Patent ID: 11912868

Abstract:
The present invention relates to a conductive concentrated resin composition including (a) 100 parts by weight of a base resin including 50 to 95% by weight of a polyamide resin, 2.5 to 20% by weight of a polar polymer, and 2.5 to 30% by weight of a non-polar polymer, (b) 10 to parts by weight of a carbon nanofibril, (c) 0.5 to 5 parts by weight of a carbon nanoplate, and (d) 0.5 to 4 parts by weight of nanoclay; a conductive polyamide resin composition including the conductive concentrated resin composition; a method of preparing the conductive concentrated resin composition; and a molded article including the conductive polyamide resin composition.When a polyamide alloy resin composition is prepared using the conductive concentrated resin composition of the present invention, compatibility between compositions and dispersion stability may be improved, thereby significantly increasing moisture stability while maintaining mechanical strength, conductivity, heat resistance, and appearance properties equal or superior to those of a conventional conductive polyamide alloy resin composition.
