The Study on Properties of CTBN Modified Epoxy Resin

박재홍, 신영조

초록

DGEBA type 에폭시 수지는 화학적인 구조 특성으로 인하여 근본적으로 충격성, 신장성등에 한계점이 있다. 이점을 보완하기 인해서 CTBN을 비롯하여 PTBN, ETBN, HTBN 등으로 변성시켜서 사용하는 경우가 있는데 본 연구에서는 toughening효과가 가장 좋은 CTBN을 이용하여 에폭시 수지와 공중합시켰을 때의 변성된 에폭시 수지의 특성과 경화된 도막의 에폭시의 물성을 고찰하였다.

Unmodified DGEBA type epoxy resin has substantially limited mechanical properties such as impact strength and elongation due to rigid chemical structure. Reactive liquid rubber, CTBN is introduced In DGEBA epoxy resin to improve mechanical properties. Typical properties of CTBN modified epoxy resin and film properties of CTBN modified epoxy film were investigated.
