Description

Technical Field

[0001] The utility model relates to a composite sound-insulating and heat-insulating toughened glass, belonging to the technical field of toughened glass. Background Technique

[0002] Toughened glass is actually a kind of prestressed glass. To improve the strength of ordinary glass, chemical or physical methods are usually used to make the glass into toughened glass, forming compressive stress on the glass surface. When the glass bears external forces, the surface stress is offset first, thus improving the bearing capacity and enhancing the wind pressure resistance, cold and heat resistance, impact resistance, etc. of the glass itself. The strength of toughened glass is several times that of ordinary glass and has bending resistance, and is widely used in high-rise building doors and windows, glass curtain walls, indoor partition glass, daylighting ceilings, sightseeing elevators, glass guardrails, etc.

[0003] For example, the publication number CN211397223U discloses a toughened glass, including an installation frame and toughened glass, characterized in that: the installation frame is surrounded by four frames, and each of the four frames is provided with an inwardly extending installation flange, the toughened glass is fixedly bonded to the four installation flanges, a sealing strip is slidably inserted into each frame, the four sides of the toughened glass are abutted against the corresponding sealing strips, and a plurality of installation holes are further opened on the back surface of the frame, and a pressing member for pressing the sealing strip against the toughened glass is provided on each installation hole. Through the above settings, after the toughened glass is bonded to the installation flange, it is pressed tightly by a plurality of sealing strips on the periphery, which can reduce the gap, improve the stability and sealing performance, and further improve the waterproof performance and extend the service life.

[0004] This toughened glass lacks a sound-insulating and heat-insulating structure, resulting in an unsatisfactory overall sound-insulating and heat-insulating effect. If the sound insulation is not good, external noises (such as traffic noise, construction noise, etc.) are easily transmitted into the room, affecting the quiet environment in the room, and may cause people living or working to feel irritable and uncomfortable. Poor heat insulation will cause the indoor temperature to be unstable, being hot in summer and cold in winter. To maintain a comfortable indoor temperature, more air conditioners or heating equipment may be needed, increasing energy consumption and usage costs.

[0005] Therefore, a composite sound-insulating and heat-insulating toughened glass is proposed. Content of the Utility Model

[0006] In view of this, the utility model provides a composite sound-insulating and heat-insulating toughened glass to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of the present utility model is realized as follows: A composite sound-insulating and heat-insulating tempered glass, comprising a tempered glass body, wherein the tempered glass body includes a Low-E glass base layer, a first functional layer, and a second functional layer. The first functional layer includes a PVB polyethylene interlayer film and a hollow glass layer, and the second functional layer includes a nano-vacuum heat-insulating coating and a sound-insulating film.

[0008] Further preferably, the first functional layer is disposed on the outer surface of the Low-E glass base layer, and the second functional layer is disposed on the outer surface of the first functional layer.

[0009] Further preferably, the PVB polyethylene interlayer film is disposed on the outer surface of the Low-E glass base layer, and the hollow glass layer is disposed on the outer surface of the PVB polyethylene interlayer film.

[0010] Further preferably, the nano-vacuum heat-insulating coating is disposed on the outer surface of the hollow glass layer, and the sound-insulating film is disposed on the outer surface of the nano-vacuum heat-insulating coating.

[0011] Further preferably, the PVB polyethylene interlayer film and the hollow glass layer have the same thickness, and the thickness is 2.3 mm - 2.5 mm.

[0012] Further preferably, the nano-vacuum heat-insulating coating and the sound-insulating film have the same thickness, and the thickness is 0.7 mm - 0.9 mm.

[0013] Due to the adoption of the above technical solution in the embodiment of the present utility model, it has the following advantages:

[0014] First, the present utility model provides a first functional layer including a PVB polyethylene interlayer film and a hollow glass layer. Among them, the PVB polyethylene interlayer film can convert sound wave vibration into heat energy, effectively isolate the transmission of sound waves, improve the sound insulation performance of the tempered glass body, and at the same time, it can also prevent the fragments generated after the tempered glass body is broken from flying, improving the use safety. The hollow glass layer can prevent the direct conduction of heat, significantly improve the heat insulation performance of the tempered glass body, and can hinder the propagation of sound waves, further enhancing the sound insulation effect of the tempered glass body.

[0015] Second, the present utility model provides a second functional layer including a nano-vacuum heat-insulating coating and a sound-insulating film. Among them, the nano-vacuum heat-insulating coating almost completely eliminates heat conduction and convection, provides excellent heat insulation performance for the tempered glass body, and also has high weather resistance and chemical stability, and can maintain the heat insulation effect for a long time. The sound-insulating film can effectively absorb and reflect sound waves, further enhancing the sound insulation performance of the tempered glass body, and at the same time, it will not affect the light transmittance of the tempered glass body.

[0016] III. By providing a Low-E glass substrate, the present utility model can effectively reduce the solar radiation passing through the tempered glass body, thereby lowering the indoor temperature, saving air-conditioning costs. At the same time, due to its high density and thickness, it can also provide a certain degree of sound insulation effect.
