Electrically conductive resin composition and preparation method thereof

Abstract

The invention relates to an electrically conductive resin composition and a preparation method thereof. The electrically conductive resin composition contains: a first copolymer having an average rubber particle diameter of 1 [mu]m to 5 [mu]m, at 5 wt% to 30 wt%; a second copolymer having an average rubber particle diameter of 0.1 [mu]m to 1 [mu]m, at 20 wt% to 60 wt%; a conductive filler at 1 wt%to 15 wt%; a rubber component at 4 wt% to 20 wt%; and an olefin-based polymer at 4 wt% to 25 wt%.

Description

technical field [0001] The present invention relates to a conductive resin composition and a preparation method thereof, and more particularly, to a conductive resin composition which can be molded into a product excellent in bending characteristics and a preparation method thereof. [0002] And, the present invention relates to a conductive resin composition that can be molded into a product that minimizes a sloughing phenomenon caused by detachment of a conductive filler, and a method for preparing the same. Background technique [0003] Thermoplastic resins are plastics that soften when heated and become plastic when cooled. The above-mentioned thermoplastic resins have excellent processability and moldability, so they are widely used in various household products, office automation equipment, electrical and electronic products, automotive parts, etc. [0004] Also, attempts to use the above-mentioned thermoplastic resins as high value-added materials by adding special p...

Problems solved by technology

However, since the above-mentioned resin composition is basically thermoplastic, it should be able to be freely molded according to the shape of the final product, but when the product is molded, the dispersion of the carbon nanotubes dispersed in the above-mentioned resin composition needs to have more The bent portion with high elongation becomes non-uniform, and the conductivity at the bent portion is significantly lowered or cracks such as cracks occur, so it is difficult to apply to products and parts that require precise molding, etc., and cannot be used for Sheets thinned by high tensile provide required levels of flexural strength and impact resistance
