Description
以下、本発明にもとづくポリプロピレン樹脂組成物を、それぞれに構成成分にもとづいてより詳細に説明する。
本発明の組成物に含まれるポリプロピレン樹脂（Ａ）は、シンジオタクチック・ホモポリプロピレン、アイソタクチック・ホモポリプロピレン、プロピレン−エチレン・ブロック・コポリマー、およびプロピレン−エチレン・ランダム・コポリマーを含むものである。プロピレン−エチレン・ブロック・コポリマーおよびプロピレン−エチレン・ランダム・コポリマーが好ましい。アイソタクチック・ホモポリプロピレンの中では、１３Ｃ−ＮＭＲ（核磁気共鳴）スペクトルによって識別されたアイソタクチックペンタッドフラクション０．８０〜０．９９、好ましくは０．９０〜０．９９、を有する結晶性ポリプロピレンを使用することが好ましい。プロピレン−エチレン・ランダム・コポリマーの中では、機械的性質および押し出し処理性を考慮して、室温で２〜１０ｋｇ・ｃｍ／ｃｍのアイゾット衝撃強度を有するランダム・コポリマーを使用することが好ましい。プロピレン−エチレン・ブロック・コポリマーの中では、機械的性質、押し出し処理性、成形性、衝撃抵抗、等々を考慮して、室温で１１ｋｇ・ｃｍ／ｃｍ以上、より好ましくは５０ｋｇ・ｃｍ／ｃｍ以上のアイゾット衝撃強度を有するインパクト・コポリマーを使用することが好ましい。本発明にもとづいて使用されるポリプロピレン樹脂は、樹脂の種類の如何にかかわらず、メルト・インデックス（ＡＳＴＭ Ｄ１２３８：２３０℃、負荷２．１６ｋｇ）０．１〜６０ｇ／１０分を示さなければならない。ポリプロピレン樹脂のメルト・インデックスが０．１ｇ／１０分未満であると、樹脂組成の射出成形性が十分でなく、フロー・マークなどの外観上の欠陥が生じる。他方、ポリプロピレン樹脂のメルト・インデックスが６０ｇ／１０分を超えると、樹脂組成の射出成形性はすぐれたものとなるが、押し出し成形性が十分でなく、また耐衝撃性が著しく低下する。
Hereinafter, the polypropylene resin composition based on this invention is demonstrated in detail based on each component.
The polypropylene resin (A) contained in the composition of the present invention contains syndiotactic homopolypropylene, isotactic homopolypropylene, propylene-ethylene block copolymer, and propylene-ethylene random copolymer. Propylene-ethylene block copolymers and propylene-ethylene random copolymers are preferred. Among isotactic homopolypropylenes, crystals having an isotactic pentad fraction of 0.80 to 0.99, preferably 0.90 to 0.99, identified by 13C-NMR (nuclear magnetic resonance) spectra. It is preferable to use a conductive polypropylene. Among the propylene-ethylene random copolymers, it is preferable to use a random copolymer having an Izod impact strength of 2 to 10 kg · cm / cm at room temperature in consideration of mechanical properties and extrusion processability. Among propylene-ethylene block copolymers, in view of mechanical properties, extrusion processability, moldability, impact resistance, etc., 11 kg · cm / cm or more, more preferably 50 kg · cm / cm or more at room temperature. It is preferred to use an impact copolymer having Izod impact strength. The polypropylene resin used in accordance with the present invention must exhibit a melt index (ASTM D1238: 230 ° C., load 2.16 kg) 0.1-60 g / 10 min, regardless of the type of resin. When the melt index of the polypropylene resin is less than 0.1 g / 10 minutes, the resin composition has insufficient injection moldability and appearance defects such as flow marks occur. On the other hand, when the melt index of the polypropylene resin exceeds 60 g / 10 minutes, the injection moldability of the resin composition is excellent, but the extrusion moldability is not sufficient, and the impact resistance is remarkably lowered.
