Abstract

The purpose of this study is to develop an organic-inorganic hybrid insulation materials which has an economic feasibility of organic level and excellent adiabatic performance and fire stability by impregnating organic materials with inorganic binder solutions. The organic base was commercial polyurethane sponge, and the inorganic binder slurry was prepared by mixing water and additives into recycled gypsum byproducts. As a result of evaluation of the developed materials, it was confirmed that it not only has excellent insulation performance of a thermal conductivity of 0.051 W/mK or less but also it is a semi-non-combustible materials specified in the Ministry of Land, Infrastructure and Transport Notice No. 2015-744. The developed materials can also be controlled for thermal conductivity and flame retardance according to density control during manufacturing process, and thus it can be applied to various insulation materials.

본 연구는 유기계 기재에 무기계 바인더 소재를 함침시킴으로써 유기계 수준의 경제성을 가지며 우수한 단열성능 및 화재 안전성을 보유한 유무기 융합형 단열재 개발을 목적으로 한다. 유기계 기재는 폴리우레탄 소재의 상용 스펀지를 사용하였고, 함침용 무기 바인더 용액은 재활용 석고 부산물에 물과 첨가제를 혼합하여 제조하였다. 개발 소재의 성능평가 결과 열전도율 0.051W/mK 이하의 우수한 단열성능 뿐만 아니라 국토교통부 고시 제 2015-744호 기준에 명시된 준불연 재료임을 확인할 수 있었다. 또한 본 개발 소재는 제조 공정 과정에서 밀도 제어에 따른 열전도율 및 난연성 조절이 가능하여 다양한 용도의 단열재에 적용 가능할 것으로 판단된다.
