초록

자동차의 유리를 폴리카보네이트로 대체하기 위하여 폴리카보네이트 판 위에 하드 코팅을 시도하였다. 본 연구에서는 [3-(methacryloyloxy)propyl]trimethoxysilane으로부터 졸-겔 과정을 이용하여 코팅을 실시하였다. Butanol을 용매로 사용하였고, 촉매로는 HCI을 이용하였으며, 개시제로는 AIBN을 이용하였다. 폴리카보네이트 판은 PMMA를 이용하여 전처리를 하였으며, 코팅의 열처리는 $130^{\circ}C$에서 6 h 동안 하였다. 형성된 코팅의 연필 경도는 2 H이었고, 내마모성과 접착력이 매우 우수한 코팅이 형성되었다.

The hard coatings on the polycarbonate plate were performed with the object of substitution the glass in the car to the polycarbonate plate. In this research, [3-(methacryloyloxy)propyl]trimethoxysilane were used to prepare the coatings by sol-gel process. Butanol was used as a solvent, HCl was used as a catalyst, and AIBN was used as an initiator. Polycarbonate plate was pretreated with PMMA, and final heating of the coating was done at $130^{\circ}C$ for 6 h. Pencil hardness of the coating was 2 H, abrasion resistance and adhesion of the coating were excellent.
