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 offices have become OA and buildings have become more intelligent, urban structures have been changing, and wiring, cables, electricity, information equipment, packaging materials, and building structures have become rattled. The so-called bite injury causes serious accidents and enormous economic losses. Also in terms of hygiene,
It causes odor damage of urine, feces, and the like, and also causes damage of infectious diseases caused by mites, fleas, and bacteria.
Various methods have been developed and implemented to implement these proactive protection measures. Of these, an animal repellent composition containing an animal repellent is applied to the surface of an animal repellent object,
A method of preventing bite damage by kneading into an object to be repelled by animals has been put into practical use.

When an animal repellent composition in which an animal repellent is encapsulated in microcapsules is applied to the surface of an animal repellent object to form an animal repellent film or kneaded into the animal repellent object, the microcapsule is an animal repellent agent. The film or the surface of the animal repellent target is scattered, or some of the microcapsules are mechanically destroyed and the animal repellent is diffused throughout,
If human skin touches this, the released animal repellent or the animal repellent that breaks down the microcapsules may affect the skin.

In order to solve the above-mentioned problems, an animal repellent film formed by applying an animal repellent or a film containing no animal repellent is formed on the surface of an animal repellent object mixed with an animal repellent composition. In this case, an animal repellent composition and an animal repellent method have been proposed, which can sufficiently maintain stable stability of the animal repellent for a long period of time and prevent humans from directly contacting the animal repellent.

[0005]

The above method is suitable for existing wiring, electric cables, etc., but when painting at a facility site, the painting environment is poor and gloves, masks, goggles, etc. must be worn. , Complete painting is difficult. Therefore, it is desired to perform treatment with an animal repellent in advance in the manufacturing process of electric cables and the like, and further to maintain the animal repellent stable. However, the currently proposed paint containing animal repellent is not dried after coating.
Since it takes about 30 minutes or more, the animal repellent treatment cannot be performed without lowering the line speed in the manufacturing process of the electric wires and cables.

[0006]

As a result of earnest research for solving the above-mentioned problems, the present invention uses UV-curable resin to adhere to an electric wire without lowering the line speed in the electric wire cable manufacturing process. It is due to the finding that a coating film with good properties can be obtained,
An animal repellent material for which a UV-curable top coat is applied to the surface of an animal repellent material in which microcapsules of an animal repellent agent are kneaded to stably maintain the animal repellent agent, an animal repellent method, and a surface of an animal repellent object An animal repellent material and an animal repellent characterized by applying a UV-curable coating material containing microcapsules of an animal repellent to and drying it, and then applying a UV-curable top coating material on it to maintain the stability of the animal repellent. On the way.

Microcapsules are scattered and immobilized in the animal repellent material or animal repellent coating film thus formed. To bite the coating applied by animals such as rats,
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 with 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) when the former method is adopted and the animal repellent composition (coating type animal repellent composition) when the latter method is adopted are the compositions thereof. Will be slightly different.

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

The application type animal repellent composition of the present invention comprises 99 to 50 parts by weight of UV curable unsaturated resin (as solid content) and 1 to 50 parts by weight of microcapsules of animal repellent.

If the content ratio of the microcapsule of the animal repellant is less than 1 part by weight, the animal repellant effect is lowered, and if the film thickness becomes thin due to the variation in the film thickness when applied,
The amount per area may decrease, which is not preferable.

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, and economically. There's 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.

The capsaicins used in the present invention have the formula
