For this reason, it is often difficult for the conventional marine wall panels to satisfy the requirements of light weight (light weight), high fire resistance, and high sound insulation.

Detailed Description

The inventive concepts of the present disclosure will be described below using terms commonly used by those skilled in the art to convey the substance of their work to others skilled in the art. These inventive concepts may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.

The invention will be described in detail below with reference to the drawings in connection with embodiments.

In the prior art, the sound insulation performance of the structure is directly limited by the surface density, the sound insulation effect is better as the surface density is higher, but the increase of the surface density can cause that the cabin wall board structure cannot meet the requirement of light weight; the requirement of the ship cabin wall plate structure on the fireproof performance determines that the range of materials is limited to inorganic materials or composite materials with high fireproof performance, and organic materials with light weight and good sound absorption/insulation effects cannot be selected. The existing ship wallboard is often in the structure form of a metal layer, a fireproof cotton core material and a metal layer, and the conventional ship wallboard is acoustically in the structure of a conventional double-layer sound insulation (namely a double-layer metal layer) +a sound absorption material. Although the structural form can meet certain light and fire-resistant requirements, the sound insulation amount is generally 30-33 dB, and the new requirements (the highest requirements are more than 45 dB) of the International maritime organization on ship noise cannot be met. For this reason, it is often difficult for the conventional marine wall panels to satisfy the requirements of light weight (light weight), high fire resistance, and high sound insulation.

In order to solve the problems of low light weight degree, poor sound insulation effect and the like of the wallboard applied to the ship in the prior art, the embodiment provides a light fire-resistant sound insulation cabin wallboard, as shown in figures 1-10, the wallboard comprises an acoustic super-surface component, fire-resistant sound absorption layers 2 and fire-resistant surface plates 1 are sequentially arranged on two sides of the acoustic super-surface component, the acoustic super-surface component comprises N frames 4 and N+1 acoustic super-surface plates 3, N is any positive integer, the frames 4 are of grid-shaped structures, the frames 4 are arranged between any two adjacent acoustic super-surface plates 3, a cavity 5 is formed between the acoustic super-surface plates 3 and the frames 4, a frequency modulation mass block 6 is arranged in the cavity 5, and the frequency modulation mass block 6 is connected with the acoustic super-surface plates 3.

Because the frame 4 is in a grid shape, a plurality of cavities 5 can be enclosed between the frame 4 and the acoustic super-surface plates 3 at two sides of the frame, for any one cavity 5, a frequency modulation mass block 6 is arranged at one side, close to the cavity 5, of the acoustic super-surface plate 3, one side of the frequency modulation mass block 6 is connected with the acoustic super-surface plate 3, and the other side extends into the cavity 5.

The acoustic super-surface plate 3 has an acoustic super-structure surface, is an ultrathin planar structure formed by artificial micro units, improves the isolation capability by utilizing the local anti-resonance effect of the film packaging structure in a specific frequency band range, has the physical characteristics of plane, ultrathin and the like, can directly adopt the conventional acoustic super-surface structure in the prior art, and can also be processed and produced according to the conventional design and manufacturing method of the acoustic super-surface structure in the prior art, and the description is omitted. Wherein the frame 4 may also be configured as an acoustic super-structure surface, forming an acoustic super-surface frame, such that the frame 4 forms an acoustic super-surface structure in combination with the acoustic super-surface plate 3.

Therefore, the acoustic super-surface component is embedded into the traditional double-layer sound insulation (namely, a double-layer metal layer) +sound absorption structure, so that the sound insulation performance of the wallboard can be effectively improved besides good light weight and fire resistance performance of the wallboard; meanwhile, the acoustic super-surface assembly is formed by arranging the acoustic super-surface plates 3 on two sides of the frame 4 respectively, so that the coverage of at least two sound insulation frequency bands can be formed, and the sound insulation range can be effectively widened.

For the acoustic subsurface assembly, the number of frames 4 can be adjusted, i.e. the frames can be 1 layer, 2 layers, 3 layers or multiple layers, and correspondingly, the acoustic subsurface plate 3 is correspondingly increased to 2 layers. The acoustic super-surface assembly is formed by arranging the acoustic super-surface plates 3 and the frames 4 layer by layer in sequence, so that two side panels of the acoustic super-surface assembly are acoustic super-surface plates 3, and one frame 4 is arranged between any two adjacent acoustic super-surface plates 3 in the acoustic super-surface assembly; therefore, more sound insulation frequency bands can be covered according to actual application requirements. For example: in fig. 1, the number of frames 4 is one, the number of acoustic super surface plates 3 is 2, and the frames 4 are arranged between the two acoustic super surface plates 3; in fig. 4, 3 frames 4 and 4 acoustic super surface plates 3 are arranged, the acoustic super surface plates 3 and the frames 4 are sequentially stacked layer by layer, and one frame 4 is arranged between any two adjacent acoustic super surface plates 3. Of course, on the basis of the arrangement mode of the acoustic super surface assembly, the number of the components in fig. 1 and 4 is not limited, and the number of the components in fig. 1 and 4 can be 2 layers of frames 4, corresponding to 3 layers of acoustic super surface plates 3, or N layers of frames 4, corresponding to n+1 layers of acoustic super surface plates 3, wherein N is any positive integer.

The thickness of the acoustic super-surface plate 3 can be adjusted respectively, the structure and the size of each frame 4 are adjusted respectively, and the size, the quality and the shape of each frequency modulation mass block 6 are adjusted respectively, so that the sound insulation frequency band of the wallboard can be adjusted, different sound insulation frequency bands can be covered, the effect of widening the sound insulation frequency band is achieved, and the sound insulation effect meeting the application requirements can be provided according to the actual application environment.

Furthermore, for the arrangement of the tuning mass 6, if only one side of the acoustic super-surface plate 3 constitutes the cavity 5, the tuning mass 6 is arranged in the cavity 5; if the two sides of the acoustic super-surface plate 3 form the cavities 5, the frequency modulation mass blocks 6 can be arranged in any one of the cavities 5 at the two sides of the acoustic super-surface plate 3, or the frequency modulation mass blocks 6 can be arranged in the cavities 5 at the two sides of the acoustic super-surface plate 3.

Although the acoustic super-surface can play a certain role in sound insulation, in order to reduce the modulus of the film material and obtain the low-frequency sound insulation effect, the existing acoustic super-surface sound insulation member almost entirely adopts organic elastic materials such as silica gel and the like as super-surface core materials, and the materials obviously cannot meet the requirements of the ship cabin wall plate on the fireproof performance (at least the temperature resistance of more than 700 ℃ is generally required). Moreover, the acoustic super-surface structure can generally generate a good sound insulation effect only on a single frequency band, the sound insulation frequency band is relatively narrow, and the air noise of a broadband is difficult to effectively insulate. Therefore, the frequency modulation mass block 6 is arranged on the acoustic super-surface plate 3 and used for adjusting the super-sound insulation frequency, and according to practical application requirements, the effect of adjusting the super-surface sound insulation frequency band can be achieved by using the frequency modulation mass blocks with different weights, so that the acoustic super-surface plate 3 and the wall plate have different sound insulation effects. For example: the use of a relatively small frequency modulation mass can provide the acoustic super surface plate 3 with high sound insulation capability at 100-600 Hz, while the use of a relatively large and relatively heavy frequency modulation mass can provide the acoustic super surface plate 3 with relatively high sound insulation capability at 600-1000 Hz.

In addition, for the two acoustic super-surface plates 3 at two sides of any layer of frame 4, the thicknesses of the plate bodies can be the same or different, and when the thicknesses of the plate bodies are different, different high-performance sound insulation frequency bands can be formed; preferably, the thickness of the acoustic super surface plate 3 is 0.02 mm-4 mm. The acoustic super-surface plate 3 is made of iron sheet, thin steel sheet, stainless steel sheet, high-temperature-resistant composite material plate, aluminum alloy plate or other material plates, so that the traditional low-modulus organic material (such as silica gel) is prevented from being used as the acoustic super-surface material, and the fire resistance and high-temperature resistance of the acoustic super-surface plate 3 are improved.

The frequency modulation mass block 6 may be made of metal materials such as iron, steel, aluminum, etc., or composite materials, plastics, nylon, etc., or any other materials with a certain rigidity and capable of providing a certain weight.

For both acoustic supersurface plates 3 on both sides of either frame 4, either the tuning mass 6 or none of the tuning masses 6 may be provided, or one acoustic supersurface plate 3 may be provided with a tuning mass 6 and the other one may not be provided with a tuning mass 6. Preferably, the acoustic super-surface plates 3 are provided with the frequency modulation mass blocks 6, and the frequency modulation mass blocks 6 are inconsistent in size, weight and shape, so that the two acoustic super-surface plates 3 have high sound insulation performance in different frequency bands, and the frequency band range with high sound insulation performance is widened.

For the tuning mass 6, reference may be made to fig. 8-10, and the tuning mass 6 may be circular, rectangular, polygonal, annular, etc., and the size and the setting position of the tuning mass 6 may be determined according to calculation or experiment. The frequency modulation mass block 6 can be manufactured in a cutting, casting, mould pressing, injection molding mode and the like, the frequency modulation mass block 6 is connected with the acoustic super-surface plate 3 into a whole in a bonding, welding and other connecting modes, and can also be prefabricated with the acoustic super-surface plate 3 into a whole structure in a mould pressing mode and the like.

The frame 4 is made of iron, steel, aluminum alloy, composite material, or the like. The frame 4 is in a grid structure, has a certain topological structure, forms a plurality of grid holes 41, and on the basis of the structure that the acoustic super-surface plates 3 are arranged on two sides of the frame 4, for any one grid hole 41, the acoustic super-surface plates 3 block two ends of the grid hole 41, so that a cavity 5 is formed.

Referring to fig. 5-7, the shape of the grid holes 41 may be square, rectangular, circular, triangular, hexagonal or other shaped holes, and the size and shape of any two grid holes 41 may be the same or different. When the grid holes 41 are different in size (as shown in fig. 6), the acoustic super-surface structure formed by the frame 4 and the acoustic super-surface plate 3 can form different high-sound-insulation frequency bands, so that the sound insulation performance of the wallboard is improved.

The frame 4 and the acoustic super-surface plate 3 are connected into a whole in a bonding, welding and other modes, the frame 4 and the acoustic super-surface plate 3 can be prefabricated into a whole structure in a mould pressing mode and other modes, or the frame 4, the acoustic super-surface plate 3 and the frequency modulation mass block 6 can be prefabricated into a whole structure in a mould pressing mode and other modes.

The cavity 5 is a cavity space surrounded by the frame 4, the acoustic super-surface plate 3 and the frequency modulation mass block 6 on the basis of assembly, and can be kept in a hollow state, namely, can be filled with air. In order to further improve the sound insulation and fire resistance of the wallboard, the cavity 5 is preferably filled with aerogel and sound absorbing materials, and the aerogel can be aerogel particles or aerogel powder, so that the wallboard has excellent sound absorbing performance and heat resistance; the sound absorbing material comprises at least one of rock wool, ceramic fiber cotton/felt, superfine glass cotton/felt, aerogel felt, vermiculite, polyurethane foam, phenolic foam, perlite particles/blocks, foamed ceramics, foamed glass and the like.

The fireproof surface plate 1 is made of iron sheet, thin steel sheet, high temperature resistant composite material plate, etc. with the surface density of 1-8 kg/m ² The high-frequency noise isolation effect can be enhanced, and the fire resistance and the light weight performance of the wallboard can be fully ensured. While at the same time. When the fire-resistant surface plate 1 is a high-temperature resistant composite material, the high-temperature resistant composite material comprises 100 parts of phenolic resin (the mass parts are the same as below), 10-30 parts of porcelain filler, 15-60 parts of magnetizable substance, 3-10 parts of curing agent, 3-10 parts of accelerator and 150-450 parts of fiber reinforced material; the high temperature resistant composite material is prepared by a hot pressing process, and the fire resistance temperature reaches 600-1000 ℃.

The fireproof sound-absorbing layer 2 comprises at least one of rock wool, ceramic fiber cotton/felt, aerogel felt, superfine glass wool and other materials, and has high heat resistance, high heat insulation performance and good sound-absorbing performance. Alternatively, the fire-resistant sound-absorbing layer 2 is formed by filling the space between the fire-resistant surface plate 1 and the acoustic surface plate 3 with a corresponding material.

The fireproof surface plate 1 and the fireproof sound absorbing layer 2 are connected into a whole through hot-pressing bonding or cold bonding. The fireproof sound absorbing layer 2 and the acoustic super surface plate 3 are integrally connected through hot-press bonding or cold bonding, specifically, "between the fireproof sound absorbing layer 2 and the acoustic super surface plate 3" refers to between the fireproof sound absorbing layer 2 and the acoustic super surface plate 3 adjacent to the fireproof sound absorbing layer 2, which is all the same in the application, and details are not repeated.

In order to further improve the sound insulation performance of the wallboard, a first damping layer 7 is arranged between the fireproof surface plate 1 and the fireproof sound absorbing layer 2, and/or a second damping layer 8 is arranged between the fireproof sound absorbing layer 2 and the acoustic super-surface plate 3; preferably, the first damping layer 7 and the second damping layer 8 are damping materials or paint, the first damping layer 7 is connected with one side of the fire-resistant surface plate 1 facing the fire-resistant sound absorbing layer 2 in an adhering or coating mode, and the second damping layer 8 is connected with one side of the acoustic super surface plate 3 facing the fire-resistant sound absorbing layer 2 in an adhering or coating mode. Wherein the first damping layer 7 is made of inorganic damping material to ensure good fire resistance near the surface layer of the panel, the acoustic super surface panel 3 is positioned near the inner layer of the panel and is subjected to relatively low temperature, and the second damping layer 8 is made of inorganic damping material or organic damping material.

On the basis of the light refractory and sound-proof cabin wall plate, the application provides a manufacturing method of the light refractory and sound-proof cabin wall plate, which comprises the following steps:

s1, cutting an iron block into a frequency modulation mass block 6, cutting an iron sheet into a fireproof surface plate 1, cutting an aluminum alloy rod into an aluminum alloy rod section, welding the aluminum alloy rod section into a square frame 4, cutting a stainless steel plate into an acoustic super surface plate 3, and cutting rock wool as a fireproof sound absorption layer 2;

with reference to fig. 5, the frame 4 in step S1 is square and has a grid-like structure, and is obtained by welding individual pole segments. In addition, the step S1 may be regarded as a prefabrication process of each component, and the corresponding structural member may also be customized directly from other companies, so that the step S1 may be skipped, and the manufacturing of the light fire-resistant sound-insulating cabin wall panel may be performed directly from the step S2.

S2, scribing the surface of the acoustic super-surface plate 3, coating an adhesive on one side of the frequency modulation mass block 6, bonding the frequency modulation mass block 6 to a scribing area on the surface of the acoustic super-surface plate 3, and waiting for the adhesive to be cured;

in step S2, two acoustic super-surface plates 3 with frequency modulation mass 6 bonded thereto need to be manufactured for subsequent processing and production.

and S7, coating a fireproof structural adhesive on the side, away from the fireproof surface plate 1, of the fireproof sound absorbing layer 2 in the step S6, and bonding the fireproof sound absorbing layer 2 and the side, away from the frame 4, of the acoustic super surface plate 3.

If the panel has only one layer of frames 4, performing steps S1-S5 can produce an acoustic subsurface assembly; if the multi-layer frame 4 is required to be disposed in the wall panel, after performing steps S1-S5, referring to the relevant bonding operation of steps S1-S5, sequentially bonding the frame 4 and the acoustic super surface plate 3 on the surface to be bonded (i.e. the side of the acoustic super surface plate 3 that is not bonded yet), and ensuring that each grid hole 41 of the frame 4 is filled with aerogel powder until the number of layers of the frame 4 and the acoustic super surface plate 3 reaches the requirement, thereby obtaining the acoustic super surface assembly under the multi-layer frame 4 structure. After the acoustic subsurface assembly is produced, steps S6, S7 continue to be performed.

In addition, according to the operations of steps S6 and S7, the fire-resistant surface plate 1 and the fire-resistant sound-absorbing layer 2 on the other side of the wall plate are bonded, and in view of the fact that the operations are completely identical, the description thereof will not be repeated. In the steps S2, S3 and S5, the adhesives are all epoxy structural adhesives; likewise, the fire-resistant structural adhesive can also be an epoxy structural adhesive.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
