초록

광경화성 수지인 아크릴레이트의 경화 특성과 메카니즘에 대하여 Photo-DSC와 FTIR, Raman spectrometer를 이용하여 조사하였다. 아크릴레이트 종류, 관능기 수, 광 세기 등에 따른 경화 속도에 관한 정보는 시간에 따른 Photo-DSC curve에서 계산하였고, FTIR과 Raman을 이용하여 경화 반응의 전환율과 반응 메카니즘을 조사하였다. 광경화 반응에서 산소의 영향을 알아보기 위하여 아크릴레이트 수지와 thiol-ene 수지의 경화과정을 비교하였는데, 공기 중 산소가 아크릴레이트의 라디칼 반응에서 금지제로 작용하여 아크릴레이트 수지는 80% 이하의 전환율을 보인 반면 thiol-ene 수지는 산소가 반응에 영향을 미치지 않는 것을 알 수 있었다.

The curing mechanism and characteristics of UV curable acrylate resins were studied using Photo-DSC, FTIR, and Raman spectroscopy. Effects of chemical structures of acrylate, numbers of functional group, and UV intensity on curing kinetics were investigated with Photo-DSC. FTIR and Raman spectroscopy has been used to understand curing mechanisms and reaction conversion. In order to investigate the effect of oxygen on the photo-curing reaction, the curing process was compared between the acrylate and thiol-ene resins. The reaction conversion was found to be less than 80% for acrylate resins. The photo-curing reaction of the acrylate resin could not proceed to the end because of oxygen which acts as a reaction inhibitor while the thiol-ene resin was hardly affected from oxygen during the curing process.
