<p><P>PROBLEM TO BE SOLVED: To provide a solution to the problems in which a synthetic binder prepared by kneading an epoxy resin with a ceramic fiber tends to produce a fiber mass and liquid sagging, so that its handling is troublesome, and when this synthetic binder is mixed with aggregates to form a water and air permeable structure, the resin component flows downward during curing to allow the concentration of the resin to be higher in the lower part and lower in the upper part, resulting in reduction of surface strength and durability to prevent obtaining a desired product stably. <P>SOLUTION: The synthetic binder in which the epoxy resin is kneaded with the ceramic fiber material from which a shot part (a glass ball prepared at the tip of the fiber material) is removed can have high flowability, so that the fiber mass is not easily produced and the handling is easier when it is conveyed in a can. A method for producing the water and gas permeable structure having a large specific surface area comprises mixing inorganic aggregates to the synthetic binder, kneading them with a solvent and a curing agent, and then blowing hot air to cure them. <P>COPYRIGHT: (C)2003,JPO</p> |
