Abstract
Description
ガラス長繊維強化熱可塑性高分子組成物を調製し、次いで、顆粒に切断した。その後、射出成形した検体について、等方性強さ、等方性弾性率および落下ダーツ衝撃などの性質を測定した。
30質量%のガラス繊維と様々な量の含浸剤(LOI)を含むいくつかのガラス長繊維強化ポリプロピレン組成物を、ポリマーマリトクスとしてMFIが45g/10分のSABIC(登録商標)PP579Sプロピレンホモポリマーを用いて製造した。このポリマーマリトクスは、40質量%のカーボンブラックのマスターバッチを1質量%、官能化ポリプロピレンを1質量%、および安定剤をさらに含んだ。
この実験は実施例1〜5と同様に行ったが、Performax(登録商標)507ガラス繊維(オーウェンス・コーニング社により供給された;19マイクロメートルの単繊維直径を有し、7質量%のサイズ剤成分を含有する)を用いて、30質量%のガラス長繊維強化ポリプロピレン組成物を製造し、含浸剤は使用しなかった。この実験は、欧州特許第0921919B1号明細書に記載されたプロセスを表している。ロービングを解くのが、時折不規則になるのが観察され、ストランドが互いにくっつき、繊維をワイヤコーティングユニットに案内するための部材が、べたつき、埃とガラス繊維の断片を取り込むのが見られた。また、被覆工程の前にストランド上に突出したカールした単繊維(毛羽)の群を生じる、ガラス単繊維の破壊が観察された。テストの結果が表1に示されている。
実施例1〜5と同様に、30質量%のガラス長繊維強化ポリプロピレン組成物を製造したが、ここでは、17マイクロメートルの直径の単繊維を含有する、タイプ30ロービングSE4121 2400Texガラス繊維を用いた。その結果が、表2に示されており、単繊維のより小さい直径には機械的性質にプラスの効果があり、最適な繊維分散(より高いガラス表面積に関連するようである)のためには、より多くの含浸剤が必要であることを示している。
実施例3を繰り返したが、ここでは、MFIが70g/10分(230℃/2.16kg)である「SABIC」PP513MNK10ポリプロピレン衝撃コポリマーに基づくポリプロピレン組成物をポリマーマリトクスとして用いた。表2に示された結果は、プロピレンコポリマーによると、ホモポリマーマトリクスと比べて、繊維の分散が良好になるが、機械的強さおよび剛性がいくぶん低くなることを表している。
