Description
このため、これまで溶融混練押出機への水酸化マグネシウムを含む原料の供給速度は極端に低く設定され、かつ、溶融混練押出機内での吐出量も低く抑えることで、該押出機内での滞留時間を稼ぎ、この問題を解消していた。したがって、溶融混練押出機内での吐出量も低くなり、時間あたりの生産量はきわめて低く経済性に劣り、また押出機内での滞留時間も長くなるため樹脂や水酸化マグネシウムの熱的劣化も大きくなり、品質の低下が問題となっていた。
ポリアリーレンスルフィド樹脂(A)が30〜70質量部に対して、前記水酸化マグネシウム(B)が70〜30質量部の範囲であることを特徴とする。
かかる条件下に製造することによって前記ポリアリーレンスルフィド樹脂(A)をマトリックスとして前記水酸化マグネシウム(B)とを均一に分散させることができる。
表1、2に示す割合で各成分をドライブレンドした後、東芝機械株式会社製「TEM−58SS」二軸押出機を用い、シリンダー設定温度310℃で、吐出量Q(kg/hour)およびスクリュー回転数N(rpm)を表1に示す条件で原料供給して、溶融混練を行い、ペレットを製造した。次に、得られたペレットを140℃で3時間乾燥してから、試験片を成形し、各評価に供した。
23℃の環境下で、300mlのメスシリンダーに約200mlとなる水酸化マグネシウムを投入し、投入前後の質量差より投入した水酸化マグネシウムの重量W(g)を求めた。その後、東京理化機械製振盪機MMS−410型にて、8の字振盪を30回/分で1分振盪した後の水酸化マグネシウム上面のメニスカスを読み取り、水酸化マグネシウムの体積V(ml)を評価した。見掛け比重は以下の式で求めた。
(見掛け比重)=(W/V)
生産開始から生産停止となるまでの時間(分)で原料の供給安定性を評価した。ただし、「生産開始」とは、二軸押出機において、原料を二軸押出機に投入した時点を、また「生産停止」とは、スクリューを一定に回転させるためのモーター電流値が定格(80A)を超えて自動停止し、製造不能となった時点を言うものとする。
JIS−R2618「耐火断熱れんがの熱線法による熱伝導率の試験方法」に準拠し、ISO D2を組み合わせた120×60×20mm成形品の熱伝導率を測定した後、別途、JIS−R1611「セラミックスの熱拡散率測定」で、1mmt成形品を測定した場合との換算式を用い、測定値を換算し評価した。
JIS−K7171「プラスチック−曲げ特性の試験方法」に準拠。試験片はISOダンベル(4mmt)を射出成形にて成形し、流動方向の曲げ強さを評価した。
PPS:DSP. PPS H−1G (DIC株式会社製)
水マグ1:水酸化マグネシウム「キスマ5EU」(協和化学株式会社製)見かけ比重0.87
水マグ2:水酸化マグネシウム「マグシーズEP」(神島化学株式会社製)見かけ比重0.72
水マグ3:水酸化マグネシウム「マグシーズW」(神島化学株式会社製)見かけ比重0.64
水マグ4:水酸化マグネシウム「キスマ5E」 (協和化学株式会社製)見かけ比重 0.53
表3、4に示す割合で各成分をドライブレンドした後、東芝機械株式会社製「TEM−58SS」二軸押出機を用い、シリンダー設定温度310℃で、吐出量Q(kg/hour)およびスクリュー回転数N(rpm)を表1に示す条件で原料供給して、溶融混練を行い、ペレットを製造した。次に、得られたペレットを140℃で3時間乾燥してから、試験片を成形し、各評価に供した。
IEC112第3版に準拠。試験片はISO D3(3mmt)を射出成形により作成し、トラッキング破壊が生じる印加電圧を測定した。
JIS−K7171「プラスチック−曲げ特性の試験方法」に準拠。試験片はISO D2(2mmt)を射出成形にて成形し、所定試験片形状に切削加工後、TD方向の曲げ強さを評価した。
1.6mm厚みのスパイラルフロー金型を用い、シリンダー温度330℃、金型温度150℃、保圧80MPaで成形したときの流動長を測定した。
