INTERIOR BUILDING MATERIAL, SCREEN, AND BLIND HAVING FUNCTIONAL MATERIAL LAYER FORMED OF BRYOZOA COMPOSITION

摘要

PROBLEM TO BE SOLVED: To solve the following problem: elimination of health hazards (a building syndrome, a sick-house syndrome, etc.) caused by an indoor environment is very difficult by artificial ventilation or a mechanical ventilating means.;SOLUTION: There is disclosed an interior building material 11 which consists of a core 12 and a functional material layer 13 arranged at least on one surface of the core. The functional material layer contains therein Bryozoa (Bryozoa fossil) of 25 to 80 mass%, zeolite of 50 mass% or less, cement of 20 mass % or less, calcium hydroxide of 10 mass% or less, and fibrous material of 2 mass % or less. There are also disclosed a screen and a blind. By virtue of the functional material layer, noxious material such as formaldehyde, acetoaldehyde, etc., is eliminated. Further the functional material layer exerts a humidity conditioning function.;COPYRIGHT: (C)2005,JPO&NCIPI
