Abstract: PURPOSE: An inorganic filling coated with multi-layered polymer manufacturing method and paper using the same method are provided to enhance the intensity of paper by absorbing different polymer materials with different ion on the surface of inorganic filling and forming multi-layered polymer on the filling. CONSTITUTION: An inorganic filling coated with multi-layered polymer manufacturing method comprises the following steps. In a reaction tub, a particle for filling which shows anionic features is dispersed by distilled water (S110). By putting cationic polymer material into the tub, the cationic polymer material is absorbed in the surface of the filling static-electrically (S120). By getting the distilled water and the cationic polymer material which is not absorbed out, distilled water is put into the tub to re spread the filling (S130). By putting anionic polymer material to the tub, the anionic polymer material is absorbed on the surface of the cationic polymer static-electrically (S140). In the tub, the anionic polymer material left is discharged and distilled water is put into the tub to re spread the filling (S150). By putting the cationic polymer material in the tub, the cationic polymer material is absorbed on the surface of the anionic polymer material static-electrically (S160). After the distilled water and the cationic polymer material left are discharged, distilled water is put into the tub to re spread the filling (S170).
