温度域である。The zeolite-activated carbon composite of the present invention having the above-mentioned antibacterial, antifungal, and COD lowering functions, and preferably additionally having moisture absorption and dew condensation prevention functions, is prepared as follows. Powdered or granular natural or synthetic zeolite that retains metal ions with bactericidal activity, or a mixture of this and zeolite that does not retain the above metal ions, and activated carbon (dry product treated as described above or heat activated) The heat-fusible fibers are preferably added in an amount of 3 to 67% based on the weight of the mixture (anhydrous basis) and mixed.

The above-mentioned fibers become softened or molten in the mixing step, and are in a desirable state where they are entangled with zeolite particles or activated carbon particles. Additionally, binders such as Niraporan N-1004 may be added to the above mixtures.
may be added in an amount of 4 to 35% and mixed in the above temperature range. The mixture obtained above is further pressure-molded in the above-mentioned temperature range, preferably at a temperature of 100'' to 270°C, to obtain the final zeolite-activated carbon composite of the present invention having antibacterial, antifungal, and COD lowering functions. The molding pressure in this case is preferably within the range of 2 to 250 KFJ/cut, although the required strength and appearance of the molded product vary depending on the density. The zeolite-activated carbon composite of the present invention may contain a small amount of non-flammable or flame-retardant lightweight material. In this case, the lightweight material used may include paper, pulp,
Wood flour and the like are difficult to use because they are flammable, so inorganic fillers and lightweight materials such as silica, alumina, perlite, rock wool, glass fiber, and carbon fiber are preferred for the present invention. In addition, pigments for coloring, fluorescent agents, chemical powders, metal powders, synthetic rubber to improve elasticity, and high water absorption resin powder or fibers to improve water absorption are further added as minor components. be able to.
