Description of the Invention: [Technical Field] The present invention relates to a highly conductive polymer mixture comprising a carbon composite material, and more particularly to a carbon comprising excellent electrical conductivity A polymer composition of a composite material. [Prior Art] Thermoplastic resins have excellent processability and plasticity, and have been used in various industrial fields, including various household items, office automation devices, and electric/electronic products. Further, depending on the form and characteristics of the product using the thermoplastic resin, the thermoplastic resin is continually attempted to have a special property other than the excellent workability and plasticity, so that the thermoplastic resin can be used as a material of high added value. In particular, various attempts have been made to impart conductivity to thermoplastic resins, so that the resulting conductive thermoplastic resin can be used to cause electromagnetic interference (ElectroMagnetic Interference, EMI) in automobiles, various electric devices, electronic assemblies or electrical displays. The characteristics of the shield. In general, such a conductive thermoplastic resin is produced by using a thermoplastic resin composition containing a conductive additive (including carbon black, carbon fiber, metal powder, metal coated mineral powder, metal fiber, etc.). . However, unless a significant amount of such a conductive additive is added, it is difficult to ensure that the conductive thermoplastic resin has a desired degree of conductivity. Furthermore, due to the introduction of a large amount of inorganic materials, the use of a polymer composite of a carbonaceous material (e.g., carbon black or carbon fiber) causes an increase in hardness of the resin, a high surface roughness, and a decrease in physical properties of 201035996. Moreover, such polymer composite materials are difficult to achieve the desired high conductivity. Further, it is difficult to foam during the production of the polymer composite due to the introduction of the additive. At the same time, carbon nanotubes have also been attempted as conductive additives to impart excellent electrical conductivity to such conductive thermoplastic resins. However, when the carbon nanotube is mixed with a thermoplastic resin and then the resulting ruthenium mixture is injected to obtain a conductive hot resin, the shear stress generated between the injection processes causes the carbon nanotube to be agglomerated or arranged. The carbon nanotubes are poorly dispersed in the conductive thermoplastic resin. Thus, it is difficult to obtain sufficient conductivity. In this case, Korean Patent No. 7G6652 discloses a conductive thermoplastic resin group containing J parts by weight to 99 parts by weight of a thermoplastic resin; 0" by weight to 10 4 parts by weight of carbon naphthalene Rice tube; organic nano-clay (nanoclay) in m parts by weight to 1 inch weight. In addition, 'Korean Early Patent Publication No. _52657 discloses a composition comprising 99.6 parts by weight to 1 part by weight of at least one type of thermoplastic resin; 〇 part by weight to 5 parts by weight of at least one type of rubber Elastomer; 〇 2 parts by weight to parts by weight of carbon nanofibrils; 〇 2 parts by weight to ι by weight of at least one type of particulate carbon compound (preferably carbon black or graphite) And 〇 〇 by weight to 50 parts by weight of at least one filler and/or reinforcing material. However, in the above composition, the carbon nanotubes are maximized. It is still difficult to disperse the carbon nanotubes in the resin. In addition, it is necessary to introduce a large amount of carbon nanotubes 5 201035996 to achieve electrical conductivity. Therefore, the consumption of expensive materials is increased compared to other known compositions using carbonaceous materials such as carbon black or carbon fibers, resulting in undesirable cost benefits.
