▎ 摘 要
NOVELTY - Preparation of powder coating anti-scratch hardening agent comprises mixing the graphene in a magnetic field intensity of 600-800 Gs, and ultrasonic dispersing for 1-2 hours; and adding polyethylene wax and vanadium diboride, placing into a sealable ball mill, vacuumizing, charging temperature at 75-85 degrees C, and milling for 4-6 hours. USE - Method for preparing powder coating anti-scratch hardening agent. ADVANTAGE - The hardening agent reduces surface gloss and ensures product quality.
