Description
しかし、これは、増加した量の水が熱伝導性を増加させる可能性が高い工業において望ましくない。
本発明の他の目的は、冷却ユニットの製造に有用な硬質ポリウレタンフォームの製造方法を提供することである。
(a)有機イソシアネートを、
(b)平均分子量が少なくとも約149、好ましくは約149〜約1500であり、エポキシド分が、アミン開始剤およびエポキシドの合計重量に基づいて約65〜約98重量%、好ましくは約75〜約98重量%である、アミンに基づくポリエーテルポリオールと、
(c)(1)少なくとも1つの水素含有フルオロカーボン、(2)ある量の水、および(3)追加量の二酸化炭素、からなる発泡剤、
(d)触媒、および
(e)少なくとも1つの界面活性剤、
の存在下に、イソシアネート指数約0.9〜約3.0、好ましくは約1.00〜約1.50で反応させる。生成物フォームは、通常、75°Fにおいて約0.120BTU-in./hr.ft2 °F〜0.160BTU-in./hr.ft2 °Fのkファクターを有する。
下記の実施例に使用した物質は以下のとおりである:
ポリオールA:スクロース、プロピレングリコールおよび水開始剤をアルコキシル化することによって製造され、ヒドロキシル価約450〜490mg KOH/gを有し、Bayer CorporationからMultranol 9196の名称で市販されているポリエーテルポリオール;
ポリオールB:OH価378〜398および官能価4を有し、Bayer CorporationからMultranol 8114の名称で市販されている芳香族アミン開始のポリエーテルポリオール;
ポリオールC:ヒドロキシル価約240mg KOH/gおよび官能価約2.0を有し、Stepan CompanyからStepanpol PS 2502Aの名称で市販されている芳香族ポリエステルポリオールブレンド;
ポリイソシアネートA(NCO A):NCO含量が約30.2%である改質高分子ジフェニルメタンジイソシアネートプレポリマー、CAS #184719-86-6;
触媒A(CAT.A):Air Products and Chemicals, Inc.からPolycat 8の名称で市販されている第三級アミン触媒;
触媒B(CAT.B):RheinChemieからDesmorapid PVの名称で市販されているポリウレタンフォームの製造に有用な触媒;
界面活性剤(Surf.):Air Products and Chemicals, Inc.からDC-5357の名称で市販されているシリコーン界面活性剤;
HFC-245fa:Honeywell International Inc.から市販されている1,1,1,3,3-ペンタフルオロプロパン。
表1に挙げた成分を表示した量で反応させることによってフォームを製造した。ポリオール、触媒、界面活性剤、水および発泡剤を混合してマスターバッチを調製した。次に、マスターバッチを、表1に示した量のポリイソシアネートと混合した。Hennecke MQ 12-2ミックスヘッドを取り付けたHennecke HK-100高圧発泡機を使用して、全てのフォームを製造した。液体アウトプットを一定の60lbs/分に維持し、循環および注入圧力を1500psigに維持した。79インチ(200cm)×8インチ(20cm)×2インチ(5cm)の内容積を有し、120°F(49℃)に温度調節したBosch型に注入したフォームパネルから、最低充填密度を測定した。次に、最低充填密度より高い4つの密度0.15、0.20、0.25および0.30lb/ft3で、パネルを製造した。各パネルの上半分を、10個の4インチ(10cm)切片にカットし、少なくとも16時間にわたり−4°F(−20℃)に暴露した。有意な寸法変化を示さなかった最低密度を有するパネルを、凍結安定性であるとみなした。フォーム特性の検査用のその他のパネルは全て、この「凍結安定密度」で製造した。kファクターは、Lasercomp FOX 200熱流計によって、35°F(2℃)および75°F(24℃)で中心コアにおいて測定した。これらフォームの特性も表1に示す。
