Description

Technical Field

[0001] This utility model belongs to the field of sound absorption equipment, and in particular relates to a particulate composite sound absorption board. Background Technology

[0002] To address the environmental and human health hazards posed by ultrafine dust generated from the aging and deterioration of inorganic mineral fiber materials (such as glass wool and mineral wool) after long-term use, a granular sound-absorbing material, known as microparticle sound-absorbing material, has been developed. This material boasts significant green and low-carbon advantages. It can utilize solid waste as a raw material to form a green and recyclable "solid waste utilization industry." Furthermore, different types of green cementitious materials are used to coat the particle surface, creating microparticle gradation and interface modification technology to meet various needs such as sound absorption, corrosion resistance, temperature resistance, weather resistance, fire resistance, and aesthetics. Moreover, the microparticle material is produced using a non-fired, low-temperature molding process, resulting in no harmful substance volatilization, simple production, rapid molding, no curing required, and high efficiency through assembly line operation. However, existing microparticle materials consist of cementitious solvents and inorganic particles. Under excessive impact, these components can be damaged, causing the cross-section to turn white, making repair complex. Additionally, the installation method for microparticle materials involves a double-fastening method of applying adhesive to a light steel keel and fixing with screws, making installation and removal complex.

[0033] Please see Figures 1 to 4 The present invention provides a microparticle composite sound-absorbing panel 100, comprising a perforated plate 40, a protective layer 30, a microparticle plate 10, and a clamping structure 50. The perforated plate 40 includes a base plate 414 and first-type side edges 401 and second-type side edges 402 extending upward along the perimeter of the base plate 414. The first-type side edges 401, second-type side edges 402, and the base plate 414 form an accommodating space. In one embodiment, the cross-section of the vacant space is approximately rectangular, with the first-type side edges 401 and second-type side edges 402 spaced apart, such as two first-type side edges 401 facing each other and two second-type side edges 402 facing each other. In other embodiments, the vacant space may also have other shapes.

[0034] The first type of side 401 includes a vertical portion 412 extending upward from the base plate 414 and a support portion 410 disposed approximately parallel to the base plate 414 from the end of the vertical portion 412. The first type of side 401 is approximately L-shaped, that is, the cross-section after the vertical portion 412 and the support portion 410 are connected is approximately L-shaped. The end of the second type of side 402 is approximately parallel to the support portion 410 of the first type of side 412, so that the microparticle plate 10 accommodated in the accommodating space can form a flat structure. In one embodiment, the perforated plate 40 can be a metal plate, such as carbon steel, stainless steel, or aluminum alloy, with a thickness ranging from 0.4 mm to 3 mm. The metal microperforated plate has high strength, good toughness, is not easily damaged, can be processed into various shapes, and has advantages such as fire resistance, non-combustibility, non-absorbency, moisture resistance, mildew resistance, insect resistance, dust resistance, no pollution, high temperature resistance, and ability to withstand the scouring of high-speed airflow. The base plate 414 has a plurality of perforations with a perforation rate ≥2%, and the diameter of each perforation can be one or a combination of round holes, square holes, and triangular holes. In one embodiment, the perforated plate (40) is formed by stamping a metal plate and then flanging its four sides to form the first type of side, the second type of side, the base plate, and the accommodating space. In other embodiments, the perforated plate 40 can also be a non-metallic plate (e.g., a polymer plate, a polymer film, a fiber fabric, etc.).

[0035] The protective layer 30 and the microparticle plate 10 are disposed within the accommodating space of the perforated plate 40, wherein the protective layer 30 is located between the base plate 414 and the microparticle plate 10. In one embodiment, the protective layer 30 is one or more of non-woven fabric or sound-absorbing paper; the base plate 414 and the protective layer 30 are connected by an adhesive, and the protective layer 30 is bonded to the honeycomb grid by an adhesive.

[0036] The locking structure 50 includes a mounting portion 505 and a guide portion 503 perpendicular to the mounting portion 505. A boss 501, generally arc-shaped, protrudes from the guide portion 501 towards the accommodating space at its end. One or more locking structures 50 are respectively fixedly connected to the support portion 410 of the first type side 401 by fasteners 60, thereby mounting the locking structure 50 onto the first type side 401. In one embodiment, threaded openings are provided at opposite positions of the mounting portion 505 and the support portion 410, allowing fasteners (such as screws) to fix the locking structure 500 to the first type side 401 through the threaded openings. In other embodiments, the mounting portion 505 can be fixedly connected to the support portion 410 by other types of fasteners (such as snap-fit ​​fasteners). In other embodiments, the locking structure 50 can be disposed on one of the first type side 401.

[0037] The microparticle board 10 is a particulate sound-absorbing material composed of inorganic particles bonded together by a gelling solvent. The gelling solvent is one or more of the following: silicone, epoxy resin, acrylic, polyurethane, and phenolic resin. The inorganic particles are one or a mixture of several of the following: aeolian sand, manufactured sand, ceramsite, cenospheres, hollow alumina spheres, hollow glass beads, and industrial construction waste.

[0038] Please see Figure 5 In one embodiment, the protective layer 30 is provided with a honeycomb grid 20 on the surface of the particle board 10. When the particulate sound-absorbing material is filled into the accommodating space, the sound-absorbing board can be made dense and seamless, so that the particle board has high strength in addition to sound absorption performance.

[0039] This embodiment effectively enhances the impact resistance of the sound-absorbing panel by placing the microparticle plate inside the perforated plate. At the same time, the L-shaped clamping structure provides a continuous straight-line holding force, ensuring uniform and firm holding force, which is suitable for larger tensile areas and facilitates easy installation and removal.

[0040] Please refer to the following: Figures 6 to 7 This is another embodiment of the particle composite sound-absorbing panel. Unlike the previous embodiment, in this embodiment, the first type side does not require a separate clip structure; instead, the clip structure is installed on the second type side. Specifically, the clip structure 50 extends upward from the second type side 402 and beyond the end face of the vertical portion 412 of the first type side 401 (or beyond the surface of the particle panel 10), and one or more convex indentations 412 are provided at the extended position. In this embodiment, the indentations 412 protrude in the direction opposite to the accommodating space, and the spacing between each indentation 412 is between 50 and 300 mm. In this embodiment, the clip structure 50 and the second type side 402 can be integrally formed.

[0041] The clip structure of this embodiment adopts a convex indentation structure. Its mounting structure has a point-like nail-holding force, which is discontinuous and suitable for smaller tensile areas. It can also achieve the purpose of convenient installation and removal.

[0042] In one embodiment, in conjunction with the above embodiments, a clip structure can be provided on both the first type side and the second type side. That is, an L-shaped clip structure can be fixedly installed on the first type side, and a fixed installation with one or more convex indentations can be provided on the second type side. In this way, the sound-absorbing panel can be applied to a larger tensile area or a smaller tensile area as needed.

[0043] In one embodiment, the manufacturing process of the above-mentioned particle composite sound-absorbing panel may include:

[0044] The first step is to punch the hole shape and diameter on the perforated plate 40 with the perforation rate and specifications set. Then, the plate is folded into a box shape by turning the edges around, and then the surface is treated with anti-corrosion.

[0045] The second step is to evenly apply adhesive to the bottom side of the inner wall of the perforated plate 40, and then flatly paste the protective layer 30 (such as non-woven fabric or sound-absorbing paper) onto the inner wall surface; at this time, the alternative is to apply adhesive to one side of the honeycomb grid and paste it onto the surface of the protective layer 30.

[0046] The third step is to pour the uniformly mixed gelling solvent and inorganic granular semi-finished product into the perforated plate 40 and smooth the surface.

[0047] The fourth step is to place it at a temperature of 90~150℃ for 30~80 minutes, and then take it out.

[0048] The fifth step involves using fasteners to fix the L-shaped clip structure 50 to the first type side to obtain the microparticle composite sound-absorbing board; or, in the first step, one or more convex indentations 412 are directly set on the second type side as required, in which case the fifth step is unnecessary.

[0049] The applicant declares that this utility model is illustrated through the above embodiments, but it is not limited to the above detailed methods, meaning that this utility model cannot be implemented without relying on the above detailed methods. Those skilled in the art should understand that any improvements to this utility model, equivalent substitutions of raw materials, additions of auxiliary components, and selection of specific methods, etc., all fall within the protection and disclosure scope of this utility model.
