Abstract

The invention belongs to the field of polypropylene modification, and particularly relates to a polypropylene composition and a preparation method thereof. The polypropylene composition provided by the invention is prepared from the following raw materials in parts by weight: 100 parts of polypropylene resin, 0.05-2% of heat stabilizer, 0.02-0.5 part of stearic acid metal salt, 0.05-3 parts of inorganic filler and 0.01-0.2 part of organic nucleating agent. The polypropylene resin composition, which is prepared by blending and granulating the polypropylene resin, heat stabilizer, stearic acid metal salt, inorganic filler and slight nucleating agent, has the advantages of high rigidity, high heat resistance and low cost; the preparation technique is simple and easy to implement; and the polypropylene resin composition can be used in the fields of automobiles, home appliances, home furnishing and the like.

Description

technical field [0001] The invention belongs to the field of polypropylene modification, and in particular relates to a polypropylene composition and a preparation method thereof. Background technique [0002] Polypropylene resin is gradually replacing some engineering plastics due to its excellent rigidity and heat resistance, and rich post-modification methods, and is widely used in automobiles, home appliances and households. Especially the impact copolymer polypropylene resin, due to the progress of production technology and catalyst technology, has endowed the product with more excellent comprehensive performance. However, due to the high technical difficulty in the production of impact copolymer polypropylene, especially in terms of product rigidity, toughness and fluidity, it cannot fully meet the needs in some fields, so it is still necessary to develop impact copolymer polypropylene. Post-modification is carried out on the basis of grades, that is, high rigidity, h...
