Description
面方向にわたって所定間隔に離間された状態で積層された上記各板状金属体の間に、融点がT1の絶縁性ポリマで構成される第1シート材を配置し、最外に位置する各板状金属体の外側に、融点がT2(<T1)の絶縁性ポリマで構成される第2シート材を重ねて配置し、それらの各板状金属体、第1シート材、及び第2シート材で構成される積層体に、T2より高く、かつ、T1より低い温度で加熱加圧成形処理を施し、各板状金属体間の間隔を第1シート材で確保しつつ、第2シート材を溶融させ、各板状金属体及び第1シート材の周りを、融点がT2の絶縁性ポリマで構成されるモールド部で覆うものである。
一方、スチレンブロックを有するスチレン系エラストマとしては、例えば、スチレン−エチレンブチレン−スチレン共重合体(SEBS)、スチレン−エチレンプロピレン−スチレン共重合体(SEPS)、スチレン−ブチレン−スチレン共重合体(SBS)などのトリブロック共重合体、水添したスチレン−ブタジエンゴムなどのジブロック共重合体、などが挙げられる。
図1に示したように、両面に熱硬化型接着層を塗布形成したPPEシート(旭化成(株)製、ザイロン540Z、厚さtが0.4mm)を準備し、2枚の銅板のラップ領域より縦横が10mm大きいサイズ(220mm×230mm)に切断した。また、図2に示したように、片面にホットメルト接着剤層を塗布形成した難燃PE樹脂シート(宇部興産(株)製、Z555、厚さtが2.5m)を準備し、2枚の難燃PE樹脂シートの体積が、240mm×250mm×5mmのモールド成形体の体積から銅板及びPPEシートの体積を引いた値よりも大きくなるように、難燃PE樹脂シートを切断形成した(220mm×230mm×2.5mm)。さらに、図8に示した下金型81と、この下金枠81と一対の上金枠で構成される枠体を準備した。
枠体として図10に示した射出成形金型110を準備した。
