Beschreibung
Zusammenfassung:	The invention discloses a polypropylene composition for chemical pipelines and a preparation method thereof, the composition is endowed with the characteristics, including excellent impact resistance, great chemical corrosion resistance, high heat resistance and heat deflection temperature, good long-term creeping property and extrusion processability and the like, by mixing beta nucleating agentsystem, antioxidant system and gray beta crystal promoting master batch with homopolymerized polypropylene which is generated by gas phase method as basic resin. The composition is mainly applied to manufacturing pipelines and can also be used for producing storage tank and pickling tank and for the transportation and the storage of chemical fluids, and the products thereof are extensively applied to industrial fields, such as electronics, medicines, chemical industry, food, semiconductor, steel, etc.
