Abstract
본 발명은 난연성 스티로폼의 난연성 첨가물에 관한 것으로서, 현재 단열, 보냉 등 건축자재로서 사용하고 있는 스티로폼이 화재 발생시 인화성이 강하여 인화시에 유독가스를 발생 시키는 문제점등을 개선 하고자 본 발명의 유기 및 무기 복합 난연성 분말을 5-20％ 첨가하여 화재시에 열에 의하여 피막형성, 수분의 발생, 불활성기체를 발생시켜 산소를 차단하여 스티로폼이 불이 붙지 않고, 유독가스의 발생도 되지 않는 것을 특징으로 하는 난연성 스티로폼의 난연성 첨가물에 관한 것이다.The present invention relates to a flame retardant additive of flame retardant styrofoam, and to improve the problems such as styrofoam, which is currently used as a building material such as heat insulation and cold insulation, to generate toxic gas at the time of fire due to the high flammability in case of fire. Flame-retardant styrofoam characterized by adding 5-20% of flame retardant powder to prevent film formation, generation of moisture and inert gas by heat in case of fire to block oxygen, so that styrofoam does not catch fire and does not generate toxic gas. Relates to flame retardant additives.
