POLYPROPYLENE RESIN COMPOSITION FOR ROTATIONAL MOLDING WITH EXCELLENT HEAT RESISTANCE, RIGIDITY, IMPACT RESISTANCE, AND TRANSPARENCY, AND A ROTATIONALLY MOLDED PRODUCT MANUFACTURED FROM THE SAME

摘要

PURPOSE: A polypropylene resin composition is provided to have excellent mechanical properties and to improve the ability rigidity, impact resistance, heat resistance, and transparency of a rotationally molded product.;CONSTITUTION: A polypropylene resin composition comprises a polypropylene polymerized using 100.0 parts by weight of a Ziegler-Natta catalyst; 0.1-0.5 parts by weight of a UV stabilizer; and 0.05-0.5 parts by weight of a nucleating agent. The polypropylene resin composition has a melt index(230=, 2.16 kg) of 3-40g/10min and a molecular weight distribution(Mw/Mn) of 2-5. A manufacturing method of the polypropylene resin composition includes a step of polymerizing an olefin monomer under the presence of a catalyst. The catalyst is the Ziegler-Natta catalyst and the olefin monomer is propylene.;COPYRIGHT KIPO 2013
