好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。   An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

例えば事故現場で流出した油を処理する場合、この油が流出した部位に本発明に係る油吸着体を配し、油を吸着する。面状基体１は繊維１ａで構成されており秀れた油吸着性能を具備する。   For example, when processing the oil spilled at the accident site, the oil adsorbent according to the present invention is disposed at the site where the oil spills, and the oil is adsorbed. The planar substrate 1 is composed of fibers 1a and has excellent oil adsorption performance.

ところで、本発明は、繊維１ａで構成される面状基体１の表面に導電部材２が設けられているから、面状基体１は静電気防止性を具備し、従って、油が静電気により着火する静電気火災が起きる心配はなく極めて有用である。   By the way, in the present invention, since the conductive member 2 is provided on the surface of the planar substrate 1 composed of the fibers 1a, the planar substrate 1 has antistatic properties, and therefore, static electricity in which oil is ignited by static electricity. There is no fear of fire and it is extremely useful.

本発明の具体的な一実施例について図面に基づいて説明する。   A specific embodiment of the present invention will be described with reference to the drawings.

本実施例は、油を吸着せしめる油吸着体４であって、繊維１ａで構成される面状基体１の表面に導電部材２が設けられたものである。   The present embodiment is an oil adsorbing body 4 that adsorbs oil, and a conductive member 2 is provided on the surface of a planar substrate 1 composed of fibers 1a.

以下、本実施例に係る構成各部について詳細な説明をする。   Hereinafter, each component according to the present embodiment will be described in detail.

面状基体１は、化学繊維１ａ（合成繊維）で構成される不織布であり、本実施例ではポリプロピレン製の不織布としている。尚、不織布は天然繊維（例えばセルロース）で構成しても良いなど本実施例の特性を発揮する構成であれば適宜採用し得るものである。また、面状基体１は不織布に限らず織布でも良い。   The planar substrate 1 is a non-woven fabric composed of chemical fibers 1a (synthetic fibers), and is a non-woven fabric made of polypropylene in this embodiment. In addition, if a structure which exhibits the characteristic of a present Example, a nonwoven fabric may be comprised with natural fiber (for example, cellulose), it can employ | adopt suitably. Further, the planar substrate 1 is not limited to a nonwoven fabric but may be a woven fabric.

導電部材２は、粉状若しくは粒状とした籾殻炭（炭）であり、この籾殻炭は、導電性を具備し、また、多孔質であるため油吸着機能も具備する。尚、導電部材２としては籾殻炭（炭）に限られるものではなく、本実施例の特性を発揮する構成であれば適宜採用し得るものである。   The conductive member 2 is powdered or granular rice husk charcoal (charcoal), and this rice husk charcoal has conductivity and also has an oil adsorption function because it is porous. Note that the conductive member 2 is not limited to rice husk charcoal (charcoal), and any structure that exhibits the characteristics of the present embodiment can be used as appropriate.

この導電部材２を面状基体１の表面に塗布する場合には、図２に図示したように面状基体１の表面にスプレー糊７を塗布し、続いて、粉状の導電部材２を面状基体１の表面全体に配し（散布し）、糊７が固化することで定着して油吸着体４が完成する。   When this conductive member 2 is applied to the surface of the planar substrate 1, spray paste 7 is applied to the surface of the planar substrate 1 as shown in FIG. The oil adsorbent 4 is completed by spreading (spreading) the entire surface of the substrate 1 and solidifying the glue 7.

ところで、本実施例では、面状基体１の電気表面抵抗は１×１０12Ω／平方（□）よりも低い値に設定されている。尚、物質表面に静電気が帯電するかしないかの境界域は１×１０12Ω／□であり、１×１０12Ω／□以上であれば帯電し、未満であれば帯電しない。 By the way, in this embodiment, the electric surface resistance of the planar substrate 1 is set to a value lower than 1 × 10 12 Ω / square (□). In addition, the boundary area of whether or not static electricity is charged on the surface of the material is 1 × 10 12 Ω / □, and if it is 1 × 10 12 Ω / □ or more, it is charged, and if it is less, it is not charged.

具体的には、前述したように面状基体１の表面に粉状の籾殻炭から成る導電部材２を散布するにあたり、この導電部材２を、面状基体１の表面積５０ｍｍ×５０ｍｍあたり０．０１ｇ以上を散布しており、このようにして得られた油吸着体４の電気表面抵抗は、１×１０12Ω／□よりも低い値となり、静電気防止機能を具備することになる。 Specifically, as described above, when the conductive member 2 made of powdered rice husk charcoal is sprayed on the surface of the planar substrate 1, the conductive member 2 is 0.01 g per 50 mm × 50 mm surface area of the planar substrate 1. The electric surface resistance of the oil adsorbent 4 obtained in this way is lower than 1 × 10 12 Ω / □ and has an antistatic function.

この点については本発明者が行った試験により確認している。   This point has been confirmed by a test conducted by the present inventors.

即ち、図４に図示したように５０ｍｍ×５０ｍｍの表面積を有する面状基体１を３枚用意し、前述したように面状基体１の表面にスプレー糊７を塗布した後に０．０１ｇの導電部材２（微粉籾殻炭）を散布した試験体Ａを作出し、面状基体１の表面にスプレー糊７を塗布した後に０．０３ｇの導電部材２（微粉籾殻炭）を散布した試験体Ｂを作出し、面状基体１の表面にスプレー糊７を塗布した後に０．０５ｇの導電部材２（微粉籾殻炭）を散布した試験体Ｃを作出し、各試験体Ａ，Ｂ，Ｃ夫々の電気表面抵抗を測定した。   That is, as shown in FIG. 4, three planar substrates 1 having a surface area of 50 mm × 50 mm are prepared, and after applying the spray paste 7 on the surface of the planar substrate 1 as described above, 0.01 g of conductive member 2 (sprayed rice husk charcoal) was produced, and after applying paste 7 to the surface of the planar substrate 1, 0.03 g of conductive member 2 (fine husk charcoal) was produced. Then, after applying the spray paste 7 to the surface of the planar substrate 1, a test body C in which 0.05 g of the conductive member 2 (fine husk husk charcoal) was sprayed was produced, and the electrical surface of each of the test bodies A, B, C Resistance was measured.

その結果、試験体Ａの電気表面抵抗は１．４×１０11Ω／□であり、試験体Ｂの電気表面抵抗は１．３×１０10Ω／□であり、試験体Ｃの電気表面抵抗は４．１×１０9Ω／□であり、いずれも電気表面抵抗が１×１０12Ω／□よりも低く、帯電しない電気表面抵抗とされる値が出た。 As a result, the electrical surface resistance of the test body A is 1.4 × 10 11 Ω / □, the electrical surface resistance of the test body B is 1.3 × 10 10 Ω / □, and the electrical surface resistance of the test body C Was 4.1 × 10 9 Ω / □, and the electric surface resistance of each was lower than 1 × 10 12 Ω / □, and a value that was regarded as an uncharged electric surface resistance was obtained.

従って、この結果を基に、本実施例は、導電部材２を、面状基体１の表面積５０ｍｍ×５０ｍｍあたり０．０１ｇ以上を散布しており、必要量の導電部材２が散布されて面状基体１は帯電防止性を有しているため、油が静電気により着火する静電気火災が起きる心配はなく、しかも、必要最低限の量の導電部材２を使用することで面状基体１の油吸着性能に支障なく、コスト安であるなど極めて有用である。   Therefore, based on this result, in the present embodiment, the conductive member 2 is sprayed over 0.01 g per surface area 50 mm × 50 mm of the planar substrate 1, and a necessary amount of the conductive member 2 is sprayed into the planar shape. Since the substrate 1 has antistatic properties, there is no fear of an electrostatic fire in which the oil is ignited by static electricity, and the oil adsorption of the planar substrate 1 is achieved by using the minimum amount of the conductive member 2. It is extremely useful because it does not hinder performance and is low in cost.

また、本実施例に係る油吸着体は、図１に図示したように適宜な脱酸素剤５（例えば三菱ガス化学株式会社製のエージレス（登録商標））及び適宜な乾燥剤６（例えばＡＧＣエスアイテック株式会社製のヒシビート（商品名））とともに通気しない容体３内に収納し、容体３内の空気を抜いた後に密閉することで保存される。   Further, as shown in FIG. 1, the oil adsorbent according to the present embodiment includes an appropriate oxygen scavenger 5 (for example, Ageless (registered trademark) manufactured by Mitsubishi Gas Chemical Co., Ltd.) and an appropriate desiccant 6 (for example, AGC ES). It is stored in a container 3 that does not vent together with Hishibeat (trade name) manufactured by ITEC Co., Ltd., and is stored by sealing after removing the air in the container 3.

容体３は、通気性を具備しない部材（合成樹脂や金属など）からなる袋（例えば株式会社メイワパックス製のバリアナイロン／ポリエチレンからなる袋、ポリエチレンテフタレート／アルミ／ポリエチレンからなる袋）であり、開口部から油吸着体４と脱酸素剤５と乾燥剤６を収納した後、開口部がシール（熱融着）される。この容体３の開口部を閉塞する際、場合によっては脱酸素剤５及び乾燥剤６を収納せず単に密閉するだけでも良いし、容体３内を完全に真空処理しても良いし、不活性ガスを充填するようにしても良い。   The container 3 is a bag (for example, a bag made of barrier nylon / polyethylene, a bag made of polyethylene terephthalate / aluminum / polyethylene manufactured by Meiwa Packs Co., Ltd.) made of a member that does not have air permeability (synthetic resin, metal, etc.). After storing the oil adsorbent 4, the oxygen scavenger 5 and the desiccant 6 from the opening, the opening is sealed (heat-sealed). When the opening of the container 3 is closed, the oxygen scavenger 5 and the desiccant 6 may not be stored in some cases, and the container 3 may be simply sealed, or the interior of the container 3 may be completely vacuumed, or inert. You may make it fill with gas.

尚、容体３は袋に限らず箱状体でも良い。   The container 3 is not limited to a bag but may be a box-shaped body.

この保存方法から、脱酸素剤５及び乾燥剤６の機能により油吸着体４の良好な長期保存が可能となり（例えば時間の経過と共に湿気等で含水率が多くならないようにする保存が可能となる）、いつでも容体３から出した際には良好な機能を発揮することができる良好な保存状態が得られることになる。   From this storage method, the function of the oxygen scavenger 5 and the desiccant 6 enables good long-term storage of the oil adsorbent 4 (for example, storage can be performed so that the moisture content does not increase due to moisture or the like over time. ) When the battery is taken out of the container 3 at any time, a good storage state capable of exhibiting a good function can be obtained.

また、容体３は帯電防止性を有している。前述した素材は油が着火する程度の静電気が帯電しないことは確認済みである。   The container 3 has antistatic properties. It has been confirmed that the above-mentioned materials are not charged with static electricity enough to ignite oil.

例えば油を吸着する場面（例えば事故現場やガソリンスタンドなど）において、吸着しようとする油が、現場に持ち込んだ部材に帯電した静電気により着火することが危惧される。   For example, in a scene where oil is adsorbed (for example, an accident site or a gas station), there is a concern that the oil to be adsorbed may be ignited by static electricity charged on a member brought to the site.

この点、本実施例は、容体３は帯電防止性を具備しているため、油が静電気により着火する静電気火災が起きる心配はなく極めて有用である。   In this respect, this embodiment is extremely useful because there is no fear of an electrostatic fire in which the oil is ignited by static electricity because the container 3 has antistatic properties.

本実施例は上述のように構成したから、例えば事故現場で流出した油を処理する場合、この油が流出した部位に本実施例に係る油吸着体４を配し、油を吸着する。面状基体１は繊維１ａで構成されており秀れた油吸着性能を具備する。   Since the present embodiment is configured as described above, for example, when oil spilled at the accident site is processed, the oil adsorbing body 4 according to the present embodiment is arranged at a portion where the oil spills to adsorb the oil. The planar substrate 1 is composed of fibers 1a and has excellent oil adsorption performance.

繊維１ａで構成される面状基体１の表面には導電部材２が散在されており、よって、面状基体１は静電気防止性を具備しているため、油が静電気により着火する静電気火災が起きる心配はなく極めて有用である。   Conductive members 2 are interspersed on the surface of the planar substrate 1 composed of the fibers 1a. Therefore, the planar substrate 1 has antistatic properties, and an electrostatic fire in which oil is ignited by static electricity occurs. There is no worry and it is extremely useful.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。   Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
