A METHOD FOR PREPARING CARBON NANO TUBE REINFORCED POLYPROPYLENE

摘要

PURPOSE: A manufacturing method of a CNT/PP composite material is provided to improve mechanical properties of the composite material, and to obtain the excellent CNT/PP composite material with excellent dispersity. CONSTITUTION: A manufacturing method of a CNT/PP composite material comprises a step of manufacturing a PP powder/xylene mixture; a step of stirring the mixture at 100-150 deg. C for 1-3 hours; a step of manufacturing a CNT/xylene dispersion solution by mixing a carbon nanotubes(CNT) and xylene; a step of injecting swollen the CNT/xylene dispersed solution into the swollen PP powder/xylene mixture; a step of ultra-wave dispersing the result; and a step of removing solvent, deaerating the solvent, and manufacturing final CNT/PP powder.
