The present invention relates to a flame retardant composition for coating styrofoam, styrofoam coated with the composition, and a manufacturing method thereof and, more specifically, relates to a flame retardant composition which is provided to be coated on the surface of expanded polystyrene particle foam comprising silica, alumina-silica, pumice, modified silicate and methyl cellulose, to styrofoam coated with the composition, and to a manufacturing method thereof. The flame retardant composition of the present invention has an effect of blocking heat of the expanded polystyrene particle foam coated therewith by flame retardant properties of each component and shows an effect of blocking an oxygen source by coating the expanded polystyrene foam particle. In addition, the flame retardant composition of the present invention exhibits a hardening effect by using both alumina-silica and modified silicate and is capable of preventing the separation and elimination of materials by increasing binding power (adhesive power) and preventing the release of toxic gases caused by the adsorption of toxic gases while maintaining thermal resistance even in the event of high-temperature fire. 본 발명은 스티로폼 코팅용 난연재 조성물 및 이러한 조성물로 코팅된 스티로폼 및 이의 제조방법에 관한 것으로서, 규석, 알루미나-실리카, 부석, 변성 실리케이트, 및 메틸 셀룰로오즈를 포함하는 발포 폴리스티렌 입자 폼의 표면에 코팅처리하기 위한 난연재 조성물, 및 이러한 조성물로 코팅된 스티로폼 및 이의 제조방법에 관한 것이다. 본 발명의 난연재 조성물은 각 성분들의 난연 성질에 의해 이로 코팅된 발포 폴리스티렌 폼 입자와의 열을 차단하는 효과를 가지고, 발포 폴리스티렌 폼 입자를 코팅함으로써 이와 산소원을 차단하는 효과를 나타낸다. 또한, 본 발명의 난연재 조성물은 알루미나-실리카와 변성 실리케이트를 함께 사용함으로써 경화시키는 효과를 나타냄과 동시에 발포 스티렌 입자의 결합력(부착력)을 증대시켜, 재료의 분리 및 탈락 등을 방지할 수 있으며, 고온의 화재시에도 열적 저항성을 유지하며 유독가스의 흡착에 의한 유독가스 방출을 방지할 수 있다.
