Description

Technical Field

[0001] The present invention relates to a furniture production technology, and more specifically, to a furniture production method based on new environmentally friendly materials. Background Art

[0002] With the continuous improvement of global environmental awareness, the concept of green and sustainable development has gradually become the mainstream of all walks of life, especially in the furniture manufacturing industry. In the production process of traditional furniture, a large amount of non-renewable resources such as natural wood and petrochemical-based plastics are often used, which not only leads to the over-exploitation of forest resources, but also causes serious pollution to the environment. At the same time, the paints and glues used in the production process of many furniture contain a large amount of volatile organic compounds, which pose a potential threat to air quality and human health. Therefore, how to reduce the negative impact on the environment while ensuring the quality and beauty of furniture has become an important issue that needs to be solved in the furniture manufacturing industry. Summary of the invention

[0003] In view of the shortcomings of the prior art, the object of the present invention is to provide a furniture production method based on new environmentally friendly materials.

[0004] To achieve the above object, the present invention provides the following technical solution: a method for producing furniture based on new environmentally friendly materials, comprising the following steps:

[0005] S1. Raw material selection and preparation: Select environmentally friendly materials, including recycled wood, recycled fiberboard, natural plant fiber, and degradable plastic. The mixing ratio is 40%-50% recycled wood, 20%-30% recycled fiberboard, 15%-20% natural plant fiber, and 5%-10% degradable plastic. Among them, recycled wood should be decontaminated and ground into granules, and natural plant fiber and degradable plastic should be dried and surface treated to ensure the stability of their respective physical properties.

[0006] S2. Preparation of environmentally friendly composite materials: The above raw materials are loosened and uniformly mixed mechanically according to a set ratio to obtain a mixed raw material, and then the mixed raw material is compounded at high temperature and high pressure to form an environmentally friendly composite material. The pressing temperature of the composite material is 120°C-150°C, the pressing pressure is 5MPa-7MPa, and the pressing time is 10min-15min. During the pressing process, the moisture content of the composite material is controlled to be less than 5%;

[0007] S3. Drying treatment: Dry the composite material through hot air drying equipment at a drying temperature of 50°C-100°C for 30min-60min. After drying, the moisture content of the composite material is ≤2% to ensure the physical properties of the final product;

[0008] S4. Design and Cutting of Furniture Components: According to the furniture design drawings, use a CNC cutting machine to precisely cut the composite material to obtain the required furniture components, with the cutting size error controlled within ±0.5 mm.

[0009] S5. Surface Treatment and Coating: Conduct surface treatment on the cut furniture components, including but not limited to deburring and cleaning; then, apply an environmentally friendly coating. The environmentally friendly coating consists of the following components: 30%-40% resin, 10%-15% inorganic filler, 20%-30% natural plant fiber, and 10%-20% natural rubber. Among them, the mass ratio of natural plant fiber to natural rubber is 60:40. After coating, use the heat curing method to cure the coating layer. The curing temperature is 100°C - 120°C, the curing time is 30 min - 45 min, and the thickness of the coating layer is 0.5 mm - 1.8 mm.

[0010] S6. Surface Finishing: After curing, polish the surface of the furniture components. The rotation speed of the polishing equipment is 800 rpm - 1200 rpm, and the polishing time is 10 min - 15 min to ensure the surface is smooth. Then, conduct a non-toxic and environmentally friendly dyeing treatment on the surface. The usage amount of the dye is 5%-10% of the total mass of the composite material. The surface of the dyed furniture has a uniform color and no obvious odor.

[0011] S7. Reinforcement and Structural Connection: Use an environmentally friendly glue to reinforce and connect the furniture components. The glue options include water-based glue or bio-based glue. The usage amount of the glue is 2%-5% of the total mass of the components. The curing time of the glue is 2 h - 4 h to ensure that the glue is completely dry and cured without glue overflow. In addition, the connection methods of each furniture component are selected according to the design requirements, including but not limited to mortise and tenon connection, screw connection, and snap connection. The reinforcement parts need to be ensured to be stable and without looseness.

[0012] S8. Finished Product Inspection: Conduct multiple inspections on the furniture that has been connected to ensure compliance.

[0013] S9. Finished Product Packaging: Pack the furniture that has passed the inspection with environmentally friendly materials. The packaging materials include recyclable cardboard boxes or plant fiber bags, and use environmentally friendly tape for sealing during the packaging process.

[0014] The present invention is further configured as follows: In the above S5, the natural plant fiber is bamboo fiber, hemp fiber, or flax fiber, and the length of the natural plant fiber is 5 mm - 8 mm, and the diameter of the natural plant fiber is 0.2 mm - 0.5 mm.

[0015] The present invention is further configured as follows: In the above S6, the dye is composed of plant extracts, mineral dyes, and water-based resin mixed in a mass ratio of 1:0.5:0.8.

[0016] The present invention is further configured such that: in S7, a bio-based glue is selected, and the bio-based glue is composed of the following components: 35% natural starch, 6% glycerin, 50% water, 6% natural gum, 1.5% sodium acetate, and 1.5% citric acid. Among them, the natural starch is corn starch, and the natural gum is gelatin or carrageenan.

[0017] The present invention is further configured such that: it further includes arranging a decorative edge strip around the furniture that has been connected. The edge strip is made of an environmentally friendly plastic material or recycled wood, and the color of the edge strip matches the main color of the furniture and is fixed to the furniture through a hot pressing process. The thickness of the edge strip is 3 mm - 6 mm, and the width is 10 mm - 25 mm.

[0018] The present invention is further configured such that: in S8, multiple detections include compressive strength detection, flexural strength detection, coating thickness detection, odor detection, and durability testing, and specifically include the following steps:

[0019] S81. Compressive strength detection:

[0020] Using an electronic universal testing machine to conduct a sampling compressive test on each batch of composite materials used to manufacture furniture components: First, conduct a preliminary screening. If the compressive strength is lower than 95% of the design standard, it is initially determined as unqualified. Secondly, select the weakest 10% of the samples initially determined as unqualified for a secondary test. Set the compressive threshold as A. If its compressive strength is lower than 0.5 MPa of A, then adjust the process conditions, including but not limited to adjusting the pressing temperature, pressing pressure, and pressing time. After the adjustment, conduct the test again. If it still cannot pass the design standard after the adjustment, then the batch needs to be reworked and the raw material selection and preparation steps need to be redone. After confirming that it meets the design standard through testing, proceed to the next step;

[0021] S82. Flexural strength detection:

[0022] Using the three-point bending test method to detect the flexural strength of the composite material: If the flexural strength of the composite material < 3 MPa, then it is determined that the batch of materials is unqualified, and composite materials with different ratios are used to reset the mixing ratio standard and conduct a secondary batch test until the flexural strength requirement is met; In addition, the thickness deviation of the composite material does not exceed ±0.3 mm, otherwise it will directly affect the flexural strength performance and the process conditions need to be adjusted immediately;

[0023] S83. Coating layer thickness detection:

[0024] Use a laser thickness gauge or an ultrasonic thickness gauge to detect the coating thickness. If the detected coating thickness is between 0.5 mm and 1.8 mm, it is determined that the coating meets the design standard; if the coating thickness < 0.5 mm, it is determined that the coating does not meet the design requirements and rework is immediately carried out; if the coating thickness > 1.8 mm, it is necessary to further judge whether the environmentally friendly coating is overused by combining the viscosity detection of the environmentally friendly coating. By detecting the ratio of the wet weight to the dry weight of the environmentally friendly coating, ensure that the actual usage amount of the environmentally friendly coating is controlled within the standard range. If the coating thickness continues to deviate from the design standard, it is necessary to adjust the formula of the environmentally friendly coating or repair it by rework, so as to meet the design standard.

[0025] S84, Odor detection:

[0026] Use a gas analyzer to detect the odor emission of furniture to ensure low VOC emission: Set the VOC threshold to 200 g / L - 300 g / L. By detecting the odor concentration of the furniture within 24 hours, if the VOC concentration > 300 g / L, it is determined to be unqualified, and optimize by adjusting the composition of the environmentally friendly coating or the mixing ratio of raw materials to ensure that the odor concentration is qualified; if the VOC concentration < 200 g / L or 200 g / L < VOC concentration < 300 g / L and not close to 300 g / L, it is determined to be qualified; if 200 g / L < VOC concentration < 300 g / L and close to 300 g / L, a second test is carried out, the specific components are analyzed, and combined with other components, including but not limited to formaldehyde content and benzene content, for comprehensive judgment; if the measured VOC concentration continues to be close to 300 g / L, optimize by adjusting the composition of the environmentally friendly coating or the mixing ratio of raw materials to ensure that the odor concentration is qualified.

[0027] S85, Durability test:

[0028] Carry out a long-term durability simulation experiment on the furniture, and use a thermal and humidity cycle test to detect the stability of the material: After 200 hours, if the deformation of the composite material > 5% and the expansion coefficient of the composite material > 3%, it is determined to be unqualified. Then for the unqualified products, re-prepare the composite material and adjust the parameters of the drying treatment step, and conduct the detection again after optimization until the detection is qualified.

[0029] The beneficial effects of the present invention are:

[0030] 1. Compared with the prior art, the furniture production method based on new environmentally friendly materials of the present invention uses environmentally friendly materials such as recycled wood, regenerated fiberboard, natural plant fibers, and degradable plastics, which can effectively reduce resource waste and environmental pollution during furniture production. Through the application of reasonable raw material ratios and composite processes, the final product not only has excellent physical properties but also ensures its environmental protection characteristics. Specifically, by using recycled wood and natural plant fibers, the consumption of forest resources is reduced, and degradable plastics are used to reduce long-term environmental pollution. At the same time, the use of environmentally friendly coatings and bio-based adhesives further improves the green characteristics of the product. In addition, through high-precision numerical control cutting and surface treatment processes, the high quality and long service life of the furniture can be guaranteed, achieving the goal of sustainable development.

[0031] 2. The furniture production method based on new environmentally friendly materials of the present invention can further enhance the environmental protection performance and mechanical properties of furniture materials by selecting natural plant fibers such as bamboo fibers, hemp fibers, or linen fibers and strictly controlling their length and diameter. Bamboo fibers and hemp fibers have good strength and toughness, which can effectively improve the tensile strength and bending strength of composite materials. The reasonable control of the length and diameter of the fibers can improve the bonding force between the fibers and the matrix and enhance the stability of the overall structure. In addition, natural plant fibers are rich in sources and renewable, are environmentally friendly, reduce the dependence on petrochemical resources, and conform to the trend of modern green production. Therefore, the use of composite materials with such natural plant fibers can not only meet the high-strength requirements of furniture but also reduce the negative impact on the environment.

[0032] 3. In the present invention, the dye is composed of plant extracts, mineral dyes, and water-based resins mixed in a specific ratio. This dye formulation ensures the uniformity and durability of the dyeing effect while maintaining high environmental protection. As a natural dye source, plant extracts not only have rich colors, are natural and non-toxic, but also have antioxidant and antibacterial properties, effectively improving the quality and use safety of furniture. The combination of mineral dyes and water-based resins can improve the adhesion and durability of the dye, so that the furniture surface remains beautiful for a longer time. In addition, the use of water-based resins reduces the emission of harmful substances that may exist in solvent-based dyes, further enhancing the environmental protection of the product. Therefore, the dye solution of the present invention not only ensures the appearance quality of the furniture but also improves its safety and environmental protection performance.

[0033] 4. In the present invention, a bio-based glue is adopted. The components are sourced from nature, conforming to the concept of green environmental protection. The natural starch, glycerol, natural gums, etc. used in the bio-based glue are not only renewable resources but also can effectively reduce environmental pollution during the production process. Compared with traditional chemical glues, the bio-based glue is safer and non-toxic, avoiding the release of harmful chemical substances. In particular, natural gum materials such as gelatin or carrageenan can not only provide a strong bonding effect but also improve the antibacterial and anti-corrosion properties of furniture to a certain extent, extending the service life of furniture. Therefore, using this bio-based glue not only improves the green environmental protection of furniture but also ensures its high efficiency, performance, and safety.

[0036] Refer to Figure 1-2 To further illustrate the embodiments of the furniture production method based on new environmentally friendly materials of the present invention.

[0037] For ease of explanation, in the embodiments, spatial relative terms such as "upper", "lower", "left", "right", etc. are used to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "lower" can include both the upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be correspondingly interpreted.

[0038] Moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0039] Figures 1 to 2 A furniture production method based on new environmentally friendly materials shown includes the following steps:

[0040] S1. Raw material selection and preparation: Select environmentally friendly materials, including recycled wood, recycled fiberboard, natural plant fibers, and degradable plastics. The mixing ratio is 40%-50% recycled wood, 20%-30% recycled fiberboard, 15%-20% natural plant fibers, and 5%-10% degradable plastics. Among them, the recycled wood should be decontaminated and ground into particles. The natural plant fibers and degradable plastics need to be dried and surface-treated to ensure the stability of their respective physical properties.

[0041] S2. Preparation of environmentally friendly composite materials: Open and uniformly mix the above raw materials in a mechanical manner according to the set ratio to obtain a mixed raw material. Then, subject the mixed raw material to high-temperature and high-pressure compounding to form an environmentally friendly composite material. The pressing temperature of the composite material is 120°C - 150°C, the pressing pressure is 5 MPa - 7 MPa, the pressing time is 10 min - 15 min, and the moisture content of the composite material is controlled to be <5% during the pressing process.

[0042] S3. Drying treatment: Dry the composite material through a hot air drying device. The drying temperature is 50°C - 100°C, and the drying time is 30 min - 60 min. After drying, the moisture content of the composite material is ≤2% to ensure the physical properties of the final product.

[0043] S4. Design and cutting of furniture components: According to the furniture design drawings, use a CNC cutting machine to precisely cut the composite material to obtain the required furniture components. The cutting size error is controlled within ±0.5 mm.

[0044] S5. Surface treatment and coating: Perform surface treatment on the cut furniture components, including but not limited to deburring and cleaning. Then, apply an environmentally friendly coating. The environmentally friendly coating consists of the following components: 30%-40% resin, 10%-15% inorganic filler, 20%-30% natural plant fibers, and 10%-20% natural rubber. Among them, the mass ratio of natural plant fibers to natural rubber is 60:40. After coating, cure the coating layer by heating. The curing temperature is 100°C - 120°C, the curing time is 30 min - 45 min, and the thickness of the coating layer is 0.5 mm - 1.8 mm.

[0045] In S5, the natural plant fibers are bamboo fibers, hemp fibers, or linen fibers, and the length of the natural plant fibers is 5 mm - 8 mm, and the diameter of the natural plant fibers is 0.2 mm - 0.5 mm.

[0046] By selecting natural plant fibers such as bamboo fibers, hemp fibers or linen fibers and strictly controlling their length and diameter, the environmental protection performance and mechanical properties of furniture materials can be further enhanced. Bamboo fibers and hemp fibers have good strength and toughness, which can effectively improve the tensile strength and bending strength of composite materials. The reasonable control of the length and diameter of the fibers can improve the bonding force between the fibers and the matrix and enhance the stability of the overall structure. In addition, natural plant fibers are rich in sources and renewable, environmentally friendly, reduce the dependence on petrochemical resources, and conform to the trend of modern green production. Therefore, the composite materials using such natural plant fibers can not only meet the high-strength requirements of furniture but also reduce the negative impact on the environment.

[0047] S6. Surface finishing: After the curing is completed, the surface of the furniture components is polished. The rotation speed of the polishing equipment is 800 rpm - 1200 rpm, and the polishing time is 10 min - 15 min to ensure a smooth surface. Then, a non-toxic and environmentally friendly dyeing treatment is carried out on the surface. The usage amount of the dye is 5% - 10% of the total mass of the composite material. The surface of the dyed furniture has uniform color and no obvious odor.

[0048] S7. Reinforcement and structural connection: The furniture components are reinforced and connected with environmentally friendly glue. The choices of glue include water-based glue or bio-based glue. The usage amount of the glue is 2% - 5% of the total mass of the components. The curing time of the glue is 2 h - 4 h to ensure that the glue is completely dried and cured without glue overflow. In addition, the connection methods of each furniture component are selected according to the design requirements, including but not limited to mortise and tenon connection, screw connection, and snap connection. The reinforced parts need to be ensured to be stable and without loosening.

[0049] S8. Finished product inspection: Multiple inspections are carried out on the furniture that has been connected to ensure compliance with the requirements.

[0050] S9. Finished product packaging: The furniture that has passed the inspection is packaged with environmentally friendly materials. The packaging materials include recyclable cardboard boxes or plant fiber bags, and the packaging process uses environmentally friendly tape for sealing.

[0051] Compared with the prior art, the furniture production method based on new environmentally friendly materials of the present invention uses environmentally friendly materials such as recycled wood, recycled fiberboard, natural plant fibers, and degradable plastics, which can effectively reduce resource waste and environmental pollution during furniture production. Through the application of reasonable raw material ratios and composite processes, the final product not only has excellent physical properties but also ensures its environmental protection characteristics. Specifically, by using recycled wood and natural plant fibers, the consumption of forest resources is reduced, and degradable plastics are used to reduce long-term environmental pollution. At the same time, the use of environmentally friendly coatings and bio-based adhesives further improves the green characteristics of the product. In addition, through high-precision numerical control cutting and surface treatment processes, the high quality and long service life of the furniture can be guaranteed, achieving the goal of sustainable development.

[0052] In S6, the dye is composed of plant extracts, mineral dyes, and water-based resin mixed in a mass ratio of 1:0.5:0.8.

[0053] In the present invention, the dye is composed of plant extracts, mineral dyes, and water-based resin mixed in a specific ratio. This dye formulation ensures the uniformity and durability of the dyeing effect while maintaining high efficiency and environmental protection. As a natural dye source, plant extracts not only have rich colors, are natural and non-toxic, but also have antioxidant and antibacterial properties, effectively improving the quality and use safety of the furniture. The combination of mineral dyes and water-based resin can improve the adhesion and durability of the dye, so that the furniture surface remains beautiful for a longer time. In addition, the use of water-based resin reduces the emission of harmful substances that may exist in solvent-based dyes, further enhancing the environmental protection of the product. Therefore, the dye solution of the present invention not only ensures the appearance quality of the furniture but also improves its safety and environmental protection performance.

[0054] In S7, a bio-based adhesive is selected. The bio-based adhesive is composed of the following components: 35% natural starch, 6% glycerol, 50% water, 6% natural gum, 1.5% sodium acetate, and 1.5% citric acid. Among them, the natural starch is corn starch, and the natural gum is gelatin or carrageenan.

[0055] Using a bio-based adhesive, the component sources are natural, which conforms to the concept of green environmental protection. The components such as natural starch, glycerol, and natural gum used in the bio-based adhesive are not only renewable resources but also can effectively reduce environmental pollution during the production process. Compared with traditional chemical adhesives, the bio-based adhesive is safer and non-toxic, avoiding the release of harmful chemical substances. In particular, natural gum materials such as gelatin or carrageenan can not only provide a strong bonding effect but also improve the antibacterial and anti-corrosion properties of the furniture to a certain extent, extending the service life of the furniture. Therefore, using this bio-based adhesive not only improves the green environmental protection of the furniture but also ensures its high efficiency, performance, and safety.

[0056] It also includes setting decorative edging strips around the furniture that has been connected. The edging strips are made of environmentally friendly plastic materials or recycled wood, and the color of the edging strips matches the main color of the furniture and is fixed to the furniture through a hot pressing process. The thickness of the edging strips is 3mm - 6mm, and the width is 10mm - 25mm;

[0057] By setting decorative edging strips around the furniture, not only the appearance design of the furniture is improved, but also the safety, durability and beauty of the furniture are increased. The selected environmentally friendly plastic materials or recycled wood have good physical properties and durability, which can effectively avoid the furniture being knocked and damaged during use. At the same time, the matching of the edging strips with the main color of the furniture can enhance the overall visual effect of the furniture, making it more beautiful and modern. In addition, the hot pressing process firmly fixes the edging strips to the furniture, ensuring that the decorative edging strips are not easily detached or deformed, and improving the structural stability and reliability of the furniture for long-term use. In summary, the setting of the edging strips not only has decorative properties, but also improves the durability and use value of the furniture.

[0058] In S8, the multiple detections include compressive strength detection, flexural strength detection, coating thickness detection, odor detection and durability test, which specifically include the following steps:

[0059] S81. Compressive strength detection:

[0060] Use an electronic universal testing machine to conduct sampling compressive tests on each batch of composite materials used to manufacture furniture components: First, conduct a preliminary screening. If the compressive strength is lower than 95% of the design standard, it is initially determined to be unqualified; Second, select the weakest 10% of the samples initially determined to be unqualified for a second test, set the compressive threshold as A. If its compressive strength is lower than 0.5MPa of A, then adjust the process conditions, including but not limited to adjusting the pressing temperature, pressing pressure and pressing time. After the adjustment is completed, conduct the test again. If it still cannot pass the design standard after the adjustment, the batch needs to be reworked and the raw material selection and preparation steps need to be redone. After confirming that it meets the design standard through testing, proceed to the next step;

[0061] S82. Flexural strength detection:

[0062] Use the three-point bending test method to detect the bending strength of the composite material: If the bending strength of the composite material < 3MPa, it is determined that the batch of materials is unqualified, and use composite materials with different ratios, reset the mixing standard, and conduct a second batch test until the bending strength requirement is met; In addition, the thickness deviation of the composite material does not exceed ±0.3mm, otherwise it will directly affect the flexural strength performance and the process conditions need to be adjusted immediately;

[0063] S83. Coating layer thickness detection:

[0064] Use a laser thickness gauge or an ultrasonic thickness gauge to detect the coating thickness. If the detected coating thickness is between 0.5 mm and 1.8 mm, it is determined that the coating meets the design standard; if the coating thickness < 0.5 mm, it is determined that the coating does not meet the design requirements and rework is immediately carried out; if the coating thickness > 1.8 mm, it is necessary to combine the viscosity detection of the environmentally friendly coating to further determine whether the environmentally friendly coating is overused. By detecting the ratio of the wet weight to the dry weight of the environmentally friendly coating, ensure that the actual usage amount of the environmentally friendly coating is controlled within the standard range. If the coating thickness continues to deviate from the design standard, it is necessary to adjust the formula of the environmentally friendly coating or repair it through rework to meet the design standard.

[0065] S84, Odor Detection:

[0066] Use a gas analyzer to detect the odor emissions of furniture to ensure low VOC emissions: Set the VOC threshold to 200 g / L - 300 g / L. By detecting the odor concentration of the furniture within 24 hours, if the VOC concentration > 300 g / L, it is determined to be unqualified, and optimize by adjusting the composition of the environmentally friendly coating or the mixing ratio of raw materials to ensure that the odor concentration is qualified; if the VOC concentration < 200 g / L or 200 g / L < VOC concentration < 300 g / L and not close to 300 g / L, it is determined to be qualified; if 200 g / L < VOC concentration < 300 g / L and close to 300 g / L, conduct a second test, analyze the specific components, and make a comprehensive judgment in combination with other components, including but not limited to formaldehyde content and benzene content; if the tested VOC concentration continues to be close to 300 g / L, optimize by adjusting the composition of the environmentally friendly coating or the mixing ratio of raw materials to ensure that the odor concentration is qualified.

[0067] S85, Durability Test:

[0068] Conduct a long-term durability simulation experiment on the furniture and use a thermal and humidity cycle test to detect the stability of the materials: After 200 hours, if the deformation of the composite material > 5% and the expansion coefficient of the composite material > 3%, it is determined to be unqualified. Then, for unqualified products, re-prepare the composite material and adjust the parameters of the drying process step, and conduct the detection again after optimization until the detection is qualified.

[0069] Multiple detection measures of the present invention ensure that the produced furniture meets strict quality standards. Multiple quality control means such as compressive strength detection, flexural strength detection, coating thickness detection, etc. can effectively identify and eliminate unqualified materials or products, ensuring that the furniture has good mechanical properties and durability. In particular, the compressive strength detection and flexural strength detection can effectively avoid potential safety hazards caused by structural problems of the furniture, and the coating thickness detection can ensure the uniformity and environmental protection of the environmentally friendly coating. The odor detection ensures low VOC emissions of the furniture, and the durability test further verifies the stability of the furniture during long-term use. Through these strict detection measures, it can be ensured that the final product not only meets the environmental protection standards, but also has high quality and long service life, thus greatly improving the market competitiveness of the product and the satisfaction of consumers.

[0070] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.

6. A furniture production method based on a new type of environmentally friendly material according to claim 1, characterized in that, In S8, the multiple inspections include compressive strength inspection, flexural strength inspection, coating thickness inspection, odor inspection and durability test, and specifically include the following steps: S81, Compressive Strength Inspection: Use an electronic universal testing machine to conduct sampling compressive tests on the composite materials used for manufacturing furniture components in each batch: First, conduct a preliminary screening. If the compressive strength is lower than 95% of the design standard, it is initially judged as unqualified; Second, select the weakest 10% of the samples initially judged as unqualified for a second test, set the compressive threshold as A. If its compressive strength is lower than 0.5MPa of A, then adjust the process conditions, including but not limited to adjusting the pressing temperature, pressing pressure and pressing time. After the adjustment is completed, conduct the test again. If it still cannot pass the design standard after the adjustment, the batch needs to be reworked and the raw material selection and preparation steps need to be redone. After confirming that it meets the design standard through inspection, proceed to the next step; S82, Flexural Strength Inspection: Use the three-point bending test method to detect the bending strength of the composite material: If the bending strength of the composite material < 3MPa, it is determined that the batch of materials is unqualified, and the composite materials with different ratios are used to reset the mixing standard and conduct a second batch test until the bending strength requirement is met; In addition, the thickness deviation of the composite material does not exceed ±0.3mm, otherwise it will directly affect the flexural strength performance and the process conditions need to be adjusted immediately; S83, Coating Layer Thickness Inspection: Use a laser thickness gauge or an ultrasonic thickness gauge to detect the coating thickness. If the detected coating thickness is between 0.5 mm and 1.8 mm, it is determined that the coating meets the design standard; if the coating thickness < 0.5 mm, it is determined that the coating does not meet the design requirements and rework is immediately carried out; if the coating thickness > 1.8 mm, it is necessary to combine the viscosity detection of the environmentally friendly coating to further determine whether the environmentally friendly coating is overused. By detecting the ratio of the wet weight to the dry weight of the environmentally friendly coating, ensure that the actual usage amount of the environmentally friendly coating is controlled within the standard range. If the coating thickness continues to deviate from the design standard, it is necessary to adjust the formula of the environmentally friendly coating or repair it through rework so as to meet the design standard. S84, Odor detection: Use a gas analyzer to detect the odor emission of the furniture to ensure low VOC emission: Set the VOC threshold to 200 g / L - 300 g / L. By detecting the odor concentration of the furniture within 24 hours, if the VOC concentration > 300 g / L, it is determined to be unqualified, and optimize by adjusting the composition of the environmentally friendly coating or the mixing ratio of raw materials to ensure that the odor concentration is qualified; if the VOC concentration < 200 g / L or 200 g / L < VOC concentration < 300 g / L and not close to 300 g / L, it is determined to be qualified; if 200 g / L < VOC concentration < 300 g / L and close to 300 g / L, a second test is carried out to analyze the specific components and make a comprehensive judgment in combination with other components, including but not limited to formaldehyde content and benzene content. If the tested VOC concentration continues to be close to 300 g / L, optimize by adjusting the composition of the environmentally friendly coating or the mixing ratio of raw materials to ensure that the odor concentration is qualified. S85, Durability test: Conduct a long-term durability simulation experiment on the furniture and use a thermal and humidity cycle test to detect the stability of the material: After 200 h, if the deformation of the composite material > 5% and the expansion coefficient of the composite material > 3%, it is determined to be unqualified. Then for the unqualified products, re-prepare the composite material and adjust the parameters of the drying treatment step, and conduct the detection again after optimization until the detection is qualified.
