Description
1.(メタ)アクリル酸アルキルエステル、及びカルボキシル基含有モノマーを含むモノマー群の重合体を樹脂成分とし、該モノマー群におけるカルボキシル基含有モノマーの比率が0.2〜20重量%であり、ガラス転移温度が0〜80℃である水分散性樹脂(A)、
1分子中に2以上のエポキシ基を有するエポキシ基含有化合物(B)、
塩基性化合物(C)、及び
アミノ基含有アルコキシシラン化合物(D)を含み、
各成分の混合比率が、前記水分散性樹脂(A)の固形分100重量部に対し、前記エポキシ基含有化合物(B)0.1〜50重量部、前記塩基性化合物(C)0.01〜10重量部、前記アミノ基含有アルコキシシラン化合物(D)0.1〜50重量部であることを特徴とする水性被覆材。
2.前記水分散性樹脂(A)、前記エポキシ基含有化合物(B)、及び前記塩基性化合物(C)を含む主剤、並びに前記アミノ基含有アルコキシシラン化合物(D)を含む硬化剤からなる1.記載の水性被覆材。
モノマー群全体に占める(メタ)アクリル酸エステルの比率は、通常60〜99.8重量%、好ましくは70〜99.5重量%程度である。
このように(メタ)アクリル酸エステルを選択して使用することにより、硬化性、硬度、耐摩耗性、耐久性等において有利な効果を得ることができる。
アルカリ金属シリコネートは、R1aSi(OR2)b(OM)cで表される化合物である。[式中、aは0以上の整数(好ましくは1)、bは0以上の整数(好ましくは2)、cは1以上の整数(好ましくは1)であり、a+b+c=4を満たす。R1は同一または異なるものであってよく、炭化水素基を表す。R2は同一または異なるものであってよく、水素原子または炭化水素基を表す。Mは同一または異なるものであってよく、アルカリ金属を表す。]
R2としては、水素原子の他、R1と同様の基が挙げられる。このうち、水素原子、メチル基、エチル基が好ましく、特に水素原子が好ましい。
Mとしては、Li、Na、K等が挙げられ、特にNaが好ましい。
(F)成分としては、例えば、ジエチレングリコールモノ2−エチルヘキシルエーテル、ジエチレングリコールジブチルエーテル、2,2,4−トリメチル−1,3−ペンタンジオールモノイソブチレート、2,2,4−トリメチル−1,3−ペンタンジオールジイソブチレート等が挙げられる。
塗装の対象となる基材としては、特に限定されず、例えばコンクリート、モルタル、アスファルト、金属、磁器タイル、サイディングボード、押出成形板、プラスチック等の各種基材が挙げられる。このような基材は、既存塗膜等を有するものであってもよい。具体的に既存塗膜としては、例えば、アクリル樹脂系塗膜、アクリルシリコン樹脂系塗膜、ウレタン樹脂系塗膜、エポキシ樹脂系塗膜等が挙げられる。
塗装及びその後の乾燥は、通常、常温(0〜40℃)で行えばよい。本発明の水性被覆材は、比較的温度が低い状態(0〜20℃)においても有利な効果を発揮することができる。
下塗材としては、アクリル樹脂、ウレタン樹脂、エポキシ樹脂、塩化ビニル樹脂等の各種樹脂を結合材として含むものが使用できる。このうち、アクリル樹脂を含む下塗材においては、Tgが10℃以上(好ましくは30℃以上、より好ましくは40℃以上80℃以下)のアクリル樹脂を用いることが望ましい。
(1)アミノ基、アンモニウム基、ホスホニウム基等のカチオン性官能基を有するカチオン性モノマーを、その他の重合性モノマーと共に、乳化重合等の方法によって水性媒体中で重合したもの;
(2)アミノ基、アンモニウム基、ホスホニウム基等のカチオン性官能基を有するカチオン性水溶性樹脂の存在下で、重合性モノマーを乳化重合等の方法によって水性媒体中で重合したもの;
(3)アミノ基、アンモニウム基、ホスホニウム基等のカチオン性官能基を有するカチオン性界面活性剤の存在下で、重合性モノマーを乳化重合等の方法によって水性媒体中で重合したもの;
(4)アミノ基、アンモニウム基、ホスホニウム基等のカチオン性官能基を有するカチオン性有機溶剤系樹脂を、有機酸、無機酸等で中和し水を加えて水性媒体中に分散させたもの;
(5)アミノ基、アンモニウム基、ホスホニウム基等のカチオン性官能基を有するカチオン性界面活性剤を用いて、有機溶剤系樹脂を水性媒体中に分散させたもの;
等が挙げられる。
本発明水性被覆材を既存塗膜に直接塗装する場合は、塗装前に研磨処理等による目荒しを行うことが望ましい。このような目荒しにより、既存塗膜に付着した汚染物質等を除去することができ、さらに、既存塗膜表面に微細な凹凸が形成されることで、密着性をいっそう高めることができる。目荒しは、公知の研磨具、研削具等を用いて行えばよい。
