description The invention belongs to the technical field of polypropylene compositions, and particularly relates to a creep-resistant polypropylene composition and a preparation method thereof. The creep-resistant polypropylene composition is composed of the following components in parts by weight: 30-50 parts of homo-polypropylene; the polypropylene random copolymer is 49.1 to 69.85 percent; 0.05 to 0.3 part of an antioxidant 1; 0.05 to 0.3 part of an antioxidant 2; and 0.05 to 0.3 part of a light stabilizer. The mass flow rate of the homo-polypropylene melt is 0.2-2.0 g/10min, and the weight-average molecular weight of the homo-polypropylene melt is (40-70) * 10 < 4 >. The mass flow rate of the polypropylene random copolymer melt is 0.2 to 2.0 g/10min. The high-temperature-resistant and anti-yellowing plastic has good rigidity and toughness balance, especially outstanding high-temperature creep resistance and yellowing resistance, and can be used for production of products such as pipelines, valves and plates in a high
