Abstract
PURPOSE: To obtain a delustered thermoplastic resin sheet which is reusable, free of reglossing phenomenon when being subjected to vacuum molding, and useful for the interior of auto cars, etc., by a method in which a thermoplastic resin sheet is extruded, and shortly thereafter an inorganic powder is spread over the surface of the sheet and then the sheet is rolled and cooled between rolls in such a way as to bury the inorganic powder into the inside of the sheet.
CONSTITUTION: A thermoplastic resin sheet (e.g., polypropylene sheet, etc.) is extruded by an extruder. Shortly thereafter, an inorganic powder (e.g., silica powder, etc.) is spread over the surface of the molten sheet from a hopper, etc., whose bottom is provided with a screen and an electromagnetic vibrator, and then the sheet is rolled and cooled between plural rolls in such a way as to bury the inorganic powder into the inside of the sheet in order to obtain a sheet product. The rolls used include embossed rolls as well as flat rolls.
