Embodiment 1
[0045] Embodiment 1: A kind of sound-absorbing and insulating board, such as figure 1 As shown, the sound absorbing part 2 and the sound insulating part 1 are included, and the sound absorbing part 2 and the sound insulating part 1 can be separated from each other and independently arranged, and can also be connected to each other. Wherein, the sound insulation part 1 is pasted on the wall.
[0046] Such as figure 1 and 2 As shown, the sound insulation part 1 and the sound absorption part 2 are separated by a detachable baffle 6, and the baffle 6 in this embodiment adopts barbed wire. The sound insulation part 1 is a cavity 9, and the sound absorption part 2 is compressed and filled with a fluffy filler 4. In order to reduce the situation that the fluffy filler 4 looses and falls off, the fluffy filler 4 is covered with a non-woven fabric 5 . The non-woven fabric 5 binds the fluffy filler 4 tightly, and the two sides of the non-woven fabric 5 are folded toward the side of ...
Embodiment 2
[0058] The methods for disassembling and assembling the baffle plate 6, and compressing and loosening the non-woven fabric 5 are as follows:
[0059] S1: Prefabricated corrugated board 3, and side panels 7 are vertically connected to both sides of corrugated board 3;
[0060] S2: Fill the groove of the corrugated board 3 with the fluffy filler 4 coated with the non-woven fabric 5, leave the non-woven fabric 5 for a length, and the length ranges from 5cm to 10cm;
[0061] S3: cutting the non-woven fabric 5 into strips;
[0062] S4: Fold the strip part of the non-woven fabric 5 into a "Z" shape, and compact the non-woven fabric 5;
[0063] S5: Spray water on the compacted non-woven fabric 5 so that the water-sprayed non-woven fabric 5 faces away from the ground;
[0064] S6: When the water has not completely evaporated, place the baffle 6 on the surface of the non-woven fabric 5;
[0065] S7: press the folded plate 8 on both sides of the baffle plate 6, and fix the folded pla...

Abstract
The invention discloses a sound absorption and insulation board and a manufacturing method thereof. According to the key points of the technical scheme of the sound absorption and insulation board, the sound absorption and insulation board comprises a sound insulation part and a sound absorption part. A baffle is arranged between the sound insulation part and the sound absorption part, the baffleis of a detachable structure, the sound insulation part is internally filled with a gas medium, and the sound absorption part is internally filled with a solid medium. Different media are arranged inthe sound insulation part and the sound absorption part correspondingly, the media of the sound insulation part and the sound absorption part are mutually integrated after the two spaces communicate with each other, or the medium in one space extends into the adjacent space, so that the passed distance in the medium transmitting process is longer in the sound wave transmitting process, more energyis consumed at the different media, and a higher sound insulation effect is achieved.
Description
technical field [0001] The invention relates to a sound-insulating board, in particular to a sound-absorbing and insulating board and a manufacturing method thereof. Background technique [0002] Sound insulation board is a common building material used to block noise. Usually, a porous material with pores is added to the conventional board to block the transmission of sound waves. [0003] At present, the Chinese patent with the publication number CN106782482A discloses a composite sound-absorbing and sound-insulating panel, which has a multi-layer structure, and an air layer is provided between the honeycomb sandwich layers of the two panels to avoid the respective barrier troughs. [0004] This kind of sound-absorbing and insulating panels is common in the market, but the sound insulation strength of this kind of sound-absorbing and insulating panels is fixed, and the noise encountered in daily life is an uncontrollable factor, which varies from time to time. , the noise...
