Abstract
Description
まず、本発明の第1の実施形態に係る防汚塗膜の製造方法について詳細に説明する。図1は、本発明の第1の実施形態に係る防汚塗膜の製造方法を示すフロー図である。図1に示すように、本実施形態の防汚塗膜の製造方法は、下記の工程(1)〜工程(3)を含む。なお、図1中において、例えば「工程(1)」を「S1」と略記する(以下同様。)。
図2は、工程(1)で用いる樹脂からなる表面を有する基材の一例を模式的に示す断面図である。図2に示す基材20は、樹脂成分を含む塗料を用いて形成した塗膜21を鋼板23上に有するものである。また、図3は、工程(1)における微細凹凸層を有する基材を模式的に示す断面図である。なお、上記説明したものと同等のものについては、それらと同一の符号を付して説明を省略する。図3に示すように、基材20の表面上に微細凹凸層11が形成されている。なお、図示しないが、微細凹凸層は、上述したように、シリカ及びポリシラザンを含んでいる。
図4は、工程(2)における微細凹凸層及び改質層を有する基材を模式的に示す断面図である。なお、上記説明したものと同等のものについては、それらと同一の符号を付して説明を省略する。図4に示すように、基材20の表面上に微細凹凸層11及び改質層13が形成されている。なお、図示しないが、微細凹凸層は、上述したように、シリカ及びポリシラザンを含んでいる。また、改質層は、上述したように、ポリシロキサン又はパーフルオロポリエーテルを含んでいる。なお、改質層は、ポリシロキサン及びパーフルオロポリエーテルの双方を含んでいてもよい。
上記工程(3)で用いるシリコーンオイル又はフッ素オイルを含む潤滑油は、シリコーンオイル又はフッ素オイルを含む潤滑油層を形成し得るものであれば、特に限定されるものではない。潤滑油はシリコーンオイル自体やフッ素オイル自体でもよい。例えば含浸されて潤滑油層を形成するという観点からは、潤滑油は、表面エネルギーが低く、不揮発性であるものが好適である。具体的には、ジメチルシリコーンオイルや変性シリコーンオイルなどのシリコーンオイル、フルオロポリエーテルオイルやパーフルオロポリエーテルオイルなどのフッ素オイルを好適例として挙げることができる。なお、改質層がポリシロキサンを含む場合には、シリコーンオイルを適用することが好ましく、改質層がパーフルオロポリエーテルを含む場合には、フッ素オイルを適用することが好ましいが、これに限定されるものではない。また、シリコーンオイル及びフッ素オイルの双方を適宜用いてもよい。
次に、本発明の第2の実施形態に係る防汚塗膜について詳細に説明する。図5は、本発明の第2の実施形態に係る防汚塗膜を有する基材を模式的に示す断面図である。なお、上記説明したものと同等のものについては、それらと同一の符号を付して説明を省略する。
樹脂からなる表面を有する基材の一例である塗装板として、リン酸亜鉛処理したダル鋼板に、カチオン電着塗料を電着塗装し、さらに、カラーベース塗料を塗装し、さらに、クリヤー塗料(ウレタン系樹脂を主成分とする。)を塗装して得られたものを用いた。また、フーリエ変換型赤外分光分析(FT−IR)による評価に用いる試料を作成するため、アルミニウム基板を用意した。
表1に示すように、微細凹凸層形成剤を代えたこと以外は、実施例1と同様の操作を繰り返して、各例の防汚塗膜を得た。
(フーリエ変換型赤外分光分析(FT−IR)による評価)
上記各例のフーリエ変換型赤外分光分析(FT−IR)評価用試料(アルミニウム基板上に形成した微細凹凸層)を用いて、フーリエ変換型赤外分光分析(FT−IR)評価を行った。具体的には、フーリエ変換型赤外分光光度計(日本分光株式会社製、FT/IR−4200typeA)を用い、使用ピークをSiH(2200cm−1)、SiO(1100cm−1)として、微細凹凸層形成剤塗布直後と3日経過後におけるSiO/SiHについて、バックグラウンドを除去したピーク高さの比を求めた。得られた結果を表1に併記する。
上記各例の防汚塗膜を用いて、転落角測定を行った。具体的には、DSA100(Kruss社製)を用い、純水20μLにおける初期転落角及び耐熱後転落角を測定した。得られた結果を表1に併記する。なお、初期転落角とは、防汚塗膜形成直後における転落角である。また、耐熱後転落角とは、防汚塗膜形成後、90℃で4時間耐久させた後における転落角である。
