Description
2.破砕された破片を粉碎機に投入してファイバー(Fiber)形態に粉砕し、打孔網を通過した粉砕物はスクリューコンベヤに押送されながらイルライト、ワックス、DOPとPE及びPP樹脂と共に攪拌混合されながら圧縮機に移送される。この際、粉砕物30〜50重量%、添加物5〜15重量%、PE及びPP樹脂30〜50重量%、イルライト1~5重量%の組成比で混合される。
3.圧縮機に移送された組成物を一定サイズに圧縮し、溶融機に移動後、溶融させて混合する。
4.溶融された混合物を押出機に入れてT−DIEで押出して1次成形し、1次成形された成形品をカレンダーの間を通過させて加圧して自動車内装材の基材層を成形する。
5.成形された基材層の両面に不織布を熱融着させて付着させ、形態とサイズによって裁断する。
