FLAME-RETARDANT INSULATING BOARD COMPLEX IN WHICH A URETHANE FOAM LAYER IS FORMED BETWEEN FLAME-RETARDANT EXPANDABLE POLYSTYRENE BOARDS AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A flame-retardant insulating board complex is provided to be formed of a urethane foam layer between flame-retardant expandable polystyrene boards, thereby having enough thermal insulation and flame retardancy.;CONSTITUTION: A manufacturing method of a flame-retardant insulating board complex comprises: a step of forming flame-retardant expandable polystyrene boards(10A,10B) by foam molding expandable polystyrene particles in which a flame retardant coating layer including an inorganic flame retardant on the surface of the particles; a step of spreading reaction liquid for forming urethane foam by a reaction on one surface of the flame-retardant expandable polystyrene boards; a step of arranging other flame-retardant expandable polystyrene board to be separated with the space for foaming of the reaction liquid; and a step of forming a urethane foam layer(20) between the flame-retardant polystyrene boards.;COPYRIGHT KIPO 2012
