Description
[0002]本発明は、1,1,1,4,4,4-ヘキサフルオロブテン(1336mzzm)及び1-クロロ-3,3,3-トリフルオロプロペン(1233zd)の混合物に関する。より詳しくは、本発明は1,1,1,4,4,4-ヘキサフルオロブテン及び1-クロロ-3,3,3-トリフルオロプロペンを含む発泡剤組成物に関する。
かかる化合物の多くに関連するオゾン破壊性のために一般的には人気を失なっている。したがって、発泡用途のための代替物を提供する新規なフルオロカーボン及びヒドロフルオロカーボン化合物、並びに既存の組成物のブレンドに対する増加する必要性が存在する。大気温度よりも高い沸点を有する発泡剤は、特徴として劣った低温熱的性能を有する。したがって、理想的な発泡剤又は発泡剤ブレンドは、広い温度範囲にわたって最適の性能を有するLGWP材料でなければならない。
異性体を含み、これは単独か又はトランス異性体との混合物で与えることができる。このため、1336mzzmは、約50重量%~約100重量%のシス異性体及び約0重量%~約50重量%のトランス異性体;約75重量%~約100重量%のシス異性体及び約0重量%~約25重量%のトランス異性体;或いは約90重量%~約100重量%のシス異性体及び約0重量%~約10重量%のトランス異性体;を含んでいてよい。
[0013]1-クロロ-3,3,3-トリフルオロプロペンは、同様にここで議論する所望の効果を達成する任意の有効量で与えることができる。一態様においては、かかる有効量は約30~約95モル%である。更なる態様においては、かかる有効量は、約30~約70モル%;約40~約60モル%;又は約50モル%である。1-クロロ-3,3,3-トリフルオロプロペンは任意の異性体又は複数の異性体の混合物として与えることができるが、ここで定義するように、一態様においては、本組成物は少なくとも1233zdのトランス異性体を含み、これは単独か又はシス異性体との混合物で与えることができる。このため、1233zdは、約50重量%~約100重量%のトランス異性体及び約0重量%~約50重量%のシス異性体;約75重量%~約100重量%のトランス異性体及び約0重量%~約25重量%のシス異性体;或いは約90重量%~約100重量%のトランス異性体及び約0重量%~約10重量%のシス異性体;を含んでいてよい。
が本発明の広い範囲内である。更に、本発明の組成物は、共沸混合物、共沸様混合物、又は非共沸混合物であってよい。幾つかの態様においては、本組成物は、約5~約70モル%の1336mzzm及び約30~約95モル%の1233zdを含む。更なる非限定的な態様においては、本組成物は、約30~約70モル%の1336mzzm及び約30~約70モル%の1233zd;約40~約60モル%の1336mzzm及び約40~約60モル%の1233zd;或いは約50モル%の1336mzzm及び約50モル%の1233zd;を含む。
ェニルイソシアネート、特に約30~約85重量%のメチレンビス(フェニルイソシアネート)を含み、残部として2より大きい官能価のポリメチレンポリフェニルポリイソシアネートを含む混合物である。軟質ポリウレタン発泡体の合成のために好ましいポリイソシアネートは、2,4-トルエンジイソシアネート、2,6-トルエンジイソシアネート、及びこれらの混合物を含むトルエンジイソシアネートであるが、これらには限定されない。
トラメチルプロパンジアミン、メチルトリエチレンジアミン、及びこれらの混合物である。
の材料を噴霧可能な混合物中に存在させることもできる。好ましくは、噴霧可能な組成物はエアロゾルである。好適な噴霧する材料としては、脱臭剤、香水、ヘアスプレー、洗顔剤、及び艶出し剤のような化粧材料、並びに抗ぜんそく薬及び口臭予防薬並びに定量吸入薬(MDI)のような医薬材料が挙げられる(ただし、これらのものに限定されない)。
[0051]発泡剤として、1336mzzm、1233zd(E)、1233zd(E)/1336mzzmの30/70モル%ブレンド、及び1233zd(E)/1336mzzmの70/30モル%ブレンドを用いて発泡体を調製した。ポリオールマスターバッチの組成を表1に示し、一方、対応する量の発泡剤を用いる一般的な噴霧発泡体配合物を表2に示す。3秒間の注入時間及び8秒間の混合時間を用いて発泡体を製造した。原材料の温度は、ポリオールが50°FでMDIが70°Fであった。
[0053]乳化時間、ゲル化時間、及び不粘着時間の間の関係を予測する。これらは製造した全ての発泡体に関して同等である。
[0056]当初は、1336mzzmを用いて製造された発泡体は、高沸点の発泡剤を用いて通常見られる非線形曲線形状を示す。これは、発泡剤の沸点より低い温度において発泡剤が発泡体マトリクス中に濃縮されるためである。1336mzzm/1233zd(E)の30/70モル%ブレンド及び1336mzzm/1233zd(E)の70/30モル%ブレンドは共沸組成物ではないので、同じ曲線形状を示さないことは予期しないことである。更に、これらのブレンドを用いて製造された発泡体の熱伝導率は、1233zd(E)を用いて製造されたものよりも大きく向上する。これらが向上するだけでなく、向上は、発泡剤ブレンドに加える1336mzzmの量に対して非線形の関係である。低い平均温度における向上が大きく、1233zd(E)の濃度には依存しないことは特に興味深い。更に、これらのブレンドから製造される発泡体は、1233zd(E)及び1336mzzm発泡体よりもゆっくりと経時変化することは注目に値する。
