초록

휘발성 유기화합물을 제거하는 허니콤 흡착제의 제조 성분인 무기질 섬유에 흡착력이 뛰어난 제올라이트를 화학 결합시켰다. 무기질 섬유를 염산, 황산 또는 플루오르화 수소산 등으로 처리하여 표면의 불순물을 제거하여 제올라이트의 접합 능력을 향상시켰다. 무기질 섬유와 제올라이트의 표면에 매달은 클로로프로필, 아미노프로필 또는 에폭시기 등을 서로 반응시켜 두 물질을 화학 결합시켰으며, 연결 화합물로 고분자 폴리에틸렌이민을 사용하기도 하였다. 결합상태는 전자현미경으로 관찰하였고, BET 표면적 분석을 통하여 제올라이트 접합량을 유추하였다. 폴리에틸렌이민을 사용하면 제올라이트를 무기질 섬유에 많이 결합시킬 수 있었다.

Zeolites with excellent adsorption capacity of volatile organic compounds were attached onto inorganic fibers which were the raw materials of honeycomb-type adsorbers. The amounts of zeolite particles attached onto the fibers considerably increased by treating them with hydrochloric acid, sulfuric acid, or hydrofluoric acid. Various functional groups such as chloropropyl, aminopropyl and epoxy groups of silane compounds, and amine groups of polyethylenimine were employed as covalent linkage materials between the fibers and zeolite particles. The state of the fibers coated with zeolite particles was examined by scanning electron microscopy, and the amounts of zeolite particles bound to the fibers were estimated from their BET surface areas. The largest amount was obtained when polyethylenimine was employed as a linkage material. Polyethylenimine was the most effective for attaching zeolite particles onto the inorganic fibers among various linkers employed.
