DETAILED DESCRIPTION

[0036] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. In order to further understand the features, technical means and specific purposes achieved by the present application, the advantages and spirits of the present application, the following detailed description of the present application is obtained by combining the drawings and specific embodiments.

[0037] It should be understood that when a component is referred to as being "on" or "disposed on" another component, it can be directly on the other component or intervening components can also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components can also be present. The terms "vertical", "horizontal", "front", "back", and similar terms as used herein are for illustrative purposes only and are not meant to be limiting.

[0038] Please refer to the drawings, the sound-absorbing wall cloth 1 of the utility model, the thickness is 0.5~3mm, including sound-absorbing base material layer 2, sound-absorbing base material layer 2 is provided with local three-dimensional pattern layer 3 on it;

[0039] It further includes waterproof film layer 4, and the waterproof film layer 4 is arranged on the surface of the sound-absorbing base material layer 2 and the local three-dimensional pattern layer 3.

[0040] The thickness of the sound-absorbing wall cloth 1 is in the range of 0.5~3mm, so that good sound-absorbing effect can be achieved. The sound-absorbing base material layer 2 can achieve sound-absorbing effect, the local three-dimensional pattern layer 3 can achieve good decorative effect, and the waterproof film layer 4 is breathable and waterproof, so that good waterproof effect is achieved during use of the wall cloth, and in addition, the sound-absorbing wall cloth 1 is convenient to maintain.

[0041] Further, in one embodiment, the thickness of the sound-absorbing base material layer 2 is 0.2~1.0mm, the area density is 50~350g / m 2 , the porosity is 20%~30%, and the average sound-absorbing coefficient is 0.4~0.8. The sound-absorbing material refers to a material with an average sound-absorbing coefficient greater than 0.2. The frequency range of human speech mainly concentrates on 500Hz~2000Hz. The sound-absorbing base material layer 2 of the present application has good sound-absorbing effect on sound in this frequency range under the thickness and area density.

[0042] In addition, it should be noted that when the thickness and area density of the sound-absorbing base material layer 2 are increased without considering the sound-absorbing frequency, the average sound-absorbing coefficient of the sound-absorbing base material layer 2 does not increase significantly. Therefore, if the sound-absorbing effect of the sound-absorbing wall cloth 1 needs to be further improved, other methods need to be used.

[0043] The sound-absorbing base material layer 2 is one of a non-woven fabric layer or a plain weave cloth layer. The sound-absorbing base material layer 2 uses non-woven fabric and plain weave cloth as the bottom layer of the wall cloth. The non-woven fabric is made of polyester fiber, acrylic fiber, glass fiber, etc., and has a large number of micropores and gaps uniformly distributed inside, and the internal pores of the non-woven fabric are interconnected, which is conducive to the entry of sound waves, so the sound energy absorption effect is good. In addition, the use of glass fiber as the material can achieve good flame retardation effect.

[0044] The partial stereoscopic pattern layer 3 is a stereoscopic paste pattern layer and / or a PVC foaming paste layer, that is, a partial stereoscopic effect pattern layer, and the coverage of the partial stereoscopic pattern layer 3 is 5-15%, and the thickness is 0.5-1 mm.

[0045] In order to maintain good sound absorption effect, the surface of the sound absorption substrate layer 2 is fluffy, and the ordinary ink is directly printed.

[0046] The coverage of the partial stereoscopic pattern layer 3 can play the good sound absorption effect of the sound absorption substrate layer 2, and it is necessary to note that the layer structure formed by the PVC foaming adopts the foaming agent (such as AC foaming agent) which expands to form pores under heat, and the formed pores are mainly single bubbles and closed spaces, which are difficult to play the sound absorption effect; and the surface of the stereoscopic paste is dense, and the sound absorption effect on the sound wave is weak.

[0047] Further, in one of the embodiments, the waterproof film layer 4 is a polytetrafluoroethylene protective layer with a micropore diameter of 0.1-20 μm. The polytetrafluoroethylene protective layer with the micropore diameter has the effect of waterproof and breathable, which can facilitate the cleaning of the sound absorption wall cloth 1, and since the surface of the polytetrafluoroethylene has micropores, it will not block the sound wave from entering the inside of the sound absorption wall cloth 1.

[0048] The sound absorption wall cloth 1 further comprises a textile cloth layer 5, and the textile cloth layer 5 is arranged on the sound absorption substrate layer 2 through the adhesive. The textile cloth layer 5 is a plain cotton cloth layer. By arranging the textile cloth layer 5, on the one hand, the overall thickness of the sound absorption wall cloth 1 is increased to play a good sound absorption effect; on the other hand, the surface of the textile cloth layer 5 has delicate textile texture, and the texture can be increased to achieve a good decorative effect.

[0049] A sound absorption decorative structure comprises a wall surface 6;

[0050] Further comprising a waterproof coating layer 7 arranged on the wall surface 6; and a sound absorption enhancement layer 8 fixedly arranged on the side of the waterproof coating layer 7 away from the wall surface 6;

[0051] Further comprising a frame-shaped adhesive layer 9 comprising an adhesive frame arranged around the sound absorption enhancement layer 8 and a plurality of adhesive reinforcing strips inside the adhesive frame;

[0052] Further comprising a sound absorption wall cloth 1 arranged on the sound absorption enhancement layer 8.

[0053] The sound absorption effect of the structure can be further improved by arranging the sound absorption enhancement layer 8. In addition, by arranging the frame-shaped adhesive layer 9, on the one hand, the adhesive can be reduced in the fixing of the sound absorption enhancement layer 8 and the sound absorption wall cloth 1 layer, and the effect of the sound absorption enhancement layer 8 can be weakened; on the other hand, by arranging the frame-shaped adhesive layer 9, the sound absorption wall cloth 1 and the sound absorption enhancement layer 8 are not glued at all positions, and when the sound absorption wall cloth 1 needs to be disassembled, it is more convenient. Other adhesives are common adhesives, and the amount of adhesives is relatively small, and full coating can be used; in the frequency range of 500Hz~2000Hz, the average sound absorption coefficient of the whole sound absorption decoration structure is greater than 0.5, and the sound absorption effect is good.

[0054] The fixing mode of the sound absorption enhancement layer 8 can be that the adhesive is brushed on the surface of the waterproof paint layer 7, and then laid; or directly fixed on the wall body by screws.

[0055] The sound absorption enhancement layer 8 is sequentially provided with the following layer structures: a first non-woven base cloth layer 81, a honeycomb paper layer 82, a second non-woven cloth layer 83, and an aluminum sheet layer 84; the first non-woven base cloth layer 81 is provided with the honeycomb paper layer 82, and the honeycomb paper layer 82 is arranged on the first non-woven base cloth layer 81 by adhesive bonding; the second non-woven cloth layer 83 is arranged on the side of the honeycomb paper layer 82 away from the first non-woven base cloth layer 81, and the second non-woven cloth layer 83 is arranged on the honeycomb paper layer 82 by adhesive bonding.

[0056] The second non-woven cloth layer 83 is provided with the aluminum sheet layer 84 on the side away from the honeycomb paper layer 82, and the aluminum sheet layer 84 is arranged on the surface of the second non-woven cloth layer 83 by adhesive bonding, and the aluminum sheet layer 84 is provided with a plurality of perforations 85.

[0057] When the sound that is not completely absorbed by the sound absorption wall cloth 1 first reaches the cavity of the honeycomb paper layer 82 through the aluminum sheet layer 84 and the second non-woven cloth layer 83, the sound can be further weakened, and then can be further absorbed by the first non-woven base cloth layer 81 to achieve better sound absorption effect. Compared with the sound absorption wall cloth 1, the sound absorption enhancement layer 8 adopts a cavity sound absorption method, which can achieve the effect of superposition of sound absorption.

[0058] The thickness of the first non-woven base cloth layer 81 is 0.5~1.0mm; the thickness of the honeycomb paper layer 82 is 3~5mm; the thickness of the second non-woven cloth layer 83 is 0.2~0.5mm; the thickness of the aluminum sheet layer 84 is 0.7mm, the aperture of the perforation 85 is 2~3mm, and the coverage rate of the perforation 85 is 20~30%.

[0059] The arrangement of the second non-woven cloth layer 83 can increase the bonding strength of the honeycomb paper layer 82 and the aluminum sheet layer 84, and can also reduce the thickness of the aluminum sheet layer 84.

[0060] Further, the aluminum flake layer 84 is provided with a frosted layer 86 on both sides. The frosted layer 86 can be formed by polishing or brushing a frosted paint to increase the bonding strength with the adhesive.
