前記イソシアネート系成分及び/又はポリオール系成分の給送中に、トリエチレンジアミン、N,N−ジメチルシクロヘキシルアミン(DMCHA)、N,N’,N’’−トリス(ジメチルアミノプロピル)ヘキサヒドロトリアジン、N,N,N’−トリメチルアミノエチルエタノールアミン、N,N,N’,N’,N’’−ペンタメチルジエチレントリアミン(PMDETA)、N,N,N’,N’−テトラメチル−1,6−ヘキサンジアミン(TMHDA)のいずれか1つの強アミン系触媒を含む第3成分液を混合することを特徴とする、ポリウレタンフォーム製造方法を提供する。
イソシアネート:ポリメチレンポリフェニルポリイソシアネート
(2)ポリオール系成分
ポリオールA:ポリエステルポリオール(OHV=250)
ポリオールB:ポリエーテルポリオール(OHV=450)
難燃剤 :トリスクロロプロピルフォスフェート(TCPP)
整泡剤 :シリコーン整泡剤
金属系触媒 :オクチル酸カリウム
金属系触媒 :オクチル酸鉛
発泡剤 :水
(3)アミン系触媒
触媒A(弱アミン系触媒):ジメチルアミノエトキシエタノール
触媒B(強アミン系触媒):トリス(ジメチルアミノプロピル)ヘキサヒドロ−S−トリアジン
触媒C(強アミン系触媒):トリエチレンジアミン33%DPG溶液
ハンド発泡により、ポリオール系成分、イソシアネート系成分の2液を混合攪拌後、発泡立ち上がり開始時間(クリームタイム)と、立ち上がり終了時間(ライズタイム)を計測した。
F1600タイプのスプレー発泡機にて、1層30mmをコンクリート板に吹き付けし、表面状態と横伸びを評価した。表面状態評価は、反応性が速く表面平滑に仕上がる場合は「○」、反応性が遅く表面凹凸に仕上がる場合は「×」、これらの中間を「△」とした。横伸び評価は、横伸びが大きく剥離する程度は「×」、横伸びが有るが許容できるレベルは「△」とした。
