▎ 摘　　要

NOVELTY - White graphene modified polyvinyl chloride composite material comprises 0.5-10 pts. wt. high polymer-modified white graphene, 90-110 pts. wt. vinyl chloride, 0.01-0.08 pts. wt. dispersing agent, 0.08-0.12 pts. wt. first initiator, and 130-160 pts. wt. water. USE - Used as white graphene modified polyvinyl chloride composite material. ADVANTAGE - The composite material has high thermal stability, cold resistance and high mechanical strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing white graphene modified polyvinyl chloride composite material comprising mixing high polymer modified white graphene, vinyl chloride, dispersing agent, first initiator and water at 40-70 degrees C, reacting under the conditions of pressure of 0.8-1.2 MPa, when the pressure in the reactor is reduced to 0.1-0.4 MPa, the reaction is stopped, centrifugating and drying.
