Description

Technical Field

[0001] The present application relates to the technical field of electronic device accessories, and more specifically, to a carrier tape for protecting an electronic connector and a preparation method thereof. Background Art

[0002] With the rapid development of technology, the popularity of electronic devices has been continuously increasing globally. As a key component for achieving electrical connection in various electronic devices, electronic connectors have become an indispensable and important part. After the production of electronic connectors, in order to ensure their safe and reliable transportation to various places and put into use, effective packaging and protection measures are usually required. However, the common packaging means currently, such as using materials like EPE blocks or sponge pads to hold the electronic connectors in the placement grooves, although can to a certain extent avoid damage caused by shaking or collision during transportation, these materials themselves have many limitations.

[0003] Firstly, the moisture-proof performance of EPE and ordinary sponge pads is relatively weak. Although EPE itself has certain water-repellent and moisture-proof characteristics, in a high-humidity environment, these materials may still absorb moisture in the air, resulting in the connectors getting damp. The damp connectors may have problems such as decreased insulation performance and oxidation corrosion of metal components, thus affecting their electrical performance and service life.

[0004] Secondly, EPE and ordinary sponge pads do not have anti-static functions. During transportation, these materials may accumulate static electricity due to friction, thereby causing damage to sensitive components in the electronic connectors.

[0005] In addition, the shapes and sizes of EPE and sponge pads are difficult to precisely customize and cannot perfectly fit the shape of the electronic connectors. During packaging, there may be gaps between the materials and the connectors, resulting in instability of the items during transportation, easy shaking, and thus affecting the protection effect. This instability not only increases the risk of damage to the connectors but also may cause loosening of the internal structure of the packaging, further reducing the overall protection performance of the packaging.

[0006] In summary, although EPE and sponge pads have certain advantages in buffer protection, their deficiencies in moisture-proof, anti-static, and customization make it difficult to meet the requirements of high reliability and high protection for electronic connectors during transportation. Therefore, in the future, it is necessary to explore more targeted and comprehensive packaging materials and technologies to further improve the safety and reliability of electronic connectors in the transportation link. Summary of the Invention

[0007] In order to solve the deficiencies of EPE and sponge pads in moisture-proof, anti-static, and customization, the present application provides a carrier tape for protecting an electronic connector and a preparation method thereof.

[0008] In a first aspect, the present application provides a carrier tape for protecting an electronic connector, adopting the following technical solution: A carrier tape for protecting an electronic connector includes a protective disc and a carrier tape. The protective disc includes an upper protective shell and a lower protective shell. The upper protective shell and the lower protective shell are connected by a connecting shaft. The carrier tape is wound around the connecting shaft. The carrier tape is provided with a plurality of placement grooves. Both the protective disc and the carrier tape are obtained by injection molding of ABS masterbatch.

[0009] By adopting the above technical solution, the carrier tape formed by injection molding of ABS masterbatch effectively solves the deficiencies of traditional packaging materials in terms of moisture-proof, anti-static and customization, significantly improves the protection performance and stability of electronic connectors during transportation, reduces the damage risk, and extends the service life. The protective disc and the carrier tape formed by injection molding of ABS masterbatch provide more reliable physical protection for the electronic connector. Through its customized slot design, the carrier tape can closely fit the shape and size of the electronic connector, ensuring that the connector remains stable during transportation and avoiding damage caused by shaking or collision. This fixing method not only reduces the direct impact of external forces on the connector, but also prevents deformation or damage caused by vibration during transportation. In addition, the protective disc and the carrier tape of the carrier tape are connected by a connecting shaft to form an integral structure, which can effectively fix the electronic connector, reduce shaking, and at the same time can carry a large number of electronic connectors. The carrier tape is formed by injection molding of ABS masterbatch and has good waterproof and moisture-proof performance, which can effectively prevent the electronic connector from being affected by moisture in a high-humidity environment. At the same time, the ABS masterbatch can be modified by adding an anti-static agent, thereby endowing the carrier tape with an anti-static function and effectively protecting the electronic connector.

[0010] Preferably, the ABS masterbatch is prepared from the following raw materials in parts by weight: 70 - 80 parts of ABS 30 - 40 parts of talcum powder 10 - 15 parts of polyurethane 3 - 5 parts of compatibilizer 8 - 10 parts of modifier 0.5 - 4 parts of color masterbatch 0.1 - 0.5 parts of anti-static agent The modifier is a core-shell structure toughening agent formed by polybutadiene and acrylonitrile-styrene copolymer; The compatibilizer is composed of acrylonitrile-styrene copolymer grafted maleic anhydride and ethylene-acrylate-glycidyl methacrylate copolymer.

[0011] By adopting the above technical solutions, the impact resistance, abrasion resistance, flexibility and antistatic performance of the protective disc and the carrier tape are improved, meeting the high requirements during the transportation and use of electronic connectors. Among them, ABS as the matrix material provides good mechanical properties and impact resistance for the protective disc and the carrier tape, and its excellent comprehensive properties enable the carrier tape component to meet the basic requirements for protective performance during the transportation of electronic connectors. The addition of talcum powder can significantly improve the rigidity and dimensional stability of the carrier tape component, and enhance the mechanical properties of the material without significantly reducing its toughness. The addition of polyurethane further improves the abrasion resistance and flexibility of the carrier tape component. The synergistic effect of polyurethane and the ABS matrix enables the material to achieve a good balance between high abrasion resistance and high flexibility, which is beneficial to protecting electronic connectors from abrasion, impact and extrusion during transportation.

[0012] The compatibilizer is composed of acrylonitrile-styrene copolymer grafted maleic anhydride and ethylene-acrylate-glycidyl methacrylate copolymer. Its function is to improve the compatibility between ABS and fillers such as talcum powder and polyurethane, and reduce the phase separation phenomenon. The addition of the compatibilizer not only enhances the compatibility of the material, but also improves the fluidity during the processing, and reduces the defects during the molding process.

[0013] The core-shell structure toughener formed by polybutadiene and acrylonitrile-styrene copolymer can significantly improve the impact resistance of the carrier tape component. The polybutadiene core layer provides good flexibility and impact toughness, while the acrylonitrile-styrene copolymer shell layer endows the material with higher mechanical strength and stability. The combination of this core-shell structure toughener and the ABS matrix enables the material to exhibit excellent impact resistance under high stress conditions.

[0014] The addition of the antistatic agent can effectively prevent the electrostatic accumulation generated by friction during the transportation and use of the carrier tape component.

[0015] Preferably, the weight ratio of the acrylonitrile-styrene copolymer grafted maleic anhydride to the ethylene-acrylate-glycidyl methacrylate copolymer is 5:(1 - 3).

[0016] By adopting the above technical solutions and optimizing the weight ratio of the acrylonitrile-styrene copolymer grafted maleic anhydride to the ethylene-acrylate-glycidyl methacrylate copolymer, the advantages of the two graft copolymers can be fully exerted, promoting the compatibility between ABS, polyurethane and talcum powder, thereby significantly improving the impact resistance of the protective disc and the carrier tape.

[0017] Preferably, the modifier is prepared by the following method: 1) Add butadiene into deionized water, add the first emulsifier and the first peroxide initiator, and under stirring conditions, heat the mixture to 60 - 70 °C for emulsion polymerization reaction to form polybutadiene latex; 2) Add acrylonitrile and styrene monomers to the core layer latex, stir, then add the second emulsifier, crosslinking agent and second peroxide initiator, and continue to react at 60 - 70 °C for 2 - 4 hours. Separate the core-shell structured particles by centrifugation or filtration, and wash the particles with deionized water to obtain the modifier.

[0018] By first preparing polybutadiene latex as the core layer and then grafting acrylonitrile-styrene copolymer on its surface to form the shell layer, a core-shell structure is successfully constructed, which can significantly improve the impact resistance and flexibility of the material, enabling the carrier tape to better withstand external forces during transportation and protecting the electronic connector from damage. Step 1) can evenly disperse butadiene monomers in deionized water to form a stable latex, which helps the uniform formation of the core layer and further improves the performance of the core-shell structure. In step 2), an acrylonitrile-styrene copolymer shell layer can be formed on the surface of the polybutadiene core layer, and the formed polybutadiene and acrylonitrile-styrene copolymer are of uniform size.

[0019] Preferably, the parts by weight of the raw materials used to prepare the modifier are as follows: 20 - 35 parts of butadiene 200 - 300 parts of deionized water 5 - 10 parts of the first emulsifier 0.5 - 1 part of the first peroxide initiator 30 - 40 parts of acrylonitrile 10 - 15 parts of styrene monomer 6 - 10 parts of the second emulsifier 1 - 2 parts of the crosslinking agent 0.2 - 0.8 part of the second peroxide initiator.

[0020] By adopting the above technical solution, optimizing the weight of the raw materials used in the modifier is beneficial to the full progress of the reaction to form a core-shell structure. The core-shell structure can effectively disperse stress and reduce stress concentration points, thereby improving the toughness and strength of the protective disc and the carrier tape.

[0021] Preferably, both the first emulsifier and the second emulsifier include at least one of oleic acid, linoleic acid, disproportionated rosin acid, stearic acid, and sodium dodecylbenzenesulfonate.

[0022] By adopting the above technical solution, it can effectively reduce the interfacial tension between the aqueous phase and the oil phase, promote the uniform dispersion of butadiene monomers in deionized water, and thus improve the efficiency of emulsion polymerization. At the same time, the stable emulsion formed by the emulsifier during the emulsion polymerization process helps to form a uniform core-shell structure, thereby improving the mechanical properties of the final product.

[0023] Preferably, the crosslinking agent is divinylbenzene or ethylene glycol dimethacrylate.

[0024] By adopting the above technical solution, the type of cross-linking agent is optimized, so that a three-dimensional network structure is formed during the shell polymerization process, significantly improving the mechanical strength of the protective disc and the carrier tape, and effectively preventing the deformation and cracking of the protective disc and the carrier tape under high stress conditions.

[0025] Preferably, the mesh number of the talcum powder is 200 mesh - 800 mesh.

[0026] By adopting the above technical solution, the mesh number of the talcum powder is optimized. The addition of talcum powder can significantly improve the rigidity and dimensional stability of the protective disc and the carrier tape. The smaller the particle size of the talcum powder, the larger its specific surface area, the more contact points with the polymer matrix, and the more evenly it can transfer stress, thereby improving the impact resistance of the material. The talcum powder with a mesh number of 200 mesh - 800 mesh has a moderate particle size, can effectively improve the rigidity and impact resistance without significantly reducing the toughness of the material. At the same time, the talcum powder with a mesh number of 200 mesh - 800 mesh has good dispersibility and can be evenly distributed in the ABS matrix, thereby improving the processing performance of the material.

[0027] Preferably, the antistatic agent includes one or more of glycerol monostearate, diethanolammonium alkyl phosphate, and ethoxyalkylamine.

[0028] By using the above antistatic agent, the risk of static electricity accumulation of the protective disc and the carrier tape can be significantly reduced, thereby reducing the damage of static electricity to the electronic connector.

[0029] In a first aspect, the present application provides a preparation method for a carrier tape member for protecting an electronic connector, adopting the following technical solution: A preparation method for a carrier tape member for protecting an electronic connector includes the following steps: S1. Mix ABS, talcum powder, polyurethane, compatibilizer, modifier, masterbatch, and antistatic agent to obtain an ABS masterbatch; S2. Inject the ABS masterbatch to form a protective disc; S3. Inject the ABS masterbatch to form a carrier tape; S4. Wind the carrier tape around the protective disc to obtain a carrier tape member for protecting an electronic connector.

[0030] By separately molding the protective disc and the carrier tape through the injection molding process, high-precision and high-efficiency production can be achieved. Injection molding ensures the dimensional accuracy and surface quality of the carrier tape parts, meeting the strict requirements of electronic connectors for packaging. The high degree of automation in injection molding enables the rapid production of a large number of high-quality carrier tape parts to meet the needs of mass production. Through its structural design and material properties, the carrier tape part provides comprehensive protection for electronic connectors. It can not only prevent physical impact and electrostatic damage but also prevent the erosion of moisture and dust, ensuring the reliability of electronic connectors during transportation and use.

[0031] In summary, the present application has the following beneficial effects: 1. By winding the carrier tape around the protective disc to form an integral structure, the present application can effectively fix the electronic connector and reduce shaking and collision during transportation. This structural design not only improves the stability of the carrier tape part but also enhances its protection ability for the electronic connector. The structural design of the carrier tape part can effectively isolate dust and moisture in the external environment, protect the electronic connector from the influence of a humid environment, and ensure that its electrical performance is not damaged during transportation and storage. 2. By mixing ABS, talcum powder, polyurethane, compatibilizer, modifier, masterbatch, and antistatic agent, the prepared ABS masterbatch has excellent comprehensive properties. Talcum powder enhances the rigidity and dimensional stability of the material; polyurethane improves wear resistance and flexibility; the modifier significantly improves the impact resistance performance; the compatibilizer improves the compatibility between components; the antistatic agent endows the material with antistatic function. The synergistic effect of these components makes the carrier tape part perform excellently in protecting electronic connectors. Description of the Drawings

[0055] Testing method / Experimental method Stability test: Place the carrier tapes for protecting electronic connectors prepared in Examples 1-6 and Comparative Examples 1-5 on a horizontal plane, and place iron cakes with the same surface area as their surfaces (each iron cake has a mass of 500 g) on their surfaces. Successively increase the number of iron cakes until cracks appear in the protective disc or the carrier tape, and record how many iron cakes there are.

[0056] Impact resistance test: Drop the carrier tapes for protecting electronic connectors prepared in Examples 1-6 and Comparative Examples 1-5 freely from a height of 3 m above the horizontal cement floor, and observe whether cracks appear in the protective disc or the carrier tape.

[0057] Shockproof test: Place glass beads in the placement grooves of the carrier tape (each carrier tape has 100 placement grooves), and seal it with sealing film. Then wind the carrier tape with glass beads around the protective disc, wrap a layer of protective film on the surface of the protective disc, and place it on a vibration table. Set the vibration frequency range to 35 Hz, the acceleration amplitude to 0.5 g, and stop for 30 s after 180 s of continuous vibration. Then repeat the experiment 10 times, and count the number of cracked or broken glass beads. The experimental data are shown in Table 3: Table 3 Experimental data of Examples 1-6 and Comparative Examples 1-5 Comparing Example 1 with Comparative Examples 1-2, the number of iron cakes that Comparative Examples 1-2 can withstand in the stability test is less than that of Example 1, and the number of broken glass beads in Comparative Examples 1-2 in the shockproof test is greater than the number of broken ones in Example 1.
