Abstract

In this study, we synthesized and identified microcapsule containing isocyanate, and investigated the mechanical and adhesion properties of polyurethane resin by adding microcapsule. We found out that the core material of microcapsule and the component weight fraction of microcapsule from the FT-IR and TGA analysis. From the results of adhesion and mechanical property tests, we confirmed that in case of using microcapsule for adhesive resin composition, adhesion strength, tensile strength and abrasion were improved by cross-linking reaction between urethane and IPDI in microcapsule.

본 연구에서는 내부에 이소시아네이트를 포함하는 microcapsule을 합성하였으며, 제조된 microcapsule에 대한 분석 및 폴리우레탄 수지와 병용했을 때의 기계적 물성과 접착특성에 대해서 고찰하였다. 전자현미경을 사용해서 합성된 microcapsule이 구형의 외관을 갖는 것을 확인하였으며, FT-IR과 TGA 분석을 통해서 microcapsule의 core 물질이 IPDI인 것과 각 구성요소들의 성분비를 확인하였다. 폴리우레탄 수지 자체 및 microcapsule을 포함한 경우의 접착력 및 물성을 평가한 결과 접착수지 내에 포함된 microcapsule 내 IPDI의 가교반응에 의해서 폴리우레탄 수지 자체에 비해 접착력, 인장강도, 내마모 특성이 크게 향상되는 것을 확인하였다.
