A thermoplastic resin composition is provided to ensure low melt viscosity and excellent flowability and to produce a molded product capable of being easily wet-plated even without performing chemical etching on the surface of the molded product. A thermoplastic resin composition is prepared by the steps of: charging polyolefinic resins into a reactor of 180-300°C to melt the resins; thereto adding 10-200 parts by weight of a plasticizer, 1-30 parts by weight of silicone oils, and 50-400 parts by weight of stone powder based on 100 parts by weight of the polyolefinic resins, wherein the plasticizer provides softness to the resins to increase moldability, the silicone oils provide fluidity and an antifoaming property to the resins to improve flowability, and the stone powder enhances specific gravity, effectively fills the composition in a mold during a rotational molding process to increase moldability, and enables wet plastic plating; mixing and stirring the admixture homogeneously; and cooling and solidifying the resultant.
