The invention discloses fireproof fluorocarbon powder coating for aluminum panel curtain walls and a preparation method thereof. The fireproof fluorocarbon powder coating for aluminum panel curtain walls comprises, by weight, 300-350 parts of polyvinylidene fluoride, 210-250 parts of polyester resin, 280-350 parts of a flame retardant, 50-70 parts of chlorinated paraffin, 20-30 parts of antimony trioxide, 5-10 parts of nano magnesium hydroxide, 10-30 parts of composite zinc phosphate, 10-15 parts of mica powder, 1.5-2.5 parts of a defoaming agent, 25-30 parts of titanium dioxide, 40-60 parts of triglycidyl isocyanurate curing agent, 40-60 parts of precipitated barium sulfate, 5-10 parts of a leveling agent, and 3-6 parts of wax powder. The fireproof fluorocarbon powder coating for aluminumpanel curtain walls has the advantages that a coating layer of the fireproof fluorocarbon powder coating is imparted flame retardance, heat insulation, fire resistance and good decoration at the premise that excellent weatherability, high light-holding rate, good acid and base resistance, and good aging resistance are ensured, and the fireproof fluorocarbon powder coating is new-generation greenhigh-performance decorating coating.
