance of the glass and preventing discoloration of the dimming glass layer 200 caused by long-term direct ultraviolet radiation, thus ensuring the normal use of the dimming glass layer 200 and making it more practical. The heat insulation and sound insulation performance of the entire insulating glass is achieved through the hollow argon gas layer 5 between the anti-aging glass layer 100 and the dimming glass layer 200.

[0020] The anti-aging glass layer 100 includes a first glass substrate 1, a first film layer 2, a second glass substrate 3, and a first coating layer 4. The first glass substrate 1, the first film layer 2, the second glass substrate 3, and the first coating layer 4 are arranged sequentially. A hollow argon gas layer 5 is disposed on one side of the first coating layer 4. The first film layer 2 between the first glass substrate 1 and the second glass substrate 3 enables the adhesion of fragments when the anti-aging glass layer 10 breaks, preventing glass from splashing. Specifically, the first glass substrate 1 and the second glass substrate 3 are cut, edge-ground, and semi-tempered. A LOW-E film is deposited on one side of the second glass substrate 3 using a vacuum magnetron sputtering coating equipment. The anti-aging glass layer 100 is formed by sandwiching the first glass substrate 1, the first film layer 2, the second glass substrate 3, and the first coating layer 4 using a laminated glass process.

[0021] The dimming glass layer 200 includes a third glass substrate 6, a second coating layer 7, a second film layer 8, a dimming and color-changing layer 9, a third film layer 10, and a fourth glass substrate 11. These components are arranged sequentially. The third glass substrate 6 is positioned near the hollow argon layer 5. Dimming and color-changing of the glass are achieved by controlling the current flowing through the dimming and color-changing layer 9. The second film layer 8 and the third film layer 10 prevent glass fragments from scattering when the dimming and color-changing layer 200 breaks. The second coating layer 7 provides sun protection for the dimming glass layer 200. Specifically, when no power is applied, the glass has a frosted finish, protecting privacy. This design solves the problem of limited functionality in existing dimming glass and enhances privacy protection. It also supports remote control, enabling remote network control and voice control via an app. This design solves the problem of insufficient control flexibility in existing smart dimming glass. The smart dimming glass also has projection capabilities, allowing it to be used as a projection screen, replacing a regular screen. This design enhances the functionality of the smart dimming glass.

[0022] Conductive busbars are welded to one or both sides of the dimming and color-changing film of the dimming and color-changing layer 9. The busbars are welded with wire connectors. Two additional welding heads can be welded for backup. The dimming and color-changing film should be 5mm smaller than the glass substrate and the film. It is produced by edge-fitting process with a distance of 5mm from the edge of the glass to prevent the risk of delamination after lamination. The third glass substrate 6 and the fourth glass substrate 11 are both semi-tempered. The third glass substrate 6, the second coating layer 7, the second film layer 8, the dimming and color-changing layer 9, the third film layer 10 and the fourth glass substrate 11 are laminated to form the dimming glass layer 200.

[0023] Specifically, the first coating layer 4 is a high-performance LOW-E film layer, and the second coating layer 7 is a high-transmittance colorless neutral high-performance LOW-E film layer. The surface color of the second coating layer 7 and the glass surface color are almost the same as those of the white wave, so it does not affect the color of the color-changing glass or the appearance color of the glass. Both the first coating layer 4 and the second coating layer 7 are coated by vacuum magnetron sputtering equipment.

[0024] The first glass substrate 1 is installed outdoors, and the fourth glass substrate 11 is installed indoors, thereby ensuring that the insulated glass can work normally.

[0025] The first film layer 2 is a PVB film layer. PVB film has a smooth surface and good tensile strength and elongation at break, thus ensuring that the glass does not easily scatter when it breaks. Specifically, the materials of the second film layer 8 and the third film layer 10 are either PVB or EVA. In this embodiment, the second film layer 8 is a PVB layer and the third film layer 10 is an EVA layer.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
