초록

우레탄 열반응이 가능한 아크릴레이트 단량체의 UV 광경화 거동을 in-situ로 시분해 푸리에 변환 적외선 분광법(FTIR) 실험과 광 DSC 실험을 수행하여 조사하였다. 아크릴레이트 단량체 사이의 우레탄 열반응을 먼저 진행한 후 UV를 쪼여 아크릴레이트 광반응을 유도한 열-광 복합경화 공정이 UV 광경화만 진행한 경우보다 아크릴레이트 반응은 더 빠르게 진행되었지만, 아크릴레이트의 최종 경화율은 약간 감소하였다. 이와 같은 아크릴레이트 단량체 시스템에 긴 사슬의 아크릴레이트 올리고머를 첨가한 시스템에서도 복합경화 공정이 UV 광경화만 진행한 경우보다 반응은 더 빠르게 진행되었고, 아크릴레이트 경화 정도는 큰 차이 없이 끝까지 진행되었다.

The photo-curing behaviors of acrylate monomers capable of urethane thermal reaction were investigated using time-resolved Fourier transform infrared spectroscopy and photo-differential scanning calorimetry. Faster photo-reaction and lower conversion of acrylate reactions were observed in the thermal-photo dual curing process compared to the photo-curing only process. In the case of the acrylate system with long chain oligomers, faster photo-reaction was also observed in the dual curing process although no difference was found in the degree of conversion for acrylates between two photo-curing processes.
