射出成形装置として横型トグル式射出成形機(宇部興産機械製 DP350射出成形機)を、熱可塑性樹脂としてポリプロピレン(三井化学(株)製 自動車内装グレード MRF30/ISO1133)を用いた。気泡核形成剤として酸化鉄の微粉末を、発泡性ガスとして空気を用い、可塑化シリンダ内の発泡剤含有溶融樹脂中に0.6MPaの圧力で注入した。可塑化スクリュは、スクリュ先端にミキシングヘッドを装着した2ステージスクリュを用いた。成形品は350×220mmの自動車内装品(グローブボックスアウター)で、充填時の金型キャビティ厚みが1.8mm、拡大後の厚みが3.6mm(容積拡大率2倍)を用いた。また、成形条件は樹脂温度200℃、金型温度30℃に設定した。成形品の評価は発泡セル密度状態及び外観状態を目視で行なった。実施例1で得られた成形品セル層の発泡状態は所望する気泡密度や気泡径を有した微細発泡セルの集合体であり、また、外観状態もスワルマークやシリバーストリークが少なく良好であった。そして、気泡核形成剤として酸化鉄の微粉末を、発泡性ガスとして空気を用いることから、成形時において有害な分解生成物が発生することもなく、従って、有害な分解生成物の残留がない熱可塑性樹脂の発泡成形品を得ることができた。
気泡核形成剤としてクエン酸の微粉末を、発泡性ガスとして二酸化炭素を用い(成形機、成形材料、成形品、スクリュ及び成形条件は実施例1と同様にした)、ポリプロピレン(三井化学(株)製 自動車内装グレード MRF30/ISO1133)にクエン酸の微粉末を2.5質量%混合した成形材料を成形機ホッパに供給し、二酸化炭素を可塑化シリンダ内の溶融樹脂中に0.6MPaの圧力で注入した。実施例2で得られた成形品セル層の発泡状態は所望する気泡密度や気泡径を有した微細発泡セルの集合体であり、また、外観状態もスワルマークやシリバーストリークが少なく良好であった。そして、気泡核形成剤としてクエン酸の微粉末を、発泡性ガスとして二酸化炭素を使用することから、成形時において有害な分解生成物が発生することがなく、従って、有害な分解生成物の残留がない熱可塑性樹脂の発泡成形品を得ることができた。
発泡性ガスとして高圧の二酸化炭素を用い(成形機、成形材料、成形品、スクリュ及び成形条件は実施例1と同様にした)、ポリプロピレン(三井化学(株)製 自動車内装グレード MRF30/ISO1133)を成形機ホッパに供給し、昇圧装置で加圧した二酸化炭素を可塑化シリンダ内の溶融樹脂中に10MPaの圧力で注入した。比較例1で得られた成形品のセル層は粗大な気泡が混在した発泡状態であり、また、外観状態はスワルマークやシルバーストリークが著しく、所望する気泡密度や気泡径を有した微細な発泡セルの集合体の射出発泡成形品を得ることができなかった。
