Description

本発明は、クリンルーム等の入口付近の床面に置いて、クリーンルーム入室者の履物に付着したチリや泥等の飛散や進入を防止する異物吸着シートに関するものである。   The present invention relates to a foreign matter adsorbing sheet that is placed on a floor near an entrance of a clean room or the like and prevents dust and mud adhering to footwear of clean room occupants from entering and scattering.

従来より、精密部品等を製造する室内は常にクリーンな状態を保つために、チリや綿埃等を吸引排除する精密なエヤーコンディショナー等により室内空気清浄を行っている。一方、この入口に置いてはエヤーシャワー等により衣服等に付着したチリや綿埃の除去と共に、入室者の履物の裏側のチリや泥等の異物をとる粘着シートが知られている。   Conventionally, in order to maintain a clean room in which precision parts and the like are always kept clean, indoor air is cleaned with a precision air conditioner that sucks and removes dust and cotton dust. On the other hand, there is known an adhesive sheet that is placed at the entrance to remove foreign matter such as dust and mud on the back side of the footwear of the occupant while removing dust and cotton dust adhering to clothes by an air shower or the like.

従来の異物粘着シートは図5に示すように、樹脂シート等の基材シート11上に粘着剤(15)を塗布した粘着シート(30)であり、必ずこのシート上を歩いてチリや泥を落とすようにしてクリーンルーム内にこれらの異物(t)を持ち込まないようにしたものである。また、この裏面には固定のための接着剤等を設けたものが一般的であり、この表面の異物を付着させる粘着剤の効果が劣化した場合には、その都度床から剥がして粘着シート毎交換する必要があった。これに対して、フィルムの外表面がフィルム自体であって、しかも高い帯電防止性能を長く持続することのできる素材が開発されている。   As shown in FIG. 5, the conventional foreign material pressure-sensitive adhesive sheet is a pressure-sensitive adhesive sheet (30) obtained by applying a pressure-sensitive adhesive (15) on a base material sheet 11 such as a resin sheet. The foreign matter (t) is not brought into the clean room by dropping it. In addition, the back side is generally provided with an adhesive or the like for fixing, and when the effect of the pressure-sensitive adhesive for adhering foreign matter on the surface is deteriorated, the adhesive sheet is peeled off from the floor each time. It was necessary to replace it. On the other hand, a material has been developed in which the outer surface of the film is the film itself and the antistatic performance can be maintained for a long time.

特開平7−252456号公報(特許文献1)によれば、静電誘導防止性を有する架橋性重合体からなる接着プライマー、及び該プライマー層を有する積層フィルムが提案されると共に実用化されている。すなわち、プラスチックフィルム外表面の静電気発生を抑止し、包装材料、情報記録材料、建築材料、印刷材料、電子材料等の多くの静電気障害を問題とする分野に有効な材料である。   According to Japanese Patent Laid-Open No. 7-252456 (Patent Document 1), an adhesion primer made of a crosslinkable polymer having electrostatic induction preventing properties and a laminated film having the primer layer are proposed and put into practical use. . That is, it is an effective material in the field where many static electricity obstacles such as packaging materials, information recording materials, building materials, printing materials, electronic materials, and the like are suppressed by generating static electricity on the outer surface of the plastic film.

この積層フィルムの活用を挙げるならば、粘着シートではなく包装材料であるが、帯電防止剤として従来使用されてきた界面活性剤を使用せずに、静電気の帯電を有効に防止することができる帯電防止性包装材料が提案されている。   If this laminated film is used, it is a packaging material, not an adhesive sheet, but it can be used to effectively prevent static charges without using a surfactant that has been used as an antistatic agent. Preventive packaging materials have been proposed.

特開平9−24572号公報(特許文献2)によれば、基材上に設けた帯電防止層とからなる帯電防止性包装材料であり、さらに前記帯電防止層上にシーラント層を形成した包装材料である。従って、包装材料表面の帯電を防止できると共に、その裏面に静電誘導により帯電が生ずることを防止する包装材が提案されている。   According to Japanese Patent Laid-Open No. 9-24572 (Patent Document 2), an antistatic packaging material comprising an antistatic layer provided on a base material, and a packaging material having a sealant layer formed on the antistatic layer. It is. Accordingly, there has been proposed a packaging material that can prevent the surface of the packaging material from being charged and prevent the back surface from being charged by electrostatic induction.

先に述べたように、粘着シート(30)は新しい内は表面の粘着剤(15)に履物の底に着いた泥、チリ等の異物(t)を良く取る(粘着させる)ことができるが、これらの異物が溜まり粘着性が劣化すると取ることが難しくなる。また、靴などの履物の周囲や底に着いた異物は、履物の底が粘着シートを離れるときに剥離帯電による静電気が発生し空中に異物が飛んだり、また、異物自体の静電気で付着した異物も取り除くことが難しい問題もあった。さらに、衣服に着いたチリ等はエアーシャワーにより落とされるがチリ自体が
帯電しており、粘着シートだけでは付着させることができない等の問題があり、絶えず新品の粘着シートと交換する必要があり、経済的にも無駄が多かった。
As described above, the pressure-sensitive adhesive sheet (30) can remove (adhere) foreign matter (t) such as mud and dust attached to the bottom of the footwear well on the surface pressure-sensitive adhesive (15). When these foreign substances accumulate and the adhesiveness deteriorates, it becomes difficult to remove. In addition, foreign matter attached to the periphery or the bottom of footwear, such as shoes, is generated by static electricity due to peeling electrification when the bottom of the footwear leaves the adhesive sheet. There were also problems that were difficult to remove. In addition, dust that has been worn on clothes is dropped by the air shower, but the dust itself is charged, and there is a problem that it can not be attached only with the adhesive sheet, and it is necessary to constantly replace it with a new adhesive sheet, It was economically wasteful.

そこで本発明は、上記の問題を解決するためになされたもので、クリンルーム等の入口付近の床面に置いて、チリや履物の泥等の異物の進入を防止する静電誘導防止層を設けた異物吸着シートを提供するものである。   Therefore, the present invention has been made to solve the above problems, and an electrostatic induction prevention layer is provided on the floor surface near the entrance of a clean room or the like to prevent entry of foreign matters such as dirt and footwear mud. The provided foreign matter adsorbing sheet is provided.

本発明の請求項1に係る発明は、

The invention according to claim 2 of the present invention is
An electrostatic induction preventing layer (12) is provided on the back surface of the base material sheet (11) made of polyethylene terephthalate or the like, and an adhesive layer (15) is provided on the front surface side of the base material sheet (11). It is a foreign matter adsorbing sheet.

本発明は、ポリエチレンテレフタレート等からなる基材シート上に、静電誘導防止層と粘着剤層とを積層してなる構成を特徴とするものである。従って、従来における靴などの履物の周囲や底に着いた異物や、履物の底が粘着シートを離れるときに剥離帯電による静電気の発生による異物が飛んだり等の、帯電したチリやゴミも取り除くことができる異物吸着シートを得ることができる。またこれらのチリ等を取り除く効果は長続きするので、吸着効果の劣化が遅くなり交換頻度が減少し、経済的に無駄を省くことが可能である。   The present invention is characterized by a structure in which an electrostatic induction preventing layer and an adhesive layer are laminated on a base material sheet made of polyethylene terephthalate or the like. Therefore, remove any dust or dirt that has been charged, such as foreign objects that have adhered to or around the footwear, such as conventional shoes, or foreign objects that have been generated due to the generation of static electricity due to peeling electrification when the footwear leaves the adhesive sheet. It is possible to obtain a foreign matter adsorbing sheet that can be used. In addition, since the effect of removing dust and the like lasts for a long time, the deterioration of the adsorption effect is delayed, the replacement frequency is reduced, and waste can be saved economically.
