MOISTURE-CONDITIONING BUILDING MATERIAL AND ITS PRODUCTION PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a lightweight moisture-conditioning building material excellent in moisture absorption/desorption property, fireproofness, fire resistance, machinability, dimensional stability and property with respect to nailing.;SOLUTION: This moisture-conditioning building material of claim 1 consists of a moisture absorption/desorption material composition obtained by mixing different kinds of moisture absorption/desorption materials together, an inorganic material such as dihydrate gypsum, hydraulic material and perlite, and reinforcing fiber. This moisture-conditioning building material of claim 2 is the building material of claim 1, wherein the moisture absorption/ desorption material composition comprising different kinds of moisture absorption/desorption materials, consists essentially of diatomaceous earth. This moisture-conditioning building material of claim 3 is the building material of claim 1 or claim 2, wherein the content of the moisture absorption/desorption material composition consisting essentially of diatomaceous earth, in a raw material for the building material, which raw material consists of the above moisture absorption/desorption material composition, inorganic material and reinforcing fiber, is 2-90 wt.%. This production process of the claim 4 comprises preparing a mixed slurry by mixing the above raw material for the building material with water, subjecting the resulting mixed slurry to papermaking to form a sheet having a prescribed thickness, and thereafter drying the sheet.;COPYRIGHT: (C)2002,JPO
