Description

Technical Field

[0001] The invention relates to the technical field of soundproof rooms, in particular to a soundproof room. Background Art

[0002] At present, the design of soundproof rooms often involves adding sound insulation materials to the original room to achieve the sound insulation effect. Soundproof rooms of this design generally use metal or polymer composite sandwich panels or foam panels. Although they can effectively isolate sound, they are relatively expensive.

[0003] In addition, the existing metal composite panel technology has a high density, which leads to high transportation and installation costs. According to statistics, it accounts for 35%-40% of the total project cost. Polymer foam materials: polyester fiber / melamine foam has the advantage of lightweight (8-12kg / m 2 ), but it has fatal defects such as being flammable and releasing toxic gases (UL94 HB grade) and being non-degradable (it takes more than 200 years to decompose naturally).

[0004] Although the design life of metal soundproof rooms (aluminum / steel plates) is usually 10-15 years, market research shows that more than half of temporary indoor soundproofing scenes (such as exhibition live broadcast rooms, short-term production lines, and film and television shooting studios) have a usage period of only 3-24 months or even shorter.

[0005] Therefore, in the field of short-term indoor acoustic solutions (typical cycle 3-24 months), traditional metal soundproof rooms have a serious resource mismatch due to their extremely long design life (>10 years) and over-specification mechanical properties (load capacity exceeds actual requirements by 400%). This "killing a chicken with a sledgehammer" type of technical solution not only leads to the loss of 65% of the capital investment in material costs, but also generates additional carbon emissions (about 8.5kWh / m2) due to the complex metal disassembly process. 2 ) and low reuse rates (<30%). Especially in fast-paced business environments, such as temporary live broadcast studios and short-cycle production lines, metal structures only last for less than 15% of their lifecycle, from production to disposal. The remaining 85% of resource investment becomes an environmental burden. This urgently requires the industry to develop soundproof rooms that are "precisely matched to their lifecycle."

[0006] To this end, we have improved and innovated the technology of existing materials and proposed a method of mainly using cardboard to make soundproof rooms, which reduces the cost of generation, manufacturing, transportation and installation, and has lower carbon emissions throughout the entire life cycle, making it more environmentally friendly. Summary of the Invention

[0008] To achieve the above objectives, the present invention provides the following technical solutions: a soundproof room, the main body of which is formed by folding a single sheet of paper or splicing multiple sheets of paper. The use of paper is more environmentally friendly and reduces the cost of production, transportation and installation.

[0009] Preferably, the paper is a mixture of one or more of corrugated paper, honeycomb paper, gypsum composite paper, aramid paper, and carbon fiber reinforced paper, wherein the mixing includes mixed use in multiple positions and composite use between multiple layers in the same position, and the combination can be selected according to actual conditions.

Except for the bottom surface, this part is less stressed and the main consideration is sound insulation, so the composite paperboard of corrugated paper and honeycomb paper is used.

[0012] Preferably, the composite paperboard comprises at least one flame retardant coating layer and one waterproof film layer, thereby improving service life and safety.

[0013] Preferably, the flame retardant coating is an ammonium phosphate-zinc borate composite system with a coating amount of 10-30 g / m 2 .

[0014] Preferably, the composite paperboard comprises, from outside to inside, a first corrugated paper layer, a first honeycomb paper layer, a second honeycomb paper layer, and a second corrugated paper layer, and the composite of corrugated paper and honeycomb paper ensures strength while increasing attractiveness.

[0015] Preferably, the first honeycomb paper layer and the second honeycomb paper layer both have gradient pore sizes, and the first honeycomb paper layer and the second honeycomb paper layer both have small pores facing the sound source, and the first corrugated paper layer and the second corrugated paper layer have small holes on the flutes, thereby improving the suction effect.

[0016] Preferably, a paper-based sealing strip is provided at the joint of the frame to improve the sealing performance.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the present invention uses a combination of multiple types of paper to replace traditional metal profiles and polymer materials, which can effectively reduce production costs, and the paper is more environmentally friendly and is very suitable for application designs that match short-term needs; the present application alternately stacks honeycomb paper and corrugated cardboard to form an impedance gradient interface, ensuring the corresponding strength while improving the sound insulation, sound absorption and noise reduction effects.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-6 The present invention provides a technical solution: a soundproof room, the main body of which is formed by folding a single sheet of paper or splicing multiple sheets of paper. The paper is a mixture of one or more of corrugated paper, honeycomb paper, gypsum composite paper, aramid paper, and carbon fiber reinforced paper. The mixing includes mixed use in multiple positions and composite use of multiple layers in the same position. Of course, other types of paper currently available in the art are also applicable.

[0027] Specifically, the soundproof room can be pieced together by folding and creasing the whole paper. This method has high requirements on the size of the whole paperboard and the strength of the corners is limited. Therefore, a further method is proposed. The soundproof room can be pieced together by folding and creasing the whole paperboard. Figure 1 The frame 1 and panel 2 shown are assembled together, wherein the frame 1 part is made of high-density paper, and the assembly method can be gluing or fixing with fixing parts to form a frame structure, and then the other surfaces are formed by paper with lower density. Paper-based sealing strips are set at the joints of the frame, and specifically kraft paper impregnated with silicone oil can be used for connection and sealing.

[0028] Specifically, each surface of the soundproof room is formed by composite paperboard including corrugated paper and honeycomb paper, and the composite form can be that multiple layers are bonded together using an adhesive.

[0029] In order to increase the service life and safety, the composite paperboard includes at least one flame retardant coating and one waterproof film. The flame retardant coating is an ammonium phosphate-zinc borate composite system with a coating amount of 10-30g / m 2 .

[0030] Specifically put forward a form, such as Figure 3 As shown, the composite paperboard comprises, from outside to inside, a first corrugated paper layer 101, a first honeycomb paper layer 102, a second honeycomb paper layer 103, and a second corrugated paper layer 104, and each layer is connected by adhesive.

[0031] The first corrugated paper layer 101 and the second corrugated paper layer 104 can both be V-shaped, five-layer corrugated paper with a flute height of 4-8 mm. The cross-sectional view is as follows: Figure 2 As shown, the two corrugated layers are arranged in a V-shaped staggered arrangement, and small holes are opened on the corrugations of the first corrugated paper layer 101 and the second corrugated paper layer 104, with a hole diameter of about 2 mm, and are arranged in an array, so that the overall resonance frequency can be adjusted to 250±50 Hz, reducing the impact of resonance on sound insulation.

[0032] Specifically, in order to improve the sound insulation effect, the first honeycomb paper layer 102 and the second honeycomb paper layer 103 both adopt gradient pore size, that is, each honeycomb paper contains at least two or more honeycomb hole layers (different honeycomb hole layers are separated by inner paper), and the first honeycomb paper layer 102 and the second honeycomb paper layer 103 both have small pores facing the sound source, that is, large pores are on the inner side of the composite paper layer (such as Figure 4 As shown), the honeycomb aperture range is 3-10mm, and the porosity is ≥60%. The use of this gradient aperture method can increase the absorption of the sound frequency band, achieve high-frequency absorption of 500-4000Hz, and improve the sound insulation effect.

[0033] like Figure 5 As shown, it is a cross-sectional view including a flame retardant coating 105 , a waterproof membrane 106 , a first corrugated paper layer 101 , a first honeycomb paper layer 102 , a second honeycomb paper layer 103 , and a second corrugated paper layer 104 .

[0034] It should be noted that since the bottom surface of the soundproof room bears a large load, other hard materials such as composite flooring can be used to connect this part with the above-mentioned frame. And if holes are required at the corresponding position of panel 2 to be used as air inlets and outlets or ventilation equipment, the cross-section of the holes can also be sealed with kraft paper impregnated with silicone oil or other materials.

[0035] In addition to this Figure 6 As shown, a montmorillonite paper layer 107 can be added to achieve the effect of self-absorption of moisture and adjustment of internal humidity when the humidity is high.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
