摘要
PROBLEM TO BE SOLVED: To provide a process for producing, in good yield, sheet molding materials high in the content of a metal oxide and free from shrinkage upon heat-drying. ;SOLUTION: A process for producing a sheet molding material by forming an aqueous slurry obtained by dispersing (A) a metal oxide, (B) a synthetic resin, (C) fibrillated organic fibers, and (D) inorganic fibers into water into a sheet, dehydrating and heat-drying the sheet comprises adding a cationic flocculating agent (Ea) and an anionic flocculating agent (Eb) at the time of preparing said aqueous slurry.;COPYRIGHT: (C)2000,JPO
