[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0054] Embodiment 1:

[0055] Please refer to Figure 1 , a processing method of an environment-friendly composite multi-layer board, comprising the following steps:

[0056] S1. Select suitable wooden boards to make the required outer panel 1, spacer 2 and lower bottom panel 3 respectively and perform pretreatment on them;

[0057] S2. Process the pretreated wooden boards, make tenons on one end face of the outer panel 1 and the lower bottom panel 3 respectively, and make mortises on both end faces of the spacer 2;

[0058] S3. Use a punching device to open a plurality of evenly spaced reserved holes in the middle of the outer panel 1 and the spacer 2;

[0059] S4. Through mechanical connection of tenons and mortises, laminate and fix the outer panel 1, spacer 2 and lower bottom panel 3 into one body;

[0060] S5. Put the laminated and fixed wooden board into a hot press and perform hot pressing treatment under high temperature and high pressure conditions to make the connection between the wood layers closer;

[0061] S6. Use screw mechanical fasteners to firmly connect the laminated wooden boards so that the outer panel 1, spacer 2 and lower bottom panel 3 are formed into a complete composite multi-layer board;

[0062] S7. Inject waterproof gel into a plurality of reserved holes respectively, and then press the environment-friendly blocks 4 into the reserved holes respectively for solidification.

[0063] Through the precise connection of tenons and mortises and hot pressing treatment, the close connection between the wooden board layers is enhanced, and the stability and strength of the overall structure are improved. The use of screw mechanical fasteners further ensures the firm forming of the outer panel 1, the partition board 2 and the lower base board 3, thereby increasing the durability of the board. The injected waterproof gel and environmentally friendly blocks not only enhance the waterproof performance of the board, but also have the function of absorbing harmful substances and releasing beneficial substances, thereby improving the indoor air quality and having environmental protection and health protection effects.

[0064] The preprocessing in step S1 specifically includes the following steps:

[0065] S101, sawing the logs into specified lengths according to the size and thickness of the composite board;

[0066] S102, making continuous thin wood slices by rotating the log and cutting its surface horizontally;

[0067] S103, putting the cut wood into the dryer and adjusting the temperature and humidity to appropriate levels, usually 60°C-80°C;

[0068] S104. After drying, the wood boards need to be inspected in detail to exclude those with cracks, deformation, decay or other defects;

[0069] S105. Polish the surface of the inspected wood and clean the dust.

[0070] By sawing the logs into specified lengths according to the size and thickness of the composite board, the dimensional accuracy and standardization of the wood in subsequent processing are ensured; by rotating the logs and cutting them horizontally, continuous thin wood slices are made, which improves material utilization and reduces waste; the cut wood boards are placed in the dryer and adjusted to the appropriate temperature and humidity, usually 60℃-80℃, to ensure that the wood is evenly dried, reduce internal stress, and prevent cracking and deformation during the drying process; the dried wood boards are carefully inspected to exclude boards with cracks, deformation, rot or other defects, ensuring that each piece of wood meets high quality standards; the surface of the wood that passes the inspection is polished and dust-cleaned to ensure that the wood surface is smooth and free of impurities, providing a good foundation for subsequent mechanical connection and lamination processes; In summary, the pretreatment method not only improves the accuracy and utilization of wood processing, but also ensures the quality of the wood through uniform drying and strict inspection, optimizes the surface treatment, lays a solid foundation for subsequent steps, and improves the overall performance and quality of the final composite multilayer board.

[0071] The manufacturing of the tenon and the mortise in step S2 specifically includes the following steps:

[0072] S201, marking the positions of the tenon and the mortise at the joints of the two wooden boards near one end;

[0073] S202, use CNC machinery to fix the tenons around the wooden board at the upper and lower wooden board marks;

[0074] S203, using a punching device to carve out matching mortises at the marks corresponding to the tenons on the middle wooden board;

[0075] S204. Grind and fine-tune the processed tenons and mortises to ensure a tight fit between the tenons and mortises.

[0076] Marking the positions of the tenons and mortises at the joints where the wooden boards are close to each other ensures the accuracy of the production position and provides an accurate reference for subsequent processing; using CNC machinery to fix the tenons around the wooden boards at the marks on the upper and lower wooden boards improves processing efficiency and accuracy and reduces human errors; using punching equipment to carve out matching mortises at the marks corresponding to the middle wooden board and the tenon ensures that the sizes and positions of the tenons and mortises are accurate and consistent, ensuring a tight connection; polishing and fine-tuning the processed tenons and mortises ensures a close fit between them and further improves the firmness and stability of the connection; in summary, the method of making tenons and mortises not only improves efficiency and accuracy through precise positioning and efficient processing, but also ensures a close fit between the tenons and mortises through precise matching and fine adjustment, enhances the overall strength and stability of the composite multilayer board, and ensures the quality and performance of the final product.

[0077] The hot pressing treatment in step S4 specifically includes the following steps:

[0078] S401, placing the laminated and fixed wood board into a hot press, setting appropriate temperature and pressure, the temperature range is 120℃-150℃, and the pressure range is 1-2MPa;

[0079] S402, maintaining the hot pressing time at 20-30 minutes to ensure that the connection between the wood layers is fully cured;

[0080] S403. After the hot pressing treatment is completed, the wood board is slowly cooled to room temperature to prevent deformation or cracking caused by excessive internal stress in the wood.

[0081] Place the laminated and fixed wooden boards into a hot press, set appropriate temperature and pressure to ensure that the connection between the wood layers is tighter and firmer under high temperature and high pressure conditions, thereby improving the overall strength and stability of the composite board; maintain a hot pressing treatment time of 20-30 minutes to ensure that the connection between the wood layers is fully cured and enhance the durability and reliability of the board; after the hot pressing treatment is completed, slowly cool the wooden board to room temperature to prevent deformation or cracking due to excessive internal stress, and ensure the shape stability and structural integrity of the board; in summary, the hot pressing treatment method in step S4 effectively improves the strength, durability and stability of the composite multilayer board through appropriate temperature and pressure settings, sufficient hot pressing time, and a slow cooling process, thereby ensuring the quality and performance of the final product.

[0082] See also Figure 2-5 The environmental protection block 4 in step S7 includes a mounting block 41, which is fixedly connected to the reserved hole. An annular reserved groove 42 is provided at the upper end of the mounting block 41, and a filling cavity 43 is provided inside the mounting block 41. A pair of connecting micropores 44 are provided between the filling cavity 43 and the annular reserved groove 42. The filling cavity 43 is filled with environmental protection particles 45. The gas enters the annular reserved groove 42 and penetrates into the filling cavity 43 through the connecting micropores 44 and is absorbed by the environmental protection particles 45, thereby purifying the air and improving the environmental protection effect.

[0083] The environmentally friendly particles 45 are a combination of one or more of activated carbon, zeolite, photocatalyst, negative ion material, diatomaceous earth, bamboo charcoal, and mineral crystals, wherein activated carbon has a highly developed pore structure and a huge specific surface area, and can effectively absorb harmful gases in the air such as formaldehyde, benzene, ammonia, etc., and some improved activated carbon materials can release negative ions, which help to purify the air and improve indoor air quality; zeolite is a natural mineral with a unique crystal structure, which can absorb harmful gases such as ammonia and formaldehyde, and zeolite can release trace elements such as potassium, calcium, and magnesium that are beneficial to the human body through ion exchange; photocatalysts can produce free radicals with strong oxidizing ability under the irradiation of ultraviolet rays or visible light, decompose harmful substances such as formaldehyde, benzene, volatile organic compounds, etc. in the air, and at the same time Time catalyst can also effectively kill bacteria and viruses and purify the air; negative ion materials release negative ions through physical or chemical methods, negative ions can neutralize positive ions in the air and improve air quality, and negative ion materials are often used in combination with adsorption materials, which can effectively adsorb harmful substances in the air; diatomaceous earth has a porous structure and can adsorb harmful gases such as formaldehyde and benzene in the air, and improved diatomaceous earth materials can release negative oxygen ions and purify the air; bamboo charcoal has a developed pore structure and can adsorb harmful gases such as formaldehyde and benzene in the air, and bamboo charcoal can release negative ions and far infrared rays to improve air quality and human health; mineral crystals such as tourmaline, tourmaline mineral crystals can release negative ions and far infrared rays to enhance the air purification effect, and these mineral crystals also have a certain ability to adsorb harmful substances.

[0084] However, the combination of the above materials has better effect, among which activated carbon and photocatalyst, activated carbon has strong adsorption capacity and can first adsorb most of the harmful gases in the air, and the photocatalyst decomposes the residual harmful substances under the irradiation of ultraviolet light or visible light. The adsorption of activated carbon has a saturation limit. The decomposition effect of the photocatalyst can extend the service life of the activated carbon; zeolite and negative ion material, zeolite can adsorb harmful substances in the air, and the negative ion material can release negative ions to improve the air quality. This combination can not only purify the air, but also improve the air freshness and comfort by releasing negative ions; diatomaceous earth and bamboo charcoal, diatomaceous earth and bamboo charcoal both have porous structures and can effectively adsorb harmful gases. The combined use can enhance the overall adsorption capacity, and bamboo charcoal can release negative ions and far infrared rays to further improve the air quality; tourmaline mineral crystals and photocatalysts, tourmaline mineral crystals can release negative ions and far infrared rays, and photocatalysts can decompose harmful substances. The combined use can provide all-round air purification and health protection. The mineral crystals provide continuous negative ion release, and the photocatalyst continuously decomposes harmful substances under light conditions to form a long-lasting purification effect.

[0085] A disassembly cover 46 is provided in the middle of the upper end of the mounting block 41, and a decorative pattern is provided on the surface of the disassembly cover 46. The disassembly cover 46 can play a decorative role to improve the aesthetics of the composite multilayer board, and the disassembly cover 46 can also be inlaid with decorations on its surface or replaced by transparent silicone.

[0086] The disassembly cover 46 is connected to the mounting block 41 by threads, and the disassembly cover 46 is located at the upper end of the filling cavity 43. Through the threaded connection, it can be easily removed to replace and fill the environmentally friendly particles 45.

[0087] The connecting micropore 44 is opened near the opening of the annular reserved groove 42. By setting the position, it can prevent excessive water in the annular reserved groove 42 from seeping into the connecting micropore 44 to a certain extent. The connecting micropore 44 has a smaller aperture and is opened near the opening of the annular reserved groove 42. Under the action of water tension, it can reduce the infiltration of water into the filler cavity 43. At the same time, when the annular reserved groove 42 is full of water, it can not only prevent dust from passing through the connecting micropore 44 into the filler cavity 43, but also the water surface will float the dust and make the dust located on the upper surface of the composite multilayer board, thereby facilitating cleaning.

[0088] The production of the environmental protection block 4 in step S7 includes the following specific steps:

[0089] S701, select a wooden block of the same material as the composite multilayer board to make a mounting block 41;

[0090] S702, a groove of a certain depth is cut on the upper end of the mounting block 41 to form an annular reserved groove 42;

[0091] S703, first cut off the middle part of the upper end of the mounting block 41 along the inner wall of the annular reserved groove 42 and chisel out a filler cavity 43;

[0092] S704, grinding the outer side of the upper end of the chiseled filling cavity 43 into a threaded shape, and making a disassembly cover 46 matching the threaded shape;

[0093] S705, a pair of communicating micro holes 44 are drilled along the inner wall of the filler cavity 43 near the disassembly cover 46 to communicate with the annular reserved groove 42;

[0094] S706, unscrew the disassembly cover 46 with a tool, fill the environmentally friendly particles 45 into the filling cavity 43 and then close the cover.

[0095] See also Figure 6, Compressive strength: refers to the resistance of the board when subjected to vertical pressure. After tenon and mortise connection and screw fixation, especially after high temperature and high pressure hot pressing treatment, the compressive strength of the composite multilayer board is significantly improved; Bending strength: refers to the resistance of the board when subjected to bending force. The bending strength of the composite multilayer board after the above treatment is also improved; Environmental protection (formaldehyde purification ability): Ordinary multilayer boards without adding environmentally friendly particles do not have formaldehyde purification ability, but after adding different combinations of environmentally friendly particles (such as activated carbon, photocatalyst, zeolite, etc.), the composite multilayer board shows significant formaldehyde purification ability. Based on its strong adsorption capacity, activated carbon combines the decomposition effect of photocatalyst and the ion exchange effect of zeolite, and the purification rate is gradually improved.

[0096] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0097] This solution enhances the structural stability and durability of the board through the mechanical connection of tenons and mortises, coupled with hot pressing treatment under high temperature and high pressure; the screw mechanical fasteners further firmly connect the layers of wood boards, improving the overall durability; the environmental protection block absorbs the infiltrated gas through the environmental protection particles in the filler cavity to achieve air purification, improve the environmental protection performance of the board, and injects waterproof gel to enhance the waterproof effect; the detachable cover design is convenient for users to replace and fill the environmental protection particles, and the decorative patterns and inlaid decorations on its surface improve the aesthetics; the location design of the connecting micropores effectively prevents dust and excessive moisture from entering the filler cavity, keeping the interior clean and easy to maintain; when the annular reserved groove is full of water, the water surface will float the dust and keep it on the surface of the board for easy cleaning, which not only improves the structural stability, durability and environmental protection performance of the composite multilayer board, but also takes into account aesthetics and ease of maintenance.
