NOVELTY - A main plastic composite material backlight source heat conducting glue frame comprises 80-90 wt.% main plastic, 8-18 wt.% filler, 0.2-1 wt.% three-dimensional graphene, 0.5-5 wt.% dispersant, and 0.2-0.4 wt.% antioxidant. USE - Main plastic composite material backlight source heat conducting glue frame. ADVANTAGE - The frame has simple preparation process, easy control, wide source of raw material, low production cost, convenient machine forming, and high freedom of product design. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of main plastic composite material backlight source heat conducting glue frame comprising weighing raw materials; subjecting main body plastic for heat treatment to obtain heat treated material; grinding filler to obtain nanofiller; stirring three-dimensional graphene, dispersant, antioxidant, heat treated material obtained in second step, and nanofiller at high speed to obtain mixed material in sealed stirrer; putting mixed material in double screw extruder for extruding, and granulating; and drying granules, cooling and shaping.
