Description

Technical Field

[0001] This utility model relates to the field of multilayer board technology, specifically a flame-retardant multilayer board. Background Technology

[0002] Flame-retardant plywood (also known as flame-retardant plywood or fire-resistant plywood) is a functional board material that combines fire resistance and structural strength. It is made by adding flame retardants or pressing flame-retardant treated veneers onto ordinary plywood. It is mainly used for wall bases, furniture and decorative materials in commercial spaces (such as shopping malls and office buildings) and must meet the requirements of fire protection codes for Class B1 fire-resistant materials.

[0003] While existing flame-retardant multilayer boards have good flame-retardant effects, considering that the boards may be used in humid environments in some cases, the flame retardants in the boards easily absorb moisture over time, leading to an increase in the internal moisture content of the boards. This affects the dimensional stability and mechanical properties of the boards, causing the boards to gradually deteriorate in humid environments and shorten their service life. Therefore, a flame-retardant multilayer board is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a flame-retardant multilayer board to solve the problems mentioned in the background art, such as the easy absorption of moisture, gradual deterioration of stability, and shortened service life of existing flame-retardant multilayer boards when used in humid environments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A flame-retardant multilayer board includes a substrate layer, a waterproof thin film layer bonded to the top surface of the substrate layer, a lower mesh fabric covering the top of the waterproof thin film layer, a flame retardant layer covering the top of the lower mesh fabric, a net fabric covering the top of the flame retardant layer, a moisture-proof pad bonded to the top of the net fabric, an outer panel bonded to the top of the moisture-proof pad, and a superhydrophilic nano-coating coated on the top surface of the outer panel.

[0006] Preferably, the bottom of the substrate layer is provided with a bottom layer, and the bottom surface of the substrate layer is provided with an anti-slip texture structure.

[0007] Preferably, the waterproof thin film layer and the lower mesh fabric are bonded together, and the thickness of the lower mesh fabric is the same as the thickness of the upper mesh fabric.

[0008] Preferably, the flame retardant layer is bonded to the lower mesh and the upper mesh by internally interwoven phenolic resin.

[0009] Preferably, the thickness of the outer panel is greater than the thickness of the superhydrophilic nanocoating.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the inclusion of a waterproof thin film layer, a lower mesh fabric, a top mesh fabric, a moisture-proof pad, and a super-hydrophilic nano-coating facilitates the use of the flame-retardant multilayer board in humid environments. With efficient composite processing in the workshop, a waterproof and moisture-proof structure composed of this layer can be added to the board. Unlike conventional boards containing flame retardants, this board mitigates the impact of external environmental factors, exhibiting excellent waterproof and moisture-proof performance. It also enhances the board's mechanical properties and structural stability, preventing the flame retardants from absorbing moisture and increasing the internal moisture content of the board in special environments. Furthermore, it prevents the board's stability from gradually deteriorating in humid environments, extending its service life. Attached Figure Description

[0013] 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.

[0014] Please see Figure 1-3 This utility model provides a technical solution: A flame-retardant multilayer board includes a substrate layer 1, a waterproof thin film layer 2 bonded to the top surface of the substrate layer 1, a lower mesh fabric 3 covering the top of the waterproof thin film layer 2, a flame retardant layer 4 covering the top of the lower mesh fabric 3, a mesh fabric 5 covering the top of the flame retardant layer 4, a moisture-proof pad 6 bonded to the top of the mesh fabric 5, an outer panel 7 bonded to the top of the moisture-proof pad 6, and a super-hydrophilic nano-coating 8 coating the top surface of the outer panel 7.

[0015] The bottom of the substrate layer 1 is provided with a bottom layer 9, and the bottom surface of the substrate layer 1 is provided with an anti-slip texture structure. This structure provides a certain anti-slip feature when the board is laid flat for processing and use. The waterproof thin film layer 2 and the lower mesh 3 are bonded together, and the thickness of the lower mesh 3 is the same as that of the upper mesh 5. The flame retardant layer 4 is bonded to the lower mesh 3 and the upper mesh 5 respectively by internally doped phenolic resin. The upper and lower mesh boards are made of glass fiber and are bonded to the flame retardant layer 4 to form a three-layer structure, which can improve the structural stability of the flame retardant layer 4 after its formation and prevent the flame retardant material in the flame retardant layer 4 from spreading due to moisture. The thickness of the outer panel 7 is greater than the thickness of the superhydrophilic nano coating 8. The outer coating of the superhydrophilic nano coating 8 directly improves the waterproof and moisture-proof effect of the outer surface of the board.

[0016] Workflow: In the production workshop, when using composite work sections for board production, after the substrate layer 1 and the bottom layer 9 form a double-layer structure, the waterproof thin film layer 2 is bonded to the substrate layer 1. Then, the lower mesh fabric 3 is laid on the waterproof thin film layer 2, followed by the even application of an appropriate amount of flame-retardant material mixed with phenolic resin onto the lower mesh fabric 3. Next, the upper mesh fabric 5 is laid on top of the flame-retardant layer 4 formed by the appropriate amount of flame-retardant material, creating a three-layer structure. Then, the PVC moisture-proof pad 6 is bonded to the upper mesh fabric 5. Finally, after laying the outer panel 7, an appropriate amount of superhydrophilic nanomaterial is applied to the surface of the outer panel 7, forming a superhydrophilic nano-coating 8. The composite processing of the entire board is completed. When the board is in a damp environment facing downwards, the board can effectively improve the moisture and water resistance in actual use through the waterproof and moisture-proof structure composed of a waterproof thin film layer 2, a lower mesh cloth 3, a top mesh cloth 5, a moisture-proof pad 6 and a super-hydrophilic nano coating 8, reduce the impact of external environmental factors on the board, and also enhance the mechanical properties and structural stability of the board.
