Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulating glass technology, and in particular to a triple-glazed, double-cavity, UV-resistant insulating glass. Background Technology
[0002] With the continuous development of modern building technology and people's increasing demands for the quality of their living environment, insulated glass has been widely used in many fields such as construction, automobiles, and home furnishings due to its excellent heat insulation and sound insulation properties. Traditional insulated glass mainly focuses on reducing heat conduction and blocking external noise to improve indoor comfort and achieve energy-saving effects.
[0003] However, in practical use, the problems caused by ultraviolet radiation have gradually attracted people's attention. On the one hand, ultraviolet rays (especially the UVA and UVB bands) can penetrate ordinary glass, and prolonged exposure will cause indoor furniture, curtains, decorative materials, and various collectibles to age, fade, and deform more quickly, seriously affecting their aesthetics and lifespan. On the other hand, ultraviolet rays also pose potential threats to human health, such as causing sunburn, premature aging, and increasing the risk of skin cancer. This harm is particularly significant for people who are indoors for extended periods but are still indirectly affected by ultraviolet rays.
[0004] To address the issue of ultraviolet radiation, some insulated glass products with UV-resistant properties have emerged on the market, but they often have several shortcomings. Some products simply coat the glass surface with a common UV-resistant coating, which is insufficient in its UV protection. After a period of use, the coating is prone to peeling and aging, leading to a significant decrease in UV blocking efficiency. Other products, while using special glass materials to resist UV rays, suffer from inadequate structural design, failing to fully utilize the material's advantages and resulting in limited overall improvement in UV resistance.
[0005] Therefore, it is necessary to design a triple-glazed, double-cavity, UV-resistant insulated glass to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a triple-glazed, double-cavity UV-resistant insulated glass. This insulated glass, through its unique structural design and material selection, significantly improves the glass's UV resistance and overall performance.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A triple-glazed, double-cavity, UV-resistant insulated glass unit includes an outer glass layer, a middle glass layer on the front side of the outer glass layer, an inner glass layer on the front side of the middle glass layer, a first cavity between the outer glass layer and the middle glass layer, and a second cavity between the inner glass layer and the middle glass layer. Both the first and second cavities are filled with a mixed gas. The rear side of the outer glass layer is coated with a nano-UV-resistant coating, the front side of the inner glass layer is coated with a film layer, and the middle glass layer is made of cerium oxide glass.
[0009] Preferably, the mixed gas comprises 50%-70% argon and 20%-30% krypton.
[0010] Preferably, the nano-anti-UV coating is composed of nano-titanium dioxide and organic anti-UV polymer, and the nano-anti-UV coating is coated on the outer glass by magnetron sputtering.
[0011] Preferably, the cerium oxide has a mass fraction of 3%-5% in the intermediate glass.
[0012] Preferably, the coating layer includes a metal emitting layer, a dielectric layer, and a protective layer, wherein the metal emitting layer covers the inner glass layer, the dielectric layer is located in front of the metal emitting layer, and the protective layer is located in front of the dielectric layer.
[0013] Preferably, the outer glass layer and the middle glass layer, as well as the inner glass layer and the middle glass layer, are adhered together by an ultraviolet-resistant optical adhesive.
[0014] Compared with existing technologies, the advantages of this device are:
[0015] Compared with existing technologies, the triple-glazed, double-cavity UV-resistant insulated glass of this invention adopts a multi-directional synergistic UV-resistant design. Through the synergistic effect of multi-layer structure, multiple materials, and gases, it can significantly improve the UV blocking rate and more effectively protect indoor items and people from UV damage.
[0016] Compared with existing technologies, this device, through its three-glass, two-cavity structural layout, makes reasonable use of different chambers, different glass layers, and corresponding filling gases and coatings, achieving excellent UV resistance while still maintaining good heat insulation and sound insulation effects.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-3 A triple-glazed, double-cavity, UV-resistant insulated glass unit includes an outer glass layer 1, a middle glass layer 2 located in front of the outer glass layer 1, and an inner glass layer 3 located in front of the middle glass layer 2. A first cavity 6 is located between the outer glass layer 1 and the middle glass layer 2, and a second cavity 7 is located between the inner glass layer 3 and the middle glass layer 2. Both the first cavity 6 and the second cavity 7 are filled with a mixed gas, comprising 50%-70% argon and 20%-30% krypton. Argon, a commonly used inert gas, has excellent thermal insulation properties. Filling the cavity of the insulated glass unit with argon effectively reduces heat transfer between the indoor and outdoor spaces, lowering building energy consumption. The atomic structure and physicochemical properties of krypton make it resistant to ultraviolet radiation. It has unique scattering and absorption properties, and can work in synergy with other anti-UV structures to further enhance the overall UV blocking ability of the insulated glass. The outer glass 1 has a nano anti-UV coating 4 on the back side, and the inner glass 3 has a coating layer 5 on the front side. The middle glass 2 is made of glass containing cerium oxide. The mass fraction of cerium oxide in the middle glass 2 is 3%-5%. As a rare earth oxide, cerium oxide has a special electronic structure and optical properties, and has a significant absorption effect on ultraviolet rays. Within the range of 3%-5%, it can ensure that the middle glass 2 has good transparency and does not affect the overall light transmission performance of the glass, while maximizing the UV blocking advantage of cerium oxide.
[0023] The nano-UV-resistant coating 4 is composed of nano-titanium dioxide and an organic UV-resistant polymer. This coating is applied to the outer glass layer 1 using magnetron sputtering. The nano-titanium dioxide possesses unique photocatalytic properties and UV absorption and reflection characteristics. Its particle size is at the nanoscale, enabling it to form a uniform and dense protective layer on the glass surface. This significantly increases the contact area between UV rays and the coating, improving the absorption and reflection efficiency of UV rays. Simultaneously, the organic UV-resistant polymer exhibits good flexibility and adhesion. Its synergy with the nano-titanium dioxide not only enhances the overall stability of the coating but also further improves the UV blocking effect, effectively preventing UV rays from penetrating the outer glass layer 1 and entering the interior of the glass.
[0024] The coating layer 5 includes a metal emitting layer 8, a dielectric layer 9, and a protective layer 10. The metal emitting layer 8 covers the inner glass layer 3, the dielectric layer 9 is located in front of the metal emitting layer 8, and the protective layer 10 is located in front of the dielectric layer 9. The metal emitting layer 8 mainly plays the role of low radiation and reflection of infrared and residual ultraviolet rays. The dielectric layer 9 (such as silicon nitride) plays the role of adjusting optical performance, enhancing film adhesion, and improving the stability of the entire coating layer 5. The protective layer 10 (such as silicon dioxide) is used to protect the internal metal emitting layer 8 and dielectric layer 9 from the influence of external environmental factors.
[0025] The outer glass 1 and the middle glass 2, as well as the inner glass 3 and the middle glass 2, are all bonded together with an anti-ultraviolet optical adhesive.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
