Abstract

<P>PROBLEM TO BE SOLVED: To lengthen a carry; and to enhance controllability of throwing by allowing the throwing to an objective place in a state of folding up or rounding a mat. <P>SOLUTION: A water absorptive expandable tube is installed along the outer peripheral edge of the oil adsorbing mat. Thus, the mat is rounded in an unspecified shape, and can be thrown by binding by a water soluble binding material. The mat can be thrown to a further distant place more than a conventional mat, and the throwing direction and a throwing distance can be precisely controlled. Since the binding material for binding the oil adsorbing mat is water soluble, binding is quickly released after landing on the water, and as a result of expanding a water expandable tube installed along the outer peripheral edge of the oil adsorbing mat by absorbing water, the oil adsorbing mat is quickly and flatly restored, and can start adsorption of oil. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
本発明は、例えば河川や湖沼、あるいは海洋に流出した重油その他の油を回収するための油回収材に関し、吸油能力の向上をはかるとともに投擲の安定性および着水後の迅速な復元を可能にし、これによって十分な飛距離の確保、ならびに直線的飛行を可能にして河川敷や湖岸、あるいは船上などからの目的箇所への正確な投擲を可能にし、油回収効率と作業の安全性を向上させることを目的とする。
【0002】
【従来の技術】
投擲用として従来一般的に汎用されている油吸着材は、不織布などを用いた厚さが4〜5mm程度の油吸着マットを四角平盤状にして重量を凡そ100g程度に構成したものが知られている。
【0003】
【発明が解決しようとする課題】
しかしながら、上記した汎用のものは油の吸着能力が十分ではなく、また水面上において次第に水をも吸着して時間の経過とともに水中に沈降することが多いために、油の回収における作業効率の面において問題があった。 またそればかりでなく、比較的柔軟で保形成に劣るところから、投擲に際して形状が不安定となり、投擲方向や距離のコントロールが難しく、したがって目的箇所への適格な投擲がきわめて困難である。
【0004】
【課題を解決するための手段】
そこで本発明は、油吸着マットを折り畳み、あるいは丸め、その状態のまま紙紐、や水溶性ポリマーのテープなどの水溶性結束材により結束し、また保管することにより、投擲使用に際して、より遠くに、しかも投擲方向や距離の適確なコントロールを可能にして投げやすくするとともに、着水後速やかな復元を可能にしたものであって、具体的には請求項1の発明は、油吸着マットの外周端縁に沿って吸水膨張性のチューブを取り付けてなることを特徴としたポリマーチューブ式投擲用油吸着マットに関する。
【0005】
また請求項2の発明は、外周端縁に沿って吸水膨張性のチューブを取り付けてなる油吸着マットを折り畳み或いは丸めたままの状態で水溶性の結束材にて結束してなるポリマーチューブ式投擲用油吸着マットに関する。 さらに請求項3の発明は、油吸着マットが、重合させた二枚の親油性繊維の間に吸油性粉末ゲル化剤マットを介在させて積層体としたものであるところの請求項1又は請求項2に記載のポリマーチューブ式投擲用油吸着マットに関する。 さらに請求項4の発明は、油吸着マットが多数のゲル化剤ポケットを有するとともに、各ゲル化剤ポケット内にはゲル化剤が充填されているものであるところの請求項1又は請求項2に記載のポリマーチューブ式投擲用油吸着マットに関する。
【0006】
上記の構成において、油吸着マットを折り畳み、あるいは丸めた状態のまま紙紐や水溶性ポリマーのテープなどの水溶性結束材により結束したままの状態において保管し、また使用時においてはそのままの状態において目的箇所に向けて投擲する。 投擲された油吸着マットは目的水面上に落下後、水溶性結束材が水に溶解するとともに、吸水膨張性のチューブが吸水して直線状に膨張し、これに伴って油吸着マットが水面上に平板状に復元展張され、直ちに油の吸着を開始する。
【0007】
【発明の実施の形態】
以下において、本発明の具体的な内容を図1〜3の実施例をもとに説明すると、図において1は油吸着マット、3は吸水膨張性のチューブを示す。 ここで使用される油吸着マット1は、油を吸収する能力のある材質のものである必要があり、一般的には不織布が用いられ、さらに具体的には一定の厚みを有するポリプロピレン繊維が、ガソリンや灯油、あるいは軽油、A重油などの軽質油類を特に吸着しやすいので好ましい。
【0008】
油吸着マット1としては、例えば三井化学株式会社の発売する、商品名「タフネルPH−50」の使用が考えられる。 またこのほかにも、東レファインケミカル株式会社の発売する、商品名「ウォセップ」や、九州フィルター工業株式会社の発売する、商品名「KFO」、あるいは米国ナショナルソルベント社の、「MAXXJ−50」などの使用が考えられる。
【0009】
またこの場合の油吸着マット1の厚みについては、水面上において流失油をある程度吸着できる程度の厚みを有することが必要であり、そのためには厚さが3mm以下では油吸着が十分ではなく、少なくとも4mm以上の厚みを有する必要がある。 しかし厚さが8mmを超えると全体の厚みが厚くなりすぎて投擲に際して障害となることから4mm〜8mmの範囲内である必要がある。
【0010】
また油吸着マット1の大きさについても、直径が450mm未満では油吸着が十分ではないばかりでなく、投擲に不向きとなる。 また反対に900mmを超えると、やはり投擲し難くなるところから直径が450mm以上900mm以内である必要がある。
【0011】
さらに、油吸着マット1には多数のゲル化剤ポケット2が設けられているとともに、各ゲル化剤ポケット2内には吸油性のゲル化剤(図示省略)が充填される。 ここで使用される吸油性粉末ゲル化剤の具体例を挙げれば、ポリスチレンブロック相をポリマーの両端に有するポリスチレン・ポリブタジェンブロックポリマーの、スチレンとブタジェンの構成比が、1つはスチレン:20(重量)部以下、ブタジェン:80(重量)部以上、他の1つは、スチレン:40(重量)部以上、ブタジェン:60(重量)部以下の構成比を持ち、分子量が共に5×10以上の2成分からなる粉末ゲル化剤が使用できる。
【0012】
またこのほかにも、ポリスチレンブロック相をポリマーの両端に持ち、1つはポリスチレン・ポリブタジェンブロックポリマーの、スチレンとブタジェンの構成比が、スチレン:20〜40(重量)部、ブタジェン:60〜80(重量)部に、他の1つは、ポリスチレン・ポリエチレン/ブチレンブロックポリマーの、スチレン:25〜35(重量)部、エチレン/ブチレン:65〜75(重量)部、の構成を持つ2成分からなる粉末ゲル化剤が使用できる。
【0013】
上記した吸油性粉末ゲル化剤の使用としては、例えば、株式会社アルファジャパンの発売にかかる、商品名「アルファゲルマット」の使用が好ましい。 さらに油吸着マット1として特に図示はしないが、二枚の不織布のような親油性繊維の間に吸油性粉末ゲル化剤マットを介在させて積層体としたものを用いてもよい。
【0014】
さらに油吸着マット1の外周端縁に沿って取りつけられる吸水膨張性のチューブ3については、吸水して膨張し、折り畳み、あるいは丸められた油吸着マット1を平坦状に復元させることができる材料であればその内容については格別問わないが、具体例を挙げれば直径約5〜10ミリメートル程度のたとえば不織布のような水透過性のチューブ内に水溶性のポリマー粉末を充填して使用すると、ポリマーが水を吸水した場合に約30〜50倍程度に膨張して、折り畳まれ、あるいは丸められた油吸着マット1を平坦に復元させることができる。
【0015】
さらに、折り畳み、あるいは丸められた油吸着マット1を結束するための水溶性結束材としては、例えば紙紐や紙テープ、又は水溶性ポバールなどのPVA(ポリビニールアルコール)系のフィルム類、あるいは天然高分子系・半合成高分子系・合成高分子系などの水溶性フィルム類の使用などが考えられる。
【0016】
本発明は上記の構成において、油吸着マット1を二つ折りあるいは四つ折りに折り畳み、あるいは丸め、その状態のまま紙紐や水溶性ポリマーのテープなどの水溶性結束材(図示省略)により結束し、また結束した状態のまま保管し、使用時にはそのまま水面上の目的箇所に向けて投擲する。 水面上に落下した球状や塊状の油吸着マット1は、水溶性結束材が水に溶解して結束が解かれるとともに、吸水膨張性のチューブ3が吸水して直線状に膨張(図3参照)し、これに伴って油吸着マット1が水面上に平板状に速やかに復元展張される。 水面上に平板状に復元展張された油吸着マット1は油の吸着を開始し、吸着した油は油吸着マット1および多数のゲル化剤ポケット2内のゲル化剤に吸収される。
【0017】
【発明の効果】
本発明は上記した通り、外周端縁に沿って吸水膨張性のチューブを取り付けた油吸着マットを折り畳み、あるいは球状に丸めたまま水溶性の結束材にて結束してなるポリマーチューブ式投擲用油吸着マットであるために、マットを不特定形状に丸めて水溶性結束材により結束して投擲することができ、従来品に比べてより一層遠くに投げることができ、しかも投擲方向や投擲距離の適確なコントロールが可能となる。
【0018】
また油吸着マットを結束する結束材が水溶性であるために、着水後速やかに結束が解かれ、しかも油吸着マットの外周端縁に沿って取りつけた吸水膨張性のチューブが吸水して膨張する結果、油吸着マットが速やかに平坦に復元し、油の吸着を開始することができる。
【0019】
さらに油吸着マットが、重合させた二枚の親油性繊維の間に吸油性粉末ゲル化剤マットを介在させて積層体としたために、ゲル化剤の浮力により、投擲した後水面上において長時間にわたり沈降することがなく、しかも親油性繊維の吸着した過剰な油が吸油性粉末ゲル化剤マットの吸油性粉末ゲル化剤によりゲル化され、油の再流失を防ぐことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an oil recovery material for recovering heavy oil or other oil spilled into, for example, rivers, lakes and marshes, or the ocean, and aims to improve the oil absorption capacity and enable the stability of throwing and rapid restoration after landing. , Thereby ensuring a sufficient flight distance and enabling straight-line flight, enabling accurate throwing from a riverbed, lake shore, or on board to a target location, improving oil recovery efficiency and work safety. With the goal.
[0002]
[Prior art]
An oil adsorbent conventionally and generally used for throwing is an oil adsorbent made of a nonwoven fabric or the like and having a thickness of about 4 to 5 mm, and is formed in a square flat plate shape to have a weight of about 100 g. Have been.
[0003]
[Problems to be solved by the invention]
However, the above-mentioned general-purpose type does not have a sufficient oil-absorbing ability, and also often adsorbs water on the water surface and settles in the water over time. Had problems. In addition, since it is relatively flexible and inferior in shape, the shape becomes unstable when throwing, it is difficult to control the throwing direction and distance, and it is extremely difficult to properly throw it at a target location.
[0004]
[Means for Solving the Problems]
Therefore, the present invention folds or rounds the oil-absorbing mat, ties it with a water-soluble tying material such as a paper string or a water-soluble polymer tape in that state, and stores it, so that it can be used farther in throwing use. In addition, it enables accurate control of the throwing direction and distance to facilitate throwing, and enables quick restoration after landing. Specifically, the invention of claim 1 relates to an oil absorbing mat. The present invention relates to a polymer tube type oil-absorbing mat for throwing, wherein a water-swellable tube is attached along the outer peripheral edge.
[0005]
Further, the invention according to claim 2 is a polymer tube-type throwing device in which an oil-absorbing mat having a water-absorbing expandable tube attached along an outer peripheral edge is bound with a water-soluble binding material in a state of being folded or rolled. The present invention relates to an oil absorption mat for use. Further, the invention of claim 3 is the oil absorption mat according to claim 1 or claim, wherein the oil-adsorbing mat is a laminate in which an oil-absorbing powder gelling agent mat is interposed between two polymerized lipophilic fibers. Item 2 relates to a polymer tube type oil-absorbing mat for throwing according to Item 2. Further, in the invention of claim 4, the oil adsorbing mat has a plurality of gelling agent pockets, and each gelling agent pocket is filled with a gelling agent. And a polymer tube type oil-absorbing mat for throwing.
[0006]
In the above configuration, the oil-absorbing mat is folded or rolled up and stored in a state of being bound by a water-soluble binding material such as a paper string or a tape of a water-soluble polymer, and in use as it is. Throw it at the destination. After the dropped oil-absorbing mat falls onto the target water surface, the water-soluble binding material dissolves in water, and the water-absorbing swelling tube absorbs water and expands linearly. The plate is restored to a flat shape and immediately starts absorbing oil.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the specific contents of the present invention will be described with reference to the embodiments of FIGS. 1 to 3. In the drawings, reference numeral 1 denotes an oil-absorbing mat, and reference numeral 3 denotes a water-swellable tube. The oil absorption mat 1 used here needs to be made of a material capable of absorbing oil. Generally, a non-woven fabric is used, and more specifically, a polypropylene fiber having a certain thickness is used. Light oils such as gasoline, kerosene, light oil, and heavy oil A are particularly preferred because they are easily adsorbed.
[0008]
As the oil absorption mat 1, for example, use of a product name "Tafnel PH-50", which is sold by Mitsui Chemicals, Inc., can be considered. In addition, Toray Fine Chemical Co., Ltd. releases the product name “Wosep”, Kyushu Filter Industry Co., Ltd. releases the product name “KFO” or US National Solvent, Inc. “MAXXJ-50” Use is conceivable.
[0009]
In this case, the thickness of the oil-adsorbing mat 1 needs to be large enough to absorb the lost oil on the surface of the water to some extent. It is necessary to have a thickness of 4 mm or more. However, if the thickness exceeds 8 mm, the overall thickness becomes too thick and hinders throwing, so the thickness needs to be within the range of 4 mm to 8 mm.
[0010]
Regarding the size of the oil adsorption mat 1, if the diameter is less than 450 mm, not only the oil adsorption is not sufficient, but also it is not suitable for throwing. On the other hand, if the diameter exceeds 900 mm, the diameter must be 450 mm or more and 900 mm or less because the throwing becomes difficult.
[0011]
Further, the oil adsorption mat 1 is provided with a number of gelling agent pockets 2 and each gelling agent pocket 2 is filled with an oil absorbing gelling agent (not shown). Specific examples of the oil-absorbing powder gelling agent used here include a polystyrene / polybutadiene block polymer having a polystyrene block phase at both ends of the polymer, wherein the composition ratio of styrene and butadiene is one: styrene: 20. (Weight) parts or less, butadiene: 80 (weight) parts or more, the other one has a composition ratio of styrene: 40 (weight) parts or more and butadiene: 60 (weight) parts or less, and both have a molecular weight of 5 × 10 5 A powder gelling agent consisting of four or more two components can be used.
[0012]
In addition, a polystyrene block phase is provided at both ends of the polymer, one of which is a polystyrene / polybutadiene block polymer in which the composition ratio of styrene and butadiene is 20-40 parts by weight of styrene and 60-butadiene. One component is a polystyrene / polyethylene / butylene block polymer having a composition of 25 to 35 parts by weight of styrene and 65 to 75 parts by weight of ethylene / butylene. Can be used.
[0013]
As the use of the above-mentioned oil-absorbing powder gelling agent, for example, use of a product name “Alpha Gel Mat”, which is sold by Alpha Japan Co., Ltd., is preferable. Although not particularly shown, the oil-adsorbing mat 1 may be a laminated body in which an oil-absorbing powder gelling agent mat is interposed between two lipophilic fibers such as a nonwoven fabric.
[0014]
Further, the water-absorbing and expanding tube 3 attached along the outer peripheral edge of the oil-adsorbing mat 1 is made of a material capable of absorbing the water and expanding to restore the folded or rolled oil-adsorbing mat 1 to a flat shape. The content of the polymer is not particularly limited as long as the polymer is filled with a water-soluble polymer powder in a water-permeable tube such as a nonwoven fabric having a diameter of about 5 to 10 mm. When water is absorbed, it expands about 30 to 50 times, and the folded or rolled oil absorption mat 1 can be restored to a flat state.
[0015]
Further, as a water-soluble binding material for binding the folded or rolled oil absorption mat 1, for example, a paper string, a paper tape, a PVA (polyvinyl alcohol) -based film such as a water-soluble poval, or a natural high The use of water-soluble films of molecular type, semi-synthetic polymer type, synthetic polymer type, and the like can be considered.
[0016]
According to the present invention, in the above-described configuration, the oil absorption mat 1 is folded or rolled into two or four folds, and bound in that state with a water-soluble binding material (not shown) such as a paper cord or a water-soluble polymer tape. Also, keep it in a tied state, and throw it toward a target location on the water surface as it is when used. The spherical or massive oil-absorbing mat 1 that has fallen on the water surface dissolves the water-soluble binding material in water to release the binding, and the water-absorbing expandable tube 3 absorbs water to expand linearly (see FIG. 3). Accordingly, the oil adsorption mat 1 is quickly restored and spread in a flat plate shape on the water surface. The oil-adsorbing mat 1 restored and spread in a flat shape on the water surface starts to adsorb the oil, and the adsorbed oil is absorbed by the oil-adsorbing mat 1 and the gelling agent in the plurality of gelling agent pockets 2.
[0017]
【The invention's effect】
As described above, the present invention provides a polymer tube-type throwing oil obtained by folding an oil-absorbing mat having a water-absorbing swelling tube attached along the outer peripheral edge, or binding the oil-absorbing mat with a water-soluble binding material while being rounded into a spherical shape. Because it is a suction mat, the mat can be rolled into an unspecified shape and bound with a water-soluble binding material and thrown, and can be thrown farther than conventional products. Appropriate control becomes possible.
[0018]
In addition, since the binding material that binds the oil absorption mat is water-soluble, the binding is released immediately after landing, and the water-swelling tube attached along the outer edge of the oil absorption mat absorbs water and expands. As a result, the oil adsorption mat quickly restores to a flat state, and the oil adsorption can be started.
[0019]
Furthermore, since the oil-adsorbing mat is made into a laminated body by interposing an oil-absorbing powder gelling agent mat between two polymerized lipophilic fibers, the buoyancy of the gelling agent causes the oil-absorbing mat to be thrown on the water surface for a long time. The excess oil adsorbed by the lipophilic fiber is gelled by the oil-absorbing powder gelling agent of the oil-absorbing powder gelling mat, thereby preventing the oil from re-flowing.
