Abstract
Description
しかし、特許文献1~4に記載されている(メタ)アクリル酸アルコシキカルボニルメチルエステル基含有ポリマーからなる防汚塗膜は、塗膜溶解性が著しく低いため長期間に亘って防汚性を発揮することは困難であった。
これらの問題を解決するべく、長期間に渡って塗膜溶解し防汚性能を発揮させる技術が提案されている(特許文献5)。
1.防汚塗料組成物
本発明の防汚塗料組成物は、共重合体Aおよび防汚薬剤を含有し、共重合体B及び他の添加剤を含有してもよい。
共重合体Aは、単量体(a)と、単量体(a)以外のエチレン性不飽和単量体単量体(b)の共重合体であり、単量体(a)及び単量体(b)に由来する単量体単位を含む。単量体(a)と単量体(b)の合計に対する単量体(a)の含有量は、10~90質量%が好ましく、20~70質量%が更に好ましい。具体的には例えば、10、15、20、25、30、35、40、45、50、55、60、65、70、75、80、85、90質量%であり、ここで例示した数値の何れか2つの間の範囲内であってもよい。この場合に、塗膜溶解性が特に良好となる。
単量体(a)は、単量体(a1)と単量体(a2)で構成される。単量体(a)中の単量体(a1)の含有量は、50~80質量%であり、55~75質量%が好ましく、60~70質量%がさらに好ましい。単量体(a1)は、単量体(a2)に比べて、塗膜強度を高め、塗膜溶解性を低下させる性質を有する。このため、単量体(a1)の含有量が少なすぎると、塗膜強度が低くなりすぎて、長期間経過後に塗膜表面状態が悪くなりやすくなる場合がある。一方、単量体(a1)の含有量が多すぎると、塗膜溶解性が低くなりすぎて、防汚性能が低下してしまう場合がある。単量体(a1)の含有量は、例えば、50、55、60、65、70、75、80質量%であり、ここで例示した数値の何れか2つの間の範囲内であってもよい。
単量体(a1)は、一般式(1)で表される。
単量体(a2)は、一般式(2)で表される。
単量体(b)は、単量体(a)以外のエチレン性不飽和単量体である。単量体(b)は、単量体(b1)と単量体(b2)に分類することができ、共重合体Aの重合に用いる単量体(b)には、単量体(b1)と単量体(b2)の一方又は両方が含まれる。
単量体(b2)は、単量体(b)から単量体(b1)を除いたものである。言い換えると、単量体(b2)は、一般式(1)~(3)の何れでも表されない単量体である。単量体(b2)としては、一般式(1)~(3)で表されない(メタ)アクリル酸エステル、ビニル化合物、芳香族化合物、二塩基酸のジアルキルエステル化合物等が挙げられる。なお、本明細書において、(メタ)アクリル酸エステルは、アクリル酸エステル、又はメタアクリル酸エステルを意味する。
共重合体Aの重量平均分子量(Mw)は5000~300000であることが望ましい。分子量が5000未満であれば、防汚塗料の塗膜が脆弱となり、剥離やクラックを起こし易く、また、300000を超えると、重合体溶液の粘度が上昇し、取扱いが困難となるからである。このMwは、具体的には例えば、5000、10000、20000、30000、40000、50000、60000、70000、80000、90000、100000、200000、300000であり、ここで例示した数値の何れか2つの間の範囲内であってもよい。
その中でも、酢酸ブチル、酢酸イソブチル、ブチルアルコール、プロピレングリコールモノメチルエーテル、プロピレングリコール1-モノメチルエーテル2-アセタート、トルエン、キシレンが好ましい。これら溶媒については、単独あるいは2種以上を組み合わせて使用できる。重合反応における反応温度は、重合開始剤の種類等に応じて適宜設定すればよく、通常50~160℃であり、好ましくは60~150℃である。
共重合体Bは、単量体(b1)と単量体(b2)の共重合体であり、単量体(b1)と単量体(b2)に由来する単量体単位を含む。単量体(b1)と単量体(b2)の合計に対する単量体(b1)の含有量は、10~90質量%が好ましく、20~70質量%が更に好ましい。具体的には例えば、10、15、20、25、30、35、40、45、50、55、60、65、70、75、80、85、90質量%であり、ここで例示した数値の何れか2つの間の範囲内であってもよい。この場合に、塗膜溶解性が特に良好となる。
本発明の組成物中における共重合体Bの含有量は特に制限されないが、共重合体Aとの含有割合が、固形分換算で、質量比(共重合体B/共重合体A)は、通常0.1~0.9であり、好ましくは0.3~0.7である。この質量比は、例えば、0.1、0.2、0.3、0.4、0.5、0.6、0.7、0.8、0.9であり、ここで例示した数値の何れか2つの間の範囲内であってもよい。

これらの防汚薬剤は1種又は2種以上併用して使用できる。
さらに本発明の防汚塗料用樹脂には、必要に応じて、共重合体A及びB以外の樹脂成分、溶出調整剤、可塑剤、顔料、染料、消泡剤、脱水剤、揺変剤、有機溶剤等を添加して防汚塗料とすることができる。
重合体Pは、前記単量体(b2)を重合することにより得られる重合体である。
本発明においては、単量体(b2)を単独又は二種以上で用いることができ、特に、共重合体Aとの相溶性の観点から、(メタ)アクリル酸メチル、(メタ)アクリル酸エチル、(メタ)アクリル酸ブチル、(メタ)アクリル酸イソブチル、(メタ)アクリル酸t-ブチル、(メタ)アクリル酸2-エチルヘキシル、(メタ)アクリル酸2-メトキシエチル、(メタ)アクリル酸2-エトキシエチル、(メタ)アクリル酸フルフリル、(メタ)アクリル酸テトラヒドロフルフリル、(メタ)アクリル酸ベンジル等が好ましい。

本発明の組成物中における重合体Pの含有量は特に制限されないが、共重合体Aとの含有割合が、固形分換算で、質量比(重合体P/共重合体A)は、通常0.1~0.5であり、好ましくは0.1~0.3である。この質量比は、例えば、0.1、0.2、0.3、0.4、0.5であり、ここで例示した数値の何れか2つの間の範囲内であってもよい。
前記ロジン誘導体としては、水添ロジン、不均化ロジン、マレイン化ロジン、ホルミル化ロジン、重合ロジン等を例示できる。

この中でもロジン、ロジン誘導体、ナフテン酸、バーサチック酸、トリメチルイソブテニルシクロヘキセンカルボン酸、又はこれらの金属塩が好ましい。
本発明の防汚塗料組成物は、例えば、共重合体及び防汚薬剤、他の添加剤等を含有する混合液を、分散機を用いて混合分散することにより製造できる。
前記混合液としては、共重合体及び防汚薬剤等の各種材料を溶媒に溶解または分散させたものであることが好ましい。
前記分散機としては、例えば、微粉砕機として使用できるものを好適に用いることができる。例えば、市販のホモミキサー、サンドミル、ビーズミル、ディスパー等を使用することができる。また、撹拌機を備えた容器に混合分散用のガラスビーズ等を加えたものを用い、前記混合液を混合分散してもよい。
