Description

[Technical Field]

[0001] The present invention relates to an animal repellent resin composition, and more particularly to a repellent resin composition targeted at mammals. [Background technology]

[0002] In addition to the deer, wild boars, and bears that have inhabited the area since ancient times, non-native species of animals are becoming increasingly feral, and in recent years there have been increasing cases of them invading areas of human activity and causing harm. For example, there has been an increasing trend in so-called roadkill, where wild deer enter roads or railway tracks and collide with vehicles. Damage to crops and damage to planted young trees has also become serious.

[0003] Various repellents have been used to prevent wildlife from entering specific areas. For example, natural repellents that stimulate animals' senses of taste and smell and are environmentally friendly include capsaicin, wood tar, herbs, garlic, the hair, blood, and excrement of predators such as wolves and bears, and vinegar (Patent Documents 1 and 2).

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-210791 [Patent Document 2] Patent No. 6224691 Summary of the Invention [Problem to be solved by the invention]

[0005] However, many conventional animal repellents are liquid, which makes them difficult to handle and place in a designated location. For example, liquid repellents can be converted into easy-to-handle articles by impregnating or retaining them in a solid substrate. However, under outdoor exposure conditions, the repellent tends to run off or evaporate quickly, making it difficult to extend the duration of repellent performance. Furthermore, there is also the problem that the repellent effect decreases over time because animals become accustomed to the repellent.

[0006] The present invention solves the above-mentioned problems, and its purpose is to provide an animal repellent resin composition that can be used to create an animal repellent article that has a low environmental impact, is easy to handle, has a long effective life, and is difficult for target animals to become accustomed to.

[0016] According to the present invention, an animal repellent resin composition is provided which can realize an animal repellent article that has a low environmental impact, is easy to handle, has a long useful life, and is difficult for target animals to become accustomed to. DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, one embodiment of the present invention will be described in detail, but the scope of the present invention is not limited to the embodiment described here, and various modifications can be made without departing from the spirit of the present invention. Furthermore, when multiple upper and lower limit values ​​are specified for a specific parameter, any upper and lower limit values ​​can be combined to form a suitable numerical range.

[0018] <Animal repellent resin composition> The animal repellent resin composition of the present invention comprises (A) a thermoplastic resin, and (B) sustained-release inorganic particles and (C) an animal repellent dispersed in the thermoplastic resin.

[0019] (A) Thermoplastic resin The thermoplastic resin is a polymeric compound that is solid at room temperature and softens upon heating to such an extent that the sustained-release inorganic particles and the animal repellent can be dispersed therein. By using the thermoplastic resin, the liquid animal repellent can be converted into a solid at room temperature and can be formed into a desired shape. As a result, the animal repellent is easier to handle.

[0020] The thermoplasticity of a thermoplastic resin is expressed by the softening point of the resin. To suppress transpiration loss during the process of kneading the animal repellent, the thermoplastic resin is preferably a resin that softens at a relatively low temperature. The thermoplastic resin preferably has a softening point of 50 to 120°C. If the softening point of the thermoplastic resin is less than 50°C, the hardness at room temperature decreases, accelerating the release of the animal repellent, which tends to shorten the effective life of the animal repellent article. On the other hand, if the softening point exceeds 120°C, transpiration loss of the animal repellent occurs when kneading it into the thermoplastic resin, or the hardness at room temperature increases, suppressing the release of the animal repellent, which tends to reduce the repellent effect of the animal repellent article.

[0021] The thermoplastic resin may be used alone or in combination of two or more. In this case, the softening point of the thermoplastic resin that forms the matrix of the animal repellent resin composition is used.

[0022] Examples of thermoplastic resins include polyethylene, polypropylene, ethylene-vinyl acetate copolymer, styrene-based thermoplastic elastomers, and mixtures thereof (specifically, mixtures of polyethylene and ethylene-vinyl acetate copolymer, and mixtures of polypropylene and ethylene-vinyl acetate copolymer). Among these, preferred thermoplastic resins are those described in Japanese Patent No. 3963941, which form a liquid-in-solid polymer emulsion by incorporating a liquid compound (C) therein. The entire disclosure of this publication is incorporated herein by reference.

[0023] The thermoplastic resin is a mixed resin containing a matrix-forming thermoplastic polymer (A) and a domain-forming block copolymer (B). (B) is composed of a block (B1) that is highly compatible with (A) but poorly compatible with a liquid compound (C), and a block (B2) that is highly compatible with (C) but poorly compatible with (A), and is phase-separated from (A).

[0024] In such a thermoplastic resin, the block copolymer (B) acts as a surfactant to form an interface between the thermoplastic polymer (A) and the liquid compound (C), resulting in the formation of a liquid-in-solid polymer emulsion in which the liquid compound (C) is present at a high concentration inside the thermoplastic polymer (A).

[0025] One embodiment of the thermoplastic resin is at least one styrene-based thermoplastic elastomer selected from poly(ethylene / propylene)-polystyrene block copolymers (SEP), polystyrene-poly(ethylene / butylene) block copolymers (SEB), polystyrene-poly(ethylene / propylene)-polystyrene block copolymers (SEPS), polystyrene-poly(ethylene / butylene)-polystyrene block copolymers (SEBS), and polystyrene-poly(ethylene-ethylene / propylene)-polystyrene block copolymers (SEEPS), in which the thermoplastic polymer (A) is a polyolefin-based polymer and the block copolymer (B) has, as block (B1), a polyolefin block that is highly compatible with the polyolefin-based polymer [thermoplastic polymer (A)] and, as block (B2), a polystyrene block that is highly compatible with the liquid compound (C).

[0026] Another form of the thermoplastic resin is at least one selected from poly(ethylene / propylene)-polystyrene block copolymers (SEP), polystyrene-poly(ethylene / butylene) block copolymers (SEB), polystyrene-poly(ethylene / propylene)-polystyrene block copolymers (SEPS), polystyrene-poly(ethylene / butylene)-polystyrene block copolymers (SEBS), and polystyrene-poly(ethylene-ethylene / propylene)-polystyrene block copolymers (SEEPS), in which the thermoplastic polymer (A) is a polystyrene-based polymer and the block copolymer (B) has, as block (B1), a polystyrene block that is highly compatible with the polystyrene-based polymer [thermoplastic polymer (A)], and as block (B2) a polyolefin block that is highly compatible with the liquid compound (C).

[0027] In addition, from the viewpoint of environmental consideration, non-petroleum-derived bioplastics and biodegradable resins can also be used.

[0028] (B) Sustained-release inorganic particles The sustained-release inorganic particles are porous inorganic particles having a porous structure with numerous pores on the high-order surface. The porous inorganic particles may be in powder form. The pores of the porous inorganic particles accommodate and retain the animal repellent, preventing it from prematurely leaking or evaporating from the matrix resin. As a result, the animal repellent resin molded article can exhibit a sustained-release effect, releasing the animal repellent over a long period of time.

[0029] The type of sustained-release inorganic particles is not particularly limited, and environmentally friendly and highly safe particles may be selected from those that have been used for similar purposes. Specific examples of preferred sustained-release inorganic particles are shown below.

[0030] (fly ash) Fly ash here refers to ash obtained by burning charcoal or silica-alumina composite particles. Fly ash may also be finely powdered coal ash produced in thermal power plants that burn coal using a pulverized coal combustion method.

[0031] (activated clay) Activated clay is made by treating so-called bentonite, which is mainly composed of montmorillonite, or acid clay with sulfuric acid to enhance its activity. Activated clay is mainly composed of alumina, MgO, iron oxide, and calcium oxide.

[0032] (inorganic pigments) The inorganic pigment may be any of those commonly used for coloring resin compounds, such as cuprous oxide, titanium oxide, and red iron oxide.

[0033] (silica) The term "silica" as used herein refers to a substance that has a porous structure and is mainly composed of silicon oxide. As the porous silica, either vapor-phase silica or wet-process silica may be used.

[0034] (Char) Char is a black powder containing 80% or more by weight of carbon components, which is a by-product of the biomass power generation process.

[0035] From the viewpoint of effectively utilizing industrial waste and reducing adverse effects on the environment, the preferred controlled-release inorganic particles are char.

[0036] The sustained-release inorganic particles may be used alone or in combination of two or more types.

[0037] The sustained-release inorganic particles have a primary particle size of 0.01 to 50 μm and an average particle size D 50 If the average particle size of the sustained-release inorganic particles is less than 0.01 μm, thermal aggregation is likely to occur during the kneading and molding processes, resulting in a lack of uniform dispersion, while if it exceeds 50 μm, the flowability is poor and the strength of the molded product tends to decrease. The average particle size of the sustained-release inorganic particles is more preferably 0.1 to 10 μm, and even more preferably 0.5 to 2 μm.

[0038] The content of the sustained-release inorganic particles is preferably 0.5 to 30 wt% based on the total animal repellent resin composition. If the content of the sustained-release inorganic particles is less than 0.5 wt%, the sustained-release effect of the animal repellent resin molding will be reduced, and if it exceeds 30 wt%, the compound will have poor fluidity when melted, which will reduce the efficiency of melt molding and reduce the strength of the animal repellent molding. The content of the sustained-release inorganic particles is more preferably 1.0 to 20 wt%, and even more preferably 5.0 to 10 wt%.

[0039] (C) Animal repellents An animal repellent is a repellent for wild animals and harmful animals that, when volatilized, emits a foul, irritating, or unpleasant odor that stimulates the sense of smell of wild animals and harmful animals, causing them to repel from the installation location. The type of animal repellent is not particularly limited, and an environmentally friendly and highly safe one may be selected from those that have traditionally been used for similar purposes. Specific examples of preferred animal repellents are shown below.

[0040] (wood tar) Wood tar is a liquefied product of the smoke produced when wood is roasted. The smell of wood tar makes animals instinctively aware of the danger of forest fires, and they tend to stay away.

[0041] (pyrazine derivatives) These compounds are found in wolf urine, and their odor scares off pests and other animals, preventing them from approaching. Specific examples include 2,6-dimethylpyrazine, 3-ethyl-2,5-dimethylpyrazine, and 2,3,5-trimethylpyrazine.

[0042] (Thiazole derivatives) An example of a substance that induces innate fear emotion is 2,4,5-trimethylthiazole, a compound described in WO2011 / 096575 as an active ingredient in an animal repellent.

[0043] (garlic oil) It contains low molecular weight sulfur-containing substances such as sulfides and mercaptans, which volatilize and produce a foul odor.

[0044] (Capsaicin-containing oil) The capsaicin component sublimates and produces a pungent odor.

[0045] The animal repellent is preferably liquid at room temperature, from the viewpoint of being easily retained in the sustained-release inorganic particles and easily evaporating from the retained state. One type of animal repellent may be used, or two or more types may be used in combination.

[0046] The content of the animal repellent is preferably 1.0 to 20% by weight based on the total weight of the animal repellent resin composition. If the content of the animal repellent is less than 1.0% by weight, the repellent effect of the animal repellent resin molded article will decrease, and if it exceeds 20% by weight, there is a concern that the repellent will bleed out onto the surface of the molded article, making it difficult to handle. The content of the animal repellent is more preferably 2.0 to 15% by weight, and even more preferably 5.0 to 10% by weight.

[0047] The animal repellent resin composition of the present invention can be produced by blending sustained-release inorganic particles and an animal repellent with a thermoplastic resin using a conventional heating and kneading device, liquefying the thermoplastic resin, kneading the blend until it is homogeneous, and then cooling. In this case, the method of kneading a liquid repellent, as described in Japanese Patent Nos. 3,963,941 and 4,576,479, may also be used.

[0048] For example, using a typical twin-screw resin kneading extruder, thermoplastic resin is first fed from a resin pellet feed hopper and sent through a screw while being heated above the resin's melting point. Sustained-release inorganic particles are then added from a downstream powder feed hopper and kneaded into the molten thermoplastic resin. An animal repellent is added to the kneaded mixture using a plunger pump or similar, and further kneaded to ensure uniform dispersion. The kneaded mixture is then extruded through a die head, the strands are passed through water to cool, and then cut with a cutter to form pellets.

[0049] <Animal repellent resin molded body, animal repellent resin molded body article> The resulting pellets are kneaded using an extruder and then injected into a mold attached to the tip of the extruder for injection molding, thereby producing an animal repellent resin molded article having a desired shape. Instead of molding into pellets, the molten animal repellent resin composition may be extruded directly into a mold for injection molding. Shapes of animal repellent resin molded articles produced by injection molding include, for example, breathable mesh plates and lattice plates. The animal repellent resin molded article may be, for example, a three-dimensional mesh sheet molded from pellets or a molten animal repellent resin molded article using a random extrusion three-dimensional mesh manufacturing machine, which draws threads from a molten resin at high speed and crosses the threads to form a three-dimensional mesh.

[0050] These animal repellent resin moldings can be used alone or in combination to form animal repellent resin molding articles. For example, animal repellent resin compositions such as mesh plates, lattice plates, and three-dimensional mesh sheets containing different types of animal repellents can be layered to form an animal repellent resin molding article containing multiple types of animal repellents. In this case, when an animal steps on the animal repellent resin molding article, the multiple types of repellents contained in the layers themselves and in the spaces between the layers are released into the atmosphere, thereby providing an even more effective repellent effect.

[0051] By combining two or more types of animal repellents, the composition of the evaporated mixed repellent can be changed, and even if wild animals become accustomed to a particular combination of repellents, it can be easily changed to a different combination, thereby preventing acclimatization.

[0052] Furthermore, by combining two or more animal repellents, the evaporation rates of each repellent differ, and the quality of the odor emitted from the animal repellent molded article changes over time. As a result, even wild animals that are becoming accustomed to the initial odor will perceive the change in odor quality as a new stimulus, thereby preventing acclimatization.

[0053] The animal repellent molded article of the present invention has an odor such as a foul odor, an irritating odor, or an unpleasant odor that acts on the sense of smell and repels animals with the odor. The animal repellent molded article of the present invention is applicable to animals that dislike and are repelled by the odor of the animal repellent. Specific examples of such animals include mammals such as monkeys, bears, deer, wild boars, raccoon dogs, foxes, raccoons, palm civets, mice and rats, rabbits, and squirrels. Among these, the mammals against which the animal repellent molded article of the present invention is considered effective are deer, wild boars, raccoon dogs, foxes, raccoons, and palm civets. [Example]

[0054] The present embodiment will be described in detail below with reference to examples, but the present invention is not limited to the following examples.

[0055] The following materials were prepared:

[0056] [Table 1]

[0057] [Table 2]

[0058] [Table 3]

[0064] Compound (5): Capsaicin-containing oil G + activated clay Q Pellets containing capsaicin-containing oil and activated clay were obtained in the same manner as in Compound (4), except that activated clay was used instead of char.

[0065] Compound (6): 2,6-dimethylpyrazine B + cuprous oxide R 20 parts of 2,6-dimethylpyrazine, which had been heated to 40°C or higher to melt, was blended with 80 parts of EVA resin at an ambient temperature of 40°C, and stirred to allow swelling and absorption, yielding pellets. The pellets were mixed in a weight ratio of pellets / PE / cuprous oxide = 44.5 / 44.5 / 1.0, kneaded in a twin-screw kneader, cooled, and pelletized to obtain pellets containing 2,6-dimethylpyrazine and cuprous oxide.

[0066] Compound (7): 3-ethyl-2,5-dimethylpyrazine C + cuprous oxide R 20 parts of 3-ethyl-2,5-dimethylpyrazine was blended with 80 parts of EVA resin and stirred to allow swelling and absorption, yielding pellets.

[0069] <Method for evaluating deer repellency> Fence installation A wire mesh fence measuring 5.5 m deep, 5.2 m wide, and 1.5 m high was installed on the grounds of a deer ranch. Two entrances, each 0.7 m wide and 1.5 m high, were installed on one side of the 5.5 m deep and 1.5 m high (hereinafter referred to as the "entrance side"). A feeding table was installed on the side of the fence opposite the entrances, 5.5 m deep and 1.5 m high (hereinafter referred to as the "feeding side").

[0070] - Form of installing a repellent structure (Case 1) The repellent structure is attached to the entrance surface and both side surfaces of the fence section, excluding the feeding surface. (Case 2) The repellent structure is placed on the ground in front of the two entrances, with the same width as the entrance surface.

[0071] Repellency test procedure Deer were attracted to the fence with bait, then placed in a feeding station inside the fence. The first bait was then removed, and the deer's behavior was observed. The number of deer that entered the fence and ate from the feeding station was recorded.

[0072] This procedure was performed first on the test day using a fence without a repellent structure, and then again after the fence had been equipped with a repellent structure.

[0073] Determining repellency rate The repellency rate was determined according to the following formula:

[0074] Repellent rate R(%)={(NM) / M}×100 In the formula, N is the number of deer that entered the fence to eat bait when the repellent structure was not installed, and M is the number of deer that entered the fence to eat bait when the repellent structure was installed.

[0075] <Method for evaluating changes in odor over time and odor longevity> Every 30 days, the inventors performed a sensory evaluation of the quality and intensity of the odor perceived by standing 5 m from the repellent structure installed on the fence, recorded the results, and determined whether the quality of the odor changed over time. They also determined the period of installation at which the odor itself could no longer be perceived.

[0076] Example 1 Wood tar A, garlic oil F, capsaicin-containing oil G, silica S, char T, lattice board Using a general-purpose injection molding machine and mold, compound (1) was molded into a grid plate measuring 30 cm in length, 30 cm in width, and 0.5 cm in thickness. Similarly, compounds (2) and (4) were mixed in a 50 / 50 weight ratio and molded into a grid plate. The resulting molded pieces were stacked and joined to form a 30 cm wide strip. This was installed on a fence in the form of (Case 1). The deer repellent performance, odor change over time, and odor longevity were then evaluated.

[0077] <Example 2> Wood tar A, 2,3,5-trimethylpyrazine D, 2,4,5-trimethylthiazole E, silica S, cuprous oxide R, grid plate A 30 cm wide strip was formed and evaluated in the same manner as in Example 1, except that compounds (8) and (9) were used instead of compounds (2) and (4).

Similarly, a 50 / 50 mixture of Compounds (7) and (9) was molded into a grid plate. The resulting molded pieces were arranged in a checkerboard pattern and joined together to form a 60 cm wide strip. This was placed on the ground in the form of (Case 2). The deer repellent performance, odor change over time, and odor longevity were then evaluated.

[0079] Example 4 Capsaicin-containing oil G, 3-ethyl-2,5-dimethylpyrazine C, 2,3,5-trimethylpyrazine D, 2,4,5-trimethylthiazole E, activated clay Q, cuprous oxide R, 3D mesh sheet Using a random extrusion three-dimensional mesh manufacturing machine, compound (5) is extruded to a width of 1 m and a basis weight of 1500 g / m. 2 The mixture was molded into a three-dimensional mesh sheet. Similarly, a mixture of compounds (7), (8), and (9) in a weight ratio of 1 / 3 was molded into a three-dimensional mesh sheet. The resulting molded products were stacked and bonded to form a 1-meter-wide strip. This was placed on the ground in the form of (Case 2). Next, the deer repellent performance, change in odor over time, and odor longevity were evaluated.

[0080] <Example 5> Wood tar A, garlic oil F, capsaicin-containing oil G, 2,4,5-trimethylthiazole E, silica S, char T, cuprous oxide R, 3D mesh sheet A 1 m wide strip made of a three-dimensional knitted sheet was formed and evaluated in the same manner as in Example 4, except that a mixture of compounds (1), (2) and (4) in a weight ratio of 1 / 3 was used instead of compound (5), and compound (9) was used instead of compounds (7), (8) and (9).

[0081] Example 6 Wood tar A, garlic oil F, 2,6-dimethylpyrazine B, silica S, char T, cuprous oxide R, rope-like substance In the melt-kneading process for producing pellets of compounds (1), (2), and (6), approximately circular strands with a diameter of 3 mm were prepared for each compound before cutting into pellets. These three types of strands were wound around an existing wire rope to form rope-like objects. These were then installed in a cage with a height of three levels on each side and in the configuration shown in (Case 1). The deer repellent performance, odor change over time, and odor longevity were then evaluated.

[0082] Example 7 Garlic oil F, capsaicin-containing oil G, 2,4,5-trimethylthiazole E, char T, cuprous oxide R, rope-like substance In the melt-kneading process for producing pellets of compounds (2), (4), and (9), approximately circular strands with a diameter of 3 mm were prepared for each compound before cutting into pellets. These three types of strands were twisted into three strands to form rope-like objects. These were then installed on fences at three levels on each side (Case 1). The deer repellent performance, odor change over time, and odor longevity were then evaluated.

[0083] Example 8 Wood tar A, garlic oil F, 2,4,5-trimethylthiazole E, silica S, char T, cuprous oxide R, pellets A bottle with a bottom diameter of 9.5 cm and a height of 23 cm was prepared. The bottle had an opening at the top and was divided into three compartments. 200 g of pellets of Compounds (1), (2), and (9) were placed in each of the three compartments to obtain pellet-containing bottles. These were placed on a fence, one at a time, at 1 m intervals, in the form of (Case 1). The deer repellent performance, changes in odor over time, and odor longevity were then evaluated.

[0084] Example 9 3-Ethyl-2,5-dimethylpyrazine C, 2,3,5-trimethylpyrazine D, 2,4,5-trimethylthiazole E, Cuprous oxide R, Pellets A bottle with a bottom diameter of 9.5 cm and a height of 23 cm and an opening at the top was prepared. 200 g of pellets each of Compounds (7), (8), and (9) were thoroughly mixed and placed in the bottle to obtain a pellet-containing bottle. These were placed on a fence, one at a time, at 1 m intervals, and in the form of (Case 1). The deer repellent performance, change in odor over time, and odor longevity were then evaluated.

[0085] <Comparative Example 1> Wood tar A, lattice board A 75 / 25 (weight ratio) PE / SEPTON mixture was melt-kneaded in a twin-screw kneader, and during the process, 20 parts of wood tar was added to 80 parts of the resin mixture in liquid form, kneaded, cooled, and pelletized to obtain wood tar-containing pellets. Using a general-purpose injection molding machine and mold, the pellets were molded into a lattice plate measuring 30 cm long, 30 cm wide, and 0.5 cm thick.

[0086] Two of the resulting molded articles were stacked and joined to form a 30 cm wide strip. This was then installed on a fence in the form of (Case 1). The deer repellent performance, changes in odor over time, and odor longevity were then evaluated.

[0087] Since the resin mixture of this example did not contain inorganic particles, the wood tar was released quickly and the odor disappeared in a short period of time.

[0088] <Comparative Example 2> Garlic Oil F, 3D mesh sheet A 50 / 50 (weight ratio) mixture of PE / EVA was melt-kneaded in a twin-screw kneader, and during the kneading process, 20 parts of garlic oil was liquid-added to 80 parts of the resin mixture, kneaded, cooled, and pelletized to obtain pellets containing garlic oil. The pellets were then extruded into a 1 m wide, 1500 g / m3 mesh size pelletizer. 2 It was molded into a three-dimensional mesh sheet.

[0089] Two of the resulting molded articles were stacked and joined to form a 1 m wide strip. This was placed on the ground in the form of (Case 2). The deer repellent performance, changes in odor over time, and odor longevity were then evaluated.

[0090] Since the resin mixture of this example did not contain inorganic particles, the garlic oil was released quickly and the odor disappeared in a short period of time.

[0091] <Comparative Example 3> Wood tar A, garlic oil F, capsaicin-containing oil G, lattice board Capsaicin-containing oil-containing pellets were obtained in the same manner as in Comparative Example 1, except that 20 parts of capsaicin-containing oil were used instead of wood tar.

[0092] Using a general-purpose injection molding machine and mold, a 50 / 50 mixture of the garlic oil-containing pellets obtained in Comparative Example 2 and the capsaicin-containing oil-containing pellets was molded into a lattice plate. The lattice plate from Comparative Example 1 and the lattice plate were stacked and bonded to form a 30 cm wide strip. This was installed on a fence in the form of (Case 1). The deer repellent performance, change in odor over time, and odor longevity were then evaluated.

[0093] Since the resin mixture of this example did not contain inorganic particles, the wood tar, garlic oil and capsaicin-containing oil were released at a fast rate, and the odor disappeared in a short period of time.

[0094] <Comparative Example 4> Peppermint Oil H, Char T, Griddle A mixture of PE / SEPTON / char (70 / 20 / 10 by weight) was melt-kneaded in a twin-screw kneader, and 20 parts of peppermint oil was added to 80 parts of the resin mixture during the kneading process. The mixture was then cooled and pelletized to obtain pellets containing peppermint oil and char. The pellets were molded into a lattice plate measuring 30 cm long, 30 cm wide, and 0.5 cm thick using a general-purpose injection molding machine and mold.

[0095] Two of the resulting molded articles were stacked and joined to form a 30 cm wide strip. This was then installed on a fence in the form of (Case 1). The deer repellent performance, changes in odor over time, and odor longevity were then evaluated.

[0096] Peppermint oil evaporates relatively easily, making it difficult to maintain its odor for a long period of time, and it was confirmed that it is unsuitable as a repellent for the present invention.

[0097] <Comparative Example 5> Allyl isothiocyanate I, Char T, Grid plate A 30 cm wide strip was formed and evaluated in the same manner as in Comparative Example 4, except that 10 parts of allyl thioisocyanate was used instead of peppermint oil.

[0098] Since allyl isothiocyanate evaporates relatively easily, it is difficult to maintain the odor for a long period of time, and it was confirmed that it is unsuitable as a repellent for the present invention.

[0099] <Comparative Example 6> Denatonium Benzoate J, Char T, Grid Plate A 30 cm wide strip was formed and evaluated in the same manner as in Comparative Example 4, except that 20 parts of denatonium benzoate was used instead of peppermint oil.

[0100] Denatonium benzoate stimulates the taste buds but has no noticeable odor, and it was confirmed that it is unsuitable as a repellent for use in the present invention.

[0101] <Comparative Example 7> Capsaicin-containing oil G, activated carbon U, 3D mesh sheet A mixture of PE / EVA / activated carbon = 40 / 40 / 10 (weight ratio) was melt-kneaded in a twin-screw kneader, and during the kneading process, 20 parts of capsaicin-containing oil was liquid-added to 80 parts of the resin mixture, kneaded, cooled, and pelletized to obtain pellets containing capsaicin-containing oil and activated carbon. The pellets were then extruded into a 1 m wide, 1500 g / m3 mesh size pelletizer using a random extrusion three-dimensional mesh manufacturing machine. 2 It was molded into a three-dimensional mesh sheet.

[0102] Two of the resulting molded articles were stacked and joined to form a 1 m wide strip. This was placed on the ground in the form of (Case 2). The deer repellent performance, changes in odor over time, and odor longevity were then evaluated.

[0103] Since activated carbon has a high adsorption capacity, it inhibits the evaporation of capsaicin-containing oil, and it was confirmed that activated carbon is unsuitable as inorganic particles for use in the present invention.

[0104] <Comparative Example 8> Capsaicin-containing oil G, glass beads V, 3D mesh sheet A 1 m wide strip was formed and evaluated in the same manner as in Comparative Example 7, except that 10 parts by weight of glass beads were used instead of activated carbon.

[0105] It was confirmed that glass beads have low surface activity and therefore are not effective in contributing to the sustained release of capsaicin-containing oil, and are therefore unsuitable as inorganic particles for use in the present invention.

[0106] <Comparative Example 9> Capsaicin-containing oil G, aluminum powder W, 3D mesh sheet A 1 m wide strip was formed and evaluated in the same manner as in Comparative Example 7, except that 10 parts by weight of aluminum powder was used instead of activated carbon.

[0107] It was confirmed that aluminum powder has low surface activity and therefore is not effective in contributing to the sustained release of capsaicin-containing oil, and is therefore unsuitable as inorganic particles for use in the present invention.
