Description
本発明は、害虫を忌避する効果（以下、「害虫忌避効果」という）を有する害虫忌避剤を含有し、害虫忌避成分を除放可能な害虫忌避組成物及びこれを含有した害虫忌避部材に関する。 The present invention relates to a pest repellent composition that contains a pest repellent having an effect of repelling pests (hereinafter referred to as “pest repellent effect”) and can release a pest repellent component, and a pest repellent member containing the same.
従来から、例えば、ゴキブリ、蟻、クモ、ムカデ等の昆虫等や、ネズミ等の小動物等（以下、このような昆虫や小動物等を総称して「害虫」と記す）が、建物や各種機器等、様々な対象物内に侵入することを防止する害虫忌避部材が紹介されている。このような害虫忌避部材として、例えば、害虫忌避除成分が含有された樹脂から構成され、害虫から保護すべき対象物に取付けることにより、害虫忌避部材から徐々に放出される害虫忌避成分の効果によって、前記対象物を害虫から保護するものが紹介されている。（例えば、特許文献１参照）。 Conventionally, for example, insects such as cockroaches, ants, spiders, and centipedes, and small animals such as mice (hereinafter, such insects and small animals are collectively referred to as “pests”) such as buildings and various devices. Insect repellent members that prevent entry into various objects have been introduced. As such a pest repellent member, for example, it is composed of a resin containing a pest repellent component and is attached to an object to be protected from the pest, whereby the effect of the pest repellent component gradually released from the pest repellent member Protecting the object from pests has been introduced. (For example, refer to Patent Document 1).
このような害虫忌避部材に使用されている害虫忌避組成物として、例えば、（Ａ）ポリアミド樹脂、ポリアセタール樹脂より選ばれる少なくとも１種の樹脂、（Ｂ）スルホンアミド誘導体、スルホン酸エステル誘導体、リン酸エステル誘導体、ホスファゼン誘導体、カルボン酸アミド誘導体、カルボン酸エステル誘導体より選ばれる少なくとも１種の化合物、及び（Ｃ）小動物防除性を有する薬剤を含有する樹脂組成物が紹介されている。（例えば、特許文献２参照）。 Examples of the pest repellent composition used in such a pest repellent member include, for example, (A) at least one resin selected from polyamide resins and polyacetal resins, (B) sulfonamide derivatives, sulfonic acid ester derivatives, phosphoric acid A resin composition containing at least one compound selected from an ester derivative, a phosphazene derivative, a carboxylic acid amide derivative, and a carboxylic acid ester derivative, and (C) a drug having small animal control properties has been introduced. (For example, refer to Patent Document 2).
また、近年では、害虫忌避部材に使用されている種々の害虫忌避剤の中でも、人間等に対して安全性が高く、自然に帰しやすく、環境に優しいことから、天然物から抽出されるヒノキチオール等を有効成分とする薬剤が好んで使用されている。このような害虫忌避組成物として、例えば、水分及び嫌気性バクテリアの存在下で崩壊する生分解性樹脂に、ヒノキチオール、テルペン類、チモールを含有するハーブよりなる群から選ばれた天然由来の動物忌避剤、及び界面活性剤を混練したものが紹介されている。（例えば、特許文献３参照）。
天然由来の害虫忌避剤は、害虫忌避効果を有することに加え、低毒性で広い抗菌スペクトルをもっており、環境に優しい害虫忌避部材として期待されている。この中で、ヒノキチオールを害虫忌避剤として使用する方法としては、例えば、ヒノキチオールを溶媒に分散させた溶液を、所望領域に塗布する方法や、ヒノキチオールを樹脂中に分散・担持させた害虫忌避組成物を任意の形状に加工して害虫忌避部材とし、この害虫忌避部材を所望の場所に設置する等の方法がある。 Naturally derived pest repellents have a pest repellent effect, have low toxicity and a broad antibacterial spectrum, and are expected as environmentally friendly pest repellent members. Among these, as a method of using hinokitiol as a pest repellent, for example, a method in which a solution in which hinokitiol is dispersed in a solvent is applied to a desired region, or a pest repellent composition in which hinokitiol is dispersed and supported in a resin The pest repellent member is processed into an arbitrary shape, and the pest repellent member is installed at a desired location.
しかしながら、ヒノキチオールを溶媒に分散させた溶液を塗布する方法は、ヒノキチオールが昇華、拡散したり、紫外線によって分解しやすく、害虫忌避効果が短時間しか持続せず、定期的に繰り返し塗布する必要がある。また、ヒノキチオールを樹脂中に分散・担持させた害虫忌避組成物は、ヒノキチオールの昇華や紫外線による分解を軽減することはできるが、ヒノキチオールの担持効果が低く、害虫忌避効果を長期に亘って維持することが困難である。 However, the method of applying a solution in which hinokitiol is dispersed in a solvent, the hinokitiol is easily sublimated and diffused, is easily decomposed by ultraviolet rays, has a pest repellent effect only for a short time, and needs to be applied periodically and repeatedly. . In addition, the insect repellent composition in which hinokitiol is dispersed and supported in the resin can reduce the degradation of hinokitiol by sublimation and ultraviolet rays, but the effect of supporting hinokitiol is low and the insect repellent effect is maintained over a long period of time. Is difficult.
また、前述した特許文献３に記載された害虫忌避組成物は、生分解性樹脂にヒノキチオールを混練したものであり、樹脂中に分散されたヒノキチオールが当該樹脂内部から２〜３ヶ月程度で完全に除放してしまう。さらに、生分解性樹脂が完全に生分解してしまうまでは、害虫忌避効果を持続させることができる。ここで、忌避すべき害虫は、多くの場合、水分を好む或いは高湿度を好むため、害虫忌避組成物は、通常、水分が存在する高湿度な場所に置かれることが多い。しかしながら、特許文献３に記載された害虫忌避組成物に使用されている生分解性樹脂は、水分が存在すると生分解しやすいため、水分が存在する高湿度な場所では害虫忌避効果を長期に亘って維持することが困難である。 Moreover, the insect repellent composition described in Patent Document 3 described above is obtained by kneading hinokitiol in a biodegradable resin, and the hinokitiol dispersed in the resin is completely removed within about 2 to 3 months from the inside of the resin. I will be released. Further, the insect repellent effect can be maintained until the biodegradable resin is completely biodegraded. Here, since the pests to be repelled often prefer moisture or high humidity, the pest repellent composition is usually placed in a high-humidity place where moisture exists. However, since the biodegradable resin used in the pest repellent composition described in Patent Document 3 is easily biodegradable in the presence of moisture, the pest repellent effect is maintained over a long period of time in a high-humidity location where moisture exists. Difficult to maintain.
本発明は、このような事情に鑑みなされたものであり、害虫忌避剤として天然由来成分を用いた害虫忌避組成物であり、且つ常温常湿の場所は勿論のこと、高温多湿の場所であっても、害虫忌避成分を除放することができ、長期間に亘って害虫忌避効果を発揮することが可能な害虫忌避組成物を提供することを目的とする。 The present invention has been made in view of such circumstances, and is a pest repellent composition using a naturally-derived component as a pest repellent, and is a place of high temperature and high humidity as well as a place of normal temperature and humidity. However, an object of the present invention is to provide a pest repellent composition capable of releasing a pest repellent component and capable of exerting a pest repellent effect over a long period of time.
この目的を達成するため本発明は、樹脂と、無機充填材と、天然由来成分の害虫忌避剤と、を含有し、前記無機充填材が有機物で被覆されたものであり、前記無機充填材の吸油量は、１０ｍｌ／１００ｇ以上、１２０ｍｌ／１００ｇ以下であり、前記無機充填材のｐＨは、ｐＨ４以上、ｐＨ１０以下であり、前記有機物は、ステアリン酸、オレイン酸、パルミチン酸、リノール酸、ラウリン酸、カプリル酸、ベヘニン酸、及びモンタン酸、または、その塩、そのエステル化合物、そのアマイド化合物；オクチルアルコール、デシルアルコール、ラウリルアルコール、ミリスチルアルコール、セチルアルコール、及びステアリルアルコール；ココナッツ油、大豆油、アマニ油、及びサフラワー油、よりなる群から選択される、害虫忌避組成物を提供するものである。
In order to achieve this object, the present invention comprises a resin, an inorganic filler, and a pest repellent that is a naturally derived component, and the inorganic filler is coated with an organic substance. Oil absorption is 10 ml / 100 g or more and 120 ml / 100 g or less, pH of the inorganic filler is pH 4 or more and
この構成を備えた害虫忌避組成物は、無機充填材が有機物で被覆されているため、当該無機充填材の表面が害虫忌避剤に接触することを防止することができる。ここで、天然由来成分の害虫忌避剤は、人間等に対して安全性が高く、自然に帰しやすく、環境に優しい反面、分解しやすいため、無機充填材に接触すると化学構造が変化しやすく、害虫忌避効果が低下しやすいことが知られている。本発明では、無機充填材を有機物で被覆することで、害虫忌避剤が無機充填材に接触することを防止でき、化学構造が変化することを抑制することができる。さらにまた、害虫忌避剤は、有機物で被覆された無機充填材に確実に担持され、害虫に対して効果を有する程度で害虫忌避剤が除放される。したがって、常温常湿の場所は勿論のこと、高温多湿の場所であっても、害虫忌避成分を維持すると共に除放することができ、長期間に亘って害虫忌避効果を発揮することができる。 The pest repellent composition having this configuration can prevent the surface of the inorganic filler from coming into contact with the pest repellent because the inorganic filler is coated with an organic substance. Here, the pest repellent, a naturally-derived component, is highly safe for humans and the like, is easy to attribute naturally, is friendly to the environment, but is easy to decompose, so its chemical structure is likely to change when it comes into contact with inorganic fillers, It is known that the pest repellent effect tends to decrease. In this invention, it can prevent that a pest repellent contacts an inorganic filler by coat | covering an inorganic filler with organic substance, and can suppress that a chemical structure changes. Furthermore, the pest repellent is reliably supported on an inorganic filler coated with an organic substance, and the pest repellent is released to the extent that it has an effect on the pest. Therefore, the pest repellent component can be maintained and released even in a place of high temperature and humidity as well as a place of normal temperature and humidity, and a pest repellent effect can be exhibited over a long period of time.
また、本発明にかかる害虫忌避組成物に含有される無機充填材は、吸油量が１０ｍｌ／１００ｇ以上、１２０ｍｌ／１００ｇ以下であることが好ましい。無機充填材の吸油量が１０ｍｌ／１００ｇ未満であると、害虫忌避剤を好適に担持する効果を得ることが困難である。一方、無機充填材の吸油量が１２０ｍｌ／１００ｇを超えると、害虫忌避成分が放出されることを妨げる虞がある。 In addition, the inorganic filler contained in the pest repellent composition according to the present invention preferably has an oil absorption of 10 ml / 100 g or more and 120 ml / 100 g or less. When the oil absorption amount of the inorganic filler is less than 10 ml / 100 g, it is difficult to obtain the effect of suitably carrying the pest repellent. On the other hand, when the oil absorption amount of the inorganic filler exceeds 120 ml / 100 g, there is a possibility that the release of the pest repellent component is hindered.
そしてまた、本発明にかかる害虫忌避組成物に含有される無機充填材は、ｐＨ４以上、ｐＨ１０以下であることが好ましい。アルカリ度、酸性度が強いと、害虫忌避剤が反応して害虫忌避効果が低下しやすい。 The inorganic filler contained in the pest repellent composition according to the present invention preferably has a pH of 4 or more and a pH of 10 or less. If the alkalinity and acidity are strong, the pest repellent reacts and the pest repellent effect tends to be reduced.
