MANUFACTURING METHOD OF SEMI-ELECTRIC SHEET FOR POWER CABLE SHIELD

A method for manufacturing a semi-electric sheet for a power cable is provided to improve electric and mechanical characteristics by using a carbon nanotube with high dispersion. A method for manufacturing a semi-electric sheet for a power cable includes the steps of: generating an EEA(Ethylene Ethyl Acrylate) solution by adding EEA to a good solvent and agitating the solvent; generating a carbon nanotube dispersion solution by adding carbon nanotubes to the good solvent and evenly dispersing the carbon nanotubes; evenly mixing the EEA solution and the carbon nanotube solution; generating a precipitate by adding a non-solvent to the mixture to precipitate the EEA to which the carbon nanotubes are dispersed; removing the solution included in the precipitate by filtering and drying the generated precipitate; and adding a cross-linking agent to the dried precipitate, mixing the added precipitate, and then compressing the precipitate in a sheet shape, wherein the good solvent is any one selected from a group consisting of xylene, propanol, octanol, hexane, heptane, cyclohexane, benzene, acetone, and a tetrahydrofuran.
