Description
水相に、モノマーとしてスチレン(Styrene)、安定化剤として4‐ビニルベンゼンスルホン酸ナトリウム(Sodium 4‐vinylbenzenesulfonate)、開始剤としてアゾビスイソブチロニトリル(Azobisisobutyronitrile,AIBN)を混合して、75℃で8時間反応させた。反応は、円筒形反応器で撹拌し、円筒形反応器は、直径11cm、高さ17cm、ガラス材質であり、200rpmの速度で回転させた。
前記得られたポリスチレン(Polystyrene,PS)第1ポリマー球状粒子に、モノマーとしてスチレン(Styrene)、TMSPA(3‐(trimethoxysilyl)propylacrylate)、開始剤としてアゾビスイソブチロニトリル(Azobisisobutyronitrile,AIBN)を混合して反応させた。反応は、円筒形反応器で撹拌した。
前記反応の結果、得られたポリスチレン‐コアシェル(PS‐CS)水分散溶液に、モノマーとしてスチレン(Styrene)、安定化剤として4‐ビニルベンゼンスルホン酸ナトリウム(Sodium 4‐vinylbenzenesulfonate)、開始剤としてアゾビスイソブチロニトリル(Azobisisobutyronitrile,AIBN)を混合し、75℃に加熱して反応を進めた。反応は、円筒形反応器で撹拌して、両親媒性異方性粉体を得た。
前記得られた異方性粉体の水分散溶液600gに、シランカップリング剤としてN‐[3‐(トリメトキシシリル)プロピル]エチレンジアミン(N‐[3‐(Trimethoxysilyl)propyl]ethylenediamine)30gと、反応調節剤としてアンモニウムヒドロキシド(Ammmonium hydroxide)60gを混合して、25℃で24時間反応させて親水性官能基を導入した。反応は、円筒形回転反応器で攪拌して、親水化された両親媒性異方性粉体を製造した。
前記準備例3において製造された異方性粉体を利用して、下記表1の油中水型乳化組成物を製造した。
異方性粉体を含有する乳化組成物の安定性を確認するために、前記実施例1の乳化組成物と比較例1の従来の乳化組成物を、黒い四角形のプラスチック板に約1.5gずつ取り出し、床から45度に立てた状態で15分間保持して粘度を比較した。結果を図1の写真に示した。
前記実施例1の組成物を、それぞれ−15℃〜−25℃の冷凍状態で2ヶ月保管して、および−20℃以下での冷凍を1週間以上保持した後に解凍を4回繰り返しながら2ヶ月間保管して、温度による乳化粒子の安定性を観察し、観察された光学顕微鏡写真を図2に示した。
前記実施例1の組成物を30℃で12週間保持しながら、組成物の粘度変化をViscometer(LVDV‐II+PRO,BROOKFIELD,USA)を使用して測定し、結果を図3に示した。
