Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for building panels, and in particular to a sound-insulating and heat-insulating polyester fiber building sound insulation board. Background Technology

[0002] As we all know, with the improvement of people's living standards, the requirements for the comfort and quietness of the building's indoor environment are getting higher and higher. The application of sound and heat insulation materials is crucial in the construction and decoration process. Polyester fiber, as a commonly used sound insulation material, has been widely used in the field of building sound insulation due to its advantages such as environmental friendliness and good sound absorption performance.

[0003] Existing building sound insulation panels have been found to have limited sound insulation effects, with weak blocking capabilities for high-frequency and low-frequency noise. They are insufficient to meet the high sound insulation requirements of environments such as residences and commercial spaces near main traffic arteries. Furthermore, they cannot effectively block the transfer of external heat, leading to increased indoor temperatures and air conditioning energy consumption in summer, and difficulty in maintaining indoor temperatures in winter, reducing living and usage comfort. This reduces the stability of the device and results in poor practicality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sound insulation and heat insulation polyester fiber building sound insulation board that can effectively improve sound insulation and has good heat insulation effect, thereby improving the user's living comfort and enhancing the stability of the device, thus enhancing its practicality.

[0005] This utility model discloses a sound-insulating and heat-insulating polyester fiber building sound insulation board, which includes a board body, a surface layer, a sound insulation layer, and a heat insulation layer. The surface layer is provided on the outer side of the board body, and the sound insulation layer is provided on the outer side of the surface layer. The heat insulation layer is provided on the outer side of the sound insulation layer.

[0006] Preferably, the surface layer is a flame-retardant polyester fiber layer, and its surface is provided with a number of raised guide grooves, which are distributed in an irregular curved shape.

[0007] Preferably, the sound insulation layer is composed of two layers of polyester fiber sound-absorbing cotton, and a honeycomb-shaped air cavity is provided between two adjacent layers of polyester fiber sound-absorbing cotton.

[0008] Preferably, the heat insulation layer is a polyurethane foam layer, and an aluminum foil reflective layer is provided on the side of the heat insulation layer away from the sound insulation layer.

[0009] Preferably, it also includes two sets of T-shaped clips, with the left end of the main body of the plate evenly connected to the right end of the two sets of T-shaped clips, and two sets of T-shaped slots evenly provided on the top right end of the main body of the plate.

The top and bottom of the outer sides of the four sets of sleeves are respectively connected to the inner side of a set of annular plates. One end of the multiple sets of annular plates is respectively connected to one end of the heat insulation layer.

[0011] Compared with existing technologies, the beneficial effects of this utility model's sound-insulating and heat-insulating polyester fiber building sound insulation board are as follows: The main body of the board serves as the core carrier, consisting of a surface layer, a sound insulation layer, and a heat insulation layer stacked sequentially. During use, external sound and heat act on the board. The surface layer first initially scatters and absorbs the sound while resisting external heat. Then, the sound insulation layer further absorbs sound energy.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] like Figures 1 to 3 As shown, this utility model discloses a sound-insulating and heat-insulating polyester fiber building soundproofing board, comprising a board body 1, including a surface layer 2, a sound insulation layer 3, and a heat insulation layer 4. The surface layer 2 is disposed on the outer side of the board body 1, and the sound insulation layer 3 is disposed on the outer side of the surface layer 2. The heat insulation layer 4 is disposed on the outer side of the sound insulation layer 3. The board body, as the core carrier, is composed of the surface layer, the sound insulation layer, and the heat insulation layer stacked sequentially. During use, external sound and heat act on the board. The surface layer first initially scatters and absorbs the sound while resisting external heat. Then, the sound insulation layer further absorbs the sound energy. Finally, the polyurethane foam layer and aluminum foil reflective layer of the heat insulation layer block heat transfer, thereby achieving sound and heat insulation functions. This effectively improves the sound insulation effect and also has a good heat insulation effect, enhancing the user's living comfort and thus improving the stability of the device, thereby enhancing its practicality.

[0020] As a preferred embodiment of the above, the surface layer 2 is a flame-retardant polyester fiber layer with several raised guide grooves on its surface, which are distributed in an irregular curved shape. When sound waves contact the surface layer, the irregular curved guide grooves change the direction of sound wave propagation, causing scattering. Some sound waves enter the interior of the guide grooves and consume energy through friction with the flame-retardant polyester fiber layer. The guide grooves extend the propagation path of the sound waves by scattering them, thus improving the sound absorption efficiency. Actual measurements show that, compared to a planar structure, the surface layer with guide grooves can increase the sound absorption coefficient in the 1000-4000Hz frequency band by 15-20%, and the flame-retardant polyester fiber layer meets the fire resistance requirements of building materials. When exposed to open flames, it can slow down the combustion rate and reduce the risk of fire, thus enhancing its practicality.

[0021] As a preferred embodiment of the above, the sound insulation layer 3 is composed of two layers of polyester fiber sound-absorbing cotton, with a honeycomb-shaped air cavity between adjacent layers of polyester fiber sound-absorbing cotton. High-frequency sound waves are absorbed by the outer layer of polyester fiber sound-absorbing cotton, and then the remaining sound waves enter the honeycomb-shaped air cavity. The unabsorbed low-frequency sound waves are further attenuated when they penetrate the inner layer of polyester fiber sound-absorbing cotton, and the air vibration and friction with the cavity wall consume energy. Polyester fiber sound-absorbing cotton is good at absorbing mid-to-high frequencies (500-4000Hz), and the honeycomb-shaped air cavity has a good buffering effect on low frequencies (50-500Hz), forming a complementary effect. In addition, the honeycomb structure reduces the weight of the board and the building load while ensuring the sound insulation effect, thus enhancing practicality.

[0022] As a preferred embodiment of the above, the heat insulation layer 4 is a polyurethane foam layer, and an aluminum foil reflective layer is provided on the side of the heat insulation layer 4 away from the sound insulation layer 3; when heat conduction passes through the polyurethane foam layer, the extremely low thermal conductivity (about 0.022-0.024 W / m・K) slows down heat transfer, while the aluminum foil reflective layer reflects radiant heat (such as sunlight) back to the outside, reducing heat absorption, thus enhancing practicality.

[0023] As a preferred embodiment of the above, it also includes two sets of T-shaped locking blocks 5. The left end of the main body 1 of the board is uniformly connected to the right end of the two sets of T-shaped locking blocks 5, and two sets of T-shaped slots are uniformly provided on the top right end of the main body 1 of the board. The T-shaped locking blocks of one board are aligned with the T-shaped slots of the adjacent board and pushed in laterally until they are fully engaged, forming a continuous sound and heat insulation barrier. No additional tools are required, and it can be operated by a single person, thus enhancing its practicality.

[0024] As a preferred embodiment of the above, it also includes multiple sets of annular plates 6 and four sets of sleeves 7. A set of reserved holes is provided on the front and rear sides of the top of the main body 1 of the plate. The outer sides of the two sets of sleeves 7 are respectively fitted into the inner sides of the reserved holes of the main body 1 of the plate. The top and bottom of the outer sides of the four sets of sleeves 7 are respectively connected to the inner sides of the annular plates 6. One end of the multiple sets of annular plates 6 is respectively connected to one end of the heat insulation layer 4. The combination of sleeves and annular plates improves the impact resistance of the plate by 30%, and it can withstand lateral pressure of 50 N / cm². In addition, the sleeves are made of low thermal conductivity materials (such as nylon), which reduces heat transfer through the fixing point and avoids local condensation. It is suitable for various installation methods (such as hanging and embedded), adapts to different building structure requirements, and thus enhances practicality.

[0025] This utility model discloses a sound-insulating and heat-insulating polyester fiber building sound insulation board. During operation, the first board is fixed to the keel using a sleeve. The T-shaped locking block of the second board is aligned with the T-shaped locking groove of the first board, and then pushed in laterally to complete the splicing. Subsequent boards are installed sequentially, each board fixed to the keel using a sleeve to ensure the ring-shaped board is tightly against the wall. Through the synergistic effect of the surface guide channel, the honeycomb cavity of the sound insulation layer, and the reflective foil of the heat insulation layer, it achieves a three-in-one function of sound insulation (STC≥45dB), heat insulation (thermal resistance≥1.8m²·K / W), and fire resistance (B1 level). Before completing the above actions, it is first moved to the user's desired location.

[0026] The terms “vertical,” “horizontal,” “left,” “right,” and similar expressions used in this article are for illustrative purposes only.

[0027] In this utility model, the terms "first," "second," and "third" do not represent a specific quantity or order, but are merely used to distinguish names.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
