Description
本発明は、ワイヤーハーネス固定用粘着シートおよびワイヤーハーネス固定方法に関する。 The present invention relates to a wire harness fixing adhesive sheet and a wire harness fixing method.
従来、自動車等の分野では、電力の供給や信号通信のため、複数の電線を束にしたワイヤーハーネスが用いられており、ワイヤーハーネスを車体等の被着体に固定する粘着シートが種々提案されている。 2. Description of the Related Art Conventionally, in the field of automobiles and the like, a wire harness in which a plurality of electric wires are bundled has been used for power supply and signal communication, and various adhesive sheets for fixing the wire harness to an adherend such as a vehicle body have been proposed. ing.
例えば特許文献１は、低温〜高温で優れた粘着特性を発揮するよう粘着剤の配合が調整された粘着シートを開示しており、例えば特許文献２は、軟質の金属箔からなる基材に粘着剤層を設けた粘着シートを開示している。また、例えば特許文献３は、軟質の金属箔からなる基材、発泡樹脂層、および粘着剤層をこの順序で積層した粘着シートを開示している。 For example, Patent Document 1 discloses a pressure-sensitive adhesive sheet in which the composition of a pressure-sensitive adhesive is adjusted so as to exhibit excellent pressure-sensitive adhesive properties at low to high temperatures. For example, Patent Document 2 discloses a pressure-sensitive adhesive sheet that adheres to a substrate made of a soft metal foil. An adhesive sheet provided with an agent layer is disclosed. Further, for example, Patent Document 3 discloses an adhesive sheet in which a substrate made of a soft metal foil, a foamed resin layer, and an adhesive layer are laminated in this order.
基材が金属箔からなる粘着シートは、樹脂からなる粘着シートに比べて難燃性が高いため自動車等の分野での使用に適しており、また、温度上昇にともなって破断強度が低下し難く高温適性を有する。また金属箔は容易に塑性変形するため、貼付対象への形状追従性および変形後の形状保持性（以下、これらの特性をまとめて単に賦形性と称す）に優れる。 The pressure-sensitive adhesive sheet whose base material is made of metal foil is suitable for use in the field of automobiles and the like because of its higher flame retardancy as compared with the pressure-sensitive adhesive sheet made of resin, and the breaking strength is hardly reduced with increasing temperature. Has high temperature suitability. Further, since the metal foil is easily plastically deformed, the metal foil is excellent in shape followability to a sticking target and shape retention after deformation (hereinafter, these characteristics are collectively referred to simply as formability).
しかしながら、金属箔は引裂きに対する強度が小さくちぎれ易いため、貼り付けの際に例えばスキージー等の平板状でへりが僅かに尖った道具や爪が押し当てられると、不用意に破れて貼り付け作業が妨げられる虞がある。 However, since metal foil has a small strength against tearing and is easily torn, if a flat tool with a slightly sharp edge such as a squeegee or a nail is pressed against the metal foil during the application, it may be inadvertently broken and the application work may become difficult. There is a possibility that it will be hindered.
また、従来技術のように金属箔に発泡樹脂層を積層させれば、比較的ちぎれ難くはなるものの、一旦貼り付けられた粘着シートを剥がそうとして大きな力が加えられると、実際には発泡樹脂層に破壊が生じることがあり、そのため、貼り直し作業が手間取る虞がある。 Also, if a foamed resin layer is laminated on a metal foil as in the prior art, it will be relatively difficult to tear off, but once a large force is applied to peel off the adhered adhesive sheet, the foamed resin layer is actually removed. The layer may be broken, and thus the re-sticking operation may take time.
そこで、本発明は、それらの課題に鑑みてなされたものであり、難燃性、高温適性、および賦形性が良好で、かつ貼り付けおよび貼り直しをし易いワイヤーハーネス固定用粘着シートおよびワイヤーハーネス固定方法を提供することを目的とする。 Therefore, the present invention has been made in view of these problems, and has a flame-retardant property, high-temperature suitability, and good shapeability, and is easy to apply and re-apply.

上記目的を達成するための本発明のワイヤーハーネス固定方法は、金属箔である基材、および当該基材の一方の面の側に設けられた粘着剤層を有するワイヤーハーネス固定用粘着シートを、ワイヤーハーネスおよび被着体にまたがって貼り付け、前記ワイヤーハーネスを前記被着体に固定する。前記ワイヤーハーネス固定用粘着シートは、前記基材の一方の面と前記粘着剤層との間に、前記基材と剥離しないよう一体に設けられた樹脂フィルムを有しており、本発明のワイヤーハーネス固定方法は、前記ワイヤーハーネス固定用粘着シートを、前記ワイヤーハーネスの円弧状の外周と前記被着体の面との接触箇所のきわに向かって押し込み、前記ワイヤーハーネスおよび前記被着体に沿って貼り付ける。 The wire harness fixing method of the present invention for achieving the above object, a base material that is a metal foil, and a wire harness fixing pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer provided on one side of the base material, Affixing over the wire harness and the adherend, the wire harness is fixed to the adherend. The wire harness fixing pressure-sensitive adhesive sheet has a resin film integrally provided between one surface of the base material and the pressure-sensitive adhesive layer so as not to peel off from the base material. In the harness fixing method, the wire harness fixing pressure-sensitive adhesive sheet is pushed toward a point of contact between an arc-shaped outer periphery of the wire harness and a surface of the adherend, and is pushed along the wire harness and the adherend. And paste.
上記目的を達成するための本発明のワイヤーハーネス固定方法は、金属箔である基材、および当該基材の一方の面の側に設けられた粘着剤層を有するワイヤーハーネス固定用粘着シートを、ワイヤーハーネスおよび被着体にまたがって貼り付け、前記ワイヤーハーネスを前記被着体に固定する。前記ワイヤーハーネス固定用粘着シートは、前記基材の一方の面と前記粘着剤層との間に、前記基材と剥離しないよう一体に設けられた樹脂フィルムを有しており、本発明のワイヤーハーネス固定方法は、前記ワイヤーハーネス固定用粘着シートを、前記ワイヤーハーネスの外周から前記被着体の面にかけて突っ張らせつつ前記被着体の面に押し付けて貼り付ける。 The wire harness fixing method of the present invention for achieving the above object, a base material that is a metal foil, and a wire harness fixing pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer provided on one side of the base material, Affixing over the wire harness and the adherend, the wire harness is fixed to the adherend. The wire harness fixing pressure-sensitive adhesive sheet has a resin film integrally provided between one surface of the base material and the pressure-sensitive adhesive layer so as not to peel off from the base material. In the harness fixing method, the pressure-sensitive adhesive sheet for fixing the wire harness is pressed and attached to the surface of the adherend while being stretched from the outer periphery of the wire harness to the surface of the adherend.
上記構成を有する発明によれば、基材が金属箔であるため、難燃性、高温適性、および賦形性を良好にでき、また、ワイヤーハーネス固定用粘着シートがちぎれるのを樹脂フィルムが妨げるため、貼り付けおよび貼り直しをし易い。 According to the invention having the above configuration, since the base material is a metal foil, flame retardancy, suitability for high temperature, and shapeability can be improved, and the resin film prevents the adhesive sheet for fixing the wire harness from being torn. Therefore, pasting and re-pasting are easy.
以下、添付した図面を参照しながら、本発明の実施形態を説明する。なお、図面の寸法比率は、説明の都合上誇張されており、実際の比率と異なる。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

図１に示すように、実施形態のワイヤーハーネス固定用粘着シート１００（以下、単に粘着シート１００と称す）は、基材１０１、接着剤層１０２、樹脂フィルム１０３、粘着剤層１０４、および剥離ライナー１０５がこの順序で積層された構成を有する。 As shown in FIG. 1, the pressure-sensitive adhesive sheet 100 for fixing a wire harness (hereinafter, simply referred to as pressure-sensitive adhesive sheet 100) according to the embodiment includes a substrate 101, an adhesive layer 102, a resin film 103, a pressure-sensitive adhesive layer 104, and a release liner. 105 have the structure laminated | stacked in this order.
基材１０１は金属箔である。基材１０１を形成する金属箔の材料として、例えば、アルミニウム、鉛、マグネシウム、銅、銀等が挙げられるが、これらに限定されない。基材１０１の厚みは、例えば、７〜１００μｍである。 The base material 101 is a metal foil. Examples of the material of the metal foil forming the base material 101 include, but are not limited to, aluminum, lead, magnesium, copper, and silver. The thickness of the substrate 101 is, for example, 7 to 100 μm.
接着剤層１０２は、基材１０１の一方の面１０６に形成されており、基材１０１と樹脂フィルム１０３とを剥離しないように一体に接着している。接着剤層１０２は、例えばドライラミネート用接着剤からなるが、これに限定されない。 The adhesive layer 102 is formed on one surface 106 of the base material 101 and is integrally bonded so that the base material 101 and the resin film 103 are not separated. The adhesive layer 102 is made of, for example, an adhesive for dry lamination, but is not limited to this.
樹脂フィルム１０３は、発泡体ではなく、非発泡のいわゆるソリッドな状態である。樹脂フィルム１０３は、接着剤層１０２を介さず基材１０１に直接設けられていてもよく、例えば溶融押出法によって、直接、基材１０１に剥離しないよう一体に形成することができる。 The resin film 103 is not a foam but a non-foamed so-called solid state. The resin film 103 may be provided directly on the base material 101 without the interposition of the adhesive layer 102, and can be integrally formed so as not to be directly separated from the base material 101 by, for example, a melt extrusion method.
樹脂フィルム１０３の形成材料は、耐引裂性が良好であることが好ましく、例えば、ポリエチレンテレフタレート（ＰＥＴ）、ポリプロピレン（ＰＰ）、ポリエチレン（ＰＥ）、およびポリ塩化ビニル（ＰＶＣ）からなる群より選択される一種であるが、これらに限定されず、例えば、ポリスチレン（ＰＳ）等であってもよい。ポリ塩化ビニル（ＰＶＣ）、およびポリスチレン（ＰＳ）等は、好ましくは、可塑剤を含ませることによって柔軟性を上げて用いられる。樹脂フィルム１０３の厚みは、例えば、６〜５０μｍである。 The material for forming the resin film 103 preferably has good tear resistance, and is selected, for example, from the group consisting of polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), and polyvinyl chloride (PVC). However, the present invention is not limited thereto, and may be, for example, polystyrene (PS). Polyvinyl chloride (PVC), polystyrene (PS), and the like are preferably used with increased flexibility by including a plasticizer. The thickness of the resin film 103 is, for example, 6 to 50 μm.
粘着剤層１０４は、例えば、アクリル系粘着剤、ゴム系粘着剤、シリコーン系粘着剤、ポリウレタン系粘着剤等によって形成されるが、粘着剤層１０４の形成材料はこれらに限定されない。また、それらの粘着剤は、１種を単独で用いても２種以上を併用してもよい。 The pressure-sensitive adhesive layer 104 is formed of, for example, an acrylic pressure-sensitive adhesive, a rubber-based pressure-sensitive adhesive, a silicone-based pressure-sensitive adhesive, a polyurethane-based pressure-sensitive adhesive, or the like, but the material for forming the pressure-sensitive adhesive layer 104 is not limited thereto. Further, one kind of those pressure-sensitive adhesives may be used alone, or two or more kinds may be used in combination.
剥離ライナー１０５は、粘着剤層１０４の表面に配置されており、剥離自在である。剥離ライナー１０５としては公知のものが使用可能であり、各種樹脂によって形成された剥離フィルムを用いることができる。あるいは、剥離ライナー１０５は、上質紙、クラフト紙、グラシン紙等の紙基材の表面に、シリコーン等の剥離剤が塗布された構成を有していてもよい。 The release liner 105 is disposed on the surface of the pressure-sensitive adhesive layer 104 and is peelable. A known release liner 105 can be used, and a release film formed of various resins can be used. Alternatively, the release liner 105 may have a configuration in which a release agent such as silicone is applied to the surface of a paper base material such as high-quality paper, kraft paper, or glassine paper.
図２に示すように、粘着シート１００は、ワイヤーハーネス１１０を被着体１２０に固定するのに用いられる。作業者は、粘着シート１００から剥離ライナー１０５を剥がし、露出した粘着剤層１０４を介して、粘着シート１００をワイヤーハーネス１１０の外周および被着体１２０の面にまたがって貼り付けてそれらを固定する。作業者は、粘着シート１００を複数個所に貼り付け、ワイヤーハーネス１１０を被着体１２０に沿わせて固定する。 As shown in FIG. 2, the adhesive sheet 100 is used to fix the wire harness 110 to the adherend 120. The operator peels off the release liner 105 from the adhesive sheet 100, attaches the adhesive sheet 100 to the outer periphery of the wire harness 110 and the surface of the adherend 120 via the exposed adhesive layer 104, and fixes them. . The worker attaches the adhesive sheet 100 to a plurality of places, and fixes the wire harness 110 along the adherend 120.
粘着シート１００は、一旦貼り付けられた後に手で剥がすことが可能である。例えば貼り直しが必要な場合、作業者は、貼り付けた粘着シート１００を手で剥がしてそれを再度貼り付けてもよい。 The adhesive sheet 100 can be peeled off by hand after being once attached. For example, when re-attachment is necessary, the worker may peel off the adhered adhesive sheet 100 by hand and attach it again.
ワイヤーハーネス１１０は、コルゲートチューブ１１１、およびその内部を通る複数の電線１１２を有するが、その構成は特に限定されない。例えば、コルゲートチューブ１１１がなく、複数の電線１１２が、その周りに巻き付けられたテープによって束ねられた構成であってもよい。 The wire harness 110 has a corrugated tube 111 and a plurality of electric wires 112 passing therethrough, but the configuration is not particularly limited. For example, a configuration in which the corrugated tube 111 is not provided and a plurality of electric wires 112 are bundled by a tape wound around the electric wires 112 may be employed.
また、本実施形態ではワイヤーハーネス１１０が２つに分岐しているが、分岐の数や位置も特に限定されず、３つ以上に分岐していてもよく、また分岐箇所が複数あってもよい。また、複数本のコルゲートチューブ１１１が隣接して略平行に並び、粘着シート１００がそれらをまとめて固定していてもよい。ワイヤーハーネス１１０は、電力供給または信号通信等に利用される。 Further, in the present embodiment, the wire harness 110 is branched into two, but the number and position of the branches are not particularly limited, and may be branched into three or more, or a plurality of branch locations may be provided. . Alternatively, the plurality of corrugated tubes 111 may be adjacently arranged in substantially parallel, and the adhesive sheet 100 may fix them together. The wire harness 110 is used for power supply or signal communication.
被着体１２０は、本実施形態では簡単な例として平らな板の形態で開示されているが、これに限定されず、湾曲した形状や凹凸形状を有していてもよい。例えば、被着体１２０として、自動車のルーフパネル、ピラー、バンパー、ルーフライニング、ドアトリム等、自動車の車体または内装を構成する部材が挙げられ、また、被着体１２０の材質も、金属に限定されず、樹脂、または不織布等の繊維材であってもよい。 In the present embodiment, the adherend 120 is disclosed in the form of a flat plate as a simple example, but is not limited thereto, and may have a curved shape or an uneven shape. For example, as the adherend 120, members constituting the body or interior of the automobile, such as an automobile roof panel, pillar, bumper, roof lining, and door trim, may be mentioned, and the material of the adherend 120 is also limited to metal. Instead, it may be a resin or a fibrous material such as a nonwoven fabric.
図３に示すように、粘着シート１００は、ワイヤーハーネス１１０の円弧状の外周と被着体１２０の面との接触箇所１３０のきわ１３１において、鋭角に曲げられてワイヤーハーネス１１０および被着体１２０に沿って貼り付けられている。 As shown in FIG. 3, the pressure-sensitive adhesive sheet 100 is bent at an acute angle at a crevice 131 at a contact point 130 between the arc-shaped outer periphery of the wire harness 110 and the surface of the adherend 120, and the wire harness 110 and the adherend 120 are bent. It is pasted along.
図４に示すように、そのような貼り付け状態にするため、作業者は、接触箇所１３０のきわ１３１に向かって粘着シート１００を押し込みつつ、ワイヤーハーネス１１０および被着体１２０に沿って粘着シート１００を貼り付ける。この際、作業者は、例えばスキージーＳ等の平板状でへりが僅かに尖った道具を用いるが、これに限定されず、道具を用いることなく例えば爪の先で粘着シート１００を押し込んでもよい。 As shown in FIG. 4, in order to make such an affixed state, the worker pushes the adhesive sheet 100 toward the crevice 131 of the contact point 130, while pressing the adhesive sheet along the wire harness 110 and the adherend 120. Paste 100. At this time, the operator uses a flat tool with a slightly sharp edge such as a squeegee S, for example, but is not limited to this. The operator may press the adhesive sheet 100 with a tip of a nail without using the tool.
粘着シート１００は、ワイヤーハーネス１１０および被着体１２０に貼り付けられてそれらを固定できればよく、作業者は、粘着シート１００をワイヤーハーネス１１０に先に貼り付けた後に被着体１２０に貼り付けるようにしてもよいし、被着体１２０に先に貼り付けた後にワイヤーハーネス１１０に貼り付けるようにしてもよく、粘着シート１００をワイヤーハーネス１１０および被着体１２０に対してどのような順序で貼り付けていくかは、特に限定されない。いずれにしても、作業者は、接触箇所１３０のきわ１３１に向かって粘着シート１００を押し込み、ワイヤーハーネス１１０および被着体１２０に沿って粘着シート１００を貼り付ける。 The adhesive sheet 100 only needs to be attached to the wire harness 110 and the adherend 120 so that they can be fixed. The worker may attach the adhesive sheet 100 to the wire harness 110 first and then attach the adhesive sheet 100 to the adherend 120. Alternatively, the adhesive sheet 100 may be attached to the wire harness 110 after being attached to the adherend 120 first, and the adhesive sheet 100 may be attached to the wire harness 110 and the adherend 120 in any order. How to attach is not particularly limited. In any case, the worker pushes the adhesive sheet 100 toward the crevice 131 of the contact point 130 and attaches the adhesive sheet 100 along the wire harness 110 and the adherend 120.
次に本実施形態の作用効果を述べる。 Next, the operation and effect of this embodiment will be described.
本実施形態の粘着シート１００は、金属箔である基材１０１を有する。このため、難燃性を高めることができる。また、基材１０１が金属箔であるため、温度上昇しても破断強度が低下し難く、高温適性が優れる。また、金属箔は容易に塑性変形し、賦形性に優れるため、粘着シート１００がワイヤーハーネス１１０および被着体１２０の形状に良好に追従して変形し、またその変形後の形状が保持され易い。従って、粘着シート１００をワイヤーハーネス１１０および被着体１２０に沿わせて確実に貼り付けられる。 The pressure-sensitive adhesive sheet 100 of the present embodiment has a base material 101 that is a metal foil. Therefore, flame retardancy can be improved. Further, since the base material 101 is a metal foil, the breaking strength does not easily decrease even when the temperature rises, and the high temperature suitability is excellent. In addition, since the metal foil is easily plastically deformed and excellent in shapeability, the pressure-sensitive adhesive sheet 100 is deformed in a good manner following the shapes of the wire harness 110 and the adherend 120, and the shape after the deformation is maintained. easy. Therefore, the pressure-sensitive adhesive sheet 100 can be securely adhered along the wire harness 110 and the adherend 120.
さらに本実施形態では、粘着シート１００は、金属箔である基材１０１と剥離しないよう一体に設けられた樹脂フィルム１０３を有している。この構成によって、粘着シート１００では、単純な面方向の引っ張りに対する強度（破断強度）が増しているだけでなく、引裂きに対する強度も増している。引裂きは、一般的に、部分的に生じた裂け目をきっかけとして急速に進行するが、樹脂フィルム１０３が設けられることによって、引裂きのきっかけ自体が生じ難くなる。 Further, in the present embodiment, the pressure-sensitive adhesive sheet 100 has a resin film 103 provided integrally with the base material 101 which is a metal foil so as not to peel off. With this configuration, in the pressure-sensitive adhesive sheet 100, not only the strength (breaking strength) against simple tension in the plane direction but also the strength against tearing increases. In general, tearing proceeds rapidly due to a partially generated tear. However, the provision of the resin film 103 makes it difficult for the tearing itself to occur.
このように本実施形態では樹脂フィルム１０３によって引裂きに対する強度が増しているため、貼り付けの際に例えばスキージーＳ等の平板状でへりが僅かに尖った道具や爪が押し当てられたり、あるいは一旦貼り付けられた後に引き剥がすために大きな力が加えられたりしても、粘着シート１００がちぎれ難い。従って、本実施形態によれば粘着シート１００の貼り付けおよび貼り直しをし易い。 As described above, in the present embodiment, since the strength against tearing is increased by the resin film 103, a tool or a nail having a slightly sharp edge such as a squeegee S or the like is pressed or affixed at the time of attachment. Even if a large force is applied to peel off the sheet after the sheet is pasted, the pressure-sensitive adhesive sheet 100 is hardly torn. Therefore, according to this embodiment, the adhesive sheet 100 can be easily attached and reattached.
特に、樹脂フィルム１０３の形成材料が、ポリエチレンテレフタレート（ＰＥＴ）、ポリプロピレン（ＰＰ）、ポリエチレン（ＰＥ）、およびポリ塩化ビニル（ＰＶＣ）からなる群より選択される一種であれば、耐引裂性が優れるため、引裂きによる粘着シート１００のちぎれをより効果的に妨げることができる。 In particular, if the material for forming the resin film 103 is one selected from the group consisting of polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), and polyvinyl chloride (PVC), the tear resistance is excellent. Therefore, tearing of the adhesive sheet 100 due to tearing can be more effectively prevented.
本実施形態では、粘着シート１００が接触箇所１３０のきわ１３１に向かって押し込まれ、きわ１３１において鋭角に曲げられてワイヤーハーネス１１０および被着体１２０に沿って貼り付けられている。これによって、粘着シート１００がワイヤーハーネス１１０および被着体１２０の形状に沿って広範囲に密着するため、例えば振動が加わったり時間が経過したりしても粘着シート１００の浮きや剥がれが生じ難く、ワイヤーハーネス１１０を確実に固定しておくことができる。 In the present embodiment, the pressure-sensitive adhesive sheet 100 is pushed toward the crevice 131 of the contact portion 130, is bent at an acute angle at the crevice 131, and is adhered along the wire harness 110 and the adherend 120. Thereby, since the pressure-sensitive adhesive sheet 100 adheres widely over the shape of the wire harness 110 and the adherend 120, even if, for example, vibration is applied or time elapses, the pressure-sensitive adhesive sheet 100 is unlikely to float or peel off, The wire harness 110 can be securely fixed.

比較例１〜５の粘着シートは、上記実施形態の積層構造とは異なり、２層または３層の積層構造からなる。 The pressure-sensitive adhesive sheets of Comparative Examples 1 to 5 are different from the laminated structure of the above embodiment and have a two-layer or three-layer laminated structure.
比較例１の粘着シートは、厚み５０μｍのアルミ箔の一方の面に、粘着剤層が設けられた２層からなる。 The pressure-sensitive adhesive sheet of Comparative Example 1 was composed of two layers in which a pressure-sensitive adhesive layer was provided on one surface of an aluminum foil having a thickness of 50 μm.

実施例１〜５および比較例１〜５の粘着シートは、いずれも、短辺が５ｃｍで長辺が１０ｃｍの長方形の形状を有する。 Each of the pressure-sensitive adhesive sheets of Examples 1 to 5 and Comparative Examples 1 to 5 has a rectangular shape with a short side of 5 cm and a long side of 10 cm.
難燃性については、ＦＭＶＳＳ Ｎｏ．３０２（Ｆｅｄｅｒａｌ Ｍｏｔｏｒ Ｖｅｈｉｃｌｅ ｓａｆｅｔｙ Ｓｔａｎｄａｒｄｓ Ｎｏ．３０２）に従って試験を行い、その規格に定められた判定基準に適合するか否かを確認した。 Regarding the flame retardancy, FMVSS No. A test was carried out in accordance with Federal Motor Vehicle Safety Standards No. 302 (Fedal Motor Vehicle Safety Standards No. 302), and it was confirmed whether or not the test conformed to the criterion defined in the standard.
賦形性については、直径１３ｍｍのコルゲートチューブのまわりに実施例および比較例の各粘着シートを巻き、コルゲートチューブの形状に追従してそのまま形状が保持されるかどうかを調べた。このとき、実施例１〜５および比較例１〜５のそれぞれで粘着剤層を設けず、粘着シートをコルゲートチューブに貼り付けることはしなかった。 Regarding the shapeability, each of the pressure-sensitive adhesive sheets of Examples and Comparative Examples was wound around a corrugated tube having a diameter of 13 mm, and it was checked whether or not the shape was maintained as it was following the shape of the corrugated tube. At this time, the pressure-sensitive adhesive layer was not provided in each of Examples 1 to 5 and Comparative Examples 1 to 5, and the pressure-sensitive adhesive sheet was not attached to the corrugated tube.
粘着シートが力を加えられることによってコルゲートチューブの形状に容易に追従し、力を加えるのを止めてもそのまま形状を保持した場合、表１の賦形性の欄ではそのことを○印によって示した。 When the pressure-sensitive adhesive sheet is easily applied, it easily follows the shape of the corrugated tube, and when the application of the force is stopped, the shape is maintained as it is. Was.
粘着シートが力を加えられることによってコルゲートチューブの形状に追従するが、力を加えるのを止めると略平坦な形状に復元する場合、表１の賦形性の欄ではそのことを×印によって示した。 When the pressure-sensitive adhesive sheet follows the shape of the corrugated tube due to the application of force, but returns to a substantially flat shape when the application of the force is stopped, this is indicated by a cross in the column of shaping properties in Table 1. Was.
粘着シートに力を加えてコルゲートチューブの形状に追従させた状態から力を加えるのを止めた際、粘着シートがある程度復元するものの略平坦な形状までは復元しない場合、表１の賦形性の欄ではそのことを△印によって示した。 When the force is applied to the adhesive sheet and the application of the force is stopped from following the corrugated tube, the adhesive sheet recovers to some extent but does not recover to a substantially flat shape. In the column, this is indicated by a triangle.
高温適性については、８０℃の環境下で各粘着シートを面方向に引っ張って破断強度を測定した。破断強度が１０Ｎ／１５ｍｍ以上の場合、表１ではそのことを○印によって示した。破断強度が１０Ｎ／１５ｍｍ未満の場合、表１ではそのことを×印によって示した。高温適性が良好であれば、高温下で荷重がかかった際に粘着シートが伸び難いため、高温下でもワイヤーハーネスを確実に保持でき、例えばワイヤーハーネスの落下を防止できる。 Regarding the suitability for high temperature, each adhesive sheet was pulled in the surface direction under an environment of 80 ° C., and the breaking strength was measured. In the case where the breaking strength is 10 N / 15 mm or more, the fact is indicated by a circle in Table 1. In the case where the breaking strength is less than 10 N / 15 mm, the fact is indicated by an X mark in Table 1. If the suitability for high temperature is good, the pressure-sensitive adhesive sheet is unlikely to stretch when a load is applied at high temperature, so that the wire harness can be securely held even at high temperature, and for example, the fall of the wire harness can be prevented.
貼付作業性については、図４のようにコルゲートチューブと被着体との接触箇所のきわに向かって粘着シートをスキージーによって押し込み、そのときの粘着シートの破れの有無を確認した。ここで、スキージーによって粘着シートを押し込む力は、１９．８Ｎとした。粘着シートに破れが生じなかった場合、表１ではそのことを○印によって示した。粘着シートに破れが生じた場合、表１ではそのことを×印によって示した。 As for the sticking workability, as shown in FIG. 4, the adhesive sheet was pushed with a squeegee toward the edge of the contact point between the corrugated tube and the adherend, and the presence or absence of tearing of the adhesive sheet at that time was confirmed. Here, the force for pushing the adhesive sheet by the squeegee was 19.8N. In the case where the adhesive sheet was not broken, this is indicated by a mark in Table 1. In the case where the pressure-sensitive adhesive sheet is torn, this is indicated in Table 1 by crosses.
貼り直し適性については、粘着シートを塗装鋼板に２ｋｇ荷重で貼り付け、その１分後、粘着シートを１８０°裏返すように剥がしていき、粘着シートがちぎれることなく剥離するか否かを調べた。 Regarding the suitability for re-attaching, the pressure-sensitive adhesive sheet was bonded to a coated steel plate at a load of 2 kg, and after one minute, the pressure-sensitive adhesive sheet was peeled off so as to be turned upside down by 180 °, and it was examined whether or not the pressure-sensitive adhesive sheet was peeled without tearing.
粘着シートがちぎれることなく塗装鋼板と粘着剤層との界面で剥離していった場合、表１の貼り直し適性の欄ではそのことを○印によって示した。一方、アルミ箔に発泡樹脂層が設けられた比較例５では、剥離にともなって発泡樹脂層に破壊が生じ、発泡樹脂層の一部が被着体に貼り付いたまま残った。表１の貼り直し適性の欄では、そのことを×印によって示した。 In the case where the pressure-sensitive adhesive sheet was peeled off at the interface between the coated steel sheet and the pressure-sensitive adhesive layer without being torn, this was indicated by a mark in the column of suitability for re-sticking in Table 1. On the other hand, in Comparative Example 5 in which the foamed resin layer was provided on the aluminum foil, the foamed resin layer was broken with the peeling, and a part of the foamed resin layer remained adhered to the adherend. In the column of suitability for reattachment in Table 1, this is indicated by the mark x.
次に実施例と比較例との対比について述べる。 Next, a comparison between the example and the comparative example will be described.
比較例１と実施例１〜５とを比較すると、それらはいずれもアルミ箔（金属箔）を備えるため、難燃性、賦形性、および高温適性が優れるが、樹脂フィルムのない比較例１では、引裂きに対する強度が小さく、貼り付けの際に押し込まれると粘着シートがちぎれ、貼付作業性が不良であった。これに対し、樹脂フィルムを有する実施例１〜５によれば、貼り付けの際に粘着シートがちぎれず、貼付作業性が良好であった。 Comparing Comparative Example 1 with Examples 1 to 5, they all have an aluminum foil (metal foil), and therefore have excellent flame retardancy, shapeability, and high temperature suitability, but Comparative Example 1 having no resin film. In this case, the strength against tearing was low, and the adhesive sheet was torn when pushed in during the pasting, resulting in poor pasting workability. On the other hand, according to Examples 1 to 5 having the resin film, the adhesive sheet was not torn at the time of sticking, and the sticking workability was good.
貼り直し適性については、樹脂フィルムのない比較例１、および樹脂フィルムを有する実施例１〜５は、いずれも○であったが、粘着シートを被着体に貼り付ける際の荷重や粘着剤層の粘着力が大きくなると、それにともなって剥離に要する力も大きくなるため、樹脂フィルムのない比較例１は、樹脂フィルムを有する実施例１〜５に比べ、剥離の際にちぎれ易くなる。このため、比較例１の粘着シートは、被着体に軽く貼り付けられた状態から剥がす際にはちぎれ難いが、被着体にしっかり貼り付けられた状態から剥がそうとすると、ちぎれる虞がある。 Regarding the re-applying property, Comparative Example 1 having no resin film and Examples 1 to 5 having the resin film were all ○, but the load and pressure-sensitive adhesive layer when the pressure-sensitive adhesive sheet was bonded to the adherend were When the adhesive force of the resin film increases, the force required for peeling increases accordingly. Therefore, Comparative Example 1 having no resin film is more likely to be torn off during peeling than Examples 1 to 5 having a resin film. For this reason, the pressure-sensitive adhesive sheet of Comparative Example 1 is unlikely to be torn when peeled from the state where it is lightly attached to the adherend, but may be torn when peeled from the state where it is firmly adhered to the adherend. .
また、比較例２〜４は、樹脂フィルムからなり、そのため耐引裂性は良好であるものの、それらは金属箔を備えていないため、難燃性、賦形性、および高温適性のうちの少なくとも２つが実施例１〜５に比べて劣っていた。 Further, Comparative Examples 2 to 4 are made of a resin film and thus have good tear resistance, but since they do not have a metal foil, they have at least two of flame retardancy, shapeability, and high temperature suitability. One was inferior to Examples 1-5.
また、比較例５では、アルミ箔に発泡樹脂層が積層された粘着シートを、一旦貼り付けられた状態から剥がすと、発泡樹脂層に破壊が生じてしまい貼り直し適性が不良であった。これに対し、実施例１〜５では、アルミ箔に積層された樹脂フィルムが剥離の際にちぎれず、貼り直し適性が良好であった。 Further, in Comparative Example 5, when the pressure-sensitive adhesive sheet in which the foamed resin layer was laminated on the aluminum foil was once peeled off from the state of being pasted, the foamed resin layer was broken and reattached, and the suitability was poor. On the other hand, in Examples 1 to 5, the resin film laminated on the aluminum foil was not broken at the time of peeling, and was suitable for reattaching.
また、比較例５の粘着シートは、アルミ箔を有するものの、火に弱い発泡樹脂層が設けられているため、比較例５の難燃性は、実施例１〜５に比べて劣っていた。 Moreover, although the pressure-sensitive adhesive sheet of Comparative Example 5 had an aluminum foil, but was provided with a foamed resin layer that was vulnerable to fire, the flame retardancy of Comparative Example 5 was inferior to Examples 1 to 5.
本発明は、上述した実施形態および実施例に限定されるものではなく、特許請求の範囲内で種々改変できる。 The present invention is not limited to the above embodiments and examples, but can be variously modified within the scope of the claims.
例えば、粘着シートの形状は、特に限定されず、テープ状の細長い形状であってもよいし、枚葉紙のような矩形の形状であってもよいし、それら以外の形状であってもよい。また、粘着シートの大きさも特に限定されない。 For example, the shape of the pressure-sensitive adhesive sheet is not particularly limited, and may be a tape-like elongated shape, a rectangular shape like a sheet of paper, or any other shape. . Further, the size of the pressure-sensitive adhesive sheet is not particularly limited.
また、上記実施形態の粘着シート１００では、剥離ライナー１０５と他の構成要素とが同じ形状および大きさであるが、これに限定されず、剥離ライナーが他の構成要素に比べて大きくてもよい。例えば、長尺な剥離ライナーに、その長手方向に沿って複数組の粘着シートが設けられるようにしてもよい。 In the pressure-sensitive adhesive sheet 100 of the above embodiment, the release liner 105 and other components have the same shape and size, but are not limited thereto, and the release liner may be larger than the other components. . For example, a long release liner may be provided with a plurality of sets of pressure-sensitive adhesive sheets along the longitudinal direction.
また、上記実施形態では粘着シート１００がきわ１３１に押し込まれて貼り付けられているが、本発明は、この形態に限定されず、きわ１３１に向かって押し込まれることなく貼り付けられた形態も含む。 Further, in the above embodiment, the pressure-sensitive adhesive sheet 100 is pressed into and adhered to the crevice 131, but the present invention is not limited to this form, and includes a form in which the pressure-sensitive adhesive sheet 100 is adhered without being pushed toward the crevice 131. .
その例として図５に示す形態では、粘着シート１００が、ワイヤーハーネス１１０の外周から被着体１２０の面１２１にかけて折れ曲がることなく面状に突っ張った状態で貼り付けられている。 As an example, in the embodiment shown in FIG. 5, the pressure-sensitive adhesive sheet 100 is stuck from the outer periphery of the wire harness 110 to the surface 121 of the adherend 120 in a state where the pressure-sensitive adhesive sheet 100 is stretched without bending.
このような貼付状態にするため、作業者は、ワイヤーハーネス１１０の外周から被着体１２０の面１２１にかけて、例えばスキージーＳを用いて粘着シート１００を突っ張らせつつ面１２１に押し付けて貼り付ける。このとき、作業者は、スキージーＳ等の道具を用いず、例えば爪の先で粘着シート１００を面１２１に押し付けてもよい。 In order to make such an attached state, the worker presses and adheres to the surface 121 from the outer periphery of the wire harness 110 to the surface 121 of the adherend 120 while stretching the adhesive sheet 100 using, for example, a squeegee S. At this time, the worker may press the adhesive sheet 100 against the surface 121 with a tip of a nail, for example, without using a tool such as the squeegee S.
粘着シート１００を突っ張った状態に貼り付けるためにスキージーＳ等の道具や爪の先が押し当てられたとしても、粘着シート１００は樹脂フィルム１０３を含んで耐引裂性が増しているため、ちぎれ難い。 Even if a tool such as a squeegee S or the tip of a nail is pressed against the pressure-sensitive adhesive sheet 100 in a stretched state, the pressure-sensitive adhesive sheet 100 includes the resin film 103 and has an increased tear resistance, so that it is difficult to tear. .
また、図５に示した形態では、粘着シート１００がワイヤーハーネス１１０の外周から面１２１にかけて突っ張った状態に貼り付けられることによって、ワイヤーハーネス１１０が被着体１２０から離間しないように押さえつけられる。このため、ワイヤーハーネス１１０を被着体１２０にしっかり密着させて固定できる。 Further, in the embodiment shown in FIG. 5, the adhesive sheet 100 is stuck from the outer periphery of the wire harness 110 to the surface 121 so that the wire harness 110 is pressed down so as not to separate from the adherend 120. For this reason, the wire harness 110 can be firmly adhered to the adherend 120 and fixed.
