NOVELTY - Powder coating comprises 70-90 pts. wt. bisphenol A epoxy resin, 20-30 pts. wt. modified potassium tetratitanate whiskers, 10-20 pts. wt. sericite powder, 8-12 pts. wt. graphene, 25-35 pts. wt. superfine barium, 20-40 pts. wt. titanium dioxide, 2-6 pts. wt. leveling agent, 2-4 pts. wt. dispersant, 1-5 pts. wt. defoamer and 5-11 pts. wt. curing agent. USE - The powder coating is used in harsh outdoor environments such as outdoor containers, construction machinery and ships. ADVANTAGE - The powder coating has excellent acid and alkali resistance, salt spray resistance, weather resistance, water resistance and other characteristics, and has excellent adhesion to the substrate and excellent adhesion to steel structures. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the powder coating, involving adding modified potassium tetratitanate whiskers and other raw materials into a high-speed mixer, mixing at a temperature of 40-60 degrees C and rotation speed of 500-600 rpm for 10-20 minutes to obtain mixture, adding the mixture to a twin-screw extruder with a rotation speed of 200-300 rpm, where the temperature of the extruder cavity is 100-120 degrees C, and the temperature of the discharge port is 100-120 degrees C, performing melt extrusion, cooling and pulverizing to 200 meshes to obtain powder coating.
