本発明のポリ塩化ビニル系樹脂成形品は、ポリ塩化ビニル系樹脂に、衝撃強度改質剤及び所定の平均1次粒子径を有する炭酸カルシウムを所定量含有するものである。
(1)ポリ塩化ビニル系樹脂コンパウンドの作製
全ての実施例に共通する信越化学工業社製のポリ塩化ビニル樹脂「TK−1000(平均重合度1000)」を使用し、所定の平均1次粒子径を有する炭酸カルシウム、衝撃強度改質剤、熱安定剤及び滑剤を、表1,2に示す配合材料及び配合量(質量部)で添加し、回転混合機として日本コークス工業社製10Lヘンシェルミキサー(FM10C/1型)を用いて、回転数1800rpm(但し、実施例14の回転数は2400rpm、実施例15の回転数は1200rpm)で回転混合させながら、0.1hrブレンドし、120℃でポリ塩化ビニル系樹脂コンパウンドを排出させた。なお、上記のヘンシェルミキサーには、上羽根としてST羽根(標準)、及び下羽根としてAO羽根(標準)をそれぞれ使用した。
上記で得たポリ塩化ビニル系樹脂コンパウンドを6インチ2本ロールにて、ロール温度170℃及び20rpmの条件でコントロールし、5分間混練し、厚み0.7mmのロールシート化した。
上記ロールシート(厚さ0.7mm)を所望の長さに切断し、所望の質量部となるように重ねあわせて180℃、圧力50kg/cm2及び5分の条件でプレスし、所望の厚さのプレスシートを得た。
ポリ塩化ビニル系樹脂コンパウンドの作製については、実施例1と同様に実施したが、予備溶融加工、本成形加工については、下記方法により押出成形品を作製した。
作製した粉体コンパウンドを用いて50mmφ単軸押出機にて押出ペレットを作成した。L/D=25の50mmφ単軸押出機にて、スクリュー圧縮比CR:2.5、スクリーン:♯60×1枚、スクリュー回転数:40rpm、シリンダー設定温度C1:140℃、C2:150℃、C3:155℃、C4:160℃(C1が最もホッパーに近く、その後C2、C3、C4の順に通過する)、ダイス設定温度160℃で押出ペレットを作成した。
作製した押出ペレットを用いて15mmφ異方向二軸押出機にて押出成形を行った。L/D=30の15mmφ異方向二軸押出機にて、スクリュー圧縮比CR:2.5、ダイス:4×10mm角棒、スクリュー回転数:40rpm、シリンダー設定温度C1:140℃、C2:150℃、C3:160℃、C4:170℃(C1が最もホッパーに近く、その後C2、C3の順に通過する)、ダイス設定温度180℃で押出成形を行った。
ポリ塩化ビニル系樹脂コンパウンドの作製については、実施例1と同様に実施したが、予備溶融加工を行わず、粉体コンパウンドを用いて実施例16と同様に本成形加工を実施した。
炭酸カルシウム及び衝撃強度改質剤を全く配合しないこと以外は、実施例1と同様に実施した。
炭酸カルシウムを全く配合しないこと及び塩素化ポリエチレン(衝撃強度改質剤)の配合量を表3に示すように変更した以外は、実施例1と同様に実施した。
衝撃強度改質剤を全く配合しないこと及び炭酸カルシウムの配合量を表3に示すように変更した以外は、実施例1と同様に実施した。
炭酸カルシウムの配合量及び塩素化ポリエチレン(衝撃強度改質剤)の配合量を表4に示すように変更した以外は、実施例1と同様に実施した。
炭酸カルシウムを全く配合しないこと及び衝撃強度改質剤の種類を表4に示すように変更した以外は、実施例1と同様に実施した。
炭酸カルシウムの配合量を表4に示すように変更し、10Lヘンシェルミキサー(FM10C/1型)の回転数を400rpmとした以外は、実施例1と同様に実施した。
JIS K 7111に準拠して、0℃±2℃の条件下でシャルピー衝撃試験を行い、衝撃強度を測定した。このシャルピー衝撃強度が20kJ/m2以上の場合を「○」、20kJ/m2未満の場合を「×」と評価した。その測定値及び評価を表1,2(実施例)及び表3,4(比較例)に併記した。
