| description | The invention provides an anti-impact polypropylene alloy material and a preparation method thereof, the anti-impact polypropylene alloy material is prepared by adopting a method of periodically switching monomer composition, firstly, propylene homopolymerization is catalyzed by adopting a Ziegler-Natta catalyst, then propylene and butylene are copolymerized under the condition of periodically switching the monomer composition, a polypropylene alloy is prepared, and the anti-impact polypropylene alloy material is prepared. Wherein the mass content of polypropylene is 50-98%, the mass content of the propylene-butyl block copolymer is 1-40%, and the mass content of the propylene-butyl random copolymer is 1-10%. The impact strength of the polypropylene alloy provided by the invention is obviously higher than that of a polypropylene-butylene alloy prepared by a two-stage polymerization method under the same condition. According to the method provided by the invention, the content of the propylene-butyl block copo |
