PET, 4-5 pts. wt. methacrylic acid ester-acrylic ester copolymer, 8-10 pts. wt. potassium hexatitanate whisker, 5-6 pts. wt. multi-walled carbon nanotube, 1-2 pts. wt. graphene, 20-24 pts. wt. nano magnesium oxide, 0.1-0.2 pts. wt. zinc acetylacetonate, 1-1.5 pts. wt. imidazole hexafluorophosphate ionic liquid, 1-2 pts. wt. silane coupling agent, 0.5-0.6 pts. wt. antioxidant, 0.1-0.2 pts. wt. light stabilizer and 30-40 pts. wt. deionized water. USE - Used as light emitting diode heat abstractor material. ADVANTAGE - The heat abstractor material: comprises high dispersibility components; has heat guide coefficient, high molecular plasticity and good compatibility; has high heat radiating effect; increases mechanical property; and is durable and suitable for preparing LED package. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of heat abstractor material comprising (a) mixing imidazole hexafluorophosphate ion liquid and deionized water, heating in an oil bath at 50-60 degrees C, mixture for 25-30 minutes, heating to 70-80 degrees C, adding hexapotassium titanate crystal whisker, multi-walled carbon nanotube and graphene, ultrasonically stirring at a constant-temperature for 3-4 hours, stirring, drying to remove water, grinding into powder, dispersing to obtain ionic liquid modified hexapotassium titanate crystal whisker/carbon nanotube composite powder, (b) mixing PC, PET, methacrylic acid ester-acrylic ester copolymer, nano magnesium oxide, zinc acetylacetonate, antioxidant, light stabilizer and silane coupling agent at a high speed, granulating in a double screw extruder, (c) taking the composite powder and the remaining amount of silane coupling agent, stirring uniformly, (d) taking the product of the step (b) into a feeding extruder, adding composite powder of the step (c) via side feeding, extruding and granulating, cooling and injection molding.
