▎ 摘　　要

NOVELTY - A modified white graphene composite polypropylene material and preparation method comprises 1-3 pts. wt. barium sulfate crystal whisker, 3-12 pts. wt. flame retardant, 10-16 pts. wt. antistatic agent, 4-8 pts. wt. modified white graphene, 6-12 pts. wt. impact modifier, 0.6-1.2 pts. wt. antioxidant, 0.6-1.2 pts. wt. dispersant, 0.5-1 pt. wt. nano calcium carbonate, 0.7-1.4 pts. wt. nano ceramic powder, 0.2-0.5 pt. wt. lubricant, 0.4-0.8 pt. wt. surfactant and 60-120 pts. wt. polypropylene. USE - Modified white graphene composite polypropylene material and preparation method used for industrial media transport. ADVANTAGE - The product has pure texture, thermal conductivity, chemical inertness, no toxicity, simple whole processing method, high heat resistance, better outer impact and other mechanical properties and good mechanical property, processing performance and electric insulativity, and improves wear resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the modified white graphene composite polypropylene material comprising grinding barium sulfate crystal whisker, nano calcium carbonate, nano ceramic powder, dispersant and lubricant by colloid mill, mixing with remaining materials into high speed mixing machine at 140-170 degrees C, heating, putting mixed material into extruder, extrusion molding using extruder at 140-180 degrees C, standing at room temperature for 15-30 minutes, cleaning surface, removing redundant edge sealing strip, and packing.
