Abstract
Description
本発明は、防蟻剤とその製造方法に関し、詳しくは、建築物の床下空間などに施工されて、白蟻の侵入を阻止する防蟻剤と、このような防蟻剤を製造する方法とを対象にしている。 The present invention relates to an ant-proofing agent and a method for producing the same, and more specifically, an ant-proofing agent that is installed in an underfloor space of a building and prevents the entry of white ants, and a method for producing such an ant-proofing agent. It is targeted.
住宅などの建築物の床下空間に、粉状あるいは液状の防蟻剤を散布したり、防蟻剤が配合された合成樹脂シートを敷いたり、防蟻剤が配合された発泡ボードを基礎構造の表面に貼り付けたりして、地盤から床下空間を経て建築物の上部構造にまで白蟻が侵入することを阻止することが行われている。
このような防蟻技術において使用される防蟻剤には、化学的に合成された防蟻機能を有する化合物や、ヒバ油などの天然の防蟻作用を有する薬剤がある。
防蟻剤は、その機能からも予想されるように、生物に対して毒性を有する成分や環境を汚染する可能性のある成分が含まれており、その取扱いには注意が必要とされる。高濃度の防蟻剤をそのまま露出させた状態で使用したり、防蟻剤を高濃度で含有する部材が露出状態になったりすることは避けなければならない。そこで、防蟻剤となる化合物を、水に分散させたり溶媒に溶解させたりして希釈液の状態で使用することが行われている。防蟻剤の希釈液を、発泡ボードの成形材料などに配合すれば、直接に高濃度の防蟻剤を取り扱うことなく、所定の防蟻機能を有する製品が得られる。
Sprinkle powder or liquid ant protection agent in the underfloor space of a building such as a house, lay a synthetic resin sheet containing ant protection agent, or use foam board with ant protection agent Pasting it on the surface to prevent white ants from penetrating from the ground through the underfloor space to the superstructure of the building.
Examples of the ant control agents used in such ant control technology include chemically synthesized compounds having ant control functions and natural ant control agents such as hiba oil.
As expected from its function, the termite-proofing agent contains components that are toxic to living organisms and components that may contaminate the environment, and handling thereof requires caution. It must be avoided that a high concentration of the termite-proofing agent is used as it is, or that a member containing the high concentration of the termite-proofing agent is exposed. In view of this, it has been practiced to use a compound as an antifungal agent in a diluted state by dispersing it in water or dissolving it in a solvent. If a dilute solution of an ant-repellent is blended in a molding material for foamed board, a product having a predetermined ant-repellent function can be obtained without directly handling a high concentration of the ant-repellent.
特許文献１には、床下断熱材などに利用される発泡ポリスチレンなどの断熱ボードに対する白蟻の食害を防止するために、発泡ポリスチレンなどの押出成形時に、溶融樹脂に防蟻剤を添加しておく技術が提案されている。
特許文献２には、防蟻剤を含有する発泡樹脂成形体の製造方法として、予備発泡させたポリスチレン樹脂や未発泡のポリスチレンビーズへ、防蟻剤を含む溶液を流動塗装などでコーティングしておく技術が提案されている。
特許文献３には、発泡ポリウレタン樹脂成形体の原料になる発泡剤を含むポリオールに、防蟻剤のポリオール溶液や水分散液を添加しておく技術が提案されている。
In Patent Document 2, as a method for producing a foamed resin molded article containing an ant-proofing agent, a solution containing the ant-proofing agent is coated on a pre-foamed polystyrene resin or an unfoamed polystyrene bead by fluid coating or the like. Technology has been proposed.
Patent Document 3 proposes a technique in which a polyol solution or an aqueous dispersion of an anti-anticide is added to a polyol containing a foaming agent that is a raw material for a foamed polyurethane resin molded article.
前記した従来における防蟻剤の使用形態では、防蟻剤の機能を十分に発揮させ難いという問題がある。
前記した特許文献１のように、発泡樹脂の成形材料に防蟻剤を配合しておく場合、成形材料に均一に防蟻剤を分散させることが難しい。例えば、通常の建築用途に使用される防蟻発泡ボードの場合、防蟻剤を発泡樹脂全体の０．１重量％などという極めて少ない割合で配合しなければならない。当然、成形材料に加える防蟻剤の量も微量になるため、成形剤量の全体に均一に防蟻剤を分散させるのが難しい。発泡樹脂の押出成形装置で、樹脂を溶融混練するシリンダ内に、少量の防蟻剤を添加する場合、防蟻剤の一部が装置内壁などに付着したままになるだけでも、発泡樹脂に対する防蟻剤の含有量が大きく違ってくる。少量の防蟻剤が樹脂全体に均等に分散されるまで溶融混合するには、長い時間がかかり、製造能率が低下してしまう。発泡ボードの連続成形装置では、成形装置に微量の防蟻剤を一定量づつ連続的に供給する装置を追加しなければならない。この防蟻剤の供給装置や成形装置への供給路などは、防蟻剤が漏れないように、厳重な安全対策や密封構造が必要であり、装置が複雑になる。
The above-described conventional use form of the ant-preventing agent has a problem that it is difficult to sufficiently exert the function of the ant-preventing agent.
As described in Patent Document 1, in the case where an antifungal agent is blended in the foamed resin molding material, it is difficult to uniformly disperse the antifungal agent in the molding material. For example, in the case of an ant-proof foam board used for a normal building application, the ant-proof agent must be blended in an extremely small proportion such as 0.1% by weight of the entire foamed resin. Naturally, since the amount of the termite-preventing agent added to the molding material is very small, it is difficult to disperse the termite-preventing agent uniformly throughout the amount of the molding agent. When a small amount of an anti-bacterial agent is added to a cylinder for melting and kneading the resin in a foamed resin extrusion molding device, even if a part of the anti-bacterial agent remains attached to the inner wall of the device, etc., The content of ant is greatly different. It takes a long time to melt and mix until a small amount of the termite-proofing agent is uniformly dispersed throughout the resin, resulting in a reduction in production efficiency. In the continuous forming apparatus for the foam board, a device for continuously supplying a small amount of the termite-proofing agent to the forming apparatus in a certain amount must be added. The supply system for the termite-proofing agent and the supply path to the molding device require strict safety measures and a sealing structure so that the termite-proofing agent does not leak, which complicates the device.
特許文献２のように、予めポリスチレンビーズに防蟻剤溶液をコーティングしておくには、そのための特別な装置が必要になる。一つ一つのポリスチレンビーズに均一に防蟻剤が付着するようにコーティングするのは、かなり高度な技術が必要である。このとき、ポリスチレンビーズの特性や成形性を損なわないように、防蟻剤をコーティングすることも難しい。しかも、特別な防蟻剤溶液を調製する作業が増えるとともに、調製された防蟻剤溶液は、ポリスチレンビーズへのコーティングだけにしか使用できず。他の用途に転用し難い。専用の防蟻剤溶液は、それだけコストが高くつく。防蟻剤を水に分散させるだけであれば、比較的に作業は容易であるが、一般的な防蟻剤は何れも、水に均一に分散させるのが難しい。防蟻剤の水分散液を、樹脂成形などに利用するまで保管しておくと、防蟻剤が沈降したり浮き上がったりして、均一な分散状態を維持することが難しい。 As in Patent Document 2, in order to previously coat the polystyrene beads with the anti-repellent agent solution, a special device for that purpose is required. It is necessary to use a highly advanced technique for coating each polystyrene bead so that the termite-proofing agent is uniformly attached. At this time, it is also difficult to coat the termite-proofing agent so as not to impair the properties and moldability of the polystyrene beads. Moreover, as the number of operations for preparing a special ant inhibitor solution increases, the prepared ant inhibitor solution can be used only for coating polystyrene beads. Difficult to divert to other uses. A dedicated anti-anticide solution is expensive. If the termite-proofing agent is simply dispersed in water, the operation is relatively easy, but it is difficult to uniformly disperse any common termite-proofing agent in water. If the water-dispersed solution of the termite-proofing agent is stored until it is used for resin molding or the like, it is difficult for the termite-proofing agent to settle or float up and maintain a uniform dispersion state.
防蟻成分の粉末を別の粉末材料で希釈した希釈粉末であれば、比較的に製造は容易である。ところが、単なる粉末の混合物の場合、防蟻成分と他の粉末材料との配合割合が、場所によって大きく偏ることがある。特に、輸送や保管の間に振動や衝撃が繰り返されると、粒径や粒形状の違いによって、防蟻成分の偏在が顕著に発生する。このような防蟻成分の含有量にバラツキが多い防蟻剤を使用して、前記した発泡ボードの成形を行うと、得られた防蟻発泡ボードは、防蟻成分が高濃度で存在するところと、防蟻成分がほとんど存在しないところができてしまう。建築物に施工したときには、白蟻が、防蟻発泡ボードのうち、防蟻成分が存在しない個所だけを食い破って侵入してくることになる。防蟻発泡ボードなどの防蟻建築材は、たとえ一部でも、防蟻機能に劣り白蟻の食害や侵入が容易な個所があると、実質的に防蟻機能が果たせないことになり、商品価値は大きく損なわれる。 If it is a diluted powder obtained by diluting the ant-preventive component powder with another powder material, the production is relatively easy. However, in the case of a simple powder mixture, the blending ratio of the termite-preventing component and the other powder material may be greatly biased depending on the location. In particular, when vibrations and impacts are repeated during transportation and storage, uneven distribution of the termite-preventing component occurs remarkably due to the difference in particle size and particle shape. When the above-mentioned foamed board is molded using such an antproofing agent having a large variation in the content of the antproofing component, the obtained antproofing foam board has a high concentration of the antproofing component. Then, there will be a place where there is almost no ant-proof component. When constructed in a building, white ants will invade only the parts of the ant-proof foam board that do not have ant-proof components. Ant-proof building materials such as ant-proof foam boards, even if there are parts that are inferior to the ant-proof function and are easy to eat and invade white ants, will not be able to perform the ant-proof function substantially, and the product value Is greatly impaired.
本発明の課題は、防蟻成分が均等に安定して配合され、輸送保管などと取扱いによっても防蟻成分の含有量にバラツキが生じず、防蟻製品の製造および防蟻施工が行い易く、高い防蟻機能を発揮させることのできる防蟻剤を提供することである。 The problem of the present invention is that the ant-preventive ingredients are evenly and stably blended, and the content of the ant-preventive ingredients does not vary depending on transportation and storage, etc. An object of the present invention is to provide an ant-proofing agent capable of exhibiting a high ant-proofing function.
本発明にかかる防蟻剤は、無機材料の粉体に防蟻成分が複合一体化されてなり、前記防蟻成分が０．０１〜３０重量％含まれ、平均粒径０．１〜２００μｍの粒状をなす。

Natural products: Capric acid, Hiba neutral oil, Turmeric.
Examples of the termite-preventing component that can be preferably used in the present invention include imidacloprid, silafluophene, and bifenthrin.
The ant-proof component may be a solid such as powder or a liquid. In order to facilitate the composite integration by the mixing and pulverizing process described later, the powdery ant-proof component preferably has an average particle size of 0.1 to 200 μm. Those having an average particle diameter of 1 to 80 μm are more preferable. However, the average particle size defined here is defined for the raw material at the stage before being supplied to the composite integration process. In some cases, the average particle diameter of the ant-preventive components constituting the ant-repellent after the composite integration process is different.
〔無機材料の粉体〕
防蟻成分と複合一体化することが可能で、防蟻成分の機能を阻害せず、生物や環境への悪影響が少ない無機材料からなるものが使用される。一般的に、有機材料よりも無機材料のほうが、これらの条件を満足するものが多い。
具体的には、カオリン、クレー、炭酸カルシウム、タルク、マイカ、シリカ、珪藻土、ゼオライト、ベントナイト、窒化ホウ素、炭化ケイ素、窒化ケイ素が挙げられる。これらの無機材料は、単独で使用してもよいし、複数種類を組み合わせて使用することもよい。
防蟻剤を発泡樹脂などの製造工程中に配合して使用する場合、その製造工程において無機粉末が変質したり分解したり製造に有害な影響を与えたりしない材料が好ましい。例えば、樹脂成形時の高熱に耐える耐熱性を有することが望ましい。また、防蟻剤の使用形態で要求される種々の使用条件を満足することも必要である。例えば、建築物に使用する場合は、難燃性の材料が好ましい。
[Inorganic material powder]
A material made of an inorganic material that can be combined and integrated with the ant-proofing component, does not impair the function of the ant-proofing component, and has little adverse effect on living things and the environment is used. In general, more inorganic materials satisfy these conditions than organic materials.
Specific examples include kaolin, clay, calcium carbonate, talc, mica, silica, diatomaceous earth, zeolite, bentonite, boron nitride, silicon carbide, and silicon nitride. These inorganic materials may be used alone or in combination of a plurality of types.
In the case where the termite-proofing agent is blended and used during the manufacturing process of foamed resin or the like, a material that does not alter or decompose the inorganic powder or adversely affect the manufacturing in the manufacturing process is preferable. For example, it is desirable to have heat resistance that can withstand high heat during resin molding. Moreover, it is also necessary to satisfy various usage conditions required for the usage form of the termite-proofing agent. For example, when used for a building, a flame retardant material is preferable.
防蟻成分が粉体の場合、無機材料の粒径は、防蟻成分の粒径よりも大きく設定しておくことが好ましい。複合一体化された防蟻剤の状態で、無機材料の粉体粒子表面などの一部に防蟻成分が存在する状態になる。複合一体化工程に供する段階の無機材料の平均粒径を、０．１〜２００μｍに設定できる。
〔防蟻剤の製造〕
無機材料の粉体に防蟻成分を複合一体化させることができれば、通常の、粉体同士の複合一体化手段や粉体と液体との複合一体化手段が適用できる。
具体的には、ボールミル、遊星回転ミル、衝撃式粉砕機などの混合粉砕装置を用いて、無機材料の粉体に防蟻成分とを撹拌混合して、粉砕と同時に無機材料の粉体に防蟻成分を複合一体化させることができる。無機材料の粉体あるいは防蟻成分の粉体が混合粉砕されるときの生じる摩擦力や衝撃力、剪断力、熱応力などの作用で、無機材料の粉体と防蟻成分の粉体とが、物理的あるいは化学的に結合することで、複合一体化が生じる。このような複合一体化が生じるような撹拌強度や処理時間などを設定する。特別なバインダーや接着剤成分を使用しなくても、無機材料の粉体と防蟻成分の粉体とを複合一体化することが可能である。但し、補助的に、バインダー成分などを加えておくことはできる。処理条件を適切に設定することで、得られる防蟻剤の粒径とその分布、防蟻剤粒子における無機材料への防蟻成分の複合化状態などが調整できる。
When the ant-proof component is powder, the particle size of the inorganic material is preferably set larger than the particle size of the ant-proof component. In the state of the compounded and integrated anti-repellent agent, the anti-ant component is present in a part of the powder particle surface of the inorganic material. The average particle diameter of the inorganic material at the stage of being subjected to the composite integration process can be set to 0.1 to 200 μm.
[Manufacture of ant-proofing agents]
As long as the ant protection component can be combined and integrated with the powder of the inorganic material, a normal composite integration means of powders or a composite integration means of powder and liquid can be applied.
Specifically, using a mixing pulverizer such as a ball mill, a planetary rotating mill, or an impact pulverizer, the inorganic material powder is agitated and mixed with the ant-preventive component, and simultaneously with the pulverization, the inorganic material powder is protected. Ant components can be combined and integrated. Due to the effects of friction, impact, shearing force, thermal stress, etc. that occur when inorganic material powder or ant-preventive component powder is mixed and pulverized, inorganic material powder and ant-preventive component powder are separated. Combined physically or chemically, composite integration occurs. The agitation intensity, processing time, etc. are set such that such complex integration occurs. Without using a special binder or adhesive component, the inorganic material powder and the ant-proof component powder can be combined and integrated. However, a binder component or the like can be added in an auxiliary manner. By appropriately setting the treatment conditions, it is possible to adjust the particle size and distribution of the obtained termite-proofing agent, the compounded state of the termite-proofing component in the inorganic material in the termite-proofing agent particles, and the like.
防蟻剤の製造時に、無機材料の粉体および防蟻成分に加えて、別の材料を配合して、同時に複合一体化させることもできる。例えば、前記したバインダーや接着剤成分のほか、着色剤や香料などが挙げられる。
〔防蟻剤〕
得られた防蟻剤は、無機材料の粉体に防蟻成分が複合一体化された粒状物である。
粒子形状や複合構造は、使用する材料や製造条件によって異なる。通常は、不定形な粒状をなす。無機材料の粉体を主体にして、その表面の一部、あるいは、内部の一部に、防蟻成分が点在する状態である。なお、工業的に生産される防蟻剤製品では、不可避的に生成する無機材料あるいは防蟻成分の単独粒子が少量は存在していることもある、
防蟻剤の粒径は、製造条件によって変更でき、使用形態に適した粒径に設定できる。通常は、平均粒径０．１〜２００μｍの範囲に設定される。好ましくは、平均粒径１〜８０μｍである。防蟻剤を粒状のままで散布したりして使用する場合と、発泡樹脂に配合して使用する場合などでは、好ましい粒径範囲は異なる可能性がある。
In addition to the inorganic material powder and the ant protection component, another material can be blended at the time of manufacturing the ant protection agent, and simultaneously combined and integrated. For example, in addition to the binder and adhesive component described above, a coloring agent, a fragrance, and the like can be given.
[Anti-anticide]
The obtained termite-proofing agent is a granular material in which the termite-proofing component is combined and integrated with powder of an inorganic material.
The particle shape and composite structure vary depending on the materials used and the manufacturing conditions. Usually, it has an irregular grain shape. This is a state in which an inorganic material powder is mainly used, and ant-proof components are scattered on a part of the surface or a part of the inside thereof. In addition, in industrially produced ant protection products, there may be a small amount of single particles of inorganic materials or ant protection components that are inevitably produced,
The particle size of the termite-proofing agent can be changed depending on the production conditions, and can be set to a particle size suitable for the usage form. Usually, the average particle size is set in the range of 0.1 to 200 μm. The average particle diameter is preferably 1 to 80 μm. The preferred particle size range may be different depending on whether the ant-proofing agent is used after being sprayed in a granular form or when used in a foamed resin.
防蟻剤には、少なくとも目的とする防蟻機能が発揮できるだけの量で防蟻成分が含まれる。具体的には、防蟻成分を０．０１〜３０重量％含有させる。好ましくは、０．１〜１０重量％である。防蟻剤を直接に散布して使用する場合と発泡樹脂に配合して使用する場合などでは、防蟻剤に含有させる防蟻成分の割合を変更しておくことができる。
〔防蟻剤の使用〕
防蟻剤は、通常の粒状をなす防蟻剤と同様の用途に同様の使い方で使用することができる。
防蟻剤は、防蟻成分の含有量が比較的に少ないので、輸送や保管などの取扱いに、それほど厳重な安全対策を講じる必要がない。しかも、粒状をなしているので、液状の防蟻剤に比べて、輸送保管時に漏れや染み出しなどが起こり難く、取扱いが容易である。
The termite-proofing agent contains the termite-proofing component in an amount that can at least exert the intended termite-proofing function. Specifically, 0.01-30% by weight of an ant-proof component is contained. Preferably, it is 0.1 to 10% by weight. The ratio of the ant-preventive component to be contained in the ant-preventing agent can be changed in the case where the ant-preventing agent is directly sprayed and used, or in the case where it is blended and used in the foamed resin.
[Use of anti-anticide]
The termite-proofing agent can be used in the same way for the same use as that of a conventional grain-shaped termite-proofing agent.
Since the content of the ant preventive agent is relatively small, it is not necessary to take strict safety measures for handling such as transportation and storage. In addition, since it is granular, it is less likely to leak or ooze out during transportation and storage, and is easy to handle, as compared to liquid ant preventives.
具体的な使用形態としては、建築物の床下空間で地盤と基礎構造との境界部分に防蟻剤を堆積させておいたり、床下地面に散布したり、地盤に掘った溝に充填しておいたりすることができる。このような使用形態の場合、粒状の防蟻剤を粘性液体に配合して、まとまりの良いクリーム状あるいは練状物の形態にしてから使用することもできる。
防蟻剤を、建築部材などを成形製造する成形材料の一部に配合しておけば、防蟻剤が配合された建築部材などの成形品が得られる。
具体的には、発泡樹脂の押出成形時に、成形材料である発泡性樹脂ビーズに粒状の防蟻剤を混合しておいたり、押出装置内で溶融混練状態の樹脂に粒状の防蟻剤を加えたりすることができる。勿論、発泡樹脂ではない通常の樹脂成形にも適用できるし、押出成形以外の型内成形や射出成形などにも適用できる。
Specific usage forms include depositing an antifungal agent at the boundary between the ground and the foundation structure in the space under the building, spraying it on the ground floor, or filling a groove dug in the ground. Can be. In the case of such a usage form, it is also possible to use a granular ant preventive agent after blending it into a viscous liquid to form a cohesive cream or kneaded product.
If the termite-proofing agent is blended with a part of the molding material for molding and manufacturing a building member or the like, a molded article such as a building member or the like in which the termite-proofing agent is blended can be obtained.
Specifically, at the time of extrusion molding of the foamed resin, a granular ant preventive agent is mixed with the foamable resin beads as the molding material, or a granular ant preventive agent is added to the melt-kneaded resin in the extruder. Can be. Of course, the present invention can be applied to ordinary resin molding that is not a foamed resin, and can also be applied to in-mold molding and injection molding other than extrusion molding.
防蟻剤を塗料に配合して防蟻塗料を製造することもできる。
何れの使用形態でも、それぞれの使用形態における安全基準や環境基準に合わせて、防蟻成分の含有量が適切に設定された防蟻剤を使用することができる。
An ant-proofing paint can also be produced by blending an ant-proofing agent into the paint.
In any of the usage forms, it is possible to use an ant control agent in which the content of the ant protection component is appropriately set in accordance with the safety standards and environmental standards in the respective usage forms.
本発明にかかる防蟻剤は、実際の防蟻機能を果たす防蟻成分が、無機材料の粉体に複合一体化された粒状物になっているので、防蟻機能を果たすのに必要なだけの比較的低濃度の防蟻成分が、防蟻剤全体に均一に分散された状態で存在することになる。
防蟻剤の個々の粒子に、防蟻成分が一定の割合で存在しているので、防蟻剤を使用したときに、場所によって防蟻成分が偏在するようなことがなくなる。輸送保管時に、粒径や粒形状による防蟻剤粉体の偏在が発生したとしても、全ての防蟻剤粉体で、同じ割合の防蟻成分が配合されているので、防蟻成分の偏在は発生しない。
その結果、防蟻成分の偏在による防蟻機能のバラツキがなくなり、防蟻機能の低い部分を白蟻に食い破られたり通過されたりする問題が解消できる。防蟻機能が低い部分を無くすために、防蟻成分を過剰に配合することをしなくてもよい。局部的に高濃度の場所ができて、安全性に問題が出ることもない。防蟻剤における防蟻成分の含有濃度を低く抑えても十分な防蟻機能を発揮させることができるので、取扱い中における安全性が高まり、厳重な管理も必要なくなり、使用し易いものとなる。
The termite-proofing agent according to the present invention is a granule in which the termite-proofing component that performs the actual termite-proofing function is combined and integrated with the powder of the inorganic material, so that it is only necessary to fulfill the termite-proofing function. This relatively low concentration of the ant preventive component is present in a state of being uniformly dispersed throughout the ant preventive agent.
Since the ant-preventive component is present in a certain ratio in the individual particles of the ant-repellent, when the ant-preventive agent is used, the ant-preventive component is not unevenly distributed depending on the location. Even if uneven distribution of the termite-preventive powder due to particle size or particle shape occurs during transportation and storage, all the termite-preventive powders contain the same proportion of the termite-preventive component, so the uneven distribution of the termite-preventive component Does not occur.
As a result, there is no variation in the ant protection function due to the uneven distribution of the ant protection component, and the problem that the part with a low ant protection function is eaten and passed by the white ants can be solved. In order to eliminate the portion having a low ant protection function, it is not necessary to add an excessive amount of the ant protection component. A highly concentrated area can be created locally, and there is no safety problem. Even if the concentration of the ant protection component in the ant protection agent is kept low, a sufficient ant protection function can be exhibited. Therefore, safety during handling is enhanced, strict management is not required, and it is easy to use.
特に、防蟻剤を配合した発泡樹脂の製造など、防蟻剤を取り扱う必要がある各種製造装置および製造作業において、装置内部に高濃度の防蟻成分が付着したままになったり、作業員が高濃度の防蟻成分と接触したりする問題が解消できる。作業の安全性が向上し、製造管理が容易になり、生産性の向上を図ることができる。 In particular, in various manufacturing equipment and manufacturing operations that require handling of an anti-anticide, such as the production of foamed resin containing an anti-anticide, a high-concentration anti-ant component remains attached inside the device, The problem of contact with a high concentration of ant protection component can be solved. Work safety is improved, manufacturing management is facilitated, and productivity can be improved.

〔防蟻剤の製造〕
＜実施例１＞
無機粉末１９６ｇと、防蟻成分４ｇとを、ボールミル（フリッチュ社製、遊星型ボールミル、容量５００ｃｃ）に投入して、粉砕混合した。具体的には、ボールミルに防蟻成分のみを投入し、回転数１５０ｒｐｍで１５分間、作動させた。その後、無機粉末を加え、回転数１５０ｒｐｍで３０分間、作動させた。
The result of having manufactured an anti-anticide concretely and evaluating the performance is demonstrated.
[Materials used]
Anti-ant ingredient: Imidacloprid. Powder with an average particle size of 20 μm.
When taking a photo to be described later, in order to visually distinguish it from inorganic powder, it was colored orange with a colorant Chemicolor E (manufactured by Chemiholz). It is not necessary to color when using an actual ant inhibitor.
Inorganic material: kaolin clay. Powder with an average particle size of 40 μm.
[Manufacture of ant-proofing agents]
<Example 1>
196 g of the inorganic powder and 4 g of the ant-proofing component were put into a ball mill (Fritsch, planetary ball mill, capacity 500 cc) and pulverized and mixed. Specifically, only the ant-proof component was charged into the ball mill and operated for 15 minutes at a rotation speed of 150 rpm. Then, inorganic powder was added and it was made to operate for 30 minutes at 150 rpm.
＜比較例１＞
比較例として、同じ材料を同じ装置で、処理条件を変えて、混合処理した。処理条件は、ボールミルに無機粉末と防蟻成分とを同時に投入し、回転数５０ｒｐｍで１５分間、作動させた。
〔防蟻剤の構造と特性〕
＜実施例１＞
得られた防蟻剤を、顕微鏡で観察したところ、白色を呈する無機粉末の粒子の一部に、オレンジ色に着色された防蟻成分が、細い線状をなして一体的に複合化された状態になっていることが確認できた。図１は、防蟻剤を撮影した写真である。
<Comparative Example 1>
As a comparative example, the same material was mixed and processed with the same apparatus under different processing conditions. The treatment conditions were that the inorganic powder and the ant protection component were simultaneously charged into a ball mill and operated at a rotation speed of 50 rpm for 15 minutes.
[Structure and properties of ant-proofing agent]
<Example 1>
When the obtained ant-proofing agent was observed with a microscope, an orange-colored ant-proofing ingredient was integrally formed in a thin line shape on a part of white inorganic powder particles. It was confirmed that it was in a state. FIG. 1 is a photograph of an anti-anticide taken.
得られた防蟻剤の全体から、少量の防蟻剤を抜き出して、液体クロマトグラフィにより防蟻剤に含まれる防蟻成分イミダクロプリドの含有量を測定する試験を繰り返したが、防蟻成分の含有量は、毎回の試験でほぼ一定であった。一定量の防蟻剤に一定時間の振動を加えたあとで、同様の試験を行なったが、場所による防蟻成分含有量のバラツキは生じなかった。
＜比較例１＞
比較例１で得られた防蟻剤についても、顕微鏡観察を行ったところ、白色の無機粉末と、オレンジ色の防蟻成分とがバラバラに分かれた独立した粒塊になって存在していることが認められた。図２は、防蟻剤を撮影した写真である。
A small amount of the termite-proofing agent was extracted from the whole of the obtained termite-proofing agent, and the test for measuring the content of the termite-proofing component imidacloprid contained in the termite-proofing agent by liquid chromatography was repeated. Was almost constant in each test. A similar test was conducted after applying a certain amount of vibration to a fixed amount of the termite-proofing agent, but there was no variation in the content of the termite-proofing component depending on the location.
<Comparative Example 1>
As for the termite-proofing agent obtained in Comparative Example 1, when microscopic observation was performed, the white inorganic powder and the orange-colored termite-preventing component existed as separate agglomerates separated into pieces. Was recognized. FIG. 2 is a photograph of an anti-anticide taken.
実施例１と同様に、防蟻成分の含有量を測定する試験を繰り返したところ、測定毎に防蟻成分の含有量が大きく変動していた。一定量の防蟻剤に一定時間の振動を加えると、防蟻成分の層と無機材料の層とが、着色状態の違いで視覚的に区別できるほど、偏在が発生した。
〔防蟻剤の使用：発泡樹脂ボード〕
実施例１の防蟻剤を、押出法による防蟻発泡ポリスチレンボードの製造に供した。
通常の発泡ポリスチレンボード製造原料に、実施例１の防蟻剤を所定の含有量になるように配合した状態で、押出成形装置による押出発泡成形を行った。防蟻剤は、通常のホッパ装置から、押出成形装置の原料溶融シリンダに供給して、原料とともに混練して全体に均一に分散させた。成形条件は、通常の発泡ポリスチレンボードの成形条件と同様であった。押出成形品を所定の寸法に裁断して、縦１８２ｃｍ×横９１ｃｍの矩形で厚み５ｃｍの防蟻発泡ポリスチレンボードを得た。
As in Example 1, when the test for measuring the content of the termite-preventing component was repeated, the content of the termite-preventing component varied greatly every measurement. When a certain amount of the termite-proofing agent was vibrated for a certain period of time, uneven distribution occurred so that the layer of the termite-preventing component and the layer of the inorganic material could be visually distinguished by the difference in the colored state.
[Use of ant-proofing agent: foamed resin board]
The ant-proofing agent of Example 1 was used for the production of an ant-proof foamed polystyrene board by an extrusion method.
Extrusion foam molding by an extrusion molding apparatus was performed in a state where the antifoaming agent of Example 1 was blended in a normal raw material for foamed polystyrene board so as to have a predetermined content. The termite-proofing agent was supplied from a normal hopper device to a raw material melting cylinder of an extrusion molding device, kneaded together with the raw material, and uniformly dispersed throughout. The molding conditions were the same as those for ordinary foamed polystyrene boards. The extruded product was cut into a predetermined size to obtain an ant-proof foamed polystyrene board having a rectangular shape of 182 cm in length and 91 cm in width and a thickness of 5 cm.
＜防蟻発泡ポリスチレンボードの特性＞
前項で得られた防蟻発泡ポリスチレンボードについて、その性能を評価する試験を行なった。実施例２−１は、実施例１の防蟻剤を０．１％含有し、実施例２−２は、実施例１の防蟻剤を０．２％含有している。
(1) 均一分散性
防蟻発泡ポリスチレンボードの長さ方向で両端近くおよび中央の３個所からサンプルを採取し、液体クロマトグラフィーで、防蟻成分であるイミダクロプリドの含有量を測定した。常法により比重も測定した。３個所の測定値の平均値を算出した。その結果を表１に示す。
<Characteristics of ant-proof polystyrene board>
A test for evaluating the performance of the ant-proof foamed polystyrene board obtained in the previous section was conducted. Example 2-1 contains 0.1% of the termite-proofing agent of Example 1, and Example 2-2 contains 0.2% of the termite-proofing agent of Example 1.
(1) Uniform dispersibility Samples were collected from three places near the center and at both ends in the length direction of the ant-proof foamed polystyrene board, and the content of imidacloprid, an ant-proof component, was measured by liquid chromatography. Specific gravity was also measured by a conventional method. The average value of the measured values at three locations was calculated. The results are shown in Table 1.
上記試験の結果、実施例２−１、２−２の何れも、ボードの全体で、防蟻成分の極端な偏りはなく、防蟻成分が均一に存在していることが判る。
(2) 防蟻性能
防蟻発泡ポリスチレンボードに対して、（社）日本木材保存協会規格第１１号に規定される防蟻室内試験に準じた試験を行った。その際に行う耐候試験は、ＪＩＳ−Ｋ１５７１「木材防腐剤の性能基準及び試験方法」に規定される耐候試験処理に準じて実施した。
耐候試験：試験体容積の１０倍量の水を加え、試験体を浮かび上がらせないように水面下に沈める。マグネチックスターラーを用い、温度２５±３℃で回転子を毎分４００〜５００回転させ、８時間撹拌して容脱させたあと、直ちに軽く試験体の表面の水切りを行った。次に、温度６０±２℃の乾燥器中に１６時間静置して揮発分を揮発させた。以上の操作を１０回繰り返した。
As a result of the above test, it can be seen that in all of Examples 2-1 and 2-2, there is no extreme bias of the ant-preventive component and the ant-preventive component is present uniformly throughout the board.
(2) Ant-proof performance The test according to the ant-proof room test prescribed | regulated to Japan Wood Preservation Society Standard No. 11 was performed with respect to the ant-proof foamed polystyrene board. The weathering test conducted at that time was carried out according to the weathering test treatment prescribed in JIS-K1571 “Performance standards and test methods for wood preservatives”.
Weather resistance test: Add water 10 times the volume of the specimen, and submerge the specimen below the surface of the water so as not to float. Using a magnetic stirrer, the rotor was rotated at 400 to 500 revolutions per minute at a temperature of 25 ± 3 ° C., stirred for 8 hours, and immediately drained. Next, the volatile matter was volatilized by standing in a drier at a temperature of 60 ± 2 ° C. for 16 hours. The above operation was repeated 10 times.
耐候試験を経た試験体に、防蟻室内試験を実施した。その結果を表２に示す。
An ant proof room test was carried out on the test specimen that had undergone the weather resistance test. The results are shown in Table 2.
上記試験の結果、各実施例の防蟻発泡ポリスチレンボードは、建築物の床下断熱材などに使用した場合に、実用的に十分な防蟻性能を発揮できることが確認された。 As a result of the above test, it was confirmed that the ant-proof foamed polystyrene board of each example can exhibit practically sufficient ant-proof performance when used as an underfloor heat insulating material of a building.
本発明の防蟻剤は、例えば、合成樹脂に配合されて、建築物の基礎構造に貼り付けて使用される防蟻発泡ボードや防蟻樹脂成形品を製造するのに利用できる。 The termite-proofing agent of the present invention can be used, for example, to produce an termite-proof foam board or an termite-resin-molded product that is blended in a synthetic resin and used by being attached to the basic structure of a building.
