The present invention relates to a foamed soundproof and fire-retardant insulation material, and more specifically, to a foamed soundproof and fire-retardant insulation material which settles the issues of conventional insulation materials. The conventional insulation materials are not sufficiently fire retardant. Those products with fire-retardant effects are not burned by fire easily, but they have no function to prevent flames or heat from being transferred to the inside. Thus, ignition occurs inside and makes the fire greater. The present invention settles negative issues of conventional insulation materials by combining foamed nonflammable sponge made from environmentally friendly non-toxic materials and oxy-pad materials, which are thin but serve as insulation materials, or Styrofoam panels with two iron plates. The present invention manufactures the environmentally friendly fire-retardant EVA panel with a fire-retardant composition which comprises: 50-60 wt% of EVA; 5-10 wt% of phosphorus-based ...
