PROBLEM TO BE SOLVED: To provide a heat shielding insect proof mesh sheet for improving human living environment in summer time by especially preventing flying insect pests such as mosquito and moth from coming flying and reducing an increase of temperature about 1 to 3°C by shielding effect, and maintaining pest control effects for a long time by preventing volatile loss of an insecticide component by heat shielding effects.SOLUTION: A flexible mesh sheet constituted by coarse fabric as a base fabric and a heat shielding resin layer which coats the whole coarse fabric, and having a plurality of cavity part is controlled to have an area per a cavity part of 0.25 mm2 to 10 mm2, contain 0.3 to 10 mass% of a pyrethroid compound inclusion complex in the heat shielding resin layer, make the pyrethroid compound inclusion complex carried in a compound for packaging and be controlled released with time.COPYRIGHT: (C)2015,JPO&INPIT【課題】特に蚊や蛾などの飛翔性害虫の飛来を抑止し、しかも遮熱効果により温度の上昇を1~3℃程度下げることで夏季の人居環境を改善する遮熱防虫メッシュシートで、遮熱効果により防虫剤成分の揮発ロスを抑止することで防虫効果が長期間持続するメッシュシートの提供。【解決手段】粗目織物を基布として、粗目織物全面を被覆する遮熱性樹脂層とで構成された、多数の空隙部を有する可撓性メッシュシートにおいて、空隙部1個あたりの面積0.25mm2~10mm2を有し、遮熱性樹脂層にピレスロイド系化合物包接体を0.3~10質量%含み、ピレスロイド系化合物を包接用化合物内部に担持させ、かつ経時的に徐放されるようコントロールする。【選択図】図1
