초록
불소계 아크릴레이트 2,2,2-trifluoroethylmethacrylate을 사용한 자외선 경화형 유-무기 하이브리드 코팅 막에 있어서 무기물 및 사용되는 유기 단량체의 종류 및 조성이 내 오존성 및 표면 특성에 미치는 영향에 대해 연구하였다. 코팅액은 금속 알콕사이드인 tetraethoxysilane(TEOS)와 실란 커플링제인 methacryloyloxypropyltrimethoxysilane(MPTMS)로 구성된 유-무기 혼성 용액에 2,2,2-trifluoroethylmethacrylate와 자외선 경화를 위한 유기물을 첨가하여 제조되었다. 코팅막은 코팅액을 기재위에 바 코팅 한 후 자외선 경화를 통해 제조되었다. 제조된 코팅 막의 내 오존성은 TEOS의 함량이 증가할수록 내 오존성과 표면경도는 향상되었다. 또한, 불소 함량이 증가할수록 내 오존성은 향상되었지만 표면 경도는 다소 떨어졌다. 우레탄 아크릴레이트를 첨가한 코팅 막은 높은 연필경도를 나타내었다. 코팅 막의 투과도는 TEOS와 2,2,2-trifluoroethylmethacrylate의 함량에 큰 영향을 받지 않았다. 더욱이, 코팅 막은 90% 이상의 높은 투과도를 나타내었다.
The effect of synthesis conditions such as various organic material and composition of organic-inorganic material in ozone resistance and surface characteristic of ultraviolet cured organic-inorganic hybrid coating film has been investigated. Organic-inorganic hybrid coating solution was prepared using tetraethoxysilane (TEOS), silane coupling agent methacryloyloxypropyltrimethoxysilane (MPTMS), 2,2,2-trifluoroethylmethacrylate, and various organic materials with acrylate group, bar-coated on substrates using applicator and densified by UV-curing. It was found that ozone resistance and surface hardness of the coating film was increased with contents of TEOS. It was also found that ozone resistance of coating film was increased with contents of 2,2,2-trifluoroethylmethacrylate. On the other hand, surface hardness was decreased with increase of 2,2,2-trifluoroethylmethacrylate. In addition, Surface hardness of coating film was increased with the addition of aliphatic urethane acrylate. It was also found that the transmittance of coating films was not influenced by content of TEOS and 2,2,2-trifluoroethylmethacrylate. In addition, the coating film exhibited high transmittance of above 90%.
