The present invention provides a novel oil-absorbing material made of a synthetic resin that has excellent oil-absorbing performance. In recent years, there has been a great social need to remove oil and fat from water in order to prevent environmental pollution and effectively utilize water resources, and the emergence of high-performance oil-absorbing materials is desired. As synthetic resin oil absorbing materials, those made of polypropylene and polyurethane are known, but these are better called oil absorbing materials rather than oil absorbing materials, and the oil absorption of the material itself is better. The capacity is poor, and most of the oil is adsorbed on the surface, so the amount of oil absorption is small. In addition, it is necessary to increase the surface area of these materials by means such as fiberization or foaming.
This poses a problem in terms of productivity and cost. In addition, because of their special shape, their usage is limited, and their handling requires some ingenuity. Materials that absorb oil well include unvulcanized natural rubber and synthetic rubber (hereinafter abbreviated as rubber).
Rubber treated with oil to a high degree swells or aggregates to a large extent, and its physical properties deteriorate significantly, making it impossible to use it as an oil absorbing material. Furthermore, since all of these oil absorbing materials are hydrophobic materials, they have poor water leakage properties. Therefore, it was difficult to set it in water, and the absorption rate of the oil dispersed in water was not very fast. Furthermore, oil-absorbing materials made by mixing rubber with hydrophobic lipophilic polymers are also known, but although they have oil-absorbing ability, they do not improve the above-mentioned drawbacks of rubber, and they also have a poor oil-absorbing ability. It was undesirable as an oil absorbing material because of the hydrophobic nature of the oil absorbing material itself. On the other hand, as an inorganic oil absorbing material,
38770 and JP-A-51-120050, there are known water treatment materials comprising an inorganic substance having a specific function and an organic polymer compound as a carrier thereof. JP-A-51-38770 describes a fine composite (Example 1) consisting of inorganic fine particles, such as magnesium oxide, and an organic polymer, such as high-density polyethylene, that potentially has emulsified oil treatment properties. Furthermore, Japanese Patent Application Laid-open No. 120050/1987 describes a substance that is physicochemically active against substances contained in water to be treated, such as magnesium oxide, and a carrier thereof, such as kaolin clay (examples). 1), a water treatment material composed of polystyrene granules (Example 3) is described. These oil-absorbing materials are characterized by the use of an inorganic substance that has oil-absorbing properties as one of their components. However, these inorganic substances do not necessarily have excellent oil absorption ability and cannot sufficiently meet recent social needs. From the above viewpoint, the present inventors have developed an oil-absorbing material whose main component is rubber, which does not impair the excellent oil-absorbing properties of rubber and which does not cause the rubber to swell or coagulate when it absorbs oil, making it unusable. As a result of intensive studies to obtain the above-mentioned results, we found that a mixed polymer obtained by mixing an acrylonitrile-based (co)polymer with rubber can overcome the above-mentioned drawbacks of rubber and fully achieve the purpose of the present invention.
Discovered that it is very good as an oil absorbing material,
After further research and improvement, the present invention was completed. That is, the gist of the present invention is an oil absorbent material comprising a mixture of 10 to 70% by weight of an acrylonitrile-based (co)polymer and 90 to 30% by weight of a thermoplastic elastomer consisting of a conjugated diolefin and a monovinyl-substituted aromatic compound. That is. The acrylonitrile polymer, which is a component of the oil absorbent material of the present invention, is a hydrophilic polymer that has the highest wet tension against water among synthetic resins, and is also a material with extremely excellent solvent resistance. Since this polymer has no oil absorption ability, it was previously unthinkable to use this polymer alone as an oil absorbing material, let alone as a component of an oil absorbing material. In the present invention, an acrylonitrile-based (co)polymer, which is hydrophilic and has no oil absorption ability and has never been used as an oil absorbing material, is mixed with a thermoplastic elastomer to make an oil absorbing material. Therefore, the above-mentioned drawbacks of thermoplastic elastomers when absorbing oil are solved. Furthermore,
Surprisingly, by mixing an acrylonitrile-based (co)polymer, the oil absorption rate is faster than in the case of a thermoplastic elastomer alone, and the amount of oil absorption hardly decreases. Furthermore, since the hydrophilicity of the oil-absorbing material is improved, oil dispersed in water can be absorbed sufficiently quickly. The configuration, embodiments, and effects of the present invention will be described in detail below. The oil absorbent of the present invention is an acrylonitrile-based (co-)
It is necessary that it is a mixture of a thermoplastic elastomer consisting of a polymer, a conjugated diolefin, and a monovinyl-substituted aromatic compound. Acrylonitrile-based (co)polymers have the highest wet tension against water among synthetic resins,
It is also known for its high affinity for water, good water leakage, and high solvent resistance. Conversely, thermoplastic elastomers made of conjugated diolefins and monovinyl-substituted aromatic compounds are known for their lipophilic properties and high oil absorption properties. By mixing these two, the high solvent resistance of the acrylonitrile (co)polymer allows it to absorb oil even at a high level without impairing the high oil absorption performance of the thermoplastic elastomer. It prevents the material from swelling and prevents the oil-absorbing material from settling or adhesion, giving it a dramatically longer service life and also being easier to handle. Furthermore, the hydrophilicity of the acrylonitrile-based (co)polymer allows the oil absorbent to have good water leakage properties, so that the absorption rate of the dispersed oil in water is extremely high. In addition, by using the oil absorbent material of the present invention, it not only removes oil and fat from water, but also has the ability to aggregate and coarsen suspended solids in water (hereinafter abbreviated as SS) on the surface of the oil absorbent material. Most of it can be separated and removed. In the oil absorbent material of the present invention, it is desirable that the content of the acrylonitrile polymer is in the range of 10 to 70% by weight. The acrylonitrile content of the acrylonitrile (co)polymer is preferably 30% by weight or more, more preferably 50% by weight or more. As mentioned earlier, the oil absorbent material of the present invention has a balance between the high hydrophilicity and solvent resistance of the acrylonitrile-based (co)polymer and the lipophilicity of the thermoplastic elastomer.
Large oil absorption amount and oil absorption rate, high SS removal rate,
When absorbing oil, it prevents the oil-absorbing material from settling and agglomerating, resulting in an oil-absorbing material with a long lifespan.Those that lack any of these properties outside the above range. This is undesirable. The acrylonitrile-based (co)polymer used in the present invention is one having an acrylonitrile content of 30% by weight or more, and refers to an acrylonitrile homopolymer, an acrylonitrile copolymer, and an acrylonitrile graft copolymer.

Using a fluidized bed tester, a perforated tube connected to a pump is installed in the lower chamber, an air vent is installed at the top, and a circulation pump is connected via piping so that the processing liquid flows from top to bottom. After filling the oil absorbing material filling chamber with an apparent volume of 5 and weight of approximately 3 kg, 100 ml of oil-containing wastewater was poured into the chamber, and while being circulated from top to bottom at a flow rate of 20 min. The oil absorbent material is made to flow uniformly by blowing air at 20 to 40 minutes per minute through the connected porous pipes. After continuing the fluidized state for 10 minutes, the treated water was extracted and analyzed for oil and SS.
