<p>A consecutive manufacturing method of fire-retard prefabricate panel is provided to mass-produce light and eco-friendly prefabricate fire-retard panel having excellent fire-retard, high elasticity and high strength. A consecutive manufacturing method of fire-retardant panel board by combining expandable minerals such as perlite and vermiculite, which has been heated, expanded and ground, with an inorganic adhesive for forming an article, and heating and pressuring the mixture, comprises: adding a predetermined sodium silicate and aluminum hydroxide to 5% of fibroid sepiolite powder, which is produced by particle-grinding expanded and foamed fibroid sepiolite, together with 40% of perlite and 35% of vermiculite, which are expanded to at least 5mm and foamed previously, 3% of graphite, 2% of limestone and 15% of woody fiber, and then adding water to the resulted mixture in the amount of 2.5 times with respect to the total material, and heating the resultant at 60-70deg.C for mixing; after combining the mixture with 10% of an inorganic adhesive with respect to total amount in a reactor, molding the mixture by an extruder having performance of 5.5kg per 1cm^3; consecutively forming panels having thickness required for the fire-retard panel, which comprises primary press performed by laminating the prepared material on uneven panel cover molded by continual a number of punching and secondary press performed by 35kg/cm^2 in molding roller line of hot-air drying which is heated to 160deg.C after the primary press. The panel is tested for deformation by heating at 1300-1800deg.C for 1 to 3 hours before sale at a market.</p> |
