▎ 摘　　要

NOVELTY - A white graphene modified polycarbonate masterbatch comprises 100 pts. wt. polycarbonate particles, 0.5-10 pts. wt. modified white graphene, 0.05-0.2 pt. wt. flame retardant and 0.1-0.4 pt. wt. antioxidant. The modified white graphene is 2-10 layer white graphene subjected to surface lipophilic treatment and modified by polymer coating in-situ polymerization. USE - White graphene modified polycarbonate masterbatch. ADVANTAGE - The method is simple and low-cost. The product has improved flame retardance and loophole impact intensity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of white graphene modified polycarbonate masterbatch comprising taking polycarbonate, drying for 6-12 hours at 100-150 degrees C, adding remaining raw materials, mixing for 5-20 minutes, and extruding and granulating.
