Description

Technical Field

[0001] This utility model relates to the field of building energy-saving materials technology, specifically to a noise-reducing rigid fireproof insulation board. Background Technology

[0002] In the modern construction industry, as people's requirements for living and working environments continue to increase, the performance of building insulation materials also needs to be continuously upgraded. They must not only meet the basic thermal insulation needs, but also have good fire resistance to ensure the safety of buildings and people. At the same time, with the increasing severity of urban noise pollution, building materials with noise reduction functions are receiving more and more attention.

[0003] Existing building insulation boards have relatively limited functions and lack excellent noise reduction performance, making it difficult for them to provide continuous and effective noise reduction in complex building acoustic environments.

[0004] For example, CN215152568U discloses a new sound-absorbing and noise-reducing material, a fireproof and heat-insulating board, which includes two symmetrically arranged aesthetically pleasing surface layers. A fireproof layer is fixedly connected to the inner side of each of the two symmetrical aesthetically pleasing surface layers. A heat-insulating layer is fixedly connected to the side of the fireproof layer away from the corresponding aesthetically pleasing surface layer. A noise-resistant layer is fixedly connected between the heat-insulating layers of the two aesthetically pleasing surface layers. Although this patent includes a noise-resistant layer, it is a single structure. This structure lacks a targeted design for noise of different frequencies and has no gradient sound absorption mechanism to deal with high, medium, and low frequency sound waves respectively. As a result, the noise reduction structure has a narrow frequency band coverage, and the overall noise reduction efficiency is limited, making it difficult to achieve efficient noise suppression.

[0005] Therefore, it is necessary to invent a noise-reducing rigid fireproof insulation board to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a noise-reducing rigid fireproof insulation board to solve the problem that the above-mentioned technologies do not have excellent noise reduction performance, making it difficult for the insulation board to provide a continuous and effective noise reduction effect in complex building acoustic environments.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a noise-reducing rigid fireproof insulation board, comprising an insulation board body, wherein the insulation board body is provided with an inner layer structure, an insulation layer, a fireproof layer, a noise-reducing layer and a protective outer layer stacked sequentially from the inside to the outside along the thickness direction, and adjacent layers are fixedly connected by an adhesive. The inner layer structure includes a moisture-proof layer and a reinforcing layer. The noise-reducing layer includes gradient polyester fiber sound-absorbing cotton, a butyl rubber damping interlayer and a honeycomb high-density fiber cement sound insulation board, wherein the butyl rubber damping interlayer is sandwiched between the gradient polyester fiber sound-absorbing cotton and the honeycomb high-density fiber cement sound insulation board.

[0008] Preferably, one side of the reinforcing layer is tightly bonded to the inner side of the insulation layer, and the other side is fixedly connected to one side of the moisture-proof layer, the other side of which is used to bond to the building wall base.

[0009] Preferably, the moisture-proof layer is a polyethylene film, the reinforcing layer is a glass fiber mesh, and the glass fiber mesh is uniformly distributed within the reinforcing layer.

[0010] Preferably, the insulation layer is made of rigid polyurethane foam.

[0011] Preferably, the fireproof layer is made of glass magnesium fireproof board.

[0012] Preferably, the side of the gradient polyester fiber sound-absorbing cotton away from the butyl rubber damping interlayer is bonded to the outer side of the fireproof layer, and the side of the honeycomb high-density fiber cement sound insulation board away from the butyl rubber damping interlayer is bonded to the inner side of the protective outer layer.

[0013] Preferably, the two sides of the butyl rubber damping interlayer are bonded to gradient polyester fiber sound-absorbing cotton and honeycomb high-density fiber cement sound insulation board respectively by water-based sound insulation adhesive.

[0014] Preferably, the protective outer layer is made of high-strength fiber-reinforced cement board and the surface is treated with an anti-ultraviolet coating.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model achieves efficient noise reduction by setting up a multi-layered composite noise reduction layer. The gradient polyester fiber sound-absorbing cotton can first absorb the mid-to-high frequency noise propagating in the air, the butyl rubber damping interlayer can weaken the low frequency noise generated by structural vibration through its own damping characteristics, and the honeycomb high-density fiber cement sound insulation board further blocks the unabsorbed noise. The three layers work together to form a "absorbing-blocking-isolating" noise reduction system, which greatly improves the overall sound insulation effect. 2. This utility model optimizes the connection method between the noise reduction layer and the adjacent structure to ensure noise reduction stability. The butyl rubber damping interlayer is bonded to the gradient polyester fiber sound-absorbing cotton and the honeycomb high-density fiber cement sound insulation board on both sides by water-based sound insulation adhesive. This not only avoids the sound leakage problem caused by gaps in traditional connection methods, but also helps to weaken vibration noise through the damping characteristics of the adhesive, further enhancing the noise reduction performance.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model provides, for example Figure 1-4 The noise-reducing rigid fireproof insulation board shown includes an insulation board body 1. The insulation board body 1 is stacked in sequence from the inside to the outside along the thickness direction, including an inner layer structure 101, an insulation layer 102, a fireproof layer 103, a noise-reducing layer 104, and a protective outer layer 105. Adjacent layers are fixedly connected by an adhesive. The inner layer structure 101 includes a moisture-proof layer 1011 and a reinforcing layer 1012. The noise-reducing layer 104 includes a gradient polyester fiber sound-absorbing cotton 1041, a butyl rubber damping interlayer 1042, and a honeycomb high-density fiber cement sound insulation board 1043. The butyl rubber damping interlayer 1042 is sandwiched between the gradient polyester fiber sound-absorbing cotton 1041 and the honeycomb high-density fiber cement sound insulation board 1043.

[0020] One side of the reinforcing layer 1012 is tightly attached to the inner side of the insulation layer 102, and the other side is fixedly connected to one side of the moisture-proof layer 1011. The other side of the moisture-proof layer 1011 is used to adhere to the base of the building wall. The moisture-proof layer 1011 is a polyethylene film, the reinforcing layer 1012 is a fiberglass mesh, and the fiberglass mesh is evenly distributed in the reinforcing layer 1012. The insulation layer 102 is made of rigid polyurethane foam, the fireproof layer 103 is made of magnesium oxide fireproof board, and the protective outer layer 105 is made of high-strength fiber-reinforced cement board, and the surface is treated with an anti-ultraviolet coating.

[0021] In this embodiment, the fiberglass mesh of the reinforcing layer 1012 can improve the overall structural strength of the insulation board body 1, preventing cracking and deformation due to external forces or temperature changes during long-term use; the polyethylene film of the moisture-proof layer 1011 can block moisture from the wall base layer from penetrating into the insulation layer 102, preventing the insulation performance of the insulation layer 102 from decreasing after it gets damp, while protecting the wall base layer from moisture erosion; the rigid polyurethane foam of the insulation layer 102 has a low thermal conductivity, which can effectively block the transfer of heat between indoors and outdoors, meeting the building insulation requirements; the glass magnesium fireproof board of the fireproof layer 103 has excellent high temperature resistance and flame retardant properties, which can delay the spread of fire in fire scenarios and improve the fire resistance rating of the building; the high-strength fiber-reinforced cement board of the protective outer layer 105 is impact-resistant and wear-resistant, and can resist the damage of the external environment to the internal structure; the anti-ultraviolet coating on the surface can prevent the board from aging and fading due to long-term exposure to sunlight, making it suitable for outdoor or high-light scenarios.

[0022] The side of the gradient polyester fiber sound-absorbing cotton 1041 away from the butyl rubber damping interlayer 1042 is bonded to the outer side of the fireproof layer 103, and the side of the honeycomb high-density fiber cement sound insulation board 1043 away from the butyl rubber damping interlayer 1042 is bonded to the inner side of the protective outer layer 105. The two sides of the butyl rubber damping interlayer 1042 are bonded to the gradient polyester fiber sound-absorbing cotton 1041 and the honeycomb high-density fiber cement sound insulation board 1043 respectively by water-based sound insulation adhesive.

[0023] In this embodiment, a three-level noise reduction system of "absorption-blocking-isolation" is constructed: the porous structure of gradient polyester fiber sound-absorbing cotton 1041 can actively absorb mid-to-high frequency noise propagating in the air and reduce noise reflection inside the board; the butyl rubber damping interlayer 1042 has high damping characteristics and can convert low-frequency noise generated by structural vibration into heat energy consumption, weakening the transmission of low-frequency noise; the honeycomb high-density fiber cement sound insulation board 1043 has high density and strong sound insulation performance, which can further block the remaining noise that has not been absorbed, achieving efficient control of noise across the entire frequency band; and the water-based sound insulation adhesive can not only achieve a firm connection between the components of the noise reduction layer 104, but its own sound insulation properties can also help fill the tiny gaps between the components, further optimizing the noise reduction effect.
