초록

비닐 에스테르 수지(vinyl ester resin, VER)는 우수한 기계적, 화학적, 열적 특성 및 빠른 경화 특성을 가지고 있어 다양한 산업 분야에 사용되고 있다. VER은 일반적으로 상온에서 촉매를 이용한 경화 방법이 주로 이용되고 있으나 물성 향상을 위하여 반드시 후경화가 필요하다. 본 연구에서는 전자빔 조사에 의하여 후경화된 VER 상온경화물의 기계적 물성을 분석하였다. 분석 결과, 전자빔 조사에 의하여 VER 상온 경화물의 후경화가 진행되며, 전자빔 흡수선량이 증가함에 따라 기계적 물성이 향상되었음을 확인하였다. 또한 전자빔 조사에 의하여 후경화된 VER 상온 경화물의 기계적 물성은 열에 의하여 후경화된 샘플과 거의 동등함을 확인하였다.

Vinyl ester resins (VERs) are used in various industrial fields due to their chemical, mechanical and thermal properties as well as rapid curing characteristics. Although VERs are generally cured at room temperature using a catalyst, the post-curing process is necessary to improve the physical properties of VERs. In this study, the room temperature-cured VER was irradiated with electron beams of 1.0 MeV at various absorbed doses, and the mechanical properties of electron beam-irradiated VER were investigated. The results revealed that VER was successfully post-cured by electron beam irradiation, and the mechanical properties increased with an increasing absorbed dose. The mechanical properties of the VER post-cured by electron beam irradiation were comparable to those of the thermally post-cured VER.
