Moistureproof antifungal zeolite composition and its production

Abstract

Abstract PURPOSE:To obtain the titled composition with hygroscopicity inherent in zeolite suppressed, suitable as additives to polymeric materials, by coating a fluororesin on the surface of activated zeolite having antifungal metal. CONSTITUTION:Either natural or synthetic zeolite with a molar ratio: SiO2/Al2 O3>=1.5 (e.g., analycime, A-type zeolite) is immersed in an aqueous solution of antifungal metal (e.g., Ag, Cu, Zn) ion to perform ion exchange to prepare activated zeolite containing the antifungal metal. The resulting zeolite is impregnated at >=60 deg.C with either fluororesin coating agent or its solution followed by separation of the solid phase from the liquid phase, the resultant zeolite phase being heated to >=50 deg.C to expel the residual solvent, thus obtaining the objective composition.
