Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wood board material, especially to a crackproof wood board. BACKGROUND

[0002] Wood board is a common building material with various types and wide application fields. Wood board is made of wood or other wood fiber raw materials. According to different production methods and materials, wood board can be divided into various types, including but not limited to solid wood board, which is made of whole natural wood and retains the natural texture and texture of wood, with high strength and durability. Solid wood board is generally classified according to the actual name of the board without uniform standard specifications. Plywood, also known as thin-core board or multi-layer board, is made of three or more layers of one-millimeter-thick veneer or thin board glued and hot-pressed, which is the most commonly used material for handmade furniture. These boards are solid, durable, and natural in texture, making them the best choice for decoration.

[0003] Therefore, Chinese patent number CN220734868U discloses a crackproof multi-layer solid wood board. The multi-layer solid wood board is provided with a paint layer on the surface, including an edge sealing layer. The edge sealing layer is fixed on the side of the multi-layer solid wood board and completely covers the side of the multi-layer solid wood board. The paint layer is located on the side of the edge sealing layer away from the multi-layer solid wood board. This solves the problem of cracking of the paint surface on the side and cross section of the multi-layer solid wood board, which requires an additional paint repair process. The utility model forms a sealing strip on the side and cross section of the multi-layer solid wood board by pre-sealing the multi-layer solid wood board before painting. The sealing strip and the outer periphery of the multi-layer solid wood board are painted as a whole, thereby avoiding cracking of the paint surface on the side and cross section of the multi-layer solid wood board, simplifying the production process, saving manufacturing costs, and improving production efficiency.

[0004] Today's wood board can basically meet people's use requirements, but there are still some problems, as follows:

[0005] 1. The wood board is difficult to prevent cracking. When the external environment humidity changes, it will affect the wood. When the environmental humidity is too high, the wood will swell. When the environmental humidity is too low, the wood will shrink. This repeated swelling and shrinking process will cause stress inside the wood, which will cause cracking, thereby affecting the overall strength of the wood, increasing the risk of wood decay, and shortening the service life of the wood.

[0006] 2. The wood board has poor sound insulation effect. Wood board is often used as wall facing material and for dividing large space, but the sound insulation effect of general wood board is limited. Even in the same floor, the sound between different rooms may interfere with each other, affecting the privacy and comfort of the occupants. UTILITY MODEL CONTENT

[0007] The utility model discloses a kind of anti-cracking wood boards, to solve the defect that the existing wood board is difficult to prevent cracking, difficult to have good sound insulation effect.

[0008] To solve the above technical problems, the utility model provides the following technical scheme: an anti-cracking wood board, comprising a first edge strip;

[0010] The top end of the first wood board is provided with a wear-resistant structure, and one side of the second edge strip is provided with a second wood board.

[0011] The bottom end of the first wood board is bonded with a crack-resistant structure, and the bottom end of the crack-resistant structure is provided with a sound insulation structure.

[0012] In use, first, two reinforcing plates are installed between the first wood board and the second wood board, the first wood board and the second wood board are connected with the reinforcing plates by glass fiber mesh and epoxy resin adhesive layer, deformation and cracking of the first wood board and the second wood board are avoided, wood blocks are used to support between the two reinforcing plates, foam boards and rock wool boards are added in the space formed, sound insulation effect of the wood board is increased, POSS coating, polyurethane paint coating and perchloroethylene anticorrosive paint coating are arranged on the surfaces of the first wood board and the second wood board, the surfaces of the wood board are protected, and the surfaces of the wood board are prevented from being scratched.

[0013] Further, the wear-resistant structure includes POSS coating, polyurethane paint coating and perchloroethylene anticorrosive paint coating, the perchloroethylene anticorrosive paint coating is arranged at the top end of the first wood board, the top end of the perchloroethylene anticorrosive paint coating is provided with the polyurethane paint coating, and the top end of the polyurethane paint coating is provided with the POSS coating. Multiple wear-resistant coatings protect the surface of the wood board and prevent the wood board from being damaged.

[0014] Further, the crack-resistant structure includes tung oil coating, epoxy resin adhesive layer, glass fiber mesh and reinforcing plate, the tung oil coating is arranged at the top end of the first wood board, the epoxy resin adhesive layer is bonded at the bottom end of the first wood board, and the bottom end of the epoxy resin adhesive layer is bonded with the glass fiber mesh. The surfaces of the first wood board and the second wood board are waterproofed to prevent the wood board from being damp and deformed.

[0015] Further, the bottom end of the glass fiber mesh is bonded with the reinforcing plate, and the reinforcing plate is symmetrically distributed about the central axis of the first edge strip. The strength of the reinforcing plate is used to structurally reinforce the first wood board and the second wood board to prevent the wood board from deforming.

[0016] Furthermore, the sound insulation structure includes a foam board, a rock wool board, and wooden strips. The rock wool board is placed on one side of the first edge banding strip to block the transmission of sound and enhance the sound insulation effect of the wooden board.

[0017] Furthermore, the foam board is disposed at the bottom of the reinforcing plate, and the surface of the foam board is provided with sound-absorbing holes. The foam board can slow down the transmission speed of sound waves, and at the same time, the sound-absorbing holes can absorb and disperse sound wave energy, thereby improving sound insulation performance.

[0018] Furthermore, the wooden strips are installed at the bottom of the reinforcing plate, and the wooden strips are arranged at equal intervals at the bottom of the reinforcing plate. The wooden strips separate the two reinforcing plates to form a cavity, which facilitates the installation of rock wool board and foam board and avoids crushing the rock wool board and foam board.

[0019] The present invention provides a crack-resistant wooden board, the advantages of which are as follows: by applying a tung oil coating to the surfaces of the first and second wooden boards, external moisture is prevented from seeping into the first and second wooden boards, thus preventing deformation due to thermal expansion and contraction. A fiberglass mesh and a reinforcing plate are bonded to one end of the first and second wooden boards with an epoxy resin adhesive layer. The fiberglass mesh improves the bending strength, shear strength, and tensile strength of the wooden boards, while the reinforcing plate enhances the overall structural strength, preventing the first and second wooden boards from deforming due to external forces and thus preventing cracking. This maintains the flatness and stability of the wooden boards, thereby achieving the purpose of preventing cracking.

[0020] Multiple wooden strips are evenly installed between two layers of reinforcing boards to form cavities. Foam boards and rock wool boards are then installed inside these cavities. The wooden strips protect the foam boards and rock wool boards from being crushed. The foam boards slow down the transmission speed of sound waves, and the sound-absorbing holes on their surface absorb and disperse sound wave energy, improving sound insulation performance. The rock wool boards also effectively block sound transmission, forming multiple sound insulation layers together with the foam boards to further enhance the sound insulation effect. This achieves the goal of making the wood boards have good sound insulation performance. Attached Figure Description
