초록
충전제의 종류 및 분산 시간에 따른 박막의 특성 평가를 실시하였으며, 그 결과 투과도 측면에서 유리한 중공 실리카를 선택하여 충전제의 함량별 그리고 코팅 두께별 haze, 투과도, 그리고 광택도에 대한 실험을 각각 실시하였다 그 결과, 충전제의 함량이 증가할수록 haze값은 증가하고 광택도 값은 이와는 반대로 감소하였다. 또한, 필름 표면에의 코팅 두께가 증가할수록 충전제의 함량변화 때와는 정 반대로 haze값은 감소하고 광택도는 증가하였다. 그리고 투과도의 경우에는 두 가지 경우 모두 거의 일정한 수준으로 변화를 보이지 않았다. 결론적으로 충전제로서 중공 실리카를 사용할 경우 함량 증가와 투과도면에서 매우 유리함을 알 수 있었다.
The effect of filler type and dispersion time on thin film characterization is studied. Hollow silica powders which have the advantage of transmittance are selected. In this paper, the characterization of haze, transmittance, and gloss are analyzed in terms of filler concentration and coating thickness, respectively. As a result, the value of haze and gloss increased with increasing of filler concentration and coating thickness, respectively. In addition, the variation of transmittance by filler concentration and coating thickness is not occurred. In conclusion, it is assumed that hollow silica powders as a filler have an advantage of concentration increment and transmittance.
