関西ペイント株式会社技術研究所著、「やさしい技術解説シリーズ(3)水性塗料の技術動向」、第1版、日本塗料新聞社、1994年4月1日、p.52−56
タイペークCR−50(石原産業社製二酸化チタン)200部、SP−600N(ダイセル社製ヒドロキシセルロース系増粘剤)1部、SNデフォーマ1070(サンノプコ社製消泡剤)1部、ディスパービック−190(ビックケミー社製顔料分散剤)15部およびイオン交換水53部を混合した後、ガラスビーズを用いディスパーにて分散し、顔料分散ペーストを得た。
滴下漏斗、温度計、窒素導入管、還流冷却器および撹拌機を備えたセパラブルフラスコにイオン交換水34.5部、ペレックスSS−H(花王社製アルキルジフェニルエーテルジスルホン酸ナトリウム)0.3部を仕込み、窒素雰囲気のもとで80℃に昇温した。スチレン14部、2−エチルへキシルアクリレート57部、メチルメタクリレート22部、エチレングリコールジメタクリレート4部、ジアセトンアクリルアミド1部およびメタクリル酸2部からなる、Tgが−19℃、酸価が13であるモノマー混合液に、ドデシルメルカプタン0.6部を加えた後、これを、ペレックスSS−H1.2部をイオン交換水50部に溶解させた乳化剤水溶液中に加え、ミキサーを用いて乳化させてプレエマルジョンを調製した。なお、モノマー混合液のTgを計算するにあたって、エチレングリコールジメタクリレートのTgはメチルメタクリレートと同じ温度とした。
さらに造膜助剤としてダワノールDPnB(ダウケミカル社製ジプロピレングリコールn−ブチルエーテル、沸点229℃)をエマルション樹脂固形分に対して3質量%加えたこと以外、実施例1と同様にして、顔料体積濃度17%のエマルション塗料組成物を得た。この塗料に含まれるVOCの含有量を実施例1と同様にして分析した結果、3.0質量%であった。
表1の配合に基づいて、モノマー混合液を得たこと以外、実施例1と同様にして、エマルション樹脂2〜4を得た。いずれも固形分50%であり、体積平均粒子径はそれぞれ、125nm、130nm、128nmおよび130nmであった。
実施例1および5で得られたエマルション塗料組成物に対して、各々カルボジライトV−02(日清紡績社製カルボジイミド基含有化合物水溶液、固形分40%)15.0部を混合した。これらの塗料に含まれるVOCの含有量を実施例1と同様にして分析した。結果を表2に記載した。さらに実施例1と同様にして、タック性評価板、耐候性評価板および低温造膜性評価板を得た。
滴下漏斗、温度計、窒素導入管、還流冷却器および撹拌機を備えたセパラブルフラスコに脱イオン水34.5部、ペレックスSS−H0.3部を仕込み80℃に昇温した。スチレン15部、2−エチルへキシルアクリレート46部、メチルメタクリレート17部、ジアセトンアクリルアミド1部およびメタクリル酸1.6部からなる、Tgが21℃である1段目用モノマー混合液にペレックスSS−H1.2部をイオン交換水50部に溶解させた乳化剤水溶液中に加え、ミキサーを用いて乳化させてプレエマルジョンを調製した。このプレエマルジョンと、過硫酸アンモニウム0.3部をイオン交換水13部に溶解させた開始剤水溶液とを別個の滴下漏斗から同時に滴下して1段目の重合を行った。1段目の滴下が終わった30分後にスチレン3部、2−エチルへキシルアクリレート13部、メチルメタクリレート4部、メタクリル酸0.4部からなる、Tgが−29℃である2段目用モノマー混合液にドデシルメルカプタン1部を混合したものを30分にかけて滴下して2段目の重合を行った。なお、1段目と2段目とを合わせたモノマー混合液の酸価は13であった。2段目の滴下が終わった後、同温度でさらに120分間重合を継続した。冷却後、用いたメタクリル酸に対して10モル%に相当するアンモニア水で中和した。これを200メッシュの金網で濾過し、体積平均粒子径160nm、固形分50%のエマルション樹脂6を得た。
表1の配合に基づいて、モノマー混合液を得たこと以外、実施例1と同様にして、エマルション樹脂8〜10を得た。いずれも固形分50%であり、体積平均粒子径はそれぞれ、120nm、126nmおよび125nmであった。
エマルション樹脂および作成した各評価板を以下の通り試験し、評価した。なお、評価結果は表2に示した。
(1)濾過残渣
エマルション樹脂の製造時に発生した200メッシュの金網上の濾過残渣を150℃で1時間乾燥させて残渣率を計算した。
作成した低温造膜性評価板の塗膜表面状態を目視にて、以下の評価基準に従って評価した。
○ :塗膜の割れがない
× :塗膜の割れが確認できる
作成したタック性評価板上に7cm角のウエスを置き、さらにその上に600gのおもりを載せて40℃で24時間放置した後、おもりを取り外して、ウエスを剥がした。ウエスを剥がす時の引き剥がし感をタック性として、以下の評価基準に従って評価した。さらに同様にして48時間放置、72時間放置についても評価した。
◎ :抵抗を全く感じない
○ :抵抗をほとんど感じない
△ :やや抵抗を感じる
× :抵抗を感じる
作成した耐候性評価板をサンシャインウェザオメーター(スガ試験機社製)にて1000時間促進耐候性試験を行い、試験前後の60度光沢値を光沢度計(スガ試験機社製)にて測定し、光沢保持率を、光沢保持率(%)=試験後光沢値/試験前光沢値×100によって算出した。70%以上を合格とした。
