METHOD FOR PRODUCING INORGANIC SHEET

摘要

PROBLEM TO BE SOLVED: To efficiently produce an inorganic sheet excellent in water impermeability and freeze damage resistance by performing waterproof treatment at press molding. SOLUTION: When a green sheet based on a hydraulic material is subjected to press molding in a mold and subsequently aged and cured to produce the inorganic sheet, a release agent, to which a waterproof resin is added, is applied to the surface of at least one surface of the green sheet and the mold before the green sheet is subjected to press molding.
