Description

線材之製程 Wire manufacturing process

本發明為提供一種線材之製程，尤指一種有效將記形材料定型為預定造型，並提供記形材料良好的彈性及高度恢復力的線材之製程。 The invention provides a process for the wire material, in particular to a wire rod which is effective for shaping the shape material into a predetermined shape and providing the wire material with good elasticity and high restoring force.

按，在電容器披覆用途等方面所使用的電氣絕緣材料，主要係廣泛的使用由氯化乙烯所構成的熱收縮性套管，但是，聚氯化乙烯製成的熱收縮性套管存在有燃燒時會產出氯化氫氣體的問題，以及在焚化等廢棄處理之際，有容易損害焚化爐等問題點，從此觀點出發，遂改用聚酯樹脂製之熱收縮性套管來取代聚氯化乙烯製之套管。此外，近年來在電容器等電子組件方面，因製品的輕薄短小化而高密度化，故要求可承受電子組件散熱的耐熱性，因而對聚酯樹脂製熱收縮性套管仍要求具有良好的耐熱性。 According to the electrical insulating materials used in the application of capacitors, the heat-shrinkable sleeve made of vinyl chloride is widely used, but the heat-shrinkable sleeve made of polyvinyl chloride exists. The problem of hydrogen chloride gas is produced during combustion, and problems such as incinerators are easily damaged at the time of disposal such as incineration. From this point of view, tampering with a heat-shrinkable sleeve made of polyester resin instead of polychlorination A casing made of vinyl. In addition, in recent years, in terms of electronic components such as capacitors, the density of the products is reduced and the density is increased. Therefore, it is required to withstand the heat resistance of the heat dissipation of the electronic components. Therefore, the heat-shrinkable sleeve made of the polyester resin is required to have good heat resistance. Sex.

當使用於鋁電解電容器披覆用的情況時，熱收縮性聚酯系套管在高溫高濕下的耐久性尚嫌不足。例如，汽車的電裝組件等乃使用於酯熱的車體內或引擎室周圍，因而要求高度的耐熱性。再者，因為直接受到因風吹雨淋等天候影響、氣候變動而發生結露等影響，因而在要求耐熱性之同時，亦要求相對應的耐濕性。在此種使用條件下，將熱收縮性聚酯系套管披覆的電容器，長期放置於高溫高濕下的話，則有迅速變脆弱，而最終將發生龜裂、破裂、脫落等情況，喪失電容器的絕緣性而導致短路情況，以及無法辨識印刷於套管表面供辨識電容器極性用之資訊等問題點。 When used for the coating of an aluminum electrolytic capacitor, the durability of the heat-shrinkable polyester sleeve under high temperature and high humidity is insufficient. For example, an electric component of an automobile or the like is used in an ester-heated vehicle body or around an engine room, and thus requires high heat resistance. In addition, since it is directly affected by weathering such as wind and rain, climate change, and condensation, it is required to have heat resistance and moisture resistance. Under such conditions of use, when a capacitor coated with a heat-shrinkable polyester sleeve is placed under high temperature and high humidity for a long period of time, it will rapidly become brittle, and eventually cracks, cracks, shedding, etc. will be lost. The insulation of the capacitor causes a short circuit condition, and the problem of printing on the surface of the sleeve for identifying the polarity of the capacitor is not recognized.

藉由上述之說明，已可了解本技術之結構，而依據這個結構之對應配合，更可有效將記形材料1定型為預定造型，並提供記形材料1良好的彈性及高度恢復力等優勢，而詳細之解說將於下述說明。 Through the above description, the structure of the present technology can be understood, and according to the corresponding cooperation of the structure, the shape material 1 can be effectively shaped into a predetermined shape, and the advantages of good elasticity and high restoring force of the shape material 1 are provided. The detailed explanation will be explained below.

本實施例所選用之記形材料1係為聚氨酯(Polyurethane，PU)或熱塑性聚胺基甲酸酯(Thermoplastic Polyurethane，TPU)，就產品型態而言，聚氨酯產品大致可以分：PU發泡(軟質或硬質)、PU塗料、PU黏著劑、PU合成皮革、PU跑道、PU彈性體，類似這些早已廣泛使用於人們日常生活中。而TPU分子基本上是線型的，是一種環保材質、不含可塑劑，也是一種高分子彈性體，其彈性介於橡膠與塑膠之間，而擁有最佳物性，且具有耐衝擊、耐曲折、高延伸性、高抗撕裂強度、耐低溫特性等特性。 The shape material 1 selected in this embodiment is Polyurethane (PU) or Thermoplastic Polyurethane (TPU). In terms of product type, the polyurethane product can be roughly divided into: PU foam ( Soft or hard), PU coatings, PU adhesives, PU synthetic leather, PU runways, PU elastomers, etc., have long been widely used in people's daily lives. The TPU molecule is basically linear, is an environmentally friendly material, does not contain a plasticizer, and is also a polymer elastomer. Its elasticity is between rubber and plastic, and it has the best physical properties, and has impact resistance and tortuosity. High elongation, high tear strength, low temperature resistance and other characteristics.

然而，上述特性係針對市場現有之產品而言，但以目前之製程手段所產製之記形材料1，其物性已無法滿足現代之消費者，其因在於對收納時的體積需求更高、對產品之衝擊曲折的耐受力與時間長度更要求，同時欲維持原有之記憶外形的特色而要求具有高恢復力。因此，申請人特以上述步驟製造線材。 However, the above characteristics are for the existing products in the market, but the physical properties of the biometric material 1 produced by the current process means cannot satisfy the modern consumers, because the volume demand for storage is higher. It is more demanding on the tortuosity of the product and the length of time, and it is required to maintain the original memory shape and requires high resilience. Therefore, the applicant has specially manufactured the wire in the above steps.

又以本實施例之耳機線為記形材料1之塑型目標，將適當長度(400mm至410mm)之記形材料1包膜21成線扎2(如第三圖所示)後，捲繞於定型載具3上，該定型載具3上可設置複數限位件(如螺絲釘)，以對記形材料1之外型輪廓做 限位，之後於線扎2兩端固定以固定件4，而將記形材料1暫時定型成C形材料11(如第四圖所示)。接著即可連同定型載具3將線扎2置入烤箱51，以175度~185度之溫度烘烤15分鐘~25分鐘，藉此對記形材料1進行塑型及定型(如第五圖所示)，烘烤完成後，隨即取出線扎2置入冷水中12秒~18秒，迅速將線扎2表面降溫(如第六圖所示)，再以牛角風扇52對線扎2進行風冷乾燥7分鐘~13分鐘，避免記形材料1因吸濕性造成表面的水花紋或起泡現象(如第七圖所示)。最後對記形材料1的外觀、尺寸進行檢視、丈量等品質確認。品質標準如下：該C形材料11兩端間界定有一開口間距D，該開口間距D小於55釐米(mm)、該C形材料11兩內側壁間界定有一最大內徑R，該最大內徑R為11公分至13公分、該C形材料11之弧頂與開口間界定有一最大長度L，該最大長度L小於15公分。 Further, the earphone wire of the embodiment is a molding target of the shape material 1, and the film 21 of the appropriate length (400 mm to 410 mm) is wrapped into a wire 2 (as shown in the third figure), and then wound. On the shaping carrier 3, the fixing carrier 3 can be provided with a plurality of limiting members (such as screws) to make a contour on the shape of the material 1 After the limit, the fixing member 4 is fixed to both ends of the wire 2, and the material 1 is temporarily shaped into a C-shaped material 11 (as shown in the fourth figure). Then, the wire tie 2 can be placed in the oven 51 together with the shaping carrier 3, and baked at a temperature of 175 to 185 degrees for 15 minutes to 25 minutes, thereby shaping and shaping the shape material 1 (such as the fifth figure). As shown), after the baking is completed, the wire 2 is taken out and placed in cold water for 12 seconds to 18 seconds, and the surface of the wire 2 is quickly cooled (as shown in the sixth figure), and then the wire horn 2 is performed by the horn fan 52. Air-cooled and dried for 7 minutes to 13 minutes to avoid the water pattern or blistering of the surface of the material 1 due to hygroscopicity (as shown in Figure 7). Finally, the appearance and size of the material 1 are examined and measured. The quality standard is as follows: the C-shaped material 11 defines an opening spacing D between the two ends, the opening spacing D is less than 55 centimeters (mm), and the inner diameter of the C-shaped material 11 defines a maximum inner diameter R, the maximum inner diameter R Between 11 cm and 13 cm, a maximum length L is defined between the arc top and the opening of the C-shaped material 11, and the maximum length L is less than 15 cm.
