Title
(EN) POLYPROPYLENE-BASED RESIN COMPOSITION
(FR) COMPOSITION DE RÉSINE À BASE DE POLYPROPYLÈNE
(JA) ポリプロピレン系樹脂組成物
Abstract
(EN) This polypropylene-based resin composition contains 15-65 wt% of a propylene random copolymer (A'), 3-40 wt% of a propylene polymer (A) having a melt peak temperature at 160°C or higher in a melting curve measured using a differential scanning calorimeter, 10-35 wt% of an ethylene-α-olefin copolymer (B), 20-30 wt% of glass fibers (C), and 0.1-5 wt% of an acid-modified polyolefin (D). The composition also contains, with respect to 100 parts by weight thereof, 0.01-1 parts by weight of a nucleating agent (E) represented by general formula (I). Provided is a polypropylene-based resin composition from which a molded article having excellent scratch resistance can be obtained efficiently (at a short molding cycle).
(FR) L'invention concerne une composition de résine à base de polypropylène qui contient, pour 100 parties en poids d'une composition contenant: 15% en masse à 65% en masse d'un copolymère aléatoire (A') de propylène; 3% en masse à 40% en masse d'une copolymère (A) de propylène dont la température de pic de fusion d'une courbe de fusion telle que mesurée par analyse calorimétrique différentielle est supérieure ou égale à 160℃; 10% en masse à 35% en masse d'un copolymère (B) éthylène-α-oléfine; 20% en masse à 30% en masse de fibres (C) de verre; et 0,1% en masse à 5% en masse d'une polyoléfine (D) modifiée par un acide; 0,01 partie en poids à 1 partie en poids d'un agent (E) de nucléation représenté par la formule générale (1). Cette composition de résine à base de polyoléfine permet d'obtenir efficacement (avec un cycle de moulage court), un corps moulé excellent en termes de résistance aux rayures.
(JA) プロピレンランダム共重合体(A')が15重量%以上65重量%以下と、 示差走査熱量測定計を用いて測定した融解曲線の融解ピーク温度が160℃以上のプロピレン重合体(A)が3重量%以上40重量%以下と、 エチレン-α-オレフィン共重合体(B)が10重量%以上35重量%以下と、 ガラス繊維(C)が20重量%以上30重量%以下と、 酸変性ポリオレフィン(D)が0.1重量%以上5重量%以下とを含有する組成物100重量部に対し、 下記一般式(I)で表される造核剤(E)が0.01重量部以上1重量部以下とを含有するポリプロピレン系樹脂組成物。 耐傷付き性に優れる成形体を、効率よく(短い成形サイクルで)得ることができるポリプロピレン系樹脂組成物を提供する。
