The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a corrosion-resistant film-covered plate, such as Figure 1-4 As shown, the corrosion-resistant laminated board includes: a laminated board body 1, which is composed of the following layered structure: an inner metal plate 2, which serves as the basic structure of the laminated board; a first adhesive layer 3, which is arranged on the top and bottom surfaces of the inner metal plate 2; a heat insulation layer 4, which is arranged on the first adhesive layer 3; a second adhesive layer 5, which is arranged on the heat insulation layer 4; a water-proof layer 6, which is arranged on the second adhesive layer 5 for preventing moisture from penetrating; a third adhesive layer 7, which is arranged on the water-proof layer 6; an outer metal plate 8, which is arranged on the third adhesive layer 7; a fourth adhesive layer 9, which is arranged on the outer metal plate 8 for being tightly connected with the corrosion-resistant film layer 10; the corrosion-resistant film layer 10, which is arranged on the fourth adhesive layer 9 for providing corrosion protection; a frame 11, which is arranged on the laminated board body 1.

[0022] It should be noted that with the continuous development of the construction industry, the requirements for building materials are also constantly increasing; traditional composite film-faced boards have been widely used in the construction field because of their multiple functions such as heat insulation, fire prevention and sound insulation. However, under specific environmental conditions, especially those environments with extremely high requirements for material corrosion resistance, such as the seaside and chemical plants, the performance of traditional composite film-faced boards faces severe challenges; in the seaside environment, due to the large amount of salt and moisture factors in the air, these substances will react chemically with the metal surface, causing the metal outer layer to gradually corrode. This corrosion process will not only reduce the appearance quality of the board, but more importantly, it will also weaken the structural strength of the board, thereby affecting its service life and overall performance; similarly, in environments such as chemical plants, due to the presence of a large amount of chemical gases and liquids, these substances are often highly corrosive. Traditional composite film-faced boards are easily damaged by chemical corrosion in such an environment, and their metal outer layer may suffer from severe corrosion in a short period of time, causing the performance of the board to rapidly decline, or even be unable to be used normally; therefore, in order to meet the construction industry's demand for high-performance building materials, especially the application needs in special environments, it is necessary to develop a new type of corrosion-resistant film-faced board to solve the above problems;

[0023] In this embodiment, the inner metal plate 2 serves as the basic structure of the film-coated board, and the inner metal plate 2 provides the main support and strength of the board; the first adhesive layer 3 is arranged on the top and bottom surfaces of the inner metal plate 2 to ensure a tight connection between the subsequent layers and the inner metal plate 2; the thermal insulation layer 4 is located on the first adhesive layer 3, which plays a thermal insulation role, reduces heat transfer, and improves the thermal insulation performance of the board; the second adhesive layer 5 is arranged on the thermal insulation layer 4 to ensure a firm connection between the waterproof layer 6 and the thermal insulation layer 4; the waterproof layer 6 is located on the second adhesive layer 5 to prevent moisture penetration and protect the internal layered structure from moisture; the third adhesive layer 7 is arranged on the waterproof layer 6 to provide a stable connection basis for the outer metal plate 8; the outer metal As the outer structure of the film-coated board, the plate 8, in addition to providing additional strength and protection, also forms the first line of defense against corrosion together with the corrosion-resistant film layer 10; the fourth adhesive layer 9 ensures the close connection between the corrosion-resistant film layer 10 and the outer metal plate 8, ensuring the durability of the anti-corrosion effect; the corrosion-resistant film layer 10 is a key part of the film-coated board, made of high-performance corrosion-resistant materials such as polytetrafluoroethylene (PTFE), which can resist chemical corrosion and salt erosion, greatly extending the service life of the board; the frame 11 is set on the outside of the film-coated board body 1, which plays a role in reinforcement and decoration, and also provides additional protection for the board; in the seaside environment, the salt and humidity factors contained in the air often cause corrosion on the metal surface. However, since the outer layer of the anti-corrosion film-coated board has a corrosion-resistant film layer 10, it can effectively resist the invasion of these corrosion factors and maintain the integrity and aesthetics of the board; in environments such as chemical plants, a large amount of chemical gases and liquids are highly corrosive. The corrosion-resistant film layer 10 can also resist these chemical corrosions, ensuring that the board can maintain stable performance in harsh environments; the design of the thermal insulation layer 4 and the waterproof layer 6 makes the corrosion-resistant film-coated board not only have excellent corrosion resistance, but also have heat insulation and waterproof functions, further improving the comprehensive performance of the board.

[0024] In a further preferred embodiment of the utility model, the frame 11 includes: a first frame body 12 and a second frame body 13 that can be spliced; a plug-in block 14 fixed on the second frame body 13; a plug-in slot 15 opened on the first frame body 12, and the plug-in slot 15 is adapted to the plug-in block 14; a pin 16 arranged on the first frame body 12 for limiting the plug-in block 14, and the bottom end of the pin 16 is threaded through the plug-in block 14.

[0025] In this embodiment, the design of the frame 11 fully considers the convenience of installation and disassembly, as well as the stability of the structure; the first frame 12 and the second frame 13 that can be spliced: the frame 11 is composed of two spliced ​​frames, namely the first frame 12 and the second frame 13. This design allows the frame 11 to be adjusted and spliced ​​according to the actual size of the laminate body 1, which increases the flexibility and adaptability of the frame; the plug-in block 14 is fixed on the second frame 13, and its function is to cooperate with the plug-in slot 15 on the first frame 12 to achieve a fast and stable connection between the two frames; the plug-in slot 15 is provided on the first frame 12, and its shape and size are adapted to the plug-in block 14. When the plug-in block 14 is inserted into the plug-in slot 15, a stable connection structure is formed between the two frames; the pin 16 is provided on the first frame 12, and is used to limit the plug-in block 14. The bottom end of the pin 16 penetrates the plug-in block 14 through a thread, thereby further enhancing the connection stability between the two frames; through the cooperation of the plug-in block 14 and the plug-in slot 15, and the limiting effect of the pin 16, the two frames of the frame 11 can be quickly and accurately spliced ​​together, greatly improving the installation efficiency; the close cooperation between the plug-in block 14 and the plug-in slot 15, and the threaded penetration of the pin 16 make the structure of the frame 11 very stable, able to withstand large external force impacts, and protect the laminated board body 1 from damage; since the frame 11 adopts a splicable design, the size and shape of the frame can be adjusted according to different needs to make it adapt to laminated board bodies 1 of different specifications and shapes, thereby increasing the versatility and practicality of the product.

[0026] In a further preferred embodiment of the present invention, the inner metal plate 2 and the outer metal plate 8 are made of aluminum alloy, and the first adhesive layer 3, the second adhesive layer 5 and the third adhesive layer 7 are all polymer adhesives.

[0027] In this embodiment, the inner metal plate 2, the outer metal plate 8 and the adhesive layer material in the main body 1 of the laminated board are specifically selected and optimized; the inner metal plate 2 and the outer metal plate 8: these two metal plates are made of aluminum alloy. Aluminum alloy has been widely used in the construction industry due to its advantages such as light weight, high strength, corrosion resistance and easy processing. As the basic structure and outer structure of the laminated board, the aluminum alloy material can effectively ensure the overall strength of the laminated board, while resisting a certain degree of corrosion and improving the service life of the board; the first adhesive layer 3, the second adhesive layer 5 and the third adhesive layer 7: these adhesive layers are all made of polymer adhesives. Polymer adhesives have excellent bonding properties and can tightly connect the various layers of materials together to form a whole. At the same time, the polymer adhesive also has good weather resistance and corrosion resistance, and can maintain stable performance in various environments, ensuring the long-term use of the laminated board; the inner metal plate 2 and the outer metal plate 8 made of aluminum alloy make the laminated board reduce the overall weight while maintaining sufficient strength, which is convenient for transportation and installation; the aluminum alloy material itself has a certain corrosion resistance, combined with the corrosion resistance of the polymer adhesive, the laminated board can still maintain stable performance in harsh environments such as the seaside and chemical plants, and extend its service life; the polymer adhesive has excellent bonding properties, and can tightly connect the various layers of materials together to form a whole, ensuring the stability and reliability of the laminated board; due to the use of aluminum alloy and polymer adhesive, the laminated board can adapt to different environments and application requirements, improving the versatility and practicality of the product.

[0028] In a further preferred embodiment of the present invention, the heat insulation layer 4 is a ceramic fiber material board, the waterproof layer 6 is a high-density polyethylene film, the thickness of the ceramic fiber material board is 5 to 15 mm, and the thickness of the high-density polyethylene film is 0.1 to 0.5 mm.

[0029] In this embodiment, the material and thickness of the heat-insulating layer 4 and the waterproof layer 6 are specifically selected and optimized; the heat-insulating layer 4 uses a ceramic fiber material board as the heat-insulating layer. Ceramic fiber materials have excellent high-temperature resistance and heat-insulating properties, good chemical stability, and are not easily corroded. In this embodiment, the thickness of the ceramic fiber material board is set to 5 to 15 mm. This thickness range not only ensures sufficient heat-insulating effect, but also takes into account the balance between cost and weight; the waterproof layer 6 uses a high-density polyethylene film as the waterproof layer. The high-density polyethylene film has excellent waterproof properties, can effectively prevent moisture penetration, and protect the internal layered structure from moisture. Its thickness is set to 0.1 to 0.5 mm, which not only ensures the waterproof effect, but also ensures sufficient flexibility and weather resistance.

[0030] In a further preferred embodiment of the present invention, the corrosion-resistant film layer 10 is a polytetrafluoroethylene film, and the thickness of the polytetrafluoroethylene film is 0.01 to 0.1 mm.

[0031] In this embodiment, the material and thickness of the corrosion-resistant film layer 10 are specifically selected and optimized; the corrosion-resistant film layer 10 uses a polytetrafluoroethylene (PTFE) film as the corrosion-resistant film layer. Polytetrafluoroethylene is a material with excellent corrosion resistance and can resist erosion by a variety of chemical substances, including strong acids, strong alkalis, organic solvents, etc. At the same time, polytetrafluoroethylene also has good high and low temperature resistance, as well as low friction coefficient and non-adhesion; the thickness of the polytetrafluoroethylene film is set to 0.01 to 0.1 mm. This thickness range ensures sufficient corrosion resistance and the flexibility and weather resistance of the film layer. A thinner film layer can reduce the amount of material used and reduce costs, while a thicker film layer can provide better corrosion protection.

[0032] In a further preferred embodiment of the present invention, a sealing layer is disposed on the inner walls of the first frame 12 and the second frame 13, and the thickness of the sealing layer is 0.5 to 2 mm.

[0033] In this embodiment, the inner walls of the first frame 12 and the second frame 13 are specially designed, that is, a sealant layer is provided; a sealant layer is provided on the inner walls of the first frame 12 and the second frame 13. The main function of the sealant layer is to provide additional sealing performance, to ensure that the connection between the frame 11 and the inner metal plate 2 and the outer metal plate 8 can fit tightly, and to prevent the intrusion of external factors such as moisture and dust; the thickness of the sealant layer is set to 0.5 to 2 mm. The selection of this thickness range is based on the balance between sealing effect and cost. A thinner sealant layer may not provide sufficient sealing performance, while a thicker sealant layer may increase the cost and reduce the flexibility of the frame. Therefore, the thickness range of 0.5 to 2 mm can ensure that the flexibility and economy of the frame are maintained while maintaining good sealing performance.

[0034] In a further preferred embodiment of the present invention, both the first frame 12 and the plug-in block 14 are provided with assembly holes, and the assembly holes are adapted to the pins 16 .

[0035] In this embodiment, the design of the first frame 12 and the plug-in block 14 is optimized, that is, assembly holes are opened on them, and these assembly holes are compatible with the pins 16; assembly holes are opened on the first frame 12 and the plug-in block 14; the shapes, sizes and positions of these assembly holes are carefully designed to ensure that the pins 16 can be smoothly and accurately inserted into them, so as to limit and fix the plug-in block 14 on the first frame 12.

[0036] In summary, the corrosion-resistant film-faced panels provided by this technical solution, through multi-level material selection and structural design, effectively solve the problem of insufficient corrosion resistance of traditional composite film-faced panels in specific environments, improve the durability and reliability of building materials, and meet the construction industry's demand for high-performance building materials.
