▎ 摘　　要

NOVELTY - A multi-composite thermal conductive functional masterbatch comprises 5-85 pts. wt. graphene, 0-80 pts. wt. ultrafine thermal conductive filler, 0.5-1 pt. wt. antioxidant, 0.8-1.6 pts. wt. dispersant, 0.4-0.8 pt. wt. lubricant, and 5-40 pts. wt. carrier. USE - Multi-composite thermal conductive functional masterbatch is used for modifying plastic. ADVANTAGE - The multi-composite thermal conductive functional masterbatch has excellent mechanical characteristics, heat conductivity, and thermal stability, low stacking density, and particle diameter of 5 mu m, and is economically prepared with reduced dust emission by a simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of multi-composite thermal conductive functional masterbatch, which involves mixing graphene, ultrafine thermal conductive filler, carrier, antioxidant, lubricant and dispersant, extruding, and granulating.
