PA−6:ポリアミド6、種類K122、粘度数115ml/g(ISO307に準拠し測定)(オランダ国のDSM(DSM,The Netherlands)から)
PA−4,6:ポリアミド−4,6、種類KS200、粘度数160ml/g(ISO307に準拠し測定)(オランダ国のDSMから)
GF−I:ガラス繊維強化剤:ポリアミド−6に使用される標準的な種類のガラス繊維
GF−II:ガラス繊維強化剤:ポリアミド−46に使用される標準的な種類のガラス繊維
AADS:補助添加剤:潤滑剤付加物(annex)離型剤、CuI/KI安定剤、ピグメントコンセントレート、担体ポリマー、および相溶化剤を含む標準的な添加剤の組合せ
ICA:鉄含有添加剤:平均粒度30μmの鉄単体粒子20質量%をPE中に含むマスターバッチ
[比較実験A:PA−6−GF]
30重量%のガラス繊維で強化されたPA−6−1−GFを、PA−6およびGFから、バレル温度260℃、スクリュー回転数250rpmのZSK30型二軸押出機内で配合した。
30重量%のガラス繊維で強化されたPA−4,6−GFを、PA−4,6およびGF−IIならびに通常の加工助剤および安定剤から、バレル温度300℃、スクリュー回転数275rpm(処理量20Kg/h)のZSK25押出機内で配合した。
ポリアミド−6およびポリアミド−46(質量比25/75)、ガラス繊維GF−II、通常の加工助剤および安定剤、ならびに鉄単体のマスターバッチ2.5質量%を、比較実験Bと同一条件でZSK25二軸押出機内において配合することにより、35重量%のガラス繊維で強化された、鉄含有添加剤で改質されたポリアミド−6/46の組成物を作製した。
ポリアミド−6およびポリアミド−46(質量比50/50)、ガラス繊維GF−II、通常の加工助剤および安定剤、ならびに鉄単体のマスターバッチ2.5質量%を、比較実験Bと同一条件でZSK25二軸押出機内において配合することにより、40重量%のガラス繊維で強化された、鉄含有添加剤で改質されたポリアミド−6/46の組成物を作製した。
試験に供したすべての材料を、以下の条件に従い、寸法120mm×120mm×4mmの板に射出成形した。
比較実験Aのポリアミド−6材料の射出成形を、バレル温度の設定を230〜260℃、金型温度を80℃として、KM120射出成形機で実施した。
実施例I〜IIおよび比較実験Bのポリアミド−4,6およびポリアミド−6/4,6材料の射出成形を、バレル温度の設定を300〜310℃、金型温度を120℃として、KM120射出成形機で実施した。
Bielomatik(独国ノイヘン(Neuffen,Germany))K3210型振動溶着機を用いて溶着試験を実施した。溶着条件を以下に示す:周波数:240Hz;振幅:0.9mm;溶着圧:2Mpa;溶着時間:4秒間;保圧時間:7秒間。この工程を時間制御することにより、推定で1.8mmの溶着深さが得られるようにした。各材料について4回の溶着を実施した。
突合せ溶着した試料を幅10mmの引張試験片に切断し、Zwick試験機を用い、クロスヘッド速度を10mm/minとして、破損に至るまで荷重をかけた。引張強さを、溶着面積すなわち4mm×10mmに標準化された破壊時点の力として得た。エクステンシオメーター(extensiometer)で歪みを測定し、巨視的な破壊歪みと定めた(多くの場合、実際の歪みはこれよりもはるかに高い可能性がある)。列挙した値は4つの試験片の平均値である。
上述した方法に従う振動溶着を、表Iに列挙した材料の組合せについて実施した。上述の方法に従い、溶着された材料について引張試験を実施した。試験結果を表Iに報告する。
