Abstract
A polypropylene composition, a preparation method thereof, and a film or a sheet prepared from the polypropylene composition and use thereof. The composition includes 45 parts to 75 parts of a polypropylene, 10 parts to 35 parts of an elastomer, 5 parts to 20 parts of a polyethylene, 0.1 parts to 0.5 parts of an antioxidant, and 0.1 parts to 0.5 parts of a lubricant. A half peak width of a crystallization peak of the polypropylene is 5° C. to 10° C., and a peak temperature of the crystallization peak of the polypropylene is 105° C. to 115° C. The polypropylene composition has a good tenacity, especially a−30° C. low-temperature impact performance. The film or the sheet prepared from the composition and applied to automotive interior parts, can enable the external accessories not only to be less likely to generate sharp fragments while being strongly impacted, but also to have a matte characteristic.
