▎ 摘　　要

NOVELTY - A graphene transparent powder coating for MDF board, comprises 30-60 wt.% polyester resin, 24-48 wt.% epoxy resin, 0.8-1.2 wt.% leveling agent, 0.5-1.0 wt.% brightening agent, 0.5-1.0 wt.% wax powder, 0.3-0.8 wt.% benzoin, 1.0-2.0 wt.% frictional electrification agent, and 0.02-0.1 wt.% graphene. USE - Graphene transparent powder coating for MDF board (claimed). ADVANTAGE - The graphene transparent powder coating has high leveling effect, high gloss, high adhesion effect and high flexibility, excellent water resistance, high conductivity by adding graphene, does not produce Faraday effect, and does not produce free ions. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of graphene transparent powder coating for MDF board, which involves mixing polyester resin, epoxy resin, leveling agent, brightening agent, wax powder, benzoin, friction electrification agent and graphene in a powder state into a mixer, placing mixture in twin-screw extruder for mixed extrusion, cooling, crushing, and grinding; and (2) process for spraying MDF board graphene transparent powder coating by friction gun carrying out early treatment of MDF board, spraying graphene transparent powder by friction gun, infrared oven curing at 130-150 degrees C for 15-20 minutes and taking out sample.
