Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an indoor tatami mat,
Removes allergens such as dust, dust, mites (including carcasses and feces), pollen, mold, and pet hair that exist in minute and complicated gaps, depressions, grooves, etc. of objects to be treated such as floors and rugs And an allergen removing method using the same.

[0002]

BACKGROUND OF THE INVENTION Currently, bronchial asthma, atopic dermatitis,
The frequent occurrence of allergic diseases such as hay fever has become a major social problem. Known substances (allergens) for these allergic diseases include dust, dust, mites, pollen, mold, and pet hair.

As a method for removing these allergens,
In addition to daily cleaning using a vacuum cleaner, rag, etc., a method of adhering and removing with an adhesive tape is generally used.
In addition to these methods, Japanese Patent Laid-Open No. 5-115237
In the gazette, for the purpose of capturing the body of ticks,
A method has been proposed in which a liquid adhesive is applied to a tatami surface or the like, heated and cured, and then the adhesive is peeled off. Since this method utilizes the fact that mites are attracted to heat, the heating operation is essential not only for hardening the adhesive but also for attracting mites.

[0004]

Although the daily cleaning method and the removal method using an adhesive tape are simple, it is possible to remove allergens that have entered minute gaps, recesses, grooves, etc., such as tatami mats, carpets, etc.
It is difficult to remove completely or to the extent that it does not induce allergies.

Further, since the method described in the above publication uses a liquid adhesive, the effect of trapping mites is excellent. However, since a heating means is required, the method of use becomes very complicated, and it may not be applicable depending on the place where the treatment is required. Furthermore, it is not effective against abiotic substances such as mite feces, carcasses, dust and dirt. In particular, it is unsuitable for general household use, which is highly necessary for the health of children and the like and requires a simpler usage method, and cannot be a sufficient solution to the problem.

[0006] Therefore, an object of the present invention is to provide an allergen removing agent which is easy to use, has hygienic and sufficient allergen removing ability, and an allergen removing method using the same.

[0007]

Means for Solving the Problems As a result of intensive studies to achieve the above object, the present inventors have found that when a liquid containing a room temperature curable adhesive is used, a minute and complicated gap or The present invention has been completed, paying attention to the fact that it can permeate all over the surface of an object to be processed having an uneven shape and can contact with the allergen present therein, and that heat treatment is unnecessary.

The present invention provides an allergen remover characterized by containing a room temperature curable adhesive. Further, the present invention provides a method for removing an allergen, which comprises coating the surface of an object to be treated with the allergen removing agent, leaving the film at room temperature to form a film, and then peeling the film. Is.

As the room temperature curable adhesive used in the allergen remover of the present invention, a room temperature curable silicone rubber adhesive can be mentioned. In the present invention, a two-component type is preferable, but a one-component type is also available. Can be used. As these room temperature curing type silicone rubber adhesives, trade name TSE3562-A (two-component type), trade name TSE3502 (two-component type), trade name TSE399 manufactured by Toshiba Silicone Co., Ltd.
(One-pack type) and the like.

In the allergen remover of the present invention, a curing agent, a filler or a solvent can be further added in addition to the room temperature curing type adhesive.

The curing agent is a component for promoting the formation of a film. As this curing agent, in the case of TSE3562-A manufactured by Toshiba Silicone Co., Ltd., TSE356
In the case of 2-C or F and the product name TSE3502, the product name CE601 can be mentioned. The mixing ratio of these curing agents is TSE356 under the trade name of TSE356 when a room temperature curable silicone rubber adhesive is used as the room temperature curable adhesive.
In the case of 2-C or F, 5 to 20% by weight based on the weight
In the case of the product name CE601, it is preferable that the amount is 0.5 to 2% by weight because the film formation rate and the film strength can be further increased, and the product name TSE3 is particularly preferable.
In the case of 562-C or F, 8 to 12% by weight, trade name CE6
In the case of 01, 0.8 to 1.2% by weight is preferable.

The filler is a component that enhances the physical properties of the formed film, and is a preferable component for adjusting the film strength in the present invention. Examples of the filler include fine particle titanium dioxide, fine particle anhydrous silica, kaolin, calcium carbonate, polyethylene fine particles, latex and gum arabic, and these may be used alone or in combination of two or more kinds. The mixing ratio of these is 0 with respect to the weight of the room temperature curable adhesive.
It is preferable that the content is -50% by weight in order to impart appropriate strength to the film and facilitate the peeling work, and especially 5 to 50% by weight.
20% by weight is preferred.

It is preferable to select these fillers appropriately according to the object to be treated. For example, if the object to be treated has a relatively small gap such as a floor, fine particle titanium dioxide, It is preferable to add 5 to 10% by weight of fine particle anhydrous silica, fine particle polyethylene, calcium carbonate and the like. If the object to be treated has relatively many fine gaps such as tatami, fine particle titanium dioxide, fine particle anhydrous It is preferable to add 5 to 20% by weight of silica, fine particle polyethylene, calcium carbonate and the like.

The solvent is a component for increasing the permeability of the allergen scavenger, but when a one-part type room temperature curable silicone rubber adhesive is used, not only the permeability but also the coating property is improved. It is preferable to add it in order to increase it.
The solvent is preferably harmless to the human body, and examples thereof include isopropyl alcohol and ethyl alcohol. The blending ratio of this solvent is preferably 0 to 10% by weight based on the weight of the room-temperature-curable adhesive in order to enhance the permeability, and particularly preferably 2 to 5% by weight.

The allergen-removing agent of the present invention may further contain an appropriate amount of agents such as a tick repellent, a tick attractant, and acaricide depending on the purpose of use. In addition, since the chemical compounded in the present invention is removed from the object to be treated together with the film peeled off at the time of use, it does not remain and the secondary contamination by the chemical agent does not occur.

Next, an allergen removing method using the allergen removing agent of the present invention will be described. First, the object to be processed, such as window frames such as tatami mats, floors, rugs, aluminum sashes, various furniture such as desks, surfaces such as walls, remote controllers for TVs and coolers, etc. Regardless, it is coated with an allergen remover. The coating method is not particularly limited, and known methods such as a brush coating method, a roller coating method, and a spatula coating method can be applied. The coating amount varies depending on the type of the object to be treated, but it is an amount that can cover the entire surface of the object to be treated, and if it is an amount that can secure a film thickness that does not impair the peeling workability of the film, It is not limited. When coated in this manner, the liquid allergen scavenger penetrates all the way into the minute gaps, recesses, grooves, etc. of the object to be treated and comes into contact with the allergens present therein.

Next, after coating the surface of such an object to be treated, it is left at room temperature to cure the allergen removing agent to form a film. This leaving time varies depending on the presence or absence of a curing agent, etc., but is usually about several tens of minutes to several hours. After forming the film in this manner, the film is peeled off. At this time, as described above, the allergen that has been in contact with the allergen removing agent is taken into the inside of the film or removed from the object to be treated while being attached to the surface of the film.
