Technical Field

[0001] This application relates to the technical field of solid wood particle boards, and particularly to a multi-layer solid wood particle board. Background Art

[0002] Solid wood particle board is a common board in our life. It is mainly made by breaking logs into pieces of wood or wooden poles, using fine wood fibers on both sides, long wood fibers in the middle, and adding adhesives, and then gluing them into an artificial board under the action of heat and pressure. Solid wood particle board also belongs to a kind of particle board. The wood fiber particles in this board are relatively large and are spliced by debris of this kind of wood board. Therefore, the surface is flat and delicate, without insect holes, knots, etc.

[0003] Although solid wood particle board has undergone a certain degree of moisture-proof treatment during the manufacturing process, long-term contact with a humid environment will still cause the board to deform and expand. Therefore, in the daily use of solid wood particle board, attention still needs to be paid to waterproofing, heat protection, and sun protection. Otherwise, the solid wood particle board is prone to deformation under the influence of the environment. Utility Model Content

[0004] In order to improve the problem that solid wood particle board is prone to deformation under the influence of the environment, this application provides a multi-layer solid wood particle board.

[0006] A multi-layer solid wood particle board includes an inner core board body, four corner guards, an upper cushion layer, a lower cushion layer, and a set of edge guards. Each corner guard has a slot formed in the middle. The four corners of the inner core board body are respectively inserted into the slots of the four corner guards, and the corners of the inner core board body are adhesively fixed to the inner walls of the corner guards. The top and bottom of the inner core board body are respectively adhesively bonded with the upper cushion layer and the lower cushion layer, and the upper surface of the upper cushion layer is flush with the upper surfaces of the four corner guards, and the lower surface of the lower cushion layer is flush with the lower surfaces of the four corner guards. The set of edge guards includes four guard plates. Each guard plate is disposed between two adjacent corner guards, and the guard plates are respectively adhesively fixed to the inner core board body, the corner guards, the upper cushion layer, and the lower cushion layer. The outer side walls of the guard plates are flush with the outer sides of the corner guards.

[0007] Furthermore, the upper cushion layer and the lower cushion layer have the same shape, and notches matching the corner guards are formed at the four corners of the upper cushion layer and the lower cushion layer. The upper cushion layer and the lower cushion layer are both set as cork pads, and the upper cushion layer and the lower cushion layer both have a closed cell structure.

[0008] Furthermore, the inner angles of the corner guards are tightly pressed against and fit with the corners of the inner core board body, and the height of the slot is adapted to the thickness of the inner core board body.

[0017] The technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0018] An embodiment of the present application discloses a multi-layer solid wood particle board. Refer to Figures 1 to 3 , the multi-layer solid wood particle board includes an inner core board body 10, four corner guards 20, an upper cushion layer 30, a lower cushion layer 40, and a set of edge guards 50. A slot 21 is formed in the middle of each corner guard 20, and the height of the slot 21 is adapted to the thickness of the inner core board body 10. The four corners of the inner core board body 10 can be respectively inserted into the slots 21 of the four corner guards 20, so that the inner angles of the corner guards 20 are tightly abutted and fitted with the corners of the inner core board body 10. During the assembly process, an adhesive can also be used to bond and fix the corners of the inner core board body 10 to the inner walls of the corner guards 20. The upper and lower surfaces of the inner core board body 10 can be adhesively bonded to the upper cushion layer 30 and the lower cushion layer 40. The upper cushion layer 30 and the lower cushion layer 40 have the same shape, and notches 31 matching the corner guards 20 are formed at the four corners of the upper cushion layer 30 and the lower cushion layer 40, so that after assembly, the upper surface of the upper cushion layer 30 is flush with the upper surfaces of the four corner guards 20; the lower surface of the lower cushion layer 40 is flush with the lower surfaces of the four corner guards 20. A set of edge guards 50 includes four guard plates, each guard plate is disposed between two adjacent corner guards 20, and the width of each guard plate in the set of edge guards 50 is equal to the height of the corner guard 20, and the length of each guard plate is adapted to the distance between two adjacent corner guards 20, so that the guard plates can be respectively bonded and fixed to the inner core board body 10, the corner guards 20, the upper cushion layer 30, and the lower cushion layer 40, and the outer side walls of the guard plates are flush with the outer sides of the corner guards 20 to protect the outer sides of the inner core board body 10, the corner guards 20, the upper cushion layer 30, and the lower cushion layer 40.

[0019] In this embodiment, both the upper cushion layer 30 and the lower cushion layer 40 can be cut from a cork mat to the required size and shape. The cork mat has a closed cell structure, so that the cork mat has good moisture-proof and water-resistant properties, and good shock-proof and buffering properties. In addition, the cork mat is heat-insulating, making its heat preservation, cold protection, and low-temperature performance excellent, and it can withstand severe cold and exposure to the sun.

[0020] In this embodiment, the inner core board body 10 can include an upper layer particle board 11, a lower layer particle board 12, and a splicing board 13. The upper layer particle board 11 and the lower layer particle board 12 are respectively located above and below the splicing board 13, and both the upper layer particle board 11 and the lower layer particle board 12 are bonded and fixed to the splicing board 13. The splicing board 13 can be composed of multiple solid wood strips. The opposite sides of every two adjacent solid wood strips are in contact and bonded and fixed. The outer edges of the multiple solid wood strips are polished to form straight edges, so that the multiple solid wood strips form a complete splicing board 13.

[0021] In this embodiment, the guard plates in a set of edge guards 50 can be made of wood-plastic composite boards, polyvinyl chloride (PVC) boards, or aluminum-plastic boards (composed of aluminum plates and polyethylene plastic films) and other boards with good moisture-proof capabilities. For example, wood-plastic composites can use polyethylene, polypropylene, polyvinyl chloride, etc. to replace the usual resin adhesives and be mixed with more than 50% of waste plant fibers such as wood powder, rice husks, and straws to form new wood materials, and then made into boards through plastic processing techniques such as extrusion, molding, and injection molding. Wood-plastic composite boards can resist strong acids and alkalis, are water-resistant, corrosion-resistant, and are not easy to breed bacteria or be eaten by insects. Wood-plastic composites contain plastics, so they have good elastic moduli. In addition, due to containing fibers and being fully mixed with plastics, they have physical and mechanical properties such as compressive resistance and bending resistance equivalent to those of hardwoods, and their durability is significantly better than that of ordinary wood materials. The surface hardness is high, generally 2 to 5 times that of wood. By adding additives, plastics can undergo polymerization, foaming, curing, modification, etc. to change, thereby changing the density, strength, and other properties of wood-plastic materials, and can also meet special requirements such as anti-aging, anti-static, and flame retardancy.

[0022] It can be understood that, for example, waterproof and fireproof boards made of fiber cement as the base material and incorporated with high-quality mineral ceramsite, glass fiber, etc., or moisture-proof boards such as fiberglass boards and granite boards can also be used as guard plate materials, which will not be elaborated here.

[0023] Through the laying of the upper cushion layer 30, the lower cushion layer 40, and a set of edge guards 50 on the outer side of the inner core plate body 10, this multi-layer solid wood particle board has good moisture-proof and water-resistant properties during use, and can also have a certain effect of resisting corrosion by chemicals such as seawater, grease, acids, and alkalis, thereby increasing the service life of the multi-layer solid wood particle board during laying and use;

[0024] In addition, through the setting of the upper cushion layer 30 and the lower cushion layer 40, the solid wood particle board can also have good shock absorption and buffering properties during laying and use, so that when the solid wood particle board is used as a floor, it can effectively reduce the damage or noise of the floor caused by heavy objects falling in daily life.

[0025] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
