Abstract

The invention discloses PP (polypropylene) filled masterbatch and a method for preparing the same. The PP filled masterbatch is prepared from the following components in parts by weight: 11-13 parts of PP resin, 50-70 parts of heavy calcium carbonate, 10-30 parts of precipitated barium sulfate, 1-3 parts of talcum powder, 1-1.5 parts of composite lubricant, 0.2-0.3 part of antioxidant, 3-5 parts of grafted PP/POE (polyethylene octene elastomer), 0.2-0.5 part of DCP (dicumyl peroxid), 0.2-1 part of titanate coupling agent and 0.2-1 part of sodium benzoate. The process for preparing the PP filled masterbatch is characterized by granulation through melt extrusion by a twin-screw extruder. The PP, the heavy calcium carbonate and the precipitated barium sulfate are blended together to prepare the PP filled masterbatch with excellent dispersibility. The PP filled masterbatch can be added and stirred to the PP to prepare the product with stable size and high specific surface area through the direct processing by an injecting-moulding machine.
