Abstract

Using a mechano-fusion process, this study investigated the synergistic effect between two flame retardant particles by producing core-shell structured composite particles. The polyurethane adhesive containing the composite particles showed significantly improved adhesion (up to 150%) and peak heat rebrase rate (PHRR) decreased by 30% compared to those containing only single particles. In particular, adding composite particles showed better properties than using individual particles, and the adhesive strength increased linearly with increasing additive amount. The flame retardant used in this study is a biobased material that is eco-friendly and made from recycled materials, contributing to resource circularity. The research findings reported here are expected to contribute to the development of new environmentally friendly flame retardant materials based on bioresources in the future.


본 연구는 건식 입자 코팅 방법을 사용하여 코어-쉘 구조 복합입자를 제조하여 두 난연제 입자 간의 시너지 효과를 조사하였다. 합성된 난연제의 첨가 전후에 따라서 폴리우레탄 접착제의 접착력은 최대 150% 증가하였고, 최대열방출율(PHRR, 난연성)은 30% 감소하였다. 특히 단일 입자를 사용한 시료보다 복합입자를 첨가한 경우가 보다 우수한 난연성을 나타냈으며, 첨가량이 증가할수록 접착력의 경우 선형적 증가를 확인할 수 있었다. 본 연구에서 사용된 난연제는 바이오 소재로 친환경적이고 폐자원으로부터 재활용된 소재를 함께 사용함으로써 자원 선순환 구조에 기여할 것으로 예상된다. 앞으로 본 연구에서 보고한 연구결과는 향후 바이오기반의 새로운 친환경 난연제 및 난연소재 개발에 기여할 수 있을 것으로 사료된다.
