Abstract

Electron beam (EB) and ultraviolet (UV) curable monomers (AF-1 with mono functionality and AF-2 with tetra functionality) containing hydroxy and acrylate group for anti-fogging coating were synthesized and applied to EB and UV-curable coating systems. The synthesized reactive AF-1 and AF-2 monomers were first formulated into UV-curable system and the optimization of film properties for anti-fogging coating was investigated. The 5:17.5 ratio for AF-1 and AF-2 was found to be the best optimized formulation for anti-fogging coating without destroying the other essential properties such as hardness, solvent resistance, and adhesion. The optimized formulation was applied to the EB-curable system, and EB and UV-curable systems were compared. The results demonstrated that both EB and UV-cured films coated on PC sheet showed excellent anti-fogging properties; however, the EB-cured film exhibited better hardness, adhesion, and water repellent properties than the UV-cured film.

분자 내에 방무기능을 부여하기 위한 수산기와 전자선(EB) 및 자외선(UV) 경화가 가능한 아크릴레이트 관능기를 갖는 1관능성 및 4관능성 방무제 AF-1과 AF-2를 합성하여 EB 및 UV 경화시스템에 적용하였다. 합성된 AF-1과 AF-2를 UV 경화시스템에 적용하여 도막의 방무특성 및 경화물성을 측정한 결과, AF-1과 AF-2 함량을 5:17.5의 비로 함유한 배합이 표면과 내부경도, 내화학성 및 접착력이 저하되지 않으면서 김서림 방지 특성이 우수한 최적배합임을 알 수 있었다. 이 최적배합을 EB 경화시스템에 적용하였고, EB 및 UV 두 시스템에 의해 이루어진 코팅배합물을 PC sheet에 코팅하여 도막의 방무특성 및 경화물성을 비교 연구하였다. 그 결과 EB 및 UV에 의해 경화된 두 시스템 모두 우수한 방무특성을 나타냈으나 EB 시스템이 UV 시스템보다 더우수한 내부경도, 접착력 및 젖음성을 나타냄을 확인하였다.
