Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a repellent which repels birds and animals such as crows, cats, moles and rats. Further, the present invention relates to molded articles and materials using the repellent.

[0002]

BACKGROUND OF THE INVENTION Hitherto, it has been reported that birds such as pigeons, crows, sparrows, bulbuls, and ducks eat seeds planted in fields or eat seedlings after rice planting. In addition, cats and crows break the garbage bag at the garbage collection site, scavenge the garbage inside, scatter the garbage around, and the mouse bites the electric wire such as the ceiling, causing electric leakage, short circuit, etc. .

In order to solve such a problem, repellents have been devised which dislike birds and animals and do not approach them. The repellents are sprayed on objects such as fields and garbage bags as a spraying agent.
In JP-A No. 903 and JP-A-8-225406, a repellent effect is imparted by incorporating a salicylic lower ester such as methyl salicylate or ethyl salicylate as a repellent in a synthetic resin.

[0004]

SUMMARY OF THE INVENTION Conventional repellents for birds and animals,
Alternatively, since synthetic resins containing repellents and processed products thereof use low-molecular substances such as methyl salicylate as active ingredients, they volatilize within a few days, making it difficult to maintain the repellent effect. In addition, the repellent is released into the atmosphere, which may adversely affect the environment. In order to maintain the repellent effect for a longer time, it was necessary to increase the concentration of the active ingredient or to add another ingredient such as an adsorptive filler.

Accordingly, the present invention provides a bird and animal repellent which can be produced at a low cost, maintains a repellent effect for a long period of time and does not adversely affect the environment, or a material using the repellent and processing of garbage bags and the like.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below in detail.

The active ingredient of the repellent in the present invention is represented by the following general formula

Embedded image Is a molecule represented by Here, X is an arbitrary substituent and is not particularly limited. X need not be a low molecule, but may be a high molecule. The degree of polymerization of the polymer is preferably from 3 to 67.

In the prior art, the active ingredient of the repellent has a low molecular weight, so that there is a problem that the repellent volatilizes during use and loses the repellent effect. In the present invention, since a polymer is used as an active ingredient, it does not volatilize,
The repellency can be stably maintained over a long period of time. However, depending on the purpose of use, a low molecule may be used as an active ingredient.

The polymer having a repellent effect can be used as long as it contains (Chemical Formula 4) in its structure, and is not particularly limited. Examples thereof include polybutene, and a copolymer or mixture of polybutene and polyisobutylene. Has a large repellent effect and is suitably used. Most preferably, it is polybutene. Here, the polybutene of the present invention is different from crystalline polybutene-1 obtained by stereoregular polymerization of 1-butene, and has a relatively low molecular weight obtained from a butene isomer mixture. The copolymerization ratio or mixing ratio of polybutene and polyisobutylene is not particularly limited. However, in the case of copolymerization, it is preferable to contain 60 to 80% of polybutene, and in the case of mixing, it is preferable to contain 60 to 80% of polybutene. The molecular weight is preferably 300 to 4000 in the case of polybutene. In the case of a copolymer of polybutene and polyisobutylene, it is preferably from 500 to 5,000.
In the case of a mixture of polybutene and polyisobutylene, it is preferable that polybutene is 300 to 4000 and polyisobutylene is 500 to 6000, respectively. Polybutene is widely used as a raw material for synthetic rubber and as an additive for chewing gum, and is inexpensive. It is tasteless, odorless and harmless, and emits no harmful gas even when incinerated, so that it does not adversely affect the environment.

The above-mentioned active ingredients can be used alone or by being held in a suitable carrier. For example, it can be granulated and sown in a field, but can also be used after dissolving in a suitable solvent. For example, with polybutene,
It can be used as a repellent for a solution in which orthodichlorobenzene and xylol are mixed as a solvent.

By spraying such a liquid repellent on a target directly as a spraying agent with a sprayer or the like, repellency can be imparted to the target. The method of spraying and the object are not particularly limited.For example, when spraying with a hand sprayer on a field in which bean seeds are planted, when spraying with a sprayer from a plastic bag or the like in a garbage storage area, a pigeon
In order to prevent crows from forming nests or gathering, they can be sprayed on power lines or station platforms with a sprayer, or sprayed directly on trees. Orthodichlorobenzene, as the type of solvent when used as a spraying agent,
Xylol, chlorinated hydrocarbons, aromatic hydrocarbons, kerosene, turpentine, and the like are included, but are not limited thereto, and are appropriately selected depending on the purpose of use. The concentration of the active ingredient is determined by the kind of the active ingredient, the kind of the solvent and the like, and is not particularly limited, but is 10 to 20%.
Is preferred.

In addition to being used as a spraying agent, it can also be used as a variety of bird and animal repellent waxes, compressed resin oils, lubricating oils, paints and the like.

When a polymer is used as an active ingredient of the spraying agent, if the molecular weight is large, the viscosity of the solution may be so high that it may not be possible to use the solution. Therefore, the smaller the molecular weight, the more preferable it is, specifically, 300 to 1,000. For example, in the case of polybutene, the molecular weight is preferably 300 to 600.

When the following repellents are contained in the synthetic resin or the like instead of the spraying agent, those having a higher molecular weight can be used.
00 can be used.

In addition to using the repellent as a solution,
It can also be used as a bird and animal repellent material contained or attached to synthetic resin or paper. Hereinafter, such a case will be described in detail.

First, the case in which it is contained will be described. As the type of synthetic resin or paper material to be contained,
There is no particular limitation, and general materials that have been used conventionally can be applied. For example, in synthetic resins, low density polyethylene, high density polyethylene, linear low density polyethylene, polypropylene, polyester, polystyrene, nylon, polybutadiene, epoxy resin, urethane resin, polyvinyl chloride, polyvinylidene chloride, polyvinyl acetate, polymethyl methacrylate, An ethylene-vinyl acetate copolymer may be used, but is not limited thereto. As the paper material, either natural paper or synthetic paper can be used, and sheet materials, cardboard paper, Japanese paper, recycled paper, and the like can be used.
In addition, any other repellent can be used, and examples thereof include fillers such as asphalt, wood, and glass fiber, cloth, leather, and impregnating materials.

The method of incorporating the repellent may be any method as long as it can be contained in the object, and is not particularly limited. For example, there is a method in which polybutene is added to pellets of a synthetic resin such as polyethylene and kneaded, followed by molding, or a master batch containing polybutene together with various additives is produced, and the mixture is kneaded with a synthetic resin such as polyethylene and molded. Alternatively, paper, cloth, wood, or the like may be impregnated with the repellent. Further, not only the case where the repellent is directly contained, but also the case where the repellent is contained as a result of polymerization after impregnation of the monomer is included.

The amount contained in the synthetic resin varies depending on the active ingredient and the type of the object, and is not particularly limited, but is preferably from 10 to 60%. For example, when polybutene is used for the repellent to be contained and polyethylene is used for the object, an effective repellent effect can be obtained with a content of 10% or more, but if the content of polybutene is too large, the molded product becomes solid. Therefore, the content is preferably 10 to 40%.

Next, a case where a repellent effect is imparted by attaching a repellent to the surface of an object such as a synthetic resin or paper material will be described. The term “attachment” refers to a state in which a repellent is present on the surface of the target object, and the type of the target object, the method of adhesion, and the portion to be attached are not particularly limited.

The types of objects to which the repellent can be attached include those similar to those containing the repellent, and include various synthetic resins, paper, asphalt,
Examples include wood, cloth, and leather, but are not particularly limited.

As a method of attaching, a printing, coating and the like can be mentioned, and a structure made by laminating a film made of a repellent to an object may be used.

As a printing method, gravure printing, silk screen printing, roll coat printing and the like can be mentioned.

Coating methods include brush coating, spray coating, roll coating, electrostatic coating, curtain coating,
An immersion method or the like may be used, but is not limited thereto.

Further, after the repellent is attached to the object, the repellent may be contained by penetrating the inside.

Furthermore, instead of directly attaching the repellent, the repellent can be polymerized and polymerized after the attachment to form a coating film of the repellent.

Further, the portion to be attached can be attached to the entire surface of the object, or can be attached to a part of the surface of the object such as stripes and spots.

The synthetic resin or paper material containing the repellent or adhered to the surface as described above can be used as a bird and animal repellent material which itself has repellency. Further, it can be processed into various forms to obtain a molded product that is repellent to birds and beasts. Examples include, but are not limited to, bird and animal repellent caulking materials, electric wires, greenhouses, plastic buckets, garbage bags, bird repellent printed matter, and the like.

A bag or paper bag made of a synthetic resin film having bird-and-animal repellency can be obtained by making the bird-and-animal-repellent synthetic resin or paper material into a bag. As described above, the repellent may be contained in the material constituting the bag, or may be attached to the surface of the bag.

The method of manufacturing the bag in which the repellent is contained or adhered to the synthetic resin can be any conventional molding method that can be used, and is not particularly limited. For example, (1) Polyethylene is formed into a cylindrical film by inflation molding, cut into a predetermined length, and heat-sealed at the bottom to form a polyethylene bag, and then, on the surface thereof, polybutene or a copolymer of polybutene and polyisobutylene or A method of adhering the mixture by gravure printing, silk screen printing, roll coat printing, etc. (2) In molding a polyethylene bag, 10 to 60% by weight of polybutene or a copolymer or mixture of polybutene and polyisobutylene is added to a masterbatch. Then, it is mixed with polyethylene to form a cylindrical film by inflation molding, cut into a predetermined length, and heat-sealed at the bottom. (3) Polybutene, or a copolymer or mixture of polybutene and polyisobutylene, 10 to 60% by weight When, after mixing the polyethylene 40-90% by weight, and a cylindrical film by inflation molding, and a method of heat sealing the bottom portion by cutting and the like to length.

Similarly, in the method for producing a paper bag having repellency to birds and animals, a repellent may be attached to the surface of the bag by printing or the like, or the paper may be impregnated with the repellent.

When this repellent bag is used, for example, as a garbage bag, it does not attract cats or crows even when left outside, so that the garbage is not broken and broken. Moreover, since the polymer is used as the repellent component, the repellent effect can be maintained for a long time without volatilization. Polybutene does not generate harmful gas when incinerated, and does not adversely affect the environment.
