<p>Disclosed is a lightweight, noise-absorbable and adiabatic polyester panel, which has excellent fire-retardancy, and horizontal and vertical drag forces. The noise-absorbable and adiabatic panel includes a middle plate, having a plurality of strips attached to each other and then subjected to a fire-retardant treating process using a fire-retardant agent liquid. Additionally, first and second exterior plates are respectively attached to upper and lower surfaces of the middle plate in such a way that fibers of the strips run perpendicular with respect to the first and second exterior plates. In this regard, the strips are formed by perpendicularly cutting a horizontally piled polyester synthetic fiber so that the strips each have a predetermined length of. Furthermore, the middle plate is subjected to a fire-retardant treating process using the fire-retardant agent liquid, including 55 to 75 wt % of sodium silicate solution with a molar ratio of 2.1 to 2.9 ((SiO<SUB>2</SUB>/Na<SUB>2</SUB>O)x1.032), 0.5 to 7 wt % of carboxymethyl cellulose, 0.1 to 5 wt % of polyvinyl alcohol, and water. Accordingly, the noise-absorbable and adiabatic panel including the middle plate is usefully applied to lightweight construction interior and exterior material with excellent vertical and horizontal drag forces and fire-retardancy.</p> |
