<p>PURPOSE: A method for manufacturing flame retardant and insulation interior and exterior construction panels using waste styrofoam is provided to guarantee high insulation and noncombustible effects by forming phosphate composite with cement, charcoal, or waste plastic powder. CONSTITUTION: A method for manufacturing flame retardant and insulation interior and exterior construction panels using waste styrofoam comprises the following steps. Waste styrofoam lump is roughly crushed and pulverized by a geared motor-type grinder in three stages to 2~3mm, and the noncrushed waste styrofoam powder is stored in storage tanks(A,1,2,2-1-1,2-2,2-3,3). The waste styrofoam powder 12kg, waste sponge 5kg, noncombustible liquid corresponding phosphate composite 3kg~5kg, cement 100kg, charcoal 40kg, water 50l-55l are mixed and the mixture is extruded by an extruder(6-1) at 3~5atm(B,6). The molded article is moved to a heating chamber of 120~150°C and transfer rollers, cut in the cutting machine to 1800~2400m, cured in a cooling chamber(9-1), and cut and packed according to purpose(9,10).</p> |
