Aluminum-plastic composite panel with fireproof structure

Abstract

The invention discloses an aluminum-plastic composite board with a fireproof structure, which relates to the technical field of aluminum-plastic composite boards and comprises a fireproof layer. A top aluminum plate mounting plate is installed at the bottom of the fireproof layer. In cooperation with an active fireproof component, when a fire occurs, heat is firstly conducted to a heat-conducting column contact column through a metal heat-conducting sheet, and then transferred to a heat-conducting metal conduction sheet, and then transferred to a fixed-line heat-conducting end, so that the temperature is rapidly increased. The fixed-line heat-conducting end transfers heat to a polyethylene fracture node, causing it to melt and fracture. A polypropylene fiber connecting line ring that loses support will also melt, so that a restricting hook is released, and a needle-piercing trigger quickly pierces a flame-retardant gas storage device to release the flame-retardant gas. With the rapid release of the flame-retardant gas, it quickly spreads around the flame to form a protective layer, effectively isolating the contact between the flame and surrounding combustibles, thereby slowing down or even preventing the further spread of the fire.

At the same time, due to the fast response speed of the overall device, the time from the flame contact to the release of the flame-retardant gas is extremely short, which can greatly reduce the losses that may be caused in the initial stage of the fire. After the fire is initially controlled, the monitoring device inside the flame-retardant gas storage device will continuously detect the change of the fire situation. When there is a tendency of the fire to reignite, it can be immediately restarted to release more flame-retardant gas to maintain effective suppression of the fire.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] In the present invention, referring to Figure 1 - Figure 8 as shown: A plastic-aluminum composite panel with a fireproof structure includes a fireproof layer 1. A top aluminum plate mounting plate 3 is installed at the bottom of the fireproof layer 1. A plurality of shape memory alloy grooves 10 are provided on the inner wall surface of the top aluminum plate mounting plate 3. An active fire protection component 7 is installed inside each of the plurality of shape memory alloy grooves 10;

[0030] The active fire prevention component 7 includes a bottom mounting member 701. A fire-resistant connection block 702 is tightly connected to the side end of the bottom mounting member 701. A top operation mounting member 703 is tightly connected to the side end of the fire-resistant connection block 702. The bottom mounting member 701 and the top operation mounting member 703 are tightly connected. A plurality of overflow hole grooves 704 are formed on the surfaces of the bottom mounting member 701 and the top operation mounting member 703. A fixed support frame 705 is installed on the surface of the bottom mounting member 701. A support frame 707 is tightly connected to the side end of the fixed support frame 705. A stabilizing ring 709 is integrally formed at the top of the support frame 707. A flame retardant gas trigger member 708 is sleeved inside the stabilizing ring 709. A rotating groove frame 7093 is installed on the surface of the support frame 707. A limiting hook 7094 is rotatably connected inside the rotating groove frame 7093. The side wall surface of the limiting hook 7094 is connected to the side wall of the rotating groove frame 7093 through a compression spring. A compression elastic spring member 7092 is tightly connected to the side end of the fixed support frame 705. A needle trigger member 7091 is tightly connected to the side end of the compression elastic spring member 7092. A flame retardant gas storage 7090 is installed at the side end of the needle trigger member 7091. The needle trigger member 7091 is used to drive the flame retardant gas storage 7090 to slide on the top wall sliding groove of the support frame 707 under the compression and resilience of the compression elastic spring member 7092, so as to trigger and puncture the flame retardant gas trigger member 708.

[0031] A polypropylene fiber connecting wire ring 7095 is sleeved outside the limiting hook 7094. A polyethylene fracture node 7096 is tightly connected to the side end of the polypropylene fiber connecting wire ring 7095. A fixed wire heat conduction end 7097 is tightly connected to the side end of the polyethylene fracture node 7096. A heat conduction metal conduction plate 7098 is tightly connected to the side end of the fixed wire heat conduction end 7097.

[0032] The heat conduction metal conduction plate 7098 penetrates through the side of the fixed support frame 705 and is tightly connected to a heat conduction column contact column 706. A metal heat conduction sheet is tightly connected to the top of the heat conduction column contact column 706.

[0033] In a specific solution, when a fire occurs, the high temperature generated by the flame is first conducted to the heat conduction column contact column 706 through the metal heat conduction sheet during the fire. This process is the first step of heat transfer. Subsequently, the heat conduction column contact column 706 transfers the received heat to the heat conduction metal conduction sheet 7098, further enhancing the heat transfer efficiency. Then, the heat is transferred to the fixed wire heat conduction end 7097 through the heat conduction metal conduction sheet 7098, causing the fixed wire heat conduction end 7097 to rapidly heat up. The fixed wire heat conduction end 7097 continues to transfer the received heat to the polyethylene fracture node 7096. Since the melting point of the polyethylene material is relatively low, approximately between 120°C and 135°C, under the action of high temperature, the polyethylene fracture node 7096 will rapidly melt and break. The fracture of the polyethylene fracture node 7096 causes the polypropylene fiber connection wire loop 7095 to lose its original supporting effect. The melting point of the polypropylene fiber connection wire loop 7095 is relatively high, approximately between 160°C and 170°C, but it will also rapidly melt under the condition of losing support. When the polypropylene fiber connection wire loop 7095 melts, the limiting hook 7094 is released under the action of the compression elastic spring member 7092 and no longer restricts the needle triggering member 7091. As a result, the needle triggering member 7091 is rapidly pushed by the compression elastic spring member 7092 to pierce the flame retardant gas storage 7090, releasing the stored flame retardant gas. Overall, this effectively improves the response speed and reliability of the operation. When a fire occurs, through this rapid heat transfer and material melting mechanism, the flame retardant gas can be rapidly and effectively released, thereby playing a fire prevention role, effectively preventing the spread of the fire, and ensuring people's life and property safety. Moreover, with the rapid release of the flame retardant gas, it rapidly diffuses around the flame, forming a protective layer that effectively isolates the contact between the flame and the surrounding combustibles, thereby slowing down or even preventing the further spread of the fire. At the same time, this flame retardant gas protective layer not only has a cooling effect, which can reduce the temperature in the flame area, reduce heat radiation and heat convection, but also can interfere with the chain reaction of the flame, greatly slowing down the combustion speed of the flame or even completely extinguishing it. At the same time, due to the fast response speed of the overall device, the time from flame contact to flame retardant gas release is extremely short, which can greatly reduce the losses that may be caused in the initial stage of the fire. After the fire is initially controlled, the monitoring device inside the flame retardant gas storage 7090 will continuously detect the change of the fire situation. When there is a tendency of the fire to reignite, it can be immediately restarted to release more flame retardant gas to maintain effective suppression of the fire.

[0034] In the present invention, according to Figure 1 - Figure 5 As shown, a flame retardant inner core layer 4 is installed at the bottom end of the top aluminum plate mounting plate 3. A plurality of groups of carbon nanotubes 12 are inserted on the surface of the flame retardant inner core layer 4, and graphene connection high-strength rib strips 11 are tightly connected to the side ends of the plurality of groups of carbon nanotubes 12.

[0035] Multiple groups of carbon nanotubes 12 and graphene are connected to high-strength ribs 11 to form an integrated structure located inside the top aluminum plate mounting plate 3, and a waterproof and anti-corrosion layer is coated on the surface of the top aluminum plate mounting plate 3.

[0036] A high-flame-retardant seat 13 is installed inside multiple shape memory alloy grooves 10, and the high-flame-retardant seat 13 is located inside the multiple shape memory alloy grooves 10 to form a cavity structure.

[0037] The cavity is filled with magnesium hydroxide flame retardant. Installation aperture grooves are provided on the side surface of the high-flame-retardant seat 13, and reinforcing fixing ribs are inserted into the installation aperture grooves. The reinforcing fixing ribs are used to fix the top aluminum plate mounting plate 3 and the bottom aluminum plate mounting plate 2, and an installation gap exists between the top aluminum plate mounting plate 3 and the bottom aluminum plate mounting plate 2.

[0038] The bottom aluminum plate mounting plate 2 is installed at the bottom of the flame-retardant inner core layer 4, and a waterproof and moisture-resistant layer 5 is tightly connected to the bottom of the bottom aluminum plate mounting plate 2.

[0039] The fireproof layer 1 is composed of a fireproof coating and a dry layer board. The impact-resistant plate 8 is installed at the bottom of the fireproof layer 1, and the metal heat-conducting sheet is embedded inside the sandwich space between the fireproof layer 1 and the impact-resistant plate 8.

[0040] The edge-sealing metal frame 9 is installed at the bottom of the waterproof and moisture-resistant layer 5. The edge-sealing metal frame 9 is used to fix the metal heat-conducting sheet between the fireproof layer 1 and the impact-resistant plate 8, and multiple phase-change material connecting columns 6 are embedded and installed on the side of the edge-sealing metal frame 9.

[0041] In a specific solution, the overall aluminum-plastic composite panel consists of multiple key components, including a fireproof layer 1, a bottom aluminum plate mounting plate 2, a top aluminum plate mounting plate 3, a flame-retardant inner core layer 4, a waterproof and moisture-resistant layer 5, an impact-resistant plate 8, a sealing edge metal frame 9, and a high-load flame-retardant seat 13. First of all, the fireproof layer 1 is carefully composed of calcium silicate board and glass fiber, ensuring the excellent fireproof performance of the aluminum-plastic composite panel. The bottom aluminum plate mounting plate 2 and the top aluminum plate mounting plate 3 are respectively located at the bottom and top of the composite panel, providing strong support and protecting the flame-retardant inner core layer 4 and related internal structures. At the same time, a waterproof and anti-corrosion layer is coated on the surface of the top aluminum plate mounting plate 3, enabling the waterproof and anti-corrosion layer to effectively prevent the erosion of moisture and corrosive substances, thereby extending the service life of the material. With the cooperation of carbon nanotubes 12 and graphene-connected high-strength ribs 11, the flame-retardant inner core layer 4 improves the mechanical strength of the overall composite board and significantly enhances the flame-retardant performance. The setting of the high-load flame-retardant seat 13 forms a different temperature gradient layer with the flame-retardant inner core layer 4, ensuring different flame-retardant properties of the flame-retardant inner core layer 4, the bottom aluminum plate mounting plate 2, and the top aluminum plate mounting plate 3. In addition, the cavity of the high-load flame-retardant seat 13 is filled with magnesium hydroxide flame retardant, further enhancing the overall flame-retardant effect. The waterproof and moisture-resistant layer 5 is composed of polyurethane waterproof coating, which is located at the bottom of the bottom aluminum plate mounting plate 2 and can effectively prevent moisture penetration, protecting the internal structure from moisture. The impact-resistant plate 8 is composed of polycarbonate and glass fiber-reinforced plastic, making the aluminum-plastic composite panel more tolerant to impacts. The sealing edge metal frame 9 not only fixes the metal heat-conducting sheet, ensuring the smoothness of the heat conduction path, but also, through its stability, installs multiple groups of phase change material connecting columns 6 on the side of the sealing edge metal frame 9. The setting of multiple groups of phase change material connecting columns 6 enables a large amount of heat to be absorbed at high temperatures, thereby reducing the temperature of the four-end cross-section of the overall composite board and further improving the fireproof effect. The composition of the overall aluminum-plastic composite panel ensures its excellent performance in aspects such as fireproof, impact-resistant, waterproof, and moisture-resistant, making it an efficient and reliable building material. At the same time, between the high-load flame-retardant seat 13 and the flame-retardant inner core layer 4, a decorative texture film can be embedded, enriching the appearance effect of the board and, to a certain extent, increasing the wear resistance and scratch resistance of the board. When the aluminum-plastic composite panel is applied to indoor and outdoor decoration, it can not only show modern beauty but also maintain a long-lasting new appearance. In particular, the polyurethane waterproof coating selected for the waterproof and moisture-resistant layer 5 uses an environmentally friendly formula, ensuring harmlessness to the human body during construction and use, and also helping to reduce the impact on the environment. In terms of installation and maintenance, the design of the aluminum-plastic composite panel also reflects convenience. Standardized installation notches are provided at the edges of the bottom aluminum plate mounting plate 2 and the top aluminum plate mounting plate 3, which, in cooperation with special connectors, make the installation process fast and simple, greatly shortening the construction period. At the same time, the modular design adopted between layers enables a certain layer to be repaired or replaced without overall disassembly.The maintenance cost is reduced and the work efficiency is improved.

[0042] The wiring diagram of the flame retardant gas storage 7090 in the present invention belongs to the common knowledge in the art. Its working principle is already known technology. Its model is selected according to actual use. Therefore, the control method and wiring layout of the flame retardant gas storage 7090 will not be explained in detail.

[0043] Usage method and working principle of this device: First, the overall aluminum-plastic composite board consists of multiple key parts, including a fireproof layer 1, a bottom aluminum plate mounting plate 2, a top aluminum plate mounting plate 3, a flame-retardant inner core layer 4, a waterproof and moisture-resistant layer 5, an impact-resistant plate 8, a sealing edge metal frame 9, and a high-flame-retardant bearing seat 13. First of all, the fireproof layer 1 is carefully composed of calcium silicate board and glass fiber, ensuring excellent fireproof performance of the aluminum-plastic composite board. The bottom aluminum plate mounting plate 2 and the top aluminum plate mounting plate 3 are respectively located at the bottom and top of the composite board, providing strong support and protecting the flame-retardant inner core layer 4 and related internal structures. At the same time, a waterproof and anti-corrosion layer is coated on the surface of the top aluminum plate mounting plate 3, enabling the waterproof and anti-corrosion layer to effectively prevent the erosion of moisture and corrosive substances, thereby extending the service life of the material. With the cooperation of carbon nanotubes 12 and graphene-connected high-strength ribs 11, the flame-retardant inner core layer 4 improves the mechanical strength of the overall composite board and significantly enhances the flame-retardant performance. In addition, the cavity of the high-flame-retardant bearing seat 13 is filled with magnesium hydroxide flame retardant, further enhancing the overall flame-retardant effect. The waterproof and moisture-resistant layer 5 is composed of polyurethane waterproof coating. It is located at the bottom of the bottom aluminum plate mounting plate 2 and can effectively prevent moisture penetration, protecting the internal structure from being affected by moisture. The impact-resistant plate 8 is composed of polycarbonate and glass fiber-reinforced plastic, making the aluminum-plastic composite board more tolerant to impact. The sealing edge metal frame 9 not only fixes the metal heat-conducting sheet, ensuring the smoothness of the heat conduction path, but also, through its stability, installs multiple groups of phase change material connecting columns 6 on the side of the sealing edge metal frame 9. The setting of multiple groups of phase change material connecting columns 6 enables a large amount of heat to be absorbed at high temperatures, thereby reducing the temperature of the four-end cross-section of the overall composite board and further improving the fireproof effect. The composition of the overall aluminum-plastic composite board ensures its excellent performance in terms of fireproof, impact-resistant, waterproof, and moisture-resistant. Then, when a fire occurs, during a fire, the high temperature generated by the flame is first conducted to the heat conduction column contact column 706 through the metal heat-conducting sheet. This process is the first step of heat transfer. Subsequently, the heat conduction column contact column 706 transfers the received heat to the heat conduction metal conduction sheet 7098, further enhancing the heat transfer efficiency. Then, the heat is transferred to the fixed-line heat conduction end 7097 through the heat conduction metal conduction sheet 7098, causing the fixed-line heat conduction end 7097 to quickly heat up. The fixed-line heat conduction end 7097 continues to transfer the received heat to the polyethylene fracture node 7096. Since the melting point of the polyethylene material is relatively low, approximately between 120°C and 135°C, under the action of high temperature, the polyethylene fracture node 7096 will quickly melt and break. The fracture of the polyethylene fracture node 7096 causes the polypropylene fiber connection loop 7095 to lose its original supporting effect. The melting point of the polypropylene fiber connection loop 7095 is relatively high, approximately between 160°C and 170°C, but it will also quickly melt when it loses support. When the polypropylene fiber connection loop 7095 melts,The limiting hook 7094 is released under the action of the compressed elastic spring member 7092 and no longer restricts the needle-piercing trigger member 7091. Then, under the push of the compressed elastic spring member 7092, the needle-piercing trigger member 7091 quickly pierces the flame-retardant gas storage 7090, releasing the stored flame-retardant gas. Overall, this effectively improves the response speed and reliability of the operation. When a fire occurs, through this rapid heat transfer and material melting mechanism, the flame-retardant gas can be quickly and effectively released, thus playing a fire-prevention role, effectively preventing the spread of the fire, and ensuring people's life and property safety. Moreover, with the rapid release of the flame-retardant gas, it quickly diffuses around the flame, forming a protective layer that effectively isolates the contact between the flame and the surrounding combustibles, thereby slowing down or even preventing the further spread of the fire. At the same time, this generated flame-retardant gas protective layer not only has a cooling effect, which can reduce the temperature in the flame area, reduce heat radiation and heat convection, but also can interfere with the chain reaction of the flame, greatly slowing down the combustion speed of the flame or even completely extinguishing it. Meanwhile, due to the fast response speed of the overall device, the time from the flame contact to the release of the flame-retardant gas is extremely short, which can greatly reduce the losses that may be caused in the initial stage of the fire. After the fire is initially controlled, the monitoring device inside the flame-retardant gas storage 7090 continuously detects the change of the fire situation. When there is a tendency of the fire to reignite, it can be immediately restarted to release more flame-retardant gas to maintain effective suppression of the fire.
