Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a repellent material for wild animals, and more specifically, it prevents the animal from approaching by causing the molded porous body to carry the odor repelled by the wild animal and continuously generating the odor. It is used to prevent the damage. As the molded porous body, natural diatomaceous earth is used after being molded and fired, so it is reduced to soil components by natural collapse after the repellency function is lost.

[0002]

[Prior art]

 Wild animals cause various damages in the vicinity of human dwellings. For example, there is pollution from manure in dogs, cats, birds, etc., and feeding damage to growing plants. Various measures have been taken to prevent this. Recently, synthetic polymer foam is impregnated with an odorless liquid that is repelled by animals and placed at a required location, or water is added to polybin to make animals vigilant by the reflection of light. .

The polymer foam is easily blown off by the wind, has a problem that the treatment after the odor is reduced and the effect is ineffective, and the polybin is ineffective and requires manual labor for its placement and removal. Moreover, placing these objects often interferes with the functions of the neighborhood and impairs aesthetics. For example, when these measures are applied to the sandbox, it becomes an obstacle to children's play, and it takes time and effort to remove the sandbox after it loses its aesthetic effect.

In addition, the repellent applied to the fields to prevent damage to agricultural products should not adversely affect the agricultural work, is easy to use and is sustainable, and when it becomes unnecessary. Is preferably one that naturally disappears. In this respect, the conventional wildlife repellent materials are difficult to use, and the carrier carrying the drug does not spontaneously disappear after use, which is often an obstacle in terms of aesthetics and agricultural work.

[0005]

[Problems to be Solved by the Invention] The present invention uses a porous body having a sufficient internal surface area to carry a drug having a repellent effect on wild animals, and the porous body has an appropriate collapse property. By selecting a substance that has the property of becoming harmless after being collapsed and returned to the soil, a product that is easy to use and has a repellent effect on wild animals that does not cause pollution after use is obtained. , Is to develop and provide.

[0006]

[Means for Solving the Problems]

Natural diatomaceous earth has fine open pores, has an internal surface area of about 10,000 cm ² per gram, and has the property of absorbing liquid at nearly 100% of its own weight. However, as it is, it tends to disintegrate into a powder when dried, and when it absorbs a large amount of liquid, it becomes a mud, which makes it unsuitable for use as a carrier of a drug having a repellent effect on wild animals. Is.

However, when water is added to diatomaceous earth to form a clay, and the mixture is molded and then baked, the inside of the molded body is partially sintered, and the internal surface area of the diatomaceous earth is not substantially impaired, and it can withstand a certain level of pedaling pressure. A fired body having the strength of is obtained.

When this fired body is impregnated with a compound having an animal repellent action, the compound is partially adsorbed on the inner surface of the fired body or is carried by the capillary phenomenon, so that the dry weight of the molded product is close to 100%. Even if it is supported up to this point, the surface will remain dry and easy to handle. Therefore, if this is used as an animal repellent material, the problems of the repellent materials up to now can be solved. Furthermore, after the effect disappeared, it gradually disintegrated and returned to the soil, but even when it became small particles, it showed the aggregate effect of the soil because of the porous structure, and on the contrary, it also had the soil improving effect. Based on this, the present invention was reached.

That is, a cylindrical fired body having a diameter of 0.5 to 10 mm and a length of 1.5 to 4 times the diameter obtained by firing diatomaceous earth at 1000 ° to 1400 ° C. has a repellent effect on wild animals. It is a wildlife repellent material obtained by impregnating 5% by weight or more of a volatile compound that gives Here, as the volatile compound that gives a repellent effect to wild animals, naturally occurring oils and fats such as peppermint oil and orendi peel oil, camphor white oil, and synthetic compounds such as phenol, acrylic monomer, cellosolves, and acetophenone are preferable.

Here, the columnar fired body is not limited to a strictly geometrical columnar shape, but has a wide range of columnar shapes in which some of the corners are missing or the shape of the cylinder is slightly distorted. Is also included in the present invention because it also exhibits a repellent effect on wild animals. The present invention will be described in detail below.

Natural diatomaceous earth is kneaded with water, extruded through pores, cut to a predetermined length, and dried at 1000 ° to 1400 ° C. so that continuous pores remain. In the cylindrical fired body made here, since the diatomaceous earth melting caused by the firing is partial, the structure with continuous pores of diatomaceous earth is retained and it has a certain degree of strength, but it is left to stand naturally. If so, it has the property of exhibiting a suitable degree of collapse.

Since the wildlife repellent often mixes with sand or soil when sprayed, the size of the fired body needs to be cylindrical with a diameter of 0.5 to 10 mm. This is because if the diameter is 0.5 mm or less, the repellent action of wild animals is poorly sustained, and if the diameter is 10 mm or more, the unevenness of the soil after spraying becomes large, which often causes obstacles to walking. Also, the ratio of the length of the cylindrical shape to the diameter must be within the range of 1.5 to 4 times. If it is less than 1.5 times, a large amount of powder generated at the time of molding mixes in the fired body, so the sustained release rate of the component with repellent effect will vary, and if the ratio with the diameter is more than 4 times, it will be difficult to spray, and after spraying This is because it is easily noticeable and may cause obstacles when walking. From these viewpoints, the ratio of the diameter and the length of the cylindrical shape is more preferably in the range of 2 to 4 times.

It is possible to make the shape of the fired body spherical, but in that case, it is necessary to first form a shape in which the ratio of the length to the diameter is close to 1 and round it with a tumbler or the like. . In this case, as described above, the amount of the by-product of the powder increases, so that the sustained release property of the component having the repellent action is disturbed and the production efficiency also decreases.

In order to produce the wild animal repellent material of the present invention, it is necessary to impregnate the columnar fired body thus obtained with 5% by weight or more of a volatile compound having a repellent effect on wild animals. The components of the compound are not particularly limited, and a wide range of volatile compounds that have a repellent effect on wild animals can be used. Among these compounds, natural oils and fats include mint oil and orange peel oil, camphor white oil and other natural compounds. Those collected from are preferable for human safety and environmental protection. In addition, pine oil and perilla extract oil are also preferable, and these oils and fats may be a single component or a mixture of two or more kinds.

Further, as the synthetic compound, phenol, acrylic monomer, cellosolves, acetophenone and the like are preferable. Other materials such as xylene, light oil, and styrene monomer can also be used. These synthetic compounds can be used as a single component or as a mixture of two or more kinds, or may be mixed with naturally occurring fats and oils. Further, it is possible to synergistically enhance the repellent effect by adding an organic acid contained in a crop or the like, such as malic acid, citric acid or glutaric acid.

The impregnated amount of the volatile compound having a repellent effect on wild animals in the fired body must be 5% by weight or more. This is because if it is less than 5% by weight, the repellent action and its durability become poor. The upper limit of the impregnated amount is not particularly limited, and an appropriate impregnated amount can be used depending on the properties of the compound. However, when the impregnated amount is 100% or more of the dry weight of the fired product, the surface feels wet and the sustained release is achieved. It tends to be disturbed.

[Embodiment of the invention]

When a porous diatomaceous earth fired body is impregnated with these wild animal repellent compounds, the compound is retained on the inner surface of the porous body by adsorption or capillary action, so that volatility is suppressed and sustained release is achieved. Will be displayed. Therefore, the volatility of the repellent material can be reduced to the extent necessary and sufficient for repelling wild animals, and the durability of the repellent effect can be enhanced. In order to impregnate the fired body with the liquid repellent compound, it is possible to easily impregnate the fired body uniformly with a method such as spraying or a tumbler.

The thus obtained wildlife repellent material can be used by an appropriate method such as by spraying it at a desired place or by partially arranging it like heaping salt. The odor of the repellent is gradually dissipated over a long period of time from the location where the burned material has been sprayed or accumulated, during which time wild animals can stay away and exert an exterminating effect. It is also possible to put the molded body in a net bag and hang it, and the method of use is easy and its effect is great.

Since the main component of diatomaceous earth is silica, and the degree of calcination of the calcined body is low, after the repellent compound has volatilized, it is gradually decomposed and returned to the soil even if it is left as it is. There is no risk of causing pollution or adversely affecting the ecosystem. In addition, since the small particles that collapsed at that time also have a porous structure, they have the function of agglomerating the soil to enhance its function, and also have the function of retaining fertilizer to sustain its effect.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to examples.

Example 1 A calcinated body having an average diameter of 2 mm and an average length of 5 mm obtained by molding diatomaceous earth at 1200 ° C. was impregnated with camphor white oil in an amount of 30% of its dry weight to make it wild. An animal repellent material was prepared. A perspective view of the obtained animal repellent material is shown in FIG.

This repellent material for wild animals was sprayed under the eaves at a rate of about 100 g / m ² . As a result, the stray cats did not approach for almost one month. The sprayed material had an appearance that was in harmony with the soil under the eaves, and became a constituent of soil naturally after the odor disappeared. Further, since the fired body is porous, even if it is impregnated with camphor white oil as much as 30% of its weight, the texture remains dry, and it is easy to spray and the hands are not sticky.

The volatilization rates of camphor white oil impregnated in the calcined diatomaceous earth and camphor white oil alone were measured in a room at 12 ° C. in the same state for comparison, and the results are shown in Table 1. From these results, it was found that the volatilization rate of camphor white oil impregnated in the calcined diatomaceous earth was much lower than that of camphor white oil alone. This indicates that the wildlife repellent material of the present invention has a release effect, and it can be seen that the duration of the effective repellent effect is prolonged.

[0024]

[Table 1]

Example 2 A fired body having an average diameter of 5 mm and an average length of 12 mm obtained by molding diatomaceous earth after firing at 1400 ° C. was impregnated with 40% of the dry weight of peppermint oil. . (a) This fired product was sprayed on rice ridges at a rate of 50 g / m ² before the ears grew. It was a year of heavy boar damage, but boars did not approach this field. (b) This fired product was sprayed at a rate of 30 g / m ^{2 on} the ceiling above the kitchen in the dining room. The rat's appearance and noise disappeared, and the effect was fully observed for one month.

50 g of each of these was placed in a small net bag and placed in the second eaves of the factory at a rate of 50 g / m ² . The pigeons did not approach and the feces were harmed, and the effect was fully observed for 3 weeks.

The volatilization rates of the mint white oil impregnated in the calcined diatomaceous earth and the mint white oil alone for comparison were measured in a room at 12 ° C., and the results are shown in Table 2. From these results, it was found that the volatilization rate of the peppermint white oil impregnated in the calcined diatomaceous earth was much lower than that of the peppermint white oil alone. This shows the sustained release effect of the wildlife repellent material of the present invention, and it can be seen that the duration of the effective repellent effect is prolonged.

[0027]

[Table 2]

Example 3 A calcinated body having an average diameter of 1 mm and an average length of 3 mm obtained by molding diatomaceous earth at 1200 ° C. was impregnated with 25% of its dry weight of orange peel oil to be wild. An animal repellent material was prepared. A perspective view of the obtained animal repellent material is shown in FIG. As shown in the figure, the corners of the cylinder are slightly missing, or the fired body in which the shape of the cylinder is distorted is included.

This animal repellent material was applied to children's sandbox at a rate of 100 g / m ² . The stray dogs did not dig up and touched the skin of the child, which was not harmful to hygiene, and its repellent effect was observed for at least 10 days. This spray does not hinder the play in the sandbox, and it can be seen by careful observation that it has been sprayed, and it does not spoil the beauty.

A fired body obtained by molding diatomaceous earth and firing at 1000 ° C. and having an average diameter of 1 mm and an average length of 2.5 mm was impregnated with butyl cellosolve at 25% of its dry weight. This impregnated baked product was sprayed at a rate of 100 g / m ² on the sand sprayed garden by the entrance. There was no excavation of dogs and cats, and the effect was fully observed for one month. Even if the impregnating agent is replaced with phenol, solfit, light oil, etc., the same effect can be obtained, and the aesthetic appearance is not deteriorated. In addition, no change was observed in the trees nearby.

Comparative Example 1 Pumice stone having a relatively large number of pores was crushed and used as a carrier for a wild animal repellent material. The yield was low in order to arrange the fine particles, and impregnating 20% of the dry weight of camphor oil made the surface of the pumice stone sticky, making it difficult to spray. Also, even after spraying, fine particles are easily formed by treading, which is not good in appearance.

Comparative Example 2 Camphor oil was impregnated with foamed perlite as a carrier. Only about 10% of the dry weight could be impregnated, and the surface of perlite became sticky and wet. In addition, after spraying, it quickly flows out due to rain or wind, and there is little repellent effect, and the appearance is not very good.

[0033]

[Effect of the invention]

 The cylindrical diatomaceous earth fired body impregnated with the repellent compound for wild animals according to the present invention can be produced at low cost and is easy to disperse. Also, by selecting the particle size, the aesthetics of the spray surface will not be impaired. When natural products are used as repellent compounds, there are no toxicity issues. Also, after the repellent effect is exhausted, the repellent material gradually disintegrates and assimilates with the soil, and is superior in terms of usage and ecology compared to conventional repellent materials.
