The method is claimed to be simple in process, low in cost, and can regulate the structure, density, and mechanical strength of the honeycomb ceramics, and can also obtain materials with excellent performance and micro-nanoscale pores.

In the context of resource constraints and increased environmental protection requirements, it increases dependence on renewable resources, increases production energy consumption and environmental pollution, thereby reducing sustainability; secondly, there may be limitations in performance improvement. For example, the performance improvement may be relatively single, and may only focus on certain aspects of structure, density and mechanical strength, while key indicators such as high temperature resistance and impact resistance may not be prominent enough, reducing the reliability and service life of the material.

DETAILED DESCRIPTION

[0018] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0019] The embodiment of the present invention provides an impact-resistant honeycomb ceramic material including the following raw materials: The amount of the ceramic main material accounts for 65%-85% of the total weight, and the ceramic main material is one of silicon nitride ceramic powder, silicon carbide ceramic powder and zirconium oxide ceramic powder; The amount of bamboo fiber accounts for 6%-16% of the total weight. Bamboo fiber has high strength and toughness. Adding it to honeycomb ceramic materials can improve the strength and impact resistance of the materials, making the ceramic materials more stable and reliable when subjected to external impact. Bamboo fiber can also increase the toughness of the materials. In addition, bamboo grows rapidly and is a renewable resource, which can achieve sustainable utilization of resources. In addition, bamboo absorbs carbon dioxide and releases oxygen during its growth process, which has a positive impact on the environment and reduces energy consumption and environmental pollution in the production process. The amount of ramie fiber used is 6%-16% of the total weight. Ramie fiber has high strength and toughness. Adding it to ceramic materials can effectively improve the impact resistance of ceramic materials. When subjected to external impact, ramie fiber can absorb and disperse the impact force, reducing the risk of ceramic materials breaking. In addition, ramie is a natural plant that grows rapidly and is renewable, reducing dependence on non-renewable resources.

[0020] In order to further improve the performance of honeycomb ceramic materials, at the same time, promote the efficient use of bamboo resources, reduce dependence on traditional materials, and reduce the impact on the environment, therefore, according to Figure 2 As shown, the bamboo fiber extraction technology includes the following steps: Step 1: Raw material preparation: Select mature bamboo with good growth and no pests and diseases. The fiber quality of mature bamboo is higher. Cut the selected bamboo into 30-40cm length segments for subsequent processing; Step 2: Remove impurities: Rinse the bamboo segments with clean water, use a soft brush to gently scrub the surface of the bamboo to remove surface impurities, ensure that it is clean, and the cleaning time is not less than 10 minutes to ensure the cleaning effect. Then soak the cleaned bamboo segments in clean water for 40 minutes to further remove deep fine impurities and allow the bamboo to fully absorb water to prepare for the subsequent steaming process. After that, use a peeling tool to remove the skin of the cleaned bamboo. The skin usually contains more impurities and colors. After removal, the purity of the bamboo fiber is improved, and burrs are avoided to avoid affecting the quality of subsequent fiber extraction. Use a knife to flatten the bamboo nodes in the bamboo segment to make the fibers inside the bamboo more continuous and uniform. Step 3, cooking treatment: according to the solution concentration of 6%-10%, weigh the sodium hydroxide solid, slowly add it into the water and stir. The stirring speed should not be too fast to prevent the solution from splashing. At the same time, pay attention to the temperature change of the solution to avoid excessive temperature due to dissolution heat. After it is completely dissolved, cool it to room temperature and dilute it to the required volume with distilled water to ensure the concentration is accurate. Then, put the bamboo segment after removing impurities into the cooking container, add the cooking solution, make sure that the bamboo is completely immersed in the solution, ensure that the solution is sufficient, and then heat the container at 5℃ / Slowly heat up to the cooking temperature of 100-120℃ at a heating rate of 10-10℃ / min to avoid adverse effects of rapid temperature changes on bamboo and solution. Start timing the cooking for 2h-4h. During this period, a thermometer can be used to regularly monitor the solution temperature to ensure that it is stable within the set range. To ensure that the bamboo is in full contact with the cooking solution, use a high-temperature resistant glass rod to gently stir the bamboo segment for 1-2min every 30min to avoid excessive force that may damage the bamboo, so as to ensure full contact without affecting the stability of the cooking process. Step 4: Fiber extraction: After cooking, place the cooking container in a well-ventilated place to cool naturally for 1-2 hours. Avoid rapid cooling with cold water to prevent the bamboo and fiber from being damaged by sudden temperature changes. After cooling, remove the bamboo segments from the cooking solution and rinse them with running water to ensure uniform water flow. The rinsing time is not less than 15 minutes, until the water is clear and not turbid, so as to completely remove the cooking solution and impurities remaining on the bamboo surface. Then put the rinsed bamboo segments into the crusher one by one, or use a small pulping machine. Start the crusher for fiber separation. Adjust the speed to 500-1000 revolutions per minute according to the hardness and fiber characteristics of the bamboo. The pressure is moderate to avoid excessive damage to the fiber. The separated fibers are sieved. The bamboo fibers are screened with a sieve with a mesh size of 1mm-2mm to remove bamboo pieces and impurities. The bamboo pieces that do not meet the requirements are separated again to improve the fiber purity and yield. The bamboo fibers are screened with a sieve with a mesh size of 0.5mm-1mm to remove short fibers, fine impurities and dust. The screened fibers are soaked in clean water, and surfactants such as washing powder or dishwashing liquid are added. Detergent can also be added. Soak for 30-60 minutes. Stir gently to allow the detergent to fully contact the fibers to remove residual impurities and oil stains. After soaking, rinse repeatedly with clean water until the water is clear and foam-free. Take out the fibers and drain the water. Step 5, Drying and storage: Spread the extracted bamboo fiber evenly on the drying rack, ensure that there is enough space between the fibers for air circulation, place it in a well-ventilated and dry environment to dry naturally, turn the bamboo fiber every 2-3 hours to ensure uniform drying, and you can also use professional equipment such as hot air drying oven. If you use a hot air drying oven, set the temperature to 60℃-80℃, and turn the fiber every 1-2 hours to ensure uniform drying. The drying time depends on the moisture content of the fiber. Then put the dried bamboo fiber into a storage container and store it in a dry, ventilated place without direct sunlight. The storage container uses a sealed bag, a plastic barrel, and a special fiber storage container. Add a desiccant to keep it dry. The desiccant is preferably silica gel or quicklime. Seal the storage container to prevent the fiber from being damp, contaminated, and infested by insects. In addition, check the stored bamboo fiber every 4-5 weeks. Once moisture, deterioration, or signs of insect infestation are found, take timely measures such as re-drying, disinfection, or replacement of the storage container.

[0021] In order to further improve the impact resistance of ceramic materials, natural and environmentally friendly components with high strength and toughness are used to strengthen the prepared materials. Therefore, according to Figure 3 As shown, the ramie fiber extraction technology includes the following steps: Step 1: Raw material preparation: Select mature ramie plants that are well-grown and free of pests and diseases. The fiber quality is relatively good. Use a lawn mower to harvest the ramie plants. You can also use a sickle to harvest. Keep a length of 30-50cm for subsequent processing. Step 2, remove impurities: put the harvested ramie into clean water, brush it gently with a brush to remove the dirt, dust and other impurities on the surface, wash it repeatedly 4-6 times to ensure that the ramie is clean, soak the washed ramie in water for 16-24 hours to soften the impurities such as pectin in the ramie, which is convenient for subsequent processing, then take the soaked ramie out of the water, remove the ramie skin with a peeling machine, or use a peeling knife to peel. The skin contains more impurities and lignin. Removing the skin can improve the purity of the fiber. Then, gently tap the peeled ramie with a hammer to separate the xylem from the fiber. The xylem contains more lignin and cellulose. Removing the xylem can improve the flexibility and strength of the fiber. Step 3, fiber extraction: put the ramie with the wood removed into a cooking pot, add water and sodium hydroxide cooking agent, and cook at a cooking temperature of 100-120°C for 2-4 hours to further soften and decompose the impurities such as pectin in the ramie, so as to facilitate the extraction of the fiber. Then take the cooked ramie out of the cooking pot, put it into clean water for rinsing, remove the cooking agent and impurities in the ramie, and make the fiber softer and smoother. The number of rinsing is 3-5 times. After that, put the rinsed ramie into a beating machine for beating to separate the fibers in the ramie and remove the impurities and short fibers in the fibers. The number of beating is 2-3 times. Then put the beaten ramie fibers into a carding machine for carding to make the fibers more neat and uniform and remove the impurities and short fibers in the fibers. The number of carding is 2-3 times. Step 4: Drying and storage: Put the combed ramie fiber into a dryer for drying at a temperature of 60-80°C for 2-4 hours to evaporate the moisture in the fiber and improve the strength and stability of the fiber. Put the dried ramie fiber into a sealed bag or a sealed container and store it in a dry and ventilated place, avoiding direct sunlight and a humid environment to avoid affecting the quality of the fiber.

[0022] In the present invention, firstly, the addition of bamboo fiber and ramie fiber can not only provide the basic structure and performance basis by using the ceramic main material, but also enhance the overall strength and high temperature resistance of the material. At the same time, it is also conducive to subsequent processing and molding. For example, one of silicon nitride ceramic powder, silicon carbide ceramic powder and zirconium oxide ceramic powder is selected as the ceramic main material, which has outstanding performance in strength, hardness, high temperature resistance, impact resistance and the like, and can complement each other to improve the comprehensive performance of the ceramic material, and can also effectively improve the impact resistance of the honeycomb ceramic material. Moreover, the secondary combination of ramie fiber and bamboo fiber can further enhance the impact resistance and toughness of the material. The two work together to form a complex fiber network structure in the ceramic material. When the material is impacted by external force, the fiber can absorb and disperse the impact force, thereby reducing the risk of rupture of the ceramic material. The secondary bonding reaction of ramie fiber and bamboo fiber includes physical bonding and chemical action: In terms of physical bonding, the fibers are interwoven to form a complex three-dimensional network structure, which can build a stable support system in the ceramic material. At the same time, through mixing, the fibers are embedded in each other, which enhances the tightness of the connection. In addition, the van der Waals force also plays a role between the fibers, further increasing the bonding force between the fibers, so that the fibers can be more firmly combined in the ceramic material, jointly bear the external force, and improve the overall stability and mechanical properties of the material. In terms of chemical action, the cellulose molecules in the fiber can form important hydrogen bonds. Specifically, the hydroxyl group in the cellulose molecule has a strong polarity, and it can form hydrogen bonds with the hydroxyl group in the adjacent cellulose molecules through electrostatic attraction. The formation of this hydrogen bond enhances the binding force between the fibers, allowing the fibers to be more closely combined in the ceramic material. The presence of hydrogen bonds not only helps to improve the stability of the fibers, but also can better transfer stress when the material is subjected to external forces, thereby enhancing the overall mechanical properties of the material. In addition, the formation of hydrogen bonds also affects other properties of the material, such as water absorption and thermal stability.

[0023] The use of bamboo fiber and ramie fiber improves the environmental sustainability of the building material. Bamboo grows rapidly and is a renewable resource. Ramie is also a natural plant that grows rapidly and is renewable. The use of these fibers not only reduces dependence on non-renewable resources, but also reduces energy consumption and environmental pollution in the production process. During the preparation process, bamboo fiber and ramie fiber are extracted and processed to make full use of natural resources and realize resource utilization. At the same time, during the production process, the control of temperature changes and the use of the reaction between fiber and ceramic main material improve the performance of the material while reducing the adverse impact on the environment, thereby improving the green environmental value and sustainable development of the building material.

[0024] according to Figure 1As shown, the embodiment of the present invention also provides a method for preparing the above-mentioned impact-resistant honeycomb ceramic material, and the specific steps are as follows: (1) Raw material preparation: ceramic main material, bamboo fiber and ramie fiber; (2) Mixing raw materials: Mix the ceramic main material powder, bamboo fiber and ramie fiber, and use a mechanical stirring method to ensure uniform mixing so that the bamboo fiber and ramie fiber are evenly distributed in the ceramic powder; (3) Preparation of honeycomb structure: The mixed raw materials are prepared into a honeycomb structure by injection molding or extrusion molding. A binder and a lubricant are added during the molding process. The amount of the binder is 1%-4%, and the amount of the lubricant is 0.5%-2% to improve the molding quality and efficiency and ensure that the pores of the honeycomb structure are uniform and of appropriate size. (4) Sintering treatment: The formed honeycomb ceramic material is sintered at a sintering temperature of 1400℃-2300℃; when the ceramic main material is silicon nitride ceramic powder, the sintering temperature is 1700℃-1900℃; when the ceramic main material is silicon carbide ceramic powder, the sintering temperature is 2000℃-2300℃; when the ceramic main material is zirconium oxide ceramic powder, the sintering temperature is 1400℃-1700℃; the specific sintering time is adjusted according to the thickness and performance requirements of the material. During the sintering process, the heating rate and cooling rate are controlled. The heating rate is controlled at 2℃ / min-8℃ / min, and the cooling rate is controlled at 1℃ / min-6℃ / min to avoid material cracking or performance degradation due to rapid temperature changes. At the same time, bamboo fiber and ramie fiber will react with the ceramic main material at high temperature to form a good bond, thereby improving the strength and impact resistance of the material. (5) Post-processing: The sintered honeycomb ceramic material is processed, for example, grinding and polishing to improve the surface quality and dimensional accuracy, and then performance tests are carried out, such as impact strength test, hardness test, porosity test, etc., to ensure that the material meets the requirements. If the performance does not meet the standards, the raw material ratio, molding process or sintering parameters can be adjusted and re-prepared.

[0025] In the present invention, when the sintering temperature rises, the ceramic main material powder begins to undergo physical and chemical changes, the atomic diffusion between the ceramic particles intensifies, the pores between the particles gradually decrease, and the material gradually densifies. At the same time, the high temperature also promotes the decomposition of the organic components in the bamboo fiber and the ramie fiber, leaving a fiber skeleton with strength and toughness; at high temperature, the bamboo fiber and the ramie fiber will react with the ceramic main material. On the one hand, the organic components such as cellulose in the fiber will chemically react with the oxide in the ceramic main material to form a chemical bond, thereby enhancing the bonding force between the fiber and the ceramic; on the other hand, the fiber will undergo physical changes such as carbonization at high temperature to form a fiber skeleton with certain strength and toughness, which together with the ceramic main material constitutes a composite material; In addition, by controlling the heating rate, a slow heating rate of 2℃ / min-8℃ / min is required. This can prevent the material from generating thermal stress due to rapid temperature changes, which can cause material cracking or performance degradation. During the heating process, the temperature inside the material gradually and evenly increases, the diffusion and reaction between the ceramic particles can proceed smoothly, and the bond between the fiber and the ceramic main material is also stronger. Similarly, a slow cooling rate of 1℃ / min-6℃ / min can prevent the material from generating residual stress due to excessive cooling, which can affect the material's performance and stability. During the cooling process, the internal structure of the material gradually stabilizes, and the bond between the fiber and the ceramic main material is also closer.

[0026] In terms of preparation methods, from raw material preparation to mixing, molding, sintering and then to post-processing, mechanical stirring improves the uniform distribution of fibers in ceramic powder, the injection molding method can efficiently prepare honeycomb structures, the addition of binders and lubricants improves molding quality and efficiency, and the precise control of temperature and heating and cooling rates during sintering improves the material's stable performance and avoids cracking and other problems. The post-processing steps further improve the material's surface quality and dimensional accuracy, thereby enhancing the overall quality and market competitiveness of the product.
