▎ 摘　　要

NOVELTY - Electromagnetic shielding powder coating comprises 40-65 wt.% graphene polyester resin, 4-6 wt.% curing agent, 0.8-1.2 wt.% leveling agent, 0.7-30 wt.% pigment, 3-15 wt.% inorganic filler, 20-35 wt.% modified wave absorbing agent, and 0-2 wt.% auxiliary agent. USE - Used as electromagnetic shielding powder coating. ADVANTAGE - Compared with the prior art, the coating uses silica to coat the wave absorbing agent and chemically modifies it with a coupling agent, and simultaneously adds a coupling agent to the graphene resin, In this way, it is convenient for the wave absorber, filler silica, etc. to have good compatibility with the polyester resin matrix. Significantly improves the dispersion of absorbers and fillers in coatings. The powder coating can attenuate the electromagnetic radiation signal of 10-25db after the coating obtained by baking and curing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of electromagnetic shielding powder coating, comprising adding the raw materials into a mixing tank, fully pre-mixing, extruding through extruder, tableting, crushing, grinding, sieving and packaging finished product.
