    • PURPOSE: A manufacturing method of a non-asbestos sheet is provided to obtain environmentally-friendly properties, dispersity and processability of a gasket sheet composition by mixing an opening-treated reinforcing fiber and inorganic filler without using an organic solvent. CONSTITUTION: A manufacturing method of a non-asbestos sheet comprises: a step of first primary mixing aramid fiber, glass fiber and kaolin in a tumbler; a step of secondary mixing the first mixture, acrylonitrile butadiene rubber, natural rubber, metal oxide and stearic acid in a kneader; a step third mixing the second mixture and a crosslinking agent in a roll mill; and a step of molding the third mixture into a sheet with the thickness of 1-2 mm. A manufacturing method of a non-asbestos gasket comprises a step of molding the non-asbestos sheet to a gasket in a high temperature and high pressure press.
