Description

Technical Field

[0001] This utility model relates to the field of plywood processing technology, specifically to a biodegradable plywood. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It typically uses an odd number of veneer layers, with the grain direction of adjacent veneers perpendicular to each other. This structural design makes plywood stronger and more stable than ordinary wood, while reducing wood deformation and cracking. Based on its structure, plywood can be classified into plywood, sandwich plywood, and composite plywood. Sandwich plywood consists of two layers of thin veneers with a layer of wood or metal sandwiched in between; composite plywood consists of two or more different materials, such as metal, plastic, and ceramic, bonded together with adhesives.

[0003] Plywood, a type of wood material, is a flammable material. The flammability of plywood is a major cause of fires. Existing plywood is difficult to flame-retard, thus reducing safety and practicality. Utility Model Content

[0004] The purpose of this invention is to provide a biodegradable plywood to address the issues raised in the background art, which state that plywood, being a wood-based material, is flammable and a major cause of fires. Furthermore, existing plywood is difficult to control the spread of fire, thus reducing safety and practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a biodegradable plywood, comprising a surface anti-slip layer, a surface substrate layer disposed below the surface anti-slip layer, a high-strength reinforcing layer fixed at the lower end of the surface substrate layer, a bottom substrate layer disposed below the high-strength reinforcing layer, a heat-insulating and fireproof layer disposed between the bottom substrate layer and the high-strength reinforcing layer, a supporting frame layer disposed between the high-strength reinforcing layer and the heat-insulating and fireproof layer, and an auxiliary reinforcing mechanism disposed on the side surfaces of the surface anti-slip layer and the bottom substrate layer. This mechanism is installed by embedding limiting blocks on the surface of metal reinforcing members into the surface substrate layer and the bottom substrate layer. Simultaneously, rubber anti-slip strips on the surface of the limiting blocks increase friction, and friction protrusions on the surface of the metal reinforcing members press against the sides of the plywood, improving overall stability.

[0006] Preferably, two fastening grooves are provided on both sides of the surface of the top substrate layer and the bottom substrate layer.

[0007] By adopting the above technical solution, the thickness can ensure that the surface anti-slip layer has sufficient structural strength to support the protective protrusion, and will not increase the overall weight of the plywood or affect the adhesion of each layer due to excessive thickness. This achieves a balance between anti-slip function and lightweight. Natural rubber latex has excellent elasticity and coefficient of friction, which can significantly improve the surface anti-slip performance and adapt to various environments such as dry and humid.

[0008] Preferably, the supporting frame layer has a grid-like design, and the interior of the heat insulation and fireproof layer has a porous structure.

[0009] By adopting the above technical solution, bamboo fiber has high strength and good toughness, while straw fiber is widely available and low in cost. The combination of the two can take into account both the mechanical properties and economy of the substrate. Both are natural plant fibers that can be completely degraded, thus achieving the environmental protection characteristics of plywood from the substrate level and solving the resource waste and pollution problems of traditional wood plywood.

[0010] Preferably, the surface of the anti-slip layer is provided with protective protrusions, and the surface anti-slip layer and the protective protrusions are made of the same material.

[0011] Using the above technical solution, fiberglass cloth has the characteristics of high strength and high modulus, which can effectively improve the tensile and impact resistance of plywood, enhance the overall structural stability, and avoid deformation or breakage due to stress during use. The ultra-thin thickness significantly enhances the strength without significantly increasing the weight or thickness of the plywood. In addition, fiberglass cloth has good compatibility with other layer materials, can be tightly bonded, and does not affect the synergistic effect of each layer.

[0012] Preferably, the protective protrusions have an arc-shaped surface and are regularly arranged on the surface of the anti-slip layer.

[0013] Using the above technical solution, the porous structure of expanded vermiculite can effectively block heat transfer and improve heat insulation performance. Magnesium hydroxide is an environmentally friendly flame retardant that decomposes into water and magnesium oxide at high temperatures, which can inhibit the spread of fire and reduce smoke release, thus achieving fire protection and solving the safety hazards of flammability of traditional plywood.

[0014] Preferably, the auxiliary reinforcement mechanism includes a metal reinforcement member disposed on the side surface of the surface substrate layer and the bottom substrate layer. A limiting block is fixedly connected to the surface of the metal reinforcement member, a rubber anti-slip strip is fixedly connected to the surface of the limiting block, and a friction protrusion is fixedly connected to the surface of the metal reinforcement member.

[0015] By adopting the above technical solution, the overall strength and protective performance are increased through metal reinforcement, ensuring the overall bending resistance and improving the stability of the overall anti-slip effect.

[0016] Preferably, the limiting insert and the fastening slot form a snap-fit ​​connection, the rubber anti-slip strip is inclined, the friction protrusion is strip-shaped, and the vertical cross-section of the friction protrusion is triangular.

[0017] By adopting the above technical solution, the connection between the limiting insert and the fastening slot is increased by the rubber anti-slip strip, which increases the stability after connection. The friction protrusions press against the side of the plywood, increasing the friction and improving the overall compactness.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the biodegradable plywood:

[0019] 1. The surface and bottom substrate layers are made of natural plant fibers such as bamboo fiber and straw fiber, which are completely biodegradable, reducing the resource waste and environmental pollution caused by traditional wood plywood from the source. The surface anti-slip layer and protective protrusions are designed with the same material in a regular arc shape to enhance the anti-slip effect and adapt to various environments. The heat insulation and fireproof layer is made of expanded vermiculite and magnesium hydroxide, which uses a porous structure to block heat and achieve flame retardancy, effectively solving the safety hazards of flammability of traditional plywood, and taking into account both environmental protection and practical functions.

[0020] 2. The high-strength reinforcement layer uses fiberglass cloth, which enhances tensile and impact resistance due to its high strength and high modulus. The addition of the support frame layer further strengthens the structural support and disperses external loads. In the auxiliary reinforcement mechanism, the limiting blocks of the metal reinforcement members are connected with the fastening slotted interlocking, and the inclined rubber anti-slip strips increase friction. The strip-shaped triangular friction protrusions press the sides, improving the overall stability in multiple dimensions and effectively preventing deformation or interlayer separation caused by stress during use, thus extending the service life.

[0021] 3. The protective protrusions on the surface anti-slip layer are arranged in a regular arc shape, which increases friction to prevent slippage and avoids scratches caused by sharp edges, thus improving safety. The auxiliary reinforcement mechanism not only enhances structural stability but also reinforces the sides with metal fasteners, reducing the risk of collision damage. The overall design ensures performance without excessively increasing weight and thickness, making it widely applicable to scenarios with requirements for environmental protection, strength, anti-slip properties, and fire resistance.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a biodegradable plywood, comprising a surface anti-slip layer 1, a surface substrate layer 2, a high-strength reinforcing layer 3, a heat-insulating and fire-resistant layer 4, a bottom substrate layer 5, protective protrusions 6, metal reinforcements 7, limiting blocks 8, rubber anti-slip strips 9, fastening grooves 10, friction protrusions 11, and a support frame layer 12. The surface anti-slip layer 1 has a surface substrate layer 2 below it, a high-strength reinforcing layer 3 fixed to its lower end, and a bottom substrate layer 5 below it. Both sides of the surface substrate layer 2 and the bottom substrate layer 5 have two fastening grooves 10. The support frame layer 12 has a grid-like design. The heat-insulating and fire-resistant layer 4 has a porous structure. The surface anti-slip layer 1 provides basic anti-slip capability through the properties of natural rubber latex, and the regularly arranged arc-shaped protective protrusions 6 on its surface further increase the friction with contacting objects. This dual action effectively prevents objects from slipping or people from slipping, improving safety during use.

[0031] A heat-insulating and fireproof layer 4 is provided between the bottom substrate layer 5 and the high-strength reinforcing layer 3. A supporting frame layer 12 is provided between the high-strength reinforcing layer 3 and the heat-insulating and fireproof layer 4. The surface of the surface anti-slip layer 1 is provided with protective protrusions 6, and the surface anti-slip layer 1 and the protective protrusions 6 are made of the same material. The surface of the protective protrusions 6 is arc-shaped and is regularly arranged on the surface of the surface anti-slip layer 1. The surface substrate layer 2 and the bottom substrate layer 5 serve as the main supporting structure, relying on the characteristics of bamboo fiber and straw fiber to provide stable load-bearing capacity. The glass fiber cloth of the high-strength reinforcing layer 3 enhances the overall tensile and impact resistance. The supporting frame layer 12 is located between the high-strength reinforcing layer 3 and the heat-insulating and fireproof layer 4, further dispersing the load and improving the plywood's bending and compression resistance, thus jointly ensuring the structural strength.

[0032] The auxiliary reinforcement mechanism includes a metal reinforcement member 7, which is disposed on the side surface of the surface substrate layer 2 and the bottom substrate layer 5. A limiting block 8 is fixedly connected to the surface of the metal reinforcement member 7, and a rubber anti-slip strip 9 is fixedly connected to the surface of the limiting block 8. A friction protrusion 11 is fixedly connected to the surface of the metal reinforcement member 7. The heat insulation and fireproof layer 4 uses the porous structure of expanded vermiculite to block heat transfer and achieve heat insulation function. In addition, magnesium hydroxide decomposes into water and magnesium oxide at high temperature, which plays a flame retardant role, inhibits the spread of fire and reduces the release of smoke, effectively improving the fire safety of the device.

[0033] The surface anti-slip layer 1 and the bottom substrate layer 5 are provided with auxiliary reinforcement mechanisms. These mechanisms are embedded in the surface substrate layer 2 and the bottom substrate layer 5 through limiting blocks 8 on the surface of the metal reinforcement member 7. At the same time, the rubber anti-slip strips 9 on the surface of the limiting blocks 8 increase the friction, and the friction protrusions 11 on the surface of the metal reinforcement member 7 press against the side of the plywood to improve overall stability. The limiting blocks 8 and the fastening slots 10 form a snap-fit ​​connection. The rubber anti-slip strips 9 are inclined, and the friction protrusions 11 are strip-shaped with a triangular cross-section in the vertical direction. The metal reinforcement member 7 of the auxiliary reinforcement mechanism is snap-fitted to the surface substrate layer 2 and the bottom substrate layer 5 through the limiting blocks 8. The inclined rubber anti-slip strips 9 on the surface of the limiting blocks 8 increase the connection friction and prevent loosening. The triangular strip-shaped friction protrusions 11 on the surface of the metal reinforcement member 7 press against the side of the plywood to further enhance the tightness of the bond between the layers and improve the overall structural stability.

[0034] In the production of this biodegradable plywood, metal reinforcement 7 is processed, a limiting block 8 is fixed on its surface, and an inclined rubber anti-slip strip 9 is installed on the surface of the limiting block 8. At the same time, a strip-shaped triangular friction protrusion 11 is fixed on the surface of the metal reinforcement 7.

[0035] Bamboo fiber and straw fiber are crushed, screened, mixed, and filled into molds respectively. They are pressed under appropriate temperature and pressure to form a board of specified thickness. After cooling, two fastening grooves 10 are opened on both sides of the surface of the top substrate layer 2 and the bottom substrate layer 5.

[0036] Apply natural adhesive to the lower surface of the surface substrate layer 2, lay the fiberglass cloth flat and press it firmly to fix the high-strength reinforcement layer 3 to the surface substrate layer 2.

[0037] A support frame layer 12 is laid under the high-strength reinforcement layer 3, and then a mixture of expanded vermiculite and magnesium hydroxide is laid under the support frame layer 12 to form a heat insulation and fireproof layer 4, ensuring that each layer is tightly bonded.

[0038] Apply adhesive under the heat insulation and fireproof layer 4, cover and compact the bottom substrate layer 5, so that the bottom substrate layer 5 is firmly bonded to the heat insulation and fireproof layer 4 to form the main structure of plywood.

[0039] The prepared surface anti-slip layer material is uniformly coated on the surface substrate layer 2, and regular arc-shaped protective protrusions 6 are pressed on the surface using a specific mold;

[0040] Align the limiting insert 8 on the surface of the metal reinforcement 7 with the fastening slots 10 of the surface substrate layer 2 and the bottom substrate layer 5 for embedding and installation. Use the rubber anti-slip strip 9 on the surface of the limiting insert 8 to increase friction, and at the same time make the friction protrusion 11 on the surface of the metal reinforcement 7 press against the side of the plywood to improve overall stability.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
