Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum laminated glass, in particular to a novel composite sound-insulating vacuum laminated glass. Background Art
[0002] Vacuum laminated glass is a composite glass product with a vacuum cavity formed by sandwiching one or more layers of organic polymer interlayer between two layers of glass sheets, and undergoing special high-temperature pre-pressing or vacuuming. Common vacuum laminated glass mainly relies on the separation of the interlayer and the vacuum cavity to achieve the weakening of sound waves and reduce noise. However, in actual applications, the applicant has found that there are still the following deficiencies:
[0003] Since the vacuum laminated glass chamber is in a relative vacuum condition, both sides will be subjected to a large atmospheric pressure. In order to prevent the glass from breaking, there will be support parts in the vacuum chamber for support. When these support parts are used, they will also transmit sound waves, thus affecting the sound insulation effect of the glass. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0019] When in use, external light is transmitted into the room through the outdoor glass 3, and is isolated from the ultraviolet rays and blue light of the sunlight by the radiation-proof glass film 10, thereby playing a radiation-proof role. The composite anti-peep glass film 5 is applied to the indoor glass 1, so that the outdoor can be seen clearly from the indoor, but the indoor cannot be seen clearly from the outdoor, thereby protecting the privacy of the user and having a significant heat-insulating effect. The suction port of the vacuum chamber 7 is arranged in the hollow cavity 6 and is sealed by the silicone sealant 4, thereby slowing down the leakage rate of the vacuum chamber 7.
[0020] See also Figure 1 , Figure 2 and Figure 3 , further, the interlayer 9 is set to be double-layered, the interlayer 9 can be any one of PVB, SGP or EVA interlayer film, the thickness of the vacuum cavity 7 is 0.2mm, the indoor glass 1, the laminated glass 2 and the outdoor glass 3 are all tempered glass with a thickness of 5mm, and the thickness of the hollow cavity 6 is 5-6mm;

The three-layer tempered glass composite design has a high structural strength. The interlayer film 9 is in close contact with the tempered glass. After a collision, no glass shards will splash, which can improve the safety of the glass.
[0022] When the embodiment of the present application is in use: when sound waves pass through the vacuum laminated glass, the low-frequency sound wave vibrations will be absorbed by the laminated sheet 9, and the sound wave energy will be weakened by the vacuum cavity 7. Then the sound waves pass through the hollow cavity 6, and the hollow cavity 6 and the vacuum cavity 7 are combined to weaken the sound waves in the full frequency band, thereby greatly improving the sound insulation and noise reduction effect of the vacuum glass.
