에폭시 수지의 물성 향상을 위한 최근 동향
Recent Trend for Performance Improvement of Epoxy Resin
초록
대표적인 열가소성 수지인 에폭시 수지는 그 용도 및 응용분야가 광범위하지만, 경화 후 수지의 brittleness 와 고온 및 습윤하에서 물성이 좋지 않아 시용에 제한을 받고 있다. 본고에서는 수지의 최대결점인 brittleness 개선과 고온 습윤 특성의 향상 방법에 대해 고찰하였다. Brittleness 개선 방법으로는 rubber 및 열가소성 수지를 에폭시 수지에 도입하여, 이에 따른 toughness 향상 정도를 중점적으로 다루었으며, 고온 습윤 특성을 향상시키기 위해 에폭시 수지의 molecular design 및 열가소성 수지의 응용방법에 대해 기술하였다.
Epoxy resins have been widely used for many applications along with good processibility. However, epoxy resin systems have poor hot/wet performance properties and brittleness after resin curing and have limited to apply for environmental resistant materials. In order to improve the toughness of epoxy resin, this review article deals with incorporation method of rubber and high performance thermoplastics into the matrix resin. In addition, molecular design of epoxy resin and modification of thermoplastic have been introduced for improving hot/wet properties of epoxy resin.
