<p>An anti-flammable board and a manufacturing method thereof are disclosed. The method for manufacturing an anti- flammable board comprises forming a coating layer for forming micropores, on a surface of a bead impregnated with a foaming agent and a fire retardant agent, forming a plurality of foam particles by expanding the bead, wherein a predetermined steam pressure is applied to expand the bead, forming a board having the micropores formed between the plurality of foam particles, by welding the plurality of foam particles, injecting a fire retardant solution into the micropores, and drying the board. Here, the beads are coated with a coating layer containing an inorganic fire resistant material and then expanded to form foam particles, and the content of a foaming agent in the foam particle and the pressure of a steam applied to the foam particle are adjusted to ensure pores between the foam particles, so that a fire retardant solution can be sufficiently injected into the pores, thereby improving the fire resistance, insurability and intensity of the anti-flammable board.</p> |
