PURPOSE: An environment-friendly inorganic sheet is provided to ensure excellent fire retardancy and processability, and to prevent the emission of poisonous gas in the fire. CONSTITUTION: An environment-friendly inorganic sheet includes a pair of TPU sheets(10) consisting of inorganic flame retardant and TPU resin, and inorganic fabric(20) adhered between the TPU sheets. A method for preparing the inorganic sheet comprises the steps of: forming a flame retardant resin composition; preparing a bi-layer TPU sheet using the flame retardant resin composition; putting inorganic fabric between dual structure TPU sheets to perform adhesion; and injecting the TPU sheet in which the inorganic fabric is adhered, into a mold to form an inorganic sheet. |
