Description

【0001】
【産業上の利用分野】
本発明は、帯電防止機能を備えた車輌用の内装材に関する。
【0002】
【従来の技術】
周知の如く、静電気は摩擦により全ての物質に発生する。そして、人への帯電では、例えば、気象条件、周囲の環境(着用する衣服、衣服の材料、又は体質)等により区々であること、又は人によって、強い違和感があり、また怪我の虞と、また強い衝撃を受けることから、極めて不愉快であること、等の問題がある。このような帯電による不都合は、本発明が意図する車輌では、車体の一部が導体としての役割を担うことから、一層深刻であり、例えば、運転者、搭乗者等にとっては、避けられない問題である。
【0003】
以上のような不都合があることから、一般的には、車体より静電気を除去する手段が採用されている。例えば、アース用のパーツ(アースにより強制的に減衰させる)、又はアースグッズ等があり、その一部は実用に供されている。しかし、この種の静電気除去手段は、取付け等が面倒であること、消耗による取替えの必要性、粉塵による(僅かであるが)悪影響、又は乾燥時等の状態では、効果が少なく、一時的なこと、等からそれ程、普及しないのが現況である。
【0004】
以上の問題を本質的に改良する発明として、車輌のシート、又はボディ、内装材等に、帯電防止機能を備えた表面材(表皮材)、内装材等に関する発明が散見される。その一部を文献として説明するが、以下の文献(1)と、文献(2)である。
【0005】
: 文献(1)は、特開2000−79653の車輌シート用表面材およびその製造方法である。その内容は、表面材は、ワディング材の表面にカーボンエマルジョンを散布して表層部に導電ウェブ層を形成し、この表面にホットメルト製の接着層を形成し、これを導電性繊維が混入されて帯電防止機能を有する表皮材と積層・圧締後、厚み方向に熱風を通過させてワディング材と表皮材とを接着一体化し、次いで所定厚みとなるよう冷間 プレスで製造する。そして、この表面材は、帯電防止機能を有する表皮材と、カーボンエマルジョンの散布により表層部に形成された導電ウェブ層との間に、繊維系のワディング材がカーボンエマルジョンを混在させた接着層を介して接着一体化する構成である。これにより、自動車のシートカバー等に用いる帯電防止機能に優れかつ風合いにも優れた車輌シート用表面材を提供できる特徴がある。しかし、この文献(1)は、カーボンエマルジョンの散布により表層部に導電ウェブ層を形成する構成である。従って、導電ウェブ層の耐久性に改良の余地がある。またワディング材とカーボンエマルジョンとの馴染みが十分とは云えないと考えられることから、使用頻度と、衝撃を受け易いシートの表面材としては、改良の余地が考えられる。
【0006】
: 文献(2)は、特開平10−278698号の自動車用内装材とその製造方法である。その内容は、カーボン繊維と樹脂繊維とを混合し、この混合したものをニードル(針)により絡合状態とし(混織し)、この絡合状態の素材(絡合繊維フレキシブル素材)を加熱、樹脂溶融し、この加熱状態において所定の厚みに圧縮する構成である。従って、帯電防止機能に優れかつ超軽量で高強度を有する自動車用内装材を提供できる特徴がある。しかし、この文献(2)は、コストの上昇を招くこと、又は廃棄の際に、手間と環境汚染(二次公害発生)回避等の処理が必要であり、面倒であること、また廃棄に関して問題が考えられること、等の改良点が見受けられる。
【0007】
また本発明が使用する紙製の静電気除去防止構造体に関する文献としては、下記の文献(3)がある。
【0008】
: この文献(3)は、特開平7−3697号のカーボンブラック含有紙の発明である。この発明は、カーボンブラックを分散した木材パルプ、木綿繊維、綿花、植物パルプ、回収古紙等でなるセルロース系繊維スラリーに、カルボキシ変性ポリマーのアニオン系ラテックス、又は水性分散材等を加えた後、定着し、抄紙時に助剤を添加し、抄紙製造することを特徴とするカーボンブラック含有紙であり、カーボンブラック含有量が大で、カーボン粉体の脱離が小さく、かつ強度の大きい紙が得られること、又は紙は、静電気除去防止材、電磁波シールド材、面状発熱体等に利用できること、又はカーボンの脱落防止が図れること、等が記述されている。しかし、この文献(3)は、カーボンブラックを含有するセルロース系繊維スラリーに、樹脂性接着材(カルボキシ変性ポリマーのアニオン系ラテックス)、又は水性分散材等を加えたカーボンブラック含有紙である。従って、静電防止の効果は図れる効果がある。しかし、この文献(3)は、セルロース系繊維スラリーを基材とした場合には、紙粉の剥離が問題となるが、この処理が十分でなく、使用の際に問題となる。一例を説明すると、搬送物に、紙粉が付着して埃の原因となること、またこの埃の剥離に作業、時間を要すること、又は処理手段、器具等を要すること、等の改良すべき問題がある。また搬送物の一部に不良品でも発生すれば、この不良品が無駄となること、また不良品の処理に基づく手間、二次公害、又は経済的な打撃となること、等の問題が発生する。
【0009】
【発明が解決しようとする課題】
前述の如く、文献(1)〜(3)においては、一長一短があり、車輌用の内装材としては、改良の余地があること、又は市井の要望、社会状況、環境、また部品・コストの削減等の要望に応えるためには、解決すべき課題が残っているのも現況である。
【0010】
上記に鑑み本発明は、固有抵抗値の大きな物質に発生した静電気は流れず蓄積帯電されることを考慮して、この帯電防止を図ること、又は除電にはアースが必要となり、しかも前記固有抵抗値の大きな物質により静電気が帯電すると、この帯電を減衰するのに多くの時間を要するが、本発明では、帯電発生を回避しつつ、かつ減衰に要する時間の短縮化を図ること、またアースは点ではなく、面により行うことが、極めて有益であること、等を意図する。また本発明は、固有抵抗値の大きな物質の表面における体積固有抵抗値を小さく改善して電気が流れやすくして帯電防止を図ること、廃棄処理に要する二次公害発生回避等の手間、又は設備を要さず簡易に廃棄処理ができる車輌用の内装材を提供すること、等を意図する。

【発明の実施の形態】
本発明の車輌用の内装材の中心をなす導電性シートの実施の形態を説明すると、図1に示すフローチャートの如く、解繊機、叩解機、又は撹拌混合機械、或いは粉砕混合機械等の手段(解繊機、叩解機とする)に、パルプ繊維及び/又はカーボン繊維等を投入し、当該パルプ繊維、カーボン繊維を、所定の寸法に叩解及び/又は撹拌・粉砕等する。この作業で、叩解及び/又は粉砕されたパルプ繊維、カーボン繊維でなる導電性の粒子(粉砕粒子とする)が生成される。この粉砕粒子に、水分を媒体として撥水又は耐水処理を行ない、水溶性の粉砕粒子とする(泥状化したパルプ素材、所謂、スラリーとする)。この工程において、水分を媒体として泥状化したパルプ素材とすることで、作業の効率化、簡略化等を図り、かつ確実で品質の良い泥状化したパルプ素材を生成できる。その後、この例では二つのルート(以下の[1]、[2])を辿る。この各ルートを個別に説明する。この水分の付与は、何れの方法でも可能であり、例えば、噴霧、充填、塗布等があり、簡便かつ確実な方法を採用する。
【0022】
[1] 第一のルート(ウェット成形ルート)は、抄製工程を経由して、紙抄きの感覚で導電性シートを作製する。この導電性シートを乾燥した後に(又は乾燥しつつ)、紙粉防止処理を行なう。この紙粉防止処理は、水分を媒体として泥状化したパルプ素材に、水溶性エマルジョン等の薬剤を、何れの方法で添加する。その添加は、例えば、噴霧、充填、塗布等があり、簡便かつ確実な方法を採用する。そして、この工程において、紙粉防止処理を行なうのは、乾燥工程により表面に噴き出た紙紛を確実に押えて、平面平滑性を確保できる。また後工程での紙紛落下と、この落下に基づくトラ ブルの解消と、又は作業の効率化、簡略化等を図り、かつ確実で品質の良い導電性シートの製造に役立つ特徴がある。尚、この紙粉防止処理は、後工程の例えば、積層及び/又は熱圧着工程においてロールプレス機等の熱プレスで、熱による圧着を利用し、略自然の状態で、前記紙紛の押え及び/又は平面平滑性が確保できるので、有益である。この工程の積層及び/又は熱圧着工程では、芯材として、例えば、牛乳パックの再生品、ダンボール芯、又は他の紙製芯材(再利用が図れ有益である)、 プラスチック芯材(再利用に少し問題であるが利用できる。但し、分解性プラスチックが理想である)を利用して、この芯材の少なくとも一面に導電性シートを添接する。勿論、図示しないが、導電性シートのみの積層も可能である。何れにしても、この導電性シートの枚数は一枚でも可能であるが、枚数が増加すればそれなりの除電効果は期待できる。また導電性シートを、一枚のみで利用できるが、強度、引張り等による破壊等を問題としない場合に有益である。この積層及び/又は熱圧着工程で製造された静電気除去防止構造体は、二つのルート(板紙成形ルート、ドライ成形ルート)がある。この板紙成形ルートは、トリミング加工を利用して不要部分を切断する。この切断後、エアー工程を利用して付着した塵、埃又は滓等を排除して完成品とする。またドライ成形ルートは、積層熱圧着の前後で分岐し、プレス成形機等によるプレス成形後、エアー工程を利用して付着した塵、埃又は滓等を排除して所定の形状の静電気除去防止構造体製品を製造する。
【0023】
[2] 第二のルート(ウェット成形ルート)は、抄製工程とともに成形し、紙抄きの感覚と成形とを一体に行ない、湿潤状態の導電性シート素材を作製する。この導電性シート素材に、紙粉防止処理を行なう方法であり、最も簡単な方法であり、大量生産、低コスト化等に寄与できる。この例の特徴も前述の例に準ずる。その後、芯材とともに熱プレス機等によるプレス成形で、所定の形状の静電気除去防止構造体製品を製造する。他の構成及び/又は特徴は前述の例に準ずる。
【0024】
この導電性シートを中心として、図3〜図6に示した車輌用硬性の内装材と、また図7〜図10に示した車輌用クッション性の内装材を構成する。先ず、図3〜図6の一例における車輌用硬性の内装材を説明すると、図3、図4に示した例では、帯電防止機能を備えた表皮材と、成形紙材と、導電性シートとを順次積層した後に、熱プレス機等によるプレス成形で、所定の形状に成形することで少なくとも表面部及び裏面部に空中放電機能を有する三層構造の帯電防止機能を備えた車輌用硬性の内装材が製造できる。また図5、図6に示した例では、帯電防止機能を備えた表皮材と、表裏(上下側)に導電性接着剤を備えた(導電性フィルムラミネートした)成形紙材と、導電性シートとを順次積層した後に、熱プレス機等によるプレス成形で、所定の形状に成形することで少なくとも表面部及び中間部並びに裏面部に放電機能を有する三層構造の帯電防止機能を備えた車輌用硬性の内装材が製造できる。次に、図7〜図10の一例における車輌用クッション性の内装材を説明すると、図7、図8に示した例では、帯電防止機能を備えた表皮材と、成形紙材又はクッション材と、導電性シートとを順次積層した後に、熱プレス機等によるプレス成形で、所定の形状に成形することで少なくとも表面部及び裏面部に放電機能を有する四層構造の帯電防止機能を備えた車輌用硬性の内装材が製造できる。また図9、図10に示した例では、帯電防止機能を備えた表皮材と、表裏に導電性接着剤を備えた(導電性フィルムラミネートした)成形紙材又はクッション材と、導電性シートとを順次積層した後に、熱プレス機等によるプレス成形で、所定の形状に成形することで少なくとも表面部及び中間部並びに裏面部に放電機能を有する四層構造の帯電防止機能を備えた車輌用硬性の内装材が製造できる。

The present invention relates to a vehicle interior material having an antistatic function.
[0002]
[Prior art]
As is well known, static electricity is generated in all materials by friction. In addition, in human charging, for example, it may vary depending on weather conditions, surrounding environment (clothes to be worn, material of clothes, or constitution), or there may be a strong sense of incongruity depending on the person, and there is a risk of injury. In addition, there is a problem that it is very unpleasant because it receives a strong impact. Such inconvenience due to electrification is more serious in the vehicle intended by the present invention because a part of the vehicle body plays a role as a conductor. For example, it is an unavoidable problem for drivers, passengers, and the like. It is.
[0003]
Because of the above disadvantages, generally, means for removing static electricity from the vehicle body is employed. For example, there are parts for earthing (forcibly attenuated by earthing), earth goods, etc., some of which are put to practical use. However, this kind of static electricity removing means is troublesome to install, etc., needs to be replaced due to wear, adverse effects due to dust (although slight), or in a dry state, etc. The current situation is that it is not so popular.
[0004]
As inventions that essentially improve the above problems, inventions relating to surface materials (skin materials) having an antistatic function, interior materials, etc. are often found in vehicle seats, bodies, interior materials, and the like. Some of them will be described as documents, which are the following document (1) and document (2).

DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the conductive sheet forming the center of the vehicle interior material of the present invention will be described. As shown in the flowchart of FIG. 1, means such as a defibrator, a beating machine, a stirring and mixing machine, or a pulverizing and mixing machine ( Pulp fibers and / or carbon fibers and the like are put into a defibrator and beating machine, and the pulp fibers and carbon fibers are beaten and / or stirred and pulverized to a predetermined size. In this operation, conductive particles (referred to as pulverized particles) made of beaten and / or pulverized pulp fibers and carbon fibers are generated. The pulverized particles are subjected to water repellency or water resistance treatment using moisture as a medium to form water-soluble pulverized particles (a muddy pulp material, so-called slurry). In this step, by making the pulp material muddy using moisture as a medium, the efficiency and simplification of the operation can be achieved, and a reliable and high-quality muddy pulp material can be generated. Thereafter, in this example, two routes ([1] and [2] below) are followed. Each of these routes will be described individually. The application of moisture can be performed by any method, for example, spraying, filling, coating, etc., and a simple and reliable method is adopted.
[0022]
[1] In the first route (wet forming route), a conductive sheet is produced through a paper making process as if paper making. After the conductive sheet is dried (or dried), paper dust prevention treatment is performed. In this paper dust prevention treatment, a chemical such as a water-soluble emulsion is added by any method to a pulp material made muddy with water as a medium. The addition includes, for example, spraying, filling, and application, and a simple and reliable method is adopted. In this step, the paper dust prevention treatment can surely press the paper dust sprayed on the surface by the drying step, and ensure the planar smoothness. In addition, there are features that are useful for producing reliable and high-quality conductive sheets by eliminating paper dust in the subsequent process, eliminating troubles based on this drop, and improving work efficiency and simplification. In addition, this paper dust prevention treatment uses a heat press such as a roll press machine in a subsequent process, for example, a lamination and / or thermocompression bonding process, and uses pressure bonding by heat, in a substantially natural state, This is advantageous because the planar smoothness can be ensured. In the lamination and / or thermocompression process of this process, as a core material, for example, a recycled product of a milk pack, a corrugated cardboard core or other paper core material (useful for reuse), a plastic core material (for reuse) A conductive sheet is attached to at least one surface of the core material using a degradable plastic, although it is a little problematic. Of course, although not shown, it is possible to stack only conductive sheets. In any case, the number of conductive sheets can be one, but if the number of sheets increases, a reasonable charge removal effect can be expected. In addition, the conductive sheet can be used by only one sheet, but it is useful when there is no problem of breakage due to strength, tension or the like. The static electricity removal prevention structure manufactured by this lamination and / or thermocompression bonding process has two routes (a paperboard forming route and a dry forming route). This paperboard forming route cuts unnecessary portions using trimming. After this cutting, the dust, dust, soot, etc. adhering using an air process are removed and it is set as a finished product. The dry molding route branches before and after the laminated thermocompression bonding, and after press molding with a press molding machine etc., dust, dust or soot that adheres using an air process is removed to prevent static electricity removal of a predetermined shape Manufacture body products.
[0023]
[2] The second route (wet forming route) is formed together with the paper making process, and the paper making sensation and forming are integrated to produce a wet conductive sheet material. This is a method for carrying out paper dust prevention treatment on this conductive sheet material, which is the simplest method and can contribute to mass production and cost reduction. The characteristics of this example are also the same as those described above. Then, the static elimination prevention structural body product of a predetermined shape is manufactured by press molding with a hot press machine etc. with a core material. Other configurations and / or features are similar to those described above.
