PROBLEM TO BE SOLVED: To provide a polypropylene-based resin composition for blow molding, which is excellent in flame retardancy and suitable for forming a large blow molded body excellent in low specific gravity, rigidity, heat resistance, coatability and draw-down resistance, and to provide a flame-retardant blow molded body comprising the same.SOLUTION: A polypropylene-based resin composition for blow molding contains, on the basis of the total amount of the resin composition, 10-62 wt.% of a propylene/α-olefin block copolymer having an MFR of 0.05-2.5 g/10 min as a component (A), 10-25 wt.% of a propylene homopolymer having an MFR of 0.05-2.5 g/10 min as a component (B), 18-35 wt.% of a phosphate flame retardant as a component (C), 5-15 wt.% of a hydrogenation product of a styrene/conjugated diene block copolymer as a component (D), and 5-15 wt.% of an ethylene/α-olefin copolymer rubber having an MFR of 0.05-2 g/10 min as a component (E). A flame-retardant blow molded body comprises the polypropylene-based resin composition. |
