Description

Technical Field

[0001] This utility model relates to the field of insulation board technology, specifically to a composite shock-absorbing insulation board with good sound insulation function. Background Technology

[0002] In the construction industry, traditional sound insulation materials made of wood panels can only provide a single sound insulation function, but lack structural support and vibration damping capabilities. They are cumbersome to install and take up space. They do not have a high suppression effect on low-frequency vibrations and are also prone to moisture and mold, resulting in a short service life. Traditional thermal insulation materials have certain thermal insulation performance, but they are insufficient in sound insulation, lack vibration damping function, and rely on thick stacking. They have a high water absorption rate, and their thermal insulation performance drops significantly in humid environments. They also pose environmental risks of fiber shedding. Traditional vibration damping materials can only control vibrations and lack sound insulation and thermal insulation functions. When used alone, they take up a lot of space and cannot meet the needs of ultra-thin walls. Utility Model Content

[0003] The purpose of this utility model is to solve the problems in the construction field where traditional sound insulation materials have limited functions, are cumbersome to construct, have insufficient low-frequency vibration suppression and are prone to moisture, thermal insulation materials lack sound insulation and shock absorption functions, rely on thickness and have poor environmental performance, and shock absorption materials lack sound insulation and thermal insulation functions, occupy a large space and have low adaptability. This utility model provides a composite shock absorption and thermal insulation board with good sound insulation function.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: A composite vibration damping and heat insulation board with good sound insulation function includes a vibration damping layer, a base layer disposed on the outer side of the vibration damping layer, a heat insulation layer disposed on the outer layer of the base layer, and a protective layer disposed on the outer side of the heat insulation layer. The vibration damping layer includes an elastic keel and embedded ribs, with the embedded ribs disposed on both sides of the elastic keel. The base layer includes a board, sound-absorbing holes, and sound-absorbing grooves, with the sound-absorbing holes disposed on the inner side of the board and the sound-absorbing grooves disposed on the outer side of the board.

[0005] Furthermore, the elastic keel is made of rubber, which can reduce the impact noise of the floor slab, and the embedded bone is a glass fiber reinforced polyurethane block, forming a "keel-bone" damping vibration structure, which can evenly disperse the concentrated vibration energy through the "rigid-flexible" coupling effect of the bone-keel interface.

[0006] Furthermore, the substrate is made of high-density fiberboard, and the sound-absorbing holes are evenly distributed on the inner side of the substrate. The mass effect of the high-density fiberboard and the resonant sound absorption of the sound-absorbing holes work together to significantly block human voices.

[0007] Furthermore, the insulation layer is a polyurethane foam layer, which is bonded to the base layer with an acrylic adhesive and bonded to the insulation layer with a pressure-sensitive adhesive. The aluminum foil layer serves as a second moisture barrier, forming a double protection with the closed-cell structure of the inner polyurethane foam.

[0008] Furthermore, the protective layer includes a fire-retardant coating and a moisture-proof membrane. The fire-retardant coating is an intumescent silica coating, and the moisture-proof membrane is an aluminum-plastic composite membrane, which is applied to the outside of the fire-retardant coating. The aluminum-plastic membrane can effectively prevent condensate from the exterior wall from seeping into the insulation layer and avoid the increase in thermal conductivity of polyurethane foam due to water absorption.

[0009] Furthermore, a butyl rubber layer is provided between the shock-absorbing layer and the base layer, which is bonded to the elastic keel and the board through a hot-pressing process. This can adapt to slight structural deformation and avoid cracks caused by rigid connection between the boards.

[0010] Furthermore, an aluminum foil layer is provided on the outside of the insulation layer, which is bonded to the insulation layer with pressure-sensitive adhesive. The aluminum foil layer serves as a second moisture barrier, forming a double protection with the closed-cell structure of the inner polyurethane foam.

[0011] Compared with the prior art, this utility model provides a composite shock-absorbing and heat-insulating board with good sound insulation function, which has the following beneficial effects: This composite vibration-damping insulation board with excellent sound insulation properties utilizes a composite structure of rubber elastic keel and glass fiber reinforced polyurethane embedded skeleton in the vibration-damping layer. Leveraging the damping effect of "flexible keel + rigid skeleton," it reduces vibration transmission efficiency and significantly suppresses low-frequency vibrations. The high-density fiberboard base layer, combined with inner sound-absorbing holes and outer sound-absorbing grooves, forms a "resonance-scattering" broadband sound absorption system, increasing the noise absorption coefficient while providing structural support. The insulation and protective layers further enhance thermal barrier and safety performance, overcoming the performance limitations of traditional single-function boards. Through its multi-layered structural design, this composite vibration-damping insulation board achieves efficient integration of sound insulation, vibration damping, and thermal insulation functions.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example:

[0015] like Figures 1-5 As shown, a composite shock-absorbing and heat-insulating board with good sound insulation function includes a shock-absorbing layer 1, a base layer 2 on the outside of the shock-absorbing layer 1, a heat-insulating layer 3 on the outside of the base layer 2, and a protective layer 4 on the outside of the heat-insulating layer 3.

[0016] Among them, the insulation layer 3 is a polyurethane foam layer, which is bonded to the base layer 2 with acrylic adhesive. The thermal resistance of 20mm thick polyurethane foam is equivalent to that of 100mm thick red brick masonry. Among them, the protective layer 4 includes a fireproof coating and a moisture-proof membrane. The fireproof coating is an intumescent silica coating, and the moisture-proof membrane is an aluminum-plastic composite membrane, which is covered on the outside of the fireproof coating. The aluminum-plastic membrane can effectively prevent condensate from the exterior wall from seeping into the insulation layer, avoid the increase in thermal conductivity of polyurethane foam due to water absorption, and its tear resistance can withstand accidental impacts during construction, thus protecting the internal functional layer. Among them, an aluminum foil layer is provided on the outside of the insulation layer 3, which is bonded to the insulation layer 3 by pressure-sensitive adhesive. The aluminum foil layer serves as a second moisture barrier, forming a double protection with the closed-cell structure of the inner polyurethane foam. like Figures 1-5 As shown, the damping layer 1 includes an elastic keel 11 and an embedded keel 12, with the embedded keel 12 disposed on both sides of the elastic keel 11; Among them, the elastic keel 11 is made of rubber, which can reduce the impact sound of the floor. The EPDM rubber has excellent weather resistance and is suitable for outdoor soundproof wall scenarios. Among them, the embedded bone 12 is a glass fiber reinforced polyurethane block, forming a "keel-bone" damping vibration structure, which can evenly disperse concentrated vibration energy through the "rigid-flexible" coupling effect of the bone-keel interface, avoiding material fatigue cracking caused by local stress concentration. like Figures 1-5 As shown, the base layer 2 includes a board 21, sound-absorbing holes 22 and sound-absorbing grooves 23. The sound-absorbing holes 22 are located on the inner side of the board 21, and the sound-absorbing grooves 23 are located on the outer side of the board 21. Among them, the board 21 of the base layer 2 is a high-density fiberboard, and the sound-absorbing holes 22 are evenly distributed on the inner side of the board 21. The mass effect of the high-density fiberboard and the resonance sound absorption of the sound-absorbing holes work together to significantly block human voices. It can be directly used as a partition wall keel panel to reduce the additional keel installation process. Among them, a butyl rubber layer is provided between the damping layer 1 and the base layer 2. It is bonded to the elastic keel 11 and the board 21 through a hot pressing process. It can adapt to slight structural deformation and avoid cracks caused by rigid connection between the boards.
