Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an animal repellent material and an animal repellent method which are compatible with animal repellency against vertebrates and mammals and human safety.

[0002]

2. Description of the Related Art In recent years, as the office structure has changed to OA and the building has become more intelligent, there have been ratches in wiring, cables, electricity, information equipment, packaging materials, and building structures. The so-called bite injury causes serious accidents and enormous economic losses. Also, in terms of hygiene, odors such as urine, feces, etc., and further, these mediate, mites,
It leads to the infectious disease caused by fleas and bacteria. Various methods have been developed and implemented in order to carry out these preliminary protective measures. Among them, an animal repellent composition containing an animal repellent is applied to the surface of an animal repellent target. A method of preventing bite damage by kneading into the object to be repelled by animals has been put into practical use.

[0003]

The animal repellents used for such conventional materials have their respective characteristics such as antibiotics and highly stimulative substances, and their effects and safety are In order to enhance the composition, an animal repellent composition in which an animal repellent is encapsulated in microcapsules has been proposed.

However, when an animal repellent composition in which such an animal repellent is encapsulated in microcapsules is applied to the surface of an animal repellent object to form an animal repellent film or when kneaded into the animal repellent object, Capsules are scattered on the surface of the animal repellent coating or the object to be repelled, or some microcapsules are mechanically broken and the animal repellent is diffused throughout, and this touches human skin. There is a risk that the released animal repellent or the animal repellent that breaks out of the microcapsules and leaks may affect the skin.

[0005]

Means for Solving the Problems As a result of earnest research for solving the above problems, the present inventor has found that an animal repellent film formed by applying an animal repellent composition or an object to be repelled by mixing the animal repellent composition. When a film containing no animal repellent is further formed on the surface of the object, stable maintenance of the animal repellent can be sufficiently performed for a long period of time, and further, it is possible to prevent a person from directly contacting the animal repellent. It has been found that the conventional drawbacks can be solved, and the present invention has been completed based on this finding.

The present invention is characterized in that an animal repellent composition is mixed with an object to be repelled or applied to the surface thereof, and then the top coating composition is applied to the surface thereof. Material and method thereof.

The animal repellant composition used in the present invention is a microcapsule of an animal repellant, or a mixture of the microcapsule and a resin, and in use thereof, it is mixed with an animal repellant object or the surface thereof. It is applied to and dried to form an animal repellent film.

Microcapsules are scattered and immobilized in the animal repellent material or animal repellent coating film thus formed. To bite the coating that animals such as rats are applying,
At the time of placing a tooth, the capsule breaks, the animal repellent is released, and the bite is stopped, that is, the repellent effect is exerted.

In the present invention, the animal repellent composition is mixed and kneaded into the animal repellent object, or is applied to the surface of the animal repellent object.

Therefore, the animal repellent composition (kneading type animal repellent composition) in the case of adopting the former method and the animal repellent composition (coating type animal repellent composition) in the case of adopting the latter method are The composition will be slightly different.

That is, the kneading-type animal repellent composition comprises
Since it is simply kneaded into an animal repellent target, its main component is only the microcapsules of the animal repellent as described below, but in the smearable animal repellent composition, this is applied to the surface of the animal repellent target. In order to form an animal repellent film by applying the resin component, a resin component that functions as a binder component is required in addition to the microcapsule of the animal repellent.

The smearable animal repellent composition of the present invention comprises 99 to 50 parts by weight of a resin such as a solvent-based resin in the form of an organic solvent solution or dispersion, or an aqueous emulsion or a water-based resin in the form of an aqueous solution. The microcapsules of the animal repellent (as a solid content) are contained at a ratio of 1 to 50 parts by weight.

When the content ratio of the microcapsule of the animal repellent is less than 1 part by weight, the animal repellent effect is lowered, and when the film thickness becomes thin due to the variation in the film thickness when applied,
The amount per area may be reduced.

On the other hand, the greater the amount of the animal repellent microcapsules, the greater the animal repellent effect. However, when the amount exceeds 50 parts by weight, the strength of the coating film and the adhesive force to the animal repellent object are remarkably reduced, which is economically economical. Also has a problem.

The animal repellent used in the present invention is not limited as long as it has an animal repellent effect, but capsaicins and / or cycloheximide are particularly preferable.
