PROBLEM TO BE SOLVED: To provide a termite pest control agent where natural colemanite ore and boric acid compound are strongly bounded, capable of holding termite preventive performance for long time without using an insecticidal component of an organic compound, and a termite prevention fabric basis by applying the termite pest control agent.SOLUTION: By forming a glassy by a boron compound only with a simple heating treatment of a natural colemanite ore and a boric acid compound, a state that the glassy is bound to the natural colemanite ore with graze is formed and it is used as a termite pest control agent at a state that natural colemanite ore and boric acid compound are stably bounded.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】 有機化合物の殺虫成分を全く使用せずに、防蟻性能を長く保持できる天然コレマナイト鉱物とホウ酸化合物とが強く結合したシロアリ防除剤、および同シロアリ防除剤を応用した防蟻布基礎を提供する。【解決手段】 天然のコレマナイト鉱物とホウ酸化合物とを簡単な加熱処理だけでホウ素化合物がガラス質を形成して、天然のコレマナイト鉱物に対して釉薬的に結合した状態を形成させて天然のコレマナイト鉱物とホウ酸化合物とが安定に結合した状態のシロアリ防除剤として利用すること。【選択図】 図1
