  • Publication number: 20030236041
    Abstract: Disclosed are a fire retardant laminated sheet and a manufacturing method thereof. The laminated sheet for various interior applications exhibits improved fire retardancy, so it does not burn in a fire. Such a fire retardant laminated sheet is manufactured by impregnating a fire retardant material with an impregnant containing phenolic resin, to have 25 to 35% resin impregnated by weight, obtaining a sheet base. Then, a melamine resin impregnated paper is stacked on one or both faces of the sheet base thus obtained, and the resultant stacked paper is molded under heat and pressure, using a press, at 130 to 140° C. for 15 to 30 min under a pressure of 50 to 60 kgf/cm2.
