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十分な飛距離を確保でき、しかも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、これにより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、油の吸着能力を高め、しかも水面上において長時間にわたり沈降することがなく、また適度の保形成を維持させることにより投擲方向や距離の適確なコントロールを可能にした投擲用油回収材を開発したものであって、具体的には、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るとともに、その外周端縁に沿って比較的硬い材質からなる保形枠体を取り付けてなることを特徴とする投擲用油回収材に関する。
【0008】
本発明は上記の構成において、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たことにより、親油性繊維による油の吸着が十分でない場合においても内部の吸油性粉末ゲル化剤マットが油を吸着して上記した親油性繊維による油の吸着を補助的に促進させることができる。 また上記の三層構造とすることにより、全体として十分な質量が得られ、しかもその平盤状の形状を十分に保形することができるために、目的水面上に投擲する際にも投擲方向や距離のコントロールが容易になる。
【0009】
重合させた二枚の親油性繊維の外周縁端部を内折りして袋縫いにしてある場合においては、投擲する際における空気抵抗を減少させることができ、より一層遠方への投擲が可能となる。 また外周端縁に沿って比較的硬い材質からなる保形枠体を取り付けてなるために、油回収材としての平盤状の形状を、より一層十分に保形することができ、その結果投擲方向や距離のコントロールがより一層容易になる。
【0010】
【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示の実施例をもとに説明すると、各図において1は親油性繊維、3は吸油性粉末ゲル化剤マット、5は保形枠体をあらわしている。図1および図2にあらわした本発明の第1実施例においては、二枚の親油性繊維1・1の間に吸油性粉末ゲル化剤マット3を介在させるとともに、その外周端縁に沿って、例えばプラスチックなどの比較的硬い材質(より好ましくはある程度の質量を有するもの)からなる円形の保形枠体5を無端状に取り付けてなるものであり、さらにこれを後記する袋縫い部2の内側に装入させた状態にて相互に一体的に重合させている。
【0011】
なお図において2は袋縫い部をあらわし、投擲する際に空気抵抗を減少させる目的で重合させた二枚の親油性繊維1・1の外周縁端部を内側に内折りしてミシンにより袋縫いにしてある。 なお、ここで使用される親油性繊維1として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。
【0012】
親油性繊維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。
【0013】
またこの場合の親油性繊維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1mm以下では油吸着が十分ではなく、少なくとも2mm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2mm〜8mmの範囲内である必要がある。
【0014】
また親油性繊維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。
【0015】
さらに、二枚の親油性繊維の間に介在される吸油性粉末ゲル化剤マット3については、表面の親油性繊維1から滲み出す軽質油を含む鉱物油を吸着してゲル化し、再流出を阻止することができるものであれば格別材質や形状等は問わないが、一例を挙げれば図2にあらわしたように、一枚のシートに一定間隔毎に形成された多数の多孔質ゲル化剤ポケット4内に吸油性粉末ゲル化剤を収容してあるものが、油回収材の略全面にわたって吸油性粉末ゲル化剤が均等に配置されるので、より一層好ましい。
【0016】
また、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。
【0017】
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。
【0018】
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。
【0020】
さらに図3には、本発明の第2実施例が示されている。 この場合には上記第1実施例において用いた保形枠体5を、袋縫い部2の内側ではなしに外側に取り付けたものであって、この場合の取付手段としては親油性繊維1・1の外周端縁部に接着剤により接着し、あるいは周方向一定間隔毎に親油性繊維1・1の外周端縁部に針金により止着するなど、取付方法の手段を問わない。
【0021】
【発明の効果】
本発明は上記した通り、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たために、吸油性粉末ゲル化剤マットの浮力により、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。
【0022】
さらに二枚の親油性繊維と、その間に介在させた吸油性粉末ゲル化剤マットの3層構造により適度の保形成を維持することができ、その結果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。 また油回収材を回収した後においても油を吸着した二枚の親油性繊維から過剰な油が滴下(油垂れ)することがなく、衛生的であり、取り扱い性並びに作業性に優れる。
【0023】
また重合させた二枚の親油性繊維の外周縁端部を内折りして袋縫いにしてあるために、投擲に際して空気抵抗が少なく、その結果投擲飛距離が格段に向上する。 さらに外周端縁に沿って比較的硬い材質からなる保形枠体を取り付けてなるものであるために、油回収材の保形性がより一層十分となり、その結果投擲飛距離が少なくとも20m以上にも達することが可能となり、また多少の風があっても目的箇所へ性格に投擲することができるために、操作性が格段に向上する。

BACKGROUND OF THE INVENTION
The present invention relates to an oil recovery material for recovering, for example, heavy oil or other oil that has flowed into rivers, lakes, or oceans, and is capable of improving the oil absorption capacity and ensuring a sufficient flight distance and enabling linear flight. The purpose is to enable accurate anchoring to the target location from the riverbed, lake shore, or on the ship, thereby improving oil recovery efficiency and work safety.
[0002]
[Prior art]
An oil adsorbent that has been generally used for throwing has been known to have an oil adsorbing mat with a thickness of about 4 to 5 mm using a non-woven fabric, etc., and a weight of about 100 g. It has been.
[0003]
[Problems to be solved by the invention]
However, the above-mentioned general-purpose products do not have sufficient oil adsorption capacity, and also gradually adsorb water on the water surface and often settle in the water over time. There was a problem. Not only that, but because it is relatively flexible and inferior in shape, the shape becomes unstable during throwing, it is difficult to control the throwing direction and distance, and therefore it is very difficult to qualify throwing at the target location.
[0004]
[Means for Solving the Problems]
Therefore, the present invention is for anchoring that increases the ability to adsorb oil, does not settle for a long time on the surface of the water, and allows appropriate control of the anchoring direction and distance by maintaining appropriate retention. It is those which developed oil recovery member, specifically, Rutotomoni the oil absorbing powder gelling agent mat is interposed between two sheets of lipophilic fibers obtained by polymerizing relatively along its peripheral edge The present invention relates to an oil collecting material for anchoring, which is provided with a shape retaining frame made of a hard material .
[0008]
According to the present invention, in the above configuration, an oil absorbing powder gelling agent mat is interposed between two polymerized lipophilic fibers, so that the internal oil absorption even when the oil is not sufficiently adsorbed by the lipophilic fibers. The powdery gelling agent mat can adsorb oil and assist the adsorption of oil by the above-described lipophilic fiber. In addition, by adopting the above three-layer structure, a sufficient mass can be obtained as a whole, and the flat plate shape can be sufficiently retained, so that the throwing direction can be obtained even when throwing on the target water surface. And distance control becomes easier.
[0009]
In the case where the outer peripheral edge of the two polymerized lipophilic fibers is folded inward and sewed into a bag, the air resistance during throwing can be reduced, and throwing to a farther distance is possible. . In order to become attached shape retaining frame body made of a relatively hard material along the outer edge, the platen-like shape of the oil recovery member can be shape retaining even more fully, resulting throwing The direction and distance can be controlled more easily.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
In the following, the specific contents of the present invention will be described based on the illustrated embodiments. In each figure, 1 represents a lipophilic fiber, 3 represents an oil-absorbing powder gelling agent mat, and 5 represents a shape retaining frame. Yes. In the first embodiment of the present invention represented in FIGS. 1 and 2, along the two lipophilic fibers 1, 1 Rutotomoni the oil absorbing powder gelling agent mat 3 interposed therebetween, the peripheral edge For example, a circular shape retaining frame 5 made of a relatively hard material (more preferably having a certain mass) such as plastic is attached endlessly. They are polymerized integrally with each other in a state of being charged inside .
[0011]
In the figure, reference numeral 2 denotes a bag sewing portion, and the outer peripheral edge ends of the two lipophilic fibers 1 and 1 polymerized for the purpose of reducing the air resistance when throwing are folded inward to sew the bag with a sewing machine. is there. In addition, as the lipophilic fiber 1 used here, it is necessary to be of a material capable of absorbing oil, generally a nonwoven fabric is used, and more specifically, a polypropylene fiber having a certain thickness. However, it is preferable because light oils such as gasoline, kerosene, light oil, and heavy oil A are particularly easily adsorbed.
[0012]
As the lipophilic fiber 1, for example, use of the trade name “Toughnel PH-50” marketed by Mitsui Chemicals, Inc. can be considered. In addition, the product name “Wosep” released by Toray Fine Chemical Co., Ltd., the product name “KFO” released by Kyushu Filter Industrial Co., Ltd., or “MAXJJ-50” of National Solvent Corporation of the United States, etc. Use is conceivable.
[0013]
In addition, the thickness of the lipophilic fiber 1 in this case needs to have a thickness that can adsorb the run-off oil to some extent on the water surface. For this reason, if the thickness is 1 mm or less, the oil adsorption is not sufficient, and at least It is necessary to have a thickness of 2 mm or more. However, if the thickness exceeds 8 mm, the entire thickness becomes too thick and obstructs the throwing, so it is necessary to be within the range of 2 mm to 8 mm.
[0014]
Further, regarding the size of the lipophilic fiber 1, when the diameter is less than 450 mm, not only the oil adsorption is not sufficient, but also the unsuitable for anchoring. On the other hand, if it exceeds 900 mm, it is necessary that the diameter is not less than 450 mm and not more than 900 mm because it is difficult to throw.
[0015]
Furthermore, for the oil-absorbing powder gelling agent mat 3 interposed between the two lipophilic fibers, the mineral oil containing light oil that oozes out from the lipophilic fibers 1 on the surface is adsorbed and gelled, and then re-flowed. Any material or shape can be used as long as it can be blocked. As an example, as shown in FIG. 2, a number of porous gelling agents formed on a sheet at regular intervals. What contains the oil-absorbing powder gelling agent in the pocket 4 is even more preferable because the oil-absorbing powder gelling agent is evenly arranged over substantially the entire surface of the oil recovery material.
[0016]
In addition, 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, and one component ratio of styrene and butadiene is styrene. : 20 (weight) or less, butadiene: 80 (weight) or more, and the other one has a composition ratio of styrene: 40 (weight) or more and butadiene: 60 (weight) or less, and the molecular weight is 5 A powder gelling agent composed of 2 components of × 10 4 or more can be used.
[0017]
In addition to this, a polystyrene block phase is provided at both ends of the polymer, and one is a polystyrene / polybutadiene block polymer having a styrene / butadiene ratio of 20-40 (weight), butadiene: 60- 80 parts by weight, the other is a two-component polystyrene / polyethylene / butylene block polymer with a structure of styrene: 25-35 (weight), ethylene / butylene: 65-75 (weight). The powder gelling agent consisting of can be used.
[0018]
As the use of the above oil-absorbing powder gelling agent, for example, the use of the trade name “alpha gel mat” which is related to the sale of Alpha Japan Co., Ltd. is preferable.
[0020]
Further in FIG. 3, there is shown a second embodiment of the present invention. In this case, the shape-retaining frame body 5 used in the first embodiment is attached to the outside rather than the inside of the bag stitch portion 2, and the attachment means in this case is the lipophilic fiber 1.1. Any attachment method may be used, such as bonding to the outer peripheral edge with an adhesive, or fixing to the outer peripheral edge of the lipophilic fiber 1 or 1 with a wire at regular intervals in the circumferential direction.
[0021]
【The invention's effect】
In the present invention, as described above, the oil-absorbing powder gelling agent mat is interposed between the two polymerized lipophilic fibers. The excess oil adsorbed by the lipophilic fibers does not settle over time, and is gelled by the oil-absorbing powder gelling agent of the oil-absorbing powder gelling agent mat, thereby preventing reflow of the oil.
[0022]
Furthermore, two layers of lipophilic fibers and an oil-absorbing powder gelling agent mat interposed between them can maintain an appropriate retention, resulting in precise control of the throwing direction and throwing distance. It becomes possible. In addition, even after the oil recovery material is recovered, excess oil does not drip (oil dripping) from the two lipophilic fibers adsorbed with oil, which is hygienic and excellent in handling and workability.
[0023]
Further, since the outer peripheral edge portions of the two polymerized lipophilic fibers are folded inward and sewed into a bag, air resistance is low at the time of throwing, and as a result, the throwing distance is greatly improved. Furthermore, since the shape retaining frame made of a relatively hard material is attached along the outer peripheral edge, the shape retention of the oil recovery material is further improved, and as a result, the throwing distance is at least 20 m or more. In addition, even if there is some wind, it is possible to throw the character into the target place, so the operability is greatly improved.
