BLANK BOARD FOR INTERIOR TRIM OF VEHICLE AND ITS PRODUCTION

摘要

PURPOSE:To produce a blank board for interior trim of vehicle having high quality at a low cost by recycling a waste material of injection molded PP article containing a bumper edge material and to provide a process for the production of the board. CONSTITUTION:This blank board 2 is produced from virgin PP and pellets obtained by crushing a bumper edge material 13 (waste material of injection molded PP article) as main raw materials. The board has high quality and excellent strength and moldability and is producible at a reduced cost corresponding to the reduction of the amount of expensive virgin PP. Since the main raw material of the blank board is compounded with 5-40% of talc, the board has excellent characteristics such as high heat-resistance (free from deformation at 90 deg.C for 10hr), rigidity, easy moldability owing to elongation in the molding of interior trim of vehicle, resistance to cracking of the blank by impact at a low temperature and the uniform thickness in extrusion molding.
