LAMINATED SHEET MATERIAL WITH PHOTOCATALYTIC FUNCTION AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To reduce drop of a photocatalyst with excellent mechanical strength while maintaining high catalytic function by providing a reinforcing sheet for transmitting light, gas and liquid on one or both surfaces of a sheet having photocatalytic function. SOLUTION: A reinforcing sheet for transmitting light, gas and liquid is provided on one or both surfaces of a sheet having photocatalytic function. As the reinforcing sheet for transmitting the light, gas and liquid, woven fabric, knitted fabric, nonwoven fabric or net is used. As the sheet having the photocatalytic function, a sheet obtained by carrying semiconductor photocatalyst on a surface of in a sheet base material or composite sheet obtained by mixing semiconductor photocatalytic substance with other material and molding the mixture in a sheet-like material is used. As semiconductor photocatalytic powder, titanium oxide, strontium titanate, or zinc oxide is used. Its mean particle size is preferably 150μm or less.
