| description | The invention belongs to the technical field of high polymer materials, and particularly relates to a high-gloss polypropylene composition and a preparation method thereof. The impact-resistant polypropylene composite material is prepared from the following raw materials in parts by mass: 100 parts of impact-resistant co-polypropylene, 0.1 to 0.2 part of an antioxidant A, 0.05 to 0.2 part of an antioxidant B, 0.03 to 0.5 part of a nucleating agent, 0.03 to 0.1 part of boron nitride and 0.03 to 0.2 part of diester phthalate, wherein the mass flow rate of the anti-impact co-polypropylene melt is 8-20g/10min, the molecular weight distribution is 4.5, the Mn is 5,000,000, the Mw is 2,000,000-2,000,000, the MZ is 8,000,000, and the MZ + 1 is 1,9,000,000; the content of ethylene is 2.5 to 4.0 percent; the crystallinity is 66-73%, the beta crystal content is 1-3.0%, and the beta crystal size is 16-17.5 nm; and the isotacticity is 89 to 91.6. The composition is high in glossiness and good in toughness, and the prepar |
