The present invention discloses a white high light blocking polypropylene material and its preparation method. The polypropylene material is prepared from a certain proportion of polypropylene resin, modified calcite, modified wollastonite, dispersant, and antioxidant as raw materials. The preparation method of the polypropylene material is as follows: S1. Add polypropylene resin, modified calcite, modified wollastonite, dispersant, and antioxidant into a mixer and mix at high speed; S2、 Add the mixed material to a twin-screw extruder for extrusion granulation to obtain the composite anti-static polypropylene material. The present invention uses modified calcite and modified wollastonite as shading aids, which not only improve the shading performance of polypropylene materials, but also have low prices, greatly reducing costs.
