Description
本実施形態における油分吸着材は、無機粒子がコアを構成し、ポリマーがコアを被覆して凝集したものである。本発明は、油分吸着材に対し、この無機粒子の割合が体積換算で50〜97%、好ましくは70〜90%であり、かつ油分吸着材の断面に存在する無機粒子の面積が全体の30〜60%であることを特徴とする。
次に、上述した本実施形態の油分吸着材の製造方法について説明する。
なお、本実施形態で、“親水性”とは、水と自由に混和するものと定義し、具体的には1気圧において温度20℃で同容量の純水と緩やかにかき混ぜた場合に、流動がおさまった後も当該混合液が均一な外観を維持するものである。
次に、上述の油分吸着材を用いた油分回収方法について説明する。油分回収は、油分を含む水から、油分を分離するものである。ここで“油分”とは、水中に混和/分散している有機物のうち、一般に常温において液体であり、水に難溶性であり、粘性が比較的高く、水よりも比重が低いものをいう。より具体的には、動植物性油脂、炭化水素、芳香油などである。これらは、脂肪酸グリセリド、石油、高級アルコールなどに代表される。これらの油類はそれぞれ有する官能基などに特徴があるので、それに応じて上記油分吸着材を構成するポリマーや官能基を選択することができる。
ポリスチレン(G590;日本ポリスチレン株式会社製,密度1.05 g/cm3)6重量部を、300mlのテトラヒドロフラン中に溶解させて溶液とし、その溶液中に平均粒子径1000nmの八面体マグネタイト粒子40重量部(密度5.0g/cm3,比表面積3.0m2/g)を分散させて組成物を得た。
実施例1とは樹脂の量(無機粒子の含有率)を変えたこと以外は同様にサンプルを作製した。結果を表1に示す。樹脂の量が少なくなる(無機粒子の含有量が多くなる)と断面の向き粒子が少なくなり、空孔ができる傾向にあった。油分吸着率は樹脂の量が少なくなるほど良かった。
実施例1とは樹脂の量を0.1gに変えたこと以外は同様にサンプルを作製した。結果を表1に示す。この組成物はスプレードライ直後は凝集体の形を成していたが、水中で攪拌すると崩壊し、ほとんど一次粒子になってしまった。油分吸着量は測定することができなかった。
実施例1とは樹脂の量を10gに変えたこと以外は同様にサンプルを作製した。結果を表1に示す。この組成物の断面は内部と外部で無機粒子の存在密度に差があるものの、組成物の表面の無機粒子間の隙間が一部埋まっていた。油分吸着率を測定したところ96.9%であった。
実施例1とは噴霧温度を変えたこと以外は同様にサンプルを作製した。結果を表1に示す。温度を上げていくと組成物の断面の無機粒子の存在密度に傾斜がでてきて、噴霧温度120℃以上(沸点+63.5℃)では半数ほどが中空粒子に、140℃では7割程度が中空粒子となっていた。油分吸着率は低い温度で作製したものよりも高かった。
実施例1とは噴霧温度を55℃(沸点−1.5℃)に変えたこと以外は同様にサンプルを作製した。結果を表1に示す。温度を下げると組成物の断面の無機粒子の存在密度に傾斜ができなくなり、中まで詰まった組成物となった。油分吸着率は75℃で作製したものよりも低かった。
