▎ 摘　　要

NOVELTY - Graphene high-performance heat-conducting powder coating comprises 30-40 pts. wt. saturated polyester resin, 20-30 pts. wt. acid resin, 2-10 pts. wt. curing agent, 1-5 pts. wt. graphene, 10-20 pts. wt. heat conducting filler, 5-10 pts. wt. pigment filler, and 5-5 pts. wt. zinc oxide. USE - Graphene high performance heat-conducting powder coating. Uses include but are not limited to CPU LED lamp, electric appliance, cabinet, wire cable, radiator, fan fan, heat pipeline, textile, tank, industrial device, building, water and box. ADVANTAGE - The graphene high performance heat-conducting powder coating: utilizes acrylic resin that improves the mechanical property and acid-alkali resistance of the saturated polyester coating; utilizes the crosslinked network formed by acrylic resin curing, which improves the heat conducting efficiency of the paint film surface and improves the uniformity of the coating heat conducting, and coating mechanical property; and utilizes the graphene, which does not perform multi-modification to the graphene material, avoids introducing structure defect, and only uses the graphene surface, which cooperates with the heat conductive filler (boron nitride and aluminum nitride), and thus improves the wear resistance and mechanical strength of coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing graphene high-performance thermally conductive powder coating comprising (i) introducing into dispersant under high-speed stirring at room temperature for 40-90 minutes, obtaining premix, (ii) heating screw cylinder of mixing and extruding dispersing device to 100-120 degreesC, adjusting screw speed to 48-50 HZ, where screw speed is stable, starting feeder, extruding mixture in the hopper by screw in screw barrel; (iii) cooling extruded mixture, When the mixed material is sufficiently cooled, introducing mixed material to a tablet press for crushing; (iv) introducing mixed material after crushing treatment into a grinder to be ground through a 250-mesh sieve to obtain the target product.
