PROBLEM TO BE SOLVED: To develop a material allowing few transmission of fuel gas, satisfying emission regulations, and reducing production cost and to provide a plastic filler neck, which is formed by using the material, for an automobile. SOLUTION: The plastic filler neck for the automobile is manufactured by using a nanoclay/resin composite as a material. The nanoclay/resin composite is produced by dispersing organized clay, which is prepared by performing cation exchange between smectite-based clay swelled in water and an organic modifier, in a resin. In another embodiment, the material for the plastic filler neck is a nanoclay/resin composite produced by dispersing nanoclay, which is prepared by high-pressure spray drying slurry consisting of smectite-based clay and water, in a resin. Preferably, the smectite-based clay is one or more kinds of clay selected among montmorillonite, hectorite and bentonite. The resin is any one selected from a group comprising polyamide and polyolefin, desirably. COPYRIGHT: (C)2009,JPO&INPIT
