Description

Technical Field

[0001] This utility model relates to the field of glass technology, and in particular to an insulated glass with good sound and heat insulation effects. Background Technology

[0002] Insulating glass is usually composed of two or more layers of flat glass. The glass panes are bonded and sealed to the sealing strips and frames (such as aluminum alloy frames or glass strips) with a high-strength, airtight composite adhesive around the perimeter. The glass panes are then bonded and sealed with the sealing strips and frames (such as aluminum alloy frames or glass strips) through processes such as gluing, welding or fusion. The finished glass and frame are then installed on the window or windowsill.

[0003] However, the sound insulation performance of existing tempered insulated glass is usually significantly weaker than its heat insulation performance. At the same time, the dry air filled in the insulated layer will expand or contract due to changes in temperature or air pressure, resulting in internal air pressure imbalance, which may cause deformation of the glass panel or even structural damage, reducing the sound insulation and heat insulation effect of the glass panel. To address these issues, we propose an insulated glass with good sound insulation and heat insulation performance. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the internal pressure of the hollow layer in the existing technology is easily affected by fluctuations, which can easily cause deformation or even breakage of the glass surface. The invention proposes a hollow glass with good sound insulation and heat insulation effects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A type of insulated glass with good sound and heat insulation properties includes a frame and a limiting structure formed on the inner side of the frame, wherein the limiting structure is filled with a sealing element; at least three sets of glass are disposed on the limiting structure, wherein a first hollow cavity and a second hollow cavity are formed between two adjacent sets of glass, an inert gas and a vacuum are respectively disposed in the first hollow cavity and the second hollow cavity, and a first functional coating is disposed on the glass surface forming the first hollow cavity and the second hollow cavity; a second functional coating is disposed on the outer side of one set of glass; and a third functional coating is disposed on the outer side of another set of glass.

[0007] To improve the sealing effect of the hollow cavity, preferably, the limiting structure includes a limiting plate fixedly connected to the inner side of the frame, an installation groove is formed between two adjacent sets of limiting plates, the edge of the glass is set in the installation groove, and the seal is filled in the installation groove.

[0008] Furthermore, the sealing element comprises a butyl rubber layer and a silicone structural adhesive layer, with the butyl rubber layer disposed on the glass and the silicone structural adhesive layer disposed on top of the butyl rubber layer.

[0009] To improve the heat insulation effect of the first glass, preferably, the first functional coating is a silver-based nanofilm or a low-emissivity metal film.

[0010] To further improve the sound insulation and heat insulation of the hollow cavity, the second functional coating is an ATO nanoparticle layer.

[0011] To improve the sound insulation effect of the third glass, preferably, the third functional coating is a PVB interlayer film or a magnetic absorbing film.

[0012] Compared with the prior art, this utility model provides a double-glazed glass with good sound and heat insulation effects, and has the following beneficial effects:

[0013] 1. The sound and heat insulation effect of the insulated glass can reduce or block the infrared rays generated by the sun through the first functional coating. It can also work in conjunction with the argon gas in the first hollow cavity to reduce the heat transfer between the first glass and the second glass, thereby improving the heat insulation effect of the device.

[0014] 2. This soundproof and heat-insulating insulated glass, through the use of a butyl sealant layer, can preferentially isolate the glass edge from direct contact with the environment. At the same time, it can also absorb the shear strain caused by the difference in thermal expansion between the glass and the frame, avoiding cracking caused by stress concentration in the silicone structural sealant layer. The outer layer of the silicone structural sealant layer can block the degradation effect of ultraviolet rays on the butyl sealant layer, preventing the environment inside the hollow cavity from expanding or contracting due to changes in temperature or air pressure, and ensuring that the internal air pressure is in a balanced state.

[0015] 3. This soundproof and heat-insulating insulating glass, when used in conjunction with the second hollow cavity through a third functional coating, can effectively reduce the propagation of noise and improve the sound insulation effect of the device.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technology. This utility model can reduce the heat transfer between the first glass and the second glass, thereby improving the heat insulation effect of the device. It can also effectively reduce the propagation of noise, improve the sound insulation effect of the device, and use sealing elements to prevent the environment inside the hollow cavity from expanding or contracting due to changes in temperature or air pressure, ensuring that the internal air pressure is in a balanced state.

[0026] Insulating glass is usually composed of two or more layers of flat glass. The glass panes are bonded and sealed to the sealing strips and frames (such as aluminum alloy frames 4 or glass strips) with a high-strength, high-airtightness composite adhesive around the perimeter. The glass panes are then bonded and sealed to the sealing strips and frames (such as aluminum alloy frames 4 or glass strips) through processes such as gluing, welding or fusion. The finished glass and frame 4 are then installed on the window or windowsill. The device uses a stainless steel frame 4 to support and install the flat glass.

[0027] Example:

[0028] Reference Figures 1-4 A type of insulated glass with good sound and heat insulation properties is provided. A limiting structure is provided on the inner side of a frame 4, and the limiting structure is filled with a sealant. Three sets of glass are provided on the limiting structure: a first glass 1, a second glass 2, and a third glass 3. Other numbers of glass can be provided as needed. The device uses three layers of equidistantly arranged glass. The limiting structure includes at least two sets of limiting plates 5 fixedly connected to the inner side of the frame 4. At least three sets of mounting grooves are formed between the limiting plates 5 for installing the flat glass. The mounting grooves are filled with sealants to resist stress generated by the thermal expansion of the coating. The first glass 1 is fixedly connected in one of the mounting grooves. The outer surface of the first glass 1 is provided with a first... The first functional coating 101 is mainly used to reduce or block infrared radiation generated by the sun. The first functional coating 101 is a silver-based nanofilm or a low-emissivity metal film. When using a low-emissivity metal film, the silver-based nanofilm prepared by magnetron sputtering can reflect ≥90% of infrared radiation (wavelength 780-2500nm), significantly reducing heat conduction. The low-emissivity metal film is a composite structure composed of multiple metal oxides, achieving a total solar energy rejection rate of 40%-60%. When using a silver-based nanofilm, its coating can maintain ≥75% visible light transmittance, while the low-emissivity metal film achieves a transmittance of ≥85% by optimizing the thickness, meeting the needs of natural lighting.

[0029] Secondly, a second glass 2 is fixedly connected within the mounting groove. A second functional coating 201 is provided on the side of the second glass 2. The first glass 1 and the second glass 2 are arranged parallel to each other to form a first hollow cavity. The first hollow cavity is filled with an inert gas, which can be nitrogen, helium, or argon. When the first functional coating 101 is used in conjunction with the argon gas in the first hollow cavity, its thermal conductivity is only 0.016 W / m·K, and the overall heat transfer coefficient can be reduced to ≤1.2 W / (m²·K), thereby reducing the heat energy between the first glass 1 and the second glass 2. The second functional coating 201 is an ATO nanoparticle layer. The ATO nanoparticle layer is set on the outer surface of the second glass 2. It is mainly used to enhance the energy-saving performance and environmental adaptability of the glass. The ATO nanoparticle layer contains antimony-doped tin oxide (ATO) nanoparticles (particle size ≤50nm) that can selectively block the near-infrared band (800-2500nm), with an infrared reflectivity >80% and an impact on visible light transmittance ≤5%. It also has high temperature resistance (≤700℃) and acid and alkali stability, making it suitable for the installation and use environment of insulated glass.

[0030] Thirdly, a third glass 3 is fixedly connected in the mounting groove. A third functional coating 301 is provided on the outer surface of the third glass 3. The third glass 3 and the second glass 2 are arranged parallel to form a second hollow cavity. The second hollow cavity is in a vacuum state. The third functional coating 301 is a PVB interlayer film or a magnetic absorbing film. When using a PVB interlayer film, the viscoelastic damping characteristics of polyvinyl butyral weaken the transmission of sound wave energy in the 1000-2000Hz frequency band, increasing the sound insulation to more than 35dB. In addition, its light transmittance is ≥85% and its tensile strength is ≥20MPa, thereby improving the sound insulation effect of the device. When using a magnetic absorbing film, the ferrite magnetic particles (content 10%-15%) in the magnetic absorbing film convert the 500-2000Hz sound waves into heat energy, with a sound absorption coefficient ≥0.8, thus reducing noise simultaneously. In addition, the design of the second hollow cavity in a vacuum state can also effectively reduce the propagation effect of noise.

[0031] In the above scheme, the first functional coating 101 can reduce or block infrared rays generated by the sun, and can also be used in conjunction with argon gas in the first hollow cavity to reduce heat transfer between the first glass 1 and the second glass 2, thereby improving the heat insulation effect of the device. The sealing element consists of a butyl rubber layer 6 and a silicone structural adhesive layer 7. The butyl rubber layer 6 directly contacts the glass and the mounting groove. The silicone structural adhesive layer 7 is covered by the butyl rubber layer 6 to form a protective layer. The butyl rubber layer 6 can preferentially isolate the glass edge from direct contact with the environment, and can also absorb... The shear strain caused by the thermal expansion difference between the glass and the frame 4 avoids cracking caused by stress concentration in the silicone structural adhesive layer 7. The outer layer of the silicone structural adhesive layer 7 can block the degradation of the butyl adhesive layer 6 by ultraviolet rays, preventing the environment inside the hollow cavity from expanding or contracting due to temperature or air pressure changes, and ensuring that the internal air pressure is in a balanced state. By setting the ATO nanoparticle layer on the outer surface of the second glass 2 and on the side of the first glass 1 and the third glass 3 facing the hollow cavity, it is mainly used to enhance the energy-saving performance and environmental adaptability of the glass, making it suitable for the installation and use environment of the insulated glass.

[0032] 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.
