Abstract

Polymers are widely applied to construction materials due to their lightweight and excellent mechanical properties. However, owing to the combustible properties, polymers are one of the biggest reason of spreading large fires in fire accidents that occur frequently in the construction industry. Therefore, as a solution to this problem, many research has been conducted to impart flame retardancy by incorporating flame retardants to polymer matrix. Among these flame retardants, organic phosphorus-containing flame retardants have been attracting much attention because they have excellent compatibility with polymer matrix and low toxicity compared with halogen or inorganic-containing flame retardants. Accordingly, this study aims to design and synthesize an alkoxyamine-based organic phosphorus flame retardant to improve flame retardancy of polylactide which is an eco-friendly polymer used for construction materials.

고분자는 고유의 경량성 및 강성으로 인해 건축 자재에 두루 적용되는 소재이다. 그러나 건축 산업에서 빈번히 발생하는 화재 사고에서 대형 화재로의 확산을 일으키는 가장 큰 원인 중 하나가 가연 특성을 지니는 고분자라고 할 수 있다. 따라서 이를 해결하기 위한 방안으로 고분자 소재에 난연제를 첨가하여 난연 특성을 부여하는 연구가 활발히 진행되고 있는 추세이다. 이 중에서도 유기 인계 난연제는 고분자와의 혼화성이 우수하며, 독성이 낮은 장점을 가지고 있어 많은 주목을 받고 있다. 이에 따라 본 연구에서는 건축자재용으로 사용되는 친환경 고분자인 폴리락타이드의 난연성능을 확보하기 위하여 알콕시아민 기반의 유기 인계 난연제 구조를 설계 및 합성하여 이의 효과를 확인하는 것을 목적으로 둔다.
