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 animals have also become feral, and in recent years there have been an increasing number of cases of them invading areas of human activity and causing harm. For example, there has been an increase in so-called roadkill, where wild deer enter roads or railway tracks and collide with vehicles. Damage to agricultural 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, capsaicin, wood tar, herbs, garlic, the hair, blood, and excrement of predators such as wolves and bears, and vinegar are known and used as natural repellents that stimulate the taste and smell of animals and are also environmentally friendly (Patent Documents 1 and 2).

[0004] [Patent Document 1] JP 2014-210791 A [Patent Document 2] Patent No. 6224691 Summary of the Invention [Problem to be solved by the invention]

[0005] However, since many of the conventional animal repellents are liquid, there is a problem that it is difficult to handle and to place the liquid in a specified place. For example, a liquid repellent can be converted into an article that is easy to handle by impregnating or retaining it in a solid substrate. However, under outdoor exposure conditions, the repellent is likely to flow out or evaporate early, and the issue of such an article is how to extend the duration of the repellent performance. In addition, there is also a 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 object is to provide an animal repellent resin composition that can realize 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, there is provided an animal repellent resin composition which can realize 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. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] An embodiment of the present invention will be described in detail below, 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. In addition, when multiple upper and lower limit values ​​are described 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 when heated 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 to a solid at room temperature and can be shaped into a desired shape. As a result, the handling of the animal repellent is improved.

[0020] The thermoplasticity of the thermoplastic resin is represented by the softening point of the resin. In order to suppress the transpiration loss in 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 and the release of the animal repellent is promoted, so that the effective life of the animal repellent article is likely to decrease. In addition, if the softening point exceeds 120°C, the transpiration loss of the animal repellent occurs when kneading into the thermoplastic resin, or the hardness at room temperature increases and the release of the animal repellent is suppressed, so that the repellent effect of the animal repellent article is likely to decrease.

[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 is the softening point of the thermoplastic resin that forms the matrix of the animal repellent resin composition.

[0022] Examples of types 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 them, the preferred thermoplastic resin is a thermoplastic resin described in Japanese Patent No. 3963941, which forms a liquid-in-solid polymer emulsion by incorporating a liquid compound (C) therein. The contents of this publication are all incorporated herein by reference.

[0023] The thermoplastic resin is a mixed resin containing a thermoplastic polymer (A) forming a matrix and a block copolymer (B) forming a domain, and (B) is composed of a block (B1) having high compatibility with (A) and low compatibility with a liquid compound (C) and a block (B2) having high compatibility with (C) and low compatibility with (A), and is phase-separated from (A).

[0024] In such a thermoplastic resin, the block copolymer (B) acts as a surfactant and forms 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 form 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] 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 refer to porous inorganic particles having a porous structure consisting of a large number of pores on the high-order surface. The porous inorganic particles may be in powder form. The pores of the porous inorganic particles store and retain the animal repellent, suppressing premature leakage or evaporation from the matrix resin. As a result, the animal repellent resin molded article can exhibit a sustained-release effect of releasing the animal repellent over a long period of time.

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

[0030] (Fly ash) The fly ash referred to here refers to ash obtained by burning charcoal or silica-alumina composite particles. Fly ash may also be finely powdered coal ash generated in thermal power plants where coal is burned 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 is mainly composed of silicon oxide and has a porous structure. As the porous silica, either vapor-phase silica or wet silica may be used.

[0034] (Char) Char is a black powder containing 80% or more by weight of carbon components that 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, a preferred controlled release inorganic particle is char.

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

[0037] The sustained release inorganic particles have a primary particle size of 0.01 to 50 μm, with an average particle size D 50 It is preferable that the sustained-release inorganic particles have an average particle size of less than 0.01 μm, which is likely to cause thermal aggregation during the kneading and molding processes and result in a state lacking in uniform dispersion, and 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% by weight based on the entire animal repellent resin composition. If the content of the sustained-release inorganic particles is less than 0.5% by weight, the sustained-release effect of the animal repellent resin molding article decreases, and if it exceeds 30% by weight, the compound has poor fluidity when melted, which deteriorates the efficiency of melt molding and reduces the strength of the animal repellent molding. The content of the sustained-release inorganic particles is more preferably 1.0 to 20% by weight, and even more preferably 5.0 to 10% by weight.

[0039] (C) Animal repellents The animal repellent is a repellent for wild animals and harmful animals that, when volatilized, produces 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 been used for the same purpose in the past. Specific examples of preferred animal repellents are shown below.

[0040] (Wood tar) Wood tar is a liquefied form of 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 are compounds contained in wolf urine, and their odor scares off pests and other animals, preventing them from coming near.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 of 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 active ingredient capsaicin 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 being easily evaporated from the retained state. The animal repellent may be used alone or in combination of two or more kinds.

[0046] The content of the animal repellent is preferably 1.0 to 20% by weight based on the entire 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 the sustained release inorganic particles and the animal repellent with a thermoplastic resin using a normal heating and kneading device, liquefying the thermoplastic resin, kneading the blend until it becomes uniform, and cooling it. In this case, the method of kneading a liquid repellent described in Japanese Patent No. 3963941 and Japanese Patent No. 4576479 may be used.

[0048] For example, using a general twin-screw resin kneading extruder, first, a thermoplastic resin is fed from a resin pellet feed hopper and sent by a screw while being heated above the melting point of the resin. Then, sustained-release inorganic particles are fed from a downstream powder feed hopper and kneaded into the molten thermoplastic resin. An animal repellent is added to the kneaded mixture from a plunger pump or the like, and further kneaded to disperse it uniformly. The kneaded mixture is then extruded from a die head, the strands are passed through water to cool, and cut with a cutter to form pellets.

[0049] <Animal repellent resin molded body, animal repellent resin molded body article> The obtained pellets are kneaded using an extruder, and then poured into a mold attached to the tip of the extruder for injection molding to produce an animal repellent resin molded body having a desired shape. Instead of molding into pellets, the molten animal repellent resin composition may be directly poured into a mold from the extrusion process to perform injection molding. The shape of the animal repellent resin molded body produced by the injection molding method may be, for example, a mesh plate or a lattice plate having breathability. The animal repellent resin molded body may be, for example, a pellet or a molten animal repellent resin molded body molded into a three-dimensional mesh sheet using a random extrusion three-dimensional mesh manufacturing machine that draws threads from a molten resin at high speed and crosses the threads to form a three-dimensional mesh.

[0050] These animal repellent resin molded articles can be made either alone or in combination. For example, the mesh plate, lattice plate, and three-dimensional mesh sheet animal repellent resin compositions can be laminated together to make an animal repellent resin molded article containing multiple types of animal repellents. In this case, when an animal steps on the animal repellent resin molded article, the layers themselves and the multiple types of repellents trapped in the spaces between the layers are released into the atmosphere, 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 habituated to a particular combination of repellents, it is possible to easily change to a different combination, thereby suppressing habituation.

[0052] In addition, by combining two or more types of animal repellents, the evaporation rate of each repellent differs, and the quality of the odor emitted from the animal repellent molded article changes over time. As a result, wild animals that are becoming accustomed to the initial odor will perceive the change in odor quality as a new stimulus, and acclimatization can be suppressed.

[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, which 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 do not like the odor of the animal repellent and are repelled by it. 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 them, the mammals against which the animal repellent molded article of the present invention is considered to be effective are deer, wild boars, raccoon dogs, foxes, raccoons, palm civets, etc. EXAMPLES

[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]

The pellets were further mixed at a weight ratio of 90 / 10 to char, kneaded in a twin-screw kneader, cooled, and pelletized to obtain pellets containing garlic oil and char.

[0062] Compound (3): Garlic Oil F + Fly Ash P Pellets containing garlic oil and fly ash were obtained in the same manner as compound (2), except that fly ash was used instead of char.

[0063] Compound (4): Capsaicin-containing oil G + Char T Pellets containing capsaicin-containing oil and char were obtained in the same manner as in compound (2), except that capsaicin-containing oil was used instead of garlic oil.

[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 that had been heated to 40°C or higher and melted was mixed with 80 parts of EVA resin at an ambient temperature of 40°C, and stirred to allow swelling and absorption to obtain pellets. The pellets were mixed in a weight ratio of 44.5 / 44.5 / 1.0 (pellets / PE / cuprous oxide), 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 mixed with 80 parts of EVA resin, and the mixture was stirred to allow the resin to swell and absorb, obtaining pellets.

[0068] Compound (9): 2,4,5-trimethylthiazole E + Cuprous oxide R Pellets containing 2,4,5-trimethylthiazole and cuprous oxide were obtained in the same manner as in compound (7), except that 2,4,5-trimethylthiazole was used instead of 3-ethyl-2,5-dimethylpyrazine.

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

[0070] - Form of installing the 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 a width equal to the entrance surface.

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

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

[0073] Determination of 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 deterrent structure was not installed, and M is the number of deer that entered the fence to eat bait when the deterrent structure was installed.

[0075] <Method of evaluating odor change over time and odor lifespan> The inventors performed a sensory evaluation and recorded the quality and strength of the odor perceived by standing 5 m away from the repellent structure installed on the fence every 30 days to determine 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, charcoal T, lattice board Using a general-purpose injection molding machine and mold, compound (1) was molded into a lattice plate 30 cm long, 30 cm wide and 0.5 cm thick. In the same manner, compounds (2) and (4) were mixed in a weight ratio of 50 / 50 and molded into a lattice plate. The resulting molded products 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, the change in odor over time, and the odor lifespan 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 the compounds (8) and (9) were used instead of the compounds (2) and (4).

In the same manner, a mixture of compounds (7) and (9) in a weight ratio of 50 / 50 was molded into a lattice plate. The resulting molded pieces were arranged in a checkerboard pattern and joined together to form a strip 60 cm wide. This was placed on the ground in the form of (Case 2). The deer repellent performance, the change in odor over time and the lifespan of the odor 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, three-dimensional 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 In the same manner, compounds (7), (8) and (9) were mixed in a weight ratio of 1 / 3 and molded into a three-dimensional mesh sheet. The resulting molded products were stacked and joined to form a strip 1 m wide. This was placed on the ground in the form of (Case 2). Next, the deer repellent performance, the change in odor over time and the odor lifespan 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, three-dimensional 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 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 before cutting into pellets. These three types of strands were wound around an existing wire rope to form a rope-like object. This was installed in a cage with a height of three stages on each side and in the form of (Case 1). Next, the deer repellent performance, the change in odor over time and the lifespan of the odor were 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 before cutting into pellets. These three types of strands were twisted in three to form rope-like objects. These were installed on fences at three levels on each side and (Case 1). The deer repellent performance, change in odor over time and odor lifespan 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 an opening at the top, an inside divided into three compartments, a bottom diameter of 9.5 cm, and a height of 23 cm was prepared. 200 g of pellets of compounds (1), (2), and (9) were stored in each of the three compartments of the bottle to obtain a pellet-containing bottle. These were placed on a fence one by one at 1 m intervals and in the form of (Case 1). Next, the deer repellent performance, the change in odor over time, and the lifespan of the odor were 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, which has an opening at the top, was prepared. 200 g each of pellets of compounds (7), (8) and (9) were thoroughly mixed and stored in the bottle to obtain a pellet-containing bottle. This was placed on a fence one by one at intervals of 1 m and in the form of (Case 1). Next, the deer repellent performance, the change in odor over time and the lifespan of the odor were evaluated.

[0085] <Comparative Example 1> Wood tar A, lattice board A mixture of PE / SEPTON = 75 / 25 (weight ratio) was melt-kneaded in a twin-screw kneader, and during the process, 20 parts of wood tar was added as a liquid to 80 parts of the resin mixture, 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 30 cm long, 30 cm wide, and 0.5 cm thick.

[0086] Two pieces of the obtained molded product were stacked and joined to form a 30 cm wide strip. This was installed on a fence in the form of (Case 1). Next, the deer repellent performance, the change in odor over time, and the longevity of the odor were evaluated.

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

[0088] <Comparative Example 2> Garlic Oil F, 3D Mesh Sheet A mixture of PE / EVA = 50 / 50 (weight ratio) was melt-kneaded in a twin-screw kneader, and during the kneading, 20 parts of garlic oil was added to 80 parts of the resin mixture as a liquid, kneaded, cooled, and pelletized to obtain pellets containing garlic oil. The pellets were then cut into pieces with a width of 1 m and a basis weight of 1500 g / m using a random extrusion three-dimensional mesh manufacturing machine. 2 It was molded into a three-dimensional mesh sheet.

[0089] Two pieces of the obtained molded product were stacked and joined to form a 1 m wide strip. This was placed on the ground in the form of (Case 2). Next, the deer repellent performance, the change in odor over time, and the longevity of the odor were evaluated.

[0090] Since the resin mixture of this example did not contain inorganic particles, the garlic oil was released quickly and the odor disappeared within 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, the pellets containing garlic oil obtained in Comparative Example 2 and the pellets containing capsaicin-containing oil were mixed in a weight ratio of 50 / 50 and molded into a lattice plate. The lattice plate of Comparative Example 1 and the lattice plate were stacked and bonded to form a strip-shaped object with a width of 30 cm. This was installed on a fence in the form of (Case 1). Next, the deer repellent performance, the change in odor over time, and the lifespan of the odor were 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 within a short period of time.

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

[0095] Two pieces of the obtained molded product were stacked and joined to form a 30 cm wide strip. This was installed on a fence in the form of (Case 1). Next, the deer repellent performance, the change in odor over time, and the longevity of the odor were evaluated.

[0096] Since peppermint oil evaporates relatively easily, it is difficult to maintain the odor for a long period of time, and it has been confirmed that peppermint oil 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 has been 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 were used instead of peppermint oil.

[0100] Denatonium benzoate stimulates the taste but has no detectable odor, and it has been 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 melted and kneaded in a twin-screw kneader, and during the process, 20 parts of capsaicin-containing oil was added to 80 parts of the resin mixture as a liquid, kneaded, cooled, and pelletized to obtain pellets containing capsaicin-containing oil and activated carbon. The pellets were cut into pieces with a width of 1 m and a basis weight of 1500 g / m using a random extrusion three-dimensional mesh manufacturing machine. 2 It was molded into a three-dimensional mesh sheet.

[0102] Two pieces of the obtained molded product were stacked and joined to form a 1 m wide strip. This was placed on the ground in the form of (Case 2). Next, the deer repellent performance, the change in odor over time, and the longevity of the odor were 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 the 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 the 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.
