  Since the present invention is configured as described above, unlike the conventional example described above, the water contained in the object to be treated can be absorbed in a small amount by the water-absorbing resin, so that it is not bulky when stored or carried, and the water absorption treatment Since it does not become bulky later, disposal processing can be performed easily, and furthermore, the surface of the water-absorbing resin absorbed by the carbon material is covered with the carbon material due to the carbon material floating in the water. (Urine), vomit, and food residue that emit odors, this charcoal suppresses the odor emitted from the object to be treated and conceals the object to be treated. Can be easily disposed of.

  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.

  For example, when the water-absorbing treatment material according to the present invention is sprinkled on the treatment object A, the water 1 contained in the treatment object A is absorbed by the water-absorbing resin 3, and the water 1 contained in the treatment object A is granular. Alternatively, the powdery carbon material 2 floats, and the surface of the water absorbent resin 3 that has absorbed the water 1 is covered with the carbon material 2.

  Therefore, the water 1 contained in the treatment object A is absorbed by the water absorbent resin 3 having better water absorption than the rice husk charcoal described above, so that the water 1 contained in the treatment object A is absorbed by a small amount of water. Since the resin 3 can absorb water, it is not bulky when stored or carried, and it is not bulky even after the water absorption treatment, so that the disposal process can be performed easily.

  Further, the surface of the water-absorbing resin 3 that has absorbed the water 1 contained in the processing object A will be covered with the carbonaceous material 2, and therefore, if the processing object A emits odor, this processing object The odor emitted from the object A is suppressed by the carbonaceous material 2, and the processing object A is concealed by the carbonaceous material 2, making it easy to dispose of it in terms of appearance.

  Specifically, when the processing object A is, for example, excrement (urine), when the water-absorbing treatment material according to the present invention is sprinkled on the urine A, the water 1 contained in the urine A is absorbed by the water-absorbing resin 3. The scent of the urine A is held in the water absorbent resin 3. Further, the surface of the water-absorbing resin 3 that has absorbed the water 1 contained in the urine A is in a state in which the carbon material 2 is floated and covered with the water 1 contained in the urine A, and thus the carbon material 2 serves as a lid. The odor of the urine A is suppressed from being scattered, and the odor absorption function of adsorbing the odor of the carbonaceous material 2 is also used to suppress the odor of the urine A from being scattered. The top is also easy to dispose of (reducing discomfort to the eyes).

  In addition to this, as the processing object A, for example, stool as excrement containing water 1 and ramen juice as food residue are also processing objects A, and the same effect is obtained when they are actually processed. Demonstrated.

  A specific embodiment of the present invention will be described with reference to the drawings.

  The present embodiment is for water-absorbing the object to be treated A, and has a water-absorbing resin 3 having water absorption, and a granular or powdery carbonaceous material 2 floating in water 1 or an odor adsorbing performance floating in water 1. The porous material which has.

  The processing object A includes, for example, water 1 (moisture) such as excrement (urine / stool), vomit, and food residue (for example, ramen juice) as well as drinking water, soft drinks, and alcoholic beverages. There is a wide range of processing objects A that can be treated with the water-absorbing treatment material according to the present embodiment.

  Hereinafter, each component according to the present embodiment will be described in detail.

  The water-absorbing resin 3 is in the form of powder as illustrated in FIG. 1 and gels by holding the water 1 absorbed. The water-absorbing resin 3 may be granular or may be a relatively large plate or block.

  Specifically, in this embodiment, the water-absorbing resin 3 is a highly water-absorbing resin having a high water-absorbing property and water-retaining property (for example, SunFresh ST-250 (registered trademark) ST900E / acrylic acid monomer-containing Sanyo Chemical Co., Ltd.). Resin / Acrylate (highly water-absorbing resin of acrylic acid polymer partial sodium salt)) is used, and its performance is about 700 times its own weight (700 g / g). . In addition, the specific gravity of the water absorbing resin 3 which concerns on a present Example is 0.63.

  Further, in this embodiment, the amount of urine that an adult male puts out at one time is assumed to be 250 to 500 cc as a quantity stored in a container 4 to be described later in the water absorbent resin 3 as well as considering compactness and weight reduction. 4g.

  Further, the water-absorbing resin 3 that has gelled by absorbing the water 1 is changed to a liquid state (aggregation of particles of about 2 mm per particle) with 1.5 L of water, and accordingly, if necessary, the gel By making the liquid into a liquid state, it can be discarded and disposed in the toilet.

  In addition, when the present inventor actually conducted a water absorption experiment with 4 g of water absorbing resin 3 for 500 cc of water 1, it was confirmed that the water absorbing resin 3 gels within about 60 seconds.

  The carbonaceous material 2 is rice husk charcoal (carbonized rice husk) as shown in FIG. 1, and usually has graphite attached to the surface thereof, and has an appropriate water repellency that floats when placed in the water 1. . In addition, the specific gravity of the carbonaceous material 2 which concerns on a present Example is 0.08.

  In addition, the carbonaceous material 2 has excellent water floating performance when the moisture content is 20% (weight) or less.

  In addition, the carbonaceous material 2 is a member that hardly absorbs moisture such as moisture, that is, the pores formed on the surface of the rice husk charcoal are, for example, capillary as compared with silica gel used as a moisture absorbent. It is a member with a small distribution of pores of about 2 to 12 μm, which is considered to be a size that easily causes a condensation phenomenon.

  Therefore, even when stored for a long period of time, it is difficult to absorb moisture even in an environment where moisture or the like exists, and therefore, the best water floating performance is always exhibited.

  Moreover, the carbonaceous material 2 exhibits the function which prevents the electrostatic charge in the water absorption resin 3 accommodated in the container 4 mentioned later, and also exhibits the function which prevents the capability fall by adsorb | sucking the moisture at the time of a preservation | save.

  Further, when the carbon material 2 is stored in the container 4, the carbon material 2 is mixed and stored at a volume ratio of 6: 1 with the water absorbent resin 3.

  Specifically, 3.0 g (37.6 cc) of the carbonaceous material 2 is mixed and stored in 4 g (6.3 cc) of the water-absorbing resin 3 described above. In addition, the quantity of the water absorption resin 3 and the carbonaceous material 2 can be changed suitably.

  The charcoal material 2 floating in the water 1 is not limited to rice husk charcoal, but exhibits the characteristics of this embodiment such as charcoal, bamboo charcoal, buckwheat charcoal, coconut charcoal, coffee charcoal, activated carbon, and other carbonized carbon fiber. Anything can be used as appropriate.

  In addition to the carbonaceous material 2 floating in the water 1, a porous material 2 floating in the water 1 can be used. For example, silica gel or zeolite is desirable.

  If the carbon material 2 or the porous material 2 hardly floats in the water 1, an appropriate water repellent treatment is performed so as to float in the water 1.

  In addition to the water-repellent carbon material 2 floating in the water 1, a hydrophilic carbon material (rice husk charcoal) that sinks in the water 1 may be stored together in the container 4.

  The carbonaceous material having hydrophilicity is a treatment that improves the hydrophilicity opposite to the above-described water repellency by preventing the adhesion of graphite that normally adheres to the surface of rice husk charcoal when the rice husk is carbonized. Is going. Its water absorption is 7.57 g / g.

  Specifically, the rice husk charcoal is heated in an oxygen-free or low-oxygen state while stirring in the carbonization processing unit, and when this heat treatment is performed, the gas generated in the carbonization processing unit is forcibly exhausted out of the carbonization processing unit. The hydrophilicity of rice husk charcoal is improved by reducing the graphite content in rice husk charcoal.

  Moreover, you may make it the carbonaceous material 2 which has hydrophilicity have hydrophilicity by surface-active treatment.

  Therefore, the carbonaceous material 2 having hydrophilicity sinks in the water 1 and exhibits an odor adsorption function from the inside. If the water 1 is the water 1 contained in the excrement, the carbonaceous material 2 2 is concealed by being mixed inside, so that it is easy to be disposed of in terms of appearance (visual discomfort is reduced).

  The charcoal material that sinks in the water 1 is not limited to rice husk charcoal but may be activated carbon or the like. In addition, as a member stored in the container 4 together with the carbonaceous material 2 having water repellency that floats on the water 1, silica, zeolite, or the like Any device can be used as long as it exhibits the characteristics of the embodiment.

  The water-absorbing resin 3 and the carbonaceous material 2 according to this embodiment described above are stored by being stored and sealed in a mixed state in a non-venting container 4 as shown in FIG.

  As shown in FIG. 1, the container 4 is a stick-shaped bag (for example, a barrier manufactured by Meiwa Packs Co., Ltd.) made of a planar member (a synthetic resin member that does not have air permeability) having oxygen barrier properties and flexibility. A bag made of nylon / polyethylene, a bag made of polyethylene terephthalate / aluminum / polyethylene), and after storing a predetermined amount of the carbonaceous material 2 and the water absorbent resin 3 from the opening, the opening is sealed (heat-sealed). . When closing the opening of the container 4, the inside of the container 4 may be vacuum-treated or filled with an inert gas depending on circumstances.

  In addition, the container 4 has antistatic properties, and therefore, charging that is a concern when the water absorbent resin 3 is stored in the container 4 can be suppressed.

  Specifically, as a bag material having antistatic properties, for example, a planar member in which an antistatic agent is mixed in a synthetic resin member (plastic) such as polyethylene or polypropylene is employed. In addition, those obtained by coating (coating / laminating) an antistatic agent on the surface of the planar member are also appropriately employed.

  The container 4 is not limited to a bag but may be a box-shaped body.

  Further, as shown in FIG. 6, after the container 4 containing the water-absorbing treatment material is stored in the storage container 6 that does not ventilate, the storage container 6 may be sealed to store the water-absorbing treatment material.

  Specifically, in FIG. 6, the container 4 containing the water-absorbing treatment material and the oxygen scavenger 7 (for example, AGELESS (registered trademark) manufactured by Mitsubishi Gas Chemical Co., Ltd.) are stored in the storage container 6 that does not vent and are stored. After the inside of the container 6 is vacuum-processed, the storage container 6 is sealed.

  The storage container 6 is formed into a bag shape by polymerizing a pair of transparent planar members having oxygen barrier properties and flexibility (synthetic resin members not having air permeability) and sealing the peripheral edges. Is. The term “transparency” as used in this embodiment includes translucency that allows the contents to be observed.

  Therefore, since the storage container 6 is transparent, it is possible to confirm the stored contents such as the container 4, the processing bag 5, which will be described later, and the paper printed for the novelty without opening the storage container 6. In addition, since it is stored in the storage container 6, printing on the stored item will not disappear.

  When the storage container 6 is closed, in some cases, the oxygen scavenger 7 may not be stored and may be simply sealed, or the storage container 6 may be vacuum-treated or filled with an inert gas. Alternatively, a desiccant (for example, Hishi beet (trade name) manufactured by AGC S-Tech Co., Ltd.) may be stored together.

  Further, in this embodiment, in addition to the container 4 containing the water-absorbing treatment material and the oxygen scavenger 7 described above, the two opaque plastic processing bags 5 (45L) are folded in the storage container 6. The processing bag 5 is used as a bag for processing excrement, for example, and the excrement disposed in the processing bag 8 can be processed with the water absorption treatment material of this embodiment. In the container 4 shown in FIG. 6, 8 g of the water-absorbing resin 3 and 3.0 g of the carbonaceous material 2 are mixed and stored.

  Therefore, the storage method described above enables long-term storage in the water-absorbing treatment material, so that the best use state can always be obtained, and the excrement can be treated in an emergency (during a disaster or outdoor activity). This is easy and reliable.

  The water absorption treatment work of the processing object A using the water absorption treatment material according to the present embodiment having the above configuration will be described. The following two water absorption treatment operations are examples of use as a simple toilet during outdoor activities and disasters.

  FIG. 2 shows a case where urine and stool are mixed as the processing object A, and the container 4 containing the processing object A (urine and stool) breaks the container 4 and absorbs water. When processing materials (water-absorbing resin 3 and charcoal material 2) are added and lightly stirred, water 1 contained in this processing object A (urine and stool) is absorbed by water-absorbing resin 3, and powdered water-absorbing resin 3 is gelled. On the other hand, the carbonaceous material 2 floats on the water 1 contained in the processing object A (urine and stool), so that the surface of the water absorbent resin 3 that has absorbed the water 1 (the surface of the processing object A) is the carbonaceous material 2. (See FIG. 3).

  Moreover, FIG. 4 is a case where the stool as the processing target A is processed, and the container 4 is broken into the processing bag 5 containing the processing target A (stool) to absorb the water absorption processing material (the water absorbing resin 3 and the carbon material). When 2) is sprinkled, the water 1 (moisture) contained in the processing object A (stool) is absorbed by the water-absorbing resin 3, and the powdered water-absorbing resin 3 is gelled to form a layer, while the processing object A The surface of the layered water-absorbing resin 3 that has absorbed the water 1 (the surface of the object to be treated A) is covered with the carbon material 2 by floating the carbon material 2 in the water 1 contained in (stool) (see FIG. 5). .

  When this inventor smelled the smell of the processing target A processed in the two water absorption processing operations mentioned above, it has confirmed that the scattering of the smell emitted from the processing target A was suppressed.

  As a mechanism for odor scattering from the processing target A to the surroundings, when the water 1 (moisture) contained in the processing target A evaporates and scatters to the surroundings, the evaporated water 1 contains odorous components together. Although it is due to scattering to the surroundings, the scattering of the odor emitted from the processing object A treated with the water-absorbing treatment material according to the present example is suppressed by the evaporation containing this odorous component. This is because the water 1 that covers the surface of the water-absorbing resin 3 blocks the water 1 from being used as a lid, and the water 1 is sucked into the carbon 2 by the odor adsorption function of the carbon 2.

  Since this embodiment is configured as described above, unlike the above-described conventional example, the water 1 contained in the processing object A can be absorbed in a small amount by the water-absorbing resin 3, so that it is not bulky when stored or carried. Moreover, since it is not bulky after the water absorption treatment, the disposal process can be easily performed, and the surface of the water absorbent resin 3 that has absorbed water is covered with the carbon material 2 by the carbon material 2 floating in the water 1. For example, when the processing object A emits odor such as excrement (urine), vomit, food residue, etc., the carbon material 2 suppresses the odor emitted from the processing object A, and The processing object A is concealed, and an effect such as facilitating disposal of the appearance can be obtained.

  In the present embodiment, since the water-absorbing resin 3 is powdery (or granular), the surface 1 has a large surface area, so that the water 1 contained in the processing object A is absorbed well and exhibits an excellent water-absorbing function. Become.

  Moreover, since the present Example employs rice husk charcoal as the carbon material 2, the cost is low and the mass productivity is excellent, and a good odor adsorbing function is exhibited.

  In this embodiment, since the water-absorbing treatment material is sealed in the non-breathable container 4, a storage state that always exhibits a good function can be obtained.

  Moreover, since the container 4 which has antistatic property is employ | adopted as the container 4 in a present Example, the favorable storage state will be obtained, without the water absorbing resin 3 accommodated in the container 4 being charged.

  In this embodiment, the container 4 containing the water-absorbing treatment material is stored in the storage container 6 that does not vent, and after the inside of the storage container 6 is vacuum-treated, the water-absorbing treatment material is stored by sealing the storage container 6. Therefore, the water-absorbing treatment material can be stored for a long time, and the best use state can always be obtained.

  Next, tests (Test 1, Test 2, Test 3 and Test 4) on the water-absorbing treatment material of this example were performed.

  Test 1 is an odor adsorption performance evaluation test for ammonia gas.

<Test 1>
As a test method, a filter paper in which 0.1 ml of 5% ammonia water is dropped is put in a desiccator, and then a porous material having odor adsorption performance (zeolite, coconut shell activated carbon, coal-based activated carbon, hydrophilic rice husk charcoal, water repellency). The rice husk charcoal) was placed in a desiccator, and the ammonia gas concentration in the desiccator after a certain time was measured. In addition, the weight of each porous material is set to such a weight that the same volume (about 15 cm ³ ) is visually observed based on 1.0 g of water-repellent rice husk charcoal.

  The results are as shown in the table of FIG. In addition, the value of the 0 minute ammonia gas concentration in the table is the value of the ammonia gas concentration measured after leaving only the filter paper to which ammonia water was dropped just before placing the porous material in the desiccator for 1 hour or more in the desiccator. It is.

  In other words, the porous materials used in Test 1 all had a lower ammonia gas concentration as time passed, confirming the odor adsorption effect.

  Test 2 and Test 3 are odor adsorption performance evaluation tests for aqueous ammonia.

<Test 2>
As a test method, each porous material (zeolite, coconut shell activated carbon, water-repellent rice husk charcoal) having odor adsorption performance was put in a beaker containing 200 ml of 0.5% ammonia water, and this was mixed in a desiccator. The ammonia gas concentration in the desiccator after a certain period of time was measured. In addition, the weight of each porous material is set to such a weight that the same volume (about 15 cm ³ ) is visually observed based on 1.0 g of water-repellent rice husk charcoal.

  The results are as shown in the table of FIG. The value of 0 minute ammonia gas concentration in the table is the value of ammonia gas concentration measured after leaving a beaker containing only ammonia water in a desiccator for 2 hours or more immediately before mixing the porous material. is there.

  That is, when zeolite and coconut shell activated carbon were mixed with ammonia water, the numerical value of ammonia gas concentration hardly changed from beginning to end.

  In addition, when water-repellent rice husk charcoal was mixed with ammonia water, the value of ammonia gas concentration decreased from 0 minutes to 60 minutes later, but increased from 60 minutes to 120 minutes later. I'm back.

  This is because zeolite and coconut shell activated carbon immediately sink in ammonia water, and their odor adsorption performance is not exhibited throughout, while water-repellent rice husk charcoal floats in ammonia water and exhibits odor adsorption performance. This is because, after about 60 minutes, it completely submerged in water, and thereafter no odor adsorption effect was obtained.

<Test 3>
As a test method, a water-absorbing resin (2.0 g) and a porous material (zeolite, coconut shell activated carbon, coal-based activated carbon, hydrophilic rice husk charcoal, water-repellent rice husk charcoal) having odor adsorption performance are mixed, The mixture was placed in a beaker containing 200 ml of 0.5% aqueous ammonia, mixed in a desiccator, and the ammonia gas concentration in the desiccator after a predetermined time was measured. In addition, the weight of each porous material is set to such a weight that the volume is about the same (approximately 15 cm) with respect to 1.0 g of water-repellent rice husk charcoal, and hydrophilic husk charcoal (1.0 g, 4.0 g). ) Is for confirming the change when the amount of hydrophilic rice husk charcoal is changed.

  The results are as shown in the table of FIG. The value of the 0 minute ammonia gas concentration in the table is the ammonia gas concentration measured after leaving the beaker containing only ammonia water in the desiccator for 2 hours or more immediately before mixing the water-absorbing resin and the porous material. It is a numerical value. In addition, it takes about 1 minute for water absorption and gelation when water-absorbing resin is added. In order to grasp the ammonia release concentration during this period, the ammonia gas concentration after 2 minutes from the time of water-absorbing resin is also measured.

  That is, in the case of only the water-absorbing resin, the ammonia gas concentration value gradually increases after gelation.

  Further, when the water-absorbing resin and zeolite, coconut shell activated carbon or coal-based activated carbon are mixed, the value of the ammonia gas concentration is gradually increased after the water-absorbing resin is gelled, as in the case of the water-absorbing resin alone.

  When the water-absorbing resin and the hydrophilic rice husk charcoal are mixed, the ammonia gas concentration gradually increases after the water-absorbing resin is gelled, as in the case of the water-absorbing resin alone.

  Further, when the water-absorbing resin and the water-repellent rice husk charcoal are mixed, the numerical value of the ammonia gas concentration is kept low even 120 minutes after the water-absorbing resin is gelled.

  Here, when the point that the hydrophilic rice husk charcoal is different from the water-repellent rice husk charcoal is described, the hydrophilic rice husk charcoal also floats on the water surface after being put into the ammonia water, like the water-repellent rice husk charcoal described later. It becomes like a lid, but this hydrophilic rice husk charcoal absorbs ammonia water before the water-absorbing resin gels, and it absorbs this ammonia water and is in a state like a lid on the surface. This is because ammonia gas is released from the hydrophilic rice husk charcoal. This does not change even if the amount of hydrophilic rice husk charcoal is increased (even if the lid layer is thickened).

  In this respect, the water-repellent rice husk charcoal floats on the water surface after being put into the ammonia water and becomes like a lid. However, the water-absorbing rice husk charcoal has a lower water absorption than the hydrophilic rice husk charcoal, and therefore the water-repellent rice husk charcoal does not absorb water. Before the water-absorbing resin is gelled, the amount of ammonia gas released from the water-repellent rice husk charcoal in a lid-like state is extremely small. In addition, water-repellent rice husk charcoal tends to float instantly in ammonia water, and it is considered that the release of ammonia gas can be suppressed because it easily floats on the water surface before the water-absorbing resin gels and easily forms a lid.

  From the results of the above tests 1 to 3, the water-absorbing treatment material provided with the water-absorbing resin and the porous material is suitable for the treatment of the treatment object A containing moisture, and in particular, the porous material floating in the water-absorbing resin and water. It was confirmed that the water-absorbing treatment material provided with (for example, water-repellent rice husk charcoal) was useful.

  Test 4 is an evaluation test of the usefulness of the antibacterial water-absorbing resin.

<Test 4>
The test method, the water absorbing resin and an antibacterial processed water resin not antibacterial in sterile cups and each 1g collected, stirred with specimen added to the respective the bacterial solution was adjusted to about 10 ⁵ (E. coli) 50 ml 1 and test product 2. Separately, 50 ml of the bacterial solution alone is put into a sterilized cup to make a blank.

  The prepared test product 1, test product 2 and blank were stored in an incubator at 25 ° C., and the number of bacteria was measured after the first start (immediately after adjustment), 60 minutes and 1440 minutes (24 hours). The initial bacterial count was the blank bacterial count immediately after adjustment.

  The result is as shown in the table of FIG. 10, and the number of bacteria in the test product 2 (antibacterial processed water-absorbing resin) is clearly drastically reduced compared to the others.

  From the results of Test 4 above, it was confirmed that the water-absorbing resin subjected to antibacterial processing was useful as the water-absorbing resin constituting the water-absorbing treatment material.

  Therefore, in this embodiment, a water-absorbing resin subjected to antibacterial processing is employed as the water-absorbing resin 3 described above, and a cationic surfactant is sprayed on the resin surface.

  Examples of the cationic surfactant include benzalkonium chloride, benzethonium chloride, cetylpyridinium chloride, hexadecyltrimethylammonium bromide, and decalinium chloride.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
