Description
本出願は、本明細書に完全に述べられているのと同様に引用により援用される2015年10月30日に出願された米国特許仮出願第62/248,543号の非仮出願であり、それに対する優先権の主張を行うものである。
本発明は、コールドボックスまたは非焼成プロセスにおいて用いるためのポリウレタンベースの結合剤系に関する。この系においては、芳香族溶剤を少なくとも部分的に置き換えるためにアルコールが用いられる。特に、選択されるアルコールは2から5の炭素原子を有するアルキルアルコールである。最も具体的には、選択されるアルコールはエタノールである。加えてより具体的には、2成分ポリウレタンベース結合剤系のポリオール含有成分においてアルコールが用いられる。
組成物Aと呼ばれる第1の調合物は、次のパートI成分を有した。
組成物Bと呼ばれる第2の調合物は、次のパートI成分を有した。
組成物Cと呼ばれる第3の調合物は、次のパートI成分を有した。
各場合に1.2重量%の結合剤レベルを有するウェドロン(Wedron)410,51GFNケイ砂に対して、引張り強度テストを行った。
揮発性有機炭素(「VOC」)は、いくつかの異なるテストによって測定され得る。これらのテストの第1のものは、EPAメソッド(Method)24である。そのテストにおいては、重量0.3~0.5gのサンプルを3mlのアセトンに溶解して、110℃のオーブンに1時間入れる。VOCのパーセンテージは失った重量に基づく。組成物C、AおよびB、すなわちフェノールウレタン非焼成結合剤ベースラインと、2つのエタノール含有系とのパートI成分に対して、このテストを行った。それぞれの%VOCは53.9%、51.8%、および49.8%であった。これらの結果は本質的に等しく、区別できるものではない。パートII成分は実際にEPAメソッド24に従ってテストされなかったが、組成物AおよびBについては、高いイソシアネートおよびAROMATIC 100構成要素の不在のために5%VOC未満であると考えられる。従来のパートII成分は、20%から40%の範囲のEPAメソッド24に従うVOC含有量を有するため、エタノール含有系は系全体に対するVOC含有量を低減させることが予期されるだろう。
