(1)水性澱粉糊化液の製造
イオン交換水178.0gに澱粉(DS−SyncSTA S100、大象(株)、大韓民国)90.6gを投入して分散させた後、7%HClを使用して、pHを6に調節した。1gの耐熱性α−アミラーゼ(Liquozyme supra、Novozyme、デンマーク)を99gのイオン交換水で希釈して調製した澱粉分解酵素液1.2gを、前記反応物に加えた。得られた反応物を、1L容量の4口フラスコ反応槽に加え、90℃で2時間撹拌した。反応物に次亜塩素酸0.6gを加えて酵素活性を失わせた後、80℃に冷却して水性澱粉糊化液を製造した。
前記(1)で得られた水性澱粉糊化液に、反応性乳化剤(HA−100、韓農化成、大韓民国)6.4g、非イオン性乳化剤(FN−8、韓農化成、大韓民国)1.6g及びイオン交換水147.7gを加え、反応器に窒素を充填した。窒素雰囲気下、9.0gのイオン交換水に過硫酸カリウム0.5g及び重亜硫酸ナトリウム0.03gを溶解させた溶液と、メチルメタクリレート20.0g、メチルメタクリル酸5.0g及びn−ブチルアクリレート20.0gの単量体混合物とを、80℃で30分かけて滴下して共重合反応を行った。前記滴下完了後、80℃で1時間撹拌することによって熟成させ、澱粉−第1単量体共重合物を含むエマルジョンを得た。
前記(2)で得られたエマルジョンに、55.0gのイオン交換水に過硫酸カリウム2.8g及び重亜硫酸ナトリウム0.23gを溶解させた溶液と、メチルメタクリレート97.7g、n−ブチルアクリレート137.2g、スチレン40.0g及びn−ドデシルメルカプタン1.0gの単量体混合物とを、80℃で270分かけて滴下して重合反応を行った。前記滴下完了後、80℃で1時間撹拌することによって熟成させ、コア・シェル構造の共重合体を含むエマルジョンを得た。
前記(3)で得られたエマルジョンを55℃に冷却し、t−ブチルヒドロペルオキシド0.9gを16gのイオン交換水に溶解させた溶液と、亜ジチオン酸ナトリウム0.6gを8.0gのイオン交換水に溶解させた溶液とを30分かけて滴下した。反応物を55℃で30分間熟成させた後、室温に冷却してエマルジョン状の水性塗料用接着素材を製造した。前記製造されたエマルジョンの固形分含量を測定した結果、固形分の含量は、約50重量%であった。
前記実施例1の(2)で、反応性乳化剤として、SR−10(アデカ、日本)6.5gを使用したことを除いては、実施例1と同様に行って、エマルジョン状の水性塗料用接着素材を製造した。
前記実施例1の(3)で、第2単量体として、メチルメタクリレート132.4g、n−ブチルアクリレート102.6g及び2−エチルヘキシルメタクリレート40.0gの単量体混合物を使用したことを除いては、実施例1と同様に行って、エマルジョン状の水性塗料用接着素材を製造した。
実施例1の(2)及び(3)を区分せず、1回の重合による単一構造の共重合体エマルジョンを製造した。すなわち、実施例1の(1)で得られた水性澱粉糊化液に、反応性乳化剤(HA−100、韓農化成、大韓民国)6.4g、非イオン性乳化剤(FN−8、韓農化成、大韓民国)1.6g及びイオン交換水147.7gを加え、反応器に窒素を充填した。窒素雰囲気下、9.0gのイオン交換水に過硫酸カリウム0.5gを溶解させた溶液と、メチルメタクリレート117.7g、n−ブチルアクリレート157.2g及びスチレン40.0gの単量体混合物の単量体混合物とを、80℃で30分かけて滴下して共重合反応を行った。前記滴下完了後、80℃で1時間撹拌することによって熟成させ、澱粉−単量体共重合物を含むエマルジョンを得た。
実施例1及び比較例1で得られたエマルジョンの物性を評価した。物性評価項目である不揮発分、粘度、Tg、塗膜状態、密着性、乾燥時間、耐水性を、KS認証試験方法によって、次のように測定した。結果は、下記表1の通りである。
* 不揮発分(固形分)-KS M 6010: 2009
* 粘度-KS M ISO 2555: 2009 (#3, 60rpm)
* 塗膜状態-KS M 5000: 2009
* 密着性-KS M ISO 2409
* 乾燥時間-KS M 6010: 2009
* 耐水性- KS M 5605
