Incombustibility composition for a board of an access floor, method for preparing the board of the access floor using the same and board for incombustibility access floor

摘要

Disclosed is an incombustible composition for an access floor board, a method of producing the access floor board using the incombustible composition, and the incombustible access floor board using the incombustible composition. The incombustible composition includes 1 to 90 wt% of stone powder, 1 to 30 wt% of curing fire-retardant resin, 1 to 80 wt% of organic or inorganic fiber, and 1 to 80 wt% of fly ash or bottom ash. Therefore, the incombustible composition is advantageous in that it is environmentally-friendly because it contains waste materials, and that it has excellent hardness, strength, and water resistance. Other advantages are that its production costs are relatively low, and that it has excellent incombustibility, depending on contents of the components constituting the incombustible composition.
