Description

Technical Field

[0001] The present invention relates to the technical field of composite plate processing, and more specifically, to a composite plate multilayer structure and a processing method thereof. Background Art

[0002] Composite panels are a type of panel made of two or more different materials. They have the advantages of each layer of material and are widely used in the fields of construction, aerospace, automobiles, ships, etc. Common composite panel structures include a combination of glass fiber, carbon fiber, metal, wood and other materials, which are stacked together by adhesives or other connection methods to obtain superior performance than a single material, such as higher strength, stiffness, corrosion resistance and lightweight characteristics.

[0003] Although the existing composite board technology has made significant progress in improving material performance, there are still some technical problems that need to be solved, such as insufficient interface bonding strength and insufficient bonding strength between the layers of materials, which leads to problems such as stratification and delamination of the composite board during use, affecting the stability and service life of the overall structure. The manufacturing process is complex. The manufacturing process of the composite board involves a variety of materials and processes, such as hot pressing, lamination, gluing, etc. The process is complex, the production cost is high, and the production efficiency is low. Quality control is difficult. Due to the multi-layer structure of the composite board, quality problems such as uneven thickness, bubbles, and impurities are prone to occur during the production process, which makes detection and control difficult. Material selection and optimization are difficult. The selection and optimization of each layer of materials need to comprehensively consider multiple factors such as their mechanical properties, physical properties, and chemical stability. The interactions between materials are complex, and the optimization settings are difficult. Environmental impact and sustainability issues. The adhesives and other chemicals used in the production process of composite boards may have adverse effects on the environment, are difficult to recycle and reuse, and there are sustainability issues.

[0004] At present, the most common composite panels in life are floors. After water is sprinkled on the surface of existing composite floor, the water is transparent and difficult to detect after contact with the floor, which can easily cause users to slip. In addition, existing composite floor cannot absorb or dry water quickly. Over time, the part in contact with water is prone to mold and blackening, which affects the overall appearance and reduces the use effect and life of the composite board.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a composite plate multilayer structure and a processing method thereof. Summary of the invention

[0006] The object of the present invention is to provide a composite board multilayer structure and a processing method thereof to solve the above-mentioned problems.

[0007] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows: A composite board multilayer structure comprises a wear-resistant layer, a water absorbing layer is fixedly connected to the lower end of the wear-resistant layer, a self-heating layer is fixedly connected to the lower end of the water absorbing layer, a substrate layer is fixedly connected to the lower end of the self-heating layer, and a balancing layer is fixedly connected to the lower end of the substrate layer. Through the arrangement of the multilayer structure, the overall structure provides good anti-slip, water absorption, self-heating and structural stability, meeting the use requirements in various environments.

[0008] As a further improvement of the present invention, a plurality of evenly distributed grooves are provided at the upper end of the wear-resistant layer, and a swelling block is fixedly connected in the groove. The swelling block in the groove expands when it meets water to form a convex structure, which significantly enhances the anti-slip performance of the composite board and prevents slipping accidents.

[0009] As a further improvement of the present invention, the swelling block includes swelling particles, which are embedded in the inner end of the groove, and the upper end of the swelling particles is fixedly connected to a moisture-sensitive sheet, and the upper inner wall of the groove is fixedly connected to a retractable film, and the retractable film is located at the upper end of the moisture-sensitive sheet, and the outer end of the moisture-sensitive sheet is fixedly connected to a water-absorbing fiber, and the water-absorbing fiber penetrates the wear-resistant layer. Through the arrangement of the retractable film and the swelling particles, the swelling block can, when encountering water, drain moisture to the moisture-sensitive sheet through the water-absorbing fiber, causing it to change color and causing the swelling particles to expand rapidly and form an anti-slip structure, and at the same time restore its original state after drying, ensuring repeated use and long-term anti-slip effect.

[0010] As a further improvement of the present invention, the expansion particles are made of shape memory polymer material, the moisture sensitive sheet is made of humidity sensitive material, the humidity sensitive material changes color when exposed to water, and the retractable membrane is made of elastic material, which is a transparent elastic waterproof and breathable membrane.

[0011] As a further improvement of the present invention, the wear-resistant layer includes two composite-formed identical solid wood boards, and the water-absorbing fibers are located between the two solid wood boards and form a mesh structure therebetween.

[0012] As a further improvement of the present invention, the water-absorbing layer is made of a highly water-absorbent polymer material, which can quickly absorb moisture from the ground and keep the surface dry, thereby greatly improving the water absorption and anti-slip properties of the composite board.

[0013] As a further improvement of the present invention, the self-heating layer is made of hygroscopic and heat-generating material, which is beneficial for the hygroscopic and heat-generating material to release heat while absorbing moisture, accelerate moisture evaporation, keep the ground dry, and improve the comfort and safety of the use environment.

[0014] As a further improvement of the present invention, the substrate layer is made of high-density fiberboard, and the balancing layer is made of moisture-proof material. The high-density fiberboard provides good structural strength and stability, and the balancing layer of moisture-proof material prevents moisture penetration, ensuring that the composite board will not deform during long-term use, thereby improving the durability and reliability of the product.

[0015] A method for processing a composite plate multilayer structure comprises the following steps: S1. Select appropriate high-density fiberboard, carry out moisture-proof treatment, cutting and processing; S2, compounding the wear-resistant layer, the water-absorbing layer, the self-heating layer, the base material layer and the balance layer by hot pressing gluing or riveting; S3, embossing and polishing the surface of the wear-resistant layer, and chiseling out a plurality of evenly distributed grooves; S4, embed the swelling block into the groove and seal the groove; S5. Finally, the composite board is grooved and chamfered, and the quality of the finished composite board is inspected; The high-density fiberboard is treated with moisture-proof treatment to ensure the durability and moisture resistance of the base material. The layers are firmly combined through a composite molding process such as hot pressing, gluing or riveting to ensure the overall strength of the composite board. The wear-resistant layer is embossed and polished, and swelling blocks made of shape memory polymer are embedded in the surface grooves to significantly enhance the anti-slip performance. The final grooving and chamfering treatment improves the safety and aesthetics of the product, ensuring the high performance, long life and applicability of the composite board as a whole.

[0016] Compared with the prior art, the advantages of the present invention are: This solution significantly improves the anti-slip performance by forming raised particles on the wear-resistant layer after the swelling blocks come into contact with water, ensuring the safety of users in slippery environments. The color-changing function of the moisture-sensing sheet can quickly remind users that there is water on the ground to prevent accidental slips. The efficient water-absorbing layer and the self-heating layer can achieve rapid water absorption and rapid drying to keep the ground dry. The wear-resistant layer and the swelling particles are made of wear-resistant and tear-resistant materials to ensure durability during long-term use. The application of smart materials, such as the retractable film of shape memory polymers and the self-heating layer of moisture-absorbing and heat-generating materials, ensures the reuse and high-efficiency performance of the materials. The substrate layer and the moisture-proof balance layer ensure the stability and moisture-proof performance of the structure. The composite molding and reserved groove setting by hot pressing gluing or riveting simplify the processing process and ensure that the layers of materials are tightly combined.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0020] Embodiment 1:

[0021] See also Figure 1-3 A composite board multilayer structure includes a wear-resistant layer 1, a water-absorbing layer 2 is fixedly connected to the lower end of the wear-resistant layer 1, a self-heating layer 3 is fixedly connected to the lower end of the water-absorbing layer 2, a substrate layer 4 is fixedly connected to the lower end of the self-heating layer 3, and a balancing layer 5 is fixedly connected to the lower end of the substrate layer 4. Water contacts the wear-resistant layer 1 and penetrates into the water-absorbing layer 2 to absorb the water and contact the self-heating layer 3, so that the self-heating layer 3 releases heat to dry the moisture after contacting the water, so that the water on the surface of the wear-resistant layer 1 dries quickly.

[0022] The wear-resistant layer 1 is formed by gluing or riveting two thinner solid wood boards. The outermost solid wood board can be coated with a wear-resistant coating to improve the wear resistance, which not only improves the overall strength and wear resistance of the wear-resistant layer, but also facilitates the subsequent arrangement of the swelling block 6. In particular, the water-absorbing fibers 64 can be arranged between the two solid wood boards to absorb and transmit the infiltrated moisture. At the same time, since the moisture is absorbed and is not easy to continue to penetrate into the inner solid wood board, the anti-seepage effect can be significantly improved, and the water-absorbing fibers 64 that form a mesh structure with each other can also expand the range and effect of water absorption.

[0023] The multi-layer composite board can not only accelerate the absorption and drying of ground moisture, keep the surface dry, but also improve the safety and comfort of the use environment.

[0024] The upper end of the wear-resistant layer 1 is provided with a plurality of evenly distributed grooves, in which swelling blocks 6 are fixedly connected. The swelling blocks 6 bulge when contacting water, so that the surface of the wear-resistant layer 1 with water presents a plurality of convex points, thereby playing an anti-slip role.

[0025] The swelling blocks 6 bulge automatically after contacting water, thereby significantly enhancing the anti-skid performance of the multi-layer structure of the composite board in a wet and slippery environment, effectively preventing the occurrence of slipping accidents, and improving the safety and applicability of the composite board.

[0026] The swelling block 6 includes swelling particles 61, which are embedded in the inner end of the groove, and the upper end of the swelling particles 61 is fixedly connected to a moisture sensing sheet 62, and the upper inner wall of the groove is fixedly connected to a retractable film 63, and the retractable film 63 is located at the upper end of the moisture sensing sheet 62, and the outer end of the moisture sensing sheet 62 is fixedly connected to a water-absorbing fiber 64, and the water-absorbing fiber 64 penetrates the wear-resistant layer 1. Through the arrangement of the retractable film 63 and the swelling particles 61, the swelling block 6 can drain moisture to the moisture sensing sheet 62 through the water-absorbing fiber 64 when it encounters water, so that it changes color and the swelling particles expand rapidly. The expanded particles 61 are made of shape memory polymer material. Shape memory polymer is a kind of intelligent material with memory effect. It can change its shape after being damp and return to its original shape after being dried. It can be reused. The retractable film 63 is made of elastic material. It deforms after being squeezed and is not only wear-resistant but also tear-resistant. Polyurethane, thermoplastic polyurethane, polyethylene terephthalate, polyamide, and polyethylene can be selected.

[0027] The retractable film 63 is a transparent elastic waterproof breathable film, and may be made of a TPU waterproof breathable film, which not only has excellent waterproof performance, but is also effectively breathable, allowing water vapor to pass through, thereby keeping the internal environment dry and comfortable, and has excellent strength and elasticity.

[0028] Through the combination of shape memory polymer and elastic material, the swelling block can expand rapidly when encountering water and return to its original shape after drying, ensuring the repeated use and durability of the anti-slip function. At the same time, the wear resistance and tear resistance of the material improve the durability of the composite board. The humidity sensing sheet 62 is made of humidity sensitive material. The temperature sensitive material changes color when encountering water due to temperature changes or solubility changes caused by moisture, and the color is restored after drying. Copper chloride and hydrated copper sulfate can be used.

[0029] The moisture-sensitive material changes color quickly when it comes into contact with water, providing obvious visual cues, effectively reminding users that the ground is slippery, preventing accidental slips, and improving the functionality and safety of the multi-layer structure of the composite board.

[0030] The water-absorbing layer 2 is made of a highly absorbent polymer material, which has a very high water absorption capacity and can absorb and retain a large amount of liquid. Polyvinyl alcohol and polyvinyl pyrrolidone can be selected, which can continue to be used after drying. The highly absorbent polymer material can quickly absorb a large amount of water and keep the surface dry, ensuring the efficient water absorption and repeated use performance of the multi-layer structure of the composite board, and extending the service life of the product.

[0031] The self-heating layer 3 is made of hygroscopic and heat-generating material, which dries the moisture on the surface of the composite board by releasing heat when in contact with water. At the same time, the self-heating layer 3 can continue to be used after drying. Calcium oxide, anhydrous calcium sulfate, and anhydrous calcium chloride can be selected, and they can be restored and recycled after heating.

[0032] The hygroscopic and heat-generating material releases heat while absorbing moisture, accelerating moisture evaporation and keeping the ground dry. The recyclable nature of the material further improves the utilization efficiency and environmental performance of the composite board multi-layer structure.

[0033] The substrate layer 4 is made of high-density fiberboard, and the balancing layer 5 is made of moisture-proof material, such as glass fiber reinforced plastic, carbon fiber composite material, phenolic resin composite material, polyurethane composite material, and aluminum-plastic composite material. It can not only play a moisture-proof role, but also effectively prevent the deformation of the board.

[0034] The high-density fiberboard provides excellent structural strength and stability, and the moisture-proof material ensures the durability and anti-deformation performance of the composite board in a humid environment, which improves the structural reliability and service life of the composite board as a whole.

[0035] See also Figure 4 , a method for processing a composite plate multilayer structure, comprising the following steps: S1. Select appropriate high-density fiberboard, carry out moisture-proof treatment, cutting and processing; S2, compositely forming the wear-resistant layer 1, the water-absorbing layer 2, the self-heating layer 3, the base material layer 4 and the balancing layer 5 by hot pressing, gluing or riveting; S3, embossing and polishing the surface of the wear-resistant layer 1, and chiseling out a plurality of evenly distributed grooves; S4, embed the swelling block 6 into the groove, and then seal the groove; S5. Finally, the composite board is grooved and chamfered, and the quality of the finished composite board is inspected; The high-density fiberboard is treated with moisture-proof treatment to ensure the durability and moisture resistance of the base material. The layers are firmly combined through a composite molding process such as hot pressing, gluing or riveting to ensure the overall strength of the composite board. The wear-resistant layer is embossed and polished, and swelling blocks made of shape memory polymer are embedded in the surface grooves to significantly enhance the anti-slip performance. The final grooving and chamfering treatment improves the safety and aesthetics of the product, ensuring the high performance, long life and applicability of the composite board as a whole.

[0036] The processing method of the swelling block 6 in step S4 comprises the following steps: S401, forming the upper end surface of the expanded particle 61 into an arc shape and embedding it into the groove; S402, using waterproof glue to fix the moisture sensing sheet 62 on the upper end of the expansion particle 61; S403, a placement groove is drilled on the inner wall of the groove, the water-absorbing fiber 64 is filled in, and then bonded to the moisture-sensitive sheet 62; S404, finally, the groove opening is sealed by retracting the film 63.

[0037] It can be seen from the above technical solutions that the present invention has the following beneficial effects: In this solution, the swelling blocks 6 fixed in multiple evenly distributed grooves on the wear-resistant layer 1 form raised particles when they come into contact with water, which significantly improves the anti-slip performance and ensures the safety of users in slippery environments. The color-changing function of the moisture-sensing sheet 62 can quickly remind the user that there is water on the ground to prevent accidental slips. The efficient water-absorbing layer 2 and the self-heating layer 3 can quickly absorb water and accelerate drying to keep the ground dry. The wear-resistant layer 1 and the retractable film 63 are made of wear-resistant and tear-resistant materials to ensure durability for long-term use. The application of smart materials, such as the expanded particles 61 of shape memory polymers, ensures the reuse and high-efficiency performance of the materials. The substrate layer 4 and the moisture-proof balance layer 5 ensure the stability and moisture-proof performance of the structure. The composite molding and reserved groove setting by hot pressing, gluing or riveting simplify the processing process and ensure that the layers of materials are tightly combined.
