Abstract

Thermal curing behaviors of acrylate mixtures, which consist of photo-curable monomers and cross-linkable diacrylate oligomers, were studied under various curing conditions. The curing kinetics and curing degree of the mixtures were investigated using time-resolved FTIR spectroscopy by monitoring IR characteristic peaks of urethane thermal and acrylate photo-curing reactions. The thermal curing process of the mixture was compared with the dual curing process that is composed of urethane thermal-curing after acrylate photo-curing process. The effects of molecular weight of the diacrylate oligomer and of the acrylate monomer structures on the thermal curing kinetics were investigated.


열경화 반응을 할 수 있는 아크릴레이트 단량체들과 가교반응을 할 수 있는 diacrylate 올리고머의 혼합물에 대한 경화조건 변화에 따른 열경화 거동을 조사하였다. 열경화에 의한 우레탄 반응과 아크릴레이트의 광경화 반응을 time-resolved FTIR 실험으로 각 반응의 특성 IR 피크를 관찰하여 혼합물의 경화 속도와 경화율 변화를 측정하였다. 혼합물에 대하여 우레탄 열경화만 진행한 거동을 아크릴레이트 광경화 후 우레탄 열경화를 진행한 복합경화 경우와 비교하였다. Diacrylate 올리고머의 분자량과 아크릴레이트 단량체의 구조에 따른 우레탄 열경화 속도 변화를 조사하였다.
