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 pressure-sensitive 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。 Conventionally, in the field of automobiles and the like, wire harnesses in which a plurality of electric wires are bundled for power supply and signal communication have been used, 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 the pressure-sensitive adhesive is adjusted so as to exhibit excellent pressure-sensitive adhesive properties at low to high temperatures. For example, Patent Document 2 adheres to a substrate made of a soft metal foil. An adhesive sheet provided with an agent layer is disclosed. For example, patent document 3 is disclosing the adhesive sheet which laminated | stacked the base material which consists of soft metal foil, the foamed resin layer, and the adhesive layer 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 made of a metal foil is more suitable for use in the field of automobiles and the like because it has higher flame retardancy than a pressure-sensitive adhesive sheet made of resin, and the breaking strength is unlikely to decrease with increasing temperature.

Further, since the metal foil is easily plastically deformed, it is excellent in shape followability to the object to be pasted and shape retention after deformation (hereinafter, these characteristics are simply referred to 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 the strength against tearing is small and the metal foil is easy to tear, for example, if a flat tool such as a squeegee or a tool with a slightly sharp edge is pressed against the metal foil, it may be inadvertently torn and pasted. There is a risk of being disturbed.
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。 In addition, if a foamed resin layer is laminated on a metal foil as in the prior art, it will be relatively difficult to tear, but if a large force is applied to peel off the adhesive sheet once attached, the foamed resin actually There is a possibility that the layer may be broken, and there is a possibility that the re-sticking work may be troublesome.

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. In addition, the dimension ratio of drawing is exaggerated on account of description, and differs from an actual ratio.
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 wire harness fixing pressure-sensitive adhesive sheet 100 (hereinafter simply referred to as pressure-sensitive adhesive sheet 100) of the embodiment includes a base material 101, an adhesive layer 102, a resin film 103, a pressure-sensitive adhesive layer 104, and a release liner. 105 has a configuration in which the layers are 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 metal foil material forming the base material 101 include, but are not limited to, aluminum, lead, magnesium, copper, silver, and the like. The thickness of the base material 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 substrate 101, and is bonded together so that the substrate 101 and the resin film 103 are not peeled off. The adhesive layer 102 is made of, for example, an adhesive for dry lamination, but is not limited thereto.
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 is a non-foamed so-called solid state. The resin film 103 may be directly provided on the base material 101 without using the adhesive layer 102, and can be integrally formed so as not to be peeled directly 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 from the group consisting of, for example, polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), and polyvinyl chloride (PVC). However, the present invention is not limited to these, 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. Moreover, those adhesives may be used individually by 1 type, or may use 2 or more types together.
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. As the release liner 105, a known one 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 substrate such as high-quality paper, craft 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 and affixes the adhesive sheet 100 across the outer periphery of the wire harness 110 and the surface of the adherend 120 via the exposed adhesive layer 104 to fix them. . An operator attaches the adhesive sheet 100 to a plurality of locations, 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 pressure-sensitive adhesive sheet 100 can be peeled off by hand after it has been pasted. For example, when re-sticking is necessary, the operator may peel off the attached adhesive sheet 100 by hand and re-attach it.
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。 Although the wire harness 110 has the corrugated tube 111 and the some electric wire 112 which passes through the inside, the structure is not specifically limited. For example, there may be 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 corrugated tube 111.
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。 Moreover, in this embodiment, although the wire harness 110 has branched into two, the number and position of a branch are not specifically limited, It may branch into three or more, and there may be two or more branch locations. . Further, a plurality of corrugated tubes 111 may be adjacently arranged in 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 this embodiment, the adherend 120 is disclosed in the form of a flat plate as a simple example. However, the adherend 120 is not limited thereto, and may have a curved shape or an uneven shape. For example, examples of the adherend 120 include members constituting an automobile body or interior such as an automobile roof panel, pillar, bumper, roof lining, door trim, etc. The material of the adherend 120 is also limited to metal. Alternatively, it may be a fiber material such as a resin or 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 wrinkle 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. 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 obtain such an attached state, the operator pushes the adhesive sheet 100 toward the wrinkle 131 of the contact location 130, and the adhesive sheet along the wire harness 110 and the adherend 120. Paste 100. At this time, the operator uses a flat tool such as a squeegee S with a slightly sharp edge, but is not limited to this, and the operator may push the adhesive sheet 100 with the 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 may be attached to the wire harness 110 and the adherend 120 so that they can be fixed, and the operator attaches the adhesive sheet 100 to the adherend 120 after attaching the adhesive sheet 100 to the wire harness 110 first. 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. There is no particular limitation as to whether to attach it. In any case, the operator pushes the pressure-sensitive adhesive sheet 100 toward the contact 131 of the contact point 130 and attaches the pressure-sensitive 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 function 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 this embodiment has a base material 101 that is a metal foil. For this reason, a flame retardance can be improved. Moreover, since the base material 101 is a metal foil, even if the temperature rises, the breaking strength does not easily decrease, and high temperature aptitude is excellent. Further, since the metal foil is easily plastically deformed and has excellent formability, the pressure-sensitive adhesive sheet 100 deforms following the shape of the wire harness 110 and the adherend 120 well, and the shape after the deformation is maintained. easy. Therefore, the adhesive sheet 100 is securely attached 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。 Furthermore, in this embodiment, the adhesive sheet 100 has the resin film 103 provided integrally so that it may not peel with the base material 101 which is metal foil. With this configuration, the pressure-sensitive adhesive sheet 100 not only has an increased strength (breaking strength) against pulling in a simple plane direction, but also has an increased strength against tearing. In general, tearing proceeds rapidly as a trigger for a partially generated tear, but the provision of the resin film 103 makes it difficult for the trigger for tearing 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。 Thus, in this embodiment, since the strength against tearing is increased by the resin film 103, a flat tool such as a squeegee S or a tool with a slightly sharp edge is pressed against the surface, or once attached, Even if a large force is applied to peel off after being attached, the adhesive sheet 100 is difficult to tear off. Therefore, according to this embodiment, it is easy to attach and reattach the adhesive sheet 100.
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 forming material of 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 prevented more effectively.
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 wrinkle 131 of the contact location 130, bent at an acute angle at the wrinkle 131, and attached along the wire harness 110 and the adherend 120. Thereby, since the adhesive sheet 100 adheres in a wide range along the shape of the wire harness 110 and the adherend 120, for example, even if vibration is applied or time elapses, the adhesive sheet 100 is unlikely to float or peel off. The wire harness 110 can be securely fixed.

<Example>
While actually producing the pressure-sensitive adhesive sheets of Examples 1 to 5 having a configuration according to the pressure-sensitive adhesive sheet 100 of the above-described embodiment, the pressure-sensitive adhesive sheets of Comparative Examples 1 to 5 having a configuration different from those are prepared. The test results were compared between the example and the comparative example with respect to the five items of flame retardancy, formability, high temperature suitability, sticking workability, and reattachability.

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。 Unlike the laminated structure of the said embodiment, the adhesive sheet of Comparative Examples 1-5 consists of a laminated structure of 2 layers or 3 layers.
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 consists of two layers in which a pressure-sensitive adhesive layer is provided on one surface of an aluminum foil having a thickness of 50 μm.

比較例５の粘着シートは、厚み３０μｍのアルミ箔に発泡ポリエチレン（ＰＥ）の層を積層し、発泡ポリエチレンの層に粘着剤層を設けた３層からなる。 The pressure-sensitive adhesive sheet of Comparative Example 5 is composed of three layers in which a foamed polyethylene (PE) layer is laminated on an aluminum foil having a thickness of 30 μm, and a pressure-sensitive adhesive layer is provided on the foamed polyethylene layer.
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 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。 For flame retardancy, FMVSS No. The test was conducted according to 302 (Federal Motor Vehicle Safety Standards No. 302), and it was confirmed whether or not the judgment criteria defined in the standard were met.
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 formability, each pressure-sensitive adhesive sheet of Examples and Comparative Examples was wound around a corrugated tube having a diameter of 13 mm, and it was examined whether the shape was maintained as it was following the shape of the corrugated tube. At this time, the adhesive layer was not provided in each of Examples 1 to 5 and Comparative Examples 1 to 5, and the 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。 If the pressure-sensitive adhesive sheet easily follows the shape of the corrugated tube by applying a force and keeps the shape as it is even if the force is stopped, this is indicated by a circle in the column of formability in Table 1. It 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 by applying a force, but when it is restored to a substantially flat shape when the force is stopped, this is indicated by a cross in the formability column of Table 1. It 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 applying pressure to the pressure-sensitive adhesive sheet to stop applying force from the state of following the shape of the corrugated tube, the pressure-sensitive adhesive sheet recovers to some extent but does not recover to a substantially flat shape. This is indicated by a triangle in the column.
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。 About high temperature aptitude, each adhesive sheet was pulled to the surface direction in the environment of 80 degreeC, and the breaking strength was measured. In the case where the breaking strength is 10 N / 15 mm or more, this is indicated by a circle in Table 1. When the breaking strength is less than 10 N / 15 mm, in Table 1, this is indicated by a cross. If the high temperature aptitude is good, the adhesive sheet is difficult to stretch when a load is applied at a high temperature. Therefore, the wire harness can be securely held even at a high temperature, and for example, the wire harness can be prevented from falling.
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。 Regarding the workability of attaching, as shown in FIG. 4, the pressure-sensitive adhesive sheet was pushed by a squeegee toward the contact point between the corrugated tube and the adherend, and whether or not the pressure-sensitive adhesive sheet was torn was confirmed. Here, the force which pushes an adhesive sheet with a squeegee was 19.8N. When tearing did not occur in the pressure-sensitive adhesive sheet, in Table 1, this was indicated by a circle. In the case where the adhesive sheet is torn, this is indicated by x in Table 1.
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。 As for the re-applicability, the pressure-sensitive adhesive sheet was affixed to the coated steel plate with a load of 2 kg, and after 1 minute, the pressure-sensitive adhesive sheet was peeled off so that it was turned 180 °, and it was examined whether 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。 When the pressure-sensitive adhesive sheet peeled off at the interface between the coated steel sheet and the pressure-sensitive adhesive layer without tearing, this was indicated by a circle in the re-applicability column 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 due to peeling, and a part of the foamed resin layer remained attached to the adherend. In the re-paste suitability column of Table 1, this is indicated by a cross.
次に実施例と比較例との対比について述べる。 Next, the 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 and Examples 1 to 5, they all have an aluminum foil (metal foil), and thus are excellent in flame retardancy, formability, and high-temperature suitability, but Comparative Example 1 without a resin film. Then, the strength against tearing was small, and the adhesive sheet was torn off when pushed in during pasting, resulting in poor pasting workability. On the other hand, according to Examples 1-5 which have a 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 re-applicability, Comparative Example 1 without a resin film and Examples 1 to 5 having a resin film were all good, but the load and adhesive layer when the adhesive sheet was attached to the adherend Since the force required for peeling increases as the adhesive strength increases, Comparative Example 1 without a resin film is more easily broken at the time of peeling compared to Examples 1 to 5 having a resin film. For this reason, the pressure-sensitive adhesive sheet of Comparative Example 1 is difficult to tear off when it is peeled off from the lightly attached state to the adherend, but may be peeled off if it is peeled off from the state firmly attached 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。 In addition, Comparative Examples 2 to 4 are made of a resin film and thus have good tear resistance, but since they do not include a metal foil, at least two of flame retardancy, formability, and high temperature suitability. 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。 Moreover, in Comparative Example 5, when the pressure-sensitive adhesive sheet in which the foamed resin layer was laminated on the aluminum foil was peeled off from the state where it was once stuck, the foamed resin layer was broken, and the re-adhesiveness was poor. On the other hand, in Examples 1-5, the resin film laminated | stacked on the aluminum foil was not torn off in the case of peeling, and the reapplyability was favorable.
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 adhesive sheet of the comparative example 5 has aluminum foil, since the foaming resin layer weak to a fire is provided, the flame retardance of the comparative example 5 was inferior compared with Examples 1-5.
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-described embodiments and examples, and various modifications can be made 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 such as a sheet of paper, or a shape other than those. . Moreover, the magnitude | size of an adhesive sheet is not specifically limited, either.
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 according to the above-described embodiment, the release liner 105 and other components have the same shape and size, but the present invention is not limited to this, and the release liner may be larger than other components. . For example, a plurality of sets of pressure-sensitive adhesive sheets may be provided on a long release liner along the longitudinal direction thereof.
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。 Moreover, in the said embodiment, although the adhesive sheet 100 is pushed in and stuck on the wrinkle 131, this invention is not limited to this form, The form stuck without being pushed toward the wrinkle 131 is also included. .
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 form shown in FIG. 5, the pressure-sensitive adhesive sheet 100 is attached in a state of being stretched in a planar shape without being bent from the outer periphery of the wire harness 110 to the surface 121 of the adherend 120.
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 a sticking state, the worker presses and sticks the pressure-sensitive adhesive sheet 100 on the surface 121 using the squeegee S, for example, from the outer periphery of the wire harness 110 to the surface 121 of the adherend 120. At this time, the operator may press the adhesive sheet 100 against the surface 121 with the tip of a nail 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 a tip of a nail is pressed to stick the adhesive sheet 100 in a stretched state, the adhesive sheet 100 includes the resin film 103 and has increased tear resistance, so 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 form shown in FIG. 5, the wire harness 110 is pressed so as not to be separated from the adherend 120 by being stuck in a state of being stretched from the outer periphery of the wire harness 110 to the surface 121. For this reason, the wire harness 110 can be fixed firmly to the adherend 120.
