Description

Oil-Absorbing Fabric which adsorbs oil components [0003]

One aspect of the present invention relates to an adsorbent for adsorbing an oil component, and more particularly, to an oil absorber for absorbing oil discharged from an ocean or the like, and waste oil during vehicle maintenance.

The contents described in this section merely provide background information on the embodiment of the present invention and do not constitute the prior art.

Recently, large and small oil spills are frequently generated from many ships operating in the coastal waters. These leaked oil not only pollutes the coastal waters, but also pours into the coastline and seashore along the tidal currents, Water pollution is becoming more serious by the various oil components flowing out from the surrounding city, the factory, the water pipe, the oil tanker, etc. in the inland lakes and the like.

Examples of the method of removing the oil leaking to the inner surface of the outer surface including the coastal area include a method of spraying the oil with neutralizing oil, a method of collecting the oil after adsorbing the oil with the oil absorbing filter, A method of installing an oil prevention film so that the oil does not spread on the water surface, and the like are used.

Among the above methods, the method of spraying the emulsifier may be to remove the oil by neutralizing it, but there is a possibility that secondary chemical contamination is caused by the chemical component of the emulsifier, and the method of installing the oil- There is a disadvantage in that it is not possible to substantially remove the oil floating on the water surface although the diffusion of the floating oil component can be partially blocked.

Therefore, the most widely applied method for removing oil leaking to the inner and outer water surfaces is to use an oil absorbing material. Typical examples of such oil absorbing material include a porous fabric or a nonwoven fabric formed into a bag shape, And an oil-absorbing cloth made by weaving a porous material such as an oil-absorbing cloth made by filling a hair or bird's feathers or the like with a specific shape.

Due to the deterioration of the oil adsorption performance, there is a problem that a large amount of oil absorption tank and a lot of operation time are required in the operation of removing oil from the inside and the outside water.

Particularly, a product made by weaving an oil-absorbing foam or a strawberry using feathers of algae has a somewhat large volume, which makes it difficult for workers to easily use it, and since the material itself absorbs a large amount of water together with oil, The removal efficiency of the oil through the oil absorbing film is further reduced in proportion to the water absorption amount and the weight of the oil absorbing film is heavy after the oil removing operation is performed so that handling and transportation of the oil absorbing film is also very difficult.

On the other hand, in order to prevent the oil from dropping on the floor when the vehicle is being repaired at a railroad car maintenance shop, a newspaper is laid out or a general outdoor mat is laid. When using a newspaper, a newspaper is blown In addition, it is troublesome, and a blown newspaper can touch a fire (gas range, etc.), and there is a possibility of fire. In case of using outdoor mats made of general foamed resin, troublesome cleaning work is required to remove oil have.

In addition, such a problem is that when an individual car is being repaired or when repairing various kinds of machinery such as a gun, an engine saw, and a lawn mowing machine, etc., the various oils or fuels buried in the operating portion of the machine do not contaminate the floor In this case, it is necessary to use a new one every time, and paper box or cloth contaminated with oil or the like is difficult to be reused.

FIG. 1 shows a structure of an oil absorption filter for preventing oil leakage according to an embodiment of the present invention.

The oil absorption cap 10 for preventing leakage of oil according to an embodiment of the present invention may be provided to adsorb oil to prevent marine or lake pollution by oil when an oil leakage accident occurs in the ocean or a lake, May be provided to adsorb the oil to prevent soil contamination by the oil.

The structure of the oil absorption cap 10 for preventing oil spill according to the present embodiment includes an oil absorption layer 100 formed by a melt blown process and having a structure including a plurality of voids and absorbing oil;

And has a structure that is formed by a spun bond method and is denser than the oil absorbing layer 100. When the oil absorbing layer 100 adsorbs oil, the oil absorbing layer 100 is fixed so that the structure is not loosened A base layer 200; And

And a film layer 300 coated on the base layer 200 to prevent oil adsorbed on the oil-absorbing layer 100 from leaking out to the outside.

The oil absorbing layer 100 mainly functions to adsorb oil. To perform this function, the interior of the oil absorbent layer 100 has a plurality of voids, which provide an oil adsorption space. The oil-absorbing layer 100 has a density lower than that of the base layer 200, and is bulky, i.e., bulky.

The oil absorbing layer 100 may be formed by molding a synthetic resin such as polyethylene (PE), polypropylene (PP), or nylon with a meltblown method to form a structure having a plurality of voids. Particularly, in the case of using a propylene-based polymer, it is easier to obtain fine fibers because of good radioactivity as compared with the case of using an ethylene polymer, and excellent performance such as strength, flexibility, uniformity and light- The absorbent layer 100 may be formed of a polypropylene fiber web.

The base layer 200 mainly performs the function of maintaining the shape of the oil absorbing layer 100, that is, the function of providing the oil absorbing layer 100 with the morphological stability, and the function of adsorbing the oil can also be performed incidentally. Since the oil absorbing layer 100 forms a bulky shape having a plurality of voids, there is a problem that when the oil is absorbed, the structure is disintegrated and collapsed. Particularly, when the oil absorbing cloth mounted on the sea is scratched with hooks in the marine pollution control work, the oil absorbing layer 100 is torn and torn due to moisture, so it is difficult to raise. The base layer 200 fixes the oil absorbing layer 100 and maintains the shape of the oil absorbing layer 100, so that the problem can be solved.

The base layer 200 may be formed of the same material as that of the oil absorbing layer 100 to have the same thickness as the oil absorbing layer 100 in order to perform the function of maintaining the shape of the oil absorbing layer 100 It may be formed to be thin and high in density.

The thickness ratio of the base layer 200 and the oil-absorbing layer 100 of the same material is preferably 1: 3 to 10. If the ratio is less than 1: 3, the absorption function of the oil absorbing layer 100 may be deteriorated. If the ratio is larger than 1:10, the function of the base layer to maintain the shape of the oil absorbing layer 100 may deteriorate.

The base layer 200 may be formed by molding a synthetic resin such as polyethylene (PE), polypropylene (PP), nylon or the like by a spunbond method, depending on the embodiment. However, for the same reason as that of the oil absorbing layer 100, It is preferably formed by molding with a spun bond method.

The oil absorption nozzle 10 for preventing oil leakage according to the present invention may have a different laminated structure according to the embodiment. That is, the first embodiment of the oil absorption cap 10 for preventing oil leakage according to the present invention may have a structure in which the oil absorption layer 100, the base layer 200, and the film layer 300 are stacked in order, The example may have a structure in which the oil absorbing layer 100, the film layer 300, and the base layer 200 are stacked in order. Fig. 1 shows a case of the first embodiment of the oil absorption cap 10 for preventing oil spillage.

Hereinafter, referring to Figs. 2 to 4, a first embodiment of the oil absorption cap 10 for preventing oil spill according to the present invention will be described.

FIG. 2 shows a state in which the oil absorbing layer and the base layer are bonded to each other according to a first embodiment of the present invention. Fig. 2 (a) is a plan view showing a plurality of point-adhering regions forming an array at regular intervals, and Fig. 2 (b) is a side view.

The oil absorbing layer 100 and the base layer 200 are laminated in order, and they can be laminated by ultrasonic bonding or the like. In order to allow the oil absorbing layer 100 to absorb more oil, the oil absorbing layer 100 and the base layer 200 may have a structure in which only a part thereof is adhered and the other part is not adhered have. That is, it may have a structure in which an adhesive region and a non-adhesive region are formed between the oil absorbing layer 100 and the base layer 200.

This structure can maximize the bulky property of the oil absorbing layer 100 while the oil absorbing layer 100 is bonded to the base layer 200. In order to realize such a structure, the bonding process may be performed so that the adhesion region where the oil absorbing layer 100 and the base layer 200 are adhered to each other has a certain pattern upon ultrasonic bonding. The pattern of the adhesive region may include, for example, a plurality of point bonding (A, see Fig. 2) forming an array at regular intervals or a plurality of pre-bonding forming an array at regular intervals.

The heat fusion by the ultrasonic bonding hardens the structure of the bonded portion, thereby eliminating the glue property of the oil absorbing layer 100 and deteriorating the oil absorption function. The absorbing function of the oil absorbing layer 100 can be maximized by maximizing the portion having the bulky property of the oil absorbing layer 100 by adopting a structure in which the oil absorbing layer 100 and the base layer 200 are partially bonded.

According to an embodiment of the present invention, the oil-absorbing member 10 according to the present invention may have a structure in which a plurality of oil-absorbing layers 100 having different pore sizes formed therein are stacked. The oil absorbing layer 10 may have a structure in which the oil absorbing layer 100 having a larger pore size is located on the inner side (the inner side means a side bonded to the base layer 200) have.

This structure makes it possible to increase the size of the adsorption space from the oil absorbing layer 100 located on the outer side of the oil absorbing container 10 to the oil absorbing layer 100 located on the inner side of the oil absorbing container 10, And the arrangement of the voids necessary for adsorption of the oil component can be optimized by the structure in which the plurality of oil absorbing layers 100 are laminated.

According to the arrangement of the above-described gaps, when the oil removing operation is performed using the oil absorption nozzle 10 according to the present invention, the oil absorption nozzle 10, which is located outside the oil absorption nozzle 10, The oil component can be adsorbed and guided to the oil absorbing layer 100 positioned on the inner side of the inner oil absorbing layer 100 more quickly than the inner oil absorbing layer 100. On the other hand, , The oil component induced to the inside of the oil adsorption film 10 can not easily flow out to the outside.

FIG. 3 illustrates a process of absorbing oil in the oil absorbent during the marine pollution control in the first embodiment of the oil absorbent 10 for preventing oil leakage according to the present invention. Fig. 3 (a) shows an oil-absorbing film having a structure without a film layer, and Fig. 3 (b) shows a oil-absorbing film having a structure having a film layer.

The film layer 300 of the oil-absorbing membrane 10 according to the present invention functions to prevent oil from leaking out when the oil absorbing layer 100 absorbs oil. The film layer 300 may be formed of a waterproof material such as polyethylene (PE), vinyl, or the like.

The first embodiment of the oil-absorbing film 10 according to the present invention may have a structure in which the film layer 300 is coated on the base layer 200. The film layer 300 may have a structure in which the surfaces of the base layer 200 and the base layer 200 are fused to each other in order to perform an oil leakage prevention function. .

3, the operation of the oil suction nozzle 10 according to the first embodiment of the present invention will be described in the marine pollution control work. In the case where the oil absorbing film 10 is placed in the sea to perform an oil control operation in the event of an oil spill incident in the ocean, the oil absorbing film 10 is formed so that the oil absorbing layer 100 comes into contact with the surface of the sea, The base layer 200 is located on the upper surface and the film layer 300 is located on the upper surface of the base layer 200.

In this structure, the oil-absorbing layer 100 functions to absorb oil from the sea, and the base layer 200 has a function of fixing the oil-absorbing layer 100 so that the oil-absorbing layer 100 absorbing oil keeps its shape .

3 (a), in the structure having no film layer structure, the oil B absorbed in the upward direction P from the oil absorbing layer leaks from the upper surface of the base layer, and the leaking oil B is absorbed in the wave It can be a result of sweeping back into the sea and discharging the absorbed oil. This lowers the oil absorption rate of the oil adsorbent.

3 (b), the oil absorption nozzle 10 according to the present invention employs a structure in which the film layer 300 is formed on the upper surface of the base layer 200, To prevent the oil absorbed from the upper surface of the base layer 200 from leaking out to improve the oil absorption rate of the oil absorption nozzle 10.

On the other hand, in order to prevent pollution of the bottom due to waste oil such as engine oil during the maintenance of railway, vehicle, etc., the oil absorption nozzle 10 can be laid on the bottom surface of the maintenance shop.

That is, when maintenance of a vehicle such as a train, the oil absorber 10 is laid under the vehicle and the vehicle is maintained. When the oil is dropped, the layer formed by the spunbond method and the meltblown method is not waterproofed and the oil leaks to the floor There is a problem of polluting the floor.

The oil sorbent 10 according to the present invention can solve this problem by adding the film layer 300 configuration.

The base layer 200 is positioned on the upper surface of the film layer 300 and the base layer 200 is disposed on the lower surface of the base layer 200. In this case, The structure in which the oil absorbing layer 100 is disposed on the upper surface of the base material layer 200 does not include the film layer 300. In the structure without the film layer 300, The bottom of the workshop is unsanitary and the water absorption of the oil absorbing layer 100 is lowered. However, since the structure in which the film layer 300 is formed blocks the oil leaking through the base layer 200, the bottom is hygienic, 100) to collect more oil.

FIG. 4 shows a state in which a vapor discharging structure is formed in the oil absorbing container according to the first embodiment of the present invention. Fig. 4 (a) shows an oil absorbing film having a film layer having a ventilation structure, and Fig. 4 (b) shows a oil absorbing film having a film layer having no venting structure.

The oil sorbent 10 according to the present invention may have the ventilation structure 310 of the film layer 300. This vent structure 310 performs the function of discharging the vapor 400.

The base layer 200 has a density higher than that of the oil absorbing layer 100 but is permeable enough to allow the oil vapor 400 to smoothly pass therethrough and the film layer 300 coated on the base layer 200 May also have vent structure 310. Here, the ventilation structure 310 may mean a structure having a plurality of pores. The plurality of pores formed in the film layer 300 can not pass water, but the vapor 400 passes. The film layer 300 can discharge the oil vapor 400 generated from the oil collected in the oil absorbing layer 100 through the pores.

4 (a) shows a state in which the vapor 400 is discharged through the ventilation structure of the film layer. The oil absorbing coating 10 according to the present invention has a structure in which the oil absorbing layer 100 and the air permeable film layer 300 are respectively attached to both sides of the base layer 200 so that the oil accumulated in the oil absorbing layer 100 It is possible to discharge the vapor 400 generated from the collected oil while blocking the leakage of the oil B from the base layer 200 to the outer surface of the film layer 300.

That is, during the marine pollution control work, the oil absorbing layer 100 contacting the seawater absorbs the oil. At this time, the pressure of the oil absorbing layer 100 on the side contacting the seawater is the highest and the pressure Is getting lower. Therefore, the oil vapors 400 generated from the oil B absorbed by the oil absorbing layer 100 move upward in the direction P, that is, toward the film layer 300 from the seawater and pass through the pores of the film layer 300 And is discharged into the atmosphere. Since the oil vapor 400 generated from the oil B is smoothly discharged, the oil absorption space can be secured in the oil absorption layer 100, and effective oil absorption can be achieved.

Fig. 4 (b) shows a state in which the discharge of the vapor 400 is blocked in the oil adsorption film 10 having the film layer 300 having no vent structure. In the absence of the ventilation structure 310, the vapors 400 generated in the oil absorption nozzle 10 can not be discharged and are trapped, so that the oil absorption space is eroded and the oil absorption effect of the oil absorption nozzle 10 is remarkably deteriorated .

On the other hand, if the oil suction nozzle shown in FIG. 4 is turned upside down, the structure of the oil suction nozzle 10 at the time of maintenance work becomes a structure (not shown).

In this case, in order to prevent contamination on the floor due to oil, the film layer 300 of the oil absorbing film 10 is attached to the bottom surface So that the oil suction nozzle 10 is overlapped.

The film layer 300 has a function of preventing leakage of oil to prevent contamination of the floor, but prevents the vapor 400 generated in the collected oil from being discharged to the outside.

Since the vapors are highly volatile, there is a risk of fire if the vapors (10) are faded with vapor, and there is a risk of human accidents. Therefore, it is necessary to discharge the vapors 400 generated from the collected oil in real time.

Since the film layer 300 has the ventilation structure 310, the oil sorbent 10 according to the present invention discharges the vapor 400 in real time, thereby reducing the risk of fire and preventing accidents.

5 shows a state in which a vapor discharging structure is formed in an oil absorbing container according to a second embodiment of the present invention. That is, a film layer 300 with a vent structure 310. [

A second embodiment of the oil absorption nozzle 10 for preventing oil leakage according to the present invention will be described in comparison with the first embodiment.

In order to solve the problem of difficulty in raising the oil absorbing layer 100 when the oil absorbing layer 100 is scraped off due to moisture when the oil absorbing layer 10 seated on the sea is raked up during the marine pollution control work, And the function of maintaining the shape of the oil absorbing layer 100 is performed. In this case, according to the structure of the first embodiment, since the oil absorbing layer 100, the base layer 200, and the film layer 300 are sequentially stacked from the sea surface, the film layer 300 is exposed to the uppermost layer, Since the base layer 200 is formed of a very thin and soft material, the base layer 200 is formed by a sponge-bonding method and is strong enough not to be released by moisture. However, when the base layer 200 is scraped with a hook, There is a problem that the oil accumulated in the oil absorbing layer 100 is broken due to the damage of the film layer 300 and the sea is re-contaminated.

However, according to the structure of the second embodiment, since the oil absorbing layer 100, the film layer 300, and the base layer 200 are sequentially stacked from the sea surface, a systematically strong base layer 200 is exposed to the uppermost layer And the soft film layer 300 is positioned under the base layer 200 and is protected by the base layer 200 so that damage to the film layer 300 can be prevented even if it is scratched with a hook. Accordingly, it is possible to prevent the oil collected in the oil absorbing layer 100 from being discharged again, thereby preventing re-contamination of the sea.

5, the oil absorbing layer 100 absorbs the oil B from the sea, but the absorbed oil B is sealed by the film layer 300 and does not leak to the outside, but only the oil vapor 400 Passes through the ventilation structure (310) and the base layer (200) and is diverted to the outside. In this case, since the film layer 300 is located between the base layer 200 and the oil-absorbing layer 100, the oil-absorbing layer is not damaged even if the operator scrapes the oil-absorbing film with the hooks.

FIG. 6 shows a method of manufacturing an oil-absorbing filter according to another embodiment of the present invention.

Another embodiment of the present invention is a method for manufacturing an oil absorption filter for preventing oil leakage, which is provided to adsorb oil in order to prevent pollution of marine, lake or soil by oil when an oil spill accident occurs in the ocean or lake, As a result,

A base layer manufacturing step (S100) of forming a base layer (200) by molding a polypropylene (PP) fiber by a spun bond method; An oil absorbing layer manufacturing step (S110) of forming a water absorbing layer (100) for absorbing oil by molding polypropylene (PP) fibers by a melt blown process;

A film coating step (S120) of coating a film layer (300) on one side of the base layer (200) to prevent the oil absorbed in the oil absorbing layer (100) from being discharged again; And

(S130) of assembling the oil absorbing layer (100) onto the base layer (200) coated with the film layer (300) after the film coating step (S120) Method can be provided.

According to the embodiment, the oil absorbing layer 100 may be formed so that the oil absorbing layer 100, the base layer 200, and the film layer 300 are stacked in order.

According to the embodiment, the oil absorbing layer 100 may be prepared so that the oil absorbing layer 100, the film layer 300, and the base layer 200 are stacked in order.

According to the embodiment, the oil absorbing layer forming step (S130) may be performed by releasing the base layer (200) and the oil absorbing layer (100) from the rolled base layer roller and the rolled oil absorbing layer roller, As shown in Fig.

After the oil absorbing layer deposition step (S130), the oil absorbing layer may be wrapped. The packaging step will be described later.

It may be subjected to a step of forming a vent structure in the film before the film coating step (S120). This may be performed by mixing calcium carbonate or the like in the course of producing the film and then forming pores in the film through a stretching process or the like.

The size of the pores formed in the vent structure of the film is such that the air passes but not the water particles.

The manufacturer may coat the base layer 200 with a film having a ventilation structure by thermal fusion or the like and then adhere the oil absorbing layer 100 to the base layer 200.

In this case, if the base layer 200 and the oil-absorbing layer 100 are adhered to each other, the surface of the oil-absorbing layer 100 is rough, so that the surface of the base layer 200 to be coated with the film layer 300 becomes coarse, It is difficult to coat the substrate 300. The film coating step S120 for coating the film layer 300 on the base layer 200 is performed first and then the oil absorbing layer forming step S130 for bonding the base layer 200 and the oil absorbing layer 100 is performed .

The base layer 200 and the film layer 300 are smooth and even as compared with the oil absorbing layer 100, although the oil absorbing layer 100 has a structure in which the structure is tangled. Although the base layer 200 is dense and rigid in structure, the film layer 300 is soft, soft, and prone to tearing.

Therefore, the process of attaching the film layer 300 to the base layer 200 is performed first, thereby imparting rigidity to the film layer 300, and at the same time, the entirety of the film layer 300 is smoothly coated on the base layer 200 , And then the oil absorbing layer 100 is formed on the improved strength film layer 300 or the base layer 200 to improve the hermeticity of the film.

Specifically, in the case of manufacturing the lubricant absorbent 10 having the structure of the first embodiment described above, after the laminating process of attaching the oil absorbing layer 100 and the base layer 200 is performed first, the base layer 200, The surface of the base layer 200 is not smoothly retained due to the difference in roughness between the oil absorbing layer 100 and the base layer 200, There arises a problem that the film layer 300 is not smoothly coated on the base layer 200. Accordingly, it is preferable to perform the coating process first to completely close the base layer 200 and the film layer 300, followed by the oil-absorbing layer forming process.

In the case of manufacturing the oil absorbing film having the structure of the second embodiment described above, the process of attaching the oil absorbing layer 100 and the film layer 300 is performed first, and then the base layer 200 is formed on the film layer 300 There is a problem that the film layer 300 is not smoothly coated on the entire surface due to the difference in roughness between the oil absorbing layer 100 and the film layer 300. [ Therefore, it is preferable to perform the coating process first, and the process of assembling the oil absorbing layer 100 to the film layer 300 after the base layer 200 and the film layer 300 are closely contacted.

The base layer 200 coated with the oil absorbing layer 100 and the film layer 300 may be provided in a roll form and may be rotatably installed at predetermined positions. Then, the oil-absorbing layer sheet and the base layer sheet released from the roll-shaped oil-absorbing layer 100 and the roll-shaped base layer 200 are bonded by ultrasonic bonding.

After the base layer 200 coated with the oil absorbing layer 100 and the film layer 300 is pressed and bonded by ultrasonic bonding, the base layer 200 may be packaged according to one or more of the following three methods.

That is, after cutting to a length of 40 Cm and a width of 60 Cm to 80 Cm through a cutting process according to an embodiment, a certain number of sheets may be stacked and packaged.
