Description

Technical Field

[0001] This utility model relates to the field of composite board technology, and in particular to a fiber-reinforced polyurethane foam composite board. Background Technology

[0002] The main characteristics of polyurethane foam layers are porosity, low relative density, and high specific strength. Polyurethane foam layers possess excellent physical and mechanical properties, acoustic properties, electrical properties, and chemical resistance. In particular, rigid polyurethane foam layers have exceptionally low thermal conductivity, making them a high-quality thermal insulation and cold insulation material. Furthermore, polyurethane foam layers have good processing and molding properties. Composite panels made from polyurethane foam layers also exhibit excellent physical and mechanical properties, acoustic properties, electrical properties, and chemical resistance. Therefore, the applications of polyurethane foam layer composite panels are becoming increasingly diverse. For example, they can be used as decorative wall panels for interior and exterior walls of buildings, new lightweight sound-insulating wall panels, sound-damping panels, roofs and floors of large public places, reinforcement panels for bridge bodies, bridge decks, and bridge bottoms of dams, interior decorative panels for high-speed rail, blades for wind turbines, ship wall panels, temporary barracks, radar panels, etc.

[0003] Chinese patent CN209365512U discloses a fiber-reinforced polyurethane foam composite board. A resin matrix is ​​disposed between at least two parallel fiber felts, with reinforcing fibers uniformly distributed within the resin matrix. The resin matrix, reinforcing fibers, and two fiber felts constitute a single-layer board. At least one single-layer board with longitudinally oriented reinforcing fibers is disposed between the two transversely oriented single-layer boards. An adhesive layer is disposed between the longitudinally oriented single-layer board and the two transversely oriented single-layer boards. The longitudinally oriented single-layer board is connected to the two transversely oriented single-layer boards via the adhesive layer to form a multi-layer board. This application has advantages such as suitability for large-scale continuous production, lightweight and high-strength properties, simple structure, and high production efficiency. It can effectively improve the overall mechanical properties of the board, especially its shear performance, effectively solving the cracking problem of container flooring and reducing costs.

[0004] However, the aforementioned patent cannot effectively insulate sound during use, allowing external noise to easily enter the room and affect the occupants. Furthermore, the polyurethane foam composite board of this patent does not have fireproof and waterproof functions, making the polyurethane foam composite board unsafe during subsequent use. Utility Model Content

[0024] Please see Figures 1-5 A fiber-reinforced polyurethane foam composite board includes a matrix 100, a sound insulation layer 200 fixedly connected to the bottom of the matrix 100, and a sound-absorbing mechanism. The sound-absorbing mechanism includes sound-absorbing cotton 210, a sound-absorbing foam board 220, sound-absorbing holes 230, and sound-absorbing cotton 240. The sound-absorbing cotton 210 is fixedly connected to the top of the inner cavity of the sound insulation layer 200, and is used to eliminate noise. The sound-absorbing foam board 220 is fixedly connected to the bottom of the sound-absorbing cotton 210, and is used to improve the noise reduction effect. Sound-absorbing holes 230 are evenly distributed at the bottom of the sound-absorbing foam board 220, and are used to reduce noise. Sound-absorbing materials are fixedly connected to the bottom of the inner cavity of the sound insulation layer 200. The sound-absorbing cotton 240 is used to reduce noise. By setting up the sound-absorbing cotton 210, sound-absorbing foam board 220, sound-absorbing holes 230, and sound-absorbing cotton 240, the composite board can achieve noise reduction and sound insulation effects. The sound-absorbing cotton 240 initially reduces noise, and the sound-absorbing foam board 220 further absorbs the noise. The sound waves bounce back and forth in the sound-absorbing holes 230 on the sound-absorbing foam board 220, gradually consuming and reducing the noise waves, thereby improving the sound insulation effect. Finally, the sound-absorbing cotton 210 absorbs the remaining sound waves, allowing the composite board to completely isolate noise, thus giving the composite board sound insulation and noise reduction functions and improving the use effect of the composite board.

[0025] A polyurethane foam layer 110 is fixedly connected to the top of the substrate 100. The polyurethane foam layer 110 is used to improve the strength of the composite board. Reinforcing fibers 111 are provided inside the polyurethane foam layer 110 to further enhance its strength. A fireproof layer 120 is fixedly connected to the top of the polyurethane foam layer 110 for fire protection. A fireproof coating 130 is fixedly connected to the top of the fireproof layer 120 for fire protection. An aerogel felt 140 is fixedly connected to the top of the 30, and the aerogel felt 140 is used for thermal insulation. An insulation coating 150 is fixedly connected to the top of the aerogel felt 140, and the insulation coating 150 is used for thermal insulation. A connecting layer 160 is fixedly connected to the top of the insulation coating 150, and the connecting layer 160 is used to connect the decorative layer 170. The decorative layer 170 is fixedly connected to the top of the connecting layer 160, and the decorative layer 170 is used to improve the aesthetics of the composite panel. A wear-resistant coating 180 is applied to the top of the decorative layer 170. 80 is used to improve the wear resistance of the composite board. A moisture-proof layer 250 is fixedly connected to the bottom of the sound insulation layer 200. The moisture-proof layer 250 is used for moisture protection. A waterproof coating 260 is fixedly connected to the bottom of the moisture-proof layer 250. The waterproof coating 260 is used for waterproofing. A base plate 270 is fixedly connected to the bottom of the waterproof coating 260. The base plate 270 is used for installation on the ground and walls. Anti-slip textures 280 are provided on the bottom of the base plate 270. The composite board includes a fireproof layer 120, a fireproof coating 130, an aerogel felt 140, and a moisture-proof layer 250. The composite board is fireproof and waterproof thanks to the waterproof coating 260. The aerogel felt 140 can insulate against heat, and together with the fireproof layer 120 and the fireproof coating 130, the composite board has a fire-retardant effect. Then, the moisture-proof layer 250 and the waterproof coating 260 block moisture and humidity, preventing moisture and humidity from penetrating the composite board, thus giving the composite board a waterproof and moisture-proof function. This improves the practicality of the fireproof and waterproof function of the composite board.

[0026] In practical use, the bottom plate 270 of the composite board is first attached to the ground or wall, and the anti-slip texture 280 is used to complete the installation of the composite board. Then, during the use of the composite board, the sound insulation cotton 240 initially reduces noise, and the sound insulation foam board 220 further reduces noise. The sound waves bounce back and forth in the sound-absorbing holes 230 on the sound insulation foam board 220, which gradually consumes and reduces the noise waves, thereby isolating external noise. The aerogel felt 140 can insulate heat. At the same time, the fireproof layer 120 and the fireproof coating 130 give the composite board a fireproof and flame-retardant effect. Finally, the moisture-proof layer 250 and the waterproof coating 260 block moisture and humidity, preventing moisture and humidity from penetrating the composite board, thus giving the composite board a waterproof and moisture-proof function. Finally, the decorative layer 170 provides an aesthetic function, and the wear-resistant coating 180 protects the decorative layer 170 to prevent it from being damaged during the use of the composite board, thus affecting its appearance.
