Description
本出願は、2018年3月28日付の韓国特許出願第10-2018-0035997号および2019年3月11日付の韓国特許出願第10-2019-0027740号に基づく優先権の利益を主張し、当該韓国特許出願の文献に開示されたすべての内容は本明細書の一部として含まれる。
前記無機微細粒子と前記炭素数1~10のアルキレングリコール繰り返し単位を含む(メタ)アクリレート化合物とを有機溶媒に分散した状態で、超音波、高剪断ミキサ(High-Shear Mixer)またはビーズミル(Bead mill)などを用いて強いエネルギーを伝達することによって、前記炭素数1~10のアルキレングリコール繰り返し単位を含む(メタ)アクリレート化合物が無機微細粒子の凝集体の表面または内部に結合できる。このように製造された光触媒複合体は、前記バインダー樹脂に非常に均一に分散し、これにより、光触媒の分解効率が顕著に増加できる。
実施例1~4

下記表1のアルキレングリコール繰り返し単位を含む(メタ)アクリレート化合物0.43gをテトラクロロエチレンに溶解させた後、下記表1に記載された量のTiO2(一次粒子の平均粒径:21nm)を混合し、剪断速度(shear rate)20,000s-1を適用して20分間高速撹拌した。
前記製造された光触媒複合体の分散液、ポリエチレン[LDPE、MI(溶融指数、190℃、2.16kg荷重、ASTM D1238):約8g/10min、D(密度):0.925g/cm3]、エチレンビニルアセテート共重合体[MI(溶融指数、190℃、2.16kg荷重、ASTM D1238):約1.8g/10min、D(密度):0.94g/cm3、ビニルアセテート含有量約20重量%、融点85℃]、およびタルクを下記表1による含有量で用いて、組成の混合比でテトラクロロエチレンと90℃で均一に撹拌混合し、固形分濃度が5重量%となるようにコーティング液を製造した。
比較例1
ポリエチレン[LDPE、MI(溶融指数、190℃、2.16kg荷重、ASTM D1238):約8g/10min、D(密度):0.925g/cm3]、エチレンビニルアセテート共重合体[MI(溶融指数、190℃、2.16kg荷重、ASTM D1238):約1.8g/10min、D(密度):0.94g/cm3、ビニルアセテート含有量約20重量%、融点85℃]、およびタルクを下記表1による含有量で用いて、組成の混合比でテトラクロロエチレンと100℃で均一に撹拌混合し、固形分濃度が5重量%となるようにコーティング液を製造した。
実験例1:光分解特性の比較試験
前記実施例の溶出制御型肥料および比較例の被覆肥料それぞれ5gずつ取って、1粒ずつ針でピンホールを入れてから、内部の肥料を完全に溶出した後、残りの被覆膜で分解評価を進行させた。
実施例3の光触媒複合体の分散液と比較例2のTiO2が含まれている分散液のTiO2のz-平均分散粒度を動的光散乱法(Dynamic Light Scattering、Marvern Zetasizer Nano ZS90)を用いて測定した。その結果を下記表3に示した。
