Abstract

Among many types of flame retardants, the most available halogen-containing flame retardants were put under environmental restrictions in their use, so non-halogen type phosphorus-based flame retardants have come into the spotlight. When added to resins, flame retardants commonly bring about thermal degradation and decrease in mechanical properties of resins. Studies of new flame retardants were carried out in an attempt to minimize degradation of physical properties and require enough flame retardancy. In this study, three types of non-halogen phosphorus-based flame retardants were synthesized with diaryl alkyl phosphate esters, aromatic phosphate esters and phosphonium nitron flame retardants, which were then identified for the synthesis and thermal properties by gas chromatography (GC), IR and thermal gravimetric analysis (TGA).

난연제 가운데 가장 많이 사용되는 할로겐 함유 난연제는 사용상 환경적인 제한을 받고 있어서 비할로겐타입인 인계에 기초한 난연제가 각광을 받고 있다. 난연제는 수지에 가해지는 경우에 흔히 열분해와 기계적 특성저하를 일으킨다. 물성의 열화를 최소화하고 충분한 난연성을 얻기 위한 시도로 새로운 난연제에 대한 연구를 수행하였다. 본 연구에 있어서는 diaryl alkyl phosphate esters, aromatic phosphate esters 및 phosphonium nitron 난연제 등 세가지 형태의 비할로겐 인계에 기초한 난연제를 합성하여 GC, IR 및 TGA 등으로 합성 및 열적 특성을 확인하였다.
