Thermoplastic resin composition for blow molding and molded article using the same

The invention relates to a thermoplastic resin composition for blow molding and a molded article using the same. The composition includes base resin and 0.1-3 parts by weight of inorganic particles (E), with the weight part of the base resin being 100 parts. Relative to the total weight of the base resin, the base resin includes 20-40% by weight of a dialkene type grafted copolymer (A), 10-20% byweight of an aromatic vinyl compound-vinyl cyanide compound copolymer (B), 30-50% by weight of an alpha-methyl styrene copolymer (C), and 10-20% by weight of N-phenyl maleimide copolymer (D). The inorganic particles (E) are zinc sulfide, titanium dioxide, talc or a combination thereof. 本发明涉及一种吹塑成型用热塑性树脂组合物及利用它而成的成型品，所述吹塑成型用热塑性树脂组合物包含基础树脂和相对于所述基础树脂100重量份为0.1～3重量份的无机粒子(E)，相对于所述基础树脂的总重量，所述基础树脂包含：20～40重量％的二烯烃类接枝共聚物(A)；10～20重量％的芳香族乙烯基化合物-氰化乙烯基化合物共聚物(B)；30～50重量％的α-甲基苯乙烯共聚物(C)；以及10～20重量％的N-苯基马来酰亚胺共聚物(D)，所述无机粒子(E)为硫化锌、二氧化钛、滑石或它们的组合。
