Description
HDPE[MFR0.25g/10min(測定条件190℃,2.16kg)、密度0.949g/cm3]50重量部とLDPE[MFR1.79g/10min(測定条件190℃,2.16kg)密度0.918g/cm3]50重量部に再生材(上記HDPEとLDPEを主成分とする樹脂組成物の回収樹脂材料)を加えたものを混練し、これを原料樹脂として発泡ダクトをブロー成形により成形した。なお、原料樹脂ペレットには、リン系の酸化防止剤(チバ・ジャパン社製、商品名Irgafos168)、フェノール系の酸化防止剤(チバ・ジャパン社製、商品名Irganox1010)、主化学発泡剤(重曹:粒径64μm)、補助化学発泡剤(クエン酸)、無機粒子(タルクまたは炭酸カルシウム)、分散剤(金属石鹸:12−ヒドロキシステアリン酸マグネシウム)を練り込んだペレット(発泡補助材)を表1に示す使用量となるように配合した。 表1に、各成分の使用量(添加量)と作製された成形品の気泡径、発泡倍率を示す。
表1に示すサンプル2について、配合方法による相違を調べた。すなわち、酸化防止剤、無機粒子、主化学発泡剤、補助化学発泡剤及び分散剤の全てを含むペレットを原料樹脂ペレットに加えた場合と、各成分を個別に含むペレットを原料樹脂ペレットに加えた場合のそれぞれについて、同一条件で発泡成形を行い、得られた成形品の相違を調べた。その結果、酸化防止剤、無機粒子、主化学発泡剤、補助化学発泡剤及び分散剤の全てを含むペレットを原料樹脂ペレットに加えた場合には、気泡径や発泡倍率等にムラのない均質な成形品が得られた。これに対して、各成分を個別に含むペレットを原料樹脂ペレットに加えた場合には、各添加成分の分散等が不十分で、ムラのある成形品が得られた。
