[0018] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0019] The embodiment of the present application discloses a multi-layer furniture board with waterproof and flame retardant functions. Figures 1 to 3 The multi-layer furniture panel with waterproof and flame retardant functions includes an inner panel 10, a first middle layer 20, a second middle layer 30, a first outer panel 40, a second outer panel 50, and a protective frame 70. The inner panel 10 has two opposite sides bonded to the first middle layer 20 and the second middle layer 30 respectively; the opposite sides of the first middle layer 20 and the second middle layer 30 are bonded to the first outer panel 40 and the second outer panel 50 respectively, so that the inner panel 10, the first middle layer 20, the second middle layer 30, the first outer panel 40, and the second outer panel 50 form a composite multi-layer panel. A circle of gap is formed between the outer side surfaces of the first middle layer 20 and the second middle layer 30 and the outer side walls of the first outer layer plate 40 and the second outer layer plate 50. The protective frame 70 is filled in the gap, and the protective frame 70 is respectively bonded and fixed to the first outer layer plate 40 and the second outer layer plate 50, so that the aforementioned composite multi-layer plate forms a plate with a smooth outer edge.

[0020] In this embodiment, the inner layer plate 10 includes a first core plate 11, a second core plate 12 and a plurality of reinforcement tubes 13. The facing sides of the first core plate 11 and the second core plate 12 are formed with grooves equal to the number of reinforcement tubes 13, and each reinforcement tube 13 is embedded in the grooves on the surfaces of the first core plate 11 and the second core plate 12. The facing contact surfaces between the first core plate 11 and the second core plate 12 can be fixed by bonding with an adhesive, so that the plurality of reinforcement tubes 13 are clamped and fixed between the first core plate 11 and the second core plate 12. The length of the reinforcement tube 13 is adapted to the length of the first core plate 11 or the second core plate 12, and the reinforcement tube 13 can be made into a tubular shape by pre-impregnating a styrene-based polyester resin with carbon fiber composite material and then heating, curing, pultruding or winding. Carbon fiber tubes have the advantages of high strength, long life, corrosion resistance, light weight and low density. Arranging multiple reinforcement tubes 13 between the first core board 11 and the second core board 12 helps to strengthen the overall strength of the inner layer board 10 and can also reduce its bending deformation, so that the furniture board can be better used for load-bearing when used as furniture.

[0021] In this embodiment, both the first middle layer 20 and the second middle layer 30 can be made of PET flame retardant film, and when the first middle layer 20 and the second middle layer 30 are compounded on the outside of the inner layer plate 10, the first middle layer 20 and the second middle layer 30 can be adhered to the opposite two side surfaces of the inner layer plate 10, and the first middle layer 20 and the second middle layer 30 are extended to the part of the outer circle of the inner layer plate 10 and bent, and adhered and fixed to the outer wall of the inner layer plate 10, so that the inner layer plate 10 is covered as a whole by the first middle layer 20 and the second middle layer 30, so as to utilize the first middle layer 20 and the second middle layer 30 to provide flame retardant protection for the inner layer plate 10.

[0022] In this embodiment, the first outer panel 40, the second outer panel 50, and the protective frame 70 can all be made of moisture-proof panels, such as wood-plastic composite panels, PVC panels, or aluminum-plastic panels. These materials have good moisture-proof and water-resistant properties when used, and can also have a certain degree of corrosion resistance to chemicals such as seawater, grease, acid, and alkali, thereby extending the service life of the furniture panels.

[0023] In this embodiment, the four facing corners of the first and second outer panels 40, 50 are each formed with raised corner protectors 60. The outward-facing end of the corner protector 60 forms a convex angle, while the inward-facing end forms a concave angle. The concave corners of the corner protectors 60 allow the inner panel 10, coated with the first and second middle layers 20, 30, to be positioned during assembly by inserting its four corners into the concave corners of the corner protectors 60.

[0024] In this embodiment, the guard frame 70 may include four separate trapezoidal panels, each of which is positioned between two adjacent corner guards 60, and the inclined surfaces on both sides of the guard frame 70 are bonded to and secured to the outer walls of the corner guards 60. Furthermore, the side of the trapezoidal panel in the guard frame 70 facing the inner panel 10 is bonded to and secured to the outer side surfaces of the first middle layer 20 and the second middle layer 30, and the side of the guard frame 70 facing the first outer layer 40 or the second outer layer 50 is bonded to and secured to the first outer layer 40 or the second outer layer 50, thereby ensuring that each of the trapezoidal panels is securely connected.

[0025] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
