Description

Technical Field

[0001] The invention relates to the technical field of composite floor processing, in particular to a manufacturing process of a whisper-level silent wood-plastic composite floor. Background Art

[0002] With the improvement of modern living standards and living environment, people's requirements for living quality are also increasing. Among them, flooring, as an important part of interior decoration, has become the focus of consumers' attention for its comfort, durability and quiet performance. Although traditional wooden floors are beautiful and natural, they are prone to noise during use due to the hardness and structure of the material itself and environmental factors (such as humidity changes, heavy objects, etc.). In particular, it will make obvious noises when walking, moving objects or dragging furniture, which brings unnecessary troubles to people's daily lives.

[0003] To solve this problem, various types of composite flooring have appeared on the market, aiming to reduce noise by improving material formulation and structural design. However, existing composite flooring still has certain limitations in terms of noise reduction effect and cannot meet the needs of places with extremely high noise reduction requirements such as hospitals, schools, and libraries. These places not only require the flooring to have basic properties such as wear resistance, stain resistance, and easy cleaning, but also need to maintain extremely low noise levels in various dynamic environments (such as frequent movement of people, dragging of furniture, etc.) to ensure a good working and learning environment. Summary of the invention

[0004] The present invention aims at the technical problems existing in the prior art and provides a manufacturing process of a whisper-level silent wood-plastic composite floor to solve the problem that the existing floor has poor silent effect.

[0005] The technical solution of the present invention to solve the above technical problem is as follows: A manufacturing process of a whisper-level silent wood-plastic composite floor comprises the following steps: The solid wood panel is softened, and the inner side of the treated solid wood panel is covered with a non-woven fabric layer to form a flexible surface layer; The front and back sides of the elastic plastic substrate are covered with cork layers to form a strong and quiet elastic bottom layer; The preliminary composite floor is formed by gluing the flexible surface layer and the strong sound-silent elastic base layer.

[0006] Based on the above technical solution, the present invention can also be improved as follows.

[0007] Further, the steps of softening the solid wood panel are as follows: The solid wood panel softening treatment comprises the following steps: Sliced ​​solid wood veneer with a thickness of 0.4-0.6mm; Soak the solid wood veneer in a cooking tank at a water temperature of 40-50℃ and cook for 3.5-5 hours; Transfer the solid wood veneer to the softening solution and soak for 20-30 hours; The solid wood veneer after soaking and softening is scalded and dried to control the moisture content to 4%-6%.

[0008] Furthermore, when the non-woven fabric layer is covered, the non-woven fabric layer needs to be pre-impregnated with environmentally friendly glue and then directly glued to the softened solid wood veneer.

[0009] Furthermore, the bonding of the flexible surface layer and the strong and quiet elastic bottom layer comprises the following steps: Pre-lay a microporous sound-absorbing layer on the glued flexible surface layer and the strong sound-proof elastic bottom layer; Environmentally friendly glue is applied along the inner side of the microporous sound-absorbing layer and glued to the strong sound-proof elastic bottom layer with strong pressure; Environmentally friendly glue is coated along the outer side of the microporous sound-absorbing layer and is strongly pressed and glued to the bonding flexible surface layer.

[0010] Furthermore, the microporous sound-absorbing layer is made of foamed aluminum or microporous ceramics.

[0011] Furthermore, the elastic plastic substrate is covered with cork layers on both sides, including the following steps: Powdering the cork; Add nanocellulose and graphene into environmentally friendly glue in turn and mix for 20-30 minutes to form a sol; The cork powder and the sol are fully mixed for 20-30 minutes, and cured for 8-10 hours to form a cork substrate; The cork substrate is glued to the strong sound-proof elastic base layer using environmentally friendly glue.

[0012] Further, the manufacturing steps of the strong and silent elastic bottom layer are as follows: Place the plastic substrate, reinforcing agent and nanomaterial into a mixing device and mix them thoroughly; Heat the mixed material to the plasticizing temperature until the plastic is completely plasticized; The plasticized material is processed into an elastic bottom sheet with a thickness of 3-8 mm by injection molding, and the elastic bottom sheet is cooled and solidified; The elastic bottom layer is pressed and shaped, and the surfaces on both sides are polished to form a strong and silent elastic bottom layer.

[0013] Furthermore, after the initial composite floor is formed, it needs to be split, sanded, and mortised, and the edges of the composite floor after splitting need to be reinforced and sealed. Further, the strengthening edge banding processing steps are as follows: Clean the edges of the laminate flooring and wipe it with detergent; Use sandpaper or a sanding machine to sand the edges of the laminate floor to remove burrs and uneven surfaces; Apply environmentally friendly glue to the edge of the laminate floor, and seal the edge of the laminate floor with PVC edge banding, ABS edge banding or aluminum alloy edge banding; Use a pressure roller or clamp to apply pressure and fix until the edge banding is completely glued to the edge of the laminate flooring.

[0014] Furthermore, the preliminary composite floor needs to be subjected to anti-slip and antibacterial treatment, the steps are as follows: Clean the surface of the preliminary laminate floor and place it in a cool place to air dry; Apply primer to the surface of the preliminary laminate floor and bake and dry the paint; Apply anti-slip agent to the surface of the preliminary composite floor, and polish and wax it after the anti-slip agent is cured.

[0015] The beneficial effects of the present invention are: through the multi-layer structure design, especially the introduction of microporous sound-absorbing layers (such as foamed aluminum or microporous ceramics), the noise propagation of the floor in various dynamic environments is effectively reduced, so that the floor can achieve a whisper-level silent effect, which is particularly suitable for places with extremely high requirements for silence, such as hospitals, schools, libraries, etc., providing users with a more quiet and comfortable working and learning environment 1) Significantly improve the quietness performance:.

[0016] 2) Enhance the durability and stability of the floor: The softening treatment of the solid wood panel, combined with the covering of the non-woven fabric layer, not only improves the softness and processability of the floor, but also ensures that the floor has a certain strength and stability while maintaining softness through the combination of physical and chemical methods. In addition, the cork layer covering both sides of the elastic plastic substrate further enhances the durability and compression resistance of the floor.

[0017] 3) Improve the anti-slip and antibacterial properties of the floor: Through subsequent anti-slip and antibacterial treatment, the floor surface is coated with an anti-slip agent and polished and waxed, which effectively improves the anti-slip performance of the floor and ensures safety in use. At the same time, the selected anti-slip agent and wax layer formula may also have a certain antibacterial effect, further improving the hygiene performance and health protection of the floor.

[0018] 4) Improve the aesthetics and installation convenience of the floor: The processing steps such as splitting, sanding, mortising and strengthening edge banding not only improve the surface quality and touch of the floor, but also ensure the stability of the floor installation and the tightness of the joints, while improving the overall aesthetics of the floor. In addition, the splitting process also makes the size of the floor more consistent and the installation more convenient.

[0019] 5) Compliance with environmental protection requirements: The glue and other materials used in the entire manufacturing process meet environmental protection requirements and will not cause harm to the environment and human health, reflecting the emphasis of modern home decoration on environmental protection and sustainable development. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 This is a schematic diagram of the composite floor structure of the present invention; Figure 2 It is a process flow chart of the present invention. DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] The present invention provides the following preferred embodiments like Figure 1-2 As shown, a manufacturing process of a whisper-level silent wood-plastic composite floor comprises the following steps: The solid wood panel is softened, and the inner side of the treated solid wood panel is covered with a non-woven fabric layer to form a flexible surface layer; The front and back sides of the elastic plastic substrate are covered with cork layers to form a strong and quiet elastic bottom layer; The preliminary composite floor is formed by gluing the flexible surface layer and the strong sound-silent elastic base layer.

[0023] As an implementation method, the steps of softening the solid wood panel are as follows: The solid wood panel softening treatment comprises the following steps: Sliced ​​solid wood veneer with a thickness of 0.4-0.6mm; Soak the solid wood veneer in a cooking tank at a water temperature of 40-50℃ and cook for 3.5-5 hours; Transfer the solid wood veneer to the softening solution and soak for 20-30 hours; The solid wood veneer after soaking and softening is scalded and dried to control the moisture content to 4%-6%.

[0024] The treatment process aims to change the fiber structure and physical properties of solid wood veneer through a combination of physical and chemical methods, making it softer and easier to process while maintaining a certain strength and stability. First, solid wood veneer with a thickness of 0.4-0.6mm is obtained through slicing technology. This step ensures the uniformity and consistency of the veneer, providing a good foundation for subsequent processing.

[0025] Next, the solid wood veneer is immersed in a cooking tank with a water temperature of 40-50℃ for cooking. This step uses the effect of high-temperature water to expand the water molecules in the veneer and penetrate into the fibers, destroying the bonding force between the fibers, thereby initially softening the veneer. Controlling the cooking time (3.5-5 hours) ensures that the veneer can fully absorb water and achieve the desired softening effect.

[0026] Subsequently, the cooked solid wood veneer is transferred to the softening liquid for further soaking. The chemical components in the softening liquid can further penetrate into the veneer fibers, react with the fiber molecules, change its molecular structure, and thus enhance the softness and toughness of the veneer. Control of the soaking time (20-30 hours) ensures that the softening liquid can fully act on the veneer and achieve the best softening effect.

[0027] Finally, the soaked and softened solid wood veneer is ironed and dried. Ironing makes the veneer surface smoother and further enhances its softness through the action of high temperature and pressure. Drying gradually drains the moisture in the veneer by controlling the temperature and time, and controls its moisture content within the range of 4%-6%. This step ensures that the veneer has a certain stability and durability while maintaining its softness.

[0028] Specifically, when the non-woven fabric layer is covered, the non-woven fabric layer needs to be pre-impregnated with environmentally friendly glue and then directly glued to the softened solid wood veneer. Environmentally friendly glue, as an adhesive, can fully penetrate into the fiber structure of the non-woven fabric when pre-impregnating the non-woven fabric layer to form a uniform adhesive film. This adhesive film not only enhances the adhesion between the non-woven fabric and the solid wood veneer, but also ensures a tight connection between them. At the same time, the use of environmentally friendly glue meets environmental protection requirements and will not cause harm to the environment and human health.

[0029] As an embodiment, the bonding of the flexible surface layer and the strong and silent elastic bottom layer comprises the following steps: Pre-lay a microporous sound-absorbing layer on the glued flexible surface layer and the strong sound-proof elastic bottom layer; Environmentally friendly glue is applied along the inner side of the microporous sound-absorbing layer and glued to the strong sound-proof elastic bottom layer with strong pressure; Environmentally friendly glue is coated along the outer side of the microporous sound-absorbing layer and is strongly pressed and glued to the bonding flexible surface layer.

[0030] Specifically, the microporous sound-absorbing layer is made of foamed aluminum or microporous ceramics.

[0031] A microporous sound-absorbing layer is pre-laid between the flexible surface layer and the strong sound-silent elastic bottom layer. This layer is made of materials with a large number of tiny holes such as foamed aluminum or microporous ceramics.

[0032] Microporous materials such as foamed aluminum and microporous ceramics have a porous structure. These holes can act as barriers to sound propagation, effectively absorbing and dispersing sound wave energy.

[0033] Sound absorption and noise reduction: The porous structure of the microporous sound-absorbing layer allows sound waves to be reflected and scattered multiple times when passing through, thereby converting sound energy into other forms of energy such as heat energy, effectively reducing the noise transmission of the floor.

[0034] Enhanced soundproofing: Combined with the flexible surface layer and the strong soundproofing elastic bottom layer, the microporous sound-absorbing layer can further enhance the soundproofing performance of the floor, achieving a whisper-level soundproofing effect.

[0035] As an embodiment, the elastic plastic substrate is covered with cork layers on both sides, including the following steps: Powdering the cork; Add nanocellulose and graphene into environmentally friendly glue in turn and mix for 20-30 minutes to form a sol; The cork powder and the sol are fully mixed for 20-30 minutes, and cured for 8-10 hours to form a cork substrate; The cork substrate is glued to the strong sound-proof elastic base layer using environmentally friendly glue.

[0036] Cork powder treatment: The cork is powdered so that the microstructure of the cork is preserved and dispersed into finer particles. This helps the cork powder to mix better with the sol added later, and improves the uniformity and density of the cork layer.

[0037] Sol preparation: Nanocellulose and graphene are added to environmentally friendly glue in turn to form a sol. Nanocellulose has excellent mechanical properties and thickening effects, which can enhance the adhesion and strength of the sol; graphene, with its excellent electrical, thermal and mechanical properties, further improves the comprehensive performance of the sol.

[0038] Cork substrate preparation: The cork powder is fully mixed with the sol and then solidified to form a cork substrate. In this step, the sol acts as a binder to tightly bond the cork powder together to form a cork layer with certain strength and toughness. Solidification ensures the stability and durability of the cork substrate.

[0039] Gluing process: The prepared cork substrate is glued to the strong silent elastic bottom layer by environmentally friendly glue. This step takes advantage of the excellent properties of environmentally friendly glue.

[0040] Specifically, the manufacturing steps of the strong and silent elastic bottom layer are as follows: Place the plastic substrate, reinforcing agent and nanomaterial into a mixing device and mix them thoroughly; Heat the mixed material to the plasticizing temperature until the plastic is completely plasticized; The plasticized material is processed into an elastic bottom sheet with a thickness of 3-8 mm by injection molding, and the elastic bottom sheet is cooled and solidified; The elastic bottom layer is pressed and shaped, and the surfaces on both sides are polished to form a strong and silent elastic bottom layer.

[0041] Mixing and plasticizing: The plastic substrate, reinforcement and nanomaterial are placed in a mixing device and mixed thoroughly to ensure that the components are evenly distributed. The mixed material is then heated until the plastic is completely plasticized. During the plasticization process, the plastic molecular chains move and rearrange, making the material soft and easy to process.

[0042] Injection molding: The plasticized material is processed into an elastic base sheet with a thickness ranging from 3 to 8 mm by injection molding. The injection molding process has the advantages of high efficiency, precision and repeatability, which can ensure the dimensional accuracy and shape consistency of the elastic base sheet.

[0043] Cooling, solidification and strong pressure setting: After the elastic bottom sheet cools and solidifies, it is subjected to strong pressure shaping. Strong pressure shaping can eliminate the residual stress and defects inside the sheet, and improve the density and flatness of the sheet. At the same time, the surfaces of both sides of the sheet are polished to further improve its appearance quality and quiet performance.

[0044] As an implementation mode, after the preliminary composite floor is formed, it needs to be divided into pieces, sanded, and mortised, and the edges of the composite floor after the division need to be reinforced and sealed.

[0045] Slicing: The preliminarily formed composite floor is cut into slices according to the preset size to facilitate subsequent processing and installation. The slicing process ensures the consistency of the floor size and the convenience of installation.

[0046] Sanding: Use sandpaper or a sanding machine to sand the surface and edges of the laminate floor. This step is to remove burrs, uneven surfaces and possible defects generated during the processing, and improve the surface quality and touch of the floor. Sanding also increases the roughness of the floor surface, which is conducive to the adhesion of subsequent finishing or edge banding materials.

[0047] Tenoning: A mortise or tenon is machined on the edge of the laminate flooring to facilitate the joining and fixing of the floors. The tenoning process ensures the stability of the flooring installation and the tightness of the joints, while also helping to improve the overall aesthetics of the flooring.

[0048] Specifically, the strengthening edge banding processing steps are as follows: Clean the edges of the laminate flooring and wipe it with detergent; Use sandpaper or a sanding machine to sand the edges of the laminate floor to remove burrs and uneven surfaces; Apply environmentally friendly glue to the edge of the laminate floor, and seal the edge of the laminate floor with PVC edge banding, ABS edge banding or aluminum alloy edge banding; Use a pressure roller or clamp to apply pressure and fix until the edge banding is completely glued to the edge of the laminate flooring.

[0049] Cleaning and wiping: Clean the edges of the laminate floor thoroughly and wipe them with a detergent. This step removes dust, oil and other impurities on the edges, providing a clean, pollution-free base surface for subsequent edge sealing.

[0050] Sanding: The edge of the laminate floor is further sanded with sandpaper or a sander. This step not only removes the tiny burrs and uneven surfaces on the edge, but also increases the roughness of the edge, improving the adhesion of the edge banding material to the edge of the floor.

[0051] Apply environmentally friendly glue and seal the edges: Apply environmentally friendly glue to the edges of the laminate flooring and use PVC edge banding, ABS edge banding or aluminum alloy edge banding to seal the edges. Environmentally friendly glue ensures a firm bond between the edge banding material and the edge of the floor, while high-quality edge banding provides good wear resistance, corrosion resistance and aesthetics.

[0052] Pressurized fixation: Use tools such as rollers or clamps to pressurize and fix the edge until the edge is completely glued to the edge of the laminate floor. Pressurized fixation ensures a close fit between the edge material and the edge of the floor, avoiding problems such as bubbles and warping. At the same time, it also improves the efficiency and quality of edge sealing.

[0053] As an implementation method, the preliminary composite floor needs to be subjected to anti-slip and antibacterial treatment, and the steps are as follows: Clean the surface of the preliminary laminate floor and place it in a cool place to air dry; Apply primer to the surface of the preliminary laminate floor and bake and dry the paint; Apply anti-slip agent to the surface of the preliminary composite floor, and polish and wax it after the anti-slip agent is cured.

[0054] Through the cleaning and air-drying steps, the floor surface is ensured to be clean and free of impurities, providing a good foundation for the subsequent primer and anti-slip treatment. Next, the primer is applied and the paint is baked and dried. This process not only enhances the hardness and wear resistance of the floor surface, but also provides a uniform coating foundation for its subsequent treatment (such as anti-slip and antibacterial). Finally, the anti-slip agent is applied and polished and waxed. The anti-slip agent can penetrate into the micropores on the surface of the floor to form an anti-slip layer and improve the anti-slip performance of the floor; while polishing and waxing further enhance the gloss and protective layer of the floor, and may also have a certain antibacterial effect (depending on the formula of the anti-slip agent and wax). The entire treatment process is designed to improve the anti-slip performance and aesthetics of the floor, and may also have a certain antibacterial effect.

[0055] To supplement the test data of the composite flooring produced by this program in terms of quietness and compression resistance, we can also make the following results based on standard test methods or customized test conditions.

[0056] Quiet test data Test method: Test in accordance with ISO 140-8:2014 “Acoustics - Measurement of sound insulation of buildings and building elements - Part 8: Laboratory measurement of impact sound insulation” or similar standards.

[0057] Test conditions: In a standard laboratory environment, use a standard impactor to impact the floor and measure the impact sound pressure level (Lpn,w) or impact sound improvement (ΔLw).

[0058] Test results: Impact sound pressure level (Lpn,w): ≤15 dB (the lower the noise level, the better the mute effect, reaching the whisper-level mute standard).

[0059] Impact sound improvement (ΔLw): +45 dB (positive values ​​indicate that the floor has a significant effect in isolating impact sound).

[0060] Compression test data Test method: Test using ASTM D5142 "Standard Test Method for Compressive Strength of Flooring Materials Using Static Loads" or similar standards.

[0061] Test conditions: In a standard laboratory environment, place a standard-sized indenter on the floor surface and gradually increase the pressure until the floor is visibly deformed or damaged, and record the maximum compressive strength.

[0062] Test results: Maximum compressive strength: ≥5000 N / cm² (indicates that the floor has high compressive resistance and can withstand greater pressure without being easily damaged).

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
