Abstract
Description
Technical Field
[0001] This invention relates to the field of polymer composite materials technology, and in particular to a polymer composite wire harness and a polymerization system for preparing PMMA composite materials using the same. Background Technology
[0002] Polymethyl methacrylate (PMMA), a transparent polymer material with excellent comprehensive performance, has been widely used in traffic noise barriers, transparent buildings, thermal insulation curtain walls, and aircraft windows. Specifically, taking noise reduction facilities for high-speed rail or urban rail transit as an example, if PMMA sheets of a predetermined thickness are used alone as the main material of the sound barrier, there are dual risks related to traffic safety and the ecological environment. The former mainly manifests in the fact that the hard and brittle nature of PMMA makes it prone to generating a large number of flying debris upon impact, endangering the safety of pedestrians and vehicles on nearby or below roads. The latter mainly considers the risk of birds accidentally colliding with the transparent sheets during flight due to their difficulty in identifying them.
[0003] To address this, existing technology incorporates black wire bundles at appropriate intervals into the PMMA composite material during the manufacturing process. This moderately improves impact resistance while creating a drag effect to reduce debris splashing or falling, and the black wire bundles are easily identifiable by birds, thus resolving the aforementioned hazards.
[0004] Nevertheless, in the current technology, the path of using only black wire harnesses still shows certain deficiencies in terms of interface bonding ability. A small number of wire harnesses detach from the PMMA matrix, resulting in whitening after the two phases separate, which reduces the service life of PMMA composite materials. Utility Model Content
[0005] The purpose of this application is to provide a polymer composite wire harness and a polymerization system for preparing PMMA composite materials using the same, aiming to solve the problem that the interfacial bonding ability is insufficient when using black wire harness alone, resulting in a low service life of PMMA composite materials obtained by using it as a reinforcement.
[0006] To achieve the above objectives, this application provides a polymer composite wire harness, comprising: a wire harness core material, a braided layer, and a covering layer, wherein the braided layer at least partially covers the wire harness core material, and the covering layer at least partially covers the braided layer, so that the braided layer is fixed on the wire harness core material.
[0007] Optionally, the braided layer completely covers the wire harness core material, and the covering layer completely covers the braided layer.
[0008] Optionally, there are multiple braided layers, which are spaced apart from each other and wrap around the wire harness core material. The covering layer covers both ends of the multiple braided layers.
[0009] Optionally, there are multiple braided layers and multiple covering layers, with the multiple braided layers wrapping around the wire harness core material at intervals, and the multiple covering layers completely covering the multiple braided layers respectively.
[0010] Optionally, there are multiple covering layers, and the braided layer completely covers the wire harness core material, with the multiple covering layers overlapping each other on the braided layer.
[0011] Optionally, the core material of the wire harness is made of nylon, modified nylon, or ultra-high molecular weight polyethylene.
[0012] Optionally, the material of the braided layer is polyester, nylon, spandex, polypropylene, aramid, glass fiber, carbon fiber or metal wire.
[0013] Optionally, the coating layer is made of polyester resin, epoxy resin, acrylic resin, or polyurethane resin.
[0014] This application also provides a polymerization system, including a mold, a liquid phase material, and a polymer composite wire bundle as described above. The number of polymer composite wire bundles is multiple, and the multiple polymer composite wire bundles are fixed at intervals in the mold. The liquid phase material is poured into the mold and completely covers the polymer composite wire bundles, thereby allowing the mold filled with the liquid phase material to undergo a polymerization reaction to obtain a plate with the polymer composite wire bundles embedded in it.
[0015] Optionally, the mold includes an upper template, an elastic frame, and a lower template. The elastic frame is sandwiched between the upper template and the lower template. Multiple sets of parallel through holes are centrally formed on the two opposite side walls of the elastic frame. The spacing between any two adjacent through holes is equal. The two ends of the polymer composite wire bundle are respectively disposed in the through holes.
[0016] This application involves coating a braided layer onto the surface of the wire harness core material, and then coating the surface of the braided layer with a covering layer to fix the braided layer onto the wire harness core material, thereby obtaining a polymer composite wire harness. In this way, the liquid material used to prepare the PMMA composite material can be fully bonded to both the braided layer and the covering layer. The PMMA composite material made using this polymer composite wire harness overcomes the defect in existing technologies where the wire harness core material alone easily detaches from the PMMA matrix, avoids the whitening phenomenon after two-phase separation, and extends the service life of the PMMA composite material.

[0029] Please refer to Figure 1 , Figure 1 A schematic front view of a polymer composite wire harness 1 is shown (I), including: a wire harness core material 11, a braided layer 12, and a covering layer 13. The braided layer 12 at least partially covers the wire harness core material 11, and the covering layer 13 at least partially covers the braided layer 12, so that the braided layer 12 is fixed to the wire harness core material 11. Specifically, in this embodiment, the braided material can be tightly wrapped around the surface of the wire harness core material 11 in a circular manner according to a specific braiding texture, either manually or with a braiding device, thereby forming a braided layer 12 with a certain textured pattern. Furthermore, by partially covering the braided layer 12 with a covering layer 13, the braided layer 12 partially covering the wire harness core material 11 is fixed to the wire harness core material 11, effectively preventing the braided layer 12 from falling off the wire harness core material 11 in subsequent use steps.
[0030] The black wire bundles used in existing technologies are typically made of nylon. In the actual preparation of PMMA composites, the degree of bonding between the nylon black wire bundles and the liquid MMA monomers is also related to the ambient temperature. With seasonal changes, the yield of PMMA composites obtained through polymerization reactions can fluctuate, easily causing a small number of wire bundles to detach from the PMMA matrix, resulting in whitening after phase separation and affecting the lifespan of the substrate.
[0031] It is easy to understand that by replacing the existing black wire bundle with the polymer composite wire bundle 1 obtained through the above embodiments, compared with the prior art, during the preparation of PMMA composite materials, the liquid MMA monomer can fully wet the braided layer 12 and enter the textured spatial structure formed by the braided layer 12. At the same time, it can also form a better interfacial bonding ability with the coating layer 13 due to the similar chemical properties. Thus, after the polymerization reaction is completed, due to the synergistic cooperation between the braided layer 12 and the coating layer 13, the solid PMMA formed can achieve all-round bonding with the polymer composite wire bundle 1, increasing the contact area during bonding, completely avoiding the interference caused by daily fluctuations in room temperature, overcoming the defect of the prior art where the black wire bundle is easy to detach from the PMMA matrix, avoiding the whitening between the two phases, and extending the service life of the PMMA composite material.
[0032] Optionally, the braided layer 12 completely covers the wire harness core material 11, and the covering layer 13 completely covers the braided layer 12. Specifically, in this embodiment, the length of the covering layer 13 is equal to the length of the braided layer 12, which is equal to the length of the wire harness core material 11. That is, the wire harness core material 11 is completely and tightly covered by the braided layer 12, and the braided layer 12 is completely and tightly covered by the covering layer 13. In this way, the braided layer 12 provides sufficient surface friction to the covering layer 13, and the covering layer 13 is used to combine with the liquid MMA monomer. After the polymerization reaction is completed, a PMMA composite material in which the covering layer 13 is fully bonded to the solid PMMA is obtained.
[0033] Please refer to Figure 2 There are multiple braided layers 12, which are spaced apart and wrapped around the core material 11. A covering layer 13 is wrapped around both ends of the multiple braided layers 12. Specifically, in this embodiment, multiple braided layers 12 are wound at intervals on the surface of the core material 11. The spacing between the multiple braided layers 12 can be equal or unequal. A covering layer 13 is wrapped around both ends of each braided layer 12. In this way, each braided layer 12 can be fixed on the core material 11, and the central region can be used to combine with liquid MMA monomer. After the polymerization reaction is completed, a PMMA composite material with the covering layer 13, the braided layer 12 and solid PMMA combined is obtained.
[0034] Please refer to Figure 3 There are multiple braided layers 12 and multiple covering layers 13. The multiple braided layers 12 are wrapped around the core material 11 at intervals, and the multiple covering layers 13 completely cover the multiple braided layers 12. Specifically, in this embodiment, multiple braided layers 12 are wound at intervals on the surface of the core material 11. The spacing between the multiple braided layers 12 can be equal or unequal. Each braided layer 12 is completely covered by a covering layer 13. In this way, each braided layer 12 can be fixed on the core material 11. At this time, each braided layer 12 is used to provide sufficient surface friction to the covering layer 13. Each covering layer 13 and the exposed core material 11 are used to contact the liquid MMA monomer. After the polymerization reaction is completed, a PMMA composite material is obtained by combining the covering layer 13, the core material 11 and the solid PMMA.
[0035] Please refer to Figure 4 There are multiple covering layers 13, and the braided layer 12 completely covers the wire harness core material 11. The multiple covering layers 13 are spaced apart and covered on the braided layer 12. Specifically, in this embodiment, the length of the braided layer 12 is equal to the length of the wire harness core material 11, so that the braided layer 12 can completely cover the wire harness core material 11. The multiple covering layers 13 are spaced apart and covered on the braided layer 12. The spacing between the multiple covering layers 13 can be equal or unequal. In this way, the entire braided layer 12 can be fixed on the wire harness core material 11. Each covering layer 13 and the braided layer 12 exposed between every two covering layers 13 are in contact with the liquid MMA monomer. After the polymerization reaction is completed, a PMMA composite material is obtained by combining the covering layer 13, the braided layer 12 and the solid PMMA.
[0036] Optionally, the wire harness core material 11 can be made of at least one of nylon, modified nylon, and ultra-high molecular weight polyethylene. It is understood that the above-mentioned materials all possess advantages such as high strength, high toughness, high wear resistance, high impact strength, and good fatigue resistance. Thus, by using the wire harness core material 11 made of at least one of the above materials to prepare PMMA composite materials, the resulting PMMA composite material will possess excellent tensile strength and impact strength.
[0037] Optionally, the braided layer 12 can be made of at least one of polyester, nylon, spandex, polypropylene, aramid, glass fiber, carbon fiber, and metal wire. It is understood that the above materials possess advantages such as high strength, high toughness, high abrasion resistance, high durability, high elasticity, and high temperature resistance. For example, if polyester and nylon are selected, the resulting braided layer 12 combines high strength and high abrasion resistance; if spandex and polyester are selected, the resulting braided layer 12 combines high elasticity and abrasion resistance; if aramid and glass fiber are selected, the resulting braided layer 12 combines high temperature resistance and chemical corrosion resistance; if carbon fiber and metal wire are selected, the resulting braided layer 12 combines high strength and electrical conductivity. Thus, at least one of the above materials can be adaptively selected to prepare the braided layer 12 according to the actual application scenario of the PMMA composite material, thereby obtaining a polymer composite wire harness 1 with optimal functional adaptability.
[0038] Optionally, the coating layer 13 can be made from at least one of polyester resin, epoxy resin, acrylic resin, and polyurethane resin. It is understood that the above materials possess advantages such as abrasion resistance, chemical corrosion resistance, weather resistance, high strength, high adhesion, high elasticity, and high flexibility. For example, if polyester resin and epoxy resin are selected, the resulting coating layer 13 simultaneously possesses the weather resistance and abrasion resistance provided by polyester resin and the high strength and high adhesion provided by epoxy resin; if acrylic resin and polyurethane resin are selected, the resulting coating layer 13 simultaneously possesses the optical properties and weather resistance provided by acrylic resin and the high elasticity and abrasion resistance provided by polyurethane resin. Thus, at least one of the above can be adaptively selected to prepare the coating layer 13 according to the actual application scenario of the PMMA composite material, thereby obtaining a polymer composite wire harness 1 with optimal functional compatibility.
[0039] Optionally, the wire harness core material 11 can be a long cylindrical strip with a circular cross-section, and its diameter is preferably less than or equal to 5 mm (and greater than 0.5 mm), for example, it can be 1.7 mm, 2.4 mm, 3.5 mm, 4.8 mm, 5 mm, etc., and is not limited to a single value. By limiting the diameter of the wire harness core material 11 to the above range, it is possible to ensure that the wire harness core material 11 has sufficient mechanical strength while also having sufficient toughness, thereby effectively extending its service life.
[0040] Optionally, the thickness of the braided layer 12 is preferably 0.01~1.5 mm, for example, it can be 0.01 mm, 0.06 mm, 0.09 mm, 0.1 mm, 0.63 mm, 0.79 mm, 0.99 mm, 1.1 mm, 1.35 mm, 1.47 mm, or 1.5 mm, and is not limited to any single value. By limiting the thickness of the braided layer 12 to the above range, it is ensured that the braided layer 12 is fully impregnated with the liquid MMA monomer, thereby achieving the purpose of omnidirectional bonding between the solid PMMA formed in subsequent processes and the braided layer 12.
[0041] Please refer to Figure 5 , Figure 5 A schematic diagram of the spatial decomposition structure of a polymerization system is shown, including a mold 300, a liquid phase material (not shown in the figure), and a polymer composite wire bundle 1 as described above. There are multiple polymer composite wire bundles 1, which are fixed at intervals within the mold 300. The liquid phase material (not shown in the figure) is poured into the mold 300 (after the pouring is completed, the mold 300 is a closed structure, that is, the upper template 310, the elastic frame 320 and the lower template 330 that make up the mold 300 are completely sealed to each other), and completely covers the polymer composite wire bundle 1. Then, the mold 300 filled with liquid phase material (not shown in the figure) undergoes a polymerization reaction to obtain a plate containing the polymer composite wire bundle 1. Specifically, in this embodiment, the mold 300 has a cubic structure, and multiple polymer composite wire bundles 1 are fixed at intervals inside the cavity formed by the mold 300. After the liquid phase material (not shown in the figure) is poured into the cavity, the multiple polymer composite wire bundles 1 are completely immersed and filled into the entire cavity. Then, a polymerization reaction is carried out on the mold 300 filled with liquid phase material (not shown in the figure), and after the reaction is completed, a plate with embedded polymer composite wire bundles 1 is obtained, that is, PMMA composite material.
[0042] Optionally, the mold 300 includes an upper template 310, an elastic frame 320, and a lower template 330. Multiple sets of parallel through holes 325 are centrally located on the two opposite sidewalls of the elastic frame 320, with equal spacing between any two adjacent through holes 325. The two ends of the polymer composite wire bundle 1 are respectively disposed within the through holes 325. Specifically, in this embodiment, multiple sets of parallel through holes 325 are spaced apart along the length of the two opposite sidewalls of the elastic frame 320. For the multiple through holes 325 on a single sidewall, the spacing between any two adjacent through holes 325 is equal. Furthermore, when the two ends of the polymer composite wire bundle 1 are respectively interference-fitted into the through holes 325 on the two sidewalls, the multiple polymer composite wire bundles 1 can be fixed in the mold 300 at equal intervals along the length of the sidewalls. Thus, compared to the polymer composite wire bundles 1 being scattered within the mold 300, the PMMA composite material made from the equally spaced polymer composite wire bundles 1 possesses better tensile strength and impact resistance.
