Description of the Invention: [Technical Field of the Invention] The present invention relates to an antibacterial, deodorizing property, safe operation, moderate initial water absorption speed, and liquid diffusion property for an absorbent article Excellent water-absorbent resin composition. The present invention is an absorbent article produced by using the water-absorbent resin composition and absorbing the absorbent material. [Prior Art] Previously, water-absorbent resins were used for sanitary materials such as disposable diapers, menstrual sanitary napkins, incontinence pads, urine absorbent materials for pets, and accumulation (4) civil engineering: building materials, droplet absorbents, cold-preserving materials, etc. Various fields such as food preservation materials, soil water retention materials, and other agricultural and horticultural items. The absorbent article represented by a disposable diaper or the like has a structure in which a liquid absorption system such as a body fluid is absorbed by a soft liquid-permeable surface sheet (top sheet) disposed on the side in contact with the working body. The liquid-impermeable back sheet (back sheet) is placed on the opposite side of the surface sheet. Usually, the absorbent system is composed of a mixture of a water-absorbent resin and a hydrophilic fiber. For absorbent articles, it is a problem to absorb unpleasant odors when absorbing body fluids, especially urine, blood, sweat, and the like. It is considered that these odors are caused by the bacteria present in the skin and the digestive tract to produce a chemical sputum which decomposes the body fluid component of the body fluid component such as urea or protein, which is decomposed by the enzyme to suppress the occurrence of such odor. An absorbing agent having an odor component adsorbing an odor component such as activated carbon or buddha is disclosed (for example, referring to Patent Document 3 201210508 or the above-mentioned, bacteriostatic bacteria to prevent an increase in the odor of odor over time) A water absorbing agent such as a sterilizing agent such as a salt and a water absorbing resin (for example, refer to Patent Document 3). As another method for suppressing odor generation, it is disclosed that an antibacterial metal such as silver, copper or zinc is supported on an inorganic compound. A composition comprising an inorganic antibacterial agent and a water-absorbent resin (for example, refer to Patent Document 4). Further, in order to suppress the generation of odor, it is disclosed that an antibacterial scaly salt early component and a squama salt can be obtained. When the monomer component is copolymerized and polymerized, the monomer component of the super absorbent resin can be crosslinked and polymerized to form an antibacterial superabsorbent resin (for example, see Patent Document 5). In another aspect, in the case of the absorbent article, when the liquid diffusion property is poor when the body fluid is absorbed, the body fluid is concentrated in a part, and the odor is easily generated. Therefore, in order to improve the liquid diffusibility of the absorbent article, the absorbent body is The water-absorbent resin of the component is also required to have a moderate water absorption speed and excellent liquid-passing performance. [Patent Document 1] JP-A-2001-037805 [Patent Document 2] 曰本特表平丨丨-512946号 [Patent Japanese Unexamined Patent Publication No. Hei No. Hei. No. Hei. No. Hei. No. Hei. [Explanation] The absorbers of the odor component adsorbents such as activated carbon and zeolite disclosed in Patent Documents 1 and 2 have insufficient effects on the decomposition of body fluid components over time and are not sufficient. The water absorbing agent composed of the sputum agent and the water-absorbent resin disclosed in the fourth grade of Salt 201210508 may cause inflammation due to contact of the bactericide with the skin and mucous membrane, and is not safe in terms of safety. Patent Document* Antibacterial agent Because of its high safety, the antibacterial force persists for a long time: it is suitable for sanitary materials, etc. However, the affinity between the inorganic antibacterial agent and the water-absorbent resin is poor, so there is an absorbent article such as a disposable diaper: the antibacterial agent is dusted ( Dust emission), the problem of deterioration of the working environment at the time of manufacture. The antibacterial superabsorbent resin disclosed in Patent Document 5 has an uneconomical disadvantage because the monomer component having antibacterial property is expensive. In the patent documents, the liquid diffusibility of the absorbent article is not considered. It is an object of the present invention to provide an antibacterial's excellent deodorizing performance, which can be operated all at all, and has an appropriate initial water absorption speed for use in an absorbent article. A water-absorbent resin composition excellent in liquid diffusibility in the case of a mouth. Further, an object of the present invention is to provide an absorbent body produced by using the water-absorbent resin composition and an absorbent article produced by using the absorbent body. The present invention is a water-absorbent resin composition comprising a water-absorbent resin and a plant extract of Myrtaceae. The water-absorbent resin composition of the present invention contains an extract of Myrtaceae which is excellent in antibacterial property, high in safety, and liquid-free and dust-free, so that it has excellent antibacterial and deodorizing properties, and can be operated all by females. It has a moderate initial water absorption speed and is excellent in liquid diffusibility in the case of an absorbent article. [Embodiment] The water-absorbent resin composition of the present invention contains a water-absorbent resin and a myrtaceae plant extract. 201210508 The water-absorbent resin may, for example, be a crosslinked product of an acrylate polymer, a crosslinked product of a starch-acrylic acid graft copolymer, a crosslinked product of a vinyl alcohol-acrylate copolymer, or a maleic anhydride. a crosslinked product of polyvinyl alcohol, a copolymer of a parental isobutylene-maleic anhydride, a crosslinked body of an acrylic acid, a saponified product of a vinyl acetate __acrylic acid vinegar copolymer, etc. It is preferred to crosslink the acrylate polymer in terms of absorbing a large amount of water and maintaining the absorbed water in the molecule even if a slight load is applied. In addition, the shape of the water-absorbent resin is not particularly limited, and examples thereof include a spherical shape, a shaped fracture shape, a granular shape, a scaly shape, a short rod shape, and a particle shape such as agglomerated shape, a long rod shape, and the like. Fiber shape, sheet shape, etc. (4) The shape ' is preferably a particle shape from the viewpoint of easy handling. The method for producing the water-absorbent resin is not particularly limited, and examples thereof include a reverse phase suspension polymerization method and an aqueous solution polymerization method. Examples of the above Myrtaceae plant include: Melaleuca sinensis, myrtus, clove, tea tree, green peony (Pimento), eucalyptus (Eucalyptus), lemon nectarine leaf (iem〇nmy... etc. In the myrtle plant, it is preferably eucalyptus for the purpose of being excellent in antibacterial property or safety. Further, the part of the plant for producing the extract is not particularly limited. It is easy to take the leaves and leaves, and it is better to use leaves. The method for extracting extracts from the above-mentioned Myrtaceae plants, for example, can be listed as "fat extraction method", solvent extraction method, steam distillation method 1 尬 尬 ", T, From the standpoint of simplicity or safety, it is preferred to use Α平乂1 main horse water distillation distillation method to 6 201210508 solvent extraction method. The above myrtle plant extracts are usually commercially available, for example It is possible to use eucalyptus oil manufactured by Wako Pure Chemical Industries Co., Ltd. or a reagent manufactured by Sigma-Aldrich Co., Ltd., and the use amount of the above-mentioned Myrtaceae plant extract is preferably 〇_〇 with respect to 100 parts by mass of the above water-absorbent resin. H~4 parts by mass. When the amount of the above-mentioned extract of the Myrtaceae plant is less than 0.001 part by mass, the obtained water-absorbent resin composition cannot achieve an appropriate initial water absorption speed. Further, the water-absorbent resin composition may not be formed. When the amount of the myrtaceae plant extract used exceeds 4 parts by mass, the obtained water-absorbent resin composition cannot achieve an appropriate initial water absorption rate. The odor of the extract itself may not be supplied. The above-mentioned extract of Myrtaceae plant is preferably used in an amount of 5 to 3 parts by mass, and more preferably 0. (Π~2 parts by mass, especially Preferably, the water-absorbent resin composition of the present invention is such that the extract of Myrtaceae is directly attached to the water-absorbent resin, and the water-absorbent property is obtained in the vicinity of the peach. The resin composition is given a moderate amount. The water absorption resin composition of the present invention is preferably attached to the surface of the water absorbent resin, for example, by the following methods (a) to (c). 'But the water-absorbent resin composition of the present invention is not limited to those manufactured by the above methods. A method of directly mixing the water-absorbing resin with the honey-stained plant extract. (1) Spraying the myrtle with a water-absorbent resin spray Water for plant extracts 201210508 Loose or alcohol solution, and drying method (c) Adding water-absorbent resin and extract of Prunus triloba in a solvent that does not swell the water-absorbent resin, stirring and mixing to remove the solvent In the present invention, the reason why the liquid diffusibility of the absorbent article is improved by using the water-absorbent resin composition containing the water-absorbent resin and the myrtaceae extract is not described in detail, but it is presumed to be based on the following reasons. When the water-absorbent resin composition is actually used for an absorber of an absorbent article such as a disposable diaper, a large amount of the water-absorbent resin becomes a soft gel-like state due to absorption of the liquid, and a so-called "gel blocking phenomenon" occurs. The liquid diffusibility of the absorbent article is significantly reduced. The term "claying phenomenon" refers to a phenomenon in which a water-absorbent resin existing in the vicinity of the surface layer absorbs a liquid, and a soft gel in the vicinity of the surface layer is further densified, thereby preventing penetration of the liquid into the inside of the absorber, and the internal water-absorbent resin cannot Efficiently absorb liquid. It is presumed that the water-absorbent resin composition of the present invention contains a hydrophobic Myrtaceae plant extract, and the water-absorbent resin composition is compared with the initial water absorption rate of the water-absorbent resin before the extract of the Myrtaceae plant. The water absorption speed at the initial stage of the object is slow, and as a result, the cementation phenomenon is prevented, and the liquid diffusibility of the absorbent article is improved. The initial water absorption speed of the water-absorbent resin composition is preferably from 2 to 35 seconds. When the initial water absorption speed is less than 20 seconds, the phenomenon of suppressing the liquid diffusibility in the case of the absorbent article, that is, the cementation phenomenon, may not be prevented. If the initial water absorption rate is more than 35 seconds, the amount of back bleed of the liquid for the case of the absorbent article may not be reduced. The initial water absorption speed is preferably 22 to 30 seconds 〇 8 201210508 Further, the initial water absorption speed is obtained by the following operation.
