Zusammenfassung: | To provide a thermoplastic resin composition capable of providing a molding which is excellent in low glossiness and low image clarity and has good molding appearance, a method for producing the same, and a molding.SOLUTION: A thermoplastic resin composition contains a component (A): a thermoplastic resin, a component (B): one or more selected from the group consisting of acid group-modified rubber, an acid group-modified graft, an acid group-modified acrylonitrile-styrene copolymer, epoxy-modified rubber, an epoxy-modified graft, and an epoxy-modified acrylonitrile-styrene copolymer, and a component (C): at least one of a crosslinked hard resin having an average particle diameter of 2-35 μm and inorganic particles having an average particle diameter of 2-35 μm. A content of the component (A) is 40-90 mass% with respect to the total mass of the thermoplastic resin composition, the total of the contents of the component (B) and the component (C) is 10-60 mass% with respect to the total mass of the thermoplastic resin composition, and a mass ratio represented by the component (B)/the component (C) is 0.1-10.SELECTED DRAWING: None
【課題】低光沢性及び低写像性に優れ、成形外観が良好な成形品が得られる熱可塑性樹脂組成物及びその製造方法と、成形品を提供する。【解決手段】(A)成分:熱可塑性樹脂と、(B)成分:酸基変性ゴム、酸基変性グラフト、酸基変性アクリロニトリル−スチレン共重合体、エポキシ変性ゴム、エポキシ変性グラフト、エポキシ変性アクリロニトリル−スチレン共重合体からなる群より選ばれる1種以上と、(C)成分:平均粒子径が2〜35μmである架橋硬質樹脂及び平均粒子径が2〜35μmである無機粒子の少なくとも一方と、を含む、熱可塑性樹脂組成物であって、(A)成分の含有量が、熱可塑性樹脂組成物の総質量に対して40〜90質量%であり、(B)成分及び(C)成分の含有量の合計が、熱可塑性樹脂組成物の総質量に対して10〜60質量%であり、(B)成分/(C)成分で表される質量比が0.1〜10である、熱可塑性樹脂組成物。【選択図】なし |
