Description of the Invention [Technical Field of the Invention] The present invention relates to a sprocket mounting edge for inserting a slider into a waterproof chain of a woven or braided ribbon core covered with a waterproof layer. The water-repellent zipper of one of the plurality of synthetic resin-made sprocket teeth is integrated and arranged to be attached to the chain rack. [Prior Art] In the case of such a waterproof zipper, a pair of left and right chain belts are provided, each of which is a belt body woven or braided by a fiber yarn, or a belt-shaped non-woven fabric as a core material. The back of the material is covered with a waterproof layer composed of an elastomer. Further, a pair of opposite side edge portions of the pair of chain belts are used as the sprocket mounting edge portions, and the synthetic resin sprocket is implemented along the fastener element mounting edge portion so as to straddle both the front and back sides of the fastener tape. The injection molding is performed by injection molding or the like to form a chain rack. Further, in the chain of the chain of the chain, the sliders of the left and right teeth are engaged and disengaged. In general, in the waterproof zipper, the rim portion of the fastener tape is provided with a through hole penetrating through the front and back surfaces of the fastener tape in advance at the molding portion of each fastener element, and the component forming portion having the through hole is formed. The injection molding of the synthetic resin is carried out so that the through-holes serve as a passage for the synthetic resin, and the ribs are sandwiched between the fastener elements so as to form a symmetrical shape on both the front and back sides of the fastener tape. Further, each of the fastener elements is connected to the lower half of the upper half and the lower half of the component on the surface side of the formed fastener by the connecting portion penetrating the through hole, thereby improving the joint strength of the fastener tape and the fastener element. . -4- (2) (2), 1306744 An example of a conventional waterproof zipper having the above-described configuration is disclosed in Japanese Patent Publication No. Sho 63-300247 (Patent Document 1) and Japanese Patent Laid-Open No. 2005-23 75 77 Bulletin (Patent Document 2) and the like are described. For example, the waterproof slide fastener described in Patent Document 1 is formed by forming a waterproof layer on the front and back surfaces of the fastener tape, and forming a through hole in the fastener element edge portion of the fastener tape. Further, the upper half of the sprocket is formed on the front and back surfaces of the sprocket attachment edge portion, and the upper and lower portions of the coupling portion of the through hole through which the rim portion is attached are integrated. Further, in the waterproof zipper of Patent Document 1, an adhesive layer is formed on at least the front and back surfaces of the fastener tape corresponding to at least the periphery of the through hole, and the adhesive layer is used to seal the contact zone between the fastener tape and the fastener element around the through hole. And make the boundary department watertight. On the other hand, the above-mentioned Patent Document 2 describes a waterproof zipper having a characteristic of a sprocket shape. Each of the fastener elements of one of the water-repellent zippers described in Patent Document 2 has an engaging head portion, a neck portion, a crotch portion, and a crotch portion toward the chain portion which are formed by integrally forming the upper lower half portion on the back surface of the chain belt surface. The upper and lower half portions of the leg portion are integrally connected by a connecting portion formed by a through hole formed in the edge portion of the element attaching portion. Further, the engaging head portion and the respective half portions of each of the fastener elements are formed such that the thickness in the direction perpendicular to the back surface of the fastener tape is thinner than the respective half portions of the neck portion and the crotch portion. Further, the upper and lower portions of the foot are used to slidably guide the upper and lower flanges of the slider, and are disposed in the sliding direction of the slider at a predetermined interval by two or more. The water-repellent zipper of Patent Document 2 in which the sprocket of the above-described shape is formed in the sprocket mounting edge portion is provided with two or more upper and lower portions of the foot for performing the sliding guide of the slider in the sliding direction. In the sliding operation of the slider -5 (3), 1306744, the sliding resistance can be reduced, and the sliding operation of the slider is lighter. In addition, when performing the injection molding of the sprocket, the chain is formed by pressing the mold surface from the front and back sides of the half-forming cavity for the foot, and the chain is not swayed during the molding. The part is strongly fused to the back of the chain and integrated. Thereby, there is an advantage of enhancing the fixing strength of the sprocket to the chain. [Patent Document 1] Japanese Patent Publication No. 2005-237577 (Patent Document 2) Japanese Laid-Open Patent Publication No. 2005-237577 (Patent Document 1) discloses that the waterproof zipper chain is made of fiber. The belt body woven or braided is used as a core material, and the front and back sides of the belt-shaped core material are covered with a waterproof layer, and the waterproof layer is made of an elastomer such as natural rubber or synthetic rubber. However, these Patent Documents 1 and 2 only briefly describe materials that can be used as a waterproof layer. At present, most of the commercially available waterproof zippers generally use the above-mentioned waterproof layer with excellent strength. A thermoplastic polyester elastomer (specifically, HYTREL (registered trademark)) such as durability and moldability. Further, as a material of the fastener element formed in the fastener tape, HYTREL (registered trademark) of a polybutylene terephthalate having good adhesion and durability is used. On the other hand, in recent years, as the use of the waterproof zipper has become more widespread, the waterproof zipper has become more and more diverse, and it is required to improve the adhesion of the object to the waterproof zipper.

之物，仍然有對聚胺甲酸乙酯系之被著物的接著性不良之 一面。因此，形成著由熱塑性聚酯彈性體所構成之防水層 之鏈帶’有與聚胺甲酸乙酯系之素材或覆蓋著胺甲酸乙酯 被覆之素材的接著性較差之問題。尤其是，將防水層由聚 酯彈性體所形成之防水性拉鏈裝設於例如聚胺甲酸乙酯系 之被著物時，不會採用通常所使用之高頻熔接，而必須採 用縫製或接著劑，故無法避免麻煩之作業。 φ 此外，聚酯彈性體以彈性體而言，具有缺乏彎曲性之 一面。因此，覆蓋著聚酯彈性體之鏈帶，會呈現較硬的傾 向，例如，有使鏈帶朝表背面進行U字形之彎曲、扭轉時 之彎曲性較低之問題。因此，將防水層由聚酯彈性體所形 成之防水性拉鏈，裝設於例如潛水衣等之被著物時，因爲 防水性拉鏈之裝設部份會變硬，故將該被著物穿著於身上 或脫除時，會覺得很辛苦，此外，也會降低其穿著舒適感 〇 φ 此外，爲了提高聚胺甲酸乙酯系之被著物之接著性， 形成於鏈帶之防水層，應使例如比聚酯彈性體更易接著且 更柔軟之聚胺甲酸乙酯彈性體的聚胺甲酸乙酯系被著物。 然而，只是單純利用聚胺甲酸乙酯彈性體來形成鏈帶之防 水層時，聚丁烯對苯二甲酸酯製之鏈齒之接著性則會大幅 降低。 因此，即使利用貫通前述鏈齒裝設緣部之貫通孔的連 結部來以連結一體化之方式來形成各鏈齒之上下半部的鏈 帶，鏈帶及鏈齒之固著強度也必然會降低’因而降低防水 -7 - (5) 1306744 性拉鏈之嚙合強度及水密性，此外，鏈齒會以連結部爲中 心進行轉動’而發生左右之鏈齒列無法嚙合之問題。 ./ <有鑑於上述傳統之課題，本發明之具體目的在於提供 ，鏈帶與胺甲酸乙酯等之被著物之接著性優良且彎曲性良 好，且鏈帶及鏈齒之間具有高固著強度且具有優異嚙合強 度及水密性之防水性拉鏈。 爲了達成上述目的，本發明提供之防水性拉鏈之基本 構成，係具備：沿著覆蓋著防水層之由織物、編物、或不 織布所構成之帶狀芯材之一對防水性鏈帶之相對向之鏈齒 裝設緣部排列設置著成形一體化之複數之鏈齒之一對鏈布 齒條；及可使前述鏈齒嚙合脫離之拉頭；之防水構造的拉 鏈，其最主要之特徵爲，前述防水層係由聚胺甲酸乙酯彈 性體所構成，前述鏈齒係由聚胺甲酸乙酯樹脂及ABS樹 脂之高分子合金所構成。 此外，本發明之防水性拉鏈之前述高分子合金的前述 聚胺甲酸乙酯樹脂及前述ABS樹脂之比例（聚胺甲酸乙酯 樹脂/ ABS樹脂）係重量比爲20/8 0〜50/50。 本發明之防水性拉鏈係具有覆蓋著帶狀芯材由聚胺甲 酸乙酯彈性體所構成之防水層的鏈帶，該鏈帶裝設著成形 一體化之由聚胺甲酸乙酯樹脂及ABS樹脂之高分子合金 所構成之複數之鏈齒。 本發明者等爲了使覆蓋著防水層之鏈帶與胺甲酸乙酯 被覆等之被著物之接著性高於傳統，防水層之材質並非使 用傳統上一般所使用之聚酯彈性體（例如，HYTREL)，並 (6) 1306744 針對使用聚胺甲酸乙酯彈性體時進行檢討。然而，以聚胺 甲酸乙酯彈性體形成防水層時，如前面所述，有與聚丁烯 對苯二甲酸酯製之鏈齒之接著性較低的問題。因此，鏈齒 之材質，不使用傳統一般的聚丁烯對苯二甲酸酯，而使用 與聚胺甲酸乙酯彈性體之互適性（親和性）良好且具有優異 接著性之新合成樹脂，並進行審慎地實驗及檢討。 首先，鏈齒之材質，考慮與防水層之聚胺甲酸乙酯彈 性體的親和性及接著性，針對單獨採用聚胺甲酸乙酯樹脂 進行檢討。然而，只以聚胺甲酸乙酯樹脂形成鏈齒時，雖 然可以提高與聚胺甲酸乙酯彈性體之接著性，然而，實施 鏈齒之成形時，至樹脂之冷卻固化爲止需要花費較多時間 ，有難以切離澆口且成形性較差之問題。此外，以聚胺甲 酸乙酯樹脂所形成之鏈齒非常柔軟，元件之剛性不足，而 有實用性不足的問題。此外，鏈齒之材質除了聚胺甲酸乙 酯樹脂以外，亦可使用ABS樹脂及聚碳酸酯樹脂，然而 ，單獨使用該等樹脂材料時，有不易得到元件之強度且抗 化學性較差之缺點。 其次，爲了解決鏈齒之材質採用聚胺甲酸乙酯樹脂時 之上述問題，針對其材質進一步進行實驗及檢討，結果， 發現ABS樹脂與聚胺甲酸乙酯樹脂具有良好之互適性且 具有優異之成形性，故使用聚胺甲酸乙酯樹脂及ABS樹 脂之高分子合金做爲鏈齒之材質，除了可改善鏈齒之成形 性以外，也可提高鏈齒之剛性，而完成本發明。 亦即，形成於鏈帶之防水層係由聚胺甲酸乙酯彈性體 -9- (7) 1306744 所構成’此外，成形一體化於鏈帶之 乙酯樹脂及ABS樹脂之高分子合金 時，可以活用各材料之特徵，鏈帶與 被著物具有優良接著性且耐摩耗性優 形性及剛性也良好，此外，鏈帶及鏈 較高。 因此’因爲本發明之防水性拉鏈 甲酸乙酯彈性體覆蓋於鏈帶之表面， 之合成樹脂所製作被著物具有優良接 合此種聚胺甲酸乙酯系之被著物。此 拉鏈具有優良之鏈帶彎曲性、耐摩耗 水密性。 此外’爲了提高防水性拉鏈之機 之高分子合金之前述聚胺甲酸乙酯樹 之比例進行檢討。結果，本發明之防 乙酯樹脂及AB S樹脂之比例（聚胺甲| )之重量比爲20/80〜50/50時，可進 性 '強度、以及剛性，而爲拉鏈之橫 之高品質之防水性拉鏈。 【實施方式】 以下，參照圖面，針對本發明之 目羊細說明。此外，本發明並未受限於 ’只要具有與本發明爲實質相同之構 鏈齒，係由聚胺甲酸 所構成之防水性拉鏈 胺甲酸乙酯被覆等之 異，此外，鏈齒之成 齒之間之固著強度也 很容易成形而將聚胺 與由聚胺甲酸乙酯系 著性，尤其是特別適 外，本發明之防水性 性、嚙合強度、以及 能，也針對構成鏈齒 脂及前述ABS樹脂 水性拉鏈之聚胺甲酸 隻乙酯樹脂/ABS樹脂 一步提升鏈齒之成形 拉強度等也十分優異 良好實施形態，進行 以下說明之實施形態 成，且，具有相同作 -10- (8) 1306744 用效果，可以實施多樣化變更。例如，本發明之鏈齒之形 狀及尺寸等並未受限於下述之實施形態，必要時，可進行 適度變更。 第1圖係本實施形態之防水性拉鏈之部份平面圖，第 2圖係該拉鏈所具有之鏈齒的放大平面圖。此外，第3圖 係沿著第1圖之III-III線之箭頭方向剖面圖。 本實施形態之防水性拉鏈1係具備：沿著配設於具有 防水性之鏈帶1 〇之一側緣部之鏈齒裝設緣部1 1，以具有 與相對向之鏈齒21之嚙合間隔排列設置著成形一體化之 複數個鏈齒21之鏈布齒條2;省略圖示之可使左右之鏈齒 21嚙合脫離之合成樹脂製或金屬製之拉頭；以及省略圖示 之上擋具及開離嵌插具。 前述鏈帶1 〇之由纖維絲條之織物、編物、或不織布 所構成之帶狀之芯材12之表背全部表面覆蓋著由聚胺甲 酸乙酯彈性體所構成之防水層13。此種鏈帶10;被聚胺甲 酸乙酯彈性體所覆蓋’不但可確保防水性，且很容易以高 頻熔接裝設於聚胺甲酸乙酯系及胺甲酸乙酯被覆之被著物 。此外’與例如覆蓋著聚酯彈性體之鏈帶相比，鏈帶本身 較爲柔軟，而具有良好彎曲性。此外，於該鏈帶10之上 述鏈齒裝設緣部1 1之各元件成形部位，分別形成可分別 供鏈齒21之熔融狀態之原料樹脂通過之具有足夠大小之 貫通孔1 4。 前述鏈齒21係由：呈長圓形狀之嚙合頭部22;介由 頸部23連結於該嚙合頭部22之略呈六角形狀之胴部24 ;

Therefore, the chain tape ' formed of the waterproof layer composed of the thermoplastic polyester elastomer has a problem of poor adhesion to the polyurethane-based material or the urethane-coated material. In particular, when a water-repellent zipper formed of a polyester elastomer is attached to a polyurethane-based urethane, for example, a high-frequency welding which is generally used is not used, and sewing or subsequent splicing must be employed. Agent, it is impossible to avoid troublesome work. φ In addition, the polyester elastomer has a side lacking in flexibility as an elastomer. Therefore, the fastener tape covered with the polyester elastomer exhibits a harder inclination, for example, there is a problem that the chain belt is bent in a U-shape toward the front and back surfaces, and the bending property at the time of twisting is low. Therefore, when the water-repellent zipper formed of the polyester elastic body is attached to a subject such as a wetsuit, the wearable portion of the waterproof zipper is hardened, so that the object is worn. It will be very hard when it is removed from the body or removed. In addition, it will also reduce the wearing comfort. In addition, in order to improve the adhesion of the polyurethane-based object, it should be formed on the waterproof layer of the chain. A polyurethane-based coating of a polyurethane elastomer which is, for example, easier and more flexible than a polyester elastomer. However, when the polyurethane layer elastomer is used alone to form the water-repellent layer of the chain, the adhesion of the chains of the polybutylene terephthalate is greatly reduced. Therefore, even if the chain portion of the lower half of each element is formed by the connection portion penetrating through the through hole of the sprocket attachment edge portion, the anchoring strength of the chain belt and the sprocket are inevitably Lowering 'and thus reducing the meshing strength and watertightness of the waterproof -7 - (5) 1306744 zipper, and the sprocket will rotate around the joint portion', and the left and right sprocket rows cannot be engaged. In view of the above-mentioned conventional problems, a specific object of the present invention is to provide a fastener having excellent adhesion to a substrate such as urethane and a good bendability, and a high chain and a sprocket. Waterproof zipper with strong anchor strength and excellent meshing strength and water tightness. In order to achieve the above object, the basic structure of the waterproof zipper provided by the present invention has a relative orientation of one of the strip-shaped core materials composed of a woven fabric, a knitted fabric, or a non-woven fabric covering the waterproof layer to the waterproof chain. The chain tooth mounting edge is arranged with one of a plurality of stitches forming a plurality of stitches, and a slider which can disengage the aforementioned fastener teeth; the main feature of the waterproof structure zipper is The water repellent layer is composed of a polyurethane elastomer, and the sprocket system is composed of a polyurethane alloy and a polymer alloy of ABS resin. Further, the ratio of the polyurethane resin to the ABS resin (polyurethane resin/ABS resin) of the polymer alloy of the water-repellent zipper of the present invention is 20/8 0 to 50/50. . The waterproof zipper of the present invention has a chain covering a waterproof layer composed of a polyurethane core of a belt-shaped core material, and the chain belt is integrally formed of polyurethane resin and ABS. A plurality of fastener elements composed of a polymer alloy of a resin. The inventors of the present invention have higher adhesiveness than the conventionally used polyester elastomer in order to make the adhesive tape of the waterproofing layer covered with the urethane coating or the like higher than the conventional one (for example, HYTREL), and (6) 1306744 Review for the use of polyurethane elastomers. However, when the water repellent layer is formed of a polyurethane elastomer, as described above, there is a problem that the adhesion to the sprocket of the polybutylene terephthalate is low. Therefore, the material of the fastener element does not use the conventional general polybutylene terephthalate, but uses a new synthetic resin which is excellent in compatibility (affinity) with the polyurethane elastomer and has excellent adhesion. And conduct prudent experiments and reviews. First, the material of the fastener element is considered for the affinity and adhesion of the polyurethane elastomer of the water repellent layer, and the polyurethane resin alone is used for review. However, when the fastener element is formed only of the polyurethane resin, the adhesion to the polyurethane elastomer can be improved. However, when the fastener element is formed, it takes a long time until the resin is cooled and solidified. There is a problem that it is difficult to cut off the gate and the formability is poor. Further, the sprocket formed of the polyurethane resin is very soft, and the rigidity of the element is insufficient, which has a problem of insufficient practicality. Further, the material of the fastener element may be an ABS resin or a polycarbonate resin in addition to the polyurethane resin. However, when these resin materials are used alone, the strength of the element is not easily obtained and the chemical resistance is inferior. Next, in order to solve the above problems in the case of using a polyurethane resin in the material of the fastener element, further experiments and reviews were conducted on the material, and as a result, it was found that the ABS resin and the polyurethane resin have good compatibility and are excellent. Since the formability is used, the polymer alloy of the polyurethane resin and the ABS resin is used as the material of the fastener element, and the rigidity of the fastener element can be improved in addition to the moldability of the fastener element, and the present invention has been completed. That is, the water-repellent layer formed on the fastener tape is composed of polyurethane elastomer-9-(7) 1306744', and when it is formed into a polymer alloy of a chain resin and a polymer alloy of ABS resin, The characteristics of each material can be utilized, the chain tape and the object have excellent adhesion, and the wear resistance is excellent, and the rigidity is also good. Further, the chain and the chain are high. Therefore, since the water-repellent zipper formic acid elastomer of the present invention covers the surface of the fastener tape, the synthetic resin-made object has an excellent adhesion to the polyurethane-based object. This zipper has excellent chain bending, abrasion resistance and water tightness. In addition, the ratio of the aforementioned polyurethane resin of the polymer alloy for improving the waterproof zipper is reviewed. As a result, when the weight ratio of the ratio of the ethyl ester resistant resin and the AB S resin (polyamine A) of the present invention is 20/80 to 50/50, the advanceability 'strength, and rigidity, and the zipper height are high. Waterproof zipper for quality. [Embodiment] Hereinafter, the present invention will be described in detail with reference to the drawings. Further, the present invention is not limited to the 'as long as it has substantially the same structure as the present invention, and is a water-repellent zipper urethane coated with polyurethane, and the like. The fixing strength between the two is also easy to form, and the polyamine is made of polyurethane, especially especially suitable. The water repellency, the meshing strength, and the energy of the present invention are also aimed at constituting the sprout And the ABS resin water-based zipper of the polyurethane-only ethyl ester resin/ABS resin is also excellent in the form-forming tensile strength of the one-step-up fastener element, and the embodiment described below is carried out, and has the same operation -10- ( 8) 1306744 With the effect, diversified changes can be implemented. For example, the shape and size of the fastener element of the present invention are not limited to the following embodiments, and may be appropriately changed if necessary.

The surface of the front and back of the strip-shaped core material 12 composed of the woven fabric, the knitted fabric or the non-woven fabric of the above-mentioned fastener tape 1 is covered with a waterproof layer 13 composed of a polyurethane elastomer. Such a fastener tape 10; covered with a polyurethane elastomer is not only capable of ensuring water repellency, but also is easily attached to a polyurethane-coated or urethane-coated substrate by high-frequency welding. Further, the fastener tape itself is softer than the fastener tape covered with the polyester elastomer, and has good flexibility. Further, in each of the element forming portions of the fastener tape mounting edge portion 1 1 on the fastener tape 10, through holes 14 having a sufficient size to allow the raw material resins in the molten state of the fastener elements 21 to pass therethrough, respectively, are formed. The sprocket 21 is composed of an oblong meshing head portion 22; a slightly hexagonal ridge portion 24 connected to the engaging head portion 22 via a neck portion 23; -11 - 1306744 Ο) spanning the aforementioned neck portion 23 and The wing-shaped shoulder portion 25 extending between the crotch portion 24 and extending to the left and right; and the lower end portion of the crotch portion 24 are branched from the thigh portion 26 into two legs 27 extending downward. The sprocket 21 having the above configuration has a lower half portion of the element attaching edge portion 11 that sandwiches the chain belt 10, and the upper and lower halves are connected and integrated via the connecting portion 28 formed in the through hole 14. . The engaging head portion 22, the neck portion 23, the crotch portion 24, the shoulder portion 25', and the respective halves 22a > 22b, 23a, 23b, 24a, 24b, 25a, 25b, 27a, 27b of the foot portion 27 are The forming of the symmetrical shape of the chain belt 10 is sandwiched from the front and back of the chain belt 10, respectively. Here, the respective halves 23a' 23b, 24a, 24b, 25a, 25b, 27a, 27b except the aforementioned engaging head portion 22 are welded and integrated on both the front and back sides of the chain belt 10. The half portions 22a and 22b of the engaging head portion 22 which are formed by sandwiching the chain belt 10 and being symmetrically formed above and below, and the end edge 11a of the fastener element mounting edge portion 11 of the fastener tape 10 are only slightly exposed to the outside, and The end edge 11a is formed to extend in parallel to the outside. At this time, the exposed length L1 of the end edge 11a of the sprocket mounting edge portion 11 extending from the shoulder portion 25 is set such that the exposed end face and the opposite chain of the end edge 11a are engaged with the opposite engaging head portion 22. The exposed end faces of the belt 10 are crimped to each other. Therefore, in the engaged state, the opposite end faces of the chain belt 1 压 are pressed against each other to exhibit waterproof performance. On the other hand, the neck portion 23, the crotch portion 24, the shoulder portion 25, and the respective halves 23a, 23b, 24a, 24b, 25a, 25b, 27a, 27b of the foot portion 27 are all tightly fixed to the chain belt 10. The chain teeth are provided with a rim portion 11. Wherein, the thickness of each of the neck portions 23a, 23b, 24a, 24b of the neck portion 23 and the crotch portion 24 is -12-(10) 1306744 degrees, and the shoulders 25 and the halves 25a, 25b, 27a of the foot portion 27 are half thick. The thickness of the 27b is about 1/3 of the thickness of each of the neck portions 23a, 23b, 24a, 24b of the neck portion 23 and the crotch portion 24. Further, the outer surface of the half portion 2 2 a, 2 2 b of the engaging head portion 2 2 is located on the same plane as the outer surface of each of the neck portions 23a, 23b; 24a, 24b of the neck portion 23 and the flange portion 24. With this configuration, when the sprocket teeth 21 are engaged with each other, as shown in Figs. 1 and 3, the half portions 25a and 25b of the shoulder portions 25 of the left and right adjacent sprocket teeth 21 abut against one of the sprocket teeth 21 It engages the inner faces of the halves 22a, 22b of the head 22. In the waterproof slide fastener 1 of the present embodiment, the fastener element 21 having the above configuration is composed of a polymer alloy of a polyurethane resin and an ABS resin. The sprocket 2 composed of a polymer alloy is composited with a polyurethane resin to improve the anchor strength of the fastener tape 10 with the waterproof layer 13 on which the polyurethane elastomer is formed. Further, by the combination of the ABS resin, the formability and rigidity of the fastener elements 21 can be improved. Further, the polyurethane resin-based thermoplastic resin used in the polymer alloy is different from the polyurethane elastomer formed on the waterproof layer 13 of the fastener tape 10, and is harder than the elastomer. The elastomer is so easy to extend. In particular, the fastener element 21 is composed of a polymer alloy in which the ratio of the polyurethane resin to the ABS resin (polyurethane resin/ABS resin) is 20/80 to 5 0/5 0 by weight. When the weight ratio of the polyurethane resin is less than 20%, sufficient anchoring strength cannot be obtained between the chains, and the fastener element 2 1 is easily broken due to insufficient strength, and the meshing strength of the zipper 1 may be lowered. On the other hand, if the weight ratio of the ABS resin is less than 50%, the formability and rigidity of the fastener elements 21 - 13 - (11) 1306744 may be insufficient, which may cause the meshing strength of the zipper 1 to be lowered. The system has a transmission chain for the cavity to be used for the shape of the bullet. The ester of the ester is fixed in the form of an amine with a fixed state. The cover is also covered. To build a model and to build it up and to use the method to prepare it. Next, the pieces of the polyurethane resin and the pieces of the ABS resin are separately mixed and melted by a specific weight, and the molten resin material is introduced into the cavity of the mold through a runner, a flow path, and a gate. Next, the molten resin introduced into the cavity passes through the through hole 14 of the fastener tape 10, and the lower half of the symmetrical element 21 is formed on the front and back sides of the element mounting edge portion 11, and the upper and lower halves are formed in the through hole. The joint portion 2 8 is formed into a molded joint. Thereby, the waterproof slide fastener 1 of the present embodiment shown in Figs. 1 to 3 is obtained. In the waterproof slide fastener 1 of the present embodiment as described above, the fastener tape 10 and the urethane coating are excellent in adhesion, and have excellent abrasion resistance, and the moldability of the fastener element and The rigidity is also good. In addition, the anchoring strength between the chain and the fastener elements is higher, and the forming is simpler, and the waterproof zipper is excellent in the bending property, the meshing strength, and the watertightness of the chain. [Examples] Hereinafter, the present invention will be specifically described by way of examples. In the present embodiment, five kinds of water-repellent pull-14-(12) 1306744 chains were prepared by mixing ratios of polyurethane resin and ABS resin of different polymer alloys which constitute the fastener elements, and the following evaluations were performed for each slide fastener. . The ratio of the water-repellent zipper of the evaluation object to the evaluation of the polyurethane alloy/ABS resin of the polymer alloy was 20/80 (Example 1) and 3 0/70 (Examples). 2), 5 0/5 0 (Example 3), and 70/30 (Example 4) waterproof zipper, and waterproof zipper which is not mixed with polyurethane resin and which is made of ABS resin (Polyurethane resin/ABS resin = 0/100) (Comparative Example) Next, for the five kinds of waterproof zippers obtained, four of the transverse tensile strength, the protrusion strength, the pull-off strength, and the sliding strength were respectively applied. The project is evaluated. Here, the horizontal tensile strength is a resistance level when the left and right chain belts are stretched in opposite directions to each other at a certain speed in the state in which the waterproof zipper is engaged. The protrusion strength is in the state in which the waterproof zipper is engaged, and the sprocket is resisted when it is pushed up in the direction perpendicular to the chain. The pull-out strength is the state of the chain rack, and the fixed chain belt resists the size when one of the fastener elements is stretched outward in the width direction of the chain belt. In addition, the sliding strength pulls one of the fastener elements toward the length of the chain belt. Resist the size of the resistance. The engagement of the sized zip fasteners is broken when the sprocket is broken and detached from the chain. In addition, in the above-described respective strength evaluations, 20 measurement samples were prepared for each of Examples 1 to 4 and the comparison side, and strength tests were performed on each of the five measurement samples for each evaluation item, and measurement was performed for five measurement samples. The average of 値 is used to evaluate the strength of each waterproof zipper. The results of the transverse tensile strength, the protrusion strength, the pull-off strength, and the sliding strength of the water-repellent slide fasteners of Examples 1 to 4 and Comparative Examples were as shown in Figs. 4-15-(13) 1306744 to 7th, respectively. The figure shows. In addition, for the purpose of providing reference, the transverse zipper strength, protrusion strength, and pull of the conventional waterproof zipper for injection molding of polybutene terephthalate sprocket are carried out on the surface of the chain covered with H YTREL (registered trademark). The de-strength and the sliding strength are also listed on the graphs of Figures 4 to 7. As shown in Fig. 4 to Fig. 7, the water-repellent zipper (polyurethane resin/ABS resin = 30/70) of Example 2 exhibited the highest enthalpy in any strength test, and was confirmed to be a high-quality waterproof zipper. . In addition, in the waterproof zipper of the first embodiment, the pull-out strength exhibits a somewhat lower enthalpy. In the waterproof zipper of the embodiment 3, the protrusion strength exhibits a somewhat lower enthalpy, however, the most important transverse zipper strength of the zipper is It is confirmed to be a waterproof zipper with excellent meshing strength and good quality, which is higher than the conventional waterproof zipper. The pull-out strength and the sliding strength of the water-repellent zipper of Example 4 were substantially equal to those of the conventional waterproof zipper, however, the transverse tensile strength was only a few lower than those of Examples 1 to 3. On the other hand, compared with the zippers of Examples 1 to 4, the horizontal zipper strength and the pull-off strength of the waterproof zipper of the comparative example were inferior. In addition, it was confirmed that each of the water-repellent slide fasteners of Examples 1 to 4 was welded to the urethane-coated object at a high frequency, and it was possible to weld without any problem. As described above, it was confirmed that the water-repellent zippers of Examples 1 to 4 can easily carry the chain tape to the polyurethane-based urethane-based object, and further, it is very soft and the shape and rigidity of the sprocket are very excellent. In particular, Examples 1 to 3 are excellent waterproof zippers having excellent tensile strength, tensile strength, and sliding strength of -16-(14) 1306744. Further, in consideration of the ratio of the weight ratio of the polyurethane resin/ABS resin of the above polymer alloy, a method of, for example, an absorption ratio of an infrared absorption spectrum can be used. Therefore, since the absorption wavelength differs depending on the composition, the detection method of the ratio can be investigated by detecting the absorption amount. The present invention is particularly effective for a waterproof zipper which is required to have a good adhesiveness to a polyurethane-based object.
