Technical Field

[0001] This utility model relates to the field of board technology, specifically to a multi-layer solid wood environmentally friendly particleboard. Background Technology

[0002] Solid wood particleboard is a type of engineered wood product made by crushing and drying wood or other lignocellulosic materials, adding adhesives, and then hot-pressing them under high temperature and pressure. It is an upgraded version of particleboard and is also known as homogeneous particleboard. Solid wood particleboard has high nail-holding power, good bending and compression resistance, good impact resistance, moisture resistance, mildew resistance, deformation resistance, and relatively good environmental performance (low formaldehyde adhesives can reach E1 / E0 grade).

[0003] Some existing solid wood environmentally friendly particleboards use low-formaldehyde adhesives for bonding, making them more environmentally friendly and thus widely used in the furniture manufacturing industry. However, their structural strength and rigidity are still not good. When used as a load-bearing structure, their load-bearing capacity is lower than that of other more expensive boards such as solid wood boards. Therefore, in order to address the above problems, a multi-layer solid wood environmentally friendly particleboard is proposed. Utility Model Content

Particleboard assemblies 2 are glued to both the upper and lower sides of the heat insulation board 1. Each particleboard assembly 2 includes a metal support plate 21. A protruding support column 22 is fixedly connected to the side of the metal support plate 21 away from the heat insulation board 1. A limiting groove 23 is formed on the metal support plate 21. A particleboard body 24 is glued to the side of the metal support plate 21 away from the heat insulation board 1. A matching groove 25 is formed on the side of the particleboard body 24 close to the heat insulation board 1. A matching protrusion 26 is fixedly connected to the side of the particleboard body 24 close to the heat insulation board 1.

[0017] The protruding support columns 22 and the limiting grooves 23 are evenly and staggeredly distributed on the metal support plate 21, and the mating grooves 25 and the mating protrusions 26 are evenly and staggeredly distributed on the particleboard body 24. All limiting grooves 23 are through grooves. The metal structure composed of the metal support plate 21, the protruding support columns 22, and the limiting grooves 23 can be used to shape the wooden board structure during production of the particleboard body 24, the mating grooves 25, and the mating protrusions 26.

A decorative coating layer 5 is fixedly connected to the back side of each of the two flame retardant layers 4. A transparent wear-resistant layer 6 is fixedly connected to the back side of each of the two decorative coating layers 5. The decorative coating layer 5 can improve the aesthetics of the multi-layer wood board, and the transparent wear-resistant layer 6 can improve the wear resistance of the multi-layer wood board.

[0018] Workflow: The heat insulation board 1 and the particleboard assembly 2 of this device can be bonded together with adhesive. The particleboard assembly 2 and the waterproof layer 3, the waterproof layer 3 and the flame-retardant layer 4, the flame-retardant layer 4 and the decorative coating layer 5, and the decorative coating layer 5 and the transparent wear-resistant layer 6 can all be fixedly connected using existing technologies, including but not limited to adhesive bonding and riveting.

The particleboard body 24, the mating groove 25, and the mating protrusion 26 can be bonded using low-formaldehyde adhesives. A certain proportion of fragrance (including but not limited to tea-flavored and apple-flavored fragrances) can be added to the adhesive to enhance the product's appearance. After production, the material has its own aroma. During the hot pressing stage of the production process, the metal structure consisting of the metal support plate 21, the protruding pillar 22, and the limiting groove 23 is placed under the raw material of the particleboard to be hot-pressed. This allows for the hot pressing production of the wood board structure composed of the particleboard body 24, the matching groove 25, and the matching protrusion 26. Then, a special adhesive is used to glue the metal structure of the metal support plate 21, the protruding pillar 22, and the limiting groove 23 to the wood board structure composed of the particleboard body 24, the matching groove 25, and the matching protrusion 26. The thickness of the metal support plate 21 can be designed according to the needs of use to meet the requirements of different products. This device can improve the structural strength and rigidity of multi-layer wood boards through the metal structure composed of the metal support plate 21, the protruding pillar 22, and the limiting groove 23. Moreover, the structural strength and rigidity obtained through the metal structure support are much higher than those of wood boards and other boards, which can meet the requirements of different furniture for their load-bearing structures. Therefore, this product has a wider range of applications.
