Description
金属板としては、厚さ0.6mmの溶融亜鉛メッキ鋼板(GI)を使用した。プラスチック層は、ポリプロピレン(PP)80重量%及び熱可塑性ポリエステルポリエーテルエラストマー(TPEE)20重量%を溶融混合した後、圧出して厚さ0.5mmで製造した。この時、熱可塑性ポリエステルポリエーテルエラストマーは、ポリブチレンテレフタレート30重量%及びポリテトラメチレンエーテルグリコール70重量%を含む原料組成物から製造した。準備された溶融亜鉛メッキ鋼板及び製造されたプラスチック層を、ホットプレス装置を利用して220℃の温度及び100kgf/cm2の圧力条件で熱圧搾することで、鋼板とプラスチック層を一体化した。
金属板としては、厚さ0.8mmの溶融亜鉛メッキ鋼板(GI)を使用し、プラスチック層を製造するとき、熱可塑性ポリエステルポリエーテルエラストマー(TPEE)を使用せず、その代わりにポリプロピレン(PP)のみを使用したこと以外は、実施例1と同様に製造した。
プラスチック層を製造するとき、熱可塑性ポリエステルポリエーテルエラストマー(TPEE)を使用せず、その代わりにポリビニルブチラール(PVB:Poly Vinyl Butyral)を使用したこと以外は、実施例1と同様に製造した。
1.振動減殺試験
実施例1、比較例1及び比較例2で製造した2層構造のラミネート(Laminate)鋼板に対して振動減殺試験を実行した。試験は、図2に示したように、直径3mmのホール(hole)を有するサイズ95×30mmの試験片(specimen)に対して、インパクトハンマー(PCB Piezotronics model No.086E80 impact hammer)及び加速度センサー(B&K type 4373 acceleration sensor)を利用して実行した。加振力は、50Nを付与した。表で、1次モードは、1次固有振動数での振動を測定したものであり、2次モードは、2次固有振動数の条件で実行したものである。
金属板としては、厚さ0.3mmの溶融亜鉛メッキ鋼板(GI)2枚を使用した。プラスチック層は、表2のように、ポリプロピレン(PP)及び熱可塑性ポリエステルポリエーテルエラストマー(TPEE)の含量を変化させて溶融混合した後、圧出して厚さ0.5mmで製造した。この時、熱可塑性ポリエステルポリエーテルエラストマーは、ポリブチレンテレフタレート30重量%及びポリテトラメチレンエーテルグリコール70重量%を含む原料組成物から製造した。準備した2枚の溶融亜鉛メッキ鋼板及び製造されたプラスチック層を、ホットプレス装置を利用して220℃の温度及び100kgf/cm2の圧力条件で熱圧搾することで、プラスチック層20が中間に配置されてプラスチック層20の上部と下部に金属板10が積層されたサンドイッチ構造とした。
プラスチック層を製造するとき、熱可塑性ポリエステルポリエーテルエラストマー(TPEE)を使用せず、その代わりにポリプロピレン(PP)のみを使用したこと以外は、実施例2と同様に製造した。
プラスチック層を製造するとき、ポリプロピレン(PP)及び熱可塑性ポリエステルポリエーテルエラストマー(TPEE)を使用せず、その代わりにポリエチレンテレフタレート(PET)のみを使用したこと以外は、実施例2と同様に製造した。
プラスチック層を製造するとき、ポリプロピレン(PP)及び熱可塑性ポリエステルポリエーテルエラストマー(TPEE)を使用せず、その代わりにナイロン6、6のみを使用したこと以外は、実施例2と同様に製造した。
プラスチック層を製造するとき、熱可塑性ポリエステルポリエーテルエラストマー(TPEE)を使用せず、その代わりにポリビニルブチラール(PVB)を表2のように含量を変化させて使用したこと以外は、実施例2と同様に製造した。
2.密着力試験
実施例2〜実施例7及び比較例3〜比較例12で製造した3層構造のサンドイッチ構造に対して密着力試験を実行した。試験は、図4に示したように、横25×縦255×厚さ1.1mmの試験片(specimen)に対して、重ね剪断(Lap shear)テストを実行した。具体的に、引張速度50mm/分及びロードセル(Load cell)50kNの条件で実行してせん断強度を測定した。
