In addition to the antibacterial and antifungal effects, the present invention has a high control effect on termites and is toxic to living bodies such as human bodies. It is intended to provide a termite control agent that has a high termite control effect over a long period of time, has a termite control action that maintains safety in the living environment, and can effectively achieve the killing effect within a short period of time. To do.
シロアリが人類の生活環境に対し害をなすことは明らかであり、シロアリを防除することについては従来から種々に検討が重ねられてきたが、今日においても必ずしも安定、且つ的確な手法が確立されるに至っていない。すなわち、シロアリ防除剤としては、有機リン酸系のものや、ビレスロイド系や有機塩素系のものがよく採用されており、家屋その他の建築物における床下のシロアリの進出、ないし通過する可能性の高い個所に散布し、あるいは噴霧または分散することが一般的であって、そのための機器、手法や部材その他については各種の提案が重ねられている。しかしながら、これら有機系薬剤はシックハウスの原因物質の１つとして大きな問題となっている。 It is clear that termites are harmful to the human living environment, and various studies have been conducted on the control of termites, but even today, stable and accurate methods are always established. It has not reached. That is, as the termite control agent, organophosphate-based, bilesloid-based or organochlorine-based ones are often adopted, and there is a high possibility that termites will enter or pass under the floor in houses and other buildings. It is common to spray, disperse, or disperse in a part, and various proposals are repeated about the apparatus, method, member, etc. for it. However, these organic drugs are a major problem as one of the causative substances of sick houses.
従来、コレマナイトを用いるシロアリ防除剤として特開平２０００−２６２１８号公報に開示されたものが公知である。また、コレマナイト粒子を焼成することにより抗菌・抗カビ効果を有することは、特開２００２−２０２１０号公報に開示されて公知である。
前記特許文献１で開示されたものは、水に対し難溶性を有するホウ素含有鉱物コレマナイトを用いることにより、シロアリなどの防除に関して、成分が溶出し難いことから、土壌中にも溶出し難く、長期の防除効果を期待することができる。更に、コレマナイトは揮発もしないことから、シックハウスの問題も起こり難く、施工上の安全性も確保できる。しかしながら、抗菌・抗カビ効果も持たないことから、木材の不朽菌に対しては、効果が期待できない。 The one disclosed in Patent Document 1 uses a boron-containing mineral colemanite that is sparingly soluble in water, so that it is difficult for components to elute in terms of control of termites and the like, so that it is difficult to elute in soil, and long term. Can be expected to have a control effect. Furthermore, since colemanite does not volatilize, the problem of sick house hardly occurs, and construction safety can be secured. However, since it does not have antibacterial and antifungal effects, no effect can be expected against the immortal fungi of wood.
前記特許文献２で開示された主眼は、ホウ素およびアルカリ土類金属複酸化物の化学組成式ａＭＯ・ｂＢ２Ｏ３(Ｍ：アルカリ土類金属、ａ／ｂ：０．５〜３の数値)で表わされる物質、または、ホウ素およびアルカリ土類金属から構成される鉱石を酸化、中性または還元雰囲気中で焼成することにより生成された物質、あるいは、ホウ素塩とアルカリ土類塩、またはそれらを主成分とする物質を混合して加熱することにより生成された物質（以下、前記３つの物質を「抗菌・抗カビ物質」と略称する）が抗菌・抗カビ効果を有しているということであるが、前記各物質がシロアリ防除剤として機能することについては、これまで全く検討されていなかった。 The main point disclosed in Patent Document 2 is the chemical composition formula aMO · bB 2 O 3 of boron and an alkaline earth metal double oxide (M: alkaline earth metal, a / b: numerical value of 0.5 to 3). Or a substance produced by firing an ore composed of boron and an alkaline earth metal in an oxidizing, neutral or reducing atmosphere, or a boron salt and an alkaline earth salt, or A substance produced by mixing and heating a substance as a main component (hereinafter, the three substances are abbreviated as “antibacterial / antifungal substance”) has an antibacterial / antifungal effect. However, it has not been studied so far that each of the above substances functions as a termite control agent.
本発明は、抗菌・抗カビ効果を有するものとして公知となっている前記抗菌・抗カビ物質をシロアリの防除剤として用いることにより、木材をシロアリから防除するだけではなく、木材の腐朽菌に対しても有効なことから、木材腐朽防除の付加価値を有し、しかも効果の長期持続性を得しめ、然もシックハウスや施工上の安全性を確保することができるシロアリ防除剤を提供しようとする点にある。 The present invention uses the antibacterial and antifungal substances known as having antibacterial and antifungal effects as termite control agents, thereby not only controlling wood from termites but also against wood decaying fungi. Because it is effective, it tries to provide a termite control agent that has the added value of wood decay control and has long-term sustainability of the effect, yet can secure safety in sick houses and construction. In the point.
本発明は、前記抗菌・抗カビ効果を有する抗菌・抗カビ物質を、シロアリ防除剤とすることを最も主要な特徴とする。 The main feature of the present invention is that the antibacterial / antifungal substance having the antibacterial / antifungal effect is a termite control agent.
本発明のシロアリ防除剤は、抗菌・抗カビ効果を有する外に、シロアリの防除に関し、高い殺蟻効果を短期間内に発揮せしめると共に、人体に対する安全性が高く、しかも防除効果を長期に亘って維持せしめ、更にはその製造調整が簡易であるなどの効果を有する。 In addition to having antibacterial and antifungal effects, the termite control agent of the present invention has a high ant killing effect within a short period of time, and is highly safe for the human body and has a long-term control effect. In addition, it has effects such as easy manufacturing adjustment.
抗菌・抗カビ効果を有する前記抗菌・抗カビ物質を、シロアリ防除剤とすることにより、人体に害を与えることなく殺蟻効果を発揮した。 By using the above-mentioned antibacterial / antifungal substance having an antibacterial / antifungal effect as a termite control agent, the anticide effect was exerted without harming the human body.
本発明の実施例につき詳細に説明する。本発明者は、前記特許文献２で開示されているように、抗菌・抗カビ物質が抗菌および抗カビ効果を有することを立証し、抗菌および抗カビ剤並びにその製造方法を発明した。そして更に、本発明者は、前記抗菌・抗カビ効果を有する抗菌・抗カビ物質が、シロアリに対する殺蟻性においても有用であることを確認し、本発明をなしたものである。 Examples of the present invention will be described in detail. As disclosed in Patent Document 2, the inventor has proved that antibacterial and antifungal substances have antibacterial and antifungal effects, and invented an antibacterial and antifungal agent and a method for producing the same. Furthermore, the present inventor has confirmed that the antibacterial / antifungal substance having the antibacterial / antifungal effect is also useful in termicidal activity against termites, and has made the present invention.
すなわち、前記抗菌・抗カビ物質中、特にホウ素系天然鉱物であるコレマナイトＣａ２Ｂ６Ｏ１１・５Ｈ２Ｏについて仔細に検討したところ、５０μｍ〜３μｍ程度のコレマナイト素材を３５０℃以上、好ましくは５００℃で空気または二酸化炭素雰囲気中で１時間焼成することにより、（１）式に示すような反応式となり、ＣａＯ・２Ｂ２Ｏ３が生成される。 That is, the antifungal substance, was examined in circumstance for colemanite Ca 2 B 6 O 11 · 5H 2 O is particularly boron-based natural mineral, the colemanite material about 50μm~3μm 350 ℃ or higher, preferably 500 By calcination for 1 hour in air or carbon dioxide atmosphere at ° C., the reaction formula shown in formula (1) is obtained, and CaO.2B 2 O 3 is generated.
そこで、焼成して得られたコレマナイト焼成品と、焼成処理のなされない比較品とを準備し、これらのコレマナイト焼成品と比較品について、それぞれ日本木材保存協会第１３号の室内試験に準じた試験を行った結果を示すと、表１の通りであった。 Therefore, a fired colemanite product obtained by firing and a comparative product not subjected to firing treatment were prepared, and these fired products and comparative products were tested in accordance with the laboratory tests of the Japan Wood Preservation Association No. 13 respectively. Table 1 shows the result of the measurement.
すなわち、コレマナイト焼成品は、比較品（未焼成）に比しいずれも４分の１以下の短期間内に全部のシロアリが死滅することが確認され、有効な殺蟻性を有することが確認された。 That is, it was confirmed that all the termites were killed within a short period of one quarter or less compared to the comparative product (unfired), and the colemanite fired product was confirmed to have an effective anticide. It was.
すなわち、前記コレマナイト焼成品は、従来採用されている有機リン酸系や、ビレスロイド系、あるいは有機塩素系のものにおけるような揮発成分が、作業者や居住者に与えるような悪影響を実質的有効に回避せしめることができる。 That is, the colemanite fired product substantially effectively exerts an adverse effect on the worker or occupant caused by volatile components such as those conventionally used in organic phosphates, bilesroids, or organochlorines. It can be avoided.
前記表１においては、コレマナイト焼成品のみしか試験を行っていないが、該コレマナイト焼成品以外のホウ素およびアルカリ土類金属複酸化物の化学組成式ａＭＯ・ｂＢ２Ｏ３(Ｍ：アルカリ土類金属、ａ／ｂ：０．５〜３の数値)で表わされる物質、または、ホウ素およびアルカリ土類金属から構成される鉱石を酸化、中性または還元雰囲気中で焼成することにより生成された物質、あるいは、ホウ素塩とアルカリ土類塩、またはそれらを主成分とする物質を混合して加熱することにより生成された物質も焼成コレマナイトと同様、抗菌・抗カビ効果を有すると共に、焼成コレマナイトと同様、ホウ素およびアルカリ土類金属であるので、殺蟻性を有していることが類推できる。 In Table 1, only the colemanite fired product was tested, but the chemical composition formula of a boron and alkaline earth metal double oxide other than the colemanite fired product aMO · bB 2 O 3 (M: alkaline earth metal) A / b: a numerical value of 0.5 to 3), or a substance produced by firing an ore composed of boron and an alkaline earth metal in an oxidizing, neutral or reducing atmosphere, Alternatively, a boron salt and an alkaline earth salt, or a substance produced by mixing and heating a substance containing them as a main component also has an antibacterial / antifungal effect, similar to calcined colemanite, Since boron and alkaline earth metals, it can be inferred that they have anticide properties.
そして、本発明によるシロアリ防除剤は、粉体または粒材とすることにより、床下などにおける撒布を容易化し、所要の位置に対し、的確に撒布、展開せしめ、安定した防虫工法を実現せしめることができると共に、抗菌・抗カビ効果を有しているので、柱・床材等の菌・カビの発生をも合わせ阻止することができるのである。 The termite control agent according to the present invention makes it easy to spread under the floor or the like by using a powder or a granule, and can accurately spread and deploy the desired position to achieve a stable insect control method. In addition to being able to have antibacterial and antifungal effects, it can also prevent the generation of fungi and molds such as pillars and flooring.
更に、本発明によるシロアリ防除剤を塗料に混入し、木材などに塗布すること、あるいは微粉砕した前記防除剤を溶液に分散させ、木材などに含浸させることにより、木材等をシロアリおよび木材腐朽から防除することができる。 Furthermore, the termite control agent according to the present invention is mixed in a paint and applied to wood or the like, or the finely pulverized control agent is dispersed in a solution and impregnated in wood or the like, so that the wood or the like is prevented from termites and wood decay. It can be controlled.
なお、珪砂を増量材として併用することによって施工性を良好とし、有効、且つ適切な撒布状態を的確に形成せしめる。前記珪砂を増量材として使用した実験結果は表１に記載されており、珪砂の量が少ないほど殺蟻性を有している。
In addition, by using silica sand as an extender, the workability is improved, and an effective and appropriate distribution state is accurately formed. The experimental results using the silica sand as an extender are listed in Table 1. The smaller the amount of silica sand, the more anticide.
