Abstract
Description
粉末状またはスラッジ状の市販の二酸化チタンを溶媒に溶解して、懸濁液を調製するために使用し、少量の二硫化炭素化合物をこの懸濁液に添加して混合し、溶媒を除去した後、残渣を乾燥温度で乾燥し、それから、カ焼温度でカ焼する。例えば、水を溶媒として使用
することができる。
らに、別の色の変化が起こるまで行われることが好都合である。
《実施形態1−インテリア用途のためのシリコーン樹脂塗料》
[実施例]
《比較例》
実施例2において、約10m2/gのBET表面積の二酸化チタン顔料(アナタース形、市販品、Kronos 1000)が12重量%のペンタイリスライトとともに混合されて、熱処理された。
《測定法》
a)光学値の測定(PLV試験)
vlP−TiO2の明るさL*、着色a*および着色b*に対する光学値を決定するために、以下の方法が役立つ。フランクフルトのMATRA社の小さい油圧プレスを使用して特定条件下で試験するために、vlP−TiO2から圧縮粉末が調製された。それから、圧縮粉末の許容値(remission value)がHUNTERLAB三刺激比色計を使用して決定された。
b)光活性の測定(汚染物の分解)
人工可視光線:
15mgのvlP−TiO2が、4−クロロフェノールの2.5×10-4モル溶液の15ミリリットルの超音波浴内で10分間分散され、それから水冷された丸いキュベット内の光学台上において光に晒された。光活性を測定するための光に対する露出は、焦点集中ランプケース(AMKO Mod. A1020, 焦点長さ:30cm)内に設置されたOsram XBO 150 W キセノン短アークランプを使用して実行された。このランプのスペクトルは図10に示されている。反応は、15ミリリットルの容量で、内径が30mmで、厚みが20mmの水冷された丸いキュベット内で実行された。懸濁は、キュベット容器の側面に付着された撹拌モータおよび撹拌磁石を使用して実行された。丸いキュベット容器は図11に示されている。キュベット容器はランプの焦点に保持された。光はキュベット容器の反応空間が露出するように焦点が合わされた。すべての部品は光学台上にしっかりと固定された。紫外線を排除するために、λが455以上である透過率のカントフィルター(Fa. Schott)が光線の経路に導入された。光に晒されることによって反応空間が加熱されることをできる限り防ぐために、IRフィルターが光線の経路に付加的に設置された。このフィルターは水が満たされたシリンダー(直径が6cmで、長さが10cmのもの)である。
インテリア空間の分散光:
50mgのvlP−TiO2が、4−クロロフェノールの2.5×10-4モル溶液の50ミリリットルの超音波浴内で10分間分散され、それからエリアンメイヤー(Erienmeyer)フラスコ(100ミリリットル)内の内部空間の自然光に撹拌しつつ晒された。
空気で飽和されたアセトアルデヒドガス(2容積%)またはベンゼン蒸気(5容積%)または一酸化炭素で満たされた丸いフラスコ(1リットル)内に、vlP−TiO2が両側に被覆された2つの丸いフィルター(紙製で、直径dが15cmで、1枚のフィルター当たり2mgの触媒)が導入された。それからそのフラスコは自然光に晒され、汚染物の減少と一酸化炭素の形成がIR分光器を使用して測定された。
c)炭素含有量の測定
その測定は、LECO C-200炭素検出器を使用して全有機炭素量(TOC)を測定するという条件で実行された。その測定は、酸素ガスによって誘導炉内のvlP−TiO2に含まれる有機物質の燃焼量と、IR検出器を使用して形成された二酸化炭素の生成量を測定するものである。重量で表示すると、約0.4gであった。
d)BET(Brunauer-Emmett-Teller)による比表面積の測定
BET表面積が、静的容量法に基づくマイクトロメリティクス社(Mictromeritics)のトリスター(Tristar)3000を使用して測定された。
e)XPSの測定
Phi 5600 ESCA 分光器(23.5eVの通過エネルギー;アルミニウムの標準;300.0W;45.0℃)が結合エネルギーを測定するために使用された。
f)ESRの測定
電子スピン共鳴スペクトルを測定するために、Bruker Elexys 580 分光器のX−バンド(9.5GHz)が使用された。試料は、10-5トールまで減圧された後、10-2トールまでヘリウムが充填され、それから溶解された。測定は以下の条件で行われた。
g)乱反射スペクトルの測定(クベルカ−ムンク関数)
粉体の乱反射スペクトルが、Shimadzu UV 2401PC UV/Vis 分光器を使用して測定された。その分光器には、ウルブリヒト球体が備えられていた。硫酸バリウムが白色の標準として使用され、測定の前に乳鉢内で粉末を得るために粉砕された。クベルカームンク関数は吸光度に比例している。
h)超親水性
水とvlP−TiO2または非変性TiO2の接触角を測定するために、それぞれ蒸留水中において懸濁され、浸漬被覆法を使用して5cm×5cmのアルミニウム板に付着され、400℃で1時間焼成された。引きつづいて、自然光の中で保管した後、非変性TiO2の接触角を測定すると21゜であり、vlP−TiO2の接触角を測定すると8゜であった。被覆されていないアルミニウム板の接触角は91゜であった。
