Description

Technical Field

[0001] This utility model belongs to the field of enamel steel plate technology, specifically, it relates to an enamel steel plate structure with good sound insulation effect. Background Technology

[0002] Traditionally, decorative panels for walls, columns, countertops, and ceilings were made of cement products, marble slabs, granite slabs, ceramic tiles, coated wallpaper, and gypsum board. However, some of these materials were expensive, others couldn't withstand sun and rain, had poor thermal insulation and sound absorption, and some were too heavy, making installation inconvenient. Therefore, metal curtain wall panels, such as aluminum and steel panels, are now widely used. They offer better surface properties and aesthetic appeal, especially enamel-coated steel panels, which are particularly outstanding in terms of corrosion resistance, weather resistance, and surface smoothness. However, ordinary enamel-coated steel panels lack sound-insulating materials, resulting in poor heat insulation and soundproofing.

[0003] Therefore, there is an urgent need for a new type of enamel steel plate with good sound insulation properties. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide an enamel steel plate structure with good sound insulation effect, avoiding the trouble of the previous enamel steel plates being relatively thin and lacking sound insulation effect.

[0005] To solve the above-mentioned technical problems, this utility model discloses an enamel steel plate structure with good sound insulation effect, comprising:

[0006] The double-layer substrate is composed of an outer enamel steel plate layer and an inner enamel steel plate layer welded together, and the double-layer substrate has a hollow cavity.

[0007] Butyl rubber damping sheet, the butyl rubber damping sheet is attached to the inner wall of the hollow cavity and is bonded to the outer enamel steel plate layer and the inner enamel steel plate layer by epoxy resin adhesive layer;

[0008] The sound-absorbing cotton assembly is filled in a hollow cavity and includes an outer sound-absorbing cotton layer, an inner sound-absorbing cotton layer, and an intermediate non-woven fabric layer that bonds the two together.

[0009] Multiple EPDM rubber strips are provided and spaced apart on the butyl rubber damping sheet for bonding the sound-absorbing cotton assembly and the butyl rubber damping sheet.

[0010] According to one embodiment of the present invention, the outer enamel steel plate layer is folded back around its perimeter and welded to the inner enamel steel plate layer, and the joint is filled with sealant.

[0011] According to one embodiment of the present invention, the outer sound-absorbing cotton layer is selected from 50mm thick 48kg / m³ glass wool; the inner sound-absorbing cotton layer is selected from 20mm thick 64kg / m³ glass wool.

[0012] According to one embodiment of the present invention, the thickness of the outer enamel steel plate layer is 5-8mm; the thickness of the inner enamel steel plate layer is 3-5mm.

[0013] According to one embodiment of the present invention, the thickness of the butyl rubber damping sheet is 3-6 mm.

[0014] According to one embodiment of the present invention, the EPDM rubber strip has a mesh.

[0015] Compared with the prior art, the present invention can achieve the following technical effects:

[0016] The double-layer enamel steel plate structure, combined with a hollow cavity, enhances the sound insulation effect. The internal sound-absorbing cotton component further absorbs sound, and the butyl rubber damping sheet is attached to the inner wall of the hollow cavity. Through damping and vibration reduction, it consumes the vibration energy of the steel plate, suppresses resonance and structural sound transmission, and further improves the sound insulation of mid-low frequency. The EPDM rubber strips are set at intervals, which not only flexibly fix the sound-absorbing cotton component and the butyl rubber damping sheet, but also block the rigid sound bridge between the sound-absorbing cotton and the damping sheet through their own elasticity, reducing vibration transmission.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. Attached Figure Description

[0021] Double-layer substrate 10, outer enamel steel plate layer 11, inner enamel steel plate layer 12, butyl rubber damping sheet 20, sound-absorbing cotton assembly 30, outer sound-absorbing cotton layer 31, inner sound-absorbing cotton layer 32, middle non-woven fabric layer 33, EPDM rubber strip 40. Detailed Implementation

[0022] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0023] Please refer to Figure 1 , Figure 1 This is a schematic diagram of an enamel steel plate structure with good sound insulation effect according to an embodiment of the present invention.

[0024] As shown in the figure, an enamel steel plate structure with good sound insulation effect includes: a double-layer substrate 10, which is welded together by an outer enamel steel plate layer 11 and an inner enamel steel plate layer 12, and the double-layer substrate 10 has a hollow cavity; a butyl rubber damping sheet 20, which is attached to the inner wall of the hollow cavity and bonded to the outer enamel steel plate layer 11 and the inner enamel steel plate layer 12 by an epoxy resin adhesive layer; a sound-absorbing cotton assembly 30, which fills the hollow cavity and includes an outer sound-absorbing cotton layer 31, an inner sound-absorbing cotton layer 32, and an intermediate non-woven fabric layer 33 bonding the two; and multiple EPDM rubber strips 40, which are spaced apart from the butyl rubber damping sheet 20 and used to bond the sound-absorbing cotton assembly 30 and the butyl rubber damping sheet 20.

[0025] In one embodiment of this utility model, the double-layer substrate 10 is made of two inner and outer enamel steel plates welded together, forming a hollow cavity in the middle to improve the sound absorption effect. Specifically, a butyl rubber damping sheet 20 is first attached to the inner wall of the hollow cavity through an epoxy resin adhesive layer. The butyl rubber damping sheet 20 is made of butyl rubber and is attached as a whole. It consumes the vibration energy of the steel plate through damping and vibration reduction, suppresses resonance and structural sound transmission, and improves the sound insulation effect. Preferably, the thickness of the butyl rubber damping sheet 20 is 3-6mm.

[0026] The sound-absorbing cotton assembly 30 consists of an outer sound-absorbing cotton layer 31, an inner sound-absorbing cotton layer 32, and a middle non-woven fabric layer 33, ensuring high sound absorption. The inner and outer sound-absorbing cotton layers are selected from pearl cotton, and the middle non-woven fabric layer 33 connects and transitions to prevent the sound-absorbing cotton layers from shifting. Additionally, EPDM rubber strips 40 connect the sound-absorbing cotton assembly 30 and the butyl rubber damping sheet 20 at intervals, achieving elastic fixation while simultaneously breaking the rigid sound bridge between the sound-absorbing cotton and the damping sheet through their own elasticity, reducing vibration transmission. Preferably, the EPDM rubber strip 40 has a mesh design, which enhances the sound absorption effect.

[0027] In a preferred embodiment, the outer enamel steel plate layer 11 is folded back around its perimeter and welded to the inner enamel steel plate layer 12 to form a frame structure. Sealant is then filled at the joints to ensure a sealing effect.

[0028] The outer sound-absorbing cotton layer 31 of this utility model is selected from 50mm thick 48kg / m³ glass wool; the inner sound-absorbing cotton layer 32 is selected from 20mm thick 64kg / m³ glass wool. The different thicknesses of glass wool are used in a differentiated design to work together to efficiently absorb sound waves, continuously attenuate noise, and achieve a more efficient sound absorption effect.

[0029] In addition, the outer enamel steel plate layer 11 has a thickness of 5-8mm; the inner enamel steel plate layer 12 has a thickness of 3-5mm. The thickness difference design, with the outer layer being thicker, ensures sufficient external strength. At the same time, the different thicknesses of the inner and outer layers can stagger the matching frequencies, avoiding the superposition of sound insulation troughs at a single frequency.

[0030] In summary, this utility model enhances sound insulation through a double-layer enamel steel plate structure combined with a hollow cavity. The internal sound-absorbing cotton component further absorbs sound, and the butyl rubber damping sheet adheres to the inner wall of the hollow cavity. Through damping and vibration reduction, it consumes the vibration energy of the steel plate, suppresses resonance and structural sound transmission, and further improves the sound insulation of mid-to-low frequencies. The EPDM rubber strips are spaced apart, which not only elastically fix the sound-absorbing cotton component and the butyl rubber damping sheet, but also block the rigid sound bridge between the sound-absorbing cotton and the damping sheet through their own elasticity, reducing vibration transmission.

[0031] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
