50 μm (average particle size: 35 μm)] and further mixed well to prepare a particle suspension. This particle suspension was applied and impregnated on a glass nonwoven fabric having a thickness of 0.3 mm (40 g / m ² ) by a dip dipping method, and then heated and dried at 175 ° C. to obtain a sheet. The specific surface area of the sheet material was about 33 m ² / g, and the porosity was about 91%.

The sheet-like deodorizing material thus obtained is used for the purpose of preventing a small amount of particles such as metal and / or metal oxide particles and adsorbent particles from falling off, or for enhancing decorativeness. It is preferable to attach a fine surface protective material to the both surfaces such that particles such as adsorbent particles do not pass through. Examples of the material of the surface protective material include woven fabric, nonwoven fabric, and paper having air permeability. Woven fabrics include natural or synthetic fibers such as cotton and polyester; paper includes pulp paper, synthetic paper, filter paper, etc. There is. It is only necessary to select from these.

The bonding of the air-permeable surface protective material can be carried out by laminating the surface protective material on both sides of the sheet-like deodorizing material, and applying heat and pressure. At this time, the heating or pressurizing conditions vary depending on the thermoplastic resin used for the production of the sheet-like deodorizing material.
