Description
さらに、高剪断発泡装置などを必要とせずに塗布場所で容易に調製でき、かつ塗布に際して卓越したイールドをもたらす、低密度、高イールド、ポンプ輸送適性、吹付け適性の防火組成物を調製することが望ましいであろう。
本発明のセメント質スラリーの調製に有用な適切な水硬結合剤には、ポルトランドセメント、アルミナセメント、ポゾランセメント(pozzolanic cement)、グナイト(gunite)、硫酸カルシウム2水和物(セッコウ、非水和および水和両方の焼セッコウ(Plaster of Paris))、およびその混合物が含まれ、セッコウが特に好ましい。ポルトランドセメントは、耐水性が重要な場合、または交通量が多く、より高密度(たとえば240.3〜480.6kg/m 3 (15〜30pcf)、より一般的には352.4〜416.5kg/m 3 (22〜26pcf))の被膜が望ましい地域で選択される結合剤として知られている。セッコウは高密度用途に使用できるが、通常は低密度(たとえば約80.1〜394.4kg/m 3 (5〜19pcf)、好ましくは約160.2〜240.3kg/m 3 (10〜15pcf))組成物に用いられる。好ましくは、結合剤は約10〜約98重量%、より好ましくは約90〜約95重量%の量で用いられる。好ましくは、水硬結合剤を微細に分割した乾燥粉末状で供給する。
すべての場合、表1に挙げた水以外のすべての材料を3分間乾式ブレンドして均一な混合物を得た。次いでこの混合物を標準的な櫂形撹拌機に添加し、水を添加した。この組み合わせを2分間混合した。生成したスラリーをローター/スターター式ポンプ(Putzmeister S−5)のポンプホッパーに注入した。次いでスラリーを他の位置へポンプ輸送し、ここでホース内のスラリーに空気を注入した。この空気注入により、スラリーは9.1m(30フィート)、1.90cm(3/4インチ)の発泡用ホース内でフォームに変化した。
”ショットクリート(shotcrete)”塗布(トンネルや鉱道の壁のシーリング)に用いるのに適した本発明のポンプ輸送および吹付けしたフォームの例においては、表1の配合物6に用いたスタッコおよび遅延剤の代わりに、ポルトランドセメントを追加する。配合物6に用いたセルロースおよびガラス繊維の代わりに、ショットクリート塗布に用いられる一般的な鋼繊維を用い、得られた配合物を前記実施例1〜6と同様に処理し、ただしアルミン酸ナトリウムを凝結促進剤として硫酸アルミニウムの代わりに用いる。
この例は、ポリビニルアルコールの支持体接着凝集増強特性を証明する。ポリビニルアルコールをセッコウベースの市販防火用製品(試料1)に添加した。用いた配合物を次表に示す。
