Description
当該技術分野で公知の種々のタイプのいずれかの発泡体も、本発明の方法を使用し、本発明に従って1種または2種以上の芳香族二酸エステルジオール(および/又はそれらの置換カルバメート)が加えられた典型的なポリウレタン調合物を使用して作られるであろう。例えば、本明細書に記載された優れた経時特徴を有する軟質ポリウレタン発泡体は、典型的には、下の表1内に示す量の成分を含む。表1に示す成分は、後で下に詳細が記載される。
本発明の組成物中の触媒は、非遊離性の第3級アミンを含む。本願で用いるように、“非遊離性第3級アミン”の語は、第1級アミン、第2級アミン、ヒドロキシル基、アミドもしくはウレア等のイソシアネート反応性基を含む第3級アミン、または(典型的には、120℃より上の)高沸点を有する第3級アミンをいう。いずれの場合でも、結果としていくらかあるいは全ての触媒が発泡体内に残留する。本願で用いるように、“発泡体に残留する”第3級アミン触媒への言及は、それが発泡体中のいかなる他の成分またはその出発材料と反応しているか否かによらず、いかなる形でも残留する触媒を含む。
ポリウレタンは、ポリオール(典型的には、ポリオールの混合物である)中のヒドロキシル基と、有機イソシアネートとの反応によって製造される。本発明の目的のためには、“ポリオール成分”の語は、エステルを含まないポリオールのみを含み、トレース量以外のエステルは存在しないという意味である。したがって、例えば、ポリエステルポリオールは、本発明に従う“ポリオール成分”の一部ではない。
重合時にポリウレタンマトリックス中にボイドを生成する発泡剤を含ませることによって、ポリウレタン発泡体の生成を補助してもよい。当該技術分野で公知のあらゆる発泡剤が使用されてもよい。好適な発泡剤は、発熱重合反応の間に蒸発する低沸点を有する化合物を含む。そうした発泡剤は一般的に不活性であり、したがって重合反応の間に分解または反応しない。不活性発泡剤の例は、二酸化炭素、クロロフルオロ炭素、水素化されたフルオロ炭素、水素化されたクロロフルオロ炭素、アセトン、およびシクロペンタン、イソペンタン、n−ペンタン、およびそれらの混合物等の低沸点炭化水素を含むが、これらに限られない。他の好適な発泡剤は、イソシアネート化合物と反応してガスを発生する化合物、例えば水を含む。
他の追加成分
顔料は、製造の間のポリウレタン発泡体をカラーコード化するために使用されてもよい、例えば生産物の等級を識別するため、または黄色化を隠すために使用されてもよい。顔料は、ポリウレタンの技術分野で公知のあらゆる好適な有機または無機顔料を含んでもよい。例えば、有機顔料または着色剤は、アゾ/ジアゾ染料、フタロシアニン、ジオキサジン、およびカーボンブラックを含むがこれらに限られない。無機顔料の例は、チタニウムジオキサイド、酸化鉄、または酸化クロムを含むがこれらに限られない。
遊離性対非遊離性触媒を使用した先行技術の処方
32オンス(951ml)紙コップ中の約302gの前混合物(表2の様に調製された)に第3級アミン触媒を加えることによって発泡体パッドを調製した。処方物を、2インチ(5.1cm)直径の攪拌パドルを付けたオーバーヘッド攪拌機で、約6,000RPM約10秒間混合した。
2)コポリマー化スチレンおよびアクリロニトリル、ベースポリオール分子量約4800を含むグラフト化ポリエーテルポリオール、MIミッドランドのダウケミカル社から入手可能。
3)シリコーン界面活性剤、エアープロダクツアンドケミカルズ社から入手可能。
発泡体パッドを、比較実施例2と同じ手順および同じ非遊離性の触媒が使用して作ったが、これらの例では芳香族二酸エステルジオールを、ポリオール前混合物に加えた。実施例3のために、標準および商業的に入手可能なポリエステルポリオール(PEP、NCワシントンのインビスタ社(Invista)から商標名TERATE(商標)2540で販売される)を加え、実施例4では、同じPEPを加えたが、より高い充填量レベル(2.0PPHP)であった。TERATE(商標)2540ポリオールは式(I)に従うテレフタル酸およびジエチレングリコールから誘導された芳香族二酸エステルジオールを含む。
非遊離性触媒と組み合わせた他のエステル
本発明の芳香族二酸エステルジオール(および/又はそれらの置換カルバメート)の代わりに、種々の量の他のエステルを使用して、発泡体パッドを上記の様に調製した。発泡体パッドテストの結果が下の表4に示される。
