Description
表2、表3、表4、表5に示すように、フィルムグレードのLLDPEとPP系樹脂を各配合割合で室温にてドライブレンドし、電線製造用押出成形機を使用し、上記樹脂組成物を導体径0.8mmの軟銅線上に厚み0.8mmで押出成形被覆し、被覆電線を製造した。高速押出成形速度は5m/分であった。
できあがった電線の表面性は、表面粗さ測定機(MITUTOYO製サーフテストSJ-301)を用いて算術平均粗さを測定することで比較した。
表2は、LLDPEとしてエボリューSP2320(プライムポリマー社:商標)とモアテック0138N(プライムポリマー社:商標)の2種類から、PP系樹脂としてBC3A、BC8A(日本ポリプロピレン株式会社)PB222A、VS200A、PM900A(サンアロマー社)の5種類から選択し、後者の0重量部配合と10重量部配合についてそれぞれ電線被覆用樹脂組成物を試験製造し、その押出成形被覆して得られた被覆電線の表面荒さを比較評価した結果である。
