Description

Technical Field

[0001] This invention belongs to the field of composite material technology, specifically relating to a material for an anti-clogging washing device and its preparation method. Background Technology

[0002] In chemical production processes, product collection typically involves processes such as spraying and washing. As production progresses, impurities accumulate in the washing process packing, causing blockages and hindering product flow. This necessitates frequent disassembly of the washing tower and cleaning of the packing, impacting production. For example, in the preparation of hydrogen fluoride from fluorite powder and concentrated sulfuric acid, washing and distillation purification are required to obtain the final product, anhydrous hydrogen fluoride. Since the fluorite powder is dried and then fed into the reactor, some dust particles that did not participate in the reaction, along with solid impurities generated during the reaction, easily deposit and accumulate at bends, diameter changes, or gentle transition sections of the pipeline. Over time, this accumulation thickens, eventually leading to pipeline blockage. Therefore, on the one hand, honeycomb packing or spraying methods are needed to ensure stable production; on the other hand, purging, vibration, or buffering devices are typically installed at easily clogged areas to prevent blockages. Previously, metal gaskets were commonly used to reduce the impact of vibration on the equipment, but metal materials have poor corrosion resistance and require frequent replacement, affecting production efficiency.

[0003] Nylon, as one of the five major general-purpose engineering plastics, not only possesses excellent mechanical properties, but also good wear resistance, self-lubrication, and weather resistance. Furthermore, it is non-toxic and easy to process and mold. Therefore, nylon is widely used in automotive parts, instruments, communication electronics, packaging materials, and other fields. Especially in the chemical production field, with the recent trend towards lightweight and high-performance materials, many equipment components have been replaced by high-performance plastics, and nylon can replace metal materials in system components, drive shafts, brakes, and sliding parts requiring low friction coefficients. As modern society places increasingly higher demands on the high-temperature resistance of nylon materials, the definition of high-temperature nylon is also changing. Generally, high-temperature nylon must meet the requirement of being able to be used at 150℃ for a period of time. High-temperature resistant nylon not only possesses excellent properties such as wear resistance, heat resistance, corrosion resistance, fatigue resistance, and high-temperature resistance, but it can also significantly reduce the material's water absorption and shrinkage rate, while giving the product excellent dimensional stability and good impact resistance. Chinese invention patent CN120818237A discloses a high-temperature resistant, high-toughness modified nylon composite material and its preparation method. The modified nylon composite material comprises the following components in parts by weight: 40-60 parts PA6T, 20-30 parts PA9T, 10-25 parts maleic anhydride graft compound, 5-10 parts modified montmorillonite, 0.1-1 parts antioxidant, and 3-15 parts flame retardant. The resulting modified nylon composite material exhibits high toughness, good high-temperature resistance, and is not easily cracked under impact or vibration, nor easily deformed under long-term heat load; it also possesses good flame retardant properties, high safety, and strong dimensional stability. While the aforementioned patented technology improves the impact toughness of the nylon composite material, its mechanical strength is significantly reduced, making it unsuitable for use in anti-clogging washing devices. Summary of the Invention

[0004] The purpose of this invention is to provide a material for an anti-clogging washing device and its preparation method. The material for the anti-clogging washing device uses long-chain semi-aromatic nylon 12T as the matrix resin, making full use of the high temperature resistance and corrosion resistance of nylon 12T. The modified nylon 12T composite material not only has good tensile strength, but its impact toughness has also been greatly improved. It can be widely used in the field of organic chemical production, and is particularly suitable as a shock-absorbing and buffering material for anti-clogging washing devices.

[0005] To achieve the above objectives, a first aspect of the present invention provides a material for an anti-clogging washing device, comprising the following components in parts by weight:

[0006] Nylon 12T 80-100 parts, inorganic fiber filler 20-30 parts, toughening agent 5-10 parts, diatomaceous earth micro powder 10-15 parts, sarin resin 3-6 parts, graphene 1-3 parts, antioxidant 0.5-2 parts, lubricant 0.5-2 parts, coupling agent 0.5-2 parts.

[0007] Nylon 12T, as a novel high-temperature resistant material, boasts excellent comprehensive performance and therefore has broad application prospects. To further expand the application range of Nylon 12T, inorganic fiber fillers can be selected for reinforcement modification. Inorganic fiber fillers are high-temperature resistant materials; the heat resistance of the thermoplastic resin reinforced with them is significantly increased compared to the unreinforced version. Simultaneously, inorganic fiber fillers restrict the movement of polymer chains within the resin, which can significantly reduce the shrinkage rate of the reinforced plastic and improve its rigidity. However, simply using inorganic fiber fillers to reinforce Nylon 12T can lead to a decrease in the toughness of the composite material, making it difficult to meet the material requirements for anti-clogging washing devices.

[0008] Therefore, this invention adds a certain amount of diatomaceous earth micropowder and sarin resin reinforcing filler to the fiber-reinforced nylon 12T system. Diatomaceous earth micropowder, as the main reinforcing and toughening filler, not only reduces the cost of the composite material but also improves its dimensional stability. As a rigid particle with a porous structure, the porous structure of diatomaceous earth micropowder acts as a physical filler, increasing the modulus and hardness of nylon 12T and forming physical entanglements with it, thus enhancing toughness. Simultaneously, the porous structure of diatomaceous earth micropowder not only improves the interfacial properties with nylon 12T but also acts as a buffer, improving the impact toughness of the composite material. Furthermore, during melt blending, the macromolecular chains of nylon 12T can penetrate into the micropores on the surface of the diatomaceous earth. After cooling and molding, these molecular chains are filled within the pores, forming numerous physical entanglement points. This mechanical interlocking effectively restricts the slippage of the polymer chains under external forces, thereby improving the rigidity and strength of the composite material. When the material is impacted, cracks encounter the porous diatomaceous earth particles during propagation. The presence of particles disperses stress concentration at crack tips, hindering crack propagation. More importantly, the interface between diatomaceous earth particles and the matrix can induce numerous microcracks (crazing) and shear bands in the matrix. These processes require significant impact energy, thus significantly improving the material's toughness. The particle size of the diatomaceous earth powder is not particularly limited, commonly ranging from 0.5-5µm. Specifically, considering both interfacial bonding with nylon 12T resin and the reinforcing and toughening effects, the particle size is further optimized to 2-4µm.

[0009] Sarin resin can toughen and improve the processability of nylon 12T. As an ionomer, the ionic cross-linked regions in its molecular chain can deform and induce crazing upon impact, absorbing a large amount of energy; at the same time, it can improve the dispersibility of diatomaceous earth powder and graphene filler. Graphene, as a two-dimensional sheet structure material, can synergistically enhance toughness and improve overall performance.

[0010] In summary, diatomaceous earth provides a rigid framework at the micrometer scale, while graphene constructs a reinforcing network at the nanometer scale, forming a multi-level reinforcing structure. The high specific surface area of ​​graphene can bridge the diatomaceous earth micropowder, improving interfacial stress transmission. Meanwhile, sarin resin (ionomer), as a flexible phase, can absorb energy during deformation under stress; graphene, as a rigid nanofiller, can induce shear yielding in the matrix. The interaction of these fillers achieves a balance between rigidity and toughness in the Nylon 12T composite material.

[0011] In one embodiment, the inorganic fiber filler is one or more of glass fiber, carbon fiber, and boron fiber. Specifically, glass fiber, with its excellent rigidity and toughness, can be selected. The inorganic fiber filler, acting as a skeleton dispersed in the nylon 12T matrix, bears most of the external stress, greatly improving the material's strength and rigidity. Simultaneously, the presence of the inorganic fiber filler also promotes the dispersion of diatomaceous earth micropowder in the nylon 12T resin system.

[0012] In one embodiment, the inorganic fiber filler is alkali-free glass fiber.

[0013] In one embodiment, the toughening agent is one or more of maleic anhydride-grafted polystyrene, maleic anhydride-grafted polyphenylene ether, maleic anhydride-grafted polypropylene, maleic anhydride-grafted polyethylene, maleic anhydride-grafted ethylene-octene copolymer, maleic anhydride-grafted ethylene propylene diene monomer (EPDM) rubber, and maleic anhydride-grafted SEBS. This invention uses a maleic anhydride toughening agent containing polar groups as a modified filler for nylon 12T. It can not only form hydrogen bonds with nylon 12T but also form ionic crosslinks with metal ions in sarin resin, further improving the impact resistance of the composite material. Specifically, the toughening agent is used in an amount of 6-8 parts; an appropriate amount of toughening agent can fully exert its toughening effect and improve the overall performance of the composite material.

[0014] In one embodiment, the sarin resin is one or more of sarin resin 8920, sarin resin 8945, sarin resin 9910, and sarin resin 9320.

[0015] In one embodiment, the antioxidant is one or more of antioxidant 1010, antioxidant 168, antioxidant 264, antioxidant TNP, and antioxidant TPP.

[0016] In one embodiment, the lubricant is one or more of pentaerythritol stearate, metal stearate, polytetrafluoroethylene, silicone oil, talc, and polyethylene wax.

[0017] In one embodiment, the coupling agent is one or more of KH550, KH560, KH570, A-174, and A-187.

[0018] In one embodiment, a material for an anti-clogging washing device comprises the following components in parts by weight:

[0019] The composite material consists of 85-95 parts Nylon 12T, 23-27 parts inorganic fiber filler, 6-8 parts toughening agent, 11-14 parts diatomaceous earth micropowder, 4-5 parts sarin resin, 1.5-2.5 parts graphene, 0.5-2 parts antioxidant, 0.5-2 parts lubricant, and 0.5-2 parts coupling agent. By adjusting the content of each component, especially the amount of diatomaceous earth micropowder with a larger particle size, its filling effect can be fully utilized, further improving the impact resistance of the composite material while maintaining high strength performance. Among them, graphene, as a nanoscale filler, mainly plays a role in constructing a reinforcing network at the nanoscale, supplementing the micron-scale rigid skeleton of diatomaceous earth and forming a multi-level reinforcing structure. Due to the inherent defects of nanofillers, the graphene content should not be too high, otherwise agglomeration may easily occur, which may act as stress concentration points, leading to a decrease in the mechanical properties of the composite material.

[0020] On the other hand, the present invention also provides a method for preparing a material for an anti-clogging washing device, comprising the following steps:

[0021] (1) All raw materials except inorganic fiber filler are premixed evenly and fed from the main feed port of the twin-screw extruder. Inorganic fiber filler is added through the side feed port.

[0022] (2) Melt, extrude and granulate to obtain a material for an anti-clogging washing device.

[0023] In one embodiment, the twin-screw extruder has a screw speed of 400-600 r / min and an extrusion temperature of 300-330°C.

[0024] Beneficial effects:

[0025] This invention adds a certain amount of diatomaceous earth micropowder and sarin resin as reinforcing fillers to a fiber-reinforced nylon 12T system. As a rigid particle with a porous structure, the porous structure of diatomaceous earth micropowder acts as a physical filler, improving the modulus and hardness of nylon 12T and forming physical entanglements with it, thus enhancing toughness. Simultaneously, the porous structure of diatomaceous earth micropowder not only improves the interfacial properties with nylon 12T but also acts as a buffer, improving the impact toughness of the composite material. Salin resin can toughen and improve the processability of nylon 12T. As an ionomer, the ionic cross-linked regions in the sarin resin molecular chain can deform and induce crazing upon impact, absorbing a large amount of energy; it can also improve the dispersibility of diatomaceous earth micropowder and graphene fillers. Graphene, as a two-dimensional sheet nanostructure material, can synergistically enhance and toughen the composite, improving its overall performance. Detailed Implementation

[0066] Comparative Example 2

[0067] A material for an anti-clogging washing device comprises the following components in parts by weight:

[0068] The composition includes 90 parts Nylon 12T, 25 parts alkali-free glass fiber, 8 parts toughening agent (maleic anhydride-grafted ethylene-octene copolymer), 13 parts diatomaceous earth micropowder (average particle size 2.5µm), 5 parts Sarin resin 9320, 6 parts graphene, 1.5 parts antioxidant 1010, 1.5 parts lubricant (talc), and 1.5 parts coupling agent (KH550). Tests show that the material has a tensile strength of 205MPa, a flexural strength of 223MPa, and a notched impact strength of 9.7kJ / m. 2 .

[0069] As can be seen from the above examples and comparative examples, diatomaceous earth powder, as the main reinforcing and toughening filler, can not only reduce the cost of composite materials but also improve their dimensional stability. As a rigid particle with a porous structure, the porous structure of diatomaceous earth powder can act as a physical filler, increasing the modulus and hardness of Nylon 12T and forming physical entanglements with it, thus enhancing toughness. Salin resin can toughen and improve the processability of Nylon 12T. As an ionomer, the ionic cross-linked regions in its molecular chains can deform and induce crazing under impact, absorbing a large amount of energy; it can also improve the dispersibility of diatomaceous earth powder and graphene filler. Graphene, as a two-dimensional sheet nanostructure material, can synergistically reinforce and toughen, improving overall performance. In summary, diatomaceous earth provides a rigid framework at the micrometer scale, while graphene constructs a reinforcing network at the nanometer scale, forming a multi-level reinforcing structure. The high specific surface area of ​​graphene can bridge diatomaceous earth powder, improving interfacial stress transmission. Sarin resin (ionomer), as a flexible phase, can absorb energy when deformed under stress; graphene, as a rigid nanofiller, can induce shear yielding of the matrix. The combination of these fillers achieves a balance between rigidity and toughness in the nylon 12T composite material.

[0070] Specifically, compared to Example 10, the amounts of diatomaceous earth powder and sarin resin were interchanged in Comparative Example 1, meaning that the amount of diatomaceous earth powder was excessive while the amount of sarin resin was insufficient. In this case, the reinforcing and toughening effects of the diatomaceous earth powder were insufficient; and the excessive amount of sarin resin enhanced the ionic cross-linking effect, leading to increased melt viscosity, processing difficulties, uneven dispersion of inorganic fillers, and a decrease in the mechanical properties of the composite material. Compared to Example 10, the excessive amount of graphene in Comparative Example 2 resulted in little change in tensile and flexural strength, but a significant decrease in notched impact strength. This is because, as a nanofiller, excessive graphene content easily leads to uneven dispersion and agglomeration, failing to enhance the network and affecting product performance.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
