Description

Technical Field

[0001] The invention relates to the technical field of waterproof boards, in particular to an antibacterial and anti-mildew waterproof board and a production process thereof. Background Art

[0002] The main function of waterproof board is waterproofing. It can effectively prevent water penetration. Whether it is rainwater, groundwater or other liquids, it is difficult to penetrate the waterproof board. This function makes it widely used in the basement, roof and exterior wall of the building. For example, in the basement, the waterproof board is like a barrier to prevent groundwater from seeping into the room; the waterproof board on the roof resists rainwater to avoid water leakage in the house. It also has an isolation function, which can separate water from the protected structure or object to prevent water from directly contacting the building materials, thereby reducing material damage, structural deformation and corrosion caused by water erosion. For example, in underground projects, it isolates groundwater and tunnel lining structures. Some waterproof boards have good chemical resistance and can resist the erosion of chemical substances. When in contact with some corrosive liquids, such as sewage and chemical reagents, they can still maintain good performance, maintain their own integrity and ensure waterproof effect. In addition, some waterproof boards also have a certain puncture resistance. During the construction process or in the use environment, even if they are punctured by external forces, such as being touched by construction tools or squeezed by sharp objects on the ground, they are not easy to break, so they can continue to play a waterproofing function.

[0003] The existing waterproof panels usually do not have a connection structure during use, and are not convenient for quick and stable assembly and disassembly during use;

[0004] The Chinese patent with the announcement number "CN219952276U" discloses a modular waterproof board that is easy to disassemble, which includes a first waterproof board, first limiting connectors are installed at both ends of the outer wall of the first waterproof board body, and the first limiting connector has a combination slot on both sides of the middle of the outer wall, and the second limiting connector is installed at both ends of the outer wall of the second waterproof board body. Insertion rods are installed at both sides of the middle of the outer wall of the second limiting connector, and the insertion rod can be inserted into the combination slot for positioning and connection. The positioning screws penetrate the first limiting connector and the second limiting connector and are positioned and connected with the first waterproof board body and the second limiting connector. The first limiting connector and the second limiting connector are positioned with the first waterproof board body and the second waterproof board body by the positioning screws. After positioning, the second limiting connector and the insertion rod on the second waterproof board body are inserted into the combination slot for positioning and connection. The device is a modular detachable structure with a simple structure and easy operation.

[0005] Although the above-mentioned waterproof board is easy to combine and install in overall design, and can be quickly assembled during use, which brings certain convenience to construction, the current waterproof board has obvious shortcomings. The waterproof board as a whole lacks an effective limiting structure and is only installed by simple mutual combination. After the combined installation, it is usually necessary to further fix it with bolts, etc., which makes the overall installation stability poor. In actual use, it is easy to loosen, shift, and other problems. At the same time, since the waterproof board is usually located in a humid environment and even immersed in water for a long time, in this case, the waterproof board is extremely susceptible to corrosion and deformation. After long-term use, the waterproof board is extremely easy to be damaged, which not only affects the waterproof effect, but also causes damage to related facilities. Therefore, in order to improve the performance and service life of the waterproof board, it is urgent to improve its design. Summary of the invention

[0015] Furthermore, the composite layer includes an inner layer, the inner side is arranged at the innermost side of the composite layer, the outer side of the inner layer is fixedly connected to the first middle layer, the outer side of the first middle layer is fixedly connected to the second middle layer, the outer side of the second middle layer is fixedly connected to the wear-resistant protective layer, and the outer side of the wear-resistant protective layer is fixedly connected to the weather-resistant antibacterial layer.

[0017] A production process of an antibacterial and anti-mildew waterproof board comprises the following steps:

[0018] Step 1: Prepare the inner layer material, prepare the antibacterial and mildew-proof polyvinyl chloride material, check whether its quality meets the standards, and ensure that it has good antibacterial and mildew-proof properties. The thickness of the polyvinyl chloride can be within the range of 0.5-1.5 mm;

[0019] Step 2: Inner layer production: antibacterial and mildew-proof polyvinyl chloride material is installed on the base layer by hot pressing, gluing, etc. The hot pressing temperature can be controlled at 120-150°C, the pressure at 2-4MPa, and the time at 10-20 minutes to form a flat and firm inner layer without defects such as bubbles and wrinkles;

[0020] Step 3: Prepare the first middle layer material, select aerogel materials of good quality, ensure that its thermal insulation, heat preservation and waterproof performance meet the standards, and the density of aerogel can be in the range of 5-20 kg / m3;

[0021] Step 4: Lay the first middle layer on the aerogel material on the antibacterial and mildew-proof polyvinyl chloride inner layer, and pay attention to ensure the flatness and close fit of the aerogel layer. The laying thickness can be within the range of 2-5 mm;

[0022] Step 5: Preparation of the second middle layer material, preparing titanium nanotubes and chitin fibers, ensuring that the titanium nanotubes have high strength, high toughness and good corrosion resistance, and the chitin fibers have natural antibacterial properties, the diameter of the titanium nanotubes can be in the range of 10-50 nanometers, and the length of the chitin fibers can be in the range of 1-5 millimeters;

[0023] Step 6: The second middle layer composite, when preparing titanium nanotubes and chitin fibers, they are strictly quality inspected to ensure that the diameter of the titanium nanotubes is in the range of 10-50 nanometers, with high strength, high toughness and good corrosion resistance, and the length of the chitin fibers is in the range of 1-5 mm, with natural antibacterial properties. Then, when the weaving process is used for composite, the density of the weaving should be precisely controlled to reach the range of 50-100 fibers per square centimeter. During the weaving process, it is necessary to ensure that the fibers are arranged neatly to avoid cross-over, entanglement and other undesirable conditions. At the same time, it is necessary to control the weaving speed and tension to ensure the stability and uniformity of the weaving structure. If the lamination process is used, the titanium nanotubes need to be The tubes and chitin fibers are laid in a certain order and proportion, and then laminated at a certain temperature and pressure. The lamination temperature can be controlled at 80-120°C, the pressure at 1-3MPa, and the time at 15-30 minutes. During the lamination process, it is necessary to ensure that the layers are firmly bonded, without gaps, delamination, and other problems. Regardless of whether it is a weaving or lamination process, after the composite is completed, the second middle layer structure must be carefully inspected to ensure that its quality meets the requirements. The uniformity, strength, and antibacterial properties of the composite structure can be checked through microscopic observation, mechanical property testing, and other methods. If problems are found, adjustments and improvements must be made in a timely manner to ensure that the second middle layer structure can play a good role in the waterproof board;

[0024] Step 7: Prepare the wear-resistant protective layer material. Purchase high-quality polyurethane material and check whether its wear resistance, corrosion resistance and weather resistance meet the requirements. The hardness of polyurethane can be within the range of Shore A60-80 degrees.

[0025] Step 8: Wear-resistant protective layer production: the polyurethane material is subjected to specific processes such as extrusion or spraying to form a polyurethane layer of a certain thickness on the second middle layer, i.e., the wear-resistant protective layer. The extrusion temperature can be 180-220°C, the spraying pressure can be 0.3-0.6MPa, the thickness of the polyurethane layer can be in the range of 1-3mm, and the curing time is 24-48 hours;

[0026] Step 9: Mixing and coating of weather-resistant and antibacterial layer. Preparation of weather-resistant and antibacterial layer. Accurately weigh raw materials such as nano-silver ions, zinc oxide, silicon dioxide, nano-alumina, etc. to ensure that their purity meets the requirements. For example, the purity of nano-silver ions should reach more than 99%, the purity of zinc oxide is about 98%, and the purity of silicon dioxide and nano-alumina should also be at a high level. At the same time, check the physical properties such as particle size and shape. For example, the particle diameter of nano-silver ions can be controlled in the range of 10-50 nanometers, the particle size of zinc oxide is 20-80 nanometers, the diameter of silicon dioxide particles is 30-100 nanometers, and the nano-alumina particles are 20-80 nanometers. It can be between 20-70 nanometers. Then choose equipment suitable for mixing nano-scale materials, such as a high-speed blender or an ultrasonic mixer, and pre-treat it to ensure that the interior is clean and free of impurities. It is very important to determine the optimal mixing ratio of raw materials such as nano silver ions. It is necessary to comprehensively consider the performance characteristics of each raw material and the final coating performance requirements. Generally speaking, nano silver ions can account for 5%-15% of the total mixing ratio, zinc oxide accounts for 15%-25%, silicon dioxide accounts for 20%-30%, and nano alumina accounts for 25%-35%. The ratio is continuously optimized through experiments. In the mixing process, the raw materials are added in proportion. Material, control the feeding speed, generally the feeding amount can be controlled at 5-15 grams per minute, after starting the equipment, choose the appropriate mixing time and speed according to different situations, for example, the high-speed mixer can be pre-mixed at a speed of 500-1000 revolutions per minute, after mixing for 5-10 minutes, gradually increase the speed to 1500-2500 revolutions per minute, after mixing for 20-30 minutes, reduce the speed for the final adjustment, timely sampling and testing to ensure uniform mixing, according to the needs of the appropriate amount of dispersants, stabilizers and other additives can be added to improve the dispersion of nanomaterials and the stability of the mixed system, the amount of additives added is generally controlled The amount of additives used is strictly controlled at 1%-5% of the total mixed system. After mixing, the coating is filtered to remove impurities and large particles, and then packaged to avoid contact with air and moisture. Finally, the mixed weather-resistant and antibacterial coating is fully tested for quality, including appearance, viscosity, solid content, antibacterial performance, weather resistance, etc. If it does not meet the requirements, the mixing ratio and the amount of additives are adjusted until the expected performance indicators are achieved. Then, it is coated on the wear-resistant protective layer by spraying, roller coating or dipping. The coating thickness can be in the range of 0.1-0.5 mm and the drying time is 12-24 hours.

[0027] Step 10: Overall structural processing: put the prepared layer structures into the pressing equipment and press them as a whole under a certain temperature and pressure. The temperature can be controlled at 100-130℃, the pressure at 3-5MPa, and the time at 30-60 minutes to ensure that the layers are firmly bonded to form a complete waterproof board structure. Subsequently, the waterproof board is subjected to appearance inspection, antibacterial performance test, wear resistance test and other quality inspections to ensure that the waterproof board meets the quality standards.

The lamination temperature can be controlled at 80-120℃, the pressure is 1-3MPa, and the time is 15-30 minutes. During the lamination process, it is necessary to ensure that the layers are firmly bonded without gaps, delamination, etc. Regardless of whether it is a weaving or lamination process, after the composite is completed, the second middle layer 33 structure must be carefully inspected to ensure that its quality meets the requirements. The uniformity, strength and antibacterial properties of the composite structure can be checked by microscopic observation, mechanical property testing and other methods. If problems are found, adjustments and improvements must be made in time to ensure that the second middle layer 33 structure can play a good role in the waterproof board;

[0053] Step 7: Prepare the wear-resistant protective layer 34 material, purchase high-quality polyurethane material, and check whether its wear resistance, corrosion resistance and weather resistance meet the requirements. The hardness of polyurethane can be within the range of Shore A60-80 degrees;

[0054] Step 8: manufacturing the wear-resistant protective layer 34, forming a polyurethane layer of a certain thickness, i.e., the wear-resistant protective layer 34, on the second middle layer 33 through a specific process such as extrusion or spraying of the polyurethane material, the extrusion temperature can be 180-220°C, the spraying pressure can be 0.3-0.6MPa, the thickness of the polyurethane layer can be in the range of 1-3mm, and the curing time is 24-48 hours;

[0055] Step 9: Mixing and coating of weather-resistant antibacterial layer 35. Preparation of weather-resistant antibacterial layer 35. Accurately weigh raw materials such as nano silver ions, zinc oxide, silicon dioxide, nano alumina, etc. to ensure that their purity meets the requirements. For example, the purity of nano silver ions should reach more than 99%, the purity of zinc oxide is about 98%, and the purity of silicon dioxide and nano alumina should also be at a high level. At the same time, check the physical properties such as particle size and shape. For example, the particle diameter of nano silver ions can be controlled within the range of 10-50 nanometers, the particle size of zinc oxide is 20-80 nanometers, the diameter of silicon dioxide particles is 30-100 nanometers, and the diameter of nano alumina particles is 20-80 nanometers. The particles can be between 20-70 nanometers. Then choose equipment suitable for mixing nano-scale materials, such as a high-speed blender or an ultrasonic mixer, and pre-treat them to ensure that the interior is clean and free of impurities. It is crucial to determine the optimal mixing ratio of raw materials such as nano-silver ions. It is necessary to comprehensively consider the performance characteristics of each raw material and the final coating performance requirements. Generally speaking, nano-silver ions can account for 5%-15% of the total mixing ratio, zinc oxide accounts for 15%-25%, silicon dioxide accounts for 20%-30%, and nano-alumina accounts for 25%-35%. The ratio is continuously optimized through experiments. During the mixing process, add them in proportion. Raw materials, control the feeding speed, generally the feeding amount can be controlled at 5-15 grams per minute, after starting the equipment, choose the appropriate mixing time and speed according to different situations, for example, the high-speed mixer can be pre-mixed at a speed of 500-1000 revolutions per minute, after mixing for 5-10 minutes, gradually increase the speed to 1500-2500 revolutions per minute, after mixing for 20-30 minutes, reduce the speed for the final adjustment, timely sampling and testing to ensure uniform mixing, according to the needs of the appropriate amount of dispersants, stabilizers and other additives can be added to improve the dispersion of nanomaterials and the stability of the mixed system, the amount of additives added is generally controlled The amount of additives is strictly controlled at 1%-5% of the total mixed system. After mixing, the coating is filtered to remove impurities and large particles, and then packaged to avoid contact with air and moisture. Finally, the mixed and prepared weather-resistant antibacterial coating is fully tested for quality, including appearance, viscosity, solid content, antibacterial performance, weather resistance, etc. If it does not meet the requirements, the mixing ratio and the amount of additives are adjusted until the expected performance indicators are achieved. Then, the coating is applied to the wear-resistant protective layer 34 by spraying, roller coating or dipping. The coating thickness can be in the range of 0.1-0.5 mm and the drying time is 12-24 hours.

[0056] Step 10: Overall structural processing: put the prepared layer structures into the pressing equipment and press them as a whole under a certain temperature and pressure. The temperature can be controlled at 100-130℃, the pressure at 3-5MPa, and the time at 30-60 minutes to ensure that the layers are firmly bonded to form a complete waterproof board structure. Subsequently, the waterproof board is subjected to appearance inspection, antibacterial performance test, wear resistance test and other quality inspections to ensure that the waterproof board meets the quality standards.

[0057] The working principle of the present invention is: by inserting the sliding bars 23 on both sides of the connecting plate 21 into the inner sides of the sliding grooves 22, since the sliding bars 23 and the sliding grooves 22 can be inserted and combined with each other, the clamping installation of the composite plate 1 can be quickly realized. When the installation is completed, the limiting spring 2522 will reset and push the slider 2523 to move outward. When the slider 2523 moves outward, it will drive the limiting block 2524 to be inserted into the inner side of the limiting groove 2521. Through the mutual limiting action of the slider 2523 and the limiting groove 2521, the composite plate 1 can be firmly installed and combined on both sides of the connecting plate 21. In addition, the side sealing plate 24 can effectively seal the gap between the connecting plate 21 and the composite plate 1, further ensuring the stable combination and installation of each composite plate 1, and when the composite plate 1 needs to be disassembled and separated for operation During maintenance, the armrest 2536 can be adjusted and twisted to rotate. The rotation of the adjusting armrest 2536 will drive the hinge seat 2533 to rotate, and then drive the rotating wheel 2534, the hinge wheel 2532 and the connecting piece 2535 to interact with each other. Under this linkage, the slider 2523 can be assisted to squeeze the limit spring 2522 to move it inward. When the slider 2523 moves inward, it will drive the limit block 2524 to disengage from the limit groove 2521. Once the limit groove 2521 and the limit block 2524 are separated from each other, the slide plate 22 can be quickly pulled out. At this time, the composite plate 1 can be removed from both sides of the connecting plate 21. It can be seen that during the overall use of the device, it is convenient to quickly disassemble and repair the composite plate 1 and the connecting plate 21, which greatly facilitates the use of the device.

[0058] The weather-resistant and antibacterial layer 35 is composed of a composite of nano silver ions, zinc oxide, silicon dioxide and nano aluminum oxide, and has extremely strong antibacterial ability. Nano silver ions can effectively inhibit the growth of bacteria and molds, and provide reliable sanitation protection for the use environment. At the same time, the weather-resistant and antibacterial layer 35 also has excellent weather resistance, and can effectively resist the influence of external factors such as ultraviolet rays and temperature changes, ensuring that the waterproof board can maintain stable performance in various complex environments. Secondly, the wear-resistant protective layer 34 adopts a polyurethane layer, which has excellent wear resistance and can effectively prevent the waterproof board from being worn during use, thereby greatly extending the service life of the waterproof board. Furthermore, the second middle layer 33 is composed of a composite of titanium nanotubes and chitin fibers. The titanium nanotubes The strength and stability of the material are greatly enhanced, while the chitosan fiber gives the layer natural antibacterial properties, further improving the overall antibacterial effect of the waterproof board. The aerogel layer of the first middle layer 32 has excellent thermal insulation and heat preservation properties, which can effectively reduce heat transfer and reduce energy consumption. At the same time, the high porosity and low density of the aerogel also give it a certain sound absorption and noise reduction function. Finally, the inner layer 31 adopts antibacterial and mildew-proof polyvinyl chloride, which provides reliable antibacterial and mildew-proof protection in the position in direct contact with the protected object, and can effectively prevent bacterial growth and material damage caused by moisture and the like. In summary, this waterproof board combines multiple advantages such as antibacterial, wear-resistant, heat-insulating, and heat-preserving, and has extremely broad application prospects.
