- a glass container prepared using BASF Japan's Rubiscol K90.
- Test Example 5 Evaluation of adsorption action on cysteamine (evaluation method) 1.8 mL of water was added to a centrifuge tube containing 0.1 mL of each of the slurries produced in Production Examples 1 to 17, and the mixture was shaken well at room temperature to form a uniform dispersion, and then the concentration was 5.86 wt%. Further, 0.1 mL of cysteamine aqueous solution was added, and the mixture was shaken well for 30 seconds, and then the centrifugation treatment was performed for 90 seconds.
- the supernatant was taken out from the centrifuge tube, the absorbance at 235 nm was measured, and the cysteamine concentration of the supernatant was obtained from the concentration of the cysteamine aqueous solution and the calibration curve of the absorbance, and ((0.293 wt% -cysteamine concentration of the supernatant) / 0. From the formula of .293 wt%) ⁇ 100, the adsorption rate (%) for each cysteamine of the slurry produced in Production Examples 1 to 17 was calculated.
- the absorbance was measured using a Corona Absorption Grating Microplate Reader SH-1000 manufactured by Corona Electric Co., Ltd.
- Reference Example 2 Zeta potential of the slurry produced in Production Examples 1 to 17
- the zeta potential, particle size, and molecular weight measurement system (ELSZ-2000ZS) of Otsuka Electronics Co., Ltd. was used for measurement.
- the results are shown in Table 3.
- the larger the absolute value of the zeta potential the larger the electrostatic repulsive force and the higher the dispersion stability.
- the slurry produced in Production Example 15 is a slurry in which mesoporous silica doped with copper and aluminum is uniformly dispersed, but the absolute value of its zeta potential is 30 mV or more.
- a slurry in which mesoporous silica doped with copper and aluminum is uniformly dispersed can be added to an aqueous solution of a cationic polymer such as polyquaternium-10, polyquaternium-11, or amodimethicone or an aqueous dispersion.
- a cationic polymer such as polyquaternium-10, polyquaternium-11, or amodimethicone or an aqueous dispersion.
- the negatively charged mesoporous silica doped with copper and aluminum and the cationic polymer cause charge cancellation, and as a result, they are cross-linked by adsorption, etc., and aggregate and collect.
- the agglomeration causes precipitation.
- the absolute value of any zeta potential is smaller than the absolute value of the zeta potential of the slurry produced in Production Example 15, and the electrostatic repulsive force is small. Nevertheless, it is considered that the high dispersion stability in the slurry is due to the repulsive force due to the high steric hindrance of the polymer containing the vinylpyrrolidone unit present on the surface of the mesoporous silica doped with copper and aluminum.
- the dispersion stability can be maintained. It is considered to be contributing.
- the reason why the slurry produced in Production Examples 16 and 17 cannot maintain the dispersion stability after being blended in an aqueous solution of a cationic polymer or an aqueous dispersion is that the surface modifier used contains a vinylpyrrolidone unit. It is considered that this is because it has a chemical structure that does not bring about a repulsive force due to high steric hindrance like a polymer.

また、請求項6記載の金属がドープされた多孔質シリカは、請求項1記載の金属がドープされた多孔質シリカにおいて、ビニルピロリドンユニットを含有する重合体が、ポリビニルピロリドンである。
また、本発明のビニルピロリドンユニットを含有する重合体で表面修飾されてなる、金属がドープされた多孔質シリカの製造方法は、請求項7記載の通り、金属がドープされた多孔質シリカを分散媒に懸濁させてなるスラリーを、ビニルピロリドンユニットを含有する重合体およびボールミルに用いるボール(メディア)とともに処理容器に収容し(さらに分散媒を収容してもよい)、これらを収容した処理容器をボールミル架台に載せて回転させることにより、金属がドープされた多孔質シリカを表面処理する工程を含む。
また、本発明のスラリーは、請求項8記載の通り、ビニルピロリドンユニットを含有する重合体で表面修飾されてなる、金属がドープされた多孔質シリカを、分散媒に懸濁させてなる。
また、本発明は、請求項9記載の通り、請求項1記載のビニルピロリドンユニットを含有する重合体で表面修飾されてなる、金属がドープされた多孔質シリカの、ポリクオタニウム-10、ポリクオタニウム-11、アモジメチコン、ポリビニルピロリドンからなる群から選択される少なくとも一種を含む物品に配合することによる、物品に対する消臭のための使用である。
まず、界面活性剤と、金属をメソポーラスシリカにドープするための原料を、溶媒に溶解し、例えば30~200℃で0.5~10時間攪拌することで、界面活性剤にミセルを形成させる。
次に、工程1において得た、界面活性剤がミセルを形成する溶液に、シリカ原料を例えば室温で溶解し、均一になるまで攪拌して、界面活性剤のミセルの表面にシリカ原料を集積させる。シリカ原料の溶液への溶解量は、例えば0.2~1.8mol/Lである。或いは、溶媒として水や水と水溶性有機溶媒の混合溶媒を用いる場合、水1molに対し、例えば0.001~0.05molである。
次に、界面活性剤のミセルの表面に集積させたシリカ原料を脱水縮合させて、メソポーラスシリカを構成するシロキサン結合からなる無機ネットワークを形成させるとともに、無機ネットワーク中に金属を化学結合させて組み込ませる。シリカ原料の脱水縮合は、例えば、系内に塩基性水溶液を添加してpHを上げた後、室温で1時間以上攪拌することで行わせることができる。塩基性水溶液は、pHが添加直後に8~14となるように添加することが好ましく、9~11となるように添加することがより好ましい。塩基性水溶液の具体例としては、水酸化ナトリウム水溶液、炭酸ナトリウム水溶液、アンモニア水が挙げられるが、好ましくは水酸化ナトリウム水溶液である。塩基性水溶液は、単独で用いてもよく、2種以上を組み合わせて用いてもよい。なお、シリカ原料の脱水縮合は、系内に塩酸水溶液などの酸性水溶液を添加してpHを下げた後、攪拌することで行わせることもできる。
最後に、工程3において得た、メソポーラスシリカを構成するシロキサン結合からなり、金属が化学結合して組み込まれた無機ネットワークを表面に形成させた界面活性剤のミセルを、沈殿物として濾過して回収し、例えば、30~70℃で10~48時間乾燥した後、400~600℃で1~10時間焼成することで、目的とする金属がドープされたメソポーラスシリカを得る。こうして得た金属がドープされたメソポーラスシリカは、必要に応じてミキサーやミルで粉砕し、所望する粒径(例えばメディアン径を0.01~100μmとすることがパーマ処理剤中に安定に分散維持させることが容易である点において好ましい)を有するようにしてもよい。
界面活性剤としてのヘキサデシルトリメチルアンモニウムクロライド、銅をメソポーラスシリカにドープするための原料としての塩化銅、アルミニウムをメソポーラスシリカにドープするための原料としての塩化アルミニウムを、溶媒としての水に溶解し、100℃で1時間攪拌した後、室温まで冷却してから、シリカ原料としてのテトラエトキシシランをさらに溶解して均一になるまで攪拌した。次いで、反応液に、塩基性水溶液としての水酸化ナトリウム水溶液を、添加直後のpHが9となるように添加し、室温で20時間攪拌した。生成した沈殿物を濾過して回収し、50℃で24時間乾燥した後、570℃で5時間焼成することで、目的とする銅とアルミニウムがドープされたメソポーラスシリカをごくわずかに青みがかった白色粉末として得た。
ヘキサデシルトリメチルアンモニウムクロライド:0.225mol
塩化銅:0.0204mol
塩化アルミニウム:0.0482mol
水:125mol
また、塩基性水溶液としての水酸化ナトリウム水溶液を調製するために、水酸化ナトリウムを、シリカ原料としてのテトラエトキシシラン1molに対し、0.195mol用いた。

(評価方法)
製造例1~17で製造したスラリーのそれぞれ0.1mLを入れた遠沈管チューブに、水1.8mLを加え、室温で、よく振って均一な分散液とした後、濃度が5.86wt%のシステアミン水溶液0.1mLをさらに加え、30秒間よく振ってから、遠心分離処理を90秒間行った。その後、遠沈管チューブから上澄みを取り出してその235nmにおける吸光度を測定し、システアミン水溶液の濃度と吸光度の検量線から、上澄みのシステアミン濃度を求め、((0.293wt%-上澄みのシステアミン濃度)/0.293wt%)×100の計算式から、製造例1~17で製造したスラリーのそれぞれのシステアミンに対する吸着率(%)を算出した。なお、吸光度の測定は、コロナ電気社のコロナ吸光グレーティングマイクロプレートリーダSH-1000を用いて行った。
結果を表3に示す。表3から明らかなように、製造例1~17で製造したスラリーのいずれもが、システアミンに対する高い吸着率を有しており、銅とアルミニウムがドープされたメソポーラスシリカを、表面修飾剤で表面修飾したことによるシステアミンに対する吸着率の低下は認められなかった。
大塚電子社のゼータ電位・粒径・分子量測定システム(ELSZ-2000ZS)で測定した。結果を表3に示す。一般に、ゼータ電位の絶対値が大きいほど静電反発力が大きく分散安定性が高い。事実、製造例15で製造したスラリーは、銅とアルミニウムがドープされたメソポーラスシリカが均一に分散したスラリーであるが、そのゼータ電位の絶対値は30mV以上である。しかしながら、こうして銅とアルミニウムがドープされたメソポーラスシリカが均一に分散したスラリーであっても、ポリクオタニウム-10、ポリクオタニウム-11、アモジメチコンといったカチオン性高分子の水溶液や水分散液に配合されると、負の電荷を帯びている銅とアルミニウムがドープされたメソポーラスシリカと、カチオン性高分子の間で、電荷の打ち消し合いが起こり、その結果、両者が吸着することなどによって架橋され、凝集して集塊化することで沈殿が生じる。これに対し、製造例1~14で製造したスラリーは、いずれのゼータ電位の絶対値も、製造例15で製造したスラリーのゼータ電位の絶対値に比較して小さく、静電反発力が小さいにもかかわらず、スラリー中で分散安定性が高いのは、銅とアルミニウムがドープされたメソポーラスシリカの表面に存在するビニルピロリドンユニットを含有する重合体が有する高い立体障害性による反発力に起因すると考えられ、この反発力が、カチオン性高分子の水溶液や水分散液に配合された後においても、カチオン性高分子と凝集して集塊化することを阻害することで、分散安定性の維持に寄与していると考えられる。製造例16,17で製造したスラリーが、カチオン性高分子の水溶液や水分散液に配合された後に分散安定性を維持することができないのは、用いた表面修飾剤が、ビニルピロリドンユニットを含有する重合体のように高い立体障害性による反発力をもたらさない化学構造であるからと考えられる。製造例15で製造したスラリーを、ノニオン系高分子であるポリビニルピロリドンの水溶液に配合すると、沈殿が生じる理由は、上記のような電荷の打ち消し合いによるのではないと考えられ、必ずしも明確ではない。しかしながら、製造例2で製造したスラリーを配合すると沈殿が生じないのは、やはり、銅とアルミニウムがドープされたメソポーラスシリカの表面に存在するポリビニルピロリドンが有する高い立体障害性による反発力に起因すると考えられる。
