초록

실리콘 아크릴레이트를 함유하고 있는 폴리카보네이트용 자외선 경화형 하드코팅 필름의 표면경도 및 광택도에 미치는 주인자 세 가지(올리고머종류, 삼관능 아크릴레이트 모노머 종류 및 실리콘 아크릴레이트 화합물의 농도)를 선정하여 full factorial design을 시행하였다. 그 결과 표면경도에 가장 큰 영향을 주는 인자는 올리고머 종류이며 특히 우레탄 아크릴레이트 올리고머를 사용하는 것보다 폴리에스테르 아크릴레이트 올리고머를 사용할 경우 경도가 높음을 알 수 있었다. 또한, 광택도에 미치는 주인자는 실리콘 아크릴레이트 화합물의 농도임을 알 수 있었다. 통계적 분석 결과에서는 올리고머는 폴리에스테르 아크릴레이트, 삼관능 아크릴레이트는 TMPTA, 실리콘 아크릴레이트는 1 wt% 정도를 사용할 경우, 경도 및 광택도가 우수한 코팅필름을 얻을 수 있었다.

The effects of three variables: oligomer type, triacrylate type and the concentration of silicone acrylate on the surface hardness and gloss of UV curable coating containing silicone acrylate for polycarbonate have been investigated using a full factorial experimental design. The results show that the oligomer type and the concentration of silicone acrylate are the most affective factors affecting surface hardness and gloss of UV cured films, respectively. Specially, when the polyester oligomer was introduced into the coating formulation, the surface hardness of UV cured film was improved as compared with urethane acrylate oligomer. As a result of statistical analysis, the UV cured film from the formulation of polyester acrylate oligomer, trimethyolpropane triactylate (TMPTA) and 1 wt% of silicone acrylate showed the best surface hardness and gloss.

Keywords:experimental design;UV curable;silicone acrylate;hardness;gloss
