[Technical field to which the invention belongs]

 The present invention relates to a deodorizing and water-absorbing material capable of instantly deodorizing various malodors and absorbing moisture, and a household article having a deodorizing and water-absorbing function using the deodorizing and water-absorbing material.

[0002]

[Prior art]

 In general, "ammonia", "hydrogen sulfide", "trimethylamine", and "mercaptan" are well known as bad odor sources, and these are molecules that cause putrefaction odor, for example, from sewage, sludge, filth, or animal corpses. These are accompanied by moisture. In other words, moisture contains molecules that emit odor, and in such a case, it is necessary to treat both the moisture and the odor at the same time. There are many treatments, such as the treatment of the crude phase of elderly and indoor pets, diapers for infants or the elderly, and women's sanitary products.

Until now, as a response to the above demands, porous materials such as activated charcoal (charcoal, coconut shell charcoal, coffee charcoal, okara charcoal, rice charcoal, tea charcoal) and zeolites have been used to reduce malodorous molecules. Attempts have been made to eliminate odors by physically taking them into the pores, or to eliminate odors by masking the odor with the strong smell of the fragrance. It did not say that it did not have the deodorizing effect as expected, and porous materials such as activated carbon and zeolite and fragrances do not absorb water, so they are ineffective against odorous odors with odor. there were.

[0004]

[Problems to be solved by the invention]

 The purpose of the present invention is to develop a material that satisfies both of these uses, that is, water absorption and deodorization, and to develop an applied product.

[0005]

Means for Solving the Problems Claim 1 relates to the deodorant and water-absorbing material (A) of the present invention, wherein "the core material is composed of the water-absorbing polymer powder (1), The deodorant fine powder (2) containing at least one essential oil or extract or a mixture of two or more of the fruits as an active ingredient adheres to form a deodorant layer. "

[0006] According to this, since the water-absorbing polymer particles (1) are used as the core material, water can be absorbed, and the deodorant fine powder (2) adheres to the surface thereof. Therefore, the odor contained in the water can be eliminated. In addition, since the deodorant fine powder (2) contains at least one essential oil or extract or a mixture of two or more of plants and fruits as an active ingredient, it has a high porosity such as activated carbon or zeolite as described above. It is neither physical adsorption by substances nor masking by fragrances, but decomposes odor molecules themselves into molecules of odorless amino acids, so that odors can be eliminated from the source and extremely effective deodorization is achieved. I can do it. It is also possible to add a subtle citrus fragrance such as cypress or orange by selecting deodorant components. In this case, for example, put the deodorant and water-absorbing material (A) in a sprinkling container and sprinkle the deodorant and water-absorbing material (A) from above when a child spills urine outside the toilet in the toilet. Therefore, urine spilled on the floor can be absorbed into the water-absorbing polymer powder (1) as a core material at once, and the odor of urine can be eliminated by the deodorant fine powder (2) on the surface layer. It makes it easier to clean the floor later.

[0007] "Claim 2" is an example using the deodorizing and water absorbing material (A) according to "Claim 1".

"

The flexible water-absorbing layer (3) is a portion where water absorption and deodorization are performed, in which a non-woven fabric (3a) such as cotton or pulp carries a deodorizing and water-absorbing material (A). The non-woven fabric (3a) first contained the water-absorbing polymer powder as the core material (1) of the deodorant and water-absorbing material (A), which absorbed water and swelled, and was included in the non-woven fabric (3a). Quickly absorbs all of the water. Further, the deodorant fine powder (2) of the deodorant and water-absorbing material (A) in the flexible water-absorbing layer (3) decomposes the malodorous molecules emanating from the water by the above-mentioned action and deodorizes it.

The flexible waterproof layer (4) is composed of a thin and flexible resin film or a waterproof and thin and flexible paper, and the moisture contained in the flexible water-absorbing layer (3) is made of a core material. (1) Prevents leakage to the outside before being absorbed by the water-absorbing polymer powder. The flexible surface layer (5) is a thin and flexible piece of paper or woven fabric, which is the part that appears to the outside. The whole of these laminates (S) is sufficiently flexible and does not cause much discomfort when applied to the skin.

[0010] Claim 3 is one of the specific examples of the household article (B) having a deodorant and water-absorbing function according to claim 2, wherein "the sheet-like flexible water-absorbing side layer (3) comprises: The sheet-like flexible surface layer (5) is integrally laminated at the approximate center of the sheet-like flexible waterproof layer (4) via a flexible waterproof layer (4). '' It is used for seats and indoor pet toilet rugs.

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail with reference to examples. The deodorant fine powder used in the present invention is obtained by distilling, extracting, vacuum-distilling or vacuum-distilling or extracting alcohol from leaves, stems, trunks (bark and its woody parts) or roots and fruits (including bark and seeds) of plants. The obtained one essential oil or extract (hereinafter, referred to as phytontide) or a mixture of at least two or more thereof is used as an active ingredient. For example, it is impregnated with a porous fine powder and dried to form a powder. .

[0014] The "phytoncide" volatilizes or retains a certain component in order to protect a plant from microorganisms and insects that harm the plant, and exhibits a bactericidal action and an insect repellent effect. Terpenes are known to be the main components, but not all of the constituents are known.

The “phytoncide” used in the present invention is obtained by subjecting a target material to vacuum distillation or alcohol extraction. To introduce one of the extraction examples, put the leaves, stems or trunks (bark and its woody parts), roots and fruits (including skins and seeds) of the above-mentioned plant in a pressure vessel, add water and add about 120 ° C. When heated at a temperature of, the oil contained in the extracted material is extracted. The extract was cooled, and the supernatant was taken out from the extract.

[0016] The components constituting "phytoncide" contained in the above-mentioned plants and fruits differ from plant to fruit and from plant to fruit. For example, various types of terpenes, hinokitiols are included in cypress leaves and their materials and hiba and their materials. These include luster oil, flavone, and cedarwood oil. Kuromatsu and its materials and fir-leaf contain terpenes, and fir-leaf contains cool-leafed leaf oil. In addition to terpenes, cedar leaves and cedar leaves contain cedar oil and other materials. In addition, n-hexane, ether, acetone, methanol and the like are included. Tea leaves have a bactericidal effect by catechin, and extracts of Kumasa-basa leaves and their fruits and their stems also have a bactericidal effect. Of course, the present invention is not limited to the above components and functions, and it is expected that unknown components and functions also exist. The following cases are also examples.

[0017] Volatile components contained in certain "phytontides" are liable to vaporize, and among them, volatilize in the air and combine or decompose in the air with the malodorous molecules in the air to form odorless amino acids. There are components to change. However, at this time, no component that converts malodorous molecules into odorless amino acids has not been identified. However, "Kuromatsu and its materials, Hinoba and its materials, Sugi and its materials, Foliage and Hiba and its materials, Kumasaba And its fruit, its stem, Yaku cedar wood, camellia leaf, persimmon leaf and its fruit, Kusunoki leaf and its fruit, orange and its stalk and grape seed, and its effect is strongly exhibited by a mixture of one or more of "phytoncide". Was found in the experiment.

In the present invention, the above-mentioned “Kuromatsu and its materials, Hinoki and its materials, Cedar and its materials, Mochiha, Hiba and its materials, Kumasasa and its fruits and its stems, Yakusugi, Camellia and persimmon leaves A deodorant fine powder (2) in which a mixture of one or more phytoncides of berries, camphor leaves and berries, oranges and their stalks and grape seeds is supported on a porous fine powder is used as a water-absorbing polymer powder (1). ).

The water-absorbing polymer powder (1) is called an acrylic acid polymer metal salt, and has a chemical structure represented by (C ₃ H ₄ O ₂ ) n · XNa, which absorbs water. It swells and acts to prevent the absorbed and fixed moisture from escaping. The optimal particle size of the water-absorbing polymer powder (1) is selected depending on the application. Since the deodorant fine powder (2) is attached to the surface of the water-absorbing polymer powder (1), the water absorbed by the water-absorbing polymer powder (1) contains the odor-producing components. However, even if an attempt is made to release a bad odor from the surface of the water-absorbing polymer particles that have swollen by absorbing the water, the deodorant fine powder (2) on the surface of the water-absorbing polymer particles (1) removes the malodor molecules. Immediately decomposes into odorless amino acids and blocks odor from the water-absorbing polymer powder (1). When used in the form of a deodorant and water-absorbing material (A), for example, put it in a sprinkling container and put it in the deodorant and water-absorbing material (A), and when a child spills urine out of the toilet in the toilet, deodorize from above Sprinkling the water-absorbing material (A) allows the urine spilled on the floor to be absorbed into the water-absorbing polymer powder (1) as a core material at some point, and the deodorant fine powder (2) on the surface layer The odor of urine can be eliminated and the floor can be easily cleaned later.

FIG. 2 shows a first example of the use of the deodorant and water-absorbing material (A) in which the deodorant fine powder (2) is attached to the water-absorbing polymer powder (1). It is a sheet for nursing care of a bedridden elderly person (B1). The nursing care sheet (B1) is made of a water-absorbing woven or nonwoven fabric, and a rectangular sheet-like flexible water-absorbing side layer (3) carrying a deodorant and water-absorbing material (A) is used as the sheet-like flexible sheet. It is laminated integrally at the approximate center of the surface layer (5) via a sheet-like flexible waterproof layer (4). It is used for nursing care of the elderly, as a protective sheet when laying on a futon for infants, or as a rug for indoor pet toilets.

FIG. 3 shows a second use example of the deodorant and water-absorbing material (A), which is used for a sanitary article (B2). Flexible surface layer formed of flexible paper formed into a rectangular or substantially bar-shaped (5) Water-resistant paper or sheet-like flexible waterproof layer formed of a flexible thin resin at approximately the center of (5) A sheet-like flexible water-absorbing side layer (3) made of cotton, pulp or the like carrying the deodorant and water-absorbing material (A) is integrally laminated via (4).

Conventional sanitary products only carry the water-absorbing polymer particles, so there was no problem in absorbing and fixing the liquid portion, but the problem of odor was not solved. However, in the present invention, since the deodorant and water-absorbing material (A) in which the deodorant fine powder (2) is adhered to the water-absorbent polymer powder (1) is used, the above-described action allows the use of the used sanitary products. The odor is completely decomposed and becomes odorless. Although the structure of sanitary products varies widely, the location of the deodorant and water-absorbing material between the surface mesh sheet and the body that comes into contact with the human body is the most easily absorbed and the performance is easily exhibited.

FIG. 4 shows a third example of the use of the deodorant and water-absorbing material (A), which is used for a diaper for children or the elderly or adults. The functional surface layer (5) is formed into a pants-like shape, and a sheet-like flexible water-absorbing side layer (3) is provided inside the crotch (6) via a sheet-like flexible waterproof layer (4). They are integrally laminated. Therefore, even if the wearer has a rough phase, the water-absorbing polymer powder (1) absorbs moisture, and the odor is immediately deodorized by the deodorant fine powder (2).
