Abstract
PURPOSE: To obtain a flame-retardant fiber board having a low density and a light weight, suitable for wall materials and ceiling materials and further useful as a flameproof material, a sound-absorbing board and a sound-absorbing material, by mixing a pulp phosphate ester, rock wool, etc., and then forming the board from the mixture. CONSTITUTION: This flame-retardant fiber board is obtained by mixing a pulp phosphate ester with rock wool or the pulp phosphate ester with rock wool and glass fibers and then making the board from the mixture. For example, the flame-retardant fiber board is obtained by reacting urea and phosphoric acid, dissolving the obtained polyphosphoric acid ammonium salt in water, further dissolving several percent of urea in the aqueous solution to prepare the phosphate ester-forming agent solution, immersing pulp in the prepared agent solution, leaving the pulp, pulling up the pulp, drying the pulp, heating the pulp at an esterification reaction temperature (140 deg.C), washing the reaction product with water, charging the washed product into a beater, further charging rock wool into the beater, disintegrating the mixture and then making the board from the disintegrated product.
