This invention pertains to the field of polymer materials technology, disclosing a high-strength, low-haze transparent polypropylene material and its preparation method. By weight, the high-strength, low-haze transparent polypropylene material comprises: 85-95 parts random copolymer polypropylene, 8–12 parts of polymethyl methacrylate-modified microspheres, 2–5 parts of low-density polyethylene copolymer, 3–5 parts of compatibilizer, 0.2–1 part of antioxidant, 0.2–1 part of nucleating agent, and 1–3 parts of lubricant. The polymethyl methacrylate-modified microspheres are prepared via emulsion polymerization. poly(methyl methacrylate)-modified microspheres, low-density polyethylene, a compatibilizer, a dispersant, an antioxidant, a nucleating agent, and a lubricant. The modified polypropylene obtained through twin-screw extrusion granulation exhibits high strength, excellent transparency, and low haze. It can be widely used in daily transparent plastic products, medical devices, sanitary products, and other fields.
