Description
本發明係關於即使燃燒後，亦持續殺蟲效果之持續性滅蚊線香。The present invention relates to a continuous mosquito-killing incense which has a continuous insecticidal effect even after burning.
作為驅除蚊等之飛翔害蟲的製品，廣泛使用有藉由煙燻，使殺蟲成分揮散在處理對象的空間之滅蚊線香。滅蚊線香係以配合人類的就寢時間，將一柱的燃燒時間設定在7～8小時左右，致燃盡為止使處理對象的空間所存在的害蟲擊倒或致死，進而從該空間，排除或忌避害蟲的方式進行作用。As a product for repelling flying insects such as mosquitoes, mosquito-killing incenses are widely used, which are smoked to disperse the insecticidal ingredients in the space of the object to be treated. The mosquito-killing incense is designed to match the bedtime of human beings. The burning time of a column is set at about 7-8 hours, so that the pests existing in the space of the treatment object will be knocked down or killed until the burn is exhausted, and then the space will be removed or killed. It acts in a way that avoids pests.
然而，近年來，於衛生環境的整備或住宅事情的變化，尤其是於都市部的大樓等，亦有住居的密閉化正進展中的情況，減少蚊等之害蟲從建物外侵入建物內的機會。因此，若於就寢前驅除房間有的蚊等，已不需要必定如以往之滅蚊線香，連續於就寢時間中，揮散殺蟲成分。由該狀況來看，目前為止，在長時間的連續使用已被認為是基本的滅蚊線香，提案有企圖嘗試燃燒時間的縮短。However, in recent years, due to the maintenance of sanitary environment and changes in residential matters, especially in the buildings of the City Department, there are also cases in which housing closures are in progress, reducing the chance of mosquitoes and other pests entering the building from outside the building. . Therefore, if you get rid of mosquitoes in the room before going to bed, it is no longer necessary to use the conventional mosquito-killing incense to evaporate insecticidal ingredients during bedtime. Judging from this situation, so far, long-term continuous use has been regarded as a basic mosquito-killing incense, and there are proposals to try to shorten the burning time.
例如，有於殺蟲成分使用美特寧、丙氟菊酯、拜富靈等之常溫揮散性除蟲菊酯之滅蚊線香(例如參照專利文獻1)。專利文獻1之滅蚊線香由於即使燃燒後，殺蟲成分經過長時間，亦殘存於空氣中，故即使縮短燃燒時間，亦長時間持續殺蟲效果。 [先前技術文獻] [專利文獻]For example, there are mosquito-killing incenses that use room temperature volatile pyrethrins such as methelthrin, profluthrin, and Bayfulin for insecticidal ingredients (for example, refer to Patent Document 1). In the mosquito-killing incense of Patent Document 1, since the insecticidal components remain in the air for a long time even after burning, the insecticidal effect continues for a long time even if the burning time is shortened. [Prior Technical Literature] [Patent Literature]
[專利文獻1]日本特開2011-12056號公報[Patent Document 1] JP 2011-12056 A
[發明欲解決之課題][The problem to be solved by the invention]
然而，在滅蚊線香，正尋求減低起因於殺蟲成分或香料成分，進而減低煙霧等之臭味或刺激的製品。然而，專利文獻1已將邊縮短燃燒時間邊使必要量之殺蟲成分揮散作為主要重點，針對燃燒時之刺激的減低尚殘留研究的餘地。However, in anti-mosquito coils, products are being sought to reduce the insecticidal ingredients or fragrance ingredients, thereby reducing the smell or irritation of smoke. However, Patent Document 1 has focused on reducing the burning time while evaporating the necessary amount of insecticidal components, and there is still room for research on reducing the irritation during burning.
本發明係鑑於上述問題點而完成者，以提供一種邊減低燃燒時之刺激，邊即使短時間的燃燒，亦可長時間持續殺蟲效果的持續性滅蚊線香作為目的。 [用以解決課題之手段]The present invention has been completed in view of the above-mentioned problems, and aims to provide a continuous mosquito-killing incense which can keep the insecticidal effect for a long time even after burning for a short time while reducing the irritation during burning. [Means to solve the problem]
有關用以解決上述課題之本發明之持續性滅蚊線香的特徵構成，其係即使在燃燒後，亦持續殺蟲效果之持續性滅蚊線香，其特徵為含有： 選自由美特寧、丙氟菊酯及拜富靈所成之群組中之至少一種的殺蟲成分、與碘吸附能為200mg/g以下之碳化物基材。Regarding the characteristic structure of the continuous mosquito-killing incense of the present invention for solving the above-mentioned problems, it is a continuous mosquito-killing incense that has a continuous insecticidal effect even after burning, and it is characterized by containing: An insecticidal ingredient selected from at least one of the group consisting of Metenine, Profluthrin, and Bayefulin, and a carbide substrate with an iodine adsorption energy of 200 mg/g or less.
根據本構成之持續性滅蚊線香，除了含有選自由美特寧、丙氟菊酯及拜富靈所成之群組中之至少一種的殺蟲成分，並藉由含有碘吸附能為200mg/g以下之碳化物基材，即使燃燒後，殺蟲成分經過長時間，亦殘存於空氣中，故變成可長時間持續殺蟲效果。又，碘吸附能為200mg/g以下之碳化物基材，可一邊防止過剩分解殺蟲成分，而減低殺蟲效果，一邊減低起因於燃燒時之煙霧等的臭味或刺激。The continuous mosquito-killing incense according to this composition contains at least one insecticidal ingredient selected from the group consisting of methelthrin, profluthrin and befulin, and has an adsorption energy of 200mg/ by containing iodine. For carbide substrates below g, the insecticidal components remain in the air even after burning for a long time, so the insecticidal effect can be sustained for a long time. In addition, a carbide substrate with an iodine adsorption capacity of 200 mg/g or less can prevent excessive decomposition of insecticidal components and reduce the insecticidal effect, while reducing the odor or irritation caused by smoke during combustion.
在有關本發明之持續性滅蚊線香，較佳為 將在燃燒時之前述殺蟲成分每一單位時間之揮散量設定在0.05～15mg/分鐘。Regarding the continuous mosquito-killing incense of the present invention, preferably The volatilization amount of the aforementioned insecticidal ingredients per unit time during combustion is set at 0.05-15 mg/min.
根據本構成之持續性滅蚊線香，藉由殺蟲成分每一單位時間之揮散量為上述的範圍，即使短時間的燃燒，亦可使充分量之殺蟲成分揮散在空氣中。According to the continuous mosquito-killing incense of the present composition, since the volatilization amount of the insecticidal component per unit time is within the above range, even if it is burned for a short period of time, a sufficient amount of the insecticidal component can be dispersed in the air.
在有關本發明之持續性滅蚊線香，較佳為 將燃燒時間設定在30分鐘以內。Regarding the continuous mosquito-killing incense of the present invention, preferably Set the burning time within 30 minutes.
根據本構成之持續性滅蚊線香，藉由將燃燒時間設定在30分鐘以內，僅於就寢前燃燒線香，即可防除蚊類，成為易於使用的製品。According to the continuous mosquito-killing incense of this structure, by setting the burning time within 30 minutes, the incense can be burned just before bedtime to prevent mosquitoes and become an easy-to-use product.
在有關本發明之持續性滅蚊線香，較佳為 將燃燒後之殺蟲效果的持續時間設定在8小時以上。Regarding the continuous mosquito-killing incense of the present invention, preferably Set the duration of the insecticidal effect after burning to more than 8 hours.
根據本構成之持續性滅蚊線香，藉由將燃燒後之殺蟲效果的持續時間設定在8小時以上，於夜間使用時，人類於一整夜不會被蚊類咬，可舒服地睡覺。又，將燃燒時間設定在30分鐘以內，若將每個燃燒後之殺蟲效果的持續時間設定在8小時，由於人們要入睡時，持續性滅蚊線香的火消滅，故不必擔心火災，即使夜間亦可安心地使用。According to the continuous mosquito-killing incense stick of the present composition, by setting the duration of the burning insecticidal effect at more than 8 hours, when used at night, humans will not be bitten by mosquitoes throughout the night and can sleep comfortably. Also, set the burning time within 30 minutes. If the duration of each burned insecticidal effect is set at 8 hours, since people are going to sleep, the fire of the mosquito-killing incense will be extinguished continuously, so there is no need to worry about the fire. It can be used safely at night.
在有關本發明之持續性滅蚊線香，較佳為

以下，針對本發明之持續性滅蚊線香進行說明。惟，本發明並非被限定於以下所說明之實施形態所記載的構成。Hereinafter, the continuous mosquito-killing coil of the present invention will be described. However, the present invention is not limited to the configuration described in the embodiment described below.
〔持續性滅蚊線香〕 本發明之持續性滅蚊線香係含有殺蟲成分、與碳化物基材者，例如，藉由於含有殺蟲成分及碳化物基材之混合粉，加入適量之水並進行捏合，並將此藉由擠出機及沖孔機等成型後，並進行自然乾燥或加熱乾燥而獲得。於混合粉，作為其他基材，可摻合助燃劑、增量劑及黏結劑等。尚，殺蟲成分未直接摻合在混合粉，以於成型後，噴灑或是塗佈包含殺蟲成分等之液劑的方式進行亦無妨。持續性滅蚊線香的尺寸較佳為設定在全長100mm以下、厚度7mm以下、重量5g以下，更佳為設定在全長20mm以上90mm以下、厚度2mm以上5mm以下、重量0.2g以上3g以下。作為持續性滅蚊線香的形狀，雖可因應使用目的適當選擇棒狀、漩渦狀、錐狀、板狀等，但較佳為棒狀、漩渦狀、板狀。〔Continuous mosquito-killing incense stick〕 The continuous mosquito-killing incense of the present invention contains insecticidal ingredients and a carbide base material. For example, by adding an appropriate amount of water and kneading the mixed powder due to the insecticidal ingredient and the carbide base material, and this It is obtained by molding by an extruder, punching machine, etc., and then performing natural drying or heating and drying. Used in mixed powder, as other base materials, it can be blended with combustion aids, extenders and binders. Still, the insecticidal ingredient is not directly blended into the mixed powder, and it is OK to spray or apply a liquid containing the insecticidal ingredient or the like after molding. The size of the continuous mosquito-killing coil is preferably set to a total length of 100 mm or less, a thickness of 7 mm or less, and a weight of 5 g or less, more preferably set to a total length of 20 mm or more and 90 mm or less, a thickness of 2 mm or more and 5 mm or less, and a weight of 0.2 g or more and 3 g or less. As the shape of the continuous mosquito-killing coil, a rod shape, a spiral shape, a cone shape, a plate shape, etc. can be appropriately selected according to the purpose of use, but a rod shape, a spiral shape, or a plate shape is preferable.
作為殺蟲成分，係使用具有常溫揮散性之除蟲菊酯系殺蟲成分的美特寧、丙氟菊酯或拜富靈。於此等之除蟲菊酯系殺蟲成分的化學構造中，依據不齊碳或雙鍵，存在光學同分異構物或幾何同分異構物時，任何同分異構物皆可使用。此等之除蟲菊酯系殺蟲成分雖可單獨或作為二種以上之混合物使用，但較佳為包含美特寧。於此，所謂具有常溫揮散性，係意指在30℃之蒸氣壓為2×10-4 ～1×10-2 mmHg。美特寧、丙氟菊酯及拜富靈藉由具有常溫揮散性，由於經過長時間於持續性滅蚊線香之燃燒後，亦殘存在空氣中，故可長時間持續殺蟲效果。又，美特寧、丙氟菊酯及拜富靈藉由於揮散後一部分附著在壁面等，並藉由接觸具有停止在壁面等之習性的蚊類，可發揮持續的殺蟲效果。尚，在本說明書，殺蟲效果除了致死或擊倒害蟲的效果，成為亦包含害蟲不會靠近之害蟲忌避效果。As the insecticidal ingredient, the pyrethrin-based insecticidal ingredients with normal temperature volatility, methelthrin, profluthrin, or befulin are used. In the chemical structure of these pyrethroid insecticidal components, based on uneven carbon or double bonds, when there are optical isomers or geometric isomers, any isomer can be used . Although these pyrethrin-based insecticidal components can be used alone or as a mixture of two or more, they preferably contain methelthine. Here, the term "normal temperature volatility" means that the vapor pressure at 30°C is 2×10 -4 to 1×10 -2 mmHg. Metherine, Profluthrin and Bioflumide have a normal temperature volatility, and they remain in the air after being burned by a continuous mosquito-killing incense stick for a long time, so they can sustain a long-term insecticidal effect. In addition, Metenine, Profluthrin, and Byfulin will partially adhere to the wall surface after volatilization, and by contacting mosquitoes that have the habit of stopping on the wall surface, they can exert a continuous insecticidal effect. In addition, in this specification, the insecticidal effect not only kills or knocks down the pests, but also includes the pest repellent effect that the pests do not approach.
殺蟲成分的含量相對於持續性滅蚊線香全體的重量，較佳為0.1～5重量%，更佳為0.2～3重量%。殺蟲成分的含量未滿0.1重量%時，有得不到充分之殺蟲效果的可能性。殺蟲成分的含量超過5重量%時，由於殺蟲成分並非有助於直接燃燒的成分，故有發生持續性滅蚊線香熄滅的可能性。The content of the insecticidal component is preferably 0.1 to 5% by weight, and more preferably 0.2 to 3% by weight relative to the weight of the entire continuous mosquito-killing coil. When the content of the insecticidal ingredient is less than 0.1% by weight, there is a possibility that a sufficient insecticidal effect may not be obtained. When the content of the insecticidal ingredient exceeds 5% by weight, since the insecticidal ingredient is not an ingredient that contributes to direct combustion, there is a possibility that the mosquito-killing incense will be continuously extinguished.
作為碳化物基材，係使用碘吸附能為200mg/g以下之碳化物基材。作為碳化物基材，具體而言，可列舉木炭、竹炭、植物質之活性炭、椰子殼炭及咖啡粕炭等之源自植物的碳化物基材、以及碳黑、石墨、乙炔黑、煤炭質之活性炭及石油質的活性炭等之源自非植物質的碳化物基材，尤其是以源自植物質的碳化物基材較佳。針對細節雖在後述之實施例進行說明，但於持續性滅蚊線香摻合碘吸附能為200mg/g以下之碳化物基材時，可一邊防止因碳化物基材的碘吸附能導致之殺蟲成分的過剩分解，一邊可有效果的減低或緩和起因於持續性滅蚊線香的燃燒時之煙霧等之臭味或刺激。碳化物基材之碘吸附能超過200mg/g時，有殺蟲成分過剩分解，得不到充分的殺蟲效果之虞。又，於本發明之持續性滅蚊線香，亦可將碘吸附能不同之複數種類的碳化物基材以碘吸附能成為200mg/g以下的方式進行混合來使用。尚，碘吸附能係依據JIS K 1474所規定之活性炭試驗方法測定。As the carbide substrate, a carbide substrate with an iodine adsorption capacity of 200 mg/g or less is used. As the carbide substrate, specifically, carbon black, graphite, acetylene black, and coal-based carbide substrates such as charcoal, bamboo charcoal, plant-based activated carbon, coconut shell charcoal and coffee meal charcoal, etc. can be cited. Activated carbon and petroleum-based activated carbon are non-plant-derived carbide substrates, especially plant-derived carbide substrates. Although the details are described in the following examples, when the continuous mosquito-killing incense is blended with a carbide substrate with an iodine adsorption capacity of 200 mg/g or less, it can prevent the killing caused by the iodine adsorption energy of the carbide substrate. Excessive decomposition of insect components can effectively reduce or alleviate the odor or irritation caused by the smoke when the continuous mosquito coil is burned. When the iodine adsorption capacity of the carbide substrate exceeds 200 mg/g, the insecticidal components may decompose in excess, and a sufficient insecticidal effect may not be obtained. In addition, in the continuous mosquito-killing coil of the present invention, a plurality of types of carbide substrates with different iodine adsorption abilities can also be mixed and used so that the iodine adsorption energy becomes 200 mg/g or less. Still, the iodine adsorption energy is measured in accordance with the activated carbon test method specified in JIS K 1474.
碳化物基材的含量，較佳為相對於持續性滅蚊線香全體的重量，為20～80重量%。碳化物基材的含量未滿20重量%時，有無法充分緩和起因於燃燒時之煙霧等之臭味或刺激之虞。碳化物基材的含量超過80重量%時，有無法確保持續性滅蚊線香之成型性或強度之虞。The content of the carbide substrate is preferably 20 to 80% by weight with respect to the weight of the entire continuous mosquito coil. When the content of the carbide base material is less than 20% by weight, there is a possibility that the odor or irritation caused by smoke during combustion cannot be sufficiently alleviated. When the content of the carbide base material exceeds 80% by weight, the moldability or strength of the continuous mosquito-killing coil may not be ensured.
助燃劑係為了安定燃燒持續性滅蚊線香而摻合。增量劑係為了提高持續性滅蚊線香之成形性而摻合。黏結劑係結合原料作為凝固之黏接劑進行摻合。助燃劑、增量劑及黏結劑成為持續性滅蚊線香的基材者。例示合適之助燃劑時，可列舉木粉、除蟲菊萃取粕粉、柑橘類表皮粉、茶粉末、椰子殼粉末等。此等之助燃劑可單獨或作為二種以上之混合物使用。例示合適之增量劑時，可列舉矽藻土、滑石、黏土、高嶺土等。此等之增量劑可單獨或作為二種以上之混合物使用。例示合適之黏結劑時，可列舉磨碎麵粉、澱粉(α澱粉、木薯粉等)、甲基纖維素、羧基甲基纖維素(CMC)等。此等之黏結劑可單獨或作為二種以上之混合物使用。碳化物基材、助燃劑、增量劑及黏結劑為持續性滅蚊線香之基材，基材的含量，較佳為相對於持續性滅蚊線香全體的重量，為90重量%以上。Combustion aid is blended for stable burning and continuous mosquito-killing incense.

於本發明之持續性滅蚊線香，作為其他成分，亦可含有防黴劑、防腐劑、安定劑、效力增強劑、除臭劑等。例示防黴劑或防腐劑時，可列舉去氫乙酸鹽、山梨酸鹽、p-羥基苯甲酸鹽等。例示安定劑時，可列舉2,6-二-第三丁基-4-甲基酚(BHT)、2,2’-亞甲基雙(4-甲基-6-第三丁基酚)、2,2’-亞甲基雙(4-乙基-6-第三丁基酚)、4,4’-亞丁基雙(3-甲基-6-第三丁基酚)、4,4’-硫代雙(3-甲基-6-第三丁基酚)、2-第三丁基-6-(3-第三丁基-2-羥基-5-甲基苄基)-4-甲基苯基丙烯酸酯、2,4-二-第三丁基苯基3,5-二-第三丁基-4-羥基苯甲酸鹽等。藉由添加這般的安定劑，不僅在保存時之殺蟲成分的隨著時間的穩定性，亦可顯著增強煙燻時之穩定性，進而亦有助於揮散後之有效成分的效力持續性的提昇。作為安定劑的添加量，較佳為相對於殺蟲成分，摻合0.01～0.5倍量。例示效力增強劑時，可列舉胡椒基丁醚(piperonyl butoxide)、N-(2-乙基己基)-雙環[2,2,1]庚-5-烯-2,3-二羧基醯亞胺等。又，於持續性滅蚊線香，亦可含有孔雀綠(malachite green)、食品添加物(食用藍色1號、食用黃色4號、食用紅色106號等)等之著色劑。The continuous mosquito-killing incense of the present invention may also contain anti-mold agents, preservatives, stabilizers, potency enhancers, deodorants, etc., as other ingredients. When an antifungal agent or an antiseptic agent is exemplified, dehydroacetate, sorbate, p-hydroxybenzoate, and the like can be mentioned. Examples of stabilizers include 2,6-di-tert-butyl-4-methylphenol (BHT) and 2,2'-methylenebis(4-methyl-6-tert-butylphenol) , 2,2'-methylene bis (4-ethyl-6-tertiary butyl phenol), 4,4'-butylene bis (3-methyl-6-tertiary butyl phenol), 4, 4'-thiobis(3-methyl-6-tert-butylphenol), 2-tert-butyl-6-(3-tert-butyl-2-hydroxy-5-methylbenzyl)- 4-methylphenyl acrylate, 2,4-di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate, etc. By adding such a stabilizer, not only the stability of the insecticidal ingredients over time during storage, but also the stability during smoking can be significantly enhanced, which in turn contributes to the persistence of the effectiveness of the active ingredients after volatilization. The promotion. The amount of the stabilizer added is preferably 0.01 to 0.5 times the amount of the insecticidal component. When exemplifying potency enhancers, piperonyl butoxide, N-(2-ethylhexyl)-bicyclo[2,2,1]hept-5-ene-2,3-dicarboxyimide can be cited Wait. In addition, the continuous mosquito-killing incense may contain coloring agents such as malachite green, food additives (food blue No. 1, food yellow No. 4, food red No. 106, etc.).
〔燃燒時間〕 以往之滅蚊線香雖藉由燃燒中之煙燻揮散殺蟲成分，來防除蚊子等，但於就寢時等之使用，亦有避免煙霧產生的情況。本發明之持續性滅蚊線香由於即使燃燒後經過長時間，殺蟲成分亦殘存於空氣中，可持續殺蟲效果，故藉由將燃燒時間設定在適當的範圍，可提高可用性。本發明之持續性滅蚊線香從著火至燃盡為止的燃燒時間較佳為30分鐘以內。藉由將燃燒時間設定在30分鐘以內，於就寢中經過長時間，雖可防除蚊類，但在就寢前或剛就寢後之短時間當中，完成持續性滅蚊線香之燃燒，可不必擔心煙霧等安心就寢。尚，持續性滅蚊線香之燃燒後，殺蟲效果的持續時間(可防除蚊類的時間)較佳為8小時以上，更佳為10小時以上，最佳為12小時以上。藉由將燃燒後之殺蟲效果的持續時間設定在8小時以上，例如於夜間使用時，人類於一整夜不會被蚊類咬，可舒服地睡覺。又，若將每個燃燒時間設定在30分鐘以內，燃燒後之殺蟲效果的持續時間設定在8小時，由於人們要入睡時，持續性滅蚊線香的火消滅，故不必擔心火災，即使夜間亦可安心地使用。如此，本發明之持續性滅蚊線香雖燃燒時間為短時間，但由於經過長時間依然持續殺蟲效果，故適合於屋內之使用，尤其是適合在密閉性高之空間的使用。惟，本發明之持續性滅蚊線香當然亦可於屋外使用。〔Burning time〕 In the past, the mosquito-killing incense used smoke from burning to evaporate insecticidal ingredients to prevent mosquitoes, but it was used at bedtime to avoid smoke generation. The continuous mosquito-killing incense stick of the present invention remains in the air even after a long period of time after burning, so that the insecticidal effect can be sustained. Therefore, by setting the burning time in an appropriate range, the usability can be improved. The burning time of the continuous mosquito-killing incense of the present invention from ignition to exhaustion is preferably within 30 minutes. By setting the burning time within 30 minutes, after a long time during bedtime, although it can prevent mosquitoes, it can complete the continuous burning of the mosquito-killing incense before or just after bedtime, so there is no need to worry about smoke. Wait for peace of mind to go to bed. Furthermore, after the burning of the continuous mosquito-killing incense stick, the duration of the insecticidal effect (the time during which mosquitoes can be prevented) is preferably at least 8 hours, more preferably at least 10 hours, and most preferably at least 12 hours. By setting the duration of the burning insecticidal effect to more than 8 hours, for example, when used at night, humans will not be bitten by mosquitoes throughout the night and can sleep comfortably. In addition, if each burning time is set within 30 minutes, the duration of the insecticidal effect after burning is set at 8 hours. Since people are going to sleep, the fire of the mosquito-killing incense will be extinguished continuously, so there is no need to worry about fires, even at night It can also be used safely. In this way, although the burning time of the continuous mosquito-killing incense of the present invention is short, it has a continuous insecticidal effect after a long time, so it is suitable for indoor use, especially suitable for use in highly confined spaces. However, the continuous mosquito-killing incense of the present invention can of course also be used outdoors.
〔殺蟲成分每一單位時間之揮散量〕 本發明之持續性滅蚊線香藉由將在燃燒時之殺蟲成分每一單位時間之揮散量設定在適當的範圍，即使為短時間的燃燒，亦可將充分量之殺蟲成分揮散在空氣中。於此，持續性滅蚊線香為完全燃燒時之殺蟲成分的揮散量，係藉由於連結在裝有二氧化矽凝膠之玻璃管的排氣鐘當中，使持續性滅蚊線香完全燃燒，並藉由將排氣鐘內之空氣以泵吸引，困住藉由燃燒揮散之殺蟲成分，並將困住之殺蟲成分以氣體層析分析來算出。將如此所算出之殺蟲成分的揮散量除以燃燒時間之每一單位時間的揮散量，較佳為0.05～15mg/分鐘，更佳為0.1～10mg/分鐘。若殺蟲成分每一單位時間之揮散量為上述的範圍，即使30分鐘以下之短時間的燃燒，亦可將適當量之殺蟲成分揮散在空氣中。又，若殺蟲成分每一單位時間之揮散量為上述的範圍，即使碳化物基材之碘吸附能為200mg/g以下，亦可減低起因於燃燒時之煙霧等之臭味或刺激。殺蟲成分每一單位時間之揮散量未滿0.05mg/分鐘時，於30分鐘以下之短時間的燃燒，有無法將充分量之殺蟲成分揮散在空氣中，無法持續殺蟲效果之虞。殺蟲成分每一單位時間之揮散量超過15mg/分鐘時，有無法充分緩和起因於燃燒時之煙霧等之煙霧的臭味或刺激之虞。進而，由於殺蟲成分並非有助於直接燃燒之成分，故有發生持續性滅蚊線香的熄滅的可能性。〔Volatilization amount of insecticidal ingredients per unit time〕 The continuous mosquito-killing incense coil of the present invention, by setting the volatilization amount of the insecticidal component per unit time during combustion in an appropriate range, even if it is burned for a short time, a sufficient amount of the insecticidal component can be dispersed in the air. middle. Here, the continuous mosquito-killing incense is the volatilization amount of the insecticidal components when it is completely burned. The continuous mosquito-killing incense is completely burned by connecting to the exhaust clock of the glass tube filled with silica gel. And by sucking the air in the exhaust bell with a pump, trapping the insecticidal components volatilized by combustion, and calculating the trapped insecticidal components by gas chromatography. Dividing the volatilization amount of the insecticidal component calculated in this way by the volatilization amount per unit time of the burning time is preferably 0.05-15 mg/min, more preferably 0.1-10 mg/min. If the volatilization amount of the insecticidal ingredient per unit time is in the above range, even if it is burned for a short time of less than 30 minutes, the appropriate amount of the insecticidal ingredient can be dispersed in the air. Moreover, if the volatile amount of the insecticidal ingredient per unit time is within the above range, even if the iodine adsorption energy of the carbide substrate is 200 mg/g or less, the odor or irritation caused by smoke during combustion can be reduced. When the volatilization amount of the insecticidal ingredient per unit time is less than 0.05mg/min, burning in a short time of less than 30 minutes may not be able to evaporate the insecticidal ingredient in the air in sufficient amount, and the insecticidal effect may not be sustained. When the volatile amount of the insecticidal ingredient per unit time exceeds 15 mg/min, it may not be able to sufficiently alleviate the smell or irritation of the smoke caused by the smoke during combustion. Furthermore, since the insecticidal component is not a component that contributes to direct combustion, there is a possibility of continuous extinction of the mosquito-killing coil.
〔殺蟲成分維持率〕 在本發明之持續性滅蚊線香，將殺蟲成分的摻合量定為CI (mg)，將完全燃燒時之殺蟲成分的揮散量定為V(mg)時，殺蟲成分的揮散量V與殺蟲成分的摻合量CI 的比率即殺蟲成分維持率，較佳為滿足以下之式(1)。 殺蟲成分維持率=(V/CI )×100≧40 ･･･(1) 藉由滿足式(1)的條件，由於在持續性滅蚊線香的保存中及燃燒中過剩分解殺蟲成分，故可一邊抑制製造時之殺蟲成分的摻合量，一邊於燃燒時將充分量之殺蟲成分揮散在空氣中。殺蟲成分維持率未滿40%時，有於持續性滅蚊線香之製造時，必要之殺蟲成分的摻合量增大，變成經濟上不利之虞。又，由於殺蟲成分並非有助於直接燃燒之成分，故藉由增加殺蟲成分的摻合量，有發生持續性滅蚊線香的熄滅的可能性。[Insecticidal ingredient maintenance rate] In the continuous mosquito-killing incense of the present invention, the blending amount of the insecticidal ingredient is defined as C I (mg), and the amount of the insecticidal ingredient volatile when completely burned is defined as V (mg) At this time, the ratio of the volatilization amount V of the insecticidal ingredient to the blending amount C I of the insecticidal ingredient, that is, the insecticidal ingredient maintenance rate, preferably satisfies the following formula (1). Insecticidal component maintenance rate=(V/C I )×100≧40 ･･･(1) By satisfying the condition of formula (1), the insecticidal component is excessively decomposed during the preservation and burning of the continuous mosquito-killing incense Therefore, while suppressing the blending amount of insecticidal ingredients during manufacture, sufficient amount of insecticidal ingredients can be volatilized in the air during combustion. When the insecticidal ingredient retention rate is less than 40%, the necessary amount of the insecticidal ingredient will increase during the manufacture of the continuous mosquito-killing incense, which may become economically disadvantageous. In addition, since the insecticidal component is not a component that contributes to direct combustion, by increasing the blending amount of the insecticidal component, there is a possibility of continuous extinguishment of the mosquito-killing incense.
〔殺蟲成分/吸附能比〕 在滅蚊線香，將殺蟲成分的摻合量定為CI (mg)，將碳化物基材的摻合量定為CB (g)，將碳化物基材之碘吸附能定為A(mg/g)時，碳化物基材的摻合量CB 與碳化物基材之碘吸附能A的乘積，表示持續性滅蚊線香全體之碘吸附性的總量。於此，相對於碳化物基材的摻合量CB 與碳化物基材之碘吸附能A的乘積之殺蟲成分的摻合量CI 的比率即殺蟲成分/吸附能比，對殺蟲成分的揮散量帶來影響。在本發明之持續性滅蚊線香，殺蟲成分/吸附能比較佳為滿足以下之式(2)。 殺蟲成分/吸附能比=CI /(CB ×A)≧3×10-2 ･･･(2) 藉由滿足式(2)，相對於製造時之殺蟲成分的摻合量，於持續性滅蚊線香的保存中及燃燒中，藉由碳化物基材之碘吸附能分解之殺蟲成分的比例成為非常小者。因此，於持續性滅蚊線香的保存中及燃燒中，即使分解一部分之殺蟲成分，亦可於燃燒後，揮散可長時間持續殺蟲效果之適當量的殺蟲成分。殺蟲成分/吸附能比未滿3×10-2 時，相對於製造時之殺蟲成分的摻合量，於持續性滅蚊線香之保存中及燃燒中，藉由碳化物基材之碘吸附能分解之殺蟲成分的比例增大，有於燃燒時揮散的殺蟲成分不足之虞。[Insecticidal ingredient/adsorption energy ratio] In the mosquito-killing coil, the blending amount of the insecticidal ingredient is set as C I (mg), and the blending amount of the carbide base material is set as C B (g), and the carbide When the iodine adsorption energy of the base material is set as A (mg/g), the product of the blending amount of the carbide base material C B and the iodine adsorption energy A of the carbide base material represents the iodine adsorption capacity of the entire continuous mosquito-killing coil The total amount. Here, the ratio of the blending amount C I of the pesticidal component to the product of the blending amount C B of the carbide substrate and the product of the iodine adsorption energy A of the carbide substrate is the pesticidal component/adsorption energy ratio. The volatilization amount of insect components has an impact. In the continuous mosquito-killing incense of the present invention, the insecticidal component/adsorption energy ratio is preferably to satisfy the following formula (2). Insecticidal component/adsorption energy ratio=C I /(C B ×A)≧3×10 -2 ･･･(2) By satisfying formula (2), relative to the blending amount of the insecticidal component at the time of manufacture, During the preservation and burning of the continuous mosquito-killing coil, the proportion of insecticidal components that can be decomposed by the iodine adsorption of the carbide substrate becomes very small. Therefore, during the preservation and burning of the continuous mosquito-killing incense, even if a part of the insecticidal components are decomposed, after the combustion, an appropriate amount of the insecticidal components that can sustain the insecticidal effect for a long time can be volatilized. When the ratio of insecticidal ingredient/adsorption energy is less than 3×10 -2 , relative to the blending amount of the insecticidal ingredient at the time of manufacture, the iodine of the carbide substrate is used during the preservation and burning of the continuous mosquito-killing coil. The proportion of the insecticidal components that can be absorbed and decomposed increases, and there is a risk that the insecticidal components that volatilize during combustion are insufficient.
〔防除對象害蟲〕 本發明之持續性滅蚊線香作為防除對象之害蟲雖並未特別限定，但例如可列舉尖音家蚊、三斑家蚊、熱帶家蚊、地下家蚊等之家蚊類、埃及斑蚊、白線斑蚊等之伊蚊類、搖蚊類、家蠅類、白斑蛾蚋類、蚤蠅類、蜂類、虻類、蚋類、蠓類、衣蛾類等之飛翔害蟲、以及德國姬蠊、美洲家蠊、黑褐家蠊等之蜚蠊類、蟎類、蟻類、溫帶臭蟲、囓蟲、食骸蟲、玉米象等之爬行害蟲，此等之害蟲當中，尤其是特對於家蚊類、伊蚊類，有效性高。 [實施例]〔Pest control target〕 Although the pests to be controlled by the continuous mosquito-killing incense of the present invention are not particularly limited, examples include house mosquitoes such as acupuncture mosquitoes, three-spot house mosquitoes, tropical house mosquitoes, underground house mosquitoes, aegypti mosquitoes, etc. Flying pests such as Aedes, chironomids, house flies, gnats, fleas, bees, fly, gnats, midges, cloth moths, etc., and German cockroaches Cockroaches, mites, ants, temperate bed bugs, rodents, skeletal insects, corn weevil and other crawling pests such as the American cockroach, the black brown cockroach, etc. Among these pests, especially the house mosquito Class, Aedes class, high effectiveness. [Example]
〔實施例1〕 混合作為碳化物基材之碘吸附能為25mg/g之木炭粉A(50重量份)、作為殺蟲成分之美特寧(1.5重量份)、作為香料成分之包含佳樂麝香及麝香酮等的混合香料(0.8重量份)、作為助燃劑･增量劑之植物性粉末即除蟲菊萃取粕粉(17重量份)、木粉(10.7重量份)及矽藻土(3重量份)、以及作為黏結劑之α澱粉(14重量份)，及羧基甲基纖維素(CMC)(3重量份)，對此添加水(90重量份)並充分捏合。將捏合物放在擠出機成型成棒狀，然後，乾燥至使水分含量成為7～10重量%左右為止，以製作實施例1之持續性滅蚊線香。實施例1之持續性滅蚊線香係殺蟲成分/吸附能比為1.2，且滿足前述之式(2)的條件者。[Example 1] Mixed with charcoal powder A (50 parts by weight) with an iodine adsorption capacity of 25 mg/g as a carbide substrate, Metanin (1.5 parts by weight) as an insecticidal ingredient, and a fragrance ingredient containing Gallo Musk and Muscone, etc. Blended spices (0.8 parts by weight), plant powders used as combustion aids and extenders, namely pyrethrum extract meal powder (17 parts by weight), wood flour (10.7 parts by weight) and diatomaceous earth (3 parts by weight), and As a binder, α starch (14 parts by weight) and carboxymethyl cellulose (CMC) (3 parts by weight) are added with water (90 parts by weight) and fully kneaded. The kneaded product was placed in an extruder and formed into a rod shape, and then dried until the moisture content became about 7-10% by weight to produce the continuous mosquito-killing incense of Example 1. The insecticidal component/adsorption energy ratio of the continuous mosquito-killing incense of Example 1 is 1.2 and meets the conditions of the aforementioned formula (2).
將實施例1之持續性滅蚊線香於10塌塌米的房間(面積16.7m2 、高度2.5m、容積41.7m3 )使用時，雖約23分鐘已燃盡，但燃燒後經過12小時，蚊類等之各種害蟲並未靠近。由此可知，認為實施例1之持續性滅蚊線香的燃燒後，經過12小時，於室內亦充分殘存殺蟲成分。又，實施例1之持續性滅蚊線香係燃燒中所產生之煙霧量少，不會感到刺激臭，並產生淡淡花香的氣味。此氣味會帶來放鬆感，且適合於寢室之使用。When the continuous mosquito-killing incense of Example 1 was used in a room of 10 tatami meters (area 16.7m 2 , height 2.5m, volume 41.7m 3 ), although it burned out in about 23 minutes, 12 hours passed after burning. Various pests such as mosquitoes are not close. From this, it can be seen that after 12 hours after the burning of the continuous mosquito-killing incense of Example 1, the insecticidal components remained sufficiently in the room. In addition, the continuous mosquito-killing incense system of Example 1 generates a small amount of smoke during combustion, does not feel irritating odor, and produces a light floral odor. This smell will bring a sense of relaxation and is suitable for bedroom use.
〔實施例2～12〕 使用作為碳化物基材之碘吸附能為25mg/g之木炭粉A，及碘吸附能為838mg/g之木炭粉B，在表1所示之摻合，依照實施例1，製作具有本發明之特徵構成的持續性滅蚊線香(實施例2～12)。實施例2～12之持續性滅蚊線香係殺蟲成分/吸附能比為3.1×10-2 ～2.2，皆為滿足前述之式(2)的條件者。[Examples 2-12] Charcoal powder A with an iodine adsorption energy of 25 mg/g and charcoal powder B with an iodine adsorption energy of 838 mg/g were used as carbide substrates. The blending shown in Table 1 is based on the implementation Example 1: Making a continuous mosquito-killing incense with the characteristic structure of the present invention (Examples 2-12). The insecticidal component/adsorption energy ratio of the continuous mosquito-killing incense in Examples 2-12 is 3.1×10 -2 ～2.2, all satisfying the conditions of the aforementioned formula (2).
〔比較例1～3〕 使用作為碳化物基材之碘吸附能為25mg/g之木炭粉A，及/或碘吸附能為838mg/g之木炭粉B，在表2所示之摻合，依照實施例1，製作不具有本發明之特徵構成的持續性滅蚊線香(比較例1～3)。比較例1～3之持續性滅蚊線香相較本發明之規定，碳化物基材之碘吸附能為更大之例，對於殺蟲成分/吸附能比，為7.2×10-3 ～2.2×10-2 ，為皆未滿足前述之式(2)的條件者。[Comparative Examples 1 to 3] Use charcoal powder A with an iodine adsorption energy of 25 mg/g as a carbide substrate, and/or charcoal powder B with an iodine adsorption energy of 838 mg/g, blend as shown in Table 2, According to Example 1, a continuous mosquito-killing incense which does not have the characteristic structure of the present invention (Comparative Examples 1 to 3) was produced. Compared with the provisions of the present invention, the continuous mosquito-killing incense of Comparative Examples 1 to 3 has a higher iodine adsorption energy of the carbide substrate, and the ratio of insecticidal components/adsorption energy is 7.2×10 -3 ～2.2× 10 -2 , which means that none of the conditions of the aforementioned formula (2) are met.
〔參考例〕 未使用具有碘吸附能之碳化物基材，在表2所示之摻合，依照實施例1，製作持續性滅蚊線香(參考例)。[Reference example] Without using a carbide substrate with iodine adsorption ability, the blending shown in Table 2 was followed in accordance with Example 1 to produce a continuous mosquito-killing incense (reference example).
使用實施例1～12、比較例1～3及參考例的持續性滅蚊線香，進行下述(1)～(4)所示之各試驗。Using the continuous mosquito-killing coils of Examples 1 to 12, Comparative Examples 1 to 3, and Reference Example, each test shown in the following (1) to (4) was performed.
(1)隨時間的穩定性 將於50℃保存1個月後之持續性滅蚊線香所包含之殺蟲成分藉由氣體層析進行分析，保存1個月後之殺蟲成分的含量、與製造時之殺蟲成分的摻合量，算出殺蟲成分的回收率。依照下述之基準，判定隨時間的穩定性。 A：殺蟲成分之回收率95%以上 B：殺蟲成分之回收率90%以上、且未滿95% C：殺蟲成分之回收率未滿90%(1) Stability over time The insecticidal components contained in the continuous mosquito-killing coils stored at 50°C for 1 month are analyzed by gas chromatography. The content of the insecticidal ingredients after storage for 1 month is mixed with the insecticidal ingredients at the time of manufacture. Calculate the recovery rate of the insecticidal ingredients. Determine the stability over time according to the following criteria. A: The recovery rate of insecticidal ingredients is more than 95% B: The recovery rate of insecticidal ingredients is more than 90% and less than 95% C: The recovery rate of insecticidal ingredients is less than 90%
(2)殺蟲成分維持率 係藉由於連結在裝有二氧化矽凝膠之玻璃管的排氣鐘當中，使持續性滅蚊線香完全燃燒，並藉由將排氣鐘內之空氣以泵吸引，困住藉由燃燒揮散之殺蟲成分，並將困住之殺蟲成分以氣體層析分析，來算出持續性滅蚊線香完全燃燒時之殺蟲成分的揮散量。而且從算出之揮散量與製造時之殺蟲成分的摻合量，根據上述之式(1)算出殺蟲成分維持率。(2) Maintenance rate of insecticidal ingredients The continuous mosquito-killing incense is completely burned by connecting it to the exhaust clock of the glass tube equipped with silica gel, and the air in the exhaust clock is sucked by the pump, trapped by burning and evaporating The insecticidal components of the trapped insecticidal components are analyzed by gas chromatography to calculate the volatile amount of the insecticidal components when the continuous mosquito-killing incense is completely burned. Furthermore, from the calculated amount of volatile and the blending amount of the insecticidal ingredient at the time of manufacture, the insecticidal ingredient retention rate is calculated according to the above formula (1).
(3)嗜好性 於直徑20cm、高度40cm之玻璃圓筒內，使持續性滅蚊線香燃燒，10人之測試人員針對刺激緩和性及氣味的嗜好性，將最高點作為10、最低點作為1來評價。作為藉由官能試驗之嗜好性的試驗結果，算出藉由10人之測試人員的評點之平均值。(3) Hobbies In a glass cylinder with a diameter of 20cm and a height of 40cm, the continuous mosquito-killing incense was burned. A 10-person tester rated the highest point as 10 and the lowest point as 1 for irritation mitigation and odor preference. As the test result of the preference by the sensory test, the average value of the evaluation by 10 testers was calculated.
(4)實地殺蟲效力試驗 於關閉之25m3 房間的中央，燃燒持續性滅蚊線香。自燃燒8小時後，放入尖音家蚊雌成蟲50隻曝露2小時後，並回收全部之供試蚊。其間，伴隨時間經過，計數落下仰轉之尖音家蚊雌成蟲，將落下仰轉25隻尖音家蚊雌成蟲的時間點定為KT50 值(小數點以下四捨五入)。(4) The field insecticidal efficacy test was conducted in the center of a closed 25m 3 room, and the continuous mosquito-killing incense was burned. After 8 hours of self-burning, 50 female adults of Jianyin house mosquitoes were put in and exposed for 2 hours, and all the test mosquitoes were recovered. In the meantime, with the passage of time, count the falling and turning female adults of Acanthus mosquitoes, and determine the time point when 25 female adults of Acanthus mosquitoes fell and turning upside down as the KT 50 value (rounded up to the nearest decimal point).
含有美特寧、丙氟菊酯或拜富靈作為殺蟲成分，且含有碘吸附能為200mg/g以下之碳化物基材之實施例1～12之持續性滅蚊線香，確認隨時間的穩定性優異，何一者皆殺蟲成分維持率為40%以上，即使於30分鐘以內之短時間的燃燒，自燃燒12小時後之KT50 值成為30分鐘以下，持續性得到優異之殺蟲效果。認為實施例1～12之持續性滅蚊線香由於得到與未摻合具有碘吸附能之碳化物基材的參考例為相同程度以上之隨時間的穩定性，及自燃燒12小時後之殺蟲效果，故藉由抑制碳化物基材之碘吸附能為200mg/g以下，不會產生藉由碳化物基材之過剩殺蟲成分的分解。The continuous mosquito-killing incense of Examples 1 to 12 containing methelthrin, profluthrin or Bayefulin as insecticidal ingredients and a carbide substrate with an iodine adsorption capacity of 200 mg/g or less. Excellent stability, maintenance rate of insecticidal ingredients is more than 40% for any of them, even if it is burned for a short time within 30 minutes, the KT 50 value after 12 hours of burning becomes less than 30 minutes, and the sustainability is excellent. Effect. It is believed that the continuous mosquito-killing incense sticks of Examples 1-12 have the same degree of stability over time as the reference example that does not incorporate a carbide substrate with iodine adsorption capacity, and it kills insects after 12 hours of combustion. The effect is that by suppressing the iodine adsorption energy of the carbide base material to 200 mg/g or less, the decomposition of the excessive insecticidal components of the carbide base material will not occur.
又，參考例之持續性滅蚊線香，相對於擔心煙臭性或煙霧量的多量性，實施例1～12之持續性滅蚊線香係任何皆於燃燒後飄出嗜好性高之芳香，亦不會過度充滿煙霧，於刺激緩和性及氣味之嗜好性優異之實際使用，係容易使用者。由此可知，認為實施例1～12之持續性滅蚊線香即使碳化物基材之碘吸附能為200mg/g以下，亦充分得到減低起因於燃燒時之煙霧等之臭味或刺激的效果。In addition, the continuous mosquito-killing incense of the reference example, compared with the worry about the odor of smoke or the abundance of the amount of smoke, the continuous mosquito-killing incense of Examples 1-12 is any kind of fragrance that emits a high taste after burning. It will not be over-filled with smoke, and it is easy to use for practical use with excellent irritation mitigation and odor preference. From this, it can be seen that the continuous mosquito-killing coils of Examples 1 to 12 have a sufficient effect of reducing the odor or irritation caused by smoke during combustion even if the iodine adsorption energy of the carbide substrate is 200 mg/g or less.
尚，實施例1～12之持續性滅蚊線香當中，觀察到殺蟲成分每一單位時間之揮散量比較低者(實施例4～6,8)，有效力稍微降低的傾向。又，於每一單位時間的揮散量為10.2mg/分鐘超大之實施例3，有持續性滅蚊線香的燃燒無法持續到最後的情況。因此，殺蟲成分每一單位時間之揮散量較佳為0.05～15mg/分鐘，更佳為0.1～10mg/分鐘。Moreover, among the continuous mosquito-killing incense coils of Examples 1-12, it was observed that those with relatively low volatilization amount of insecticidal ingredients per unit time (Examples 4-6, 8) tended to slightly decrease their effective power. In addition, in Example 3 where the volatilization amount per unit time is 10.2 mg/min, which is extremely large, there is a situation where the continuous mosquito-killing incense cannot be burned to the end. Therefore, the volatile amount of the insecticidal ingredient per unit time is preferably 0.05-15 mg/min, more preferably 0.1-10 mg/min.
實施例9與實施例1比較時，雖殺蟲成分及碳化物基材的摻合量為同一，且僅香料成分的種類不同，但殺蟲成分維持率及自燃燒12小時後之KT50 值並無太大差異。實施例10與實施例1比較時，雖殺蟲成分及碳化物基材的摻合量為同一，且於未摻合香料成分的點不同，但殺蟲成分維持率及自燃燒12小時後之KT50 值並無太大差異。由此可知，認為香料成分的種類或摻合量，對藉由碳化物基材之碘吸附能之殺蟲成分的分解不會帶來重大的影響。When comparing Example 9 with Example 1, although the blending amount of the insecticidal component and the carbide base material are the same, and only the types of fragrance ingredients are different, the insecticidal component retention rate and the KT 50 value after 12 hours of combustion There is not much difference. When Example 10 is compared with Example 1, although the blending amount of the insecticidal component and the carbide substrate is the same, and they are different at the point where the fragrance component is not blended, the insecticidal component retention rate and the post-combustion rate after 12 hours are different. There is not much difference in the KT 50 value. It can be seen from this that it is believed that the type or blending amount of the fragrance component will not have a significant impact on the decomposition of the insecticidal component by the iodine adsorption energy of the carbide substrate.
對此，如比較例1～3般，作為殺蟲成分，雖含有美特寧，但含有碘吸附能超過200mg/g之碳化物基材時，殺蟲成分之隨時間的穩定性並不足夠，殺蟲成分維持率低於40%，自燃燒12小時後之KT50 值亦成為120分鐘以上，得不到充分之殺蟲效果。此被認為是因為藉由碳化物基材之碘吸附能超過200mg/g，產生藉由碳化物基材之過剩殺蟲成分的分解。又，於比較例1～3之持續性滅蚊線香，對於藉由香料成分之芳香性亦難以感受到，成為感覺到了香調變質的結果。 [產業上之可利用性]In this regard, as in Comparative Examples 1 to 3, although Methelin is contained as the insecticidal ingredient, the stability of the insecticidal ingredient over time is not sufficient when it contains a carbide substrate with an iodine adsorption capacity of more than 200 mg/g. , The insecticidal component maintenance rate is less than 40%, and the KT 50 value after burning for 12 hours has also become more than 120 minutes, and sufficient insecticidal effect cannot be obtained. This is believed to be because the iodine adsorption energy of the carbide substrate exceeds 200 mg/g, and the decomposition of the excess insecticidal components of the carbide substrate occurs. In addition, in the continuous mosquito-killing incense of Comparative Examples 1 to 3, it was difficult to perceive the aroma of the fragrance component, and it was a result of the deterioration of the scent.
