Description

Technical Field

[0001] This utility model specifically relates to a continuous metallization preparation device for fiber woven fabric, belonging to the field of fiber fabric metallization technology. Background Technology

[0002] Metal composite fiber woven fabrics possess characteristics such as lightweight, high strength, corrosion resistance, and electromagnetic interference resistance, and are widely used in electromagnetic protection and other fields. The preparation of metal composite fiber woven fabrics generally involves first using non-metallic fibers as a substrate, then metallizing them to prepare metal composite fiber bundles, which are then woven into a metal composite fiber fabric. This method has the following problems: 1. Low production efficiency and high cost of metal composite fiber bundles; 2. During the metallization and weaving processes of the fiber bundles, the fibers are easily worn, leading to fuzzing of the woven fabric; 3. The contact at the intersections of the metal composite fibers is conductive, making it difficult to stably and effectively form a fiber conductive network. Alternatively, metal composite fiber woven fabrics can be prepared by directly metallizing and depositing metal onto a non-metallic fiber woven fabric substrate. However, this method involves processes such as vacuum evaporation plating, ion plating, or magnetron sputtering in actual production, significantly increasing equipment investment and production costs, and also making the production operation more difficult.

[0039] In view of the shortcomings of the prior art, the inventors of this case, through long-term research and extensive practice, have proposed the technical solution of this utility model. The following will further explain and illustrate the technical solution, its implementation process, and its principles in conjunction with the accompanying drawings and specific implementation examples.

[0040] In a typical implementation case, please refer to Figure 1A continuous metallization preparation apparatus for woven fiber fabric includes an unwinding module 100, a heat treatment module 200, a pretreatment module 300, a metal chemical deposition module 400, an electrodeposition module 500, a drying module 600, and a winding module 700 arranged sequentially along a selected direction. The unwinding module 100 carries a roll of unmetallized woven fiber fabric, and the winding module 700 provides power to drive the woven fiber fabric along the selected direction so that the woven fiber fabric passes sequentially through the heat treatment module 200, the pretreatment module 300, the metal chemical deposition module 400, the electrodeposition module 500, and the drying module 600, and winds up the metallized woven fiber fabric. The heat treatment module 200, the pretreatment module 300, the metal chemical deposition module 400, and the electrodeposition module 500 cooperate to achieve the metallization treatment of the woven fiber fabric, and the drying module 600 is used to dry the metallized woven fiber fabric.

[0041] Specifically, the woven fabric can be made of carbon fiber, aramid fiber, glass fiber, quartz fiber, polyimide fiber or PBO fiber, or non-woven fabric or fiber felt formed from the above fibers. However, the woven fabric cannot be directly subjected to metal chemical deposition, and non-conductive fibers other than carbon fiber cannot be electrodeposited / electroplated. Therefore, the woven fabric needs to be treated sequentially by the heat treatment module 200 and the pretreatment module 300 to achieve surface catalytic activation of the woven fabric. After metal chemical deposition, the fibers can be better subjected to electrodeposition and achieve continuous and efficient metallization treatment.

[0042] Specifically, the unwinding module 100 includes one or more freely rotatable unwinding rollers, which can be mounted on an unwinding frame. The unwinding rollers are used to fix the woven fabric roll, and the woven fabric roll can rotate together with the unwinding rollers. The winding module 700 includes one or more winding rollers and a rotary drive mechanism. The winding rollers and the rotary drive mechanism are connected in a transmission relationship. The winding rollers can rotate under the drive of the rotary drive mechanism to achieve the traction and collection of the woven fabric roll. The winding module 700 and the unwinding module 100 cooperate to achieve the driving, moving, transferring, and collecting of the woven fabric roll. Specifically, the unwinding module 100 may also include a speed adjustment mechanism for adjusting the speed of the unwinding rollers. By adjusting the speed of the unwinding rollers, the tension and unwinding rate of the woven fabric roll during movement can be adjusted. Specifically, the unwinding module 100 may also include a drive mechanism, which is connected in a transmission relationship with the unwinding rollers and drives the unwinding rollers to rotate, that is, the unwinding module 100 can rotate actively. Preferably, the unwinding module 100 may further include guide rollers for guiding the fiber-woven fabric roll to maintain a straight path. It should be noted that the structure and configuration of the unwinding roller, unwinding frame, guide roller, and speed adjustment mechanism are all known in the art and are not specifically limited here. Specifically, the winding module 700 may further include guide rollers for guiding the conductive fibers to maintain a straight path.

[0043] Specifically, the woven fabric can be a woven fabric formed from carbon fiber, aramid fiber, glass fiber, quartz fiber, polyimide fiber, or PBO fiber, or a nonwoven fabric or fiber felt made of the above-mentioned fibers. Specifically, the unwinding module 100 can control the release rate of the woven fabric by the surface tension of the woven fabric. Specifically, the tension of the woven fabric during release is 1 to 100 N, and the release rate can be 0.01 to 3 m / min; the width of the woven fabric can be 0.1 to 1.0 m, and the thickness of the woven fabric can be 0.1 to 1.0 mm.

[0044] Specifically, before metallization, the woven fabric needs to be heat-treated to remove the sizing agent or impurities from its surface. The heat treatment module 200 is used to remove the sizing agent or oil stains from the surface of the woven fabric. Specifically, the heat treatment module 200 may include a heat treatment chamber and a heat source disposed in the heat treatment chamber. The heat source is preferably disposed on the upper and lower sides of the woven fabric's travel path. Specifically, the heat source may be an electric heating wire, etc., without specific limitations. The woven fabric remains horizontal and passes through the heat treatment module 200 at a uniform speed. For example, the heat treatment temperature may be 100℃ to 600℃, and the heat treatment time may be 1 minute to 1 hour.

[0045] Specifically, the pretreatment module 300 is used to immerse the woven fabric 001 in a pretreatment liquid phase system, thereby catalyzing and activating the fibers on the surface and inside of the woven fabric. This causes the fiber surface to adsorb active particles or form oxide functional groups, enhancing the chemical deposition rate of the metal to be plated / deposited on the woven fabric bundle. For more details, please refer to [link to relevant documentation]. Figure 1 and Figure 2 The pretreatment module 300 includes a pretreatment chamber 310, a first guide roller group 320, and two first extrusion roller groups 330.

The first guide roller group 320 is used to guide the woven fabric to be immersed in the pretreatment liquid phase system and pass through the pretreatment chamber 310. For example, the immersion time of the woven fabric in the pretreatment liquid phase system is 1 to 3 minutes, and the temperature of the pretreatment liquid phase system is 25 to 35°C.

[0046] Specifically, the first guide roller group 320 includes three first guide rollers arranged in parallel and at intervals along a selected direction. One selected first guide roller, located in the middle region, is situated within the pretreatment chamber 310 and immersed in the pretreatment liquid phase system. The other two first guide rollers are positioned at opposite ends of the pretreatment chamber 310. The selected first guide roller is movably fitted with the pretreatment chamber 310, and its position in the depth direction of the pretreatment chamber 310 is adjustable. Specifically, to reduce wear between the woven fabric and the first guide rollers during travel, it is preferable that the first guide rollers are rotatable around their own axes. Specifically, the first guide rollers can be directly mounted on the pretreatment container containing the pretreatment chamber 310, or a separate first guide bracket can be provided for mounting the first guide rollers; no specific limitations are imposed here.

[0047] Specifically, each first compression roller group 330 includes two parallel first compression rollers. The woven fabric can pass through the gap between the first compression rollers, and compression is achieved during the passage through this gap. Through the compression of the first compression roller group 330, a large amount of moisture inside the woven fabric can be removed and it can be flattened. Specifically, the pretreatment module 300 also includes two first liquid collection chambers 340. Each first liquid collection chamber 340 is correspondingly disposed below a first compression roller group 330 and is used at least to collect the liquid that seeps out through the compression of the first compression roller group 330. Preferably, the first liquid collection chamber 340 can be integrated with the pretreatment chamber 310 in the same pretreatment container.

[0048] Specifically, the metal chemical deposition module 400 is used to chemically deposit metal on the surface and internal fibers of the woven fabric after it has been treated by the pretreatment module 300, thereby obtaining a conductive woven fabric.

The metal chemical deposition chamber 410 is used to contain the metal chemical deposition liquid phase system. The second guide roller group 420 is used to guide the woven fiber fabric to be immersed in the metal chemical deposition liquid phase system and pass through the metal chemical deposition chamber 410. The two second extrusion roller groups 430 are used to extrude the woven fiber fabric before and after entering the metal chemical deposition chamber 410. For example, the immersion time of the woven fiber fabric in the metal chemical deposition liquid phase system is 1 to 10 minutes, the temperature of the metal chemical deposition liquid phase system is 50 to 70°C, and the metal chemically deposited on the woven fiber fabric in the metal chemical deposition liquid phase system can be copper, iron, cobalt, nickel, gold, silver, chromium, manganese, or other metals or alloys.

[0049] Specifically, the second guide roller group 420 includes three second guide rollers arranged in parallel and at intervals along a selected direction. One selected second guide roller located in the middle region is situated inside the metal chemical deposition chamber 410 and immersed in the metal chemical deposition liquid phase system. The other two second guide rollers are located at opposite ends of the metal chemical deposition chamber 410. Specifically, the selected second guide roller located in the middle is movably fitted with the metal chemical deposition chamber 410, and its position in the depth direction of the metal chemical deposition chamber 410 is adjustable. Specifically, to reduce wear between the woven fabric and the second guide rollers during travel, it is preferable that the second guide rollers are rotatable around their own axis. Specifically, the second guide rollers can be directly mounted on the metal chemical deposition container where the metal chemical deposition chamber 410 is located, or a separate second guide support can be provided for mounting the second guide rollers; no specific limitations are made here.

[0050] Specifically, each second extrusion roller group 430 includes two parallel second extrusion rollers. The woven fabric can pass through the roller gap between the second extrusion rollers, and the woven fabric is squeezed during the process of passing through the gap. Through the squeezing of the second extrusion roller group 430, a large amount of moisture inside the woven fabric can be removed and it can be flattened. Specifically, the metal chemical deposition module 400 also includes two second liquid collection chambers 440. Each second liquid collection chamber 440 is correspondingly disposed below a second extrusion roller group 430 and is used at least for collecting the liquid that seeps out through the squeezing of the second extrusion roller group 430. Preferably, the second liquid collection chamber 440 can be integrated with the metal chemical deposition chamber 410 in the same metal chemical deposition container.

[0051] Specifically, in the woven fabric, a small amount of metal particles have been deposited on the surface of each fiber, enhancing the conductivity of the woven fabric. The electrodeposition module 500 is used to electrochemically deposit a metal layer on the surface of the woven fabric and on the fibers within it. For more details, please refer to [link / reference]. Figure 1 and Figure 4 The electrodeposition module 500 includes an electrodeposition chamber 510, two cathode roller groups 520, a titanium basket 530, a third guide roller group 540, and a power supply. The electrodeposition chamber 510 is used to contain the electrolyte. The titanium basket 530 is disposed inside the electrodeposition chamber 510 and is used to contain the positive electrode material. The two cathode roller groups 520 are arranged on both sides of the electrodeposition chamber 510 along a selected direction. The third guide roller group 540 is arranged between the two cathode roller groups 520 along a selected direction. The two cathode roller groups 520 and the third guide roller group 540 together form a guiding structure for guiding the woven fiber fabric to be immersed in the electrolyte and pass through the electrodeposition chamber 510. The cathode roller group 520 is electrically connected to the negative terminal of the power supply. The titanium basket 530 is electrically connected to the positive terminal of the power supply. The two cathode roller groups 520 are also electrically connected to the woven fiber fabric, and the woven fiber fabric is electrically connected to the negative terminal of the power supply. Specifically, the woven fiber fabric immersed in the electrolyte serves as the cathode for metal electrodeposition, connected to the negative terminal of the power supply via the cathode rollers. The titanium basket 530 and the solid metal filling it contains serve as the anode for electrodeposition, connected to the positive terminal of the power supply. Metal cations formed after metal dissolution diffuse into the electrolyte and, under the influence of an electric field, gain electrons on the surface of the woven fiber fabric, completing the metal electrodeposition on the surface of the woven fiber fabric. For example, the current density on the surface of the woven fiber fabric is 0.1–10 A / dm³. 2 The temperature of the electrolyte is 40-60℃. Depending on the metal content requirements of the woven fabric or the production capacity requirements, the number of electrodeposition chambers 510 can be one or more. The metal to be plated in the metallization process can be copper, iron, cobalt, nickel, gold, silver, chromium, manganese and other metals or alloys.

Specifically, after the fiber woven fabric is chemically deposited and electrodeposited, the water washing module 800 can use deionized water to clean the surface and the residual solution from the previous reaction inside.

[0056] To address the problems in the production and processing of metal composite fiber woven fabrics, such as low production efficiency and high cost of metal composite fiber bundles, fiber wear leading to fuzzing during metallization and weaving, poor contact at fiber intersections hindering the formation of a stable and effective conductive network, and complex, costly, and difficult-to-operate processes for metallization of woven fabrics using fiber filaments as a substrate, this invention proposes a continuous metallization preparation device for fiber woven fabrics. This device enables continuous metallization of fiber woven fabrics, reducing frictional damage during high-temperature treatment of single fiber bundles. After high-temperature treatment, the woven fabric undergoes only pretreatment catalytic activation, metal chemical deposition, and metal electrodeposition, achieving metallization and significantly improving production efficiency while reducing costs. Furthermore, compared to metallization processes using vacuum evaporation, ion plating, or magnetron sputtering, this continuous metallization preparation device requires less equipment investment, is simpler and safer to operate, and enables low-cost, continuous, and large-scale production of metal composite fiber woven fabrics.

[0057] This invention provides a continuous metallization preparation device for woven fiber fabrics. The woven fiber fabric is heat-treated and then washed with water to clean its surface. It is then pre-treated to catalytically activate the surface, followed by sequential metal chemical deposition and electrodeposition steps to obtain a metal composite fiber fabric with a non-metallic woven fabric substrate. This device solves the problems mentioned above, such as high production efficiency and low cost of metal composite fiber woven fabrics, fiber damage and fuzzing, poor contact of the fiber conductive network, and complex production processes, high equipment costs, and difficult operation. It achieves continuous, low-cost, and stable roll-to-roll preparation of metal composite fiber woven fabrics.
