Description

Technical Field

[0001] This utility model relates to the field of composite fiberboard design technology, and in particular to a durable and corrosion-resistant composite fiberboard. Background Technology

[0002] Composite fiberboard is a synthetic material composed of fibers and resins. It forms a thin, flat board and falls under the category of artificial wood products. It has the advantages of low price and durability. It can be used to make walls and has a good sound insulation effect. Most existing composite fiberboard structures consist of a middle substrate layer and two fiber reinforcement layers bonded to both sides. The middle substrate is mostly made of resin mixed with other fibers, while the fiber reinforcement layers are mostly made of environmentally friendly materials such as carbon fiber or bamboo fiber. Therefore, composite fiberboard is a composite board with excellent environmental protection properties.

[0003] Research revealed that existing composite panel designs are relatively simple. While the base layer and fiber reinforcement layers on both sides give the composite panel a certain strength, it is still susceptible to severe damage such as bending and cracking when used as a soundproof wall, especially if subjected to external impacts. This can shorten the lifespan of the wall. Furthermore, composite panels lack adequate external protection, making them prone to collisions during transportation, which can damage the adhesive, leading to unstable layer connections and even fiber reinforcement layer detachment. Although the fiber reinforcement layer provides corrosion resistance, its durability is significantly reduced in dusty or humid environments.

[0004] Therefore, it is necessary for the applicant to propose a durable and corrosion-resistant composite fiberboard to solve the problem. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a durable and corrosion-resistant composite fiberboard, including a board body, an outer protective frame, a substrate layer and a fiber layer, the fiber layer having two layers and being bonded to both sides of the substrate layer, both sides of the substrate layer having integrally connected raised strips with a grid-like appearance, and reinforcing mesh plates of the same grid-like appearance being fitted onto the outside of the raised strips, the bonding surface between the fiber layer and the substrate layer having grid-like grooves for embedding the reinforcing mesh plates, the inner wall of the protective frame being bonded to the substrate layer and the fiber layer, and the substrate layer and fiber layer of the protective frame, the outer surface of the fiber layer and both sides of the protective frame having corrosion-resistant layers.

[0007] Preferably, the edges and corners of the reinforcing mesh and the convex strip are all arc-shaped, and the inner corners of the mesh-shaped grooves are also arc-shaped to match the reinforcing mesh.

[0008] Preferably, the reinforced mesh plate is made of aluminum, and both the inner and outer surfaces of the reinforced mesh plate are provided with a zinc plating layer.

[0009] Preferably, the corrosion-resistant layer includes a waterproof layer and a wear-resistant layer. The wear-resistant layer is sprayed onto the outer surface of the fiber layer and the protective frame and is made of aluminum oxide. The waterproof layer is sprayed onto the surface of the wear-resistant layer and is made of polyurethane.

[0010] Preferably, the protective frame is made of two U-shaped frame plates spliced ​​together, and the protective frame is provided with slots and slide grooves.

[0015] 2. This utility model designs a protective frame. During installation, two U-shaped frame plates are inserted from both ends of the panel and fitted together to form the protective frame. At this time, the insert blocks are inserted into the slots, and the insert plates are slidably inserted into the slide grooves. Finally, the protective frame is fixedly connected to the insert blocks and insert plates on the substrate layer by screws to complete the installation. This results in a high connection strength between the protective frame and the panel, making the panel less prone to damage during transportation and improving the overall protective effect.

[0016] 3. Through the design of the corrosion-resistant layer and the wear-resistant layer, the wear resistance of the protective frame and the fiber layer surface is greatly improved, which can prevent the fiber layer from losing its corrosion resistance due to damage. At the same time, the waterproof layer enhances the waterproof effect and further improves the corrosion resistance of the board. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Depend on Figures 1-8The present invention provides a durable and corrosion-resistant composite fiberboard, comprising a board body 1, with a protective frame 2 covering the outside of the board body 1. The board body 1 includes a substrate layer 11 and a fiber layer 12. The fiber layer 12 has two layers and is bonded to both sides of the substrate layer 11. Both sides of the substrate layer 11 are integrally connected with protruding strips 13 in a grid-like appearance. Reinforcing mesh plates 14, which are also grid-like and compatible, are engaged with the protruding strips 13. The bonding surface between the fiber layer 12 and the substrate layer 11 is provided with grid-like grooves 15 for embedding the reinforcing mesh plates 14. The inner wall of the protective frame 2 is bonded to the substrate layer 11 and the fiber layer 12. The substrate layer 11 and the fiber layer 12 of the protective frame 2, the outer surface of the fiber layer 12, and both sides of the protective frame 2 are provided with corrosion-resistant layers.

[0028] As described above, by designing the convex strip 13, the reinforcing mesh plate 14, and the grid-like groove 15, during splicing, glue is applied to one side of the substrate layer 11, and glue is also applied to the surface of the convex strip 13. Then, the reinforcing mesh plate 14 is snapped onto the outer wall of the convex strip 13, at which point the reinforcing mesh plate 14 and the convex strip 13 are bonded together. Then, glue is applied to the surface of the reinforcing mesh plate 14, and then the fiber layer 12 is spliced ​​together with the substrate layer 11 to form a bond. At this point, the reinforcing mesh plate 14 is snapped into the grid-like groove 15. Then, the other side is spliced ​​in the same way to complete the assembly of the plate body 1. At this point, the metal reinforcing mesh plate 14 makes the overall strength of the plate body 1 higher. At the same time, the reinforcing mesh plate 14 is a clever thin sheet design, which can effectively avoid increasing the overall weight too much. When the two sides of the plate body 1 are impacted, the impact resistance can be enhanced by the reinforcing mesh plate 14, thereby effectively improving the service life of the plate body 1. It should be noted that the concave design at the bottom of the reinforcing mesh plate 14 is an existing design method.

[0029] The edges and corners of the reinforced mesh plate 14 and the raised strip 13 are all curved, and the inner corners of the mesh groove 15 are also curved to match the reinforced mesh plate 14. The reinforced mesh plate 14 is made of aluminum and has a galvanized layer on both the inner and outer surfaces.

[0030] As mentioned above, in the optimized design of the reinforced mesh plate 14, the use of aluminum metal provides excellent strength, while the zinc plating layer makes the aluminum metal less susceptible to corrosion on both the inside and outside, making the reinforced mesh plate 14 less prone to corrosion when in contact with adhesive. At the same time, the curved surface design allows for better fit with the mesh grooves 15 and the raised strips 13, making it very practical.

[0031] The corrosion-resistant layer includes a waterproof layer 122 and a wear-resistant layer 121. The wear-resistant layer 121 is sprayed on the outer surface of the fiber layer 12 and the protective frame 2 and is made of aluminum oxide. The waterproof layer 122 is sprayed on the surface of the wear-resistant layer 121 and is made of polyurethane.

[0032] As described above, through the design of the corrosion-resistant layer, the wear-resistant layer 121 greatly improves the wear resistance of the protective frame 2 and the fiber layer 12, which can prevent the fiber layer 12 from losing its corrosion resistance due to damage. At the same time, the waterproof layer 122 enhances the waterproof effect and further improves the corrosion resistance of the plate 1. It should be noted that the protective frame 2 and the fiber layer 12 are made of the same material.

[0033] The protective frame 2 is composed of two U-shaped frame plates spliced ​​together. The protective frame 2 is provided with slots 21 and slide grooves 22. One side of the slide groove 22 is open. Insert blocks 16 are fixed on both sides of the substrate layer 11 and the fiber layer 12, and insert plates 17 are fixed on the other two sides of the substrate layer 11 and the fiber layer 12. Insert blocks 16 can be inserted into slots 21, and insert plates 17 can be slidably inserted into the opening of the slide groove 22. Insert blocks 16 and insert plates 17 on the substrate layer 11 are provided with screw holes, and the protective frame 2 is provided with corresponding bolt holes. The protective frame 2, insert blocks 16 and insert plates 17 are fixedly connected by screws 23 inserted through bolt holes. The head of the screw 23 is cylindrical, and the head of the screw 23 fits against the inner wall of the circular hole of the protective frame 2, and the head of the screw 23 is aligned with the surface of the protective frame 2.

[0034] As described above, during the installation of the protective frame 2, two U-shaped frame plates are inserted and snapped into place from both ends of the plate 1. The two U-shapes are then joined together to form the protective frame 2. At this time, the insert 16 is inserted into the slot 21, and the insert plate 17 is slidably inserted into the slide groove 22. Finally, the protective frame 2 is fixedly connected to the insert 16 and insert plate 17 on the substrate layer 11 by screws 23 to complete the installation. This results in a high connection strength between the protective frame 2 and the plate 1, making the plate 1 less prone to damage during transportation and improving the overall protective effect.
