The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0023] Reference Figure 1-3 The embodiment of the present invention provides a reinforcement structure of formaldehyde-free coated plywood, which includes two adjacent base boards 1, the two base boards 1 are fixedly connected to a connecting plate 2 on the opposite sides thereof, and the two connecting plates 2 are provided with a mortise and tenon groove 5 inside the opposite sides thereof, and two mortises 6 are symmetrically inserted between the two mortise and tenon grooves 5, and the two connecting plates 2 are fixedly connected to an inserting plate 4 on the opposite sides thereof, and the two base boards 1 are provided with a slot 3 which is plugged into the inserting plate 4 inside the opposite sides thereof; the base board 1 includes a bottom plate 11, a first reinforcement layer 12 provided on the top of the bottom plate 11, and a second reinforcement layer 16 covering the outside of the bottom plate 11 and the first reinforcement layer 12. The first reinforcement layer 12 and the second reinforcement layer 16 are provided to reinforce the bottom plate 11, which can increase the strength and stability of the plywood, thereby improving the overall performance of the plywood. When the base plates 1 are spliced ​​and assembled, the base plates 1 are moved so that the plug-in plates 4 on the connecting plates 2 are plugged into the corresponding slots 3, and the connection between the base plates 1 is completed. The two connecting plates 2 are fitted together so that the mortise and tenon 5 cooperate to form a square structure. The mortise and tenon 6 is inserted into the inside of the mortise and tenon 5 for cooperative connection, which can improve the stability of the connection between the connecting plates 2 and the stability of the connection between the base plates 1. The operation is simple and is conducive to improving the structural strength and stability of the plywood.

[0024] An anti-benzene and anti-formaldehyde coating layer 15 is provided on the outside of the bottom plate 11 and the first reinforcement layer 12 and on the inside of the second reinforcement layer 16. Providing the anti-benzene and anti-formaldehyde coating layer 15 on the outside of the base plate 1 can purify formaldehyde well, thereby effectively degrading formaldehyde in the room.

[0025] The first reinforcing layer 12 is configured as a glass fiber mesh. The mesh structure made of glass fiber as a base material has high tensile strength, which can effectively prevent the board from cracking or deforming when subjected to tension, thereby helping to extend the service life of the plywood.

[0026] The second reinforcement layer 16 is made of a mixture of glass fiber and epoxy resin. The second reinforcement layer 16 formed by the uniform mixture of glass fiber and epoxy resin covers the surface of the substrate 1, which can greatly improve the structural strength of the plywood and help improve the load-bearing capacity and compressive performance of the plywood.

[0027] A sound insulation layer 13 is provided inside the anti-benzene and anti-formaldehyde coating layer 15 and on top of the first reinforcement layer 12. The sound insulation layer 13 can make the plywood have the characteristics of sound absorption and noise reduction, thereby improving the use effect of the plywood.

[0028] A flame retardant board layer 14 is provided on the inner side of the anti-benzene and anti-formaldehyde coating layer 15 and on the top of the sound insulation board layer 13. The flame retardant board layer 14 is set as a rock wool board. The flame retardant board layer 14 uses rock wool board as the main material and has good heat insulation and fire prevention characteristics to enhance the fire safety and thermal insulation effect of the plywood.

[0029] Working Principle: When the base plates 1 are assembled, the base plates 1 are moved so that the inserting plates 4 on the connecting plates 2 are plugged into the corresponding slots 3. This completes the connection between the base plates 1. The two connecting plates 2 fit together so that the mortise and tenon 5 cooperate to form a square structure. The mortise and tenon 6 is inserted into the mortise and tenon 5 to form a mating connection. This improves the stability of the connection between the connecting plates 2 and the stability of the connection between the base plates 1. The operation is simple and helps to improve the structural strength and stability of the plywood.

[0030] By providing the first reinforcement layer 12 and the second reinforcement layer 16 to reinforce the bottom plate 11 , the strength and stability of the plywood can be increased, thereby improving the overall performance of the plywood.
