▎ 摘　　要

NOVELTY - Polyester transparent powder coating comprises polyester resin, diethanolamine, methyl acrylate, trimethylolpropane, catalyst, stearic acid, barium sulfate, calcium carbonate, silicon dioxide, graphene, curing agent, dispersant, flatting agent, light stabilizer and antifoaming agent at the mass ratio of 40-100:1-3: 3-8:1-5: 2-6:0.1-1: 5-10:1-5: 5- 15:1-3:1-5:1-2:1-2:1-2:1-5. USE - Used as polyester transparent powder coating. ADVANTAGE - The polyester transparent powder coating: has high transparency and excellent leveling property, coating adhesion strength is very high and smooth. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the polyester transparent powder coating, comprising (i) mixing barium sulfate, calcium carbonate, silicon dioxide, graphene, stirring for 5-15 minutes at 100-150degrees Celsius to obtain the pre-mixed filler; (ii) mixing the polyester resin, premixed filler, curing agent, dispersant, flatting agent, light stabilizer, antifoaming agent, stirring for 1-2 hours at 65-75degrees Celsius to obtain the premix a; (iii) adding the diethanol amine into methanol, stirring uniformly, adding methyl acrylate, stirring for 2-4 hours at 40-50degrees Celsius, vacuum extracting and filtering, adding to trimethylolpropane, stirring for 1-2 hours at 50-60degrees Celsius, adding catalyst, stirring for 1-2 hours at 100-150degrees Celsius, rotating and evaporating for 1-2 hours, adding stearic acid to continuously rotate and evaporate for 1-2 hours to obtain the pre-mixed material b; and (iv) adding premix b into the premix a, continuously stirring for 10-20 hours, cooling to room temperature, taking out the mixture, melting and extruding, tableting, cooling, fine crushing, and sieving to obtain the polyester transparent powder coating.
