发明名称 METHOD FOR PREPARING A CERAMIC-FORMING PREPREG TAPE
摘要 A tacky, drapeable, ceramic-forming sheet is prepared by (a) dispersing in water a ceramic-forming powder and a fiber, (b) flocculating the dispersion by adding a cationic wet strength resin and an anionic polymer, (c) dewatering the flocculated dispersion to form a sheet, (d) wet pressing and drying the sheet, and (e) coating or impregnating the sheet with a ceramic-forming adhesive that is a polymeric ceramic precursor, or a dispersion of an organic binder and the materials used to form the sheet. The sheets can be stacked on top of one another to form laminates, which are then fired to consolidate the sheets to a ceramic.
