dc.description.abstractThiol/epoxy/acrylate를 기반으로 한 듀얼 경화 접착제는 두 가지 경화 메커니즘을 통한 경화 반응을 수반하도록 설계하였다. 접착제에 안정화제를 투입함으로써 조기 중합을 억제하여 저장안정성이 개선된 듀얼 경화 접착제를 제조할 수 있었다. 설계된 듀얼 경화 반응은 UV/열의 공정을 수반하며 광경화는 365 nm에서 3분간 광조사를 통해 진행하고 순차적으로 열경화는 90 ℃에서 30분간 진행하였다. 안정화제 효과를 연구하기 위해 단일 종 또는 두 가지의 안정화제를 혼합하여 투입하였다. 안정화제 종류 및 함량별 접착제 점도 특성 변화를 3일간 면밀히 관찰하였다. 듀얼 경화 접착제의 전단 접착 강도는 universal testing machine를 사용하여 측정하였다. 저장안정성과 전단접착강도를 고려할 때 안정화제로 pyrogallol 0.3 wt% 및 lauryl gallate 0.1 wt%를 혼성 첨가하였을 때 물성이 가장 우수하였다.-
dc.description.abstractA thiol/epoxy/acrylate-based dual-cure adhesive is designed to accompany a curing reaction via two curing mechanisms. The addition of a stabilizer to the adhesive is shown to provide a dual-cure adhesive with improved storage stability by suppressing premature polymerization. The dual-curing reaction entails a UV/heating process, wherein the photo-curing is performed via light irradiation at 365 nm for 3 min, followed by thermal-curing at 90 celcius for 30 min. In addition, the effect of the stabilizer is studied by the addition of either a single species or a mixture of two stabilizers, and the changes in the viscosity of the adhesive according to stabilizer type and content are closely monitored for 3 days. The adhesive strength of the dual-curing adhesive is measured using a universal testing machine. The optimum storage sta-bility and adhesive strength are obtained when 0.3 wt% pyrogallol and 0.1 wt% lauryl gallate are used as a mixed stabilizer.-
