2.1 ウレタンを含むポリマーの生成についての記載-一般的記載
これより以下に特定される、以下の実施例ポリマー1~4は、処理長さ48D(12バレル)を有するZSK58 MC 2軸スクリュー押出し機(Coperion製)で生成した。ギアポンプを用いて、溶融物を押出し機から放出した。溶融物の濾過後、水中ペレット化を用いてポリマー溶融物をペレットへと処理し、これを加熱した流動床内で40~90℃で連続的に乾燥させた。
Ultradur B4500ポリブチレンテレフタレート(BASF SE製)を計量して第1のゾーンに入れた。PBTを溶融した後、モノマー性ジオール(例示的ポリマー1~4の-ブタン-1,4-ジオール)また他には低分子量ポリオール、さらに任意に触媒を、PBTのエステル交換のために第3のゾーンに供給した。エステル交換を行った後、さらなる反応成分、例えば、ジイソシアネートおよび長鎖ポリオールを第5のゾーンに加えた。上に記載されているようなさらなる添加剤の供給をゾーン8で実行する。
ポリエステル(PBT)は、処理長さ48Dを有するCoperionからZSK582軸スクリュー押出し機の第1のバレルに供給する。ポリエステルの溶融後、ポリオール、およびその中に存在するいずれかの触媒をバレル3に加える。エステル交換をバレル温度250~300℃で実行してから、ジイソシアネートを第5バレル内の反応混合物に加える。モル質量の増加をダウンストリームで、バレル温度190~230℃で実行する。合成後、得たポリマーを水中ペレット化またはストランドペレット化の対象下におき、続いて乾燥させる。
連結された溶融ポンプ、スクリーンチェンジャー付き起動弁、ダイプレートおよび水中ペレット化装置を備えた、スクリュー直径44mmおよび直径に対する長さの比42を有する2軸スクリュー押出し機を使用して、生成物(表1)で作製された膨張ビーズを生成した。熱可塑性ポリウレタンを乾燥してから、80℃で3時間処理して、0.02質量%未満の残留する含水量を得た。熱可塑性ポリウレタンに加えて、クロスリンカー1を一部の実験に加えた。
4.1 水蒸気融合による成形体の生成
膨張したペレットを続いて融合して、Kurtz ersa GmbH(Energy Foamer)製の成形機内で、水蒸気と接触させることによって、辺長200mmおよび厚さ10mmまたは20mmを有する正方形の厚板を得た。厚板の厚さに対して、融合パラメーターは冷却に関してのみ異なる。異なる材料に対する融合パラメーターは、型の可動側(MII)に面した最終成形物の厚板側が最小数の崩壊したビーズを有するように選択した。ギャップスチーミングもまた型の可動側を介して任意に実行した。実験に関わらず、型の固定側(MI)および可動側からの厚板厚さ20mmに対して冷却時間120秒および厚さ10mmの厚板に対して100秒を最後に常に確立した。表7は蒸気圧におけるそれぞれのスチーミング条件の一覧である。厚板は70℃で4時間オーブン内に保存する。
続いて、膨張したペレットは、高周波を用いて融合して、辺長200mmおよび厚さ10mmを有する正方形の厚板をKurtz ersa GmbH(RF Foamer)製成形機の中で得た。この目的を達成するために、およそ100gのビーズを秤量し、テフロン型内に配置し、できるだけ平坦に広げた。テフロンプレートで型を10mmに密閉し、膨張したペレットを圧縮成形した。24MHzでの高周波融合を開始し、設定電圧(設定ポイント値:5.9~6.5kV)に2秒で到達した。ビーズをこの電圧で30~50秒融合した。ビーズの照射の結果、型をおよそ100℃まで加熱した。続いて、外側を冷却せずに、型を室温で40~50℃に冷却してから、融合した厚板を除去した。機器パラメーターは表7に要約されている。厚板は、厚板を機械的に試験する前に、オーブン内で、70℃で4時間保存する。
