Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deodorizing composition having dehumidifying properties.
It is well known that it is used in applications such as closets and foot boxes for absorbing moisture. However, this product does not have the ability to actively deodorize the environment in which it is placed. On the other hand, an adsorption carrier carrying a stabilized chlorine dioxide solution or powdered stabilized chlorine dioxide that is effective for deodorizing purposes is, for example, the deodorizing composition (Japanese Patent Laid-Open No. 57-11100) that the present inventor previously applied for. −
No. 57550, No. 57-59634, No. 57-156
No. 768, etc.), these have a great deodorizing function but have a drawback of having a low ability to adsorb moisture in the environment. Furthermore, the moisture-absorbing sheet (Japanese Patent Application Laid-open No. 153736/1983), which has a deodorizing ability and was previously applied for by the present inventor, can be used in cases where it comes into direct contact with objects such as shoe insoles, diapers of incontinent patients, etc. When placed in an airflow path, it can have both deodorizing and dehumidifying effects, but it is not suitable for foot boxes.

Just leaving it in a humid place such as a closet will not increase its ability to absorb moisture.

The present invention was made in view of the current state of the above-mentioned known products and prior art, and its purpose is to perform both dehumidification and deodorization functions by leaving the product in a humid place. It is an object of the present invention to provide a deodorizing composition with heat removing properties. Furthermore, another object of the present invention is to provide the deodorizing composition of the prior application ( The object of the present invention is to obtain a new and improved deodorizing composition having an added dehumidifying function.

The present invention is characterized by a solid adsorption carrier carrying a stabilized chlorine dioxide solution that gradually releases chlorine dioxide into the air, or a powdered stabilized chlorine dioxide containing calcium chloride and a high This is because it contains a water-absorbing compound such as a water-absorbing resin.

Hereinafter, the present invention will be described in detail. As the solid adsorption carrier used to support the stabilized chlorine dioxide solution used in the present invention without stirring, examples include inorganic compounds such as alumina, calcium silicate, diatomaceous earth, or methyl cellulose. Examples include various cellulose compounds such as , and organic compounds such as super absorbent resins, and these may be used alone or in combination of two or more.

Among these, powders or granules of alumina, calcium silicate, or super water-absorbing resins, which have a high water-carrying capacity, are preferably used. The concentration of the stabilized chlorine dioxide solution to be adsorbed and supported on these adsorption carriers is 100 to 50,000 ppm,
Preferably, the content is in the range of 500 to 10,000 ppm. If the concentration is less than 100 ppm, the deodorizing effect will be poor, and if the concentration exceeds 50,000 ppm, the odor of chlorine dioxide itself will be felt, which is outside the scope of the present invention. In addition, the quality of the stabilized chlorine dioxide solution to be adsorbed and supported on these adsorption carriers should be determined depending on the adsorption capacity of the adsorption carrier, the use of the deodorizing composition of the present invention, etc.
Generally, 10 to 10% of stabilized chlorine dioxide solution is
300% heavy view is suitable. It is preferable to avoid amounts outside of this range from the viewpoint of sustainability of the deodorizing effect or adsorption capacity of the carrier. Furthermore, in the present invention, powdered stabilized chlorine dioxide can be used in place of the adsorption carrier on which the stabilized chlorine dioxide solution is supported, but this is achieved by adsorbing chlorine dioxide onto an inorganic peroxide or the like during the manufacturing stage. It is a stabilized compound, and as a commercially available product, Biotalk powder (trade name manufactured by Sukegawa Chemical Co., Ltd.)
Alternatively, Iodorid powder (manufactured by Biocide Chemical Co., USA, trade name) can be suitably used.

Next, as the calcium chloride used in the present invention, calcium chloride having water of crystallization such as anhydrous salt or dihydrate salt can be used, but it is preferable to use an anhydrous salt from the viewpoint of water absorption ability.

The particle size is preferably granular rather than lumpy in order to achieve uniform mixing of each component of the composition.

Regarding the super-absorbent resin and water-absorbing inorganic compound that are the components of the deodorizing composition of the present invention, the super-absorbent resin includes, for example, a starch-acrylic graft polymer, a cross-linked polyvinyl alcohol polymer, or an intramolecularly cross-linked polymer. Examples include powders or granules of organic polymers such as polyethylene oxide. All of these have the property of absorbing 100 to 500 times their own weight of water. In the present invention, the significance of blending a super absorbent resin and/or a water absorbing inorganic compound (hereinafter abbreviated as super absorbent resin, etc.) is as follows. That is, the dehumidifying deodorizing composition of the present invention is
On the one hand, chlorine dioxide is gradually released into the environment from the adsorption carrier carrying the stabilized chlorine dioxide solution, thereby exerting a deodorizing effect, and on the other hand, the blended calcium chloride removes moisture from the environment. Since it has the effect of dehumidifying water vapor), compositions that do not contain superabsorbent resin etc. gradually increase their moisture content as they are used over time.
Eventually, the entire composition became sticky and water oozed out of the packaging material, such as a non-woven bag. To prevent this, a material is required that further adsorbs the moisture absorbed by calcium chloride and prevents the entire composition from becoming sticky, and superabsorbent resins and the like are blended for this purpose. Therefore, a material with a sufficiently large amount of water absorption, such as a superabsorbent resin, is used as the adsorption carrier for supporting the stabilized chlorine dioxide liquid, and this superabsorbent resin has a surplus water adsorption capacity, and the amount of calcium chloride contained in the superabsorbent resin is If the amount is not large, the superabsorbent resin that acts as an adsorption carrier for the stabilized chlorine dioxide solution can also serve as the above-mentioned stickiness prevention function, so it can be omitted to add additional superabsorbent resin etc. .

Next, examples of water-absorbing inorganic compounds include compounds that can support absorbed water, such as alumina, silica, diatomite, Kanuma soil 1 synthetic calcium silicate, zeolite, and clay. Synthetic silicic acid lucicum and alumina, which have a large potential, are preferably used.

These water-absorbing inorganic compounds may be used alone or in combination with the superabsorbent resins described above.

In the present invention, the quantitative ratio of each of the above-mentioned components is as follows:
~600% by weight and 1~100% by weight of super absorbent resin, etc., and the reason why these quantitative ratios were specified is as follows. First of all, with regard to calcium chloride, if the amount used is less than 50% by weight, the effective period of the dehumidifying ability is short, so although the deodorizing effect continues, only the dehumidifying ability is saturated and disappears. In addition, if the amount exceeds 600% by weight, moisture absorbed at the end of use may be absorbed by nonwoven fabrics such as nonwoven fabrics. The composition of the present invention is difficult to use for applications such as inside shoes and sports bags because it oozes into packaging materials such as, and the composition of the present invention continues to have deodorizing ability even though its deodorizing ability has decreased. It is excluded from the present invention because it causes an imbalance in the effects. Next, regarding super absorbent resin etc., 1
An amount less than 100% by weight is insufficient to prevent the composition from becoming sticky at the end of use, and an amount exceeding 100% by weight is an excessive amount to prevent the composition from becoming sticky. It's outside.

The dehumidifying and deodorizing composition of the present invention may be colored with an appropriate coloring agent or numbered by adding a liquid or solid fragrance.

In order to obtain the deodorizing composition of the present invention, first, a stabilized chlorine dioxide solution is added to the above-mentioned adsorption carrier by a method such as dropwise addition to adsorb it, and an adsorption carrier on which the stabilized chlorine dioxide solution is supported is prepared.
A predetermined amount of calcium chloride, a super absorbent resin, etc. are added to this adsorbent or powdered stabilized chlorine dioxide, and the mixture is uniformly mixed using a stirring device such as a kneader to obtain the deodorizing composition of the present invention. .

The dehumidifying and deodorizing composition of the present invention adsorbs moisture in the air to dehumidify it and also deodorizes odors in the environment through the oxidizing action of stabilized chlorine dioxide. Alternatively, store the nonwoven fabric in a breathable bag such as a sheet that is breathable but does not allow liquid to pass through, for example, in a cupboard.
Deodorizing and dehumidifying places where moisture tends to accumulate, such as foot boxes, closets, washrooms, toilets, hospital rooms, etc., dehumidifying and deodorizing the inside of shoes, lockers, and sports bags, and preventing mold and odor from animal carcasses for medical use. It is highly useful as it has effects not found in conventional products and can be used for various purposes such as prevention of mold growth, as well as anti-mold and moisture-proofing of dried and preserved foods.

Examples will be shown below, in which parts and percentages are by weight, respectively.

Example 1 500 pp to 100 parts of 3 to 4% y of alumina silica spheres (trade name: Neobead, manufactured by Mizusawa Chemical Industry Co., Ltd.)
10 parts of a stabilized chlorine dioxide solution (one part name: Biotalk, manufactured by Sukeyo Kagaku Co., Ltd.) is added and adsorbed to obtain an adsorption carrier carrying a stabilized chlorine dioxide solution. This adsorbent 10
0 parts, 50 parts of chloride salt granules (manufactured by Wako Pure Chemical Industries, Ltd.) and 1 part of superabsorbent resin granules (trade name Sumikagel 5-50, manufactured by Sumitomo Chemical Industries, Ltd.) were mixed. A dehumidifying deodorizing composition of the present invention was obtained. This composition 3
When 0 parts were stored in a bag made of a polypropylene sheet (product name: NF Receipt Tokuyama Soda Co., Ltd.) that is breathable but not permeable to liquids and placed inside leather shoes, it was found to be effective in deodorizing and removing odors inside leather shoes. It was especially effective in dehumidifying after wearing it in rainy weather. The effect lasted for about 1 month.

Example 2 Super water absorbent resin powder containing crosslinked polyacrylic acid polymer as main component (trade name: Aqua Keep 103H).

100 parts of synthetic calcium silicate powder (product name 70-Light R, manufactured by Tokuyama Soda Co., Ltd.)
After uniformly mixing 100 parts of a commercially available 10,000 ppm stabilized chlorine dioxide solution (100 parts of calcium chloride anhydrous from BioPoid, Inc., USA) with 80 parts of the mixture, the mixture was placed in a breathable non-woven bag and placed in a closet for about 1.2 d. The composition of the present invention continued to have moldiness prevention and dehumidification effects for about two months, and no water leakage into the nonwoven fabric bag was observed.

In this example, since the superabsorbent resin supporting the stabilized chlorine dioxide solution has sufficient water adsorption capacity,
This is thought to prevent stickiness caused by the absorption of water by Lucicum chloride, and is cited as an example of the description that the additional mixing of the superabsorbent resin and the like described above can be omitted.

When 200 copies of these were wrapped in washi paper and placed in a breathable plastic dormitory with an open top, they were used in the bathroom of a coffee room in the basement, and they were effective in eliminating mustiness and other odors. It was found that the relative humidity was reduced by about 5 to 10% compared to when it was not used, and it was found to be highly effective in dehumidifying and deodorizing.

Example 4 100 parts of the super absorbent resin used in Example 2 was added at a concentration of 5.
800 parts of a stabilized chlorine dioxide solution of 000' ppm was added for adsorption. To 100 parts of this adsorbate were added 800 parts of granular chloridic anhydride, 50 parts of alumina powder (manufactured by Mizusawa Chemical Industry Co., Ltd.), and 50 parts of the superabsorbent resin granules used in Example 1, and mixed.

When 200 parts of the composition of the present invention thus obtained was stored in a non-woven bag and placed in a plastic container equipped with a grid-like ventilation hole, it was placed near an indoor sandbox for pet cat excrement and urine. The odor was prevented for two months.
