    Abstract: A manufacturing method of a fire retardant polystyrene foam board is provided to improve fire retardant of board because fusing degree of polystyrene foam beads is controlled by melting-reducing agent in manufacturing. A manufacturing method of a fire retardant polystyrene foam board comprises the steps of: a step(A) which manufactures polystyrene bead; a step (B) which coats melting-reducing agent on the surface of the manufactured polystyrene bead; a step(C) which manufactures foaming bead by foaming the polystyrene bead in which the melting-reducing agent is coated; a step(D) which molds the foaming board by using the foaming bead; a step(E) which injects flame retardant agent into the foaming board; and a step(F) which dries the foaming board in which the flame retardant agent is injected. In the step of molding the foaming board, fusing degree of the foaming bead is degraded by the melting-reducing agent.

    Abstract translation: 提供阻燃聚苯乙烯泡沫板的制造方法以改善板的阻燃性,因为聚苯乙烯泡沫珠的熔融度由制造中的熔融还原剂控制。 阻燃聚苯乙烯泡沫板的制造方法包括以下步骤:制造聚苯乙烯珠的步骤(A); 在制造的聚苯乙烯珠粒的表面上涂覆减少还原剂的步骤(B); 步骤(C),其通过使其中涂覆有所述降解剂的聚苯乙烯珠发泡而制造发泡珠粒; 通过使用发泡珠模制发泡基板的工序(D) 将阻燃剂注入发泡基板的工序(E) 以及干燥喷射阻燃剂的发泡基板的工序(F)。 在发泡板的成型工序中,发泡珠的熔融度被熔融还原剂降解。
