Abstract

Cyclophosphazene derivatives were synthesized in order to use as a non-halogen flame retardant for ABS. Chlorocyclophosphazene was reacted with phenol, catechol, aniline, 1,2-diaminobenzene respectively, and each product was characterized by UL94 and LOI test for ABS resin. The physical properties of the sample containing these flame retardants were also characterized. The derivative synthesized from catechol showed best flame retardancy, and the derivative from phenol exhibited the flame retardancy in which the synergic effect was shown with novolac.

할로겐을 포함하지 않은 난연제를 개발하기 위하여 cyclophosphazene 유도체들을 합성하여 이들을 ABS를 위한 난연제로 사용하여 보았다. Chlorocyclophosphazene에 phenol, catechol, aniline, 1,2-diaminobenzene 등을 반응시켜 각각의 유도체들을 합성하였으며 이들이 ABS에 얼마나 잘 난연성을 나타내는지를 UL94, LOI 등으로 살펴보았다. 이들 난연제를 함유하는 ABS 시료의 물성도 알아보았다. Catechol로부터 합성된 유도체가 가장 우수한 난연 결과를 보여주었으며 phenol로부터 합성된 유도체의 경우에는 novolac과 같은 고분자와 혼합한 다음에 첨가하면, 같은 양의 첨가로 더 우수한 난연성을 보여 주었다.
