Description
NOX汚染物質を除去するための本発明のコーティングの能力、そのセルフクリーニング特性ならびにその耐久性を3種の水性スチレンアクリル塗料を調製することにより調べた。比較試料の「組成物1」および「組成物2」の各々は、10容積%の光触媒二酸化チタンを含んだが、対照試料には光触媒は存在しなかった。組成物1に用いた光触媒二酸化チタンは、Millennium Inorganic ChemicalsからのPCS300であった。PCS300は、約5〜約10nm(ナノメートル)の平均結晶サイズを有する光触媒二酸化チタンパウダーである。組成物2に用いた光触媒二酸化チタンは、Millennium Inorganic ChemicalsからのPC105であり、それは約15〜25nmの平均結晶サイズを有する。PCS300およびPC105の双方は、約100%のアナターゼ含量を有する。完全な塗料製剤を表1に供する。
NOX除去を測定するための完全な方法は米国特許公開第2007/0167551号に記載され、その開示をここに出典明示して本明細書の一部とみなす。略言すると、試料を気密試料室に入れ、密閉した。試料室は、3つのチャンネルガスミキサ(Brooks Instruments, Holland)と連絡し、それを介して、NO(酸化窒素)、NO2(二酸化窒素)および水蒸気を含有する圧縮空気を予め決定されたレベルのその試料室に導入する。試料をUV Lamp Model VL-6LM 365 & 312 ナノメーター波長(BDH)からの300〜400nmの範囲の8W/m2のUV照射で照らす。NOXの初期値および最終値(5分照射後)を試料室に接続したNitrogen Oxides Analyser Model ML9841B (Monitor Europe)によって測定した。NOXの%低下を(ΔNOX/初期NOX)×100として測定した。各試料は予めの活性化なくしておよび予めの活性化を有した場合の調査であった。結果を表2にまとめる。
メチレンブルーに対する光活性を決定するために使用した方法は、米国特許公開第2007/0167551号に記載されたものと同様であり、その開示をここに出典明示して本明細書の一部とみなし、その方法は本明細書に記載のごとく変更されている。各塗料試料のセルフクリーニング特性は、有機色素メチレンブルーを分解させるそれらの能力に基づき調べた。その色素が水、二酸化炭素および窒素含有種に対して分解するので、色の損失が観察される。光活性はL*(明度)の測定によりモニターされる。プロトコールは以下の通りである:
塗料の耐久性を決定するための完全な方法は米国特許公開第2007/0167551号に記載されており、その開示をここに出典明示して本明細書の一部とみなす。その方法は、340nmにて550W/m2のUVを照射する6.5kWキセノン源下、Ci65A Weatherometer (Atlas Electric Devices, Chicago)におけるステンレス鋼基材上の20〜50ミクロンの厚みの塗膜の加速耐候性を含む。試料を約63℃に加熱し、水噴霧を暗サイクルなくして120分毎に18分間適用した。耐久性を曝露後の試料の重量損失の関数として測定する。
この実施例のパートIにおいて前記されたNOX除去の決定のための手順を使用して、異なる光源下でNOXを除去するための塗料試料の組成物1および組成物2のそれぞれの能力を決定した。UVに加えて、低強度の蛍光性の線型照明、日光(ガラスを介してフィルタ処理した)およびOsram白熱光源を使用した。各ケースにおいて塗料を事前の活性化なくして試験した。結果を以下の表(表5)にし、図1に示す。
約5〜約15nmの光触媒結晶サイズを有する塗料は、例えば、約5〜10nmの光触媒TiO2粒子サイズを有する実施例1の組成物1と指定された塗料を含めて本発明の好ましい実施例を表すが、スチレンアクリル結合剤の使用を通じて達成可能な高いPVC(顔料容積濃度)の利点も、好ましさがより低い二酸化チタン結晶サイズ(すなわち、約15〜約50nm)で、より穏やかにではあるが見られた。また、例えば、高レベルのPC105光触媒(約15nm〜約25nmの結晶サイズ)を使用する塗料も、NOXを除去するためのコーティングにおいて有用であろう。
PCS300を商業表示PC500下のMillennium Inorganic Chemicalsから入手できる比較可能な100%アナターゼの光触媒二酸化チタンパウダーと代えた以外は実施例1に記載のごとく、スチレンアクリル塗料を実質的に調製した。PC500は、約5〜約10nmの平均結晶サイズに変換される約300m2/gの表面積を有する。PC500は8容量%のレベルで塗料に含まれ、スチレンアクリル結合剤を約50容量%で含んだ。事前の活性化なくしてNOXを除去するためのこの塗料の能力は、実施例1に前記された手順による0.5W/m2〜8W/m2の強度範囲を横切るUV強度の関数として試験した。その結果を表8に示す。
