Technical Field
[0001] This utility model relates to the technical field of flame-retardant foam plastic boards, and in particular to a flame-retardant foam plastic board with a reinforced structure. Background Technology
[0002] Flame-retardant foam plastic board is a type of foam plastic board made of materials such as polystyrene and polypropylene. It has excellent flame-retardant properties, meaning it is not easily combustible in the event of a fire, and can effectively prevent fire accidents.
[0003] The existing lightweight foam plastic boards do not have a pressure-reducing layer, which reduces the compressive strength of the foam plastic board. After prolonged use, they will deform, resulting in a decrease in hardness. They will also easily deform even under light pressure from heavy objects, thus reducing the durability of the lightweight foam plastic boards. Furthermore, the existing lightweight foam plastic boards are not convenient for combination use, reducing their practicality.
[0004] An existing patent (publication number: CN217495452U) discloses a lightweight foam plastic board. The lightweight foam plastic board can improve the compressive strength of the foam plastic board by adding a pressure-reducing layer, thereby improving the durability of the lightweight foam plastic board. Furthermore, the added splicing blocks and splicing grooves allow users to combine the lightweight foam plastic board for use, thereby improving its practicality.
[0005] Existing patents offer solutions to the above problems, but they suffer from poor mechanical properties. When subjected to external forces, they are prone to cracking and deformation, affecting their service life and performance. In particular, when splicing, the joints often become the weakest points of the entire board, making it difficult to withstand large external forces and resulting in insufficient overall strength after splicing. At the same time, their surface protection performance also needs to be improved, as they are easily damaged by impacts during use, reducing the performance of the board.
[0006] To address this, a flame-retardant foam plastic board with a reinforced structure is proposed. Utility Model Content
[0007] The purpose of this utility model is to provide a flame-retardant foam plastic board with a reinforced structure, which can solve the problem of poor mechanical properties of existing foam plastic boards. When subjected to external forces, they are prone to cracking and deformation, affecting their service life and performance. Especially when splicing, the joints often become the weak points of the entire board, making it difficult to withstand large external forces, resulting in insufficient overall strength after splicing. At the same time, its surface protection performance also needs to be improved, as it is easily damaged by impacts during use, reducing the performance of the board.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant foam plastic board with a reinforced structure, comprising a foam plastic board body, wherein an I-shaped reinforcing member is pre-embedded inside the edge of the foam plastic board body, one end of the I-shaped reinforcing member is embedded inside the foam plastic board body, and the other end is exposed to form a connecting buckle, the foam plastic board body includes an upper surface layer and a lower surface layer, a reinforcing layer is provided on the opposite side of the upper surface layer and the lower surface layer, and an intermediate core layer is provided between the opposite sides of the two reinforcing layers, and a functional layer is provided on the surface of the upper surface layer and the lower surface layer;
[0009] The intermediate core layer includes two connecting layers, and a three-dimensional reinforcement structure is provided between the two connecting layers.
[0010] Preferably, the functional layer includes an impact-resistant layer, and a flame-retardant reinforcing layer is provided on the side of the impact-resistant layer away from the upper and lower surfaces, respectively.
[0011] Preferably, the impact-resistant layer is made of elastic polyurethane material.
[0012] Preferably, the flame-retardant reinforcing layer is composed of a halogen-free flame-retardant coating.
[0013] Preferably, the reinforcing layer is composed of a glass fiber mesh.
[0014] Preferably, the upper surface layer, reinforcing layer, intermediate core layer and lower surface layer are bonded together by flame-retardant adhesive.
[0015] Preferably, the connecting layer is composed of low-density foam, and its density is 20%-30% lower than that of the upper and lower surface layers.
[0016] Preferably, the three-dimensional reinforcement structure is composed of flame-retardant glass fiber reinforced plastic strips and is arranged in a honeycomb pattern.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This application uses a composite reinforcing layer, a core layer, and a functional layer in the main body of the foam plastic board. Under the action of the reinforcing layer, it can effectively disperse external forces and bear part of the stress when subjected to external pressure, tension, etc., preventing the board from cracking and deforming, and significantly improving the overall mechanical properties of the foam plastic board. The core layer enables the entire foam plastic board to have excellent compression resistance and deformation resistance on the basis of good buffering performance, improving the comprehensive performance and use effect of the board. Through the functional layer, it can undergo large elastic deformation when subjected to impact, absorb impact energy, and thus effectively protect the main body of the foam plastic board from impact damage, significantly improving the impact resistance of the board.
[0019] 2. This application incorporates I-beam reinforcements. The I-beam structure provides high bending strength and stability, effectively enhancing the mechanical properties of the foam board edges and preventing damage when subjected to external forces. The exposed connecting clips offer a convenient and robust connection method for splicing the foam boards. During splicing, the connecting clips of adjacent boards cooperate with each other. Compared to traditional splicing methods, this connection method allows the splice to withstand greater external forces, effectively solving the problem of insufficient overall strength after splicing. This significantly improves the stability and reliability of the spliced structure, enabling multiple foam boards to form a solid whole, expanding the application range of foam boards and enhancing their practicality.

Detailed Implementation
[0026] 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.
[0027] Please see Figure 1-5 The present invention provides the following technical solution:
[0028] A flame-retardant foam plastic board with a reinforced structure includes a foam plastic board body 1. An I-shaped reinforcing member 2 is pre-embedded inside the edge of the foam plastic board body 1. One end of the I-shaped reinforcing member 2 is embedded inside the foam plastic board body 1, and the other end is exposed to form a connecting buckle. The foam plastic board body 1 includes an upper surface layer 3 and a lower surface layer 4. A reinforcing layer 5 is provided on the opposite side of the upper surface layer 3 and the lower surface layer 4, and an intermediate core layer 6 is provided between the opposite sides of the two reinforcing layers 5. A functional layer 7 is provided on the surface of the upper surface layer 3 and the lower surface layer 4.
[0029] The intermediate core layer 6 includes two connecting layers 61, and a three-dimensional reinforcement structure 62 is provided between the two connecting layers 61.
[0030] In this embodiment: the foam plastic board body 1 is composite with a reinforcing layer 5, a core layer 6, and a functional layer 7. Under the action of the reinforcing layer 5, external forces can be effectively dispersed. When subjected to external pressure, tension, etc., it can bear part of the stress, preventing the board from cracking and deforming, and significantly improving the overall mechanical properties of the foam plastic board body 1. The core layer 6 enables the entire foam plastic board body 1 to have excellent compression resistance and deformation resistance on the basis of good buffering performance, improving the comprehensive performance and use effect of the board. Through the functional layer 7, it can undergo large elastic deformation when subjected to impact, absorbing impact energy, thereby effectively protecting the foam plastic board body 1 from impact damage and significantly improving the impact resistance of the board. By setting an I-beam shape The reinforcing component 2, with its I-beam structure, possesses high bending strength and stability, effectively enhancing the mechanical properties of the edges of the foam plastic board body 1 and preventing damage to the edges under external forces. The exposed connecting clips provide a convenient and robust connection method for splicing the foam plastic board body 1. During splicing, the connecting clips of adjacent boards cooperate with each other. Compared to traditional splicing methods, this connection method allows the spliced joint to withstand greater external forces, effectively solving the problem of insufficient overall strength after splicing. This significantly improves the stability and reliability of the spliced joint, enabling multiple foam plastic board bodies 1 to form a solid whole, expanding the application range of the foam plastic board body 1 and enhancing its practicality.
[0031] Specifically, such as Figure 5 As shown, the functional layer 7 includes an impact-resistant layer 71, and a flame-retardant reinforcing layer 72 is provided on the side of the impact-resistant layer 71 away from the upper surface layer 3 and the lower surface layer 4.
[0032] Specifically, such as Figure 5 As shown, the impact-resistant layer 71 is made of elastic polyurethane material.
[0033] Specifically, such as Figure 5 As shown, the flame-retardant reinforcing layer 72 is composed of a halogen-free flame-retardant coating.
[0034] In this embodiment: the impact-resistant layer 71 is made of elastic polyurethane material. The properties of elastic polyurethane material can effectively absorb impact energy, making the impact resistance of the foam plastic board body 1 more prominent and providing more reliable protection for the board. The flame-retardant reinforcing layer 72 is made of halogen-free flame-retardant coating. The use of halogen-free flame-retardant coating not only enhances the flame-retardant performance of the foam plastic board body 1, but also meets environmental protection requirements. Compared with traditional flame-retardant materials, it reduces the harm to the environment and human body while ensuring fire safety, and enhances the environmental advantages and market competitiveness of the board.
[0035] Specifically, such as Figure 3 As shown, the reinforcing layer 5 is composed of a glass fiber mesh.
[0036] Specifically, such as Figure 3 As shown, the upper surface layer 3, the reinforcing layer 5, the intermediate core layer 6, and the lower surface layer 4 are bonded together with flame-retardant adhesive.
[0037] In this embodiment: the reinforcing layer 5 is made of fiberglass mesh. The high strength and high modulus of the fiberglass mesh enable the reinforcing layer 5 to effectively disperse external forces, improve the overall mechanical properties of the foam board body 1, and make the board more stable and reliable when subjected to external forces. The upper surface layer 3, the reinforcing layer 5, the middle core layer 6, and the lower surface layer 4 are bonded together with flame-retardant adhesive. The use of flame-retardant adhesive not only ensures the connection strength between each layer and makes the board structure more stable, but also further enhances the flame-retardant performance of the board, ensuring that the layers will not easily separate in the event of a fire, thus improving the safety of the board in a fire.
[0038] Specifically, such as Figure 4 As shown, the connecting layer 61 is made of low-density foam, and its density is 20%-30% lower than that of the upper surface layer 3 and the lower surface layer 4.
[0039] Specifically, such as Figure 4 As shown, the three-dimensional reinforcement structure 62 is composed of flame-retardant glass fiber reinforced plastic strips and is arranged in a honeycomb pattern.
[0040] In this embodiment: the connecting layer 61 is made of low-density foam, and its density is 20%-30% lower than that of the upper surface layer 3 and the lower surface layer 4. The low-density connecting layer 61 gives the middle core layer 6 good cushioning performance. At the same time, it works in conjunction with the honeycomb-shaped three-dimensional reinforcement structure 62, so that the middle core layer 6 has high compressive strength on the basis of having cushioning ability.
[0041] Working principle: During the splicing and installation of the foam plastic board body 1, one end of the I-shaped reinforcement 2 is embedded into the foam plastic board body 1, and the other end is exposed to form a connecting buckle. During splicing, the buckle precisely matches the groove of the adjacent board, avoiding the joint from becoming a weak point. When the foam plastic board body 1 is in use, the reinforcement layer 5 can bear part of the stress when subjected to external pressure, tension, etc., preventing the board from cracking and deforming, and significantly improving the overall mechanical properties of the foam plastic board body 1. The middle core layer 6 enables the entire foam plastic board body 1 to have excellent compression resistance and deformation resistance on the basis of good cushioning performance, improving the comprehensive performance and use effect of the board. Through the functional layer 7, it can undergo large elastic deformation when subjected to impact, absorbing impact energy, thereby effectively protecting the foam plastic board body 1 from impact damage and significantly improving the impact resistance of the board.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
