Abstract
The invention relates to a polypropylene polymer and a preparation method thereof. The preparation method comprises the following steps: mixing 500 to 800 weight portions of polypropylene, 100 to 300 weight portions of nanometer filler, 50 to 200 weight portions of fire retardant, 1 to 10 weight portions of antioxidant, 1 to 5 weight portions of nucleator, 1 to 5 weight portions of dispersant and 0 to 10 weight portions of other additives in a high speed mixing machine for 2 to 5 minutes to prepare a pre-mixture; and then carrying out the melted extrusion and granulation of the pre-mixture through a double screw extruder, and adding the common additives during the processing if required. Compared with the prior art, the polypropylene polymer is characterized by high scratch resistance, high gloss, fire retardation, and the like.
Description
Technical field
The present invention relates to the chemical composition technical field, relate in particular to scratch resistance wound, high gloss, flame-proof polypropelene composition and preparation method thereof.
