▎ 摘　　要

NOVELTY - White graphene modified polystyrene composite material comprises 0.5-10 pts. wt. polymer modified white graphene, 90-110 pts. wt. styrene, 0.05-2 pts. wt. flame retardant, 0.05-2 pts. wt. antioxidant and 0.01-0.1 pts. wt. initiator. USE - Used as white graphene modified polystyrene composite material. ADVANTAGE - The material: has high flame retardancy, smoke suppressing property and high mechanical strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing white graphene modified polystyrene composite material comprising adding styrene, polymer modified white graphene, flame retardant, antioxidant and initiator, mixing under inert gas atmosphere and reacting at 80-90 degrees C for 3-6 hours to obtain reaction solution, mixing reaction solution with 100-150 pts. wt. dispersion medium, pouring into ethanol, precipitating, collecting the precipitate and then drying to obtain final product.
