Description
本発明は、ワイヤハーネス特に自動車用のワイヤハーネスの結束、緩衝用粘着シートに関する。 The present invention relates to a wire harness, in particular, a wire harness for automobiles, and an adhesive sheet for buffering.
自動車の車体に沿って配索されるワイヤハーネスは、従来主として用いられている材料としては発泡ポリウレタン樹脂が知られている。このものは連続気泡であるために、耐水性がなく、また、ワイヤハーネスと他の部材との摩擦音、緩衝音が大きいという問題がある。特開2006-127022号公報は第一樹脂層にポリエチレン、ポリウレタンなどの発泡してない樹脂層を設け、第二樹脂層に発泡ウレタン(ソフトウレタンテープといわれている)を設けており、その代表的な構造として直接電線をテープで一体にするものもあるが、二層構成でコスト高である。特開2006-120415号公報にはポリエチレン、ナイロンなどのテープにエンボス加工したものが記載されているが、周囲温度や、過電流による温度上昇に対する配慮はなされていない。特開2002-78168テープ本体に粘着面を設け、反対面に多数の凹凸を設けているが、使用材料はポリ塩化ビニルやポリエチレンで、前者の塩化ビニルは燃焼時に塩素を発生することで、良好な環境保持上好ましいものではなく、後者のポリエチレンは雰囲気温度で軟化したり、ワイヤに過電流が流れたときに、本来持っている性能を発揮できない。特許第3087623号公報に記載の発明は基材の片面に多数の突起を隙間を空けて突設しているが、隙間が放熱、断熱効果を奏し、緩衝音の低減作用を奏するとの記述はあるが、材料の樹脂には塩化ビニルやウレタン樹脂を想定させる記述があるだけでポリエチレンについての記述は全くない。 For wire harnesses routed along the body of an automobile, polyurethane foam resin is known as a material mainly used conventionally. Since this is an open cell, there is no water resistance, and there is a problem that the frictional noise and the buffering noise between the wire harness and other members are large. Japanese Patent Application Laid-Open No. 2006-127022 provides a first resin layer with a non-foamed resin layer such as polyethylene and polyurethane, and a second resin layer with foamed urethane (referred to as soft urethane tape). As a typical structure, there is one in which electric wires are directly integrated with tape, but the cost is high due to the two-layer structure. Japanese Patent Application Laid-Open No. 2006-120415 describes an embossed tape made of polyethylene, nylon, or the like, but no consideration is given to an ambient temperature or a temperature increase due to overcurrent. JP 2002-78168 A tape body is provided with an adhesive surface and a number of irregularities are provided on the opposite surface. The material used is polyvinyl chloride or polyethylene, and the former vinyl chloride is good because it generates chlorine during combustion. The latter polyethylene is not preferable for maintaining the environment, and the latter polyethylene cannot exhibit its inherent performance when softened at ambient temperature or when an overcurrent flows through the wire. In the invention described in Japanese Patent No. 3087623, a large number of protrusions are provided on one side of the base material with gaps therebetween, but the description that the gaps have a heat dissipation and heat insulation effect and a buffering noise reduction function is described. Although there is a description that assumes that the material resin is vinyl chloride or urethane resin, there is no description of polyethylene.
従来技術には種々のものがあるが、もっとも多く用いられている発泡ポリウレタンは連続気泡を有するもので、衝撃吸収性はよいが、連続多孔性であるために、結露水などの水を吸収しやすいことや、厚みが大きく、引張り強さが小さく、摩擦による緩衝音の抑制向上も要望されるところである。 There are various types of prior art, but the most commonly used polyurethane foam has open cells and good shock absorption, but because it is continuous porous, it absorbs water such as condensed water. There are also demands for ease of use, large thickness, low tensile strength, and suppression of buffer noise due to friction.
また、ポリエチレンなどの耐水性に優れたテープでは、引張り強さなどの機械的強度にも優れているが、緩衝作用に乏しい。また、架橋されていないポリエチレンを発泡させたものは独立気泡であり、引張り強さ、緩衝性、摩擦時の緩衝音の抑制効果には優れているが、雰囲気、環境が、エンジンであることから、万一異常高温あるいは、電線の過電流による温度上昇により、軟化して、本来持っている諸特性を損なうという問題点がある。 Further, a tape excellent in water resistance such as polyethylene has excellent mechanical strength such as tensile strength, but has a poor buffering effect. In addition, foamed non-crosslinked polyethylene is a closed cell, which is excellent in tensile strength, shock absorbing properties, and the effect of suppressing shock noise during friction, but because the atmosphere and environment are the engine. However, in the unlikely event that it is abnormally hot or the temperature rises due to overcurrent of the wire, it softens and damages its inherent properties.
本発明者は、上記目的を達成するために鋭意検討した結果、電線に対して取り付け作業性の良いテープ材を改良したもので、通常用いられている低密度ポリエチレンやこれを発泡(独立気泡)させたテープに留まらず、架橋することで従来の発泡ポリエチレンテープの耐熱性が低い点を改良し、しかも引張り強度、圧縮強度に優れ、摩擦音の発生も少なくしたワイヤハーネス結束、緩衝用粘着シートを提供するものである。 As a result of diligent studies to achieve the above object, the present inventor has improved a tape material having good workability for mounting on an electric wire. A wire harness bundling and cushioning adhesive sheet that improves the low heat resistance of conventional foamed polyethylene tape by cross-linking, not only the tape that has been made, but also has excellent tensile and compressive strength and less frictional noise. It is to provide.
より詳細には、本発明は、一本の電線又は複数の電線群の外周に巻きつけあるいはこれらが当たる部分の内装材面、外板面に貼り付けて、結束し、緩衝用に使用されるワイヤハーネス結束、緩衝用シートであって、架橋発泡ポリエチレンをテープ基材とし、エンボス加工が設けられていることを特徴とするワイヤハーネス結束、緩衝用粘着シートである(請求項1)。 More specifically, the present invention is used for cushioning by winding around the outer periphery of a single electric wire or a plurality of electric wire groups or attaching them to an interior material surface or an outer plate surface where they hit each other. Wire harness bundling and cushioning sheet, comprising a cross-linked foamed polyethylene as a tape base material, and embossing is provided.
更に、エンボス加工した凹凸模様の加工面の表面が外面で、裏面が背面であるシートの裏面に粘着剤層を設けて電線束に密着させて固定できるようにされているので、シート材と電線との間に隙間が発生しない(請求項2)。 Furthermore, the surface of the embossed concavo-convex pattern surface is the outer surface, and the back surface is the back surface. An adhesive layer is provided on the back surface of the sheet so that it can be fixed in close contact with the wire bundle. There is no gap between the two (claim 2).
エンボス加工は素材が発泡していることに加えて凸部がバリやエッジと接触して電線への接触を緩和する緩衝材として電線保護機能を具備しているが、エンボス形状は、菱形,円、長円、長方形の微細な結合模様で形成されていることで、粘着シートとしての性能を保持しながら、微細凹凸によりその好ましい機能を発揮するものである(請求項3)。 In addition to foaming the material, the embossing has a wire protection function as a cushioning material that relaxes contact with the wire by protruding parts coming into contact with burrs and edges. In addition, by being formed with an ellipse or rectangular fine bonding pattern, the preferable function is exhibited by fine irregularities while maintaining the performance as an adhesive sheet.
すなわち、独立気泡の発泡体の緩衝性とエンボス加工の緩衝性とで、好ましい引張り強度等を維持しながら、防音性も備えたもので、配索性にも優れたものを提供する。 That is, it provides a sound-proofing property while maintaining a preferable tensile strength and the like with a buffering property of a closed-cell foam and a buffering property of embossing, and provides an excellent cableability.
なお、本発明においてシートにはテープ及び幅や長さなど形状がテープとは云い難いものを含めているものとしている。 In the present invention, the sheet includes a tape and a sheet whose shape such as width and length is difficult to say.
また、架橋発泡ポリエチレンシートの製造は、通常ポリエチレンシートを発泡剤の分解温度に加熱して発泡させて、微細な独立気泡の発泡ポリエチレンシートを製造する。 In the production of the crosslinked foamed polyethylene sheet, the polyethylene sheet is usually heated to the decomposition temperature of the foaming agent and foamed to produce a fine closed cell foamed polyethylene sheet.
この際化学架橋させる場合は、過酸化物やシラン架橋剤を配合しておけばよいが、電子線照射の場合は、過酸化物などを配合しなくても架橋できる。シートの製造は押し出し方法でも、バッチ方式でも良い。 In this case, when chemical crosslinking is performed, a peroxide or a silane crosslinking agent may be blended. However, in the case of electron beam irradiation, crosslinking can be performed without blending a peroxide or the like. The sheet may be produced by an extrusion method or a batch method.
本発明によれば、シート基材に耐水性があるので、結露などの水の影響は全く受けない。また、引張り強度、圧縮強度に優れ、ワイヤハーネスに使用した場合、緩衝音が極めて小さくしかもコストが低廉で、例えば広幅のシートを作製しておき、使用頻度を考慮した数種の幅のシートに切断して用意しておくことで、材料に無駄がなく、管理することができる。 According to the present invention, since the sheet base material has water resistance, it is not affected at all by water such as condensation. In addition, it has excellent tensile strength and compressive strength, and when used for a wire harness, the cushioning sound is extremely low and the cost is low.For example, a wide sheet is prepared, and the sheet has several widths considering the frequency of use. By cutting and preparing, the material can be managed without waste.
なお塩化ビニルや発泡ポリウレタンは燃焼したときに、有害なガスを発生するので、自動車の事故による火災は勿論、廃棄物処理の点からも、他の材料の出現が待望されるところである。 Since vinyl chloride and polyurethane foam generate harmful gas when burned, the appearance of other materials is awaited from the viewpoint of waste disposal as well as fire caused by automobile accidents.
なお、ポリエチレンに代えてEPDMを用いることは材料がコスト高になり、好ましくない。 Note that it is not preferable to use EPDM instead of polyethylene because the material becomes expensive.
以下本発明の形態について図面を参照しつつ説明する。図1は、架橋発泡ポリエチレン11において、エンボス加工されたものの表面図が示されている。
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a surface view of the cross-linked
図2は、図1の部分拡大図で、凹部12、凸部13を構成するように、エンボス加工された状態を示し、図では幅方向に、同一形状の凹部12と同一形状の凸部13とが、幅方向に連続し、縦方向(長さ方向)に交互に存在するようにエンボス加工され一定の模様を形成している。
FIG. 2 is a partially enlarged view of FIG. 1 and shows an embossed state so as to constitute the
例えば図2において、隣接する長円状の凹部の中心間の距離は2.3mm、長円の短径は0.3mm、また、凸部の中心の円状の凹部の径は1.2mmで、凹部の深さはいずれも0.6mm〜0.7mmのエンボス加工された模様のものを形成できるが、エンボス模様はこれに限られるものではない。 For example, in FIG. 2, the distance between the centers of adjacent ellipsoidal recesses is 2.3 mm, the minor axis of the ellipse is 0.3 mm, and the diameter of the circular recess at the center of the projection is 1.2 mm. The depth of the recesses can be any embossed pattern of 0.6 mm to 0.7 mm, but the embossed pattern is not limited to this.
図3は本発明のワイヤハーネス結束、緩衝用粘着シートの断面図の一例で、凹部12と凸部13が形成された架橋発泡ポリエチレンシートからなり、裏面には粘着剤塗布層14及びその表面の離形シート15が示されている。
FIG. 3 is an example of a cross-sectional view of the wire harness bundling and cushioning adhesive sheet of the present invention, which is composed of a crosslinked foamed polyethylene
上記架橋発泡とエンボス加工は、衝撃を吸収する作用を発揮する。 The above-mentioned cross-linking foaming and embossing have an effect of absorbing an impact.
本発明の粘着シートはエンボス加工面を表面側に、粘着剤付与面を内面にして巻きつけて使用される。 The pressure-sensitive adhesive sheet of the present invention is used by being wound with the embossed surface on the surface side and the pressure-sensitive adhesive application surface on the inner surface.
本発明において用いられる、架橋発泡ポリエチレンシートには、例えば積水化学工業社製の商品名ソフトロンが用いられる。また、粘着剤には、例えば東洋インキ製造株式会社製の二液硬化型アクリル系粘着剤が用いられる。 As the cross-linked foamed polyethylene sheet used in the present invention, for example, trade name Softlon manufactured by Sekisui Chemical Co., Ltd. is used. Moreover, for example, a two-component curable acrylic pressure-sensitive adhesive manufactured by Toyo Ink Manufacturing Co., Ltd. is used as the pressure-sensitive adhesive.
なお、本発明の実施に当たっては、幅広のシート材料を25mm幅、40mm幅、75mm幅、150mm幅にカットして、20m巻、30m巻のものとすれば、実用的に有利に使用である。 In practicing the present invention, if a wide sheet material is cut into 25 mm width, 40 mm width, 75 mm width, and 150 mm width to make 20 m roll and 30 m roll, it is practically advantageous to use.

Incidentally, the test sample represents no cushioning material (corrugated) · urethane foam sheet (foam) 4t (sushi roll) and foamed PE emboss (both 200 mm long, t is thickness mm).
測音機・・・リオンNA−27型を用いた。 Sound meter: Lion NA-27 type was used.
試験板を水平な台の上に置き、試験用テープと試験版の接触部から10mm離れた位置で、測音できるように測音機を設置した。 The test plate was placed on a horizontal table, and a sound measuring device was installed so that sound measurement was possible at a position 10 mm away from the contact portion between the test tape and the test plate.
なお、摩擦音の試験方法は、試験片を手動で、1回、約30mm引張り、その際に試験用テープと試験板が摩擦することにより発生する音を測定した。 In addition, the test method of the frictional sound measured the sound generated by manually pulling the test piece once about 30 mm and rubbing the test tape and the test plate at that time.

また、使用されるワイヤハーネスを、衝撃や摩擦から守り、十分保護することはできない。 Moreover, the used wire harness cannot be protected sufficiently from protection against impact and friction.
なお、ポリエチレンに代えてEPDMを用いることはコスト高になり、好ましくない。 In addition, it is not preferable to use EPDM instead of polyethylene because it increases costs.
上記において示された本発明のワイヤハーネス結束、緩衝用シートは、必要に応じて、使用しやすいようにカットしたテープ巻きとして準備することができる。 The wire harness bundling and cushioning sheet of the present invention shown above can be prepared as a tape winding cut for ease of use, if necessary.
好ましいシートは、架橋度が5〜160重量%で、気泡のアスペクト比(MDの平均気泡径/CDの平均気泡径)は0.25〜1である。 A preferable sheet has a cross-linking degree of 5 to 160% by weight, and a bubble aspect ratio (average bubble diameter of MD / average bubble diameter of CD) of 0.25 to 1.
本発明の架橋発泡ポリエチレンシートは、発泡してないポリエチレンシートに比べて、自動車に配索された保護効果が、ウレタン発泡体よりこすれ音低減の効果が大きい。しかし、この発泡ポリエチレンシートに一様に微細な凹凸模様を付与したものを用いた場合は、模様を利用して切れやすくなり、種々のサイズや形状に対応しやすいので、低コストで、保護効果が得られる。また、前記模様の効果として該発泡ポリエチレンシートを曲げても皺を発生しにくいので、好ましい保護構造が得られる利点がある。 The cross-linked foamed polyethylene sheet of the present invention has a greater effect of reducing the rubbing sound than the urethane foam, as compared to a non-foamed polyethylene sheet. However, when using a foamed polyethylene sheet with a uniform fine concavo-convex pattern, it is easy to cut using the pattern, and it is easy to adapt to various sizes and shapes, so it is inexpensive and has a protective effect. Is obtained. In addition, as an effect of the pattern, it is difficult to generate wrinkles even when the foamed polyethylene sheet is bent, and thus there is an advantage that a preferable protective structure can be obtained.
本発明のワイヤハーネス用の架橋発泡ポリエチレンシートは、従来のこの種テープと同様に、ワイヤハーネスに巻きつけて使用される。 The crosslinked foamed polyethylene sheet for a wire harness of the present invention is used by being wound around a wire harness in the same manner as this conventional tape.
使用に当たっては電線に直接巻きつけるほか、コネクタの周囲にも巻きつけて使用できる。コルゲート管を用いる場合は、その周囲にも巻きつけて使用可能である。 In use, it can be wrapped directly around the wire or around the connector. When a corrugated tube is used, it can be wound around the periphery.
また、一様に微細な凹凸模様を付与した本発明の架橋発泡ポリエチレンシートは、図1に示すように、凹部と凸部とで微細な模様を形成しているので、シートのどの部分でも同様に使用でき、厚さも模様が細かいほど一定になる。又、シートであるから、一重巻き、多重巻きいずれの要求にも対応できる。 Moreover, since the cross-linked foamed polyethylene sheet of the present invention uniformly provided with a fine concavo-convex pattern forms a fine pattern with concave portions and convex portions as shown in FIG. 1, it is the same in any part of the sheet. The thickness becomes constant as the pattern becomes finer. Moreover, since it is a sheet | seat, it can respond to any request | requirement of single winding and multiple winding.
また、本発明の架橋発泡ポリエチレンシートは、従来用いられている発泡ポリウレタンシートより引張り強度、圧縮強度が表1に示すように優れており、また、本発明における架橋発泡ポリエチレンシートと、架橋してない発泡ポリエチレンシート及びコルゲートとを比較すると表1に示すように、引裂強度は強くなり、最高使用温度が10℃位高くなるので、周囲温度の上昇に耐え、エンボス加工したシートの外観を考察すると、無架橋品は、気泡が大きく、粗大な凹凸があるのに対して、本発明によるものは、気泡が小さく平滑な表面を有し、被巻き付部、重ね巻き部などにおいて空隙の発生するおそれが少ない、などの効果を奏することができる。 Further, the crosslinked foamed polyethylene sheet of the present invention is superior in tensile strength and compressive strength to those of conventionally used foamed polyurethane sheets as shown in Table 1, and is crosslinked with the crosslinked foamed polyethylene sheet of the present invention. As shown in Table 1, when the foamed polyethylene sheet and the corrugated sheet are compared, the tear strength becomes stronger and the maximum operating temperature is increased by about 10 ° C., so that it can withstand the increase in ambient temperature and the appearance of the embossed sheet is considered. The non-crosslinked product has large bubbles and rough irregularities, whereas the non-crosslinked product according to the present invention has a small surface and a smooth surface, and voids are generated in the portion to be wound, the lap winding portion, etc. It is possible to achieve effects such as less fear.
また、本発明で用いられる架橋発泡ポリエチレンシートは劣化しがたいなどの特徴がある。 Moreover, the crosslinked foamed polyethylene sheet used in the present invention has a feature that it is difficult to deteriorate.
より詳細には、本発明は、一本の電線又は複数の電線群の外周に巻きつけあるいはこれらが当たる部分の内装材面、外板面に貼り付けて、結束し、緩衝用に使用されるワイヤハーネス結束、緩衝用シートであって、架橋発泡ポリエチレンをシート基材とし、エンボス加工が設けられていることを特徴とするワイヤハーネス結束、緩衝用粘着シートである(請求項1)。
More specifically, the present invention is used for cushioning by winding around the outer periphery of a single electric wire or a plurality of electric wire groups or attaching them to an interior material surface or an outer plate surface where they hit each other. Wire harness bundling and cushioning sheet, which is a wire harness bundling and buffering pressure-sensitive adhesive sheet characterized in that a cross-linked foamed polyethylene is used as a sheet base material and embossing is provided (Claim 1).

なお発泡ポリウレタンは燃焼したときに、有害なガスを発生するので、自動車の事故による火災は勿論、廃棄物処理の点からも、他の材料の出現が待望されるところであったが、本発明はこれを解決したものである。
また、使用されるワイヤハーネスを、衝撃や摩擦から守り、十分保護することはできない。
In addition, since polyurethane foam generates harmful gas when it burns, the appearance of other materials has been awaited from the viewpoint of waste disposal as well as fire due to automobile accidents. This is a solution.
Moreover, the used wire harness cannot be protected sufficiently from protection against impact and friction.
自動車の車体に沿って配索されるワイヤハーネスは、従来主として用いられている材料としては発泡ポリウレタン樹脂が知られている。このものは連続気泡であるために、耐水性がなく、また、ワイヤハーネスと他の部材との摩擦音、緩衝音が大きいという問題がある。特開2008-127022号公報は第一樹脂層にポリエチレン、ポリウレタンなどの発泡してない樹脂層を設け、第二樹脂層に発泡ウレタン(ソフトウレタンテープといわれている)を設けており、その代表的な構造として直接電線をテープで一体にするものもあるが、二層構成でコスト高である。特開2008-120415号公報にはポリエチレン、ナイロンなどのテープにエンボス加工したものが記載されているが、周囲温度や、過電流による温度上昇に対する配慮はなされていない。特開2002-78168テープ本体に粘着面を設け、反対面に多数の凹凸を設けているが、使用材料はポリ塩化ビニルやポリエチレンで、前者の塩化ビニルは燃焼時に塩素を発生することで、良好な環境保持上好ましいものではなく、後者のポリエチレンは雰囲気温度で軟化したり、ワイヤに過電流が流れたときに、本来持っている性能を発揮できない。特許第3087623号公報に記載の発明は基材の片面に多数の突起を隙間を空けて突設しているが、隙間が放熱、断熱効果を奏し、緩衝音の低減作用を奏するとの記述はあるが、材料の樹脂には塩化ビニルやウレタン樹脂を想定させる記述があるだけでポリエチレンについての記述は全くない。
For wire harnesses routed along the body of an automobile, polyurethane foam resin is known as a material mainly used conventionally. Since this is an open cell, there is no water resistance, and there is a problem that the frictional noise and the buffering noise between the wire harness and other members are large. JP 200 8 -127 022 discloses a polyethylene in the first resin layer, a resin layer not expanded, such as polyurethane is provided, and provided with a urethane foam (it is said that soft urethane tape) to the second resin layer, the A typical structure is one in which electric wires are directly integrated with a tape, but the cost is high due to the two-layer structure. JP 200 8 -120 415 issue Publication polyethylene, those embossed tape such as nylon is described, and the ambient temperature, no consideration is made with respect to the temperature increase due to overcurrent. JP 2002-78168 A tape body is provided with an adhesive surface and a number of irregularities are provided on the opposite surface. The material used is polyvinyl chloride or polyethylene, and the former vinyl chloride is good because it generates chlorine during combustion. The latter polyethylene is not preferable for maintaining the environment, and the latter polyethylene cannot exhibit its inherent performance when softened at ambient temperature or when an overcurrent flows through the wire. In the invention described in Japanese Patent No. 3087623, a large number of protrusions are provided on one side of the base material with gaps therebetween, but the description that the gaps have a heat dissipation and heat insulation effect and a buffering noise reduction function is described. Although there is a description that assumes that the material resin is vinyl chloride or urethane resin, there is no description of polyethylene.
エンボス加工は素材が発泡していることに加えて凸部がバリやエッジと接触して電線への接触を緩和する緩衝材として電線保護機能を具備しているが、エンボス形状は、円、長円の微細な結合模様で形成されていることで、粘着シートとしての性能を保持しながら、微細凹凸によりその好ましい機能を発揮するものである(請求項3)。
In addition to foaming the material, the embossing has a wire protection function as a cushioning material that relaxes the contact with the wire by contacting the burrs and edges, but the embossed shape is circular , long By being formed with a fine bonding pattern of circles, the preferable function is exhibited by the fine unevenness while maintaining the performance as an adhesive sheet (Claim 3).
