−230乃至400g/100g、好ましくは250乃至350g/100gのDBP値
を有する沈降シリカの、粉砕システム(粉砕装置)を用いた粉砕と分級により調製可能であり、
上記粉砕システムは特に好ましくはジェットミルを含む粉砕システムであり、これは、粉砕システムのミルがガスおよび/または蒸気好ましくはスチーム、および/またはスチームを含むガスからなる群から選択される媒体を用いた粉砕段階中で動作されることと、粉砕チャンバが加熱段階すなわち媒体を用いた実際の動作の前に加熱され、これにより、粉砕チャンバ内および/またはミルアウトレットにおける温度が蒸気および/または媒体の露点よりも高いことと、粉砕されたシリカが150乃至2000nmのd50値および500乃至7000nmのd90値に分級されることと、を特徴とする。出発材料として適した市販のシリカは、Evonik Degussa GmbH(ドイツ国)製Sipernat(登録商標)160、Sipernat(登録商標)22S、Sipernat(登録商標)22LS、および、DWS(中国)製シリカ(等級YH350)である。
LOD[重量%]=(msp−mLOD)×10/msp。msp=オリジナルのサンプル重量[g]、mLOD=乾燥減量後の残渣の重量[g]。
DIN EN ISO787−11の「従来の」タップ密度の決定でもって、シリカが既にたとえばパッキングの過程で予備的な圧縮が行われているという事実により、結果は妥当なものではない可能性がある。これを排除するため、本発明のシリカについて「修正タップ密度」を求めた。環状フィルタ(たとえば、タイプ598、Schleicher&Schull)に合った陶器の吸込フィルタ(通常サイズ110、直径12cm、高さ5.5cm)にシリカを上端から1cmほどまでに緩く充填し、可塑性フィルム(Parafilm(登録商標))で覆った。可塑性フィルムの形状およびサイズは、陶器吸引フィルタユニットの端部でもってフラッシングがほとんどまたは完全に終わるように選択した。このユニットは吸込びんに取り付けられ、−0.7バールの減圧を5分間かけた。この操作の過程で、シリカは吸い込みの下、フィルムによって均一に圧縮された。その後、再び空気を注意深く入れ、フィルタユニットを強く傾けて陶器皿に得られたシリカプラックを取り出した。
シラノール基密度=シラノール基濃度/BET比表面積
修正シアーズ数(以下ではシアーズ数V2)はフリーなシラノール基の数の測定であり、pH6乃至9の水酸化カリウム溶液でのシリカの滴定によって求めることができる。決定方法は、以下の化学反応に基づいた。ここで、≡SiOHはシリカのシラノール基を示す。
≡SiOH + NaCl −> ≡SiONa + HCl
HCl + KOH −> KCl + H2O
水分レベルが5±1%の、微粉、球状または粒状のシリカ10.00gを、IKA(登録商標) M20汎用ミル(550W、20000rpm)を用いて60秒間均一に粉砕した。適切であれば、出発物質の含水率は乾燥棚における105℃での乾燥または均一な含水処理によって調整する必要があり、粉砕プロセスは繰り返した。得られた処理シリカ2.50gを室温で250ml滴下容器に量り出し、メタノール(分析等級)60.0mlと混合した。試料を完全に濡らした後、脱イオン水40.0mlを加え、Ultra−Turrax T25撹拌機(KV−18G攪拌シャフト、直径18mm)を用いて18000rpmの回転速度で30秒間分散させた。脱イオン水100mlを、容器の端および攪拌機に付着した試料粒子のフラッシングに用いて懸濁させ、混合物の温度はサーモスタット付きの水浴中で25℃に制御した。
市販の沈降シリカSipernat(登録商標)160(Evonik DegussaGmbH製、物理化学的データは表1参照。)について、スチーム作動型の流動層カウンタジェットミルでの、加圧下の超微細粉砕を行った。粉砕システム(ミル)の詳細および用いた粉砕方法の詳細は上記の詳細な説明において示している。
断熱材料1:実施例1の沈降シリカ90重量部を、カーボンブラックF101(Evonil Degussa製)10重量部と混合した。断熱材料1の密度は146.2(kg/m2)である。
