[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows the basic configuration of the present waste function-equipped filth container. The present device is largely composed of a manure storage site 1 and a notification site 2. The manure storage site may be a manure absorption site or a manure storage site. The notification site 2 is not particularly limited as long as it provides a signal or information by receiving a signal (electricity) from the manure storage site 1.
It is possible to notify a third party that the defecation urination has been performed using the light, lamp (light), image (display display), and operation (various actuators: motors, etc.).
The notification site 2 may be directly connected to the manure storage site 1 or may be provided at a remote location via a signal line (electric wire). For example, in the case of a hospital, patients can be
Alternatively, a cable may be drawn from the indirectly disposed excrement accommodating site to the nurse station so that the nurse can be notified that the patient's defecation urination has been performed. Alternatively, as shown in FIG. 2, the excrement accommodating site 1 and the reporting site 2 are configured to be detachable, and the excrement accommodating site 1 is discarded after use, while the reporting site 2 is used repeatedly. You may do it.

[0007] The manure storage site 1 preferably has a structure capable of absorbing and storing feces and urine after defecation and urination, and is usually absorbed by paper, cloth, synthetic fibers, and various manure absorbents. Alternatively, they may be temporarily stored in a plastic, glass (bin), metal, or inorganic (seto) container (see FIG. 3). In the present invention, by providing at least two or more types of electrodes having different ionization tendencies (not shown) in the feces and urine storage site, an electromotive force can be generated when feces and urine are absorbed / stored in the same site. Usually, feces and urine are composed of an aqueous electrolyte solution containing salt, etc.
For example, if you immerse a copper plate and a zinc plate, the copper pole will be positive,
The zinc electrode becomes negative, causing electromotive force. The notification part 2 is connected to this.

As the liquid absorbing resin 5 used in the present invention, a water absorbing resin can be used. For example, starch graft-based resins (starch-polyacrylic acid-based, starch-polyacrylonitrile-based), cellulose graft-based resins, polyacrylate-based resins, polyvinyl alcohol-based resins, polyacrylamide-based resins, polyoxyethylene-based resins, and polyoxyethylene-based resins N-alkylacetamide resin, poly
N-alkylformamide resin, polyamino acid resin,
Examples thereof include isobutylene-maleate resin, cross-linked CMC resin, and the like. These may be used alone or in a mixture of two or more. The liquid absorbent resin is preferably mixed in a sheet in which paper, cloth, synthetic fiber, and the like are manufactured (see FIG. 3).

When the absorption of manure is absorbed by the liquid absorbent resin described above, the electrolyte component originally present in the resin and the electrolyte contained in the manure become a medium, and a current flows between electrodes having different ionization tendencies. Will be promoted.
In addition, by using the following electrolytic solution absorbing resin as the liquid absorbing resin, it is possible to further improve the current value in the liquid absorbing gel. This electrolytic solution-absorbing resin can be produced by using a water-insoluble polymer obtained from an inexpensive general-purpose monomer shown below as a raw material and introducing a hydrophilic polar group into it.

Examples of the water-insoluble polymer include ABS polymer, high impact polystyrene (HIPS), styrene-butadiene elastomer (SBC), SAN (styrene-acrylonitrile) polymer, polyacrylonitrile polymer (PAN), and polyacrylonitrile-butadiene (nitrile). Rubber), polystyrene (PS), nylon polymer, polyolefin (polyethylene, polypropylene, polyisoprene) polymer, vinyl chloride (PVC), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polycarbonate (PC), polyethylene terephthalate (PET) , Polybutylene terephthalate (PBT), polysulfone, polyallyl sulfone, polyether sulfone, polythioether sulfone, polyether -Terketone, polyetherimide, polyetheretherketone, polyamide (nylon), polyamideimide, polyimide, polyarylate, aromatic polyester, polyurethane, polyvinyl chloride, chlorinated polyether, polychloromethylstyrene, polyacrylate, polymethacrylic acid Ester, celluloid, various liquid crystal polymers, methacrylic polymer (PMMA), amber polymer, terpene polymer, epoxy polymer, phenol-formalin polymer, melamine polymer and the like can be mentioned. Those having an easily introduced aromatic ring or conjugated diene structure are more preferable. The content of the aromatic ring and / or conjugated diene unit in the water-insoluble polymer is desirably 1 to 100 mol% based on all units in the polymer. If the content is lower than this, the number of hydrophilic polar groups introduced into the water-insoluble polymer decreases, and the absorption effect on the electrolyte may decrease.

The molecular weight of the water-insoluble polymer material (M
The weight average molecular weight (M) is not particularly limited as w).
w) is between 1,000 and 20,000,000, and even 1
It is generally between 000 and 1,000,000. If the molecular weight is lower than this, the gel is completely dissolved in the electrolyte solution due to the introduction of the hydrophilic polar group, and the gel state cannot be maintained after absorption. If the molecular weight is higher than this, it is difficult to introduce a hydrophilic polar group, which is not practical.

[0012] These water-insoluble polymers may be newly produced virgin pellets, used in the production of polymer raw materials or molded products (semi-products), or used in electric products and automobiles. A used waste material formed for a specific use from a molded housing or various component materials, or a tube, a hose, or various cushioning materials may be used. The place of discharge may be from factories, stores, households, etc., but those collected from factories, stores, etc. have relatively more composition than general waste from households, etc. More desirable because there are many things. The water-insoluble polymer may be an alloy with another polymer, and may be a waste material containing additives such as a facial dye, a stabilizer, a flame retardant, a plasticizer, a filler, and other auxiliary agents. May be. Alternatively, a mixture of used waste material and virgin material may be used.

An electrolyte-absorbing resin can be produced by introducing a hydrophilic polar group into the above-described water-insoluble polymer. At this time, the hydrophilic polar group increases the absorbability to the electrolyte. On the other hand, the hydrophobic portion (the main chain, the aromatic ring and the portion into which the hydrophilic polar group is not introduced) in the water-insoluble polymer is used to prevent the polymer from being dissolved in various electrolyte solutions. The effect is as follows.

The hydrophilic polar group includes a polar group such as an acidic group or a basic group. The acidic group or the basic group may form a salt. Specifically, such a hydrophilic polar group forms a salt represented by the formula —SO ₃ M (where M represents a hydrogen atom or a cation such as a metal such as sodium and potassium). An optionally present sulfo group, formula-

Preferably, the water-insoluble polymer having an aromatic ring is directly reacted with a sulfuric acid such as concentrated sulfuric acid (more preferably about 70% by weight or more), sulfuric anhydride, fuming sulfuric acid, chlorosulfonic acid and the like. Alternatively, the polymer is dissolved or dispersed in an organic solvent and reacted with a sulfonating agent to introduce a sulfo group. Subsequently, the polymer is converted to a basic substance (for example, sodium hydroxide or potassium hydroxide, etc.). ), It is possible to convert to a sulfonate. The reaction temperature at the time of sulfo group introduction greatly differs depending on whether or not an organic solvent is used.
To about 200 ° C., preferably about 30 to 120 ° C. When the temperature is about 0 ° C. or higher, the reaction rate becomes sufficiently high, and an electrolytic solution-absorbing polymer having better performance can be obtained. On the other hand, when the temperature is lower than about 200 ° C., the molecular chains in the polymer are hardly cut, and the polymer is hardly dissolved in water or a solvent. The reaction time varies greatly depending on the reaction temperature, but is generally about 1 minute to 40 hours, preferably 5 minutes to 2 hours. Under these conditions, the reaction proceeds more sufficiently and the production efficiency is good.

As a method for introducing a sulfate group which may form a salt, preferably, a sulfate group is first introduced by reacting a water-insoluble polymer having an unsaturated bond with an aqueous sulfuric acid solution at a high temperature. By reacting with a basic compound (eg, sodium hydroxide or potassium hydroxide), a sulfate can be obtained. As a method for introducing a carboxyl group which may form a salt, preferably, n-butyllithium is added to a water-insoluble polymer having an aromatic ring, and then the carboxyl group is first reacted with dry ice.

As a method for introducing a hydroxyl group which may form a salt, preferably, a hydroxyl group can be first introduced by reacting a water-insoluble polymer having an unsaturated bond with an aqueous sulfuric acid solution. The same salt can be obtained by reacting with a compound (for example, sodium hydroxide or potassium hydroxide). Level 3 and / or
Alternatively, as a method for introducing a quaternary amine base, preferably, a water-insoluble polymer having an aromatic ring is subjected to chloromethylation by a Friedel-Crafts reaction, and then reacted with ammonia or various amine compounds. Tertiary and quaternary amine salts can be introduced as ionic groups.
Introduction of a primary amino group or a secondary amino group, and conversion of these amino groups into salts may be carried out according to a method known per se.

The hydrophilic polar group-introducing agent or basic substance may be a virgin agent, a waste liquid discharged from a factory, or a recycled product. From the viewpoint of effective utilization of resources, it is more preferable that the waste liquid is used as a raw material of the electrolyte absorbing polymer. In addition, only one type of these hydrophilic polar groups may be introduced into the water-insoluble polymer, or two or more types may be introduced. Further, the amount of these hydrophilic polar groups introduced into the water-insoluble polymer is preferably about 0.1 to 99 mol% with respect to all units in the polymer. The above range is preferable in order to prevent the polymer after the introduction of the hydrophilic polar group from being dissolved in water, and to have a good absorbability to the electrolytic solution.

The electrolyte absorbing resin obtained by the above-described method may be further subjected to a treatment known per se. According to a preferred embodiment, the reaction product, which is usually a gel, obtained by the above-described hydrophilic polar group introduction reaction is preferably filtered, washed with water, and then dried or dehydrated to obtain various types of excellent electrolysis. A polymer having a liquid absorbing ability is obtained. In addition, it goes without saying that the electrolytic solution-absorbing resin of the present invention may be produced by polymerizing a monomer having the above-mentioned hydrophilic polar group introduced into the main chain and / or side chain according to a means known per se.

The electrolyte-absorbing resin of the present invention may optionally contain other components, for example, a conventionally known electrolyte-absorbing resin (eg, a polymer obtained by adding a crosslinking monomer), a stabilizer, a moisture absorbing agent, a curable type. An adhesive or the like may be further added.
