Abstract
Description
そのため、上記不利点の少なくともいくつかを克服する難燃性PAN系繊維を製造するためのプロセスを開発することが望ましい。
・アクリレート−C1〜C12アルキル、アリールおよび環状アクリレート、例えばアクリル酸メチル、アクリル酸エチル、アクリル酸フェニル、アクリル酸イソボニル(isobonyl)
・メタクリレート−C1〜C12アルキル、アリールおよび環状メタクリレート、例えばメタクリル酸メチル、メタクリル酸エチル、メタクリル酸フェニル、メタクリル酸ブチル、メタクリル酸2−エチルヘキシルおよびメタクリル酸イソボニル(isobonyl)
・メタクリロニトリル。
・顔料:これらは一般に鉱物酸化物系顔料または有機顔料のいずれかであるが、他のものが当技術分野で知られている。それらは一般に約0.1〜1重量%で添加されるが、顔料の性質および所望の色濃度によって、他の濃度が適切である場合がある。
・可塑剤:これらは一般にコポリマと適合する液体である。好適な液体の範囲はコモノマの性質および割合によって変動し得る。有用な可塑剤としては、炭酸プロピレン、炭酸エチレン、ブチレンカーボネートおよびフタレート可塑剤が挙げられる。それらは一般的に、要求される可塑化の程度によって、コポリマの約40重量%まで(または30、20もしくは10%まで)の割合で使用される。
・潤滑剤:これらとしては界面活性剤、例えばポリエーテル系界面活性剤が挙げられ、コポリマの約2−3重量%までの割合で使用され得る。
・安定剤:これらは本明細書のどこかで記載され、コポリマの約0.1〜約1%の量で存在し得る。
・防火材料:これらは一般的に約2−3重量%までの割合で使用されるが、要求される追加の防火性の程度に依存する。好ましくは、防火材料はハロゲン化されていない。それらは鉱物、例えば水酸化アルミニウム、水酸化マグネシウムなど、および有機リン添加物、例えばトリフェニルホスフェートを含み得る。しかしながら、多くの場合、添加される防火剤は必要なく、使用されない。
・可燃性利点:溶融なしで炭化;
・熱安定性:加熱で、ステープルおよび糸の両方について収縮が全く、またはほとんどないことが必要である;
・溶融押出繊維:テクスチャー加工などのプロセスにとって好適である;
・繊維配向:溶融押出プロセスは、部分配向糸の形態の延伸繊維を生成させることができる;
・煙の低減:本発明の繊維は、従来のPANに比べて、炎源への曝露時に発する煙が少ない。本発明の耐火性PAN材料は、従来のPANに比べて、炎源への曝露時に溶融しない;
・着色性:本発明の繊維は容易に着色または染色することができる。特に、繊維生成中の染料および/または顔料の導入は、別個の染色工程の必要性を除去する;
・導電率:本発明の繊維は、生成中に導電性成分を添加することにより導電性にすることができる。
・耐熱性/防火性のための繊維
・高温公害防止排気濾過としての発電所および他の工業用排気システムのためのフィルタバッグのためのステープルファイバ
・編んで、織って織物にするための連続繊維または複合物のための練紡としての使用
・増強された熱特性を有するポリマフィルムまたはボードまたは中空繊維/チュービング
・建材−屋外/屋内/特殊ゾーンでの断熱用途
・複合または積層材料における耐火性繊維。
試薬
・溶媒:DMF100mL
・モノマ:アクリロニトリル(AN)(53.06g/mol)640mmol=33.96g

・開始剤AIBN(164.21g/mol)3.75mmol 616mg
・連鎖移動剤1−ドデカンチオール(202.40g/mol)0.375mmol=76mg
溶媒としての200mLのDMF、34g(640mmol)のAN、9.73g(113mmol)のMAのモノマ溶液を樹脂上で30分間撹拌し、阻害物質を除去し、それから、濾過した。重合を、凝縮器、ガラススターラー、窒素注入管、および溶媒損失を最小に抑えるために取り付けられた還流管が備えられた500mLの3つ口フラスコ中で実施した。溶液に乾燥窒素を15分間パージした。フラスコをそれから、下げて、65℃の油浴に6時間入れた。コポリマを、50倍過剰の脱イオン水からの沈殿により精製した。沈殿したポリマを濾過し、水、それからメタノールで洗浄し、真空下で70℃にて24時間の間乾燥させた。
グリセロール[20−40%wt]および/またはエチレングリコール[10−40%wt](合わせて<50%wt)を組み込んだ[40,000−90,000]の分子量の、AN/MA[85/15、90/10mol]のコポリマおよび好適な安定剤、例えばIrganox HP2225[0.1−1%wt]を、単一穴ダイまたはマルチフィラメント紡糸パックを有する16mm二軸式押出機に送り込んだ。加熱ゾーン160、170、190、190℃。押出フィラメントを巻き取りワインダで部分的に引き延ばし/配向させた。
