Description

Technical Field

[0001] The invention belongs to the field of building technology, in particular to a low-carbon footprint bio-based material composite insulation board. Background Art

[0002] Low-carbon footprint bio-based composite insulation board is an insulation material designed to reduce carbon emissions, improve energy efficiency and promote sustainable development. Low-carbon footprint bio-based composite insulation board combines a variety of environmentally friendly materials and technologies, and achieves lower carbon emissions and higher energy efficiency through optimized design and production processes.

[0003] Although low-carbon footprint bio-based composite insulation boards have made certain progress in technology and application, their technical maturity still needs to be improved. In particular, the stability, durability and adaptability of the materials still need further research and improvement. After the traditional low-carbon footprint bio-based composite insulation boards are installed, the orientation of the low-carbon footprint bio-based composite insulation boards cannot be adjusted, resulting in the inability to adjust the insulation angle.

[0004] In summary, the fact that the insulation angle of the existing low-carbon footprint bio-based composite insulation board cannot be adjusted after installation has become a problem that technicians in this field need to solve urgently. Therefore, it is necessary to propose a low-carbon footprint bio-based composite insulation board. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to propose a low-carbon footprint bio-based composite insulation board; by optimizing the board structure design and production process, and then cooperating with a rotating box to mechanically rotate the angle of each board, the insulation angle can be adjusted according to actual needs after the board is installed.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a low-carbon footprint bio-based material composite insulation board, comprising a hollow plate and a bio-based material, a plurality of rotating components for adjusting the angle of the plate are hinged on one side of the bottom of the outer wall of the plate, the bio-based material is filled in the plate to form a bio-based material layer, a fireproof layer and a waterproof layer are sequentially embedded on the side of the bio-based material layer away from the rotating component, the fireproof layer and the waterproof layer divide the bio-based material layer into a three-layer structure, a plurality of nano-carbon tubes are embedded in each bio-based material layer along the length direction, the outer walls of the nano-carbon tubes are sprayed with graphene, and the outer walls of the graphene are sprayed with nano-oxides.

[0007] The following principles and beneficial effects are achieved by adopting the above scheme:

[0008] Basic principle: The bio-based material layer is the main filler of the board. It is not only environmentally friendly and renewable, but also has certain insulation and mechanical strength. Several carbon nanotubes are embedded in the bio-based material. The high strength and conductivity of the carbon nanotubes are used to enhance the mechanical properties and thermal stability of the entire insulation board. The fireproof layer uses inorganic fiber materials treated with flame retardants, which can maintain structural stability at high temperatures and prevent the spread of fire; the waterproof layer uses polymer waterproof coatings to effectively prevent water penetration and protect the internal materials from erosion. The rotating box is hinged on the bottom side of the outer wall of the board, so that each board can be adjusted according to actual needs after installation.

[0009] Beneficial effects:

[0010] 1. The present invention uses bio-based materials as the main filler, which reduces dependence on fossil resources, reduces carbon emissions, and conforms to the concept of low-carbon environmental protection. Bio-based materials are easy to process and have good maintainability, reducing production and maintenance costs. The low-carbon environmental protection principle is taken into consideration in both design and material selection. Its excellent thermal insulation performance helps to reduce energy consumption inside the building, thereby further reducing carbon emissions.

[0011] 2. The present invention significantly improves the insulation performance of the insulation board through a multi-level, multi-material composite design, especially the application of carbon nanotubes, graphene and nano oxides, and is suitable for various occasions requiring good insulation effects. Through the designed multi-level structure, an efficient insulation barrier is formed. Graphene and carbon nanotubes serve as guide channels, and through their unique arrangement, they effectively guide and disperse current and heat, avoiding vertical penetration, thereby significantly improving the insulation effect. The addition of graphene uses its excellent electrical and thermal conductivity to further enhance the insulation board's ability to control current and heat.

[0012] 3. The present invention forms a unique double protection structure by setting up a fireproof layer and a waterproof layer, providing double protection for the insulation board. The fireproof layer is made of high temperature resistant and non-flammable materials, which can maintain structural stability in a high temperature environment, effectively prevent the spread of fire, and ensure the safety of the insulation board and the surrounding environment. At the same time, the waterproof layer uses a polymer waterproof coating or other high-performance waterproof materials to form a dense waterproof barrier, effectively blocking water penetration and preventing internal materials from getting damp and corroded, thereby extending the service life of the insulation board and enhancing the safety and durability of the insulation board.

[0013] 4. The reinforcing effect of the carbon nanotubes in the present invention makes the insulating board have higher mechanical strength and can withstand certain external forces without being easily damaged. In the insulating board, the carbon nanotubes form a strong reinforcing network through a carefully designed arrangement, which effectively improves the overall strength and rigidity of the board. This reinforcing effect enables the insulating board to show higher compression, bending and impact resistance when facing external forces, and is not easy to be damaged or deformed.

[0014] 5. The design of the rotating assembly in the present invention adds additional functionality and flexibility to the insulation board, which can be installed and adjusted according to specific needs. After installation, the insulation board can be adjusted in angle according to environmental changes and actual needs. This intelligent adaptability enables the insulation board to more effectively respond to the insulation needs in different seasons and different climatic conditions, thereby improving energy efficiency and reducing energy consumption.

[0015] Furthermore, the production process of low carbon footprint bio-based composite insulation board comprises the following steps:

[0016] Step 1, material selection: the board includes the following parts by weight: 8 to 9 parts of bio-based materials, including bamboo fiber, flax fiber and lignin; 1 to 2 parts of barrier materials, including carbon nanotubes, graphene, nano oxides, fireproof layer materials and waterproof layer materials;

[0017] Step 2, polymerization and molding: embedding carbon nanotubes in the bio-based material, spraying a graphene layer on the outer wall of the carbon nanotubes, spraying nano oxides on the outer wall of the graphene layer, and then polymerizing the fireproof layer and the waterproof layer embedded in the bio-based material;

[0018] The polymerized material is poured into a designed mold and formed into a sheet by pressing;

[0019] Step 3: Curing operation: placing the formed sheet into a curing furnace for heating and curing;

[0020] Step 4: Post-curing treatment: Take the cured board out of the curing furnace for natural cooling, and then package the board after natural cooling.

[0021] Beneficial effects: By choosing bio-based materials such as bamboo fiber, flax fiber and lignin as the main raw materials, the dependence on fossil resources is significantly reduced, carbon emissions are reduced, and the concept of low-carbon environmental protection and sustainable development is met. These bio-based materials are not only renewable, but also have good natural degradation, which helps to reduce environmental pollution.

[0022] Furthermore, in step one, the bio-based material is made of bamboo fiber, flax fiber and lignin in a mass ratio of 1:1:2.

[0023] Beneficial effects: Bamboo fiber, flax fiber and lignin each have unique physical and chemical properties. Bamboo fiber has high strength and excellent water resistance, flax fiber has good flexibility and air permeability, and lignin has strong bonding force. By mixing these three materials in a ratio of 1:1:2, their respective advantages can be fully utilized to form a synergistic effect, thereby improving the overall performance of the insulation board.

[0024] Furthermore, in step 2, the fireproof layer is made of inorganic fiber material treated with a flame retardant, and the waterproof layer is made of polyurethane environmentally friendly series waterproof coating.

[0025] Beneficial effects: The fireproof layer is made of inorganic fiber material treated with flame retardant, which can maintain structural stability at high temperatures, is not easy to burn, and can effectively prevent the spread of fire. The waterproof layer uses polyurethane environmentally friendly series waterproof coating, which has excellent waterproof performance and can effectively prevent water penetration.

[0026] Furthermore, during the heating and curing process, a pressure of 5MPa-10MPa is applied to the plate in the curing furnace.

[0027] Beneficial effects: Applying pressure to the board helps to make the bio-based materials, carbon nanotubes, graphene, nano-oxides and other components inside the board more tightly combined, reducing pores and defects, thereby increasing the density of the material.

[0028] Furthermore, in step three, the heating temperature in the curing furnace is 180° C. to 200° C., and the heating time is 2 hours.

[0029] Beneficial effect: The performance of the insulation board cured under this condition is more stable and can better adapt to the use requirements under various environmental conditions. Whether in high temperature or humid environment, the insulation board can maintain its excellent performance and provide reliable protection for various application scenarios.

[0030] Furthermore, in step three, ultrasonic vibration treatment is introduced into the plate after the heating and curing treatment is completed.

[0031] Beneficial effects: The introduction of ultrasonic treatment process further promotes the close bonding of the various layers of materials inside the board through ultrasonic vibration, while helping to release internal stress and improve the overall uniformity and stability of the board. Ultrasonic treatment can also effectively remove residual gas and impurities on the surface and internal tiny pores of the board, improving the purity and insulation performance of the board.

[0032] Furthermore, in step 4, the ambient temperature during the natural cooling process is 20° C. to 25° C., and the humidity is 40% to 50%.

[0033] Beneficial effects: The board absorbs a lot of heat during the heating and curing process. If it is cooled quickly, it may produce thermal stress due to excessive temperature gradient, causing deformation or cracking of the board. Natural cooling under suitable ambient temperature and humidity conditions can slowly release the heat inside the board, reduce the generation of thermal stress, and thus protect the integrity and performance of the board.

[0034] Furthermore, the rotating assembly includes a rotating box, a transmission block is provided in the rotating box, a first transmission rod and a second transmission rod are hinged on the inner wall of the rotating box respectively, the other ends of the first transmission rod and the second transmission rod are hinged to the transmission block, and the transmission block is fixedly connected to the outer wall of the plate.

[0035] Beneficial effects: The structural design of the transmission block and transmission rod enables the board to maintain high precision during installation. By precisely controlling the length and angle of the transmission rod, it can be ensured that the board will not deviate or twist during installation, thereby ensuring the stable performance of its heat insulation, fireproof and waterproof properties.

[0036] Furthermore, a spring is provided between the first transmission rod and the second transmission rod, one end of the spring is fixedly connected to the inner wall of the rotating box, and the other end of the spring is fixedly connected to the transmission block.

[0037] Beneficial effect: The elastic force of the spring can assist the movement of the first transmission rod and the second movement rod, making the transmission process smoother and more efficient. When the angle of the plate needs to be adjusted, the plate is subjected to external force, and the angle adjustment can be more easily achieved through the coordinated action of the transmission block, the transmission rod and the spring, reducing the resistance and energy loss in the transmission process.

DETAILED DESCRIPTION

[0044] The following is further described in detail through specific implementation methods:

[0045] Example 1

[0046] Basically as attached Figure 3 As shown: The production process of low carbon footprint bio-based composite insulation board includes the following steps:

[0047] Step 1, material selection: the board 1 includes the following parts by mass: 9 parts of bio-based material layer 5, the bio-based material layer 5 is made of bamboo fiber, flax fiber and lignin in a mass ratio of 1:1:2, 1 part of barrier material, the barrier material is selected from nano carbon tubes 8, graphene 6, nano oxide 7, a fireproof layer 3 and a waterproof layer 4.

[0048] Bamboo fiber, flax fiber and lignin are selected as the main components of the bio-based material layer 5. These materials are all derived from renewable resources, meet environmental protection standards, reduce dependence on fossil resources, and achieve low carbon emissions. At the same time, these materials are biodegradable after the end of their life cycle, reducing the environmental burden.

[0049] Step 2, polymerization and molding: embed carbon nanotubes 8 into the bio-based material layer 5, spray a layer of graphene 6 on the outer wall of the carbon nanotubes 8, spray nano oxides 7 on the outer wall of the graphene 6, and then embed the fireproof layer 3 and the waterproof layer 4 for polymerization. The fireproof layer 3 adopts inorganic fiber material treated with flame retardant, and the waterproof layer 4 adopts polyurethane environmentally friendly series waterproof coating; pour the polymerized material into the designed mold and form the board 1 by pressing.

[0050] By nesting the layers one by one, a stable three-layer structure is formed, which not only enhances the fireproofing, waterproofing and insulation performance of the board 1, but also improves the overall structural strength and durability.

[0051] Step 3, curing operation: put the formed sheet 1 into the curing furnace for heating and curing. During the heating and curing process, a pressure of 10MPa is applied to the sheet 1 in the curing furnace. The heating temperature in the curing furnace is 180°C and the heating time is 2 hours. During the heating process, the temperature in the furnace must be kept uniform to avoid local overheating and material performance degradation. After the heating and curing process, ultrasonic vibration treatment is introduced to the sheet to further promote the close bonding of the various layers of materials inside the sheet, and at the same time help release internal stress and improve the overall uniformity and stability of the sheet.

[0052] Applying pressure during the heating and curing process helps the components inside the material to be tightly combined and densified, thereby improving the mechanical properties and dimensional stability of the plate 1. At the same time, the high temperature curing process promotes the completion of the internal reaction of the material, further improving the performance of the plate 1.

[0053] Step 4, post-curing treatment: the cured plate 1 is taken out from the curing furnace for natural cooling treatment. The ambient temperature during the natural cooling treatment is 20° C. and the humidity is 40%. After the natural cooling treatment, the plate is packaged.

[0054] The natural cooling process under suitable ambient temperature and humidity conditions helps to reduce the thermal stress of the plate 1 caused by rapid cooling, thereby preventing the plate 1 from deforming or cracking.

[0055] The specific implementation process is as follows:

[0056] High-quality bamboo fiber, flax fiber and lignin are selected as raw materials in a mass ratio of 1:1:2. First, the three fibers are washed and dried separately to remove impurities and moisture. Then, the treated fibers are mixed evenly and mechanically stirred and air flow crushed to achieve a preset particle size distribution for subsequent processing.

[0057] Nano carbon tubes 8, graphene 6, and nano oxides 7 are selected as reinforcing materials. At the same time, inorganic fiber materials treated with flame retardants are prepared as fireproof layers 3, and polyurethane environmentally friendly series waterproof coatings are prepared as waterproof layers 4. These barrier materials ensure that while enhancing performance, they can also meet various functional requirements.

[0058] Then, carbon nanotubes 8 are uniformly embedded in the bio-based material layer 5 to ensure that the carbon nanotubes 8 are evenly distributed in the bio-based material layer 5. Then, a layer of graphene 6 is sprayed on the outer wall of the carbon nanotubes 8 to form a conductive and enhanced intermediate layer. Next, a layer of nano oxide 7 is sprayed on the graphene 6 layer to improve the corrosion resistance and stability of the material.

[0059] Then embed the fireproof layer 3 and the waterproof layer 4. The fireproof layer 3 is made of inorganic fiber material treated with flame retardant, which can effectively prevent the spread of flames. The flame retardant treatment means that the inorganic fiber material is completely immersed in the flame retardant solution, so that the flame retardant fully penetrates into the fiber. Then use the coating equipment to evenly coat the flame retardant solution on the surface of the inorganic fiber material to form a flame retardant film. Through chemical reaction, the flame retardant and the inorganic fiber material are covalently bonded to achieve a stronger flame retardant effect; the waterproof layer 4 uses polyurethane environmentally friendly series waterproof coating to ensure that the board has good waterproof performance.

[0060] The constructed material is poured into a pre-designed mold, and the preset shape and size of the plate 1 is formed through pressing and injection molding processes. The formed plate 1 is then placed in a curing furnace and heated and cured at a temperature of 180°C. At the same time, a pressure of 10MPa is applied to the plate to promote the close bonding and densification of the internal components of the material. The heating time is set to 2 hours, during which the temperature in the furnace must be kept uniform to avoid local overheating that may lead to a decrease in material performance.

[0061] After the heating and curing treatment is completed, ultrasonic vibration treatment is immediately introduced to the plate 1. Ultrasonic vibration can further promote the close bonding of the layers of materials inside the plate, while helping to release internal stress and improve the overall uniformity and stability of the plate 1.

[0062] The cured board 1 is taken out of the curing furnace and subjected to natural cooling treatment under the condition of an ambient temperature of 20° C. and a humidity of 40%. Natural cooling helps to reduce the thermal stress of the board caused by rapid cooling and prevents the board from deformation or cracking.

[0063] Finally, after the natural cooling process is completed, the plate 1 is visually inspected and cleaned to remove any impurities or burrs that may exist on the surface, and then the plate 1 is packaged for storage and transportation.

[0064] Example 2

[0065] Basically as attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: Different from the above-mentioned embodiments, the low-carbon footprint bio-based composite insulation board includes a hollow plate 1 and a bio-based material. A plurality of rotating components for adjusting the angle of the plate 1 are hinged on one side of the bottom of the outer wall of the plate 1. The bio-based material is filled in the plate 1 to form a bio-based material layer 5. A fireproof layer 3 and a waterproof layer 4 are sequentially embedded on the side of the bio-based material layer 5 away from the rotating component. The fireproof layer 3 and the waterproof layer 4 divide the bio-based material layer 5 into a three-layer structure. A plurality of nano-carbon tubes 8 are embedded in each bio-based material layer 5 along the length direction. Graphene 6 is sprayed on the outer wall of the nano-carbon tube 8, and nano-oxide 7 is sprayed on the outer wall of the graphene 6.

[0066] The rotating assembly includes a rotating box 2, a transmission block 11 is arranged in the rotating box 2, a first transmission rod 10 and a second transmission rod 12 are respectively hinged on the inner side wall of the rotating box 2, the other ends of the first transmission rod 10 and the second transmission rod 12 are hinged to the transmission block 11, and the transmission block 11 is fixedly connected to the outer wall of the plate 1 by bolts. A spring 9 is arranged between the first transmission rod 10 and the second transmission rod 12, one end of the spring 9 is fixedly connected to the inner side wall of the rotating box 2 by bolts, and the other end of the spring 9 is fixedly connected to the transmission block 11 by bolts.

[0067] The specific implementation process is as follows:

[0068] First, measure the size of the wall where the panels 1 are to be installed, and determine the number and layout of the panels 1. Plan the installation position and number of the rotating boxes 2 according to the wall structure and load-bearing capacity to ensure that the panels 1 can be firmly fixed to the wall through the rotating boxes 2.

[0069] The plate 1 is installed on a designated wall through a plurality of rotating boxes 2, and a cavity is formed between the plate 1 and the wall, and the cavity can also play a role in sound insulation.

[0070] When the environmental parameters change, the plate 1 receives the impact of heat and current from the outside world, and a part of the heat and current is first consumed to break through the plate 1 and reach the bio-based material layer 5. If the heat and current have not been consumed, the remaining heat and current will be attracted by the graphene 6 with conductivity and the carbon nanotubes 8 with thermal conductivity, and begin to transfer in the direction of graphene 6 and carbon nanotubes 8, inducing the heat and current to pass through the nano-oxide 7 and graphene 6 in turn to reach the carbon nanotubes 8, and the nano-oxide 7, graphene 6 and carbon nanotubes 8 further consume the heat and current; because the carbon nanotubes 8 are placed horizontally on the plate 1, the conduction direction of heat and current is changed, and the heat and current are prevented from penetrating the entire plate 1, achieving better thermal insulation and insulation effects.

[0071] At the same time, the fireproof layer 3 and the waterproof layer 4 also play a role in blocking heat and current. The fireproof layer 3 is mainly composed of high-temperature resistant and non-flammable materials, which can effectively prevent the spread of fire and protect the wall and internal structure from fire damage. The waterproof layer 4 uses high-density waterproof materials to ensure that moisture cannot penetrate into the board 1, thereby maintaining the dryness and stability of the building structure.

[0072] In the process of heat and current transfer, the fireproof layer 3 and the waterproof layer 4 not only act as physical barriers, but also further consume the remaining heat and current through their material properties. The high temperature stability of the fireproof layer 3 can absorb and disperse part of the heat, reducing its direct effect on the board 1 and the wall; while the waterproof layer 4 reduces the penetration of water due to its dense structure.

[0073] When the direction of the plate 1 needs to be changed, the user can use the limiting relationship between the first transmission rod 10 and the second transmission rod 12 in the rotating box 2 and the auxiliary pulling force of the spring 9 to pull the plate 1 at one end away from the rotating box 2. Since the rotating box 2 is fixedly connected to the wall, the first transmission rod 10 and the second transmission rod 12 rotate to move the transmission block 11 on the plate 1, thereby allowing the entire plate 1 to move in a preset direction. When it moves to the preset orientation, the plate 1 can be fixed by the auxiliary pulling force of the spring 9.

[0074] When the plate 1 needs to be reset, the plate 1 at one end away from the rotating box 2 is pressed, and the first transmission rod 10, the second transmission rod 12 and the spring 9 begin to reset to the initial position, and after reaching the initial position, the spring 9 fixes the entire transmission mechanism. This transmission method is mechanized and more labor-saving, reducing the burden on users.

[0075] The design of the rotating box 2 not only provides flexibility for the installation and adjustment of the plate 1, but also enhances the stability of the entire plate 1. When the external environment changes, the rotating box 2 can achieve a certain degree of adaptive adjustment through the interaction of the transmission block 11, the first transmission rod 10, the second transmission rod 12 and the spring 9 inside it, thereby reducing the stress impact on the plate 1 and protecting the integrity of the plate 1 and its internal structure.

[0076] Finally, the entire low-carbon footprint bio-based composite insulation board can not only effectively isolate the external heat, current, flame and moisture, but also has excellent sound insulation performance, creating a more comfortable, safe and energy-saving environment inside the building. At the same time, due to the use of bio-based material layer 5 and recyclable nanomaterials, the low-carbon footprint bio-based composite insulation board also plays a positive role in reducing carbon emissions and promoting resource recycling, which is in line with the concept of sustainable development.

[0077] The above is only an embodiment of the present invention. The common sense such as the known specific structure and characteristics in the scheme is not described in detail here. The ordinary technicians in the relevant field know all the common technical knowledge in the technical field of the invention before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date. The ordinary technicians in the relevant field can improve and implement this scheme in combination with their own abilities under the enlightenment given by this application. Some typical known structures or known methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
