The manufacturing method of an inorganic decorative board， and an inorganic decorative board

SUBJECT of the Invention The manufacturing method of the inorganic decorative board with which the sharp corrugated pattern was given to the surface by the deep-carving， and such an inorganic decorative board are provided. PROBLEM to be solved The manufacturing method of the inorganic decorative board 50 with which the corrugated pattern was formed in the surface is with moisture base-material formation process S1 which forms the plate-shaped moisture base material by which surface layer was comprised at least on the moisture mat|matte formed by wet sheet-forming from the slurry which contains a mineral fiber， an inorganic powdery substance， and binder as a main component， Drying process S2 which is made to dry the moisture base material and is used as a dry base material， Application|coating process S3 which apply|coats the softener consisting of water to the surface of a dry base material， Heating compression process S4 which carries out heating compression of the dry base material by an embossing die， hardens binder， and forms a corrugated pattern in the surface of a dry base material is provided after application|coating process S3. Surfactant is added to the softener apply|coated in application|coating process S3.
